SUMMARY Six groups each of 12 male albino rats were reared from day 21 of life at temperatures of 23, 34 or 37 °C. While the rats survived for unlimited periods at 23 and 34 °C, the animals reared at 37 °C succumbed within 5 days to heat stress. The latter group, when injected s.c. or i.p. with 50 mg dehydroepiandrosterone (DHA)/kg/day were no longer affected by the heat. During this treatment thyroid epithelial cell height doubled, colloid decreased by 20%, connective tissue did not change, the basic metabolic rate decreased by 10% and rectal temperatures of the treated rats increased with the ambient temperatures. Body weight increased only slightly, pituitary TSH decreased by 25%, serum TSH increased by over 50%, thyroxine and 125I uptake increased by 200%. The survival of the DHA-treated rats was apparently secured by blocking the hypothalamic thermoreceptors.

Standard Pressure

A standard volume of saline was introduced at standard pressure into the reflected subcutaneous tissues in 79 male albino rats, forming gelatinous bullae. The rate at which the saline was lost from the bullae after it had been dissected free was estimated by periodic weighings, and a velocity constant of this rate was derived. There was found to be a linear relationship between this constant and the weight of the animal. It is believed that the injected saline combines with the connective tissue, and that the alteration with body weight of the rate of loss of the saline subsequent to the injection is an expression of the change of the water-binding ability of this tissue.

Histochemical Changes

ABSTRACT Histochemical changes in the activities of acid phosphatase, considered to be characteristic of lysosomes, and of alkaline and adenosinetriphosphatase, were studied during the period of regression of deciduomata in the uterus of the pseudopregnant rat. The activity of alkaline phosphatase and adenosinetriphosphatase declined rapidly prior to and during the period of involution. A rise in the activity of acid phosphatase began antimesometrially at the periphery of the deciduomata, before shrinkage was evident in the histological preparations. Acid phosphatase activity remained high during the period of regression and subsequently declined. Enzymatic activity was also high in the metrial gland cells, and in the macrophages which appeared in the uterus and apparently contributed to the breakdown and removal of the deciduomata. Changes were also demonstrated in the amount of free lipids and connective tissue components of the uterus. Great variability was noted in the appearance of uteri from animals killed at the same time intervals following stimulation during the period of regression of deciduomata and this variability was related to the time of occurrence of the first ovulation terminating the period of pseudopregnancy in deciduomata bearing rats.

Histochemical Changes

The present study was aimed to examine histochemical changes in the Harderian gland of pre and post hatched chicks from 11 day of incubation to 24 days of age. In pre hatched groups, the gland was in the developing stage. There was no well defined parenchyma, septa and capsule in early embryonic stage. Histochemical observation revealed that weak or negligible activity of PAS, AB/PAS and Sudan black B was seen in epithelial lining of Harderian gland on 18th and 20th day of incubation. The gland was compound tubule-acinar type at 20th day of incubation, consisted of capsule, parenchyma and stroma. PAS activity was seen in the capsule, septa, epithelial lining of acini and tubule and interstitial connective tissue cells. PAS activity was aggregated towards the apical part of the tubular epithelium as well as at the free luminal surface epithelium of the acini. PAS activity increases with the development of connective tissue component of Harderian gland with the advancement of age. The Harderian gland was predominantly mucus and lipid secreting gland. All epithelial cells of the glandular unit of Harderian gland contain both neutral and acidic mucin. Intense AB-positive activity was seen at the apex of tubule with the advancement of age. Sudan black B activity was recorded in the cytoplasm of epithelial lining of tubule and acini of the Harderian gland and their presence increases with age.
