ABSTRACT
<p><b>OBJECTIVE</b>To study the protective effects of salidroside on injury induced by hypoxia/hypoglycemia in cultured SH-SY5Y cell.</p><p><b>METHOD</b>Apoptosis and intracellular free calcium concentration ([Ca2+]i) were measured by flow cytometry, morphological changes and neuronal necrosis were observed with fluorescence microscope, and the lactic dehydrogenate (LDH) release was measured by LDH kits.</p><p><b>RESULT</b>Hypoxia/hypoglycemia cultures for 2 hours induced neuronal apoptosis and necrosis. They were 18.59% (P < 0.01) and 4.94% (P < 0.01) respectively. There were morphological changes including chromatin condensation, nuclear fragmentation and formed apoptotic bodies after exposed to hypoxia/hypoglycemia for 2, 4, 6, 12 hours. After 2 hours of hypoxia/hypoglycemia, neuronal [Ca2+]i and the release of LDH were significantly increased. They were 8.46 nmol/L (P < 0.01) and 16.59% (P < 0.01) respectively. The effects were enhanced with the extending time of hypoxia/hypoglycemia. Salidroside might have significantly decreased the percentage of neuronal apoptosis and necrosis, reduced neuronal [Ca2+]i and the release of LDH. The effects of salidroside were strengthened with the increasing of Salidroside dosage.</p><p><b>CONCLUSION</b>Salidroside has effect of anti-neuronal apoptosis. This effect might be related to its function of decreasing intracellular free calcium concentration.</p>
