✦ Synopsis

Studies on the activity of aldolase, aspartate aminotransferase and on the level of glucose in the blood serum of chickens from various breeds and crossbreds have shown that: 1. Breed and sex had a significant influence on the level of glucose and the activity of aldolase and aspartate aminotransferase. 2. The highest level of glucose was observed in both sexes of White Rock chickens; the lowest in Greenleg hens and Leghorn cocks. 3. The highest activity of aldolase was observed in White Rock cocks and Plymouth Rock hens; the lowest in Greenleg hens and Leghorn cocks. 4. The highest activity of aspartate aminotransferase was observed in White Rock chickens; the lowest in Leghorns. 5. As regards the traits investigated, crossbreds, in comparison to the parental breeds, were characterised in a majority of cases by values intermediate or only slightly different. Cases of homosis and heterosis in the level of the physiological indicators examined were also observed.

Differences in reaction to exogenous insulin and adrenalin were studied among chickens of 'Leghorn', 'White Rock' and 'Rhode Island Red' breeds, using level of blood glucose as indicator of the reaction to hormones. It was found that: 1.) The physiological quantity of glucose in blood in chickens of

To assess the severity of ischemic liver injury, we examined release of mitochondrial aspartate aminotransferase (EC 2.6.1.1) and its cytoplasmic isozyme from the ischemic rat liver into the circulation. Their patterns of leakage were quite different: the level of cytoplasmic aspartate aminotransfer

The effect of potassium depolarization and N-methyl-D-aspartate (NMDA) on the activity of aspartate aminotransferase (AAT; EC 2.6.1.1), an enzyme suggested to be involved in neurotransmitter glutamate synthesis, was studied in cultured cerebellar granule neurons. Both KCI and NMDA increased AAT acti
