Plasma concentrations of progesterone and 13,14-dihydro-15-keto prostaglandin F-2 alpha in pregnant, pseudopregnant and hysterectomized pseudopregnant mice.
Hysterectomized pseudopregnant mice had plasma progesterone concentrations on Days 6, 8, 10 or 12 after mating that were greater (P less than 0.05) than those of intact pseudopregnant mice and lower (P less than 0.01) than those of pregnant mice. Concentrations of 13,14-dihydro-15-keto-prostaglandin F-2 alpha on Days 6, 7, 8, 9 or 10 after mating were lower (P less than 0.05) in pregnant and hi...
متن کاملConcentrations of catecholamines, ascorbic acid, progesterone and oxytocin in the corpora lutea of cyclic and pregnant cattle.
To determine if there are inter-relationships between progesterone, oxytocin (OT), dopamine (DA), noradrenaline (NA) and ascorbic acid, these compounds were measured in the corpus luteum (CL) from cattle at different stages of the oestrous cycle (n = 42) and from 1-5 months of pregnancy (n = 27). They were measured by radioimmunoassay (RIA), high performance liquid chromatography (HPLC) and col...
متن کاملExpression of type I GNRH receptor and in vivo and in vitro GNRH-I effects in corpora lutea of pseudopregnant rabbits.
The expression of type I GNRH receptor (GNRHR-I) and the direct role of GNRH-I on corpora lutea (CL) function were studied in the pseudopregnant rabbit model. Immunohistochemistry evidenced GNRHR-I and GNRH-I in luteal cells at early (day 4 pseudopregnancy)-, mid (day 9)-, and late (day 13)-luteal stages. Real-time RT-PCR and western blotting revealed GNRHR-I mRNA and protein at the three lutea...
متن کاملEffect of number of corpora lutea and fetuses on concentrations of progesterone in blood of goats.
The objectives of this study were to assess relationships between 1) number of corpora lutea (CL) and concentrations of progesterone (P) in plasma of goats from onset of estrus (d 0) to d 45 of pregnancy and 2) concentration of P and number of fetuses on d 45. Blood from 79 pregnant goats was obtained on d 0 and 1 and at 48-h intervals thereafter to d 25 of gestation. Additional samples were co...
متن کاملThe distribution of corpora lutea and ovarian follicular development in pregnant goats.
The main objective of the study was to determine the number of growing follicles (diameter>or=4 mm) with regards to the distribution of corpora lutea (CL) on the ovaries in pregnant goats. Growing follicles with a diameter greater than 5 mm i.e. large follicles were also recorded and analyzed. Daily ultrasonography (USG) examinations of ovaries were made in six Polish White Goats starting from ...
