The effect was studied of dry leaf extract of Serratula centauroides L. on the behavior of white rats (Wistar) in tests with positive reinforcement. It was revealed that the extract of S. centauroides at doses of 50200 mg/kg promotes in animals a decrease in the level of anxiety, adaptation to unfamiliar conditions, and as a consequence, to an increase in the volume of food intake. And also a more rapid formation of a conditioned reflex with positive reinforcement. In animals treated with S. centauroides extract, the volume of food taken in hypophagia test was 1.42.7 times higher than the control value. In the T-shaped maze, 5080% of the animals in the experimental groups developed a conditioned reflex to positive reinforcement, while none of the animals in the control group reached the learning criterion. The S. centauroides extract showed the most pronounced effect on the behavior of animals in tests with positive reinforcement at a dose of 100 mg/kg.

Abstract High blood cholesterol is often called hypercholesterolemia is a risk factor for the emergence of pathological conditions such as heart and blood vessel disease. Hypercholesterolemia has an important role in the occurrence of damage to the endothelial cells is mainly caused by oxidized LDL. Oxidation of LDL triggers the formation of TNF - ?. Leaves messengers that allegedly contains flavonoids can improve the situation of hypercholesterolemia through the barriers specifically the expression of TNF - ? increased due to hypercholesterolemia. Plants messengers known to contain alkaloids, flavonoids, tannins, saponins, polyphenols, calcium oxalate, fats, and essential oil. Flavonoids which has the ability to bind the atom to form free radicals not to excess free radicals, thereby inhibiting the oxidative modification of LDL become ox-LDL so it will not be formed atherosclerosis. This study uses the Randomize pattern Pre and Post Test Control Group Design, using white rats (Rattusnovergicus) with Wistar strain aged 3-4 months, weighing 175-200 grams. Divided into four groups: Group I as a control with placebo, Group II treatment using extracts of ethanol leaves a messenger at a concentration of 10%, Group III treatments using extracts of ethanol leaves a messenger at a concentration of 20%, Group IV is to use the extract ethanol leaves errand at a concentration of 30%. It can be concluded at 4 dose group 30% messengers leaf extract significantly different, p <0.05, so it can be said that the provision of effective messengers extract at a dose of 30%.

Dyslipidemia is a coronary heart disease risk factor. Dyslipidemia is characterized by the elevated levels of LDL, triglycerides, total cholesterol, and the decrease in HDL. Ginger rhizome (Curcuma xanthorriza Roxb.) and bay leaf (Eugenia polyantha Wight.) are local plants that have the abilities to decrease total cholesterol. This research design was true experimental with pre- and post-control group design. Criteria of sample were white rats, wistar strain, male, age of 8-12 weeks, and body weight range of 150-200 grams. Sampling method was simple random sampling. The experimental rats were acclimatized for seven days. Hypercholesterol diet was fed two weeks, and then the rats were given intervention and get hypercholesterol diet for two weeks. During intervention, the experimental rats were divided into 6 groups of administrationi.e, rats administered with 1) carboxymethil celluse/CMC, 2) simvastatin 0,9 mg/kg BW/day, 3) ginger rhizome extract 200 mg /kg BW/day, 4) ginger rhizome extract 400 mg/kg BW/day, 5) bay leaf extract 200 mg/kg BW/day, and 6) bay leaf extract 400 mg/kg BW/day. Blood samples were taken from caudal vein and total cholesterol levels were measured by spectrophotometry. The analysis used paired T test, One Way ANOVA test. The results showed ginger rhizome extract did not effectively reduce total cholesterol. However, bay leaf extract effectively decreased total cholesterol levels with the highest total cholesterol reduction was found in rats administered with dose of 400 mg/kg BW/day i.e, 15.4 mg/dl. Bay leaf extract have the same effectivity with simvastatin as a standard drug in lowering cholesterol level.
