Hypolipidemic activity of a hydroalcoholic extract of Cyperus scariosus Linn. root in guinea pigs fed with a high cholesterol diet.

Lipid-lowering and antioxidant activities of a hydroalcoholic extract of Cyperus scariosus Linn. root (HCS) were evaluated in guinea pigs fed with a high cholesterol diet. Serum lipid profile (total cholesterol, triglycerides, LDL-C, VLDL-C, and HDL-C), atherogenic indices and serum enzymes (ALT, AST, ALP, LDH, and CK-MB) were performed in each group at 0 days and at the end of 60 days. Histological study of liver and kidney was done in groups 1, 2, 5, 6 and 7. The total phenolic and flavonoid content in HCS and its antioxidant activity were evaluated by the DPPH assay. Both doses of HCS decreased serum lipid profile and atherogenic indices (P < 0.05). HCS has lipid lowering, immunosuppressive and antioxidant properties, and mays have value in atherosclerosis prevention. The higher dose of HCS also reduced serum AST, ALP, and LDH levels and rosuvastatin increased AST and ALP levels (P < 0.05). Histology of the liver showed decreased lipid accumulation and improvement in hepatocytes in HCS-treated animals. The antioxidant activity of HCS may be responsible for its lipid lowering and cytoprotective action. HCS had significant lipid lowering and antioxidant activity, which; may be due to the phenolic compounds. HCS may be a safe and cost effective alternative to current statin therapy for patients with dyslipidaemia.

Evaluation of anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits.

This study investigated the possible anti-inflammatory, analgesic, and antipyretic effects of ethanolic extract of Pedalium murex Linn. fruits in selected experimental animal models. Anti-inflammatory activity of Pedalium murex Linn., with doses of 200 mg/kg and 400 mg/kg, p.o., was evaluated by Lambda-carrageenan induced paw oedema in Wistar albino rats; analgesic activity with doses of 280 mg/kg and 560 mg/kg, p.o., was evaluated by hot plate method and acetic acid induced writhing method in Swiss albino mice; and antipyretic activity with doses of 110 mg/kg and 220 mg/kg, p.o., was evaluated in New Zealand white rabbits by injecting gram -ve lipopolysaccharide obtained from E. coli. Results were analysed by one way ANOVA followed by Dunnet's multiple comparison test. Pedalium murex Linn. showed significant anti-inflammatory activity from 15 min to 180 min as compared to vehicle treated animals. It was comparable to diclofenac sodium at 180 min. The extract did not prolong the reaction time on hot plate method but significantly reduced the number of writhing after acetic acid administration. Also the extract did not show any antipyretic activity on lipopolysaccharide induced pyrexia. It is therefore concluded that the ethanolic extract of Pedalium murex Linn. fruits has an anti-inflammatory and peripheral analgesic effects.

Anti-urolithiatic effect of ethanolic extract of Pedalium murex linn. fruits on ethylene glycol-induced renal calculi.

PURPOSE: To evaluate effect of ethanolic extract of Pedalium murex Linn. fruits on experimental model of calcium oxalate nephrolithiasis. MATERIALS AND METHODS: Thirty-six male Wistar albino rats were randomly divided in 6 groups.Normal controls received distilled water for 28 days. Other five groups received ethylene glycol(1% v/v) in distilled water for 28 days. Pedalium murex ethanolic extract was given 200 mg/kg and 400 mg/kg orally in distilled water for 28 days in prophylactic groups (III and IV) and from 15th to 28th days in treatment groups (V and VI). The urea, creatinine, random blood sugar, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, bilirubin and calcium were measured on 28th day. 24 hr urinary oxalate and volume were measured on day 0 and 28. On day 28, kidneys were removed, weighed and subjected to histopathological examination. Calcium oxalate crystallization was evaluated by renal histopathology and in-vitro method of mineralization.All parameters were analyzed by Kruskal-Wallis or one-way ANOVA with post-hoc test. RESULTS: Pedalium murex showed significant improvement in renal function and kidney weight inprophylactic groups as compared to ethylene glycol controls. It did not show any effect on urinary oxalate, urine volume and any other serological parameters. Calcium oxalate crystallization was significantly reduced in all the Pedalium murex treated groups (P < .05). Calcium oxalate and phosphate mineralization were also inhibited by 33% and 57%. CONCLUSION: Ethanolic extract of Pedalium murex fruits possess significant activity for prevention of renal calculi.

Moxifloxacin-induced hypoglycemia in a non-diabetic patient.

Hypoglycemia is a rare life threatening adverse drug reaction associated with various fluoroquinolones like ciprofloxacin, gatifloxacin and levofloxacin. Moxifloxacin was considered safe in this regard. Only one case has been reported for moxifloxacin-induced hypoglycemia in a renal failure patient. Here, we are reporting the second case of hypoglycemia due to moxifloxacin without any major co-morbid condition.
