    Effect of Moringa oleifera on serum YKL-40 level: In vivo rat periodontitis model
    (De Gruyter Poland Sp Z O O, 2023) Kocabas, Rahim; Yarkac, Fatma Ucan; Karabulut, Ercan; Keles, Mert
    Periodontitis is a chronic inflammatory disease that destroys the bones and soft tissues that support the tooth as a result of inflammatory reactions. YKL-40 is an inflammatory marker associated with inflammation and is also associated with periodontal diseases. Moringa oleifera (MO) is a plant rich in high nutritional values, minerals, vitamins, and other essential phytochemicals. The aim of this study was to investigate the effect of MO administration on serum YKL-40 levels in an experimental periodontitis model. In the study, a total number of 24 female Wistar albino rats, which were 4-5 months old with a body weight of 275 +/- 25 g, were used. Animals were divided into three groups. 1st group: Control (n = 8), 2nd group: periodontitis group (PG) (n = 8), 3rd group: Periodontitis group (PG + MO) with an additional 200 mg/kg/4 weeks MO (n = 8). In the PG and PG + MO were formed experimental periodontitis model. Compared to the PG, the decrease in the interleukin-6 (IL-6) and YKL-40 values in the PG + MO (p < 0.05, p < 0.05) was found to be significant in terms of statistical evaluation. As a result, MO decreased YKL-40 levels in the experimental periodontitis model. Although further research is needed, drugs containing MO can be used in the treatment of periodontal diseases.

    The effects of orchiectomy and steroid on fertility in experimental testicular atrophy
    (Korean Soc Reproductive Medicine, 2023) Yurtcu, Muslim; Kozacioglu, Sumeyye; Kocabas, Rahim
    Objective: Despite our understanding of Sertoli cell function and the state of spermatogenesis, the underlying mechanisms remain unclear. This study was conducted to compare the effects of orchiectomy and steroid treatment on fertility in testicular atrophy occurring after testic-ular torsion.Methods: Thirty-three rats were divided into four groups. The atrophy, orchiectomy, and atrophy-steroid groups each contained nine rats, while the control group contained six. The left testes were rotated 720o, and atrophy was observed. In the atrophy-steroid rats, orchiectomy was performed after atrophy, and 1 mg/kg steroid was injected. Each male rat was housed with five female rats for 6 days. The fertility of the male rats was evaluated based on the pregnancy of the female rats. Left and right orchiectomies were performed to determine the tissue Johnsen score (JS) and the serum inhibin B (IB) level.Results: JS values were significantly lower in the atrophy, orchiectomy, and atrophy-steroid groups than in the control group (p<0.05), while no significant difference was observed in JS between the atrophy and orchiectomy groups (p>0.05). Similarly, no significant differences in IB level or fertility percentage were found between the atrophy and orchiectomy rats (p>0.05).Conclusion: In unilateral testicular atrophy, which can occur in the prepubertal period due to various causes, orchiectomy does not appear to benefit fertility, as indicated by IB, JS, and the fertility percentage.

    The effects of trans-9 18:1 octadecenoic acid isomer on levels of sICAM-1, sVICAM-1 and IGF-1
    (Walter De Gruyter Gmbh, 2011) Akoz, Mehmet; Kocabas, Rahim; Topcu, Cemile; Gurbilek, Mehmet
    Objective: The effects of trans-9 18: 1 octadecenoic acid isomer from the fatty acid isomers taken with diet on soluble cell adhesion molecules (sICAM-1: Soluble intercellular adhesion molecule-1 and sVCAM-1: Soluble vascular cell adhesion molecule-1) and insulin like growth factor-1 (IGF-1) levels were investigated on rats. Method: The rats which were fed for two weeks by the same diet were separated into experimental and control groups. Fifty mg/day trans-9 18: 1 octadecenoic acid isomer was added to the diet of experimental group for 10 days. Following the completion of special diet, fatty acid composition in both groups was studied by gas chromatography analysis. Results: Trans-9 18: 1 fatty acid level in the experimental group was higher than control group (p<0.01). The soluble cell adhesion molecules (sICAM-1 and sVCAM-1) increased (p<0.01) and IGF-1 levels decreased (p<0.05) in rats fed with trans-9 18: 1 octadecenoic acid. Conclusion: Our results indicate that, high levels of dietary trans fatty acid isomers are a factor in the increasing of cell adhesion molecules (sICAM-1, sVCAM-1) levels and decreasing of IGF-1 levels. Hence, measurement of these parameters may be beneficial in patients with coronary artery disease and atherosclerosis, as well as in other pathological cases. We believe that these parameters may also be useful for early diagnosis.

    Role of thiol-disulfide hemostasis in early diagnosis of acute mesentery ischemia: An experimental study
    (Turkish Assoc Trauma Emergency Surgery, 2022) Yildirim, Mehmet Aykut; Kocabas, Rahim; Kilinc, Ibrahim; Simsek, Gurcan; Senturk, Mustafa; Cakir, Murat; Belviranli, Metin
    BACKGROUND: Acute mesenteric ischemia (AMI) is a rarely observed acute abdominal disease that may be mortal and is difficult to diagnose early. The aim of our study is to assess the role of Thiol-Disulphide Haemostasis (TDH), a new method for AMI which still has no specific biochemical markers for early diagnosis, and to assess it together with Ischemia-Modified Albumin (IMA) which METHODS: The study included 32 Wistar albino rats in four groups. The 1st group (n=8) was the control group, 2nd group (n=8) was the sham group, 3rd group (n=8) had 3 h of arterial mesentery ischemia and the 4th group (n=8) had 6 h of arterial mesentery ischemia. RESULTS: In the 3rd and 6th h, serum total thiol and native thiol values significantly reduced (p<0.001), while serum disulfide, IMA, and lactate values clearly increased (p<0.001). Serum thiol values were observed to reduce from the 1st h. CONCLUSION: TDH changes in the early period of AMI. The TDH parameters can be used with IMA as diagnostic parameters for patients with suspected AMI in the early period.
