Mutation of p53 gene is one of t.he commonest genetic changes in the development of human cancer including ovary. We intvestigated the diagnostic usefulness of the demonstration of p53 gene immunoreactivity in ovarian cancers, because immunochemical demonstration of p53 immunoreactivity is inexpensive, easily controlled and can be applied in routine pathology laboratories. p53 immunoreactivity was not identified in any patients in whom there was no morphological evidence of neoplasia. ln contrast, in contrast, in 46% of patients of ovarian cancer, p53 immunoreactivity was identified. Overexpression of gene correlated with advanced stage but did not corre1ate with grade, cell type and tumor size.

A case is described of an autoimmune oophoritis that was diagnosed unexpectedly after a hysterectomy and bilateral salpingo-oophorectomy had been performed on the suspicion of ovarian cysts. The patient was a 43-year-old multiparous woman who presented with vaginal bleeding and lower abdominal pain which she had had for one month. Grossly, the ovaries were enlarged and multicystic. The cysts measured up to 3.0 cm. The major histological change was a lymphoplasmacytic infiltrate in close relation to the theca interna of developing, cystic and atretic follicles, but sparing the primordial follicles. The infiltrate increased in density with the follicular maturation and culminated against the corpus luteum. With involution of the developing follicles, the inflammatory infiltrate subsided to some extent. The proportion of the plasma cells increased with the density of the infiltrates. Immunohistochemical study of the ovarian mononuclear cell infiltrate revealed a mixture of B- and T-lymphocytes. The plasma cells were polyclonal. These histological features of the present case are typical of autoimmune oophoritis although the presence of autoantibodies and hormonal level in the patient's serum were unknown. This case may be identified as in the early active stage of autoimmune oophoritis.

OBJECTIVETo investigate the expression of cathepsin D in ovary of patients with polycystic ovarian syndrome (PCOS).

METHODSWestern blot was performed to detect the expression of cathepsin D and immunohistochemistry was used to detect the protein distribution in ovarian tissue.

RESULTSemi-quantity values of cathepsin D expression in PCOS and control group were 2.06 +/- 0.39 and 4.76 +/- 1.43 (P<0.05), respectively. Immunostaining for cathepsin D was obvious in both follicles and stromal cells, and the strongest immunostaining was seen in granulosa cells of follicles. Immunochemical study showed the protein was mainly located on the cytoplasm and cell membrane.

CONCLUSIONCathepsin D expression is down-regulated in ovaries of PCOS patients, which may provide a clue for the abnormality of follicle development in PCOS.
