Effect of allyl glycoside extracted from Herba Rhodiolae on activity and proliferation of cultured Schwann cells under high glucose condition / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe changes in activity and proliferation of cultured Schwann cells under the high glucose condition and effect of allyl glycoside extracted from Herba Rhodiolae (AG) on these changes for exploring the possible mechanism of diabetic peripheral nerve injury and the pharmacologic action of AG on them.</p><p><b>METHODS</b>Adopting refined Brokes method, Schwann cells were isolated from the sciatic nerve tissue of newborn Wistar rats and purified. Their activity and proliferative capability were determined using XTT method and 3H-TdR incorporative method respectively.</p><p><b>RESULTS</b>High glucose showed marked inhibitory effect on both activity and proliferative capability of Schwann cells, and the inhibition could be markedly improved by AG.</p><p><b>CONCLUSION</b>Diabetic peripheral nerve injury is possibly related to inhibitory effect of high glucose on activity and proliferative capability of Schwann cells. Effect of AG in improving these inhibitory changes provides the experiment basis for clinical use of traditional Chinese medicine, Herba Rhodiolae.</p>
