Histochemical variations of the lipids of the adrenals in guinea pigs with experimental asthma

With the histochemical methods for the total lipids, cholesterol and its esters, the fatty acids and the plasmal reaction, and vitamin C, we have studied their variations of intensity in the adrenal glands of forty-six guinea pigs. In the adrenal glands of most of the control animals all these reactions were of great or medium intensity, but decreased considerably in intensity in the adrenals of nearly all the ten guinea pigs shocked with formol. In the glands of 50 per cent of the ten animals with experimental asthma the intensity of reaction for the total lipids was slightly decreased. The reactions for cholesterol and its esters also suffered a slight decrease of intensity in the adrenal glands of 30 per cent and 70 per cent of this group of asthmatic guinea pigs. The reaction for vitamin C did not show any variation.
