Aim. Comparative measurement of concentration of lithium, circulating immune complexes and complement activity in animals’ blood and lymph in experimental anaphylactic shock and Arthus phenomenon. Methods. Experiments were conducted on 27 chinchilla rabbits in double series. The studied values of lithium, concentration of circulating immune complexes and complement activity in intact animals were used as controls. Results. On day 7 of sensibilisation before anaphylactic shock the titer of complement components in the blood decreased by 1.4 times (p <0.001) compared to parameters of intact animals, at the stage of anaphylactic shock sharp decrease of its concentration to undetermined values was observed (p <0.001). The blood concentration of circulating immune complexes increased by 4.4 times, and at the stage of anaphylactic shock (day 21) its increase by 7.1 times was observed (p <0.001). Lithium concentration decreased to 0.03 mmol/L at the stage of anaphylactic shock (p <0.001). In Arthus phenomenon at the stage of sensibilisation (day 5) the blood complement titer decreased by 1.1 times (p <0.001), during resolution period - by 10.1 times (p <0.001). The blood concentration of circulating immune complexes increased by 4.5 times (p <0.001) at the stage of sensibilisation (day 5), and at the stage of Arthus phenomenon - by 11.8 times compared to intact animals (p <0.001). Conclusion. The concentration of circulating immune complexes increases in anaphylactic and immunocomplex reactions, besides, more significantly in Arthus phenomenon (23 r.u. in anaphylactic shock versus 38.1 r.u. in Arthus phenomenon); lithium concentration in anaphylactic shock decreases by 5.2 times which is indicative of inhibitory action of this microelement in allergic reactions.
