[Immunohistochemical localization of XXXX in @entity189 of the ovary].

@entity172 @entity722 @entity5 @entity189 @entity53 @entity420 @entity4348
@entity722 derived from sexcord-stromal cells are thought to be generally @entity172 producing @entity5 . However recent reports show that these common @entity5 , @entity420 and @entity5 , are capable of @entity172 activity. We have studied the production of @entity172 in common epithelial malignant @entity5 of the ovary. Two cases of @entity189 , five cases of @entity189 and two cases of @entity4348 were examined for the presence of @entity53 using an indirect immunoperoxidase method. The results were as follows: In all @entity5 , one case of @entity189 , four cases of @entity189 and one case of @entity4348 had a positive immunoperoxidase reaction. The incidence of positive reaction showed that @entity189 were more numerous than others. In positive cases, @entity53 localization was recognized in the epithelial cell of mucinous @entity5 to various degrees, but there was no @entity53 localization in admixed goblet like cells. In @entity5 and @entity4348 also @entity53 localization was seen in the cytoplasm. Stromal cells tended to be more weakly positive than epithelial cells. No @entity53 localization was detected in any of the spindle cells or fibrinous connective tissues. These results suggest that some common epithelial malignant @entity5 of the ovary have @entity172 activity and @entity53 is produced not only in stromal cells but also in epithelial cells.
