Argyrophil Cells in Normal Human Uterine Cervix
Introduction: Argyrophil cells are neuroendocrine cells which react with silver stain resulting in brown or black coloration with the help of an external reducer. Argyrophil cells occur rarely in the normal human uterine cervix but are found in a variety of invasive tumors arising in the cervix. Methods and Results: About 317 normal human uterine cervices were stained with Grimelius argyrophili...
متن کاملArgyrophil cells in normal, hyperplastic, and neoplastic endometrium.
Scanty argyrophil cells are present in a substantial proportion of normal endometria, particularly during the secretory stage of the cycle. Argyrophil cells are also present in the various types of hyperplastic endometria and are found in more than half of endometrial adenocarcinomas. In some endometrial neoplasms they are present in abundance, but tumours rich in such cells do not have any fea...
متن کاملPreparatory studies of composite mesenchymal stem cell islets for application in intraportal islet transplantation
BACKGROUND Low engraftment and adverse immune reactions hamper the success rate of clinical islet transplantation. In this study, we investigated the capacity of human mesenchymal stem cells (MSCs) to adhere to human islets of Langerhans and their effects in immune modulation and during blood interactions in vitro. METHODS Composite MSC-islets were formed by suspension co-culture, and the phe...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Granulosa Cell – Stromal Tumors: An Immunohistochemical Study Including Comparison of Calretinin and Inhibin
Background and Objective: Histopathological evaluation of granulosa cell tumors (GCT) of the ovary may be confused morphologically with a wide variety of the tumors. Immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. Although it has been suggested that inhibin can be a sensitive marker for GCT, it maybe had negative results in some cases. In addition, cal...
