title: The influence of long-term administration of Tołpa Peat Preparation on immune reactivity in mice. III. The effect on primary humoral response to sheep erythrocytes.
abstract: Tołpa Peat Preparation (TPP) was administered to mice in daily doses of 1, 10 and 50 mg.kg-1 for 3, 5, 7, 9 or 12 consecutive weeks. After each of the above mentioned periods the primary response to sheep erythrocytes (SRBC) was examined by determination of the percentage of splenocytes forming E rosettes, the number of splenocytes producing anti-SRBC haemolysins of 19S and 7S type, and the level of serum haemagglutinins to SRBC (19S + 7S and 7S types). The effect of enhanced humoral response by TPP was observed in mice immunized with SRBC. This effect depended, first of all on TPP does but also on the duration of time TPP administration. The stimulating effect on the humoral response occurred after the daily dose of 1 mg.kg-1 during 12 weeks. On the other hand, the daily doses of 10 or 50 times higher enhanced the humoral response only during the first 5-7 weeks of TPP administration. Longer administration of TPP in these doses caused disappearance of this effect or reduction of the response to SRBC.
