[Effect of rations with a varying content of polyunsaturated fatty acids and vitamins on the state of the small intestine in respect of age].
Groups of young sexually mature and old albino rats were kept for three months on 4 isocaloric rations, viz. balanced, with reduced proportion of essential fatty acids or group 'B' vitamins and with simultaneous curtailment of fatty acids and vitamins. With vitamin deficiency there was a certain derangement in the structure and function of the small intestine, especially in older animals. A shortage of essential fatty acids impaired the condition of the small intestine only in old animals. In cases of concurrent deficiency of vitamins and essential fatty acids maximal changes in both young and old animals were in evidence.
