The purpose of this study was to investigate the changes in histological structure and the expression of lactoferrin (LF) in the uterus and ovaries of dogs during the normal estrus and with pyometra. Masson's, VVG and PAS histochemical staining were used to observe the histological characteristics...

This study assessed the most suitable behavioral test for discrimination of the odor of female dog urine during estrus and anestrus, to identify chemical compounds acting as female pheromones. Twelve male dogs were used for testing. Urine samples were collected from 16 females in estrus, 5 females...

The effects of gonadotropin, serum and follicular fluid on the in vitro maturation of canine oocytes were examined. Additionally, spindle size and spindle migration in MI-stage oocytes derived by in vivo or in vitro maturation were evaluated for the first time. Mature oocytes collected from beagle ...

Studies in female dogs proved the measurement of anti-Müllerian hormone (AMH) as a diagnostic tool to distinguish ovarioectomized from intact females or to diagnose ovarian remnant syndrome. Furthermore, its usability to diagnose a granulosa cell tumour and predict litter size was also investigated ...

Poly-ovular follicles are defined as those with more than one oocyte present in single follicles. The occurrence frequency of this follicle type is higher in canines than that in other species. This study aimed to evaluate the in vitro meiotic maturation of dog oocytes from this follicle type in...

Superoxide dismutase (SOD) and glutathione peroxidase (GPx) are two important antioxidant enzymes involved in tissue homeostasis by protecting cells and tissues from an accumulation of reactive oxygen species. Information concerning antioxidant enzymes in the canine uterus is almost inexistent....

Eleven Atlas Shepherd bitches of 4 years old, weighing between 15 and 16 kg who had an end stage of metestrus, have received treatment with bromocriptine, available in medicine human (Parlodel® 2.5 mg breakable tablet box of 30 tablets) orally to anticipate estrus. The dosage adapted for the...

Studies in cats and dogs have proven the usefulness of anti-Müllerian hormone (AMH) as a diagnostic tool to determine the castration status or to diagnose ovarian remnant syndrome. Yet the secretion pattern of AMH over the estrous cycle in queens has not been investigated so far. Seven healthy...

The current study was designed to evaluate the changes in vaginal cytology and serum progesterone and estrogen concentration in anestrum bitches treated with a combination of FSH and LH. Seven healthy Mongrel anestrum bitches were treated with daily administration of 75 I.U. FSH plus 75 I.U LH for...

The cardiovascular parameters of canine bitches were assessed during the estrous cycle. A total of eleven mongrel female dogs were enrolled in a longitudinal prospective investigation. Six animals were bred during the study and were assigned into group I, in which evaluations were performed during...
