Influence of certain chemicals on the sensitivity of rat embryos to X-irradiation

Creator:

Loawhakasetr, Pathom

Abstract:

The effect of 2-aminoethyl-2-thiopseudourea[superscript .]Br[superscript .]HBr (AET), 2-mercaptoethylamine[superscript .]HC1 (MEA) and trisodium calcium chelate of diethylenetriaminepentaacetic acid (CaNa₃DTPA) on the radiosensitivity of rat fetus was investigated. A total of 1256 fetuses were critically examined. Exposure of rats to 200 r whole-body X-irradiation at 9.5 days of gestation resulted in a...

The effects of exogenous melatonin on the plasma levels of interstitial cell stimulating hormone in sheep

Creator:

French, Larry Robert

Abstract:

There is an increasing body of evidence that the pineal gland acts as a neuroendocrine transducer, translating neural information about environmental lighting condition into hormonal information. In the rat, light controls the production of melatonin which acts via the hypothalamic-hypophyseal pathway to control the function of the gonads, A similar...

Ultrastructural and cytochemical studies of the oviduct

Creator:

Nayak, Ramesh Kadbet

Abstract:

The ultrastructure of the oviduct and the hormonal induced alterations in the cellular organelles of prepubertal and ovariectomized rabbits have been studied with electron-microscopic histochemical methods. The pseudostratified epithelium of the oviduct in prepubertal rabbits contained both ciliated and secretory cells. The secretory cells showed apocrine projections filled with electron-dense...
