Aflatoxin and ochratoxin are the most common mycotoxins in poultry feed. Their presence contributes to significant health disorders and decrease in production performances. This leads to considerable economic losses for the poultry industry by increasing mortality, decrease in body weight, number and quality of eggs, greater feed conversion and immunosuppression. The risk associated with mycotoxin residues in poultry meat and eggs represents a concern in human health. The present article reviews the most important scientific literature on aflatoxin and ochratoxin contamination in poultry and their relationship with food safety. Recent studies showed that young poultry are more sensitive to aflatoxin and ochratoxin than adults. Ochratoxin has high affinity for liver and kidney, meanwhile aflatoxin has high carcinogenic potential and hepatotoxicity. Lesions in the liver include hepatomegaly, hydropic degeneration, fatty changes, bile-duct hyperplasia and periportal fibrosis. In order to prevent and reduce the negative implications of these mycotoxins in poultry production, it is necessary to create both global and national strategies to reduce the amount of mycotoxins in grain, to use advance analytical techniques and to establish new limits concerning the maximum amount of mycotoxins allowed in poultry feed and products from poultry for human consumptions.

The investigations were performed on 10 specimens of each species horse and pony. Taken together, the anatomical region of the poney autopodium resembles that of the horse but there are some obvious features. Differences were found especially at the carpal and tarsal the phalanges.bones but also at the synovials of the antebrahio – carpal – metacarpal joint and less than

The importance of the study of the chicken’s genital apparatus coincides from an economical point of view with the acquirement of one of the main avian products for which this bird is selected: the egg. In birds only the left ovary and oviduct are developed. The mature ovary has a grape-like shape, suspended form the ceiling of the abdominal cavity, immediately under the cranial extremity of the kidneys. The oviduct is long and flexuous, leading from the ovary to the cloacae. Material and Methods: The research was carried out on the ovaries and oviducts harvested from 15 chickens of various ages (56 to 126 days) that were dissected using common techniques in the Comparative Anatomy Laboratory of the FVM Cluj-Napoca. The samples were also histologically prepared and examined using regular optical microscopy. Results and Conclusion: Following the examinations, the have noticed that in the first group age, the ovary has a smooth surface, at 98 days, its surface becomes uneven, while at 126 days, it completes its development, acquiring its classical grape-like shape. The 56 days and 98 days old oviduct cannot be divided into segments; only the 126 days old oviducts displays macro and microscopic segmentation. In conclusion, results indicate that the ovary and oviduct of chickens reach maturity at the ages of 126 days, when the birds become ready to produce eggs.

The study involved 400 non-sterilized dogs (232 males, 168 females) and 300 sterilized dogs (123 males, 177 females). Both groups have been divided in three subgroups: purebred, crossbreed and adopted community dogs. Four pathological events were questioned and correlated with spaying and neutering: obesity, pyometra, nervous lactation after pseudo-pregnancy and prostatic hyperplasia. In our study, reproductive disorders imposed the sterilization in 127 dogs (51.18% males, 48.81% females), of which: 37.00% (47/127) purebred, 41.74% (53/127) crossbreed and 21.26% (27/127) adopted community dogs. Prevalence of obesity was 18.40% (46/250) in purebred, 30.00% (72/250) in crossbred and 18.00% (36/200) in adopted community dogs. A correlation between obesity and sterilization in the population of dogs studied was not observed. Pyometra prevalence was 21.05% (24/114) in purebred, 18.26% (21/115) in crossbred and 16.19% (17/105) in adopted community bitch. Nervous lactation prevalence was 71.05% (81/114) in purebred, 58.26% (67/115) in crossbred and 19.05% (20/105) in adopted community bitch. Prevalence of prostatic hyperplasia was 10.29% (14/136) in purebred, 2.22% (3/135) in crossbred and 7.37% (7/95) in adopted community dogs. The highest prostatic diseases in group of purebred males were correlated with sterilization in old ages (86.95% after 2 years age). The low prevalence of prostatic diseases in crossbred and community males were correlated with high proportion of early age neutered dog (58% before 2 years age). Therefore, early sterilization of non-breeding dogs could be a good decision to reduce the unnecessary distress associated with reproductive pathology.

This study was undertaken to evaluate the antioxidative potential of ethylic fraction of nettle (Urtica dioica) in stressed mice. In this present study mice were divided into the four groups and each group containing five mice. Group I mice were orally administered with 1 ml of 0.9% NaCl with is the positiv control group. Group II mice were administered with ethylic fraction of Urtica dioica. Group III stressed mice were orally administered with 1 ml of 0.9% NaCl with is the negativ control group. Group IV stressed mice were administered with ethylic fraction of Urtica dioica. The activity of enzymic antioxidants (U/ mg of protein) such as catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) were found to be significantly high in ethylic fraction treated stressed mice when compared to the negative control mice. The levels of nonenzymic antioxidant such as reduced glutathione in the ethylic fraction treated stressed mice was found to be significantly higher than that found in control mice. These results suggest that nettle (Urtica dioica) has very good antioxidant and hepatic protective effect of oxidative stress in mice. Currently, the importance of oxidative stress in the pathophysiology of many disorders has been highlighted, thus use of this plant as an herbal medicine is highly recommended.

The purpose of this study was to evaluate the comparative efficiency of Tiamulin and Dimetridazole for treating and controlling swine dysentery. The growing performance was evaluated. Levels of average daily weight gain revealed significant differences (P < 0.0001) between Tiamulin and Dimetronidazole. We found strong positive correlation of the average daily gain and treatment with Tiamulin (P < 0.0001) and coefficient of determination (P < 0.001). For Dimetridazole, the correlation coefficient and the coefficient of determination have low values (P = 0.006).

Stem cells isolated from various tissues can self-renew and produce different cell types. Oral cavity may be a valuable source of mesenchymal stem cells (MSCs) that can be isolated and expanded in vitro, providing a unique reservoir of stem cells from accessible tissue resources. The aim of this study was to isolate and assess the multipotent characteristics of MSCs dog and human in order to cover gingival recessions in future with these cells. Human and dog MSCs were obtained from palatal subepithelial connective tissue, expanded and cultured in DMEM/F12 culture medium supplemented with 10% fetal calf serum (FCS) and antibiotics. The cell surface phenotype of the presumed palatal MSCs was characterized at the 4th passage. All flow cytometry measurements were made using a FACS Canto II flow cytometry system (BD Biosciences, San Jose, CA, USA) and analysed using the DIVA program. Our data confirmed that the isolated and cultivated dog and human MSCs cells have multipotent character based on specific surface antigen expressing (CD44, CD34/45, CD29).

Spinal-dorsum-lumbar musculature, located near the thoracic-lumbar spine and ribs, is divided into three longitudinal muscle systems, sideways, intermediate and medial, each of them composed of overlapping muscle bundles. These systems continue in the neck region. The research aimed to demonstrate the special development of this system in carnivores, compared with sheep, rapid movement within the first species being related to the possibility of hyperextension of the rachides.

At the age of 120 days in the seminal epithelium are present all types of cells of the seminal line - primary spermatocites, secondary spermatocites, spermatide and spermatozoa, that indicating onset of spermatogenesis process. Sertoli cells were observed in cross sections of seminiferous tubules, they are willing unistratal, with the nuclei located basal, polymorphous nucleolus sometimes triangular course. There are many cells in semen Sertoli epithelium, in peritubulary are located myofibroblastes. At cocks 180 days in seminal epithelium are present all cell types of the seminal line. Basement membrane of the seminiferous tubules is evident and intertubular connective tissue is PAS positive.
