Pooled analysis of studies on DNA adducts and dietary vitamins.

Objectives: There is some evidence that dietary components that are rich in antioxidant and vitamins are inversely associated with DNA adduct levels induced by environmental carcinogens such as polycyclic aromatic hydrocarbons, although the epidemiologic data are inconsistent. This study addresses the association between vitamins, DNA adducts and smoking.

Methods: A combined analysis of individual data on the association between bulky DNA adducts and dietary vitamins was conducted.

Initial results of Central European Immunophenotyping Quality Control Program (CEQUAL).

The new Quality Control Program in Immunophenotyping for Central Europe (CEQUAL) was created in 1993. Its first formal send-around proficiency exercise, consisting of a stained stabilised preparation of leukocytes, took place in November 1993. Forty-one laboratories from Slovakia, Poland, Hungary, and the Czech Republic participated.

Experimental studies of some microrheological factors in serious brain ischemia after stobadine pretreatment.

Serious brain ischemia was induced by occlusion of cerebral arteries in dogs. The occlusion time was 7 min. The blood was collected at various intervals of reperfusion (5, 60, 180, 240 min and 24 h).
