Abstract
Summary
Examination of 10 different inbred strains and 2 hybrids of mice indicated that the normal levels of amylase activity vary from one strain to another. Further, the activity of the enzyme in the salivary gland tissue is markedly altered by gonadectomy. The effect of such endocrinological imbalancing varies with each strain. In some strains enzyme activity remains unchanged. In some, activity increases while in others it decreases. The pattern of change was not always the same for females as for males of the same strain. In other words, we are dealing with an enzyme system which is related to the genotype, but which may be influenced in an undetermined fashion by endocrine manipulation.
