Analysis of the Efficiency of Different Antituberculous Drugs and Approaches to Treat BCG-Induced Granulomatosis in Mice and Abundance and Localization of Mycobacterium tuberculosis in the Liver.

Abstract
In 3 months after infection with Mycobacterium tuberculosis (MBT) from BCG vaccine, male BALB/с mice received intraperitoneal injections of isonicotinic acid hydrazide, dextrazide, or liposome-encapsulated dextrazide, or inhalation of liposome-encapsulated dextrazide 2 times a week for 6 months. In 6 months, no MBT were detected in macrophages outside granulomas in treated mice. Macrophages containing MBT can incorporate into granulomas and leave them after suppression of MBT persistence. Liposome-encapsulated dextrazide showed the maximum therapeutic efficiency: the total MBT level in granuloma macrophages and volume density of destruction foci in the liver parenchyma decreased by 5.1 and 5.3 times, respectively, in comparison with the corresponding parameters in mice treated with isonicotinic acid hydrazide. Inhalations of liposome-encapsulated dextrazide prevented the destructive processes in liver granulomas due to macrophage migration from granulomas, which reduced granuloma sizes and destructive potential of granuloma lysosomes and therefore improved their diffusion-dependent trophics.
