L-arginine decreases heat shock protein 70 (marker of environmental stress) expression in kidney cells of rat fetuses during apoptosis--Late effect of Adriamycin action.

Both Adriamycin and nitric oxide (NO) cause apoptosis acting through or as free radicals inciting oxidative stress in the cell. However, in some tissues the anti-apoptotic action of NO was described, thereby the impact of NO on cell apoptosis is not finally recognized. In this study, a trial of the evaluation of exogenous NO (L-arginine) impact on apoptosis induced by Adriamycin in fetal kidney cells was undertaken.

[Tobacco smoking among adolescents-self-reported psycho-somatic health].

Studies of self-reported psychosomatic health among non-smokers and current smokers were conducted among students aged 19-20 by means of a standardised questionnaire form concerning people actively and passively smoking.

Hazard estimation for the chosen work stands in metallurgical industry.

The research has been carried out on the chosen work stands of various strenuousness level in metallurgical industry. Microclimate conditions were estimated, together with noise exposure, dust density and the exposure to the chosen chemical agents, among others carbon monoxide, nitric oxides, manganese and iron. The analysis of the resulting figures showed exceeding of the binding quotas of Wet Bulb Globe Temperature (WBGT) indicator for some stands, leading sometimes to thermal discomfort.

[Addictions in young people with different backgrounds].

The research, carried out among young people of selected groups from different environments estimated the occurrence of addictions, the degree of danger of nicotine addiction, alcoholism and pharmacomania. A questionnaire of the interview standardized into smokers and non-smokers was used among students. Evaluation of addiction to alcohol, drugs and nicotine among young people treated at the Toxicology Ward was done on the basis of clinical material of toxemias.
