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...
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...
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...
A study was conducted during 1975 and 1976 to evaluate
the use of chemically cured pasture as a flushing feed for
ewes in western Oregon.
In 1975 (0.56 kg/ha) and 1976 (0.28 kg/ha) paraquat
was used to chemically cure hill pasture forage when perennial
ryegrass (Lolium perenne L.) and tall...
