Abstract
Effects of garlic on hypocholesterolemia, anticoagulation and hypoglycemia were studied in the present experiments using male rats. The results were summarized as follows. 1. The supplementation of $2{\sim}4%$ garlic to 2% cholesterol diets did not affect food intake and weight gain in male rats. 2. Rat's groups fed the diets supplemented with $2{\sim}3%$ garlic (C.D.E.F) to 2% cholesterol diet (B) decreased serum total cholesterol levels by $16{\sim}32%$, triglyceride levels by $18.6{\sim}26.8%$ and ${\beta}/{\alpha}-lipoportein$ rations by $42{\sim}58%$, but increased HDL-cholesterol levels by $29{\sim}65%$ as compared to B group, and so the author assumes that garlic supplementation exerts hypocholesterolemic effect on cholesterol - fed rats because of the increase of HDL and HDL - cholesterol levels. 3. Rat's groups fed the diets supplemented with $2{\sim}4%$ garlic (C.D.E.F) to 2% cholesterol plus 0.25% bile salt diet (B) increased whole blood coagulation times, prothrombin times and fibrinolytic activities, but decreased plasma fibrinogen levels as compared to B group, and so the author assumes that garlic supplementation exerts anticoagulative effect because of the inhibition of fibrinogen synthesis in male rat's liver. 4. Rat's groups fed the diets supplemented with $2{\sim}4%$ garlic (B.C.D.E) to standard diet (A) decreased serum glucose levels by $1{\sim}24%$, but increased serum insulin concentrations by $0.5{\sim}3.0$ times as compared to A group, and so the author assumes that garlic supplementation exerts hypoglycemic effect because of the increase of serum insulin levels by stimulation pancreatic secretion of insulin from ${\beta}-cells$ in the islets of Langerhans.
