BACKGROUND Age-related changes in renal histomorphology are described, while the presence of glomerulonephritis in dogs with pyometra is controversial in current literature. METHODS Dogs with pyometra were examined retrospectively for evidence of secondary renal damage and persisting renal disease through two retrospective studies. In Study 1, light microscopic lesions of renal tissue were gr...

The extracellular matrix of the cervix that comprises collagen, elastin, proteoglycans and glycosaminoglycans (GAGs) is thought to have an essential role in cervical relaxation. This study investigated the proportion of collagen and smooth muscle as well as the GAGs in cervices obtained from healthy bitches at different stages of the estrous cycle and bitches with open- and closed-cervix pyomet...

INTRODUCTION As a consequence of poor productivity caused by a long anoestrous period, considerable research effort has been given to oestrus induction in dogs to enhance the productivity of young dogs and to preserve breeds. MATERIALS AND METHODS Oestrus was induced in 30 anoestrous bitches more than three months after the last oestrus. Bitches orally received fermented rice punch with or wi...

Data relating to reproductive parameters of German shepherd bitches were collected from registered German shepherd dog (GSD) breeders with information kept over a 15-year period (1982-1997). The information obtained was verified using the East African Kennel Club records. A total of 594 bitches from 280 breeders were recorded. From these, 798 heats were observed, 594 of which were used for bree...

Tumors of the reproductive system in bitches can affect any its anatomical structures. The predominant lesions are those appearing vagina and vulva, accounting for about 2.4-3% all tumors bitches, followed by ovarian – 0.5-1.2%, while uterine rare it is difficult to even estimate their incidence. most common type tumor granulosa cell (GCT), which originates from cells Graff follicle. In uterus,...

Canine pseudopregnancy is a syndrome, characterized by signs such as nesting, weight gain, mammary enlargement and lactation, which appear in nonpregnant bitches 6 to 12 weeks after estrus. The intensity of these signs is extremely variable among bitches. Metergoline is essentially a serotoninergic antagonist that inhibits prolactin secretion. A total of 24 cross and pure-bred, overtly pseudopr...

Companion animals, including bitches, may be exposed to zearalenone (ZEN) toxins that are often present in feed, and ZEN intoxication may lead to ovarian dysfunction. This study involved evaluation of the degree of ZEN-induced hypo stimulation of ovary by determination of proliferative and apoptotic indices and description of the ultra-structural organization of ovarian follicles in pre-puberta...

Canine embryos (8-cell to blastocyst stages) frozen-thawed using the slow-freezing method with glycerol (four recipients) or dimethyl sulfoxide (three recipients) as a cryoprotectant and vitrified-warmed using the Cryotop method (five recipients) were surgically transferred into the unilateral uterine horn of recipient bitches. As a result, the morphology of embryos frozen-thawed using the slow...

Objective- This study refers to the role of ultrasonography in the diagnosis of mammary gland tumor in bitches as a complementary diagnostic method and its ultimate goal is to evaluate the results of mammography with the positive results of ultrasonography. Design- Prospective study. Animals- 12 German Shepherd bitches with swollen mass in the mammary gland region (group I) and 12 h...

Zearalenone is an estrogenic mycotoxin that often contaminates plant material used in the production of feeds for companion animals. Small daily doses of ingested zearalenone--a competitive substrate modulating the activity of enzymes participating in estrogen biosynthesis at the pre-receptor level--can induce subclinical symptoms of hyperestrogenism in bitches. The objective of this study was ...
