Effects of cigarette smoking on the immune system. Follow-up studies in normal subjects after cessation of smoking.
 Hersey P, Prendergast D, Edwards A.
  "Previous reports of an association between cigarette smoking and the depression of immune function were investigated by studies of 35 subjects before, and three months after, they had ceased to smoke cigarettes. The studies included tests of natural killer cell (NK) activity against several target cells and the measurement of immunoglobulin levels in sera and saliva. Similar tests were conducted on 29 control subjects who continued to smoke. The results indicated a significant decrease in lymphocyte counts and a significant increase in NK activity against cultured melanoma cells in subjects who ceased smoking."
