... strains). Both RCS and Wistar strains responded to constant light (LL) exposure by attaining persistent vaginal cornification at the same rate. In addition, both RCS and Wistar strains regained normal estrous cycles when moved from LL to control lighting (LD). Therefore, an intact retinal photoreceptor...

... of the adrenalectomized rats were exposed to constant light (LL) for an additional 8 weeks, at which time all animals were sacrificed. Operated rats with regenerated adrenal tissue, determined either by macroscopic examination or serum corticosterone assay (about 50% of the rats), were excluded from all data calculations...

... of darkness. Twice daily injections of vasopressin tannate markedly reduced water consumption of Brattle-boro rats and also re-established nearly normal nocturnal drinking patterns. The depressive effects of constant light on water intake of albino rats were abolished by nephrectomy; this response may...

...Béla E. Piacsek; W.J. Streur Immature female rats, raised in either cyclic light (LD; 14 h light/10 h dark) or constant light (LL) were divided into 4 groups and given daily injections of estradiol benzoate (5, 10, or 25 ng) in 0.1 ml sesame oil starting at 24 days of age. Control animals received...

...K. Brown-Grant Female albino rats exposed to constant light are anovulatory and show an extensive loss of retinal photoreceptors but resume regular ovarian cycles when returned to light-dark conditions. If returned to constant light such animals develop persistent vaginal cornification at the same...

...L.P. Morin The effect of pinealectomy or constant light on hamster ovulatory and body weight responses was examined. When lights were on from 5 a.m. to 7 p.m., the critical period for phenobarbital (PB) blockade of ovulation was centered around 1.45 p.m. Constant light (LL) rendered the critical...
