Dietary hexachlorocyclohexane (HCH) and gamma-isomer of HCH produced significant increase in liver weights of mice. Elevated levels of alanine and aspartate aminotransferases and of alkaline phosphatase in the blood of these animals suggested hepatotoxicity. Hepatic soluble enzymes--aspartate aminotransferase and lactate dehydrogenase--were markedly lowered. Among the hepatic lysosomal enzymes, acid phosphatase and acid cathepsin were increased in the experimental animals. Hepatic glucose-6-phosphatase was lowered by HCH while aldolase activity was increased. Hydrolytic enzymes in small intestine, viz., disaccharidases, lipase, amylase, dipeptidase and phosphatases, were also affected by dietary HCH and gamma-HCH. The results suggested cellular toxicity in hepatocytes of HCH and gamma-HCH fed animals, and also interference in gastrointestinal absorption.

Interspecific F1 hybrids of Peromyscus maniculatus (deermice) and P. polionotus (oldfield mice) were backcrossed to P. maniculatus. Backcross progeny were electrophoretically typed for 11 variant protein markers: albumin, transferrin, leucine aminopeptidase, amylase, 6-phosphogluconate dehydrogenase, nucleoside phosphorylase, dipeptidase, tripeptidase, glutamate oxaloacetate transaminase, alcohol dehydrogenase, and sorbitol dehydrogenase. Genetic variation for each protein was attributed to a single autosomal locus. The alcohol dehydrogenase (Adh), salivary amylase (Amy), and albumin (Alb) loci appeared to be linked in the sequence of Adh-11.5 cM-Amy-33.3 cM-Alb. The tripeptidase locus, Pep-2, also may be loosely linked to Alb in this group. Variants at all other loci assorted independently. These and other known linkage relationships in Peromyscus correspond closely to those of the house mouse, Mus musculus. The available evidence in Peromyscus further supports the concept of linkage conservation by natural selection.
