Background: Cardiotoxicity is one of the emerging health-care issues worldwide and mortality due to this is increasing exponentially. Oxidative stress, myocardial inflammation, and damage to the cardiac membrane are major causative attributes for this toxicity. Isoproterenol (ISO)-induced cardiotoxicity is a well-established and accepted model to estimate innovative cardioprotective agents, as it exhibits several morphological and biochemical aberrations in the myocardium of rat that is comparable with those detected in clinical practice. Objectives: In the present study, we explored the cardioprotective effect of swerchirin (SW) extracted from Swertia chirayita in the ISO model. Materials and Methods: SW was isolated from S. chirayita, characterized by high-performance thin-layer chromatography-mass spectrometry, 1H-nuclear magnetic resonance (NMR), 13C-NMR, and high-performance liquid chromatography techniques. The in-vitro study was performed for 2,2-Diphenyl-1-picrylhydrazyl and nitric oxide scavenging activity to explore the antioxidant capacity. In silico study was performed to ascertain the binding affinity of SW with antioxidant enzymes. The in-vivo study was performed to explore the cardioprotective activity in the ISO-induced cardiotoxic model. Results: The in vitro studies showed the significant antioxidant potential of SW whereas the in silico study revealed its effective binding into the catalytic pocket domain of superoxide dismutase and catalase. The in vivo study showed a significant improvement in antioxidant enzymes and a reduction in serum glutamic-oxaloacetate transaminase and lipid profile. Further, SW also significantly reversed the histopathological aberrations in a dose-dependent manner. Conclusion: Findings of the study showed a significant cardioprotective effect of SW against ISO-induced cardiac damage.

Jan-Mar 2022, 18(77):168-174
Background: The cerebral ischemic stroke befalls in response to the abrupt occlusion of blood vessels that leads to deprived oxygen and glucose in brain and causes brain injuries. Stroke is associated with higher morbidity and mortality rate globally. Syringin is a bioactive compound from Eleutherococcus senticosus and possesses plentiful biological actions. Objectives: In this research work, we envisioned to observe the neuroprotective actions of syringin against ischemic-reperfusion (I/R)-provoked ischemic stroke in rats. Materials and Methods: The focal cerebral I/R injuries were roused to the male Wistar rats through the middle coronary artery occlusion (MCAO) technique. The syringin (10, 25, and 50 mg/kg) was administered to the rats through intragastric route for 7 successive days prior to MCAO and another 3 days after MCAO. Sham rats were administered with usual diet. The neurological score and parameters were measured by standard methods. The status of inflammatory cytokines and mediators in both serum and brain tissues was considered by commercial assay kits. The mRNA expression of toll-like receptor (TLR) 4, MyD88, Fas, and FasL was inspected by reverse transcription–polymerase chain reaction technique. Results: The syringin administration to I/R rats established the lessened neurological score and parameters. Syringin supplementation was meritoriously suppressed the levels of the inflammatory cytokine, i.e., interleukin (IL)-1 β, IL-6, and tumor necrosis factor-α and enhanced the IL-10 status in I/R rats. Syringin abridged the inflammatory mediators like cyclooxygenase-2, prostaglandin-2, and nuclear factor kappa B levels in the serum and brain tissues. The mRNA expression of TLR4, MyD88, Fas, and FasL was noticeably downregulated by the syringin. Conclusion: Taken together, our results showed the curative role of syringin against ischemic stroke in rats. Syringin can be an auspicious anti-stroke agent in future to treat ischemic stroke.

Jan-Mar 2022, 18(77):233-241
Background: In the modern era of therapeutics, the proniosomal system has been identified as the most intriguing one among various novel systems, thus considerably enhancing the bioavailability of low-soluble drugs. The current study aimed to study the enhancement of therapeutic efficacy of topotecan (TPT) with curcumin (CUR) coadministration. Materials and Methods: We optimized the preparation of niosomes, concerning concentrations of lecithin, span 60, and cholesterol. Seventeen trials were proposed by the selected design. All these batches were initially evaluated only for entrapment efficacy (EE), vesicle size (VS), and percentage of TPT release by the end of 12 h. Analysis of variance and generated regression equations were assisted to study the significant variables and magnitude of impact. Results: The desirability of 0.893 was achieved with the optimum concentrations of selected independent variables in attaining the highest EE (90.393%), minimum VS (386.264 nm), and percentage of TPT release (98.614% at 12 h). TPT and CUR release from the optimized formulation were found to be anomalous or non-Fickian diffusion, as evident from the n value of Peppas model. The cytotoxic studies demonstrated that TPT and CUR in liposomal and free forms were found to be less cytotoxic on MCF-7 model cells. All these findings indicate that the coadministration of CUR with TPT proniosomes can be a promising strategy to enhance the antitumor treatment.

Jan-Mar 2022, 18(77):44-51
Aim: We aimed to monitor an acid polysaccharide with antioxidant activity. Materials and Methods: Three acidic polysaccharides (DAP-A40, DAP-A60, and DAP-A80) were extracted from D. aurantiacum imbricate by alkaline aqueous solution extraction and ethanol precipitation. The structure characterization and antioxidant activity in vitro and in vivo were examined. Results: The molecular weight (MW) of three polysaccharides was 1.70 mol5 Da, 5.78 mol4 Da, and 1.36 mol4 Da, respectively, by high-performance gel chromatography. The consequences of infrared spectrum displayed that three polysaccharides enclosed uronic acid and sulfuric acid groups. DAP-A40 and DAP-A60 were collected of α-configuration pyranose. DAP-A80 was composed of β-configuration pyranose. Antioxidant test exhibited that DAP-A80 had outstanding antioxidant activity. The half-maximal inhibitory concentration of DAP-A80 in dipping power and scavenging the 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), DPPH, and OH radicals was 163.5 μg/mL, 613.2 μg/mL, 583.2 μg/mL, and 365.1 μg/mL, respectively. The grades of correlation analysis showed that the ability of DAP-A80 to scavenge ABTS, DPPH, and OH radicals was negatively connected with the MW of polysaccharides and certainly correlated with the content of sulfate group. The results of in vivo experiments exposed that DAP-A80 might knowingly decline the formation of malondialdehyde. High levels of DAP-A80 could evocatively upsurge the activity of superoxide dismutase and GSH-Px in mouse serum. Conclusion: DAP-A80 has an antioxidant effect and can be reconnoitered as a health medicine and food.

Jan-Mar 2022, 18(77):242-246
Background: Thiazide diuretics are one of the most effective, least expensive antihypertensive medicines, however, they are associated with hypokalemia, which can complicate the outcome of care among hypertensive patients. The concurrent administration of a potassium-rich food such as date palm fruits (DPFs) could be an attractive strategy in ameliorating thiazide-induced hypokalemia. The objective of this preliminary study was to investigate the effect of concurrent administration of DPF with hydrochlorothiazide (HCT), a thiazide diuretic on serum potassium level and lipid profile. Materials and Methods: Thirty-six rats were used for this study and were divided into 6 experimental groups comprising control (normal saline), DPF only, HCT, 25 mg/kg plus HCT, 50 mg/kg plus HCT, and 100 mg/kg plus HCT. Animals were dosed daily for 4 weeks and at the end of the experiment, blood samples were collected and allowed to cloth. Subsequently serum were analyzed for potassium levels and lipid profile. Results: Results showed that DPFs produced significant weight loss compared to the control and HCT only groups. Furthermore, serum potassium levels were increased abolishing hypokalemia produced by HCT in all the combination treatments. Total cholesterol, triglyceride, and low-density lipoprotein levels were all attenuated by concurrent treatment with DPFs and HCT. Conclusion: Therefore, the present study demonstrates that co-administration of DPFs with HCT restored serum potassium levels in rats and hence alleviated the attendant HCT-induced hypokalemia.

Jan-Mar 2022, 18(77):103-111
Background: Rheumatoid arthritis is a chronic, common autoimmune disorder identified by progressive dysfunction of joints and cartilage damage. Oxypaeoniflorin (OPA), a Traditional Chinese Medicine monomer, has been reported for potential against inflammation and oxidative stress. Objectives: The objective of the study is to evaluate the potential of OPA against Freund complete adjuvant (FCA)-induced inflammatory pain in experimental arthritic rats. Materials and Methods: FCA was administered in female rats (Wistar strain) to induce polyarthritis, followed by 28 days of oral treatment with either vehicle, leflunomide (10 mg/Kg), or OPA (10, 20, and 40 mg/kg). Various parameters were assessed to determine the effect of OPA on pain and inflammatory pathway. Results: Adjuvant-induced arthritis (AIA)-induced elevated paw withdrawal latency and threshold suggested induction of arthritic pain. However, OPA (20 and 40 mg/kg) treatment diminished arthritic pain reflected by amelioration of hyperalgesia and allodynia. In addition, OPA showed an effective inhibition (P < 0.05) in FCA-induced alterations in alkaline phosphatase, alanine transaminase, aspartate aminotransferase, serum albumin, and C-reactive protein levels. The AIA-induced elevated oxido-nitrosative stress, protein levels of tumor necrosis factor-α, and interleukins in synovial tissue were effectively reduced (P < 0.05) by OPA. Moreover, OPA effectively downregulated (P < 0.05) enhanced nuclear factor-kappa beta (NF-κB), Ikβα, iNOs, and COX-2 mRNA expressions in synovial tissue. OPA also reduced histopathology alteration induced in the tibiotarsal joint by FCA. Conclusion: OPA exerts its antiarthritic property through inhibition of NF-κB/IκBα pathway to downregulate the activation of pro-inflammatory cytokines and inflammatory mediator thus, ameliorated arthritic inflammation and pain.

Jan-Mar 2022, 18(77):52-65
Background: Type 2 diabetes mellitus is a progressive polygenic disorder requiring a multi-targeted therapeutic approach. A polyherbal formula (PHF) comprised of four traditional herbs known for their anti-diabetic, anti-oxidant, and hepatoprotective activities were used in this study. Objectives: The purpose of this research was to find out the plausible mechanisms underlying the synergistic effects of PHF in an experimental setting of diabetes mellitus. Materials and Methods: PHF was evaluated for the presence of residual toxins, acute oral toxicity, and its effects on carbohydrate digestive enzymes. PHF (100, 200, and 300 mg/kg/p. o., respectively) was used to treat streptozotocin-induced diabetic rats for 12 weeks followed by glycemic, histopathological, biochemical, and ultrastructural changes measurement. mRNA levels of AMPK, insulin receptor substrate (IRS), phosphoinositide-3-phosphate kinase (PI3K), Akt, and glucose transporter 2 (GLUT2) were measured using real-time polymerase chain reaction. Results: In PHF, the residual toxins were absent. PHF inhibited the α-amylase (IC50 152.2 ± 9.3 μg/mL), and α-glucosidase (IC50 103.0 ± 0.81 μg/mL) activities in-vitro. Further, up to a dose of 2000 mg/kg, PHF showed no signs of mortality. PHF treatment significantly maintained the glycemic state, antioxidant status, lipid profile, hepatic-architecture, and ultrastructural alterations in diabetic rats. Similarly, diabetic rats showed detrimental effects on the mRNA level of AMPK and IRS-PI3K-Akt-GLUT2 signaling which were attenuated by PHF treatment. Immunohistochemical analysis also revealed an improvement in p-Akt expression after PHF treatment. Conclusion: In streptozotocin-induced diabetic rats, PHF improves glucose and lipid metabolism by attenuating hyperglycemia, hyperinsulinemia, dyslipidemia, insulin resistance, oxidative stress, inflammation, and deterioration of hepatic architecture possibly through AMPK mediated improvement in hepatic IRS-PI3K-Akt-GLUT2 signaling pathway.

Jan-Mar 2022, 18(77):94-102
Background: Breast cancer is one of the leading causes of cancer-related death among females in the world. Sesamol, which is an herbal phenolic compound, is investigated for its powerful antioxidant and anticancer motility. Sesamol induces growth arrest and apoptosis in malignant cells. However, its pharmaceutical significance is limited due to poor bioavailability. The self nanoemulsifying drug delivery system (SNEDDS) is a type of lipid nanocarrier system that is suitable for the encapsulation of lipophilic drug molecules. Objectives: In the present study, Sesamol-loaded SNEDDS were developed, identified, and assessed for the enhancement of its in vitro dissolution rate and anticancer efficacy. Materials and Methods: Based on the solubilization potential of sesamol, the oil (Isopropyl myristate, Isopropyl palmitate, Caprylic capric triglycerides, Sesame oil) surfactant (Span 80, and Tween 80), and cosurfactant (Poly Ethylene Glycol 400) were chosen for the formulation of Sesamol-loaded SNEDDS. SNEDDS were prepared by an aqueous titration technique. Developed formulations were characterized and assessed for thermodynamic stability, self nanoemulsification efficiency, droplet size, polydispersity index, zeta potential, surface morphology, refractive index, the percent of transmittance, and drug release profile. Results: In vitro dissolution rate of Sesamol was significantly enhanced from the optimized formulation in comparison with pure drug. The finalized formulation was selected for in vitro anticancer effects in human breast cancer cells (MCF-7) by 3-(4,5-dimethylthiazol-2-yl)-2,5-Diphenyl Tetrazolium Bromide (MTT) assay. MTT assay suggested remarkable anticancer efficacy of finalized Sesamol-loaded SNEDDS against MCF-7 cells compared with standard (Marketed preparation). Conclusion: The outcome of this study revealed the incredible potential of SNEDDS in the enhancement of in vitro dissolution rate and anticancer efficacy of the poorly soluble drug.

Jan-Mar 2022, 18(77):82-88
Objectives: In this study, we aimed to study the effect of total flavonoids extracted from Hippophae rhamnoides L. (TFH) on the activity of five CYP450 enzymes in rats by high-performance liquid chromatography (HPLC). We also studied the effect of TFH on the expression of CYP450 enzyme mRNA in rat liver using quantitative real-time PCR (qRT-PCR). Materials and Methods: TFH was orally administered to male rats once daily at doses of 100, 200, and 400 mg/kg/day for 14 days. We established HPLC method to detect the concentration of the analytes in the rat plasma. We used DAS software to calculate the pharmacokinetic parameters. Then, qRT-PCR was used to study the effect of TFH on the expression of CYP450 mRNA. Results: The pharmacokinetic analysis of theophylline in the TFH group revealed a short half-life (t1/2), a decrease in the area under the curve (AUC), and an increase in the value of plasma clearance (CL) (P < 0.05, P < 0.01). In the case of midazolam, t1/2 was prolonged, Cmax was increased (P < 0.05). Results from the PCR analysis indicate that TFH downregulated the expression of CYP3A4 mRNA and upregulated the expression of CYP1A2 mRNA. Conclusion: In conclusion, TFH might induce the activity of CYP1A2 and inhibit the activity of CYP3A4. Herb–drug interaction should be carefully considered when TFH is being used in combination with drugs metabolized by CYP1A2 and CYP3A4. SUMMARY

Hasan Saeed Alamri
Jan-Mar 2022, 18(77):128-132
Background: Crataegus aronia L. Syn: Azarolus (C. aronia) is a hawthorn species and a perennial bush native to Mediterranean regions. It is recognized for its high polyphenol content and potent antioxidant effects. Research was conducted to test the antidepressant activities of an aqueous extract of C. aronia in a chronic, unpredictable, mild stress-induced rat model. Materials and Methods: Thirty-two adult Wistar male rats were divided into four groups: A control group (no stress and no treatment), stress-model group (stress and no treatment), fluoxetine-treated stress group (stress and fluoxetine treatment), and C. aronia-treated stress group (stress and C. aronia treatment). Urine samples were collected at 0, 21, 36, and 51 days. Enzyme-linked immunosorbent assay kits were used to assess serotonin, norepinephrine (NE), and dopamine (DA) levels. Results: There was a decrease in serotonin levels 3 weeks after stress exposure, but urinary NE and DA levels increased. C. aronia significantly (P < 0.001) reversed the depressive-like symptoms in the rats according to the increased urinary levels of serotonin. Moreover, C. aronia also reduced urinary levels of urinary NE and DA. The neuromodulatory effects of C. aronia were comparable to that of fluoxetine. Conclusion: With its active ingredients of anthocyanins and procyanidins, C. aronia exhibits significant antidepressant-like activity in validated stressed rats, which may be related to its neuromodulatory effects on central monoamines.

Jan-Mar 2022, 18(77):226-232
Background: Tick and tick-borne diseases significantly affect the animal husbandry sector worldwide. To overcome this menace, chemically synthesized acaricides are being used. However, these acaricides are toxic to the animals, pose environmental threat and also have led to the development of resistance in ticks. Objectives: Search for safe and efficacious plant-based alternatives to the chemical acaricides and to assess chemical variability among intra-specific germplasms. Materials and Methods: Ageratum conyzoides L. samples were collected from different locations and pharmacognostic analysis was performed. The plant extract was subjected to chromatographic profiling and quantification of three bioactive markers precocene I, precocene II, and caryophyllene oxide followed by in vitro anti-tick activity through the adult immersion test. Results: Precocene I content ranged from 0.001% to 0.019% while precocene II and caryophyllene oxide content varied from 0.003% to 0.11%. In the Indus plain samples, adult tick mortality (%) ranged from 15.0 ± 2.9 to 78.5 ± 4.1, whereas in the Central India, it ranged from 30.0 ± 12.9 to 81.4 ± 7.7 at 8% concentration of plant extract. Precocene II showed weak positive correlation (r = 0.11) with tick mortality. The results indicate that there is considerable variation in the marker compounds content and anti-tick potential of the plant extracts analyzed. There is significant (P < 0.05) variation in marker compound content as well as anti-tick potential of A. conyzoides. Conclusion: The results indicate there apart from the analyzed marker compounds there might be some other phytomolecules playing a role in the tick mortality which needs further investigation.

Jan-Mar 2022, 18(77):112-120
Background: Polysaccharide biology, whose core is the structure, function, and edible value of polysaccharides, is regarded as the last great scientific frontier outside the field of protein and nucleic acid research. Materials and Methods: In this study, highperformance gelpermeation chromatography, high-performance liquid chromatography, gas chromatography–mass spectrometry, and nuclear magnetic resonance analysis were performed to identify the structure of a new polysaccharide isolated from Lyophyllum decastes (Fr.) Sing (LDS-1). The anticancer and immunomodulatory ability of the polysaccharides (LDS-1) was also investigated. Results: The results showed that the average molecular weight of LDS-1 was 8681 Da, and the ratio between glucose and galactose was 2:1. Structural analysis revealed four (1 →4)-α-D-Glcp moieties with branches at 6-O position, and the branches consisted of two (1 →6)-β-D–Galp moieties. Our results showed that LDS-1 exhibits immunological activity. At a concentration ranging from 2.5 to 25 μg/mL, LDS-1 could distinctly promote the growth of T lymphocyte, B lymphocyte, and RAW264.7 cells; increase the secretion of IgA, IgD, IgE, IgG, IgM, tumor necrosis factor (TNF)-α, TNF-β, and interleukin-2, and enhance the phagocytotic activity of RAW264.7 cells to phagocytize fluorescent microspheres, when compared with the blank control group (P < 0.01). Furthermore, under in vitro conditions, LDS-1 (2.5-20 μg/mL) exhibited significant antineoplastic activity (P < 0.01) against colon cancer cells (CT26.WT) and S180 cells when compared with the blank control group. However, the inhibition effect was different. The research for antineoplastic activity of LDS-1 in vivo indicated that the tumor inhibition rate was 54.32%. Conclusion: In conclusion, the polysaccharides of LDS-1 exhibited good biological activities, which shows that it can be used as an immunomodulator and an antitumor agent.

Weiwei Zhang, Jincheng Duan, Chunyan Ji, Zhengchun He, Guirong Shi, Meixian Guo, Xiaobo Liu
Jan-Mar 2022, 18(77):133-142
Background: Prior studies have revealed that crude Vicatia thibertica polysaccharide have the anti-fatigue effect, but the anti-fatigue effect and potential mechanism of purified polysaccharides endure blurred. Objectives: We intended to purify and gauge the anti-fatigue effects of a polysaccharide isolated from Vicatia thibertica polysaccharide 1 (VTP1). Materials and Methods: First, the exercise fatigue model was recognized in Kunming mice. After 14 days of continuous intragastric administration of VTP1 (50, 100, and 200 mg/kg/day), we assessed the anti-fatigue and antioxidant effects of VTP1 on fatigued mice. In addition, the effects of VTP1 on mitochondrial morphology of skeletal muscle of fatigue mice were detected by transmission electron microscopy. Meanwhile, the expression of mitochondrial DNA was noticed. Finally, using Western blot, immunohistochemistry, and real-time quantitative polymerase chain reaction, respectively, to sense the expression of sirttuin1, peroxisome proliferative activated receptor-γ coactivator 1α (PGC-1α), and nuclear respiratory factor 1 (NRF1). Results: VTP1 meaningly extends the time to exhaustion during weight-bearing swimming and improves the endurance and bodyweight of fatigued mice. Furthermore, VTP1 exerts antioxidant effects, reduces creatine kinase, blood urea nitrogen and lactate dehydrogenase in the serum, surges superoxide dismutase and cuts malondialdehyde in the liver. Meanwhile, VTP1 diminishes degeneration of mitochondria in the skeletal muscle of mice with exercise fatigue and improves the biosynthetic efficiency of mitochondria in skeletal muscle. Finally, VTP1 can upregulate the mRNA and protein expression of PGC-1α and NRF1. Conclusion: VTP1 has an anti-fatigue effect, and the effect may be mediated by the PGC-1α/NRF1 signaling pathway.

Nadta Sukkasem, Waranya Chatuphonprasert, Kanokwan Jarukamjorn
Jan-Mar 2022, 18(77):89-93
Background: Hesperidin and myricetin are anti-inflammatory and anti-oxidant flavonoids that have beneficial effects in fatty liver disease (FLD), but information regarding their effects on cytochrome P450 (CYP450) enzymes in FLD is limited. Objectives: This study determined the impacts of hesperidin and myricetin on CYP450 profiles in FLD mice. Materials and Methods: Adult female mice were fed a high fat diet (HFD, 60 kcal % fat of total food) with daily intragastrically administered ethanol (0.5 g/kg/day) in combination with either fenofibrate (40 mg/kg/day), hesperidin (50 and 200 mg/kg/day), or myricetin (50 and 200 mg/kg/day) for 60 consecutive days. Liver histomorphology was examined by oil red O staining. Hepatic enzyme activity and mRNA expression of CYP1A2, CYP2E1, CYP3A11, CYP3A13, and CYP4A11 were assessed. Results: HFD-induced hepatocellular damage was prevented by low dose hesperidin and myricetin. Expression of Cyp1a2, Cyp2e1, and Cyp4a11 mRNAs as well as CYP2E1 and CYP3A activities was significantly induced by HFD plus ethanol (HE) while Cyp3a13 expression was slightly increased. Fenofibrate and low dose hesperidin prevented HE-induced Cyp1a2 and Cyp2e1 expression while HE-induced Cyp4a11 expression was prevented by all treatments. The expression of Cyp3a13 was extensively suppressed by high-dose hesperidin and myricetin, and CYP2E1 and CYP3A activities were significantly decreased by all treatments. Conclusion: Alteration of CYP450 profiles by high doses of hesperidin and myricetin could lead to drug interactions. Nevertheless, low dose hesperidin prevented dysregulation of CYP450 expression in FLD and is a promising candidate for FLD treatment.

Jan-Mar 2022, 18(77):216-225
Background: Luteolin (Lut) is a natural flavonoid with low water solubility. Many studies have revealed that its antitumor effect is more understandable. Objectives: Synthesis of glycyrrhizin-coupled bovine serum albumin-loaded Lut nanoparticles (GL-BSA-Lut-Nps) to progress the water solubility, anticancer effect, liver targeting, cycle arrest, induction apoptosis, and regulating the metabolism of Lut. Materials and Methods: The activity screening of GL-BSA-Lut-Nps on Hepatocellular Carcinoma Bel-7402 cells was spotted by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-tetrazolium bromide (MTT) assay, cell cycle, and apoptosis were measured by flow cytometry. The solubility of GL-BSA-Lut-Nps was evaluated by ultraviolet spectrophotometer. Fluorescein isothiocyanate was employed to label the drug, and the fluorescence intensity of cells after drug uptake was detected under a fluorescence microscope to sense the targeting of GL-BSA-Lut-Nps to tumor cells. The differences of metabolites between Bel-7402 cells treated with GL-BSA-Lut-Nps and the control group were considered by 1 hydrogen-nuclear magnetic resonance metabolomics. Results: The results presented that the GL-BSA-Lut-Nps prepared by solvent removal method had good anti-tumor activity and water solubility in vitro and the No. 4 Lut nanoparticles (GL-BSA-Lut-Nps-4) screened by the MTT method had the best effect. The IC50 of the GL-BSA-Lut-Nps-4 on the Bel-7402 cell inhibition test was 1.999 ± 0.880 mg/mL. The results of cell cycle and apoptosis displayed that the anticancer effect of the prescription is more palpable. The results of the fluorescence original method are proposed to confirm that the experimentally created GL-BSA-Lut-Nps-4 have a liver targeting effect. The study of metabolomics further clarified the metabolic regulation effect of GL-BSA-Lut-Nps-4 on Bel-7402 cells. Conclusion: It delivers a theoretical basis for the development of new high-efficiency and low-toxicity traditional Chinese medicine preparations for liver cancer.

Background: Bojanggunbi-tang (BGT) is a well-known combination of ancient Korean herbal medicines and has been widely used for treating gastrointestinal symptoms. Objectives: This study was aimed at investigating whether BGT protects against non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal injury (NSI), by using a murine model of indomethacin-induced NSI. Materials and Methods: NSI was induced in the mice by subcutaneous injections of 15 mg/kg indomethacin. BGT was administered at doses of 50, 150, and 450 mg/kg, while the positive control received sodium alginate. The treatments were orally administered twice, 30 min before and 6 h after the induction of NSI. The body weight, length of small intestine, macroscopic damages, and histological damages were assessed after 24 h of induction. Results: Gross anatomical analysis revealed that BGT inhibited the shortening of the small intestine and reduced the area of ulceration. Histological analysis revealed that BGT lowered the ulceration and inflammation scores. However, there was no difference between the groups with respect to weight loss. Conclusion: BGT ameliorated NSI via its anti-inflammatory and anti-ulcerative properties. The current study suggests that BGT could be a therapeutic option for NSI.

Jan-Mar 2022, 18(77):201-206
Background: Caragana sinica (Buc'hoz) Rehd, which belongs to the legume family, is used to treat a variety of diseases such as gout, high blood pressure, neuralgia, arthritis, and eczema. Morden studies reveal that C. sinica has anti-tumor, anti-viral, anti-hypertensive, immune-stimulatory, immune-suppressive and anti-inflammatory activities. Aims: This study aims to confirm its therapeutic efficacy on contact dermatitis (CD) induced by harmful chemical. Materials and Methods: The dried roots of C. sinica were extracted using 70% ethanol, then the extract was condensed and lyophilized (ethanol extract of C. sinica, [EECS]). We investigated the effects of EECS on skin lesion severities, erythema and melanin indices, skin weights and thicknesses, histopathological changes and cytokine levels in mice with CD induced by 1-fluoro-2,4-dinitrofluorobenzene. In addition, the effects on changes in body weight and spleen body weight ratios were also investigated. Results: EECS relieved skin lesions such as roughness, abrasions, scabs, erythema, and petechia, inhibited thickening of dorsal skin and lowered erythema and melanin indexes in the CD mice. Besides, EECS reduced epidermal hyperplasia and immune cell infiltration into inflamed tissues and reduced levels of Tumor necrosis factor-α, interferon-γ, interleukin-6, and monocyte chemotactic protein-1 (MCP-1) in inflamed tissues. Finally, body weight gains and spleen/weight ratios of CD mice were unaffected by EECS, unlike dexamethasone treatment. Conclusion: These results suggest that C. sinica has potential use as a therapeutic agent for CD and the therapeutic mechanism is different from that of corticosteroids.
