All patients were free from severe renal, hepatic, pulmonary, cardiac, metabolic and endocrinological diseases and acute infection for at least 2 weeks before surgery. Patients receiving any drug known to affect carbohydrate metabolism prior to anesthesia were excluded from the study.RESULTS Erythrocyte membrane Na+, K+-ATPase, Mg2+-ATPase, Ca2+, Mg2+-ATPase activities were not significantly changed 60min-90min after incision as compared with 30min before anesthesia, but were decreased markedly 10min and 24 hours after completion of operation (P<0.01). Plasma lipid peroxides (LPO) were increased significantly 24 hours after surgery (P<0.01) following an initially marked but transient reduction. Plasma LPO changes were not correlated with erythrocyte membrane ATPase activities, r=-0.0396, -0.0097 and 0.4383, respectively (P>0.05).CONCLUSION Abdominal surgical trauma under intravenous procaine-balanced anesthesia may be associated with the decreased ATPase activities of erythrocyte membrane and increased LPO in plasma.展开更多

The erythrocyte membrane Ca2+-ATPase activity and Na+-K+-ATPase activity were found to be decreased in the model group as compared with the control group (P<0.01, P<0.01), while no significant difference existed between the treated group and the control group (P>0.05). Our results also showed that there were more deformed red blood cells in model group than in control group under TCM and SEM (P<0.0001). No significant difference was found between control group and treated group (P>0.05). Furthermore,these findings indicated that 'Huoxuequyu' recipe , a prepared natural herbal medicine, may be involved in modulation of the activity of erythrocyte membrane enzymes,thereby protecting erythrocyte membrane, so as to improve the erythrocyte function.展开更多

Viscosity of whole blood and clinical manifestations also improved obviously. The total effective rate in lowering plasma glucose was 77. 8 % with fasting blood glucose (FBG) and 69.4 % with 2 hours postprandial plasma blood glucose (2°PBG). In the control group, viscosity of whole blood andclinical manifestations had no significant improvement. Its total effective rate in lowering plasma glucose was41. 7% with FBG and 38. 9% with 2°PBG. Conclusions: XZT played a certain role in increasing activities ofNa+ -K + -ATPase and Ca2+-Mg2+ -ATPase, decreasing viscosity of whole blood and plasma glucose and improving clinical manifestations. Therefore, XZT was experimentally manifested as an effective drug in treating NIDDM patients with Qi-Yin deficiency, renal deficiency and blood stasis.展开更多
