    (Taylor & Francis Ltd, 2024) Kaplan, Selcuk; Turk, Bilge Aydin; Elibol, Ebru; Ozbey, Guerkan; Ekinci, Tekin
    The present study aimed to investigate the histopathological effects of obstetric gel (OG) on vaginal tissue. In this study, 21 female Wistar albino rats were divided into three groups, comprising seven animals in each group. The first group (group 1) was the control group, the second group (group 2) was the physiological saline (PS) group, and the third group (group 3) was the OG group. In group 1, dilatation was performed using Hegar dilators from Hegar 5 to Hegar 10 without any vaginal application. In group 2, the vagina was washed with a PS-filled applicator. In group 3, the vagina was washed with an OG-filled applicator and Hegar dilators were used to achieve vaginal dilatation. In the group of OG-applied rats, there was an increase in mast cell infiltration, tissue epithelial thickness, and fibrillin-1 levels of the mucosa in the vaginal tissue. The present study is the first to investigate the histopathological effects of OG used for vaginal tissue dilatation in rats. OGs have no early effectiveness in preventing the damage caused by compression of the vaginal wall; however, OGs may have a protective effect against pelvic floor pathologies.

    The role of toll-like receptor 4 in the development of endometriosis and the benefits of trastuzumab in the treatment of endometriosis: a rat model
    (Taylor & Francis Ltd, 2025) Korun, Zeynep Ece Utkan; Kirici, Pinar; Elibol, Ebru; Kaplan, Selcuk; Karacor, Talip
    We aimed to investigate TLR-4 receptor activity in the development of endometriosis and the effect of trastuzumab in experimentally induced endometriotic tissue via TLR-4 in this study. Twenty-eight female Wistar-Albino rats were divided into four groups: Group 1 (Control Group), Group 2 (Endometriosis Group), Group 3 (Endometriosis + Trastuzumab Group), and Group 4 (Trastuzumab Group). All animal tissue samples were collected. Histopathological, immunohistochemical, and biochemical analyses were performed. In histopathological analysis, there was a significant difference between Group 2 and other groups in terms of connective tissue edema, inflammation, hemorrhage, epithelial damage, and mast cell density. In immunohistochemical analysis with TLR-4, Group 2 exhibited strong staining. In biochemical analysis, it was found that there was a highly significant difference between Group 2 and Group 1 considering the Malondialdehyde (MDA) levels in plasma samples. There was no significant difference in terms of the MDA levels among other groups. Considering the glutathione levels in the plasma samples, it was found that there was a highly significant difference between Group 2 and Groups 3 and 4. Trastuzumab may play a role in the treatment of histopathological damage and fibrosis in experimentally induced endometriotic implants by showing anti-inflammatory and antiproliferative activity.
