Abstract

We investigated the antihypercholesterolemic effects of traditional Japanese herbal medicine Dai-saiko-to (Da-Chai-Hu-Tang in Chinese) in female heritable Kurosawa and Kusanagi-hypercholesterolemic (KHC) rabbits. The plasma total cholesterol levels increased for up to 12 weeks after beginning a diet containing 0.1% cholesterol then reached a plateau of about 603 mg dl(-1). Dai-saiko-to was administered at doses of 0.5-1.0 g kg(-1) per day or pravastatin 10 mg kg(-1) per day for 24 weeks. Plasma total cholesterol levels were significantly decreased in the groups administered Dai-saiko-to 1.0 g kg(-1) per day or pravastatin for 4-24 weeks, whereas there were no change with plasma phospholipid and triglyceride levels. However, Dai-saiko-to 1.0 g kg(-1) per day significantly decreased plasma LDL cholesterol levels, but had no effect on either VLDL- or HDL-cholesterol levels. Moreover, LDL-receptor mRNA levels in the liver were significantly increased in the Dai-saiko-to 1.0 g kg(-1) per day group compared with those of animals receiving the 0.1% cholesterol diet. In addition, both groups receiving Dai-saiko-to 1.0 g kg(-1) per day and pravastatin showed a significantly reduced percentage of intimal surface area of thoracic aorta in...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
