Analysis of the physical development of youth and the state of its health.

OBJECTIVE: Introduction: The sharp deterioration in the physical development of the younger generation is worrying. The morbidity of youth has increased by 29.9% compared with the last century. More than 33% of boys and girls, among first-year students with chronic diseases. The aim: Assessing the state of the students' body by examining the results of a survey among the second- and third-year students of the university using a specially designed questionnaire. PATIENTS AND METHODS: Materials and methods: The material on the assessment of the state of health and the characteristics of the organism has been processed by studying the results of a survey of young men and women aged 20-23, obtained on the basis of using the developed questionnaire. RESULTS: Results: Physical development has been studied in accordance with the state of health of the students, as well as a thorough study of a number of criteria: diseases of the musculoskeletal system were 37.1%, 49.7% and 43.45 among boys aged 20, 22 and 23 and respectively 33.3 %, 38.6% and 47.7% among girls in their 20s, 22s and 23s. The morbidity of eye was 18.0%, 3.8% and 9.9% among boys aged 20, 22 and 23 years and 17.7%, 17.1% and 7.7% among girls aged 20, 22 and 23 years. CONCLUSION: Conclusions: In the structure of morbidities are diseases of the musculoskeletal system, diseases of the nervous system and the organ of vision. Correlation of the characteristics of the level of students' health and their physical development have indicators on the level of educational adaptation and the number of diseases.

Comparative histological structure of the gastrointestinal mucosa in human and white rat: a bibliographic analysis.

OBJECTIVE: Introduction: According to numerous domestic and foreign researchers, morphofunctional structure of the digestive system of humans and rats have much in common, therefore, rats are used as the laboratory animals during the experiments. The aim of the paper was the comparative study of the histological structure of the gastrointestinal mucosa in human and white rat through the bibliographic analysis of the publications. PATIENTS AND METHODS: Materials and methods: The material for the investigation was current publications on the study of the histological structure of the intestine mucosa in human and white rat by analyzing, synthesizing and generalizing the resulting data. RESULTS: Review and discussion: Histologically, the gastrointestinal mucosa in white rat is similar to the human one. The gastrointestinal mucosa in white rats (with the exception of the generic difference in the structure of the stomach and the caecum), in its histological structure, is quite similar to the human one, to be studied in the experimental simulation of the specific lesions of the digestive system.

General comparative anatomy of human and white rat digestive systems: a bibliographic analysis.

OBJECTIVE: Introduction: The gastrointestinal tract of humans has much in common with most species of laboratory animals, particularly at the level of microscopic study. White rats are widely used in the experiments to determine the influence of the environmental factors on the human. The aim: Study the general comparative anatomy of the digestive system of the human and the white rat through the bibliographic analysis of the publications. PATIENTS AND METHODS: Materials and methods: Current scientific publications on the study of the human and the white rat gastrointestinal tract morphology were used as the material for the research by analyzing, synthesizing and generalizing the information obtained. RESULTS: Review and conclusions: Generally, the anatomical structure of the white rat digestive system is similar to the human one. Phylogenetically, the digestive systems of humans and rats are the homologous functional system that are much in common regarding the structure and functions of the organs, the significance of which is in the perception, mechanical and chemical (enzymatic) digestion and absorption of the nutrients into the body.
