Abstract

This research was conducted to evaluate cardiovascular disease caused by atherogenic diets, based on immunological assay by measuring the concentration of lipoprotein (a)/Lp (a). Eighty male Sprague Dawley rats, 150-200 grams' of body weight and three months of age were used in this research. The rats were randomly alloted into four groups, 20 of each. Group I as control was fed normal diet, group 11 was fed diet containing high cholesterol, group 111 was fed diet containing high fat and group 117 was fed diet containing high cholesterol and high fat (atherogenic). After 2, 4, 8, 16 weeks on experimental diet, 20 rats were selected randomly (5 rats of each group), and blood sample were withdrawn for Lp (a) analysis. All animal were then killed and the heart were taken out for histopathological analysis. The statistical analysis for Lp (a), data showed that there were significant differences (p<0.05) among all of the treatments, high fat diet had the greatest influence on Lp (a) concentration. It can be concluded that Lp (aconcentration could be influence by high fat diet, but not by period of treatment. Lp (a) concentration seems connected with the incidence of atherosclerosis in rats. For this reason, evaluation of Lp (a) concentration could be considered as a routine procedure in general health evaluation.

Abstract

We have investigated the Bowman's gland of the nasal cavity after in vivo study in the Sprague-Dawley rats to asses its biomarker potential in vitamin A nutritional study. Fourty-eight male weanling SpragueDawley rats at 3-4 weeks of age were allotted to four groups of 12 each and were fed diets either vitamin A-deficient or supplemented with 30.000 IU vitamin A/kg for 150 days. Rats in their respective groups were also given fume of vehicle for 150 days. Fumigation was done 2x/day for 1 hour each. Rats given vitamin A-deficient diet and fume of vehicle had the most extensive inhibition of glycoprotein synthesis in cells of Bowman's gland in the olfactory region of the nasal cavities as determined by severe loss of Alcian blue-periodic acid-Schiff staining material. Histochemical lesions were not seen in nasal cavity of vitamin A-supplemented rats

Abstract

Thirty male rats, strain Sprague Dawley were used as experimental animal to study the role of intrinsic (mitochondrial) pathway apoptosis in atherogenesis due to high fat and high cholesterol diet. The rats were randomly alloted into three group (I, II, III) of 15 each. Group I as control was fed normal diet, group II was fed diet containing high fat diet, and group III was fed containing high fat and high cholesterol diet (atherogenic diet). After 6 and 12 weeks on experimental diet, 15 rats were selected randomly (5 rats of each group). All animal were then killed and the aorta were taken out for caspase-9 immunohistochemical analysis. Based on the present study result it can be concluded that high fat diet and high cholesterol diet could induced apoptosis through caspase-9.
