title: Relation between aryl hydrocarbon hydroxylase inducibility, serum gamma-glutamyltransferase and serum cholesterol in middle-aged smokers and non-smokers.
abstract: Aryl hydrocarbon hydroxylase (AHH) inducibility, carbon monoxide in expired air (CO), serum gammaglutamyl-transferase (GGT), and total cholesterol were compared in equal-sized, age-matched samples of healthy middle-aged males born in 1921, 1934-1936, and 1946 attending the ongoing preventive medical population program in Malmö. AHH did not differ in various age - and smoking or non-smoking groups, and there were no correlations between AHH, GGT, and cholesterol. The findings provide evidence against the recent hypothesis that low cholesterol may mediate or reflect a carcinogenic mechanism through a state of general enzyme induction in the body.
