The localization of the cholinergic neurons in the lower thoracic segments of the spinal cord of rats was examined by a monoclonal antibody against choline acetyltransferase (ChAT). The ChAT-immunoreactive neurons were located in the intermediate as well as anterior gray matters. In the intermediate gray the highest incidence of the immunoreactive neurons(More)
The present peroxidase-antiperoxidase immunohistochemical study demonstrated that approximately 50% of the total chromaffin cells of the rat adrenal medulla exhibited NPY-like immunoreactivity. The immunoreactive material was localized in the core of the chromaffin granules as well as diffusely in the cytoplasm. By combination of immunohistochemistry with(More)
OBJECTIVE To establish an optimal adjuvant therapy for intermediate- and high-risk endometrial cancer patients, we conducted a multi-center randomized phase III trial of adjuvant pelvic radiation therapy (PRT) versus cyclophosphamide-doxorubicin-cisplatin (CAP) chemotherapy in women with endometrioid adenocarcinoma with deeper than 50% myometrial invasion.(More)
A human endometrial adenocarcinoma cell line (Ishikawa) has been found to be estrogen responsive. The growth stimulatory effects of estradiol (10(-8) M) could be clearly demonstrated when cell cultures containing the hormone were compared with the maximal cell density achieved in control cultures. The approx. 3-fold increase in cell density observed 2-3(More)
The PTEN tumor suppressor gene encodes a multifunctional phosphatase that plays an important role in inhibiting the phosphatidylinositol-3-kinase pathway and downstream functions that include activation of Akt/protein kinase B, cell survival, and cell proliferation. Enforced expression of PTEN in various cancer cell lines decreases cell proliferation(More)
The regulation of both estrogen and progesterone receptor levels in human endometrial adenocarcinoma cells of the Ishikawa line was investigated immunocytochemically by using monoclonal antibodies. Positive staining for estrogen and progesterone receptors was observed in the nuclei of Ishikawa cells. Intercellular heterogeneity in receptor content was(More)
In the endometrium, angiogenesis plays important roles not only in tumor growth but also in the menstrual cycle. The purpose of the present paper was to investigate immunohistochemically the correlation between angiogenic factor expression and angiogenic score in normal and neoplastic endometrium. Immunohistochemical staining for vascular endothelial growth(More)
A gastric choriocarcinoma cell line synthesizing human chorionic gonadotropin (HCG) was established in 1971 by Oboshi et al. and was found to possess human placental alkaline phosphatase. The present paper also deals with the relationship between the cell growth and HCG secretion and with cellular localization of HCG and human placental alkaline phosphatase(More)
Met-enkephalin-Arg-Gly-Leu-like immunoreactivity was revealed in many nerve fibers as well as in chromaffin cells in the rat adrenal medulla. The immunoreactive nerve fibers were seen among and around chromaffin cells in the forms of punctate structures or varicose processes and they were characterized by numerous small clear vesicles mixed with several(More)
