[Some aspects of the formation of the immune system organs in newborn rats born to females with chronic hepatitis].

The immune system organs formation and development was studied in 61 rat younglings born to pregnant animals with chronic toxic hepatitis. A comparative investigation permitted ascertaining that chronic heliotrine hepatitis in female rats results in an increased death rate in the progeny, the highest mortality being recordable at day 1 to 3 after birth. The surviving live younglings reveal against the background of thymus hypoplasia a significant inhibition of processes of formation of the peripheral immune organs lymphoid tissue.
