: To investigate the effects of cyclosporine A on renal ischemia-reperfusion injury during transient hyperglycemia in rats.
: In a model of ischemia-reperfusion-induced renal injury and transiently induced hyperglycemia by intraperitoneal injection of glucose, 2.5 g.kg-1, Wistar rats were anesthetized with either isoflurane or propofol and received intravenous cyclosporine A, 5 mg.kg-1, five minutes before reperfusion. Comparison groups were isoflurane and propofol sham groups and isoflurane and propofol ischemia-reperfusion-induced renal injury. Renal tubular cell viability was quantitatively assessed by flow cytometry after cell culture and classified as early apoptosis, necrotic cells, and intact cells.
: Early apoptosis was significantly higher in isoflurane and propofol anesthetized animals subjected to renal ischemia-reperfusion injury when compared to both cyclosporine A treated and sham groups. Necrosis percentage was significantly higher in propofol-anesthetized animals subjected to renal ischemia-reperfusion injury. The percentage of intact cells was lower in both, isoflurane and propofol anesthetized animals subjected to renal ischemia-reperfusion injury.
: In a model of ischemia-reperfusion-induced renal injury, cyclosporine A, 5 m.kg-1, administered five minutes before renal reperfusion in rats with acute-induced hyperglycemia under either isoflurano or propofol anesthesia, attenuated early apoptosis and preserved viability in renal tubular cells, regardless of the anesthetic used.
研究环孢素A对大鼠短暂高血糖期间肾缺血再灌注损伤的影响。
在通过腹腔注射2.5 g·kg-1葡萄糖诱导缺血再灌注性肾损伤和短暂高血糖的模型中，用异氟烷或丙泊酚麻醉Wistar大鼠，并在再灌注前5分钟静脉注射5 mg·kg-1环孢素A。比较组为异氟烷和丙泊酚假手术组以及异氟烷和丙泊酚缺血再灌注诱导的肾损伤组。细胞培养后通过流式细胞术定量评估肾小管细胞活力，并分为早期凋亡细胞、坏死细胞和完整细胞。
与环孢素A治疗组和假手术组相比，接受肾缺血再灌注损伤的异氟烷和丙泊酚麻醉动物的早期凋亡明显更高。接受肾缺血再灌注损伤的丙泊酚麻醉动物的坏死百分比明显更高。接受肾缺血再灌注损伤的异氟烷和丙泊酚麻醉动物的完整细胞百分比均较低。
在缺血再灌注诱导的肾损伤模型中，在异氟烷或丙泊酚麻醉下急性诱导高血糖的大鼠肾再灌注前5分钟给予5 mg·kg-1环孢素A，可减轻早期凋亡并保留肾小管细胞的活力，与所使用的麻醉剂无关。
