The influence of long-term administration of Tołpa Peat Preparation on immune reactivity in mice. I. Morphological changes in the thymus.
In experiment I BALB/c 200 mice were given in drinking water the TPP (Tołpa Peat Preparation) in daily doses of 1, 10 and 50 mg/kg over the period of 3, 5, 7, 9 and 12 weeks. In experiment II before the administration of TPP (as in experiment I) mice were immunized with a single dose i.p. administration of 0.2 cm3 of a 10% suspension of sheep erythrocytes (SRBC), i.e. 4 x 10(8) cells. Histopathological and ultrastructural studies have shown that TPP in all three doses causes morphological changes characteristic of thymus activity stimulation. However, the doses of 10 and 50 mg/kg administered longer than 7 weeks caused retrograde changes that did not occur after administration of 1 mg/kg of TPP. Morphological changes in the thymus of immunized and non-immunized mice simultaneously receiving TPP were similar.
