As a micronutrient, selenium has high biological activity in the form of selenium methionine and selenium cysteine, and it is identified in the structure of functionally important selenoproteins, such as glutathione peroxidase and iodothyronine dehydrogenase. Insufficient supply in foods causes the ...

In acute experiments on rabbits, hydrocortisone administration modulated the increase in action potentials generated in the small intestine in response to electrical stimulation.

Structure and rate of development of the exocrine and endocrine sections of the pancreas in the developing rat foetus were studied using electron microscopy. In the foetus at 16 to 20 days old there was uneven development of the glandular tissues of the pancreas, with the islet apparatus...

Hydroxythiamin, given parenterally to male rats, body weight 160 to 180 g, at 400 mg/kg body weight, induced, during the 1 to 6 h after, an increase in the concentration of 11-hydroxycorticosteroids in blood without altering the concentration in adrenals. After 12 h the concentration of...

In rats 2 and 6 months old irradiated with γ-rays, there were decreases in VLDL and LDL cholesterol and in triacylglycerol concentrations in serum after 24 h of exposure.

Rats were given daily by mouth for 16 days ¹³⁷Cs 20 kBq or a single intramuscular dose of ₁₃₁I 500 kBq or both together. 6 months after the last treatment, the rats were killed and lipids were estimated in liver, digestive tract and muscle. ¹³⁷Cs increased concentration of total lipids in muscle...

In 263 irradiated rats, cholesterol esterification in blood was decreased and remained low 7 months after irradiation. This may have been due to impairment of protein synthesis in hepatocytes caused by irradiation. In hepatocytes of irradiated rats, considerable reorganization of chromatin...

Male rats developed atherogenic dyslipoproteinaemia 10 to 17 days after they had been subjected to 0.25 to 5.0 Gy radiation. The rats given, during that interval after irradiation, polyunsaturated phosphatidylcholine (PC) at 300 mg/kg body weight daily had no dyslipoproteinaemia. PC prevented the...

In male albino rats a single dose of radiation, 0.25 to 50 Gy, resulted, within 10 to 17 days, in the development of atherogenic dyslipoproteinaemia inducing increased concentrations of total and free cholesterol, LDL cholesterol and reduced values of HDL cholesterol and decreased rates of...
