The aim of the study was to find out predispositions to eating disorders (ED) such as anorexia and bulimia nervosa in girls between 14-19 years, going to grammar or secondary school. 189 girls were to answer questions of Eating Attitude Test 26 (EAT26) and fill a questionnaire prepared by authors of the study. Both questionnaires were anonymous. 19 girls (10,1%) attained 20 and more points and were qualified as EAT26+ what means predispositions to eating disorders. Body Mass Index (BMI) was used to estimate a state of nutrition. In the group EAT26+ most of the girls (57,9%) presented proper weight-height proportions.
Angiogenesis and VEGF play a major role in many repair processes such as healing of gastric ulceration.The present study was undertaken to assess the dynamics of changes in VEGF expression and angiogenesis in stress-induced gastric ulcers in rats. Acute gastric ulceration was induced using a water-immersion and restraint stress method. The VEGF expression, angiogenesis, size of area and depth of ulcers in gastric speciments were evaluated. The study shows that as early as one day after the development of ulcers there is a significant increase in both the expression of the VEGF protein and the number of newly formed microvessels, while an abrupt decrease in VEGF expression, observed on the fifth day, results in a decreased intensity of angiogenesis. Moreover, it has been demonstrated that the increase in VEGF expression and angiogenesis is accompanied by a reduction in the size of area and depth of stress-induced ulcers in rats. Six days after ulcer development both VEGF expression and angiogenesis return to normal levels.
The aim of the study was to evaluate prevalence and risk factors of sight defects in students of dentistry using a questionnaire and base-line eye examination. Myopia was observed in 44 (50,00 %) students, hypermetropia in 3 (3,41%) students. None of spherical refraction defects was observed in 41 (46,59%) examined. There were 34 (77,27%) women and 10 (22,73%) men in the group with the diagnosed myopia. Observed myopia was qualified as low or medium grade. The low grade myopia was diagnosed in 38 students (86,36%) and the medium grade in 6 cases (13,64%). In 11 (25,00%) cases it was noticed for the first time. The statistical analysis indicated familial occurance of refraction defect in subjects.
