Figure 5: Effect of Ecklonia cava polyphenols on intraneural accumulation of sorbitol in the sciatic nerves of diabetic animals. Sorbitol concentration in the nerve homogenates was estimated by analytical high-performance liquid chromatography employing a gradient program of mobile phase (CH3CN and H2O) with a flow of 1.0 mL/min against a standard sorbitol solution (100 μg/mL). Sorbitol concentration was determined by quantifying the area under the curve of sorbitol peak. Values are expressed as mean ± standard error of the mean (n = 6). ***P < 0.001 compared with normal controls, ###P < 0.001 compared with diabetic peripheral neuropathy control |
