The localization of CD3, CD79a, CD68 and S100 protein immunoreactive cells in hemal nodes of Saanen goat (Capra hircus).

We investigated the structure of hemal nodes in Saanen goats using immunohistochemical staining. We examined the distribution of CD3 positive T lymphocytes, CD79a positive B lymphocytes, CD68 positive macrophages and S100 protein positive follicular dendritic cells. Hemal nodes of six healty adult female goats were used. Hemal nodes were removed from the thoracic and abdominal cavities. The oval to round hemal nodes were observed especially between the abdominal aorta and vena cava, and near the kidneys and adrenal glands. Tissue sections were stained with Crossmon's modified triple stain to demonstrate general histological structure. The avidin-biotin-peroxidase technique using anti-CD3, anti-CD79a, anti-CD68 and anti-S100 primary antibodies was used for immunohistochemistry. Many CD3 positive T lymphocytes were found in the germinal center of the lymph follicles and in the lymphatic cords of hemal nodes; CD3 positive cells also were observed in the sinuses. CD79a and CD68 positive cells were found at the germinal center of the lymph follicles. In the lymph follicles near the subcapsular sinuses, CD79a and CD68 positive cells were found especially in e areas bordering the mantle zone. S100 positive cells were found in the lymph follicles, lymphatic cords and sinuses.

Immunohistochemical investigation of endometrial leukocytes in implantation period in rats with streptozotosin-induced diabetes.

Our first aim was to determine the total leukocyte profile in implantation. Second aim was to detect the changes in uterine leukocyte profile in diabetes, a common accompanying disease. For this purpose 4 groups are formed with Wistar albino rats weighing 250-300 g. Two of the groups were non-diabetic and two of them were diabetic. One of the diabetic and one of the non-diabetic groups were left pregnant. Then uterus tissues of pregnant animals were removed in the 5th and 7th days of pregnancy together with tissues of other two non-pregnant groups. Tissues were analyzed immunohistochemically with antibodies CD45, CD3, CD4, CD8, CD56, CD68 and CD79a. It was revealed that pregnancy increased immune staining of CD68, CD3, CD45 and CD56 in endometrium. In addition it was observed that immune staining density of CD68, CD45 and CD56 decreased in diabetes. In the histopathological examination, significant degeneration was detected in the endometrium of diabetic rats. Diabetes could decrease leukocyte proportions in decidua in early pregnancy periods. Therefore immune cell therapies could be administrated in diabetes related problems of pregnancy.

Histological and immunohistochemical studies of the structure of lymph nodes in Kilis goats.

Ten healthy adult Kilis goat mesenteric lymph nodes were used to examine the general structure of lymph nodes, lymphocytes, plasma cells, reticular cells and reticular fibers using histological methods. We also detected T lymphocytes using anti-CD3 [SP7], anti-CD4 [74-12-4], mouse anti-bovine CD4 [CC30] and mouse anti-bovine CD8 [CC63] monoclonal antibodies (mAb); and B lymphocytes using anti-CD79a [HM57] mAb, macrophages using anti-macrophage [MAC387] mAb and follicular dendritic cells using anti-S100 polyclonal antibody (pAb). The distribution of these cells also was studied. Although the primer antibodies we used for CD3, CD8, CD79a, MAC387 and S100 worked well, the primer antibodies for CD4 were ineffective for paraffin embedded goat lymph nodes.
