Effect of essential oil of onion and garlic on experimental atherosclerosis in rabbits.

The effects of the essential oils of onion (extracted from 2 g of raw onion per kg body weight) and garlic (extracted from 1 g of raw garlic per kg body weight) have been observed on experimental atherosclerosis produced by cholesterol feeding (0.5 g/kg) in rabbits. The rise in serum cholesterol and serum triglycerides was significantly reduced by both onion and garlic during the 4-month period of study. Cholesterol feeding significantly increased beta-(P less than 0.01) and pre-beta (P less than 0.001) lipoproteins while decreasing the alpha-fraction (P less than 0.001). Onion and garlic both prevented these changes. The beta/alpha ratio, which was initially 1.6 : 1, rose to 4.5 : 1 and 5.7 : 1 at the end of 2 months and 4 months of cholesterol feeding. However, this ratio did not increase significantly, both at the 2-month and 4-month period, when onion and garlic were added. Fibrinolytic activity significantly increased with onion (P less than 0.001) and garlic (P less than 0.001) while feeding only cholesterol actually decreased it (P less than 0.001). Onion and garlic reducec aortic atheroma by about half. It is suggested that the essential oils of onion and garlic protect against experimental atherosclerosis by preventing the fall in the alpha lipoprotein fraction and by enhancing fibrinolytic activity, as well as by lowering the serum cholesterol and triglyceride levels.

The protective action of essential oils of onion and garlic in cholesterol-fed rabbits.

The effects of the essential oils of onion and garlic have been investigated in cholesterol-fed rabbits and have been compared with the effects of clofibrate. The marked rise in serum cholesterol and blood coagulability that followed 3 months of cholesterol feeding (0.2 g/kg/day) was significantly reduced by the essential oils of both onion and garlic. Fibrinolytic activity was actually increased even above the normal control levels. The essential oils of onion and garlic (equivalent to 1 g/kg/day of raw bulbs) proved more effective than clofibrate in the usual clinical dose of 33 mg/kg/day. Garlic was even more effective than onion. Cholesterol feeding increased the average lipid content of aorta from 5.95 to 13.75 mg/100 mg dry weight. With addition of clofibrate, onion or garlic the values were 7.79, 6.23 and 5.28 mg/100 ml, respectively. Thus it can be seen that the essential oils effectively prevent lipid acculation in the rabbit oarta.

A correlative study of seminal biochemistry and testicular histology in infertile males.

Two androgen-dependent constituents of the seminal plasma, fructose and acid phosphatase, have been estimated in 50 infertile males along with a testicular biopsy. Azoospermics, as a group, showed a very wide range of fructose (16-600 mg%) as compared to 210-397 mg% in healthy fertile males. Oligospermics tended to have low values with a mean of 218 +/- 75.1 mg%. Acid phosphatase in the controls was 1927 +/- 164.6 K.A. unit/ml and was generally higher in the infertile groups. The state of spermatogenesis, as revealed by testicular biopsy, bore no consistent relationship with the seminal fructose or acid phosphatase. It appears that there may be no inter-relationship between the activity of the germinal epithelium and the secretion of the accessory glands and, although both are androgen-dependent, they can be affected separately by a multitude of factors in human infertility.
