Vascular endothelial growth factor (VEGF) expression in histological endometritis in the bitch: An immunohistochemical study.

This work aimed to study the immunolocalization of vascular endothelial growth factor (VEGF) and its FLT-1 receptor (VEGFR1) in systemically healthy bitches with and without endometritis (END). Thirty-one uterine samples from mixed-breed, systemically healthy diestrous bitches, were included in the study. The bitches were divided into three groups after histological evaluation (normal endometrium [n = 8]; acute-END [n = 8]; subacute-END [n = 5]; chronic-END [n = 10]).

Serum progesterone concentration, volume, and apoptosis of corpora lutea in early, middle and late diestrus in the bitch.

The aim was to study number, volume, apoptosis of corpora lutea (CL), and serum P concentrations in early, middle, and late diestrus of dogs. Thirty-six bitches were ovari-hysterectomized (OVX): Early Diestrus (Group [G]1; OVX 20 days after end of estrus [DEH]); Mid-diestrus (GII; OVX between 21 and 40 days after DEH), and Late-diestrus (GIII; OVX between 41 and 60 days after DEH). Before OVX a blood sample was collected to quantify P.

Reestablishment of sperm quality after long-term deslorelin suppression in tomcats.

The aim of the study was to determine the time after treatment with a 4.7 mg deslorelin implant until Tomcat spermatogenesis activity was restored, and seminal parameters reached pre-implant values. Tomcats (n = 6) were randomly assigned to one of two treatments.
