title: [The use of taktivin in experimental apical periodontitis exacerbated by a secondary immunodeficiency state].
abstract: Apical periodontitis was simulated in 100 white rats with secondary immunodeficiency induced by a single total x-ray irradiation with the RUM [correction of PYM]-17 device. Nonspecific resistance of the rat body was assessed from the neutrophilic phagocytic activity, serum bactericidal activity, lysozyme and complement levels. These parameters were found reduced in the experimental animals; x-ray examinations revealed changes round the dental root apices. Daily injections of tactivin for 10 days in a dose 2-5 mg/kg b.m. resulted in elevation of the nonspecific resistance parameters, and the x-ray picture in this group of animals was the same as in intact controls; therefore, tactivin normalized the immunity system status and indirectly improved the clinical course of apical periodontitis.
