Effects Of Yoyo Bitters And Swedish Bitters On The Arylesterase Activity In Very Low Density Lipoprotein Of Male Albino Rats

In order to investigate the effects of Yoyo and Swedish bitters on arylesterase activity in very low density lipoprotein (VLDL), 40 male albino rats were divided into 6 groups; i, 3-week Yoyo bitters. ii, 3-week Swedish bitters. iii, 3-week control. iv, 6-week Yoyo bitters. v, 6-week Swedish bitters, vi, 6-week control. Daily weight of animals were determined and dosage of bitters corresponding to weight of each animal was administered. VLDL was isolated by a simple precipitation procedure and Arylesterase activity was determined. There was no significant difference in the effect of both Yoyo and Swedish bitters on arylesterase activity (P>0.05) as compared with the control suggesting that neither bitters affect the VLDL arylesterase activity,. However, there was an increase in the activity of arylesterase (P<0.05) in the entire 6-week groups compared to the 3-week groups suggesting that increase in age might increase VLDL arylesterase activity which is an antioxidant.
