    Effectiveness of Boric Acid in Sepsis in Rats With Cecal Perforation
    (Springer Nature, 2025) Kurtipek, Ali Can; Dursun, Ali Dogan; Yigman, Zeynep; Ozdemir, Cagri; Kucuk, Aysegul; Gonullu, Ugur; Arslan, Mustafa
    Introduction and AimSepsis is a systemic inflammatory response that develops in the host against microorganisms, which results in end-organ damage. Boric acid (BA) has been shown to have immune modulatory effects in vitro and in animal studies. The aim of the study is to investigate the effects of high dose BA on lung and kidney tissues in rats with sepsis induced by the CLP method.Method28 rats were randomly divided into four groups: Group C (control group), Group BA, Group CLP (cecal ligation and puncture), and Group CLP + BA. Cecum was ligated below the ileocecal valve and punctured. BA was administered to the treatment groups at an intraperitoneal dose of 200 mg/kg, and at the end of 24 h, lung and kidney tissue samples were collected and evaluated for biochemical and histopathological parameters.ResultsHistopathologically, in kidney tissue, CLP + BA group showed significantly less peritubular capillary dilatation and brush border loss in the proximal tubule epithelium compared to the CLP group. In lung tissue, CLP + BA group had significantly less alveolar wall thickening compared to the CLP group. Biochemical analyses indicated that BA administration reduced oxidative stress in both renal and lung tissues.ConclusionWe found that intraperitoneal administration of high dose boric acid partially ameliorated the tissue damage in rats subjected to CLP induced sepsis. Further studies are needed regarding the dosage and application at different time points.

    Protective Effects of Hydrogen Rich Saline Solution in Rats With Experimental Myocardial Ischemia Reperfusion Injury
    (Cell Press, 2023) Koksal, Zeynep; Kurtipek, Omer; Arslan, Mustafa; Dursun, Ali Dogan; Yigman, Zeynep; Ozer, Abdullah
    Aim: The aim of our study is to show whether the administration of hydrogen-rich saline solution (HRSS) intraperitoneally before left main coronary artery (LAD) ischemia protects the myocardium against ischemia-reperfusion (IR) injury.Materials and methods: After ethics committee approval, 24 Wistar Albino rats were divided into 4 groups, 6 rats in each group. For experimental IR, myocardial ischemia was performed by LAD ligation. Left thoracotomy was performed without ischemia in the Control group (Group C). Left thoracotomy was performed without myocardial ischemia to the rats in the HRSS group, and HRSS was given intraperitoneally (ip) at a rate of 10 ml/kg throughout the procedure. In the MIRHRSS group, a single dose of 10 ml/kg HRSS was administered 5 min before reperfusion. Histopathological and biochemical parameters were compared in myocardial tissue samples taken at the end of the reperfusion period.Results: When the groups were compared among themselves in terms of TOS and TAS levels, there was a significant difference between the groups (p = 0.006, p = 0.002). The severity of cardiomyocyte degeneration was significantly greater in MIR group than that in the control and HRSS groups (p = 0.002 and p = 0.001, respectively), as well as severity score of cardiomyocyte degeneration was higher in MIR-HRSS group compared with HRSS group (p = 0.035).Conclusion: Our study shows that HRSS is protective in IR injury, with the application of HRSS 5 min before reperfusion, interstitial edema severity, subendocardial haemorrhage are reduced, and oxidant status parameters are increased, while antioxidant status parameters are decreased. We believe that when it is supported by other studies, the protective effects of HRSS on IR damage will be shown in detail and its indications will be expanded.

    Therapeutic Efficacy of Boric Acid Treatment on Brain Tissue and Cognitive Functions in Rats With Experimental Alzheimer's Disease
    (Dove Medical Press Ltd, 2023) Ozdemir, Cagri; Arslan, Mustafa; Kucuk, Aysegul; Yigman, Zeynep; Dursun, Ali Dogan
    Introduction: Oxidative stress has an important role in the pathophysiology of Alzheimer's disease (AD), the most common type of dementia. Boric acid (BA) contributes significantly to the protection of the brain by reducing lipid peroxidation and supporting antioxidant defense. We aimed to evaluate the therapeutic potential of BA treatment in AD rats. Materials and Methods: Four groups were formed as Control (C), Alzheimer's (A), Alzheimer's + Boric acid (ABA), Boric acid (BA). Intracerebroventricular injection of Streptozotocin (STZ) was preferred to create an AD. After 4 weeks, BA was applied 3 times every other day. The Radial Arm Maze Test (RAMT) was used to evaluate memory and learning abilities. Biochemical and histopathological evaluations were made in the hippocampus. Results: Initial RAMT inlet/outlet (I/O) numbers were similar. Two weeks after STZ injection, I/O numbers decreased in group A and ABA compared to group C and BA (p<0.05). After the second BA application, I/O numbers increased in the ABA group compared to the A group (p<0.05). In group A, PON-1, TOS and OSI levels were higher and TAS levels were lower than in groups BA and C. After BA treatment, PON-1 and OSI levels were lower in the ABA group than in the A group (p<0.05). Although there was an increase in TAS value and a decrease in TOS, this did not make a statistical difference. The thickness of the pyramidal cell in CA1 and the granular cell layers in the dentate gyrus, and the number of intact and degenerated neurons in the pyramidal cell layer were similar between the groups. Discussion: Significant improvement in learning and memory abilities after BA application is promising for AD. Conclusion: These results show that BA application positively affects learning and memory abilities, and reduces oxidative stress. More extensive studies are required to evaluate histopathological efficacy.

    Evaluation of the Efficacy of Silymarin and Dexmedetomidine on Kidney and Lung Tissue in the Treatment of Sepsis in Rats With Cecal Perforation
    (Spandidos Publ Ltd, 2024) Yavuz, Aydin; Kucuk, Aysegul; Ergorun, Aydan Iremnur; Dursun, Ali Dogan; Yigman, Zeynep; Alkan, Metin; Arslan, Mustafa
    Sepsis is a systemic inflammatory response syndrome that develops in the host against microorganisms. This response develops away from the primary infection site and results in end-organ damage. The present study aimed to investigate the protective and therapeutic effects on lung and kidney tissue of silymarin (S) and dexmedetomidine (DEX) applied 1 h before and after sepsis induced by the cecal ligation and puncture (CLP) method in rats. A total of 62 rats was randomly divided into eight groups: i) Control (n=6); ii) cecal perforation (CLP; n=8); iii) S + CLP (n=8; S + CLP; S administered 1 h before CPL); iv) CLP + S (n=8; S administered 1 h after CLP); v) DEX + CLP (n=8; D + CLP; DEX administered 1 h before CLP); vi) CLP + D (n=8; DEX administered 1 h after CLP); vii) SD + CLP (n=8; S and DEX administered 1 h before CLP) and viii) CLP + SD (n=8; S and DEX administered 1 h after CLP). After the cecum filled with stool, it was tied with 3/0 silk under the ileocecal valve and the anterior surface of the cecum was punctured twice with an 18-gauge needle. A total of 100 mg/kg silymarin and 100 mu g/kg DEX were administered intraperitoneally to the treatment groups. Lung and kidney tissue samples were collected to evaluate biochemical and histopathological parameters. In the histopathological examination, all parameters indicating kidney injury; interstitial edema, peritubular capillary dilatation, vacuolization, ablation of tubular epithelium from the basement membrane, loss of brush border in the proximal tubule epithelium, cell swelling and nuclear defragmentation; were increased in the CLP compared with the control group. Silymarin administration increased kidney damage, including ablation of tubular epithelium from the basement membrane, compared with that in the CLP group. DEX significantly reduced kidney damage compared with the CLP and silymarin groups. The co-administration of DEX + silymarin decreased kidney damage, although it was not as effective as DEX-alone. To conclude, intraperitoneal DEX ameliorated injury in CLP rats. DEX + silymarin partially ameliorated injury but silymarin administration increased damage. As a result, silymarin has a negative effects with this dosage and DEX has a protective effect. In the present study, it was determined that using the two drugs together had a greater therapeutic effect than silymarin and no differences in the effects were not observed any when the application times of the agents were changed.
