In this work it was determined the effects of vegetal fat enriched diets on the young rabbit skeletal muscle composition and structure following a 20 days period of experimental feeding. At the end of the experimental period, the percentage of muscle fat in the Biceps femoris muscle was 1.12% in the control group, 1.21% in 3% supplemented group, 2.38% in 5% supplemented group and 2.54% in the 7% fat supplemented group. The protein content of same muscle for the control group amounted to a rate of 22.92% showing a decreasing trend in the fat supplemented groups: 22.75%, 22.19% and, respectively, 22.02%. Water content of muscle in the control group was 76.87%, while in the experimental groups the values were reduced: 76.31%, 75.53±2.21% and, respectively 75.30±3.09%. The percentage of mineral salts in the control group amounted to a value of 1.27% while the experimental values were as follows: 1.22% in 3% fat supplemented group, 1.16% in the 5% supplemented group and 1.1% in the group of 7% fat supplemented rabbits. The final pH values of same muscle have relatively low growth, proportionally to the concentration of fat, in order of 5.72, 5.60, 5.53, the maximum being in 7% fat supplemented group, while the control group that value amounted to 5.68, 24 hours from sampling. Histological analysis reveals the structure of muscle fibers consisting in increasing the percentage of slow oxidative vs. fast oxidative fibers.

Population health surveillance provides real-time information about dietary factors that create health problems for a certain segment of the population or the entire population. It warns about the measures to be taken to prevent these problems or reduce the effects of their manifestation. It is an efficient way by which to intervene when there is a tendency for the spread of disease outbreaks which involve specialists with increased competences in various fields. The industrialization, free movement of goods and persons, urban population growth and decline of rural communities, are some of the factors that threaten the preservation of the population’s health. The aim of this research is to investigate the impact of official controls in food quality and safety surveillance on the health of the population, the lasting impact being the reduction of diseases due to the foods consumption.

Rostral nasal concha presents stratified squamous cornified epithelium. It consists of a basal cell layer cube, slightly irregular. It goes to the surface of cell columns perpendicular to the basal layer. The skeleton is composed of hyaline cartilage cones and lamina propria contains numerous blood vessels. Middle nasal concha is located in the respiratory region of the nasal cavity. Presents a hyaline cartilaginous skeleton, bounded by a thickened pericondru. It is covered with a respiratory type mucosa and with ciliated columnar pseudostratified epithelium with goblet cells. In the structure of the alveolar mucosa lists numerous large aspect mucous glands that open directly to the surface epithelium. Goblet cells are rare and their function is taken over by alveolar glands. In the conjunctive space between glands and basement membranes we find limphoid cells nucleis represented by: lymphocytes, plasma cells and macrophages.

Using horses for sport requires preparation and optimization of physical and mental qualities, both contributing to achieving the desired performance. Energy metabolism in sport horses is strongly influenced by the intensity and duration of exercise. Thus, in short duration and high intensity efforts, most of the chemical energy needed for muscle contraction is supplied by lactic anaerobic metabolism. This metabolic pathway lead to lactic acid byproduct, whose accumulation, in muscle and blood, will influence the level of serum electrolytes .These imbalances lead to muscle fatigue phenomenon.80percentage of the mechanical energy is released as heat during exercise. On horse, heat is dissipated by evaporation during exercise mainly by the evaporation of perspiration. Through this mechanism, the horse makes thermal homeostasis, but the price of electrolyte losses often important. The magnitude of these losses is linked to the needs of thermoregulation, which will be influenced by the intensity and duration of effort and the impact on the horse of environmental factors. Biological material which is the subject of research, belongs to Sport Club Dinamo-Bucharest. Were studied both mares and stallions, Romanian Sport Horse and English Pure Blood, aged 5 to 10 years, specialized and well trained for full test riding. Calcium, at the end of the full test riding decreased at all trials, correlated with the loss phenomenon of the electrolyte through perspiration. Sodium values decrease at steeple and obstacles phases. At cross phase, sodium levels increased immediately after effort. Chloride values decrease insignificant statistically at cross and obstacles and increase also insignificantly at steeple phase. Phosphorous values had also insignificant differences but they decreased after effort. These results show a good training in sport horses,but is necessary to check the diet content in minerals, because they are eliminated through perspiration.

Identification of Salmonella spp. carrier sows is an important factor for the implementation of control programs at farm level. In this study we observed the transmission of Salmonella on the farm during the technological flow, by faecal sampling from gilts, their piglets until weaning age, the piglets after weaning age, and from youth at fattening, prior slaughtering. Identification and isolation of Salmonella was done by two methods: SR EN ISO 6579:2002, or by molecular methods (PCR). The prevalence of Salmonella spp. after examination of (n=150) samples of faeces was 50% at sows and their piglets , observing a slight increase in piglets after weaning (78.57%) and the fattening pigs (90%). The most common serovars isolated were S. Typhimurium, S. Derby and S. Newport. Study results indicate that sows are a source of contamination of piglets, and the presence of salmonella during other stages may be due to environmental stress factors and the Salmonella carrier state.

Written by Dumitru MILITARU, Virgilia POPA, Daniela BOTUS, Beatrice STIRBU

Artemisinin, an extract of sesquiterpene lactone endoperoxide obtained from Artemisia annua, is routinely used in the treatment of malaria and various forms of human cancer. In order to extend its therapeutic range on animals and to set up models for testing similar extracts from other plants, studies were done on Artemisinin cytotoxicity on chicken embryo fibroblasts (CEF) in parallel with tests on Vero cells and the effect assessment on Salmonella spp strains of avian origin (4 Salmonella enteritidis, 2 S. typhimurium, 1 S. gallinarum). The cytotoxic effect was recorded for Artemisinin amounts higher than 177.10 nM on CEF and for 4.42 nM on Vero cells. In disk diffusion antibiogram the two concentrations had no antibacterial effect (inhibition diameters were of 6-9 mm)

SURGICAL REDUCTION OF A TOTAL ENTROPION IN A CHOW-CHOW USING RHYTIDECTOMY

Published in Scientific Works. Series C. Veterinary Medicine, Vol. 19 ISSUE 3
Written by Iuliana IONASCU, Andreea Elena GEORGESCU, Constantin VLAGIOIU

Entropion is the inversion of all or part of the margin of the eyelid such that the outer lid skin contacts the conjunctival and/or corneal surfaces, causing damage. The degree of entropion is considered to be mild, moderate and severe. Could be lateral, medial, angular and total; may affect the lower lid, or the uper lid. The total entropion is frequently seen in the Chow-Chow breed. This case reports 2 male Chow-Chow breeds, 3 and 4 years old, which were operated on twice for total entropion using classic techniques. This breed has prominent lateral and frontal folds, that cause the entropion. The classic techniques do not give the expected results and recurrences are common .These dogs can not see and the cornea is injured. The rhytidectomy is the only successful therapeutical option and it consists of the ablation of the prominent folds. The surgery was a success, both dogs can see and the corneal lesions healed.
