    Objectives: This study investigated the effect of krill oil (KO) on liver damage caused by acetaminophen (APAP). Methods: In the present study, the control and APAP groups were given distilled water by gavage for 14 days. In addition, the KO and APAP+KO groups were given 500 mg/kg krill oil by gavage for 14 days. At the end of 14 days, 0.9 % sodium chloride solution (saline solution) administration was applied intraperitoneally to the control and KO groups. Meanwhile, 220 mg/kg acetaminophen was administered to the APAP and APAP+KO groups. While some biochemical parameters in plasma were examined, some oxidative stress parameters in plasma and liver tissue were evaluated. Apoptotic and inflammatory responses of some primer sequences determined by quantitative Real-Time PCR (qPCR) in liver tissue. After histopathological examination of liver tissue, immunohistochemical analysis was performed with Wnt inhibitory factor-1 (Wif-1), beta-catenin (ss-Catenin), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Results: The Wif-1 positivity in hepatocytes increased significantly in the APAP group (5.29 +/- 0.71) compared to the control (1.14 +/- 0.51), and KO (2.14 +/- 0.55) groups (p<0.001). The 8-OHdG positivity in hepatocytes increased significantly in the APAP group (19.57 +/- 0.58) compared to the control (0.43 +/- 0.20), KO (3.57 +/- 0.48), and APAP+KO (4.00 +/- 2.53) groups (p<0.001). Conclusions: As a result, krill oil could be used as a nutritional supplement to protect the liver against acetaminopheninduced liver injury.

    Effect of ondansetron for preventing of ovarian hyperstimulation syndrome: in an experimental rat model
    (Taylor & Francis Ltd, 2022) Bakirci, Suekrue; Sagsoez, Nevin; Devrim, Tuba; Sahin, Yasar; Bulanik, Murat; Goezueyukari, Hilal
    Objective: Ovarian hyperstimulation syndrome is an iatrogenic condition that occurs in the treatment of infertility. There is no specific treatment available for OHSS. Cabergoline is a dopamine receptor 2 agonist and VEGF-VEGF2 receptor antagonist . Recently, cabergoline has been widely used to prevent the development of OHSS and reduce its severity Serotonin is known as a neurotransmitter and thought to have a role in the mechanism of angiogenesis and in signaling in endothelial cells. Serotonin is said to have similar effects to VEGF . Ondansetron is Selective Serotonin (5-HT3) Receptor Antagonist . It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting. In the clinical practice today, there is no choice other than cabergoline, to prevent occurrence and reduce severity of OHSS, and sometimes its effects are limited. Methods: In our study, we compared the effect of cabergoline and ondansetron. 32 immature rats were used and the OHSS model was created. Parameters such as hematocrit value , ovarian size, the number of follicles in the ovary, endometrial capillary congestion and thickness values were evaluated and compared. Results: As a result, in our study, it was seen that ondansetron was effective on OHSS in many parameters. It is thought to be as effective as cabergoline. When we look at the literature, this is the first study in which ondansetron was evaluated for this purpose. It would be good to show this effect of ondansetron with other studies.
