Abstract
Moderate food intake is one of the very important reasons for enjoying a good health and ability of working. Less eating fresh vegetables may be leading to exposure to many diseases. The present investigation was carried out in an attempt to clarify the effect of the three studied vegetables namely: cabbage, carrot, radish on histological characteristics of some organs of albino rats, namely : liver, heart, spleen and brain.
The experiment included (66) males white albino rats (Sprague dawley strain) weighing between (100 and 120 gm) divided into (11) groups, every group included (6) rats. Rats were housed individually in wire cages under the normal laboratory conditions and fed on the basal diet for a week as adaptation period. Daily administrations were continued for two successive periods (6) weeks each. In the first period one group was used as control and was fed the basal diet, including casein (12.5%), corn oil (10%), vitamins mixture (1%), salt mixture (3.5%), cellulose (5%), choline chloride (0.2%) and corn starch (67.8%). While, the other ten groups were fed hyperlipidemic diet including (Basal diet supplemented by 10% animal fat excluding 10% corn oil plus 1% cholesterol).
In the second period, one group of the hyperlipidemic rats was fed on hyperlipidemic diet supplemented with different levels of the three studied vegetables (cabbage, carrot, and radish) .
Liver, heart, spleen, and brain were removed blotted on filter, immersed in (10%) neutral buffered formaline until histopathological tests were carried out.
The present investigation revealed that feeding the experimental rats with the three studied vegetables resulted in histopathological changes in liver, heart, spleen and brain tissues, due to their effects on the cholesterol fractions in the experimental rats.
