PHOTOPROTECTIVE MECHANISMS OF THE SKIN AND THE POSSIBILITY OF THEIR CORRECTION VIA SECONDARY PLANT METABOLITES

Posted in 2022, Issue № 03(117) March 2022, VETERINARY SCIENCE | 0 comments

As the largest organ of the body exposed to an aggressive environment, the human skin provides physical, photochemical, antioxidant, metabolic and immune protection of the skin from ultraviolet (UV) radiation. Nevertheless, with excessive exposure to ultraviolet light, skin is at risk of developing many pathological disorders, including solar erythema, premature aging and cancer. Since the physiological function of many secondary metabolites of plants is their protection from UV radiation, they are of great interest as potential non-toxic, hypoallergenic components of sunscreen compositions that not only have photoprotective properties but also capable of affecting redox and free radical balance, as well as modulating the metabolic and immune response of the skin in the case of excessive exposure to UV radiation.

THE EFFECT OF PRENATAL STRESS ON THE BEHAVIOR OF MALE RATS

Posted in 2022, VETERINARY SCIENCE, Выпуск № 02(116) Февраль 2022 | 0 comments

In their earlier works on the study of the behavior of prenatally stressed male rats in the Suok-test model, the authors of the article drew attention to the growth of motor and research activity of animals in the light part of the test and the growth of slips and falls of prenatally stressed male rats. The purpose of this study was to clarify the effects of prenatal stress on the features of somatosensory disintegration in the behavior of male rats and to specify changes in their behavior in the light/dark system. As prenatal stress, the authors chose 3-hour immobilization from the 16th to the 19th days of pregnancy in plastic pencil cases limiting their mobility. Prenatal stress had a modifying effect on the weight of male rats (Table 1). Immature prenatally stressed male rats have a lack of body weight, while mature prenatally stressed males gained 17.5% in weight compared to control animals. The study also noted an increase of muscle strength in immature rats and its decrease in adult rats. The behavior of immature male rats underwent great changes, showing an increase in anxiety. A feature of the behavior of prenatally stressed male rats, regardless of age, was the increase in the time spent in the light part of the test, while more pronounced changes are characteristic of immature animals.

ON INFECTION INTENSITY OF PARASITIC DISEASES IN PIGS

Posted in 2022, Issue № 02(116) February 2022, VETERINARY SCIENCE | 0 comments

The article examines the intensity of invasion in diseases such as ascariasis, oesophagostomosis and trichuriasis.

As of today, the work of many farms and private farms is not efficient enough and is often unprofitable, which hinders their development. Parasitic diseases cause significant damage to pig breeding.

Ascariasis, oesophagostomosis and trichuriasis are widespread. The animals of 6-12 months of age are the most intensively affected by helminths are. The accumulation of the invasive origin is facilitated by the violation of zoohygenic conditions of pigs, the presence of a large number of reservoir hosts of nematodes (earthworms) and the absence of preventive deworming of animals.

DIAGNOSIS AND TREATMENT OF TRICHURIASIS IN PIGS

Posted in 2022, Issue № 01(115) January 2022, VETERINARY SCIENCE | 0 comments

The article deals with the diagnosis and treatment of trichuriasis in pigs. Regardless of the conditions of livestock management and the nature of their feeding, pigs always have certain parasites. Infection is facilitated by violation of the conditions of livestock housing, the absence or poor-quality implementation of therapeutic and preventive measures. In this regard, the fight against pig nematodes occupies an important place in the system of veterinary measures and the success of these measures depends on the availability of highly effective, low in toxicity and easy-to-use anthelmintics. Therefore, the therapeutic and preventive measures were developed taking into account the use of drugs such as Ivermek 1% and Fenbendazole 22.2%, which were well tolerated by animals of different ages.
