Antihypertensive and cardioprotective effects of the Lagenaria siceraria fruit in NG-nitro-L-arginine methyl ester (L-NAME) induced hypertensive rats.
    Pharmaceutical biology, 2012, Volume: 50, Issue:11

    Lagenaria siceraria (Molina) Standl. (Cucurbitacae) (LS) has been reported to possess cardioprotective, antihyperlipidemic, and diuretic activities.. To evaluate antihypertensive and cardioprotective effects of the Lagenaria siceraria fruit powder in N(G)-nitro-L-arginine methyl ester (L-NAME) induced hypertension in rats.. Male Wistar rats were divided in four groups. Control 2% gum acacia p.o., L-NAME (40 mg/kg p.o.), LS (500 mg/kg p.o.) + L-NAME (40 mg/kg p.o.), L-arginine (100 mg/kg p.o.) + L-NAME (40 mg/kg p.o.). Treatment period was 4 weeks. On day 29 serum marker enzymes, cholesterol and heamodynamic parameters were measured. Histology of heart was performed. LS powder was characterized by HPLC.. Systolic blood pressures were increased by L-NAME (p < 0.001). In both drug treated groups systolic and diastolic blood pressures were reduced significantly (p < 0.001) compared to L-NAME. In L-NAME group significantly (p < 0.01) elevated cholesterol which was reduced (p < 0.05) by LS treatment. In L-NAME group inflammation and necrosis (0-35%) was present in heart whereas there was no change in myocardium of LS and L-arginine treated rats. Vitexin, orientin and isoorientin were detected in methanol extract of LS powder.. L-NAME induced hypertension in rats was reduced by treatment with LS. The absence of necrosis, inflammation in the heart and significant reduction in serum cholesterol in LS and L-arginine treated rats indicated cardioprotective activity. Antioxidant activity of orientin and isoorientin appears to reduce the L-NAME induced damage. It is concluded that LS fruit possess antihypertensive and cardioprotective activity.
