Comparison of cystometric methods in female rats

Neurourology and Urodynamics, 2007
AbstractAimsRat cystometry is a common model used to investigate urinary storage and voiding function. The effect of cystometric instrumentation in rat studies might be a source of deviation from normal physiologic responses. We hypothesized that transurethral catheterization would produce obstruction‐related changes, and that suprapubic ...

PROLACTIN LEVELS IN THE PLASMA OF FEMALE RATS

Journal of Endocrinology, 1967
Abstract The isolation and identification of rat prolactin (Kwa, 1965; Kwa, van der Bent & Prop, 1967) made it possible to develop a radioimmunoassay method for the estimation of prolactin in plasma and in pituitary tissue (Kwa & Verhofstad, 1967). Results are now given for plasma levels of prolactin, expressed as ng./ml.

The role of the rhabdosphincter in female rat voiding

BJU International, 2004
OBJECTIVES To obtain information on the mechanisms of female rat micturition using a model in which pressure was measured in the bladder and distal part of the urethra corresponding to the location of the rhabdosphincter, providing information on the role of the sphincter in opening and closing the urethral ...

WAY100635 and female rat lordosis behavior

Brain Research, 2004
Sexually receptive proestrous rats with bilateral cannulae in the ventromedial nucleus of the hypothalamus (VMN) were infused with 200 ng of (+/-)-8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) or with 8-OH-DPAT plus varying concentrations (200 to 2000 ng) of the 5-HT1A receptor antagonist, N-[2[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]N-(2 ...

Storage of copulatory stimulation in the female rat

Physiology & Behavior, 1972
Abstract The copulatory intromissions, delivered by the male rat before ejaculating, trigger the progestational state necessary for ovum implantation and subsequent pregnancy in the female. Since the multiple intromissions' effect is cumulative, there must be some mechanism by which the stimulation from each of the intromissions is stored.

Episodic Corticosterone Secretion in the Female Rat

Hormone Research, 2008
Studies conducted in several laboratories have shown primate glucocorticoid secretion to occur episodically. In light of the methodological, as well as physiological importance of this finding, the present study was undertaken to determine whether the rat corticosteroid secretion also occurs episodically.

Curt Richter and the female rat

Appetite, 2007
Richter fully appreciated the fundamental biological importance of sex differences, in particular the challenges of female reproductive function to the two classes of behavior that most engaged him, endogenous rhythms and "self-regulatory" behaviors.

Laterization of spatial preference in the female rat

Life Sciences, 1983
Female rat pups were either left undisturbed in infancy and raised in lab cages or were handled in infancy and raised in enriched environments. In adulthood, animals underwent brain surgery consisting of: 1) a right neocortical ablation, 2) a left neocortical ablation, 3) a sham operation, or 4) no surgery.

Urethral catheterization of the female rat

Lab Animal, 2011
Urinary tract catheterization of the rat may be required for a variety of clinical and experimental reasons. The external urinary orifice is easily visualized and rests anterior to the vaginal opening, making urinary tract catheterization easier in the female rat than in other species.

Social factors and puberty in female rats

Journal of Endocrinology, 1985
ABSTRACT The effects of postweaning social conditions on the age of puberty were studied in female rats from an early-and a late-maturing strain. The postweaning living conditions consisted of the presence or absence of an adult rat (intact or gonadectomized male, or intact female), or of bedding soiled by adult males.
