The effect of propranolol on the levels of catecholamine in different parts of rat brain has been studied. The catecholamine contents of different regions were lowered by the drug. Dopamine Β-hydroxylase activity was also reduced, both

The effect of lipid lowering agents of plant origin garlic oil and guggulipid on the levels of catecholamine and dopamine Β-hydroxylase activity of normal and cholesterol fed rabbit tissues has been studied. The catecholamine levels and enzyme activity were found to be decreased in cholesterol (500 mg/kg body wt) fed animals. The feeding of garlic oil (5 mg/kg body wt) and guggulipid (100 mg/kg body wt) an exudate of

The effect of lipid lowering agent, guggulsterone, the purified fraction of guggulipid, on biogenic monoamine levels and dopamine

The levels of lipoprotein-X in circulation increased with chronic administration of ethanol or acetaldehyde. A similar profile was seen in rat serum with alkaline phosphatase activity and bilirubin content. Total cholesterol, phospholipids and triglyceride contents increased followed by a decrease by progressive feeding with ethanol or acetaldehyde. The effect of acetaldehyde was more pronounced than that of ethanol.

The levels of lipid peroxides in circulatory lipoproteins increased with chronic administration of ethanol or acetaldehyde. Low density lipoprotein showed a greater increase in its content of lipid peroxides than very low density lipoprotein or high density lipoprotein. However, very low density lipoprotein was more prone to lipid peroxidation

Chronic administration of ethanol in rats caused the reduction of serum cholesterol binding reserve. The very low density and high density lipoproteins, main serum cholesterol binding reserves, were slightly increased with corresponding increases in their lipid and protein components during initial stage of alcohol consumption. However, these capacities get deminished during reversal of hyperlipemia induced by prolonged action of ethanol. This situation may be an early indicator for the initiation of hepatic damage and a variety of secondary effects of ethanol.

Modification of low density lipoprotein by nonenzymic glycosylation resulted in decreased receptor-mediated lipoprotein catabolism. Guggulsterone treatment caused significant increase in binding of [125I] low density lipoprotein as well as [125I] glycosylated low density lipoprotein. Scatchard plot analysis of the binding activity revealed that under the influence of guggulsterone, the liver membrane contains increased amounts of a functional lipoprotein receptor that binds more low density lipoprotein particles.
