Abstract

1. 1. Quails hatched from eggs incubated at physiological temperature (37.5°C—normal quails) and elevated (39.3°C—warm quails) were injected with l -thyroxine (T4) at dose 600 μg per kg of body wt, every 48 hr for 17 days. 2. 2. After last injection of hormone the total protein level in the blood plasmaa as well as activities of the following enzymes in liver homogenates were detemined: phosphoglucomutase (PGM), glucosephosphate isomerase (GPI), phosphofructokinase (PFK), aldolase (ALD) and lactate dehydrogenase (LDH). 3. 3. The total protein level in the blood plasma was lowered in quails injected with l -thyroxine. Simultaneously, significant increase of the activity of PGM, GPI and PFK was observed. 4. 4. The activity of these enzymes increased up to 138.4;181.0 and 290% of the control in warm quails and 142.1;175.3 and 137.5% of the control in normal quails, respectively. 5. 5. The activity of lactate dehydrogenase in T4-treated quails changed slightly, while the activity of aldolase lowered below the control activity in normal quails and increased up to 163.7% of the control in T4-treated warm quails.
