[IgG anti HSV I antibodies in saliva in a drug dependent population].

It is known the presence of receptors for the morphine products on the Lymphocytes B. These receptors could have a modulator action on the production of antibodies in drug addicts. We have determined the existence of IgG anti-HSV I in saliva and serum in a heroin population. Our results show that here is not significant differences between the heroin population and the control group, when the antibodies are detected in serum. But significant differences do exist between the number of people with antibodies anti-HSV I in saliva.
