The histology of the adrenals of the mongooseHerpestes edwardsii edwardsii has been studied. Three layers in the cortex, namely zona giomerulosa, zona fasciculata and zona reticularis and central medulla surrounded by the cortex have been observed.
Employing histochemical techniques it was revealed that the cortex is rich in glycoproteins, lipids and protein bound Amino groups. It has moderate amounts of proteins containing sulphydril and disulphide radicals and tyrosine. Tryptophan has not been detected.
Negligible amounts of mucopolysaccharides were detected in the medulla. Aspects dealing with the occurrence of carbohydrates, proteins and lipids in various regions of the cortex are discussed.
