Study of genotoxicity and antigenotoxicity of the Cotinus coggygria Scop. methanol extract by Drosophila melanogaster sex-linked recessive lethal test.

The genotoxic and antigenotoxic effects of Cotinus coggygria Scop. methanol extract was investigated using the Drosophila sex-linked recessive lethal (or SLRL) test. The results presented here show that the methanol extract of Cotinus coggygria in a concentration of 5% and artificial chemical agent ethyl methanesulfonate EMS (0.75 ppm) induce recessive lethal mutations on X-chromosome on Drosophila melanogaster in all broods (I, II and III). Post-treatment with lower concentration of the methanol extract of Cotinus coggygria (2%) was effective in reducing genotoxicity ofmutagen.

[The attitude of soldiers toward military service]. / Stav vojnika prema sluzenju vojnog roka.

Due to the formation of the new state--SR Yugoslavia and transformation of armed forces as well as social-political changes which resulted in changes of fundamental social values, the aim of this study is to analyze the factors influencing the attitudes of the youths to the military service in Yugoslav army. The sample consisted of 200 adapted (group A) and 400 nonadapted (group NA) soldiers. The applied instrument was the Adjustment questionnaire. The attitude to the military service has two poles: negative included 72.5% soldiers of group NA and positive included 78% soldiers of group A. Between two poles there were 27.5% soldiers of NA and 22% soldiers of group A who were ambivalent to the military service. It is concluded that the attitude to the military service of the group A soldiers was influenced by their parents, but of the group NA was not.
