Movements of field mice Apodemus agrarius (Pallas) in a suburban mosaic of habitats.

Movements of field mice (Apodemus agrarius) were studied using snap traps and coloured bait. The presence of coloured bait was recorded in 35% of field mice captured. Of animals with coloured bait, 60% had moved further than 100 m.

Evaluation of the influence of epoxide resins and their hardeners on the female body. II. Biochemical studies.

In women employed in an industrial plant in direct contact with epoxide resins and their hardeners, the following biochemical parameters were determined in blood: total protein, seromucoid, haptoglobin, hemoglobin variants, methemoglobin, alpha1-inhibitor of trypsin, lactate dehydrogenase, aspartate and alanine aminotransferases, alkaline and acid phosphatase, gamma-glutamyl transpeptidase, leucylaminopeptidase, and alanine aminopeptidase. Depending on duration of work, Hb A2 fraction and lactate dehydrogenase increased significantly, and aspartate aminotransferase, acid and alkaline phosphatase activities decreased. In pregnant women, leucylaminopeptidase activity and isozyme of placental alkaline phosphatase were decreased.

Evaluation of the influence of epoxide resins and their hardeners on the female body. I. Skin tests.

Skin tests of hypersensitivity were performed in 175 women and 16 men having direct contact during work with epoxide resinsand their hardeners. The tests were applied for 24 hours, and results were recorded after 24, 48 and 72 hours. The percentages of positive skin tests and numbers of skin lesions were found to increase with time of employment in contact with epoxide resins and their hardeners.

Influence of industrial toxic compounds on pregnancy. VI. Some tissue enzymes in pregnant guinea pigs exposed to the action of triethylenetetramine.

Gamma-glutamyl transpeptidase activity in kidney homogenates, aspartate and alanine aminotransferase activities in liver homogenates, and cholinesterase activity in brain homogenates were determined in nonpregnant and pregnant guinea pigs exposed to absorption through the skin of the epoxy resin triethylenetetramine. Elevated activity of gamma-glutamyl transpeptidase in the kidneys of pregnant animals, and aspartate aminotransferase in the liver of nonpregnant guinea pigs were observed.
