[Immunohistochemical study of XXXX of the tissue and cell levels in @entity420 ].

@entity1204 @entity420 @entity787
Immunohistochemical staining was performed for @entity787 ( @entity787 ) in tissues taken from 41 cases of cervical and 67 cases of @entity1204 . Utilizing this method, smear specimens from 21 cases with cervical and 25 cases with @entity1204 were investigated at the cell level. THE RESULTS: 1) The investigation at the tissue level indicated that @entity787 staining was positive in 80% of cases of cervical @entity420 . On the other hand, the positive rate was as low as 55% of the @entity1204 cases. It further declined to 35% when limited to pure @entity420 without squamous elements. In addition, a difference was recognized between the cervical and endometrial groups in their localization. It was apparent that while even the cytoplasm in most of the cervical @entity420 appeared to be markedly stained, such a tendency was observed and was weak in only a part of the cell membrane in the @entity1204 cases. 2) The studies with smear specimens indicated that while 57% (13/21) of the cervical @entity420 cases were @entity787 positive, only 12% (3/25) were positive in @entity1204 cases. Therefore, a difference was recognized between the two at the cell level in their @entity787 staining characteristics. 3) Our observation revealed that @entity787 was more prominent in the poorly differentiated type than in the well differentiated one, in both cervical and @entity1204 . This seems to indicate a relationship between the histological differentiation and production of @entity787 . On the basis of the above findings, it was inferred that although both cervical and @entity1204 occur in the common M  llerian duct organ, they might have different biological characteristics.(ABSTRACT TRUNCATED AT 250 WORDS)
