ABSTRACT
We studied the status of estrogen(ER) and progesterone(PR) receptors in meningiomas removed from 32 patients, using immunoperoxidase(IP) assays. PR were detected in 72% of the cases & ER were detected in 31%. The possible correlation between age, sex, histological type, ploidy pattern and proliferation index values with steroid receptor activity were discussed. The date suggest that the majority of meningiomas contain high affinity receptors for progesterone, that estrogen receptors are present in only a few meningiomas.

Adult Schistosoma japonicum worms and Oncomelania hupensis hupensis tissue sections were employed as antigens in the studies of anti-O.h.hupensis rabbit serum and anti-S.japonicum adult worm rabbit serum by indirect immunaperoxidase assay.The result indicated that the most prominent peroxidase reaction was presented in the adult worm sections and the head-foot and liver sections of O.h,hupensis.These suggested the possible presence of antigenic homology between Schistosoma japonicum and Oncomelania hupensis hupensis.(Figs.1-7)
