A 6-year-old lactating Holstein cow with a history of repeat breeding syndrome (failed to conceive afterthree artificial inseminations (AI) with fertile semen) was referred to the Veterinary Teaching Hospital of theSchool of Veterinary Medicine, Shiraz University. According to the history, neither abnormal clinical signs,nor uterine discharge had been observed subsequent to AI. The cow had show...

The total number of corpora lutea developed in the left and right overies of 170 white-toothed shrews (Crocidura russula monacha) differed significantly, showing a functional dominance of the left ovary. Blastocytes were equally distributed in both uterine horns.

Twenty-four pregnant Landrace and Yorkshire gilts were utilized to examine the relationship between myometrial activity and intrauterine embryo migration. On d 2 (1st day of estrus = d 0), embryos were flushed from one oviduct and transferred to the opposite oviduct. Uterine horns were ligated at the uterotubal junction on the flushed side and 40 and 50 cm posterior to the uterotubal junction o...

The modulatory effects of gestational age and circulating concentrations of progesterone, 5-pregnane-3,20-dione, and estradiol-17 on the uterine sex steroid hormone receptor levels of the African elephant were investigated. Uterine tissue biopsies and blood samples were obtained from animals culled in the Kruger National Park. Estrogen and progesterone receptor concentrations were determined in...

A single instillation of an aqueous suspension containing 40 mg. of quinacrine hydrochloride into the uterine horns of adult rats prevented implantation for at least 4 weeks. A suboptimal dose of 5 mg. could be potentiated by the addition of epinephrine or metaraminol. In some animals, the use of the quinacrine hydrochloride suspension resulted in atrophy and necrosis of the treated uterine hor...

Amines and/or peptide-producing cells, deserving to be called paraneurons, were demonstrated in the urethro-prostatic complex of the man, rabbit, buffalo and sheep and in the uterine horns of the pig, horse and mouse, by means of histochemical, immunohistochemical, immunofluorescent and double labeling immunofluorescent techniques. In particular, the urethro-prostatic complex of the sheep conta...

Experimental control of fertility has been accomplished by inserting foreign objects in the uterus. Doyle & Margolis (1963) found that a suture in the uterine lumen of the rat prevented implantation of blastocysts. This was soon followed by similar studies on the rabbit (Adams & Eckstein, 1964), cow (Hawk, Conley, Brinsfield & Righter, 1965) and ewe (Hawk, 1965). A local inhibitory effect on lu...

Uterine tumors are rare in cats, the most common clinical signs observed include presence of abdominal mass, weight loss, anorexia, pain, and vaginal bleeding in some cases. On the other hand, the most commonly diagnosed and thus the most important disease of feline uterus is cystic endometrial hyperplasiapyometra complex (CEH-P). A 12-year-old, sexually intact, female domestic shorthaired cat ...
