proliferative phase

proliferative phase

[-lif′ərətiv]

the phase of the menstrual cycle after menstruation. Under the influence of follicle-stimulating hormone from the pituitary, the ovary produces increasing amounts of estrogen, causing the lining of the uterus to become dense and richly vascular. The phase is terminated by rupture of a mature follicle and subsequent ovulation. Also called proliferative-follicular phase. Compare menstrual phase, secretory phase.

proliferative phase

The early/preovulation half of the menstrual cycle, which is initiated by a small peak in serum FSH and histologically characterised by short glands with increased mitotic activity.

proliferative phase

The part of the menstrual cycle between the end of menstruation and the next ovulation. During this stage the womb lining (endometrium) thickens and becomes suitable for implantation of the fertilized ovum.

proliferative

pertaining to or emanating from proliferation.

proliferative dermatitis

see strawberry footrot.

proliferative enteropathy

of swine, see porcine intestinal adenomatosis; a disease of weaned foals presenting with lethargy, weight loss, a varying degree of fever, inappetance, a potbellied appearance with a rough coat, colic, diarrhea and ventral edema associated with a pronounced hypoproteinemia. The disease is a protein losing enteropathy associated with a proliferation of crypt epithelial cells in the terminal small intestine and thickening of the intestine at this site. The causative agent, Lawsonia intracellularis, is present in proliferating cells. The disease responds to a long treatment course with erythromycin and rifampicin.

proliferative exudative pneumonia

of lambs see enzootic pneumonia.

proliferative hemorrhagic enteropathy

an acute or peracute disease of recently weaned pigs and also of replacement gilts. Characterized by anemia and dysentery, and a proliferative, hemorrhagic lesion in the terminal ileum and proximal colon, and a high death rate. The underlying intestinal abnormality is porcine intestinal adenomatosis caused by Lawsonia intracellularis but the reason for the hemorrhagic complication is not known.

proliferative kidney disease

important disease of salmonids; caused by a pre-spore stage of a myxosporean species presumably carried by other fish inhabiting the same waters.

proliferative optic neuropathy

a raised gray mass on the surface of the optic disk but there is no effect on vision.

proliferative phase

in uterine activity; called also follicular phase. The lining epithelium of the uterus hypertrophies and becomes congested and edematous.
