ABSTRACT
<p><b>OBJECTIVE</b>To study the analgesic, antipyretic and anti-inflammatory effect of Bailian Caogen granule.</p><p><b>METHOD</b>The antipyretic effects of Bailian Caogen granule was evaluated in rabbit fever model induced by peptone. The analgesic effect of the drug was studied with pain model of mice induced by acetic acid and hot plate, The severity of oedema in inflamed animal was observed to study the anti-inflammatory effects of Bailian Caogen granule.</p><p><b>RESULT</b>Bailian Caogen granule could obviously inhibit the fever of rabbits. The number of writhing induced by acetic acid was reduced and the pain threshold of mice was increased by Bailian Caogen granule. Bailian Caogen granule also had anti-inflammatory activity against xylene-induced mouse ear swelling and carrageenin-induced rat paw edema.</p><p><b>CONCLUSION</b>Bailian Caogen granule has significant analgesic, antipyretic and anti-inflammatory activities.</p>

<p><b>OBJECTIVE</b>To study the protective effect of Ginkgo biloba extract(EGb) on the kidney in the case of ischemia-reperfusion injury.</p><p><b>METHOD</b>The model of renal ischemia-reperfusion injury in male rats was made by ligation of left renal artery for 45 min and 4 h of reperfusion. The rats with pretreament were fed with EGb prior to operation. The change of MDA, SOD, Na+-K+-ATPase, Ca2+-ATPase in kidney and BUN, Cr in plasma were determined. The renal pathologic changes were observed.</p><p><b>RESULT</b>After ischemia-reperfusion, the content of MDA in renal cortex and the levels of BUN, Cr in plasma were increased,the activity of SOD,Na+-K+-ATPase, Ca2+-ATPase in renal cortex were decreased, and the phathological changes induced by ischemia-reperfusion in renal tissues were observed clearly. The pretreatment of rats with EGb coued significantly prevente the reduction of SOD, Na+-K+-ATPase, Ca2+-ATPase activity in renal cortex and the increase of MDA content in renal cortex, decrease the concenration of BUN, Cr in plasma. The pathological changes of proximal tubular cells in rats kidneys induced by ischemia-reperfusion were also prevented by the pretreatment with EGb.</p><p><b>CONCLUSION</b>EGb can protect rats from renal injuries caused by ischemia-reperfusion.</p>
