Ten clinically healthy New Zealand White rabbits from both genders, weighing from 3.5 to 3.7 kg were used. The blood plasma concentrations of total cholesterol and triglycerides were 1.45 ± 0.15 mmol/L and 0.63 ± 0.01 mmol/L, respectively. The highest amount of pericardial adipose tissue was observed around the free surface of the right ventricle and the apex of the heart. The average mass of pericardial adipose tissue was 3.72 ± 0.24 g (0.1% of body weight and 47% of heart weight). By ultrasonography, pericardia adipose tissue was visualized as a moderately echoic homogeneous structure against the hyperechoic myocardium of the right ventricle. Its thickness was 3.2 ± 0.26 mm. The results of the present study showed that the rabbit was a suitable model for monitoring of quantitative changes in visceral fat depots in mammals, allowing their study in vivo by u...

MATERIAL AND METHODS: The pelvic urethra from six male cats and the urethra of six female cats, all clinically healthy and sexually mature. The expression of acid and alkaline phosphatase was detected by Gomori staining. RESULTS: The enzyme histological investigation of pelvic urethra in male cats showed that the most significant localization of acid phosphates activity was observed in the propria and adventitia of pelvic urethra, followed by apical parts of epithelial cells in disseminated part of the prostate and in the lumen of glandular tubules. In the lumen of disseminated prostatic alveoles, no alkaline phosphatase activity was detected. In female cats, the strongenst acid phosphatase activity was established in the con...

MATERIALS AND METHODS: The prostate glands of 12 sexually mature, clinically healthy male European Shorthair cats at the age of 1–2 years, weighing 2.8 tо 4 kg were investigated. The localization and the shape of basal cells were determined in semi-thin and ultrathin cross sections by light and transmission electron microscopy. RESULTS: Epithelial basal cells in feline prostate alveoli did not attain the alveolar lumen and formed an incomplete, discrete boundary layer, located in close vicinity to the basal membrane. These cells are observed as an occasional and rare epithelial population in the alveolar part of feline prostate parenchyma. The shape of alveolar basal cells varied from oval and triangular to irregular. Basal cells were also observed in the epith...

MATERIALS: We studied 30 colchis pheasants, divided in three groups (each group was consisted of 5 males and 5 females) at 15, 17 and 19 weeks of age. METHODS: Following euthanasia and evisceration, the digestive tract was separated in segments, corresponded to its different parts (esophagus, crop, proventriculus, gizzard, small intestine, caeca and rectum). The weight of digestive structures, heart, liver, spleen and testicles was determined by electronic scale and the length of the tubular digestive organs was measured with ruler and graph paper. The results were collected and recorded. The obtained data was processed via variable statistical methods. RESULTS: The body weight of the female birds was significantly lower than that of the male ones. In males the gizzard’s percent decreased significantly through the whole investigative period. The proventriculus and heart proportions were almost the ...

We proved that the used test was quick, easy to perform, convenient to set up, and not stressful for the subjects as it complied with the requirements for humane treatment of animals. According to our results, Labradors were most courageous and stable, followed by the Boxers and the German Shepherds.

The material was processed by conventional histological and histochemical methods. Histological preparations were formalinparaffin histoslices stained with haematoxylin (according Erlich) eosin. Paraffin slices from material fixed in Carnua’a solution were stained with Maurice alcian blue, followed by a PAS reaction for viewing free and conjugated polysaccharides. Differentiation of glycosaminoglycans was done by histochemical tests using alcian blue at pH 1.0 and pH 2.5. The light microscopic study of the heart ventricle walls in the cat showed structural identity compared with that of other mammalian species. Histochemical reactions established that the heart ventricle myocardium contains both free polysaccharides (glycogen) and glucosaminoglycans of the nonsulphate type.

The purpose of the present investigation was to determine its topography, morphological traits and some morphometric parameters in Bulgarian White × Landrace pig crosses. It was found that TPE was situated in pars laryngea pharyngis, dorsolaterally to vallecula epiglottica on the lateral syrface of lig. thyroepiglotticum. It is a paired macroscopically visible formation with grooves and the following dimensions (mean ± SEM): length – 15.8±0.4 mm in male and 16.2±0.4 in female; width –8.3 ± 0.1 mm in male and 8.2±0.1 mm in female. The shape of the tonsil is mainly elliptical, and in some instances – oval. It is sharply delineated and prominated over the adjacent tissues. On longitudinal sections, the number of lymph nodules was 75.0±0.9 in male and 76.2±0.9 in female pigs, whereas on transverse sections –33.4 ± 0.9 and 34.9±0.9 respectively. The stratified...

МATERIAL AND METHODS: Seven clinically healthy mongrel male dogs at the age of 3−4 years and body weight of 10−15 kg were submitted to transverse computerized axial tomography (CAT) with cross section thickness of 5 mm. RESULTS: The CT image of canine prostate is visualized throughout the scans of the pelvis in the planes through the first sacral vertebra (S1) dorsally; the bodies of iliac bones laterally and cranially to the pelvic brim (ventrally). The body of prostate appears as an oval homogenous relatively hypo dense finding with soft tissue density. The gland is well differentiated from the adjacent soft tissues. CONCLUSION: By means of CT, the cranial part of prostate gland in adult dogs aged 3−4 years exhibited an abdominal localization.
