Abstract: The aim of investigation was the determination of the levels of IgE, IgG and complement activity in the blood and lymph in the experimental Arthus and Overy phenomenon. Experiments were carried out on 27 chinchilla rabbits (weight 2.5-3kg) in three series. To reproduce the Arthus phenomenon, rabbits were sensitized by subcutaneous administration of 1 ml of horse serum to the scapular region every 5 days; after the fifth injection in the injection area of horse serum the necrosis was observed. To obtain the Overy phenomenon, a resolving dose of horse serum was injected subcutaneously in a sensitized animal, and an Evans blue was introduced into the auricular vein. In this case, the injection area is colored blue. The blood necessary for the experiment was taken from the marginal auricular vein of the rabbit, and lymph – from the thoracic lymphatic duct. The levels of IgE and IgG and the activity of the complement comparatively in the blood and lymph in the experimental Arthus and Overy phenomenon were studied. The experiments were carried out on 27 rabbits of the «Chinchilla» breed in two series. The studied parameters of IgE and IgG and complement activity in blood and lymph of intact animals served as control. The results of the study showed that the level of IgG in the Arthus phenomenon increases and IgE decreases. While at the Overy phenomenon, on the contrary, the level of IgE increases and the level of IgG decreases. The titer of complement in immune complex reactions is sharply reduced; it indicates the involvement of complement with IgG elimination of the allergen.
