role of hair in chronic lead toxicity

The concentration of lead was determined in hair and blood of 90 exposed workers and 100 non exposed workers. Urinary 8 amino levulenic acid was also determined in both groups. Hair was obtained from the scalp, chest and pubic region. The mean scalp hair lead concentrations weie 48.6, 18.2, ug/gm of hair in both exposed and non exposed workers respectively. The mean chest hair lead concentrations were 45.4, 14.3 and that for pubic hair leach concentrations were 40.5, 9.4 in the same groups. Hair lead concentration was highly correlated with blood lead concentration, but there is no significant correlation with urinary 8 amino levulinic acid

Effects of cigarette smoking on serum lipids and lipoproteins patterns on adult and middle age Egyptians

196 volunteers were examined to dertermine the effect of cigaratte smoking on the cardiovascular system. Special reference was given to the role played by cigarette smoking in increasing risk of CHD. It has been found that there is a significant increase in the Co-Hb% in smokers with a positive correlation to the number of cigarettes smoked / day. The role played by nicotine and Co was discussed. It has been also found that cigarette smoking has an atherogenic effect with increased levels of triglyceride, LDC and Apo-B lipoprotcins, a decrease in the HDC and Apo-A lipoproteins. The value of Apo-B / Apo-A ratio as a better index for CHD predection was discussed
