The 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 ...
متن کاملPGF2 alpha-induced milk ejection in ewes having cyclic or pregnant corpora lutea.
The production of luteal oxytocin in ewes, resulting from the intrajugular injection of 200 micrograms of PGF2 alpha, could be determined by the increase in intramammary pressure. This simple indirect method of measuring the activity of the corpus luteum enabled easy detection of renewed post-partum ovulation or the onset of pregnancy. The response was monitored every two days between Days 0 an...
متن کاملComparison of induced corpora lutea from prepuberal gilts and spontaneous corpora lutea from mature gilts: in vitro progesterone production.
Prepuberal (P) gilts were induced to ovulate with pregnant mare serum gonadotropin followed 72 h later by human chorionic gonadotropin (hCG). Three P gilts and three mature (M) gilts each were ovariectomized on d 10, 14, 18, 22 and 26 (d 0 = day of hCG for P gilts and onset of estrus for M gilts). Gilts ovariectomized on d 14, 18, 22 and 26 were hysterectomized on d 6 to ensure maintenance of t...
متن کاملComparison of induced corpora lutea from prepuberal gilts and spontaneous corpora lutea from mature gilts: hydroxysteroid dehydrogenase activity.
The activity of hydroxysteroid dehydrogenases was histochemically quantified in corpora lutea (CL) from prepuberal gilts induced to ovulate and mature gilts. Prepuberal (P) gilts, 120 to 130 d of age were induced to ovulate with 1,500 IU pregnant mare serum gonadotropin (PMSG) followed 72 h later by 500 IU human chorionic gonadotropin (hCG). Three P gilts and three mature (M) gilts each were ov...
متن کاملExpression and localization of prohormone convertase 1/3 (SPC3) in porcine ovary.
Tissue distribution and cellular localization of PC1/3 mRNA in porcine tissues were examined by ribonuclease protection assay and in situ hybridization. PC1/3 mRNA was detected mainly in the corpus luteum of pregnant sow and brain. Within the ovary, PC1/3 and relaxin transcripts colocalized within large luteal cells. Levels of PC1/3 transcripts in corpora lutea increased as gestation advanced, ...
