Effect of morin against DOCA-salt induced hypertension was evaluated by measuring blood pressure and performing biochemical estimations and histopathological examination of renal tissues.Results:DOCA-salt hypertensive rats showed considerably increased systolic and diastolic blood pressure,serum hepatic marker enzyme activities such as aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP) and gamma-glutamyl transpeptidase(GGT)and renal function markers(urea, uric acid and creatinine) in plasma. Oral administration of morin(25, 50 and 75 mg/kg bw) brought back all the above parameters to near normal level.Histopathology of kidney also confirmed the biochemical findings of this study. The effect at a dose of 50 mg/kg bw of morin was more pronounced than that of the other two doses(25 and 75 mg/kg bw).Conclusions:These findings indicate that morin exhibits strong antihypertensive effect against DOCA-salt induced hypertension.展开更多

Methods: One hundred women with singleton term pregnancy undergoing elective or emergency lower segment cesarean section under spinal anesthesia were included in this study. They were randomly allocated to receive either misoprostol 400 μ g sublingually or intravenous infusion of 20 units of oxytocin soon after delivery of the neonate. The main outcome measures were blood loss at cesarean section, change in hemoglobin levels, need for additional oxytocics and drug related side effects. Results: The mean blood loss estimatedc was significantly lower in misoprostol group compared to oxytocin group (819 ml versus 974 ml; p = 0.004). The number of women who had blood loss exceeding 500 ml and the change in hemoglobin, however,was comparable between the two groups. There was a need for additional oxytocic therapy in 16% and 18% after use of misoprostol and oxytocin respectively (p = 0.673). The incidence of side effects such as pyrexia, shivering and metallic taste was significantly higher in misoprostol group compared to oxytocin group. Conclusion: Sublingual misoprostol appears to be as effective as intravenous infusion of oxytocin in reducing blood loss at cesarean section. However, occurrence of transient side effects such as shivering and pyrexia were noted more frequently with the use of misorostol.展开更多
