Оценка химического состава и энергетической ценности рационов питания высококвалифицированных спортсменов

159 highly skilled athletes were surveyed in the pre-competition period of sports training. A comparative assessment of the energy value and chemical composition of athletes diets on the basis of the questionnaire method of 24-hour (daily) reproduction of nutrition showed significant variability and dependence on the type of sports specialization of activities and gender of athletes. In particular, statistically significant (p <0.05) increase in the energy consumption value of rations in biathlonists was shown in comparison with athletes specializing in bullet shooting of various specializations of bobsleigh (overclockers and pilots) both in the male group (33.4%, 14, 8%, 31.5%), respectively, and female (33.9%, 13.8%, 41.7%), respectively. In the bobsledder of both sex groups specializing in overclocking, the energy values of rations were also statistically higher than those of athletes from the group of bullet shooting and bobsleigh pilots: by 21.7% and 19.6%, respectively, in the male group and 23.2% and 32.3%, respectively, in the female. Depending on the type of athletic activity and gender of athletes, the consumption of the main macro-intravenous animals varied significantly. In particular, the amount of protein ranged from 119.2 to 200.2 g/day in men and from 79.5 to 170.1 g/day in women; fat - 119.1-164.2 g / day for men and 84.6-148.8 g/day for women; carbohydrates - 385.1-594.6 g/day, in men and 285.5-475.6 in women.Было обследовано 159 высококвалифицированных спортсменов в предсоревновательный период спортивной подготовки. Сравнительная оценка энергетической ценности и химического состава рационов питания спортсменов на основе анкетно-опросного метода 24-часового (суточного) воспроизведения питания показала значительную вариабельность и зависимость от вида спортивной специализации и половой принадлежности спортсменов. В частности, было показано статистически достоверное (р < 0,05) увеличение показателей энергетической ценности рационов у биатлонистов по сравнению со спортсменами, специализирующимися в пулевой стрельбе, различных специализациях бобслея (разгоняющие и пилоты), как в мужской группе - 33,4%, 14,8%, 31,5% соответственно, так и женской (33,9%, 13,8%, 41,7% соответственно. У бобслеистов обеих половых групп, специализирующихся в разгоне, показатели энергетической ценности рационов также были статистически выше по сравнению с показателями спортсменов из группы пулевой стрельбы и бобслеистов-пилотов: на 21,7% и 19,6% соответственно в мужской группе и на 23,2% и 32,3% соответственно в женской. В зависимости от вида спортивной деятельности и пола спортсменов потребление основных макронутриентов варьировало в значительных пределах. В частности, количество белка составляло от 119,2 до 200,2 г/сут у мужчин и от 79,5 до 170,1 г/сут у женщин; жира - 119,1-164,2 г/сут у мужчин и 84,6-148,8 г/сут у женщин; углеводов - 385,1-594,6 г/сут, у мужчин и 285,5-475,6 у женщин

Immunohistochemical features of breast fibroadenomas

9 breast fibroadenomas from females of different age who had a familial history of breast cancer were immunohistochemically studied. Having the same histological structure, the tumors differed in the expression of steroid hormone receptors, in the values of proliferation marker Ki-67 and oncomarker p53. It is concluded that the study of fibroadenoma may reveal breast carcinoma risk groups

Endometrial morphological and immunohistochemical features in females with primary and secondary infertility

Endometrial scrapes and biopsy specimens from 47 females with primary and secondary infertility were studied by histological and immnohistological (estrogen and progesterone receptors, Ki67) methods. Endometrial abnormalities, such as luteal phase defect, hyperplasia, endometrial polyps, and chronic endometritis, were detected in all the patients. There were considerable changes in the expression of estrogen and progesterone receptors and impaired endometrial proliferative processes. There was no clear correlation of immunohistochemical parameters with blood hormone levels in both primary and secondary infertility. The findings may be of significance in choosing the schemes of assisted procreation technologies
