Effect of Yucca schidigera extract on blood pressure, antioxidant activity and some blood parameters in the L-name-induced hypertensive rats

Öz:
Bu çalışmada, L-NAME ile hipertansiyon oluşturulmuş sıçanlarda diyete Yucca schidigera ekstraktı (YSE) ilavesinin kan basıncı, antioksidan aktivite (AA) ve bazı biyokimyasal parametreler üzerine etkileri araştırıldı. Araştırmada, 18 adet erkek Sprague-Dawley sıçan kullanıldı ve sıçanlar; 1) standart diyetle adlibutum beslenen kontrol grubu, 2) içme sularına günde 75 mg/L N-nitro-L-arginine methyl ester (L-NAME) uygulanan grup ve 3) içme sularında L-NAME alan grubun diyetine 125 ppm YSE uygulanan grup olmak üzere her biri 6 sıçandan oluşan üç gruba ayrıldı. Araştırma 4 hafta sonra sonlandırıldı. L-NAME uygulanan sıçanlarda ortalama arteriyel kan basıncı (OAKB) kontrol ve YSE+L-NAME gruplarına göre yüksek çıktı. Kalp atım sayısı ise YSE+L-NAME uygulanan sıçanlarda kontrol ve L-NAME grubuna göre düşük belirlendi. L-NAME uygulaması NO metabolitleri (NOx) ile vitamin A düzeyini azaltırken, β-karoten ve methemoglobin değerlerini artırdı. Sonuç olarak, L-NAME ile hipertansiyon oluşturulmuş sıçanların diyetine YSE ilavesinin NO oluşumunu artırarak ortalama arteriyel kan basıncını düzenleyebileceği düşünülmektedir.

L-NAME ile hipertansiyon oluşturulmuş sıçanlarda diyete Yucca schidigera ekstraktı (YSE) ilavesinin kan basıncı, antioksidan aktivite ve bazı biyokimyasal parametreler üzerine etkisi

Öz:
The present study was aimed at investigating the effects of dietary supplementation of Yucca schidigera extract (YSE) on blood pressure, antioxidant activity and some biochemical parameters in the L-NAME-induced hypertensive rats. The study was performed on eighteen male Sprague-Dawley rats divided into 3 groups with 6 animals per group: 1) Control, fed standard chow ad libitum, 2) N-nitro-L-arginine methyl ester (L-NAME)-treated group, 75 mg/L drinking water, 3) YSE+L-NAME group, YSE (125 mg/kg diet)+L-NAME (75 mg/L drinking water), through study period lasted at 4 weeks. L-NAME-treated rats had significantly (P<0.05) higher the mean arterial blood pressure (MABP) as compared with the rats in the control and YSE+L-NAME groups. L-NAME+YSE-treated rats had lower heart rate (HR) as compared to the L-NAME-treated and control rats and, higher MABP as compared to the control rats. Plasma concentration of NO metabolites (NOx) decreased after treatment with L-NAME. LNAME+ YSE-treatment increased the plasma malondialdehyde (MDA) and NOx concentration but decreased the antioxidant activity (AA), glucose, total cholesterol and total protein levels as compared to the other groups. The L-NAME-treatment decreased the vitamin A, but increased the beta-carotene and methemoglobin concentrations as compared to the other groups. In conclusion, these results may suggest that YSE ameliorates the increase of MABP in the L-NAME-induced hypertension by enhanced generation of vascular NO.
