[Cases of familial leukemia-lymphoma in Szabolcs-Szatmár-Bereg County]. / Familiáris leukaemia/lymphoma-esetek Szabolcs-Szatmár-Bereg megyében.

Nine cases of familial malignant haematologic diseases were found by authors. Demonstrating the clinical pictures and the developments of nine pairs of cases (Hodgkin's disease--non-Hodgkin's lymphoma, Hodgkin's disease--chronic lymphocytic leukaemia, non-Hodgkin's lymphoma--acute lymphoblastic leukaemia, hairy cell leukaemia--acute lymphoblastic leukaemia, chronic lymphocytic leukaemia--acute myelogenous leukaemia, non-Hodgkin's lymphoma--chronic lymphocytic leukaemia, and three times chronic lymphocytic leukaemia--chronic lymphocytic leukaemia) authors want to give data about occurrences of familial leukaemia/lymphoma in their county.

Interrelationships between the gastric secretory responses, prostaglandin E2 inhibition and serum level of immunoreactive gastrin in pylorus-ligated and antrectomized rats.

The effects of prostaglandin E2 (PGE2) have been studied on the gastric secretion and the serum level of immunoreactive gastrin in pylorus-ligated and antrectomized rats. It has been observed that: (1) a significant inhibition of gastric secretion (volume and acid output) was caused by PGE2, applied in doses of 75, 150 and 300 microgram/kg body weight, subcutaneously, in both pylorus-occluded and antrectomized rats: PGE2 inhibition of gastric secretion was more pronounced in rats with antrectomy; (2) no significant changes were found in the serum gastrin levels of both pylorus-ligated and antrectomized rats, and (3) no significant changes in serum levels of immunoreactive gastrin were produced by different doses of PGE2, in comparison with their marked inhibitory effects on gastric H+ secretion. It was concluded that there is no essential role of the immunoreactive gastrin, originated from the antral part of the stomach, neither in development of gastric hypersecretion nor in PGE2-produced inhibition on gastric secretion of the pylorus-occluded rats.
