[Experimental study of immune reactivity in Swiss mice due to topical administration of three textile dyes]. / Studiu experimental pe soareci swiss privind modul de reactie a sistemului imunitar în urma administrarii topice a trei coloranti reactivi textili.

UNLABELLED: Reactive Red 183, Reactive Red 2 and Reactive Blue 204 (red dye, green dye and blue dye) are three reactive dyes frequently used in textile industry. In some atmospheric conditions ( high temperature, perspiration, pH values, UV/IR radiations), some quantities of these hydrolyzed dyes, could pass from textile clothes directly into the human skin. MATERIAL AND METHOD: There were used 4 groups of white Swiss mice (with similar weight and number of both sexes), control group and 3 groups, treated once daily with a retro-auricular application of different reactive dyes. After 14 days of treatment, blood samples were taken from retro-orbitary plexus to assess leukocyte count, phagocytic capacity of peripheral neutrophils, serum opsonic capacity, phagocyte capacity and bactericidal capacity of peritoneal macrophages, splenic T lymphocytes with rossetting capacity and spleen cells forming Jerne plaques. The retro-acuricular and latero-cervical nodes were weighted. RESULTS: Red dye did not influence the weight of the studied nodes, but determined statistically significant modifications on non-specific immune system parameters. Blue and grena dyes determined modifications of weight especially of retroauricular nodes. Grena dye determined important effects of non-specific immune system parameters (serum opsonic capacity, phagocyte capacity and bactericidal capacity of peritoneal macrophages). The blue dye did not determine a biological response. CONCLUSION: Red and green dye determined important effects on non-specific immune system parameters.

[Dietary survey in an obese population]. / Ancheta alimentara într-o populatie obeza.

The body mass index (BMI) shows a rate of 17.4% patients suffering from first degree fatness and 56.5% from second degree fatness. The frequency of the illness increases with age, the differences established being statistically important for a p of 0.001. 45.6% persons were diagnosed with HTA, with differences statistically important at a p of 0.01, so the number of cases increases with age. The same situation is to be found in cardiovascular illnesses (angina pectoris, ischaemic cardiopathy). The high level of cholesterol is more frequent at older people, and still the differences established are statistically not significant. In these conditions, the diet must be adapted to the patient's condition. A comparative study was made on groups of age, using the following groups of food: cereal derivatives, vegetables, fruits, dairy product, meat, fish. In most of the cases, the differences established are statistically not significant. So, even if the diagnosis is known, the patient doesn't give up his eating habits.
