Background. To determine the effect on the degree of dysbiosis in the organs and tissues of rats treated with high-fat diet (HFD) using fats with various fatty acid compositions.Methods. We used ordinary (high-linoleic) sunflower oil, high-oleic sunflower oil, butter, palm and coconut oils. Rats were fed with 15 % of each of the fats for 64 days. In the blood serum from v.cava and v. porta, in the liver, heart, brain, skeletal muscles and intestinal mucosa, urease activity (an indicator of bacterial insemination), lysozyme activity (a factor of non-specific immunity) were determined, and the degree of dysbiosis was calculated from the ratio of relative urease and lysozyme activities. Results. The activity of urease in the blood of v. porta increased in rats treated with HFD, and was significantly higher than in the blood of v.cava. In most of the studied tissues, urease activity increased after HFD, with the exception of rats receiving high-oleic sunflower oil (HOSO). In contrast, lysozyme activity was reduced in most tissues, with the exception of rats treated with HOSO. The degree of dysbiosis increased after HFD with the exception of rats treated with HOSO.Conclusion. HFD increases the translocation of bacteria from the intestine. The liver partially neutralizes the microflora coming from the intestines. In blood serum from v. cava and v. porta, urease activity (an indicator of bacterial contamination), lysozyme activity (nonspecific immunity factor) were determined in the liver, heart, brain, skeletal muscle and intestinal mucosa, and the degree of dysbiosis was calculated by the ratio of the relative activities of urease and lysozyme.Results. Blood urease activity v. porta was elevated in rats treated with HFD and was significantly higher than in blood v. cava. In most of the tissues studied, urease activity increased after HFD with the exception of rats treated with high oleic sunflower oil (HOSO), the development of dysbiosis in all tissues of the body. The exception is HOSO, which does not cause the development of dysbiosis and inflammation.

More than 20 % of people over the age of 50 suffer from osteoporosis.  Lipids play an important role in the pathogenesis of osteoporosis. Background. To investigate the effect of ordinary (high-linoleic) sunflower oil (OSO) on the state of periodontal bone tissue. Methods. In 5 series of experiments, determine the mineralization activity of the alveolar appendix of the mandible rats that were obtained with feed 5 or 15 percent of OSO for from 22 to 75 days. Mineralizing activity was determined by the ratio of activity of alkaline and acid phosphatase. In liver lipids (fractions of phospholipids and free fatty acids) were determined by the content of long-chain polyunsaturated fatty acids (LCPUFA) by the gas chromatographic method. Results. A decrease in mineralizing activity in OSO consumption, especially when using a feed with 15 % of OSO against a dysbiosis or metabolic syndrome. A significant (almost 10 times) is shown to reduce the content of ω-3 PUFA in fraction of phospholipids of the liver of rats receiving a diet with a content of OSO. Conclusion. Sunflower oil reduces the mineralizing activity of periodontal bone tissue by reducing the endogenous biosynthesis of ω-3 PUFA.

<p>У статті проаналізовано поширеність генералізовного пародонтиту в пацієнтів із цукровим діабетом 1 типу на тлі діабетичної кардіоміопатії порівняно з даними у практично здорових осіб з аналогічними стоматологічними захворюваннями. Доведено, що зі зростанням віку розповсюдження ГП у пацієнтів основної групи збільшується більш виражено, ніж у практично здорових людей. разом з тим, у результаті проведених досліджень визначено значення поширеності запальнодеструктивних процесів у пародонті зі збільшенням тривалості соматичного захворювання.</p>
