Abstract
The research of immunotoxicity of extended-release form of Afobazol was conducted on male CBA, C57BL/6 and F1 hybrids (CBA×C57BL/6) mice. Afobazol was administered per os for 14 days in doses of 12 mg/kg and 120 mg/kg. Control group received a placebo. Weight of thymus, spleen and popliteal lymph nodes was not affected by the extended-release form of Afobazol in doses of 12 mg/kg and 120 mg/kg in F1 hybrids (CBA×C57BL/6) mice compared to the control group (p> 0.05). Cellularity of thymus was significantly increased by the extended-release form of Afobazol in dose of 12 mg/kg (p< 0.01 vs control group). Administration of the extended-release form of Afobazol in doses of 12 mg/kg and 120 mg/kg decreased spontaneous chemiluminescence activity of peripheral blood lymphocytes in 2.0 and 2.2 times, in dose of 120 mg/kg level integral chemiluminescence response S was decreased in 2.4 times (p< 0.05 vs control group). Phagocytic activity of peritoneal macrophages and antibody production in F1 hybrids (CBA×C57BL/6) mice were not affected by administration of the extended-release form of Afobazol in doses of 12 mg/kg and 120 mg/kg (p > 0.05 vs control group). 14 days of the extended-release form of Afobazol in doses of 12 mg/kg and 120 mg/kg did not cause any significant change to intensity of delayed-type hypersensitivity reactions (p> 0.05 vs control group). The results of the study allow us to conclude that administration of the extended-release form Afobazol in the range of studied doses does not induce immunotoxicity.

Summary
Проведено исследование иммунотоксичности пролонгированной формы препарата Афобазол на самцах мышей линий СВА, C57BL/6, гибридах F1(CBA×С57BL/6). При оценке иммунотоксического действия Афобазол вводили мышам опытных групп перорально 14 дней в дозах 12 мг/кг и 120 мг/кг. Введение пролонгированной формы препарата Афобазол в дозах 12 и 120 мг/кг значимо снижало уровни спонтанной хемилюминесценции в 2,0 и 2,2 раза, а в дозе 120 мг/кг значимо (p < 0,05) снижало интегральный показатель хемилюминесценции S в 2,4 раза по сравнению с контрольной группой, получавшей плацебо. Введение пролонгированной формы препарата Афобазол перорально 14 дней в дозах 12 мг/кг и 120 мг/кг мышам линий СВА и C57BL/6 не вызывало значимого влияния на антителообразование по сравнению с данными контрольных групп. Результаты проведённого исследования иммунотоксичности пролонгированной формы препарата Афобазол позволяют заключить, что введение Афобазола в диапазоне изученных доз не оказывает иммунотоксического действия.
