    IMMUNOHISTOCHEMICAL INVESTIGATION OF ENDOMETRIAL LEUKOCYTES IN IMPLANTATION PERIOD IN RATS WITH STREPTOZOTOSIN-INDUCED DIABETES
    (Vesalius Univ Medical Publ, 2016) Nacar, Emel; Bozkurt, Yesim Akaydin; Koc, Ahmet; Nacar, Ahmet
    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.

    Background/aim: In the present study, the protective effect of erdosteine against cyclosporine-induced injury in rat liver was investigated with histological and biochemical methods. Materials and methods: Thirty-two Wistar albino male rats were randomly divided into 4 groups: control (n = 8), cyclosporine (n = 8, 20 mg kg(-1) day(-1) i.p.), cyclosporine + erdosteine (n = 8, erdosteine 12 mg kg(-1) day(-1) orally), and erdosteine (n = 8). At the end of day 12, liver tissues were removed for histological and biochemical analysis. After liver tissues were fixed in 10% buffered neutral formalin, routine histological processes were applied and tissue sections were stained with hematoxylin and eosin, periodic acid-Schiff, and elastic fiber stain methods. One hundred lobules of liver were examined for each group and evaluated statistically. The levels of malondialdehyde and glutathione peroxidase, as well as the activities of superoxide dismutase, were determined. Results: The cyclosporine group showed significant histopathological changes compared to the control. In the cyclosporine + erdosteine group, histopathological changes of hepatic damage were markedly reduced. Histological findings were supported by biochemical results. Conclusion: Erdosteine could attenuate cyclosporine-induced liver injury.
