    Purpose: To examine the probable beneficial effects of taxifolin against acrylamide damage in lung tissue. Methods: 18 male albino Wistar rats were divided into healthy (HG), acrylamide (AG) and taxifolin + acrylamide (TAG) groups. Once a day for 30 days, acrylamide was orally administered to the AG group (50 mg/kg), while ACL (50 mg/kg) and TAX (20 mg/kg) were orally administered to TAG group. Protein concentration, malondialdehyde (MDA), and total glutathione (tGSH) levels as well as oxidant and antioxidant molecules concentrations of the rat lung tissues were measured. In addition, degree of mononuclear (MN) cell infiltration and bronchial-associated lymphoid tissue (BALT) hyperplasia was evaluated by the degree of hyperplasia (absent, mild, moderate, severe). The histopathological and biochemical data the groups were compared. Results: When compared in terms of MDA levels, it was found that the AG group had high MDA levels, and the TAG group had low MDA levels. (p < 0.001). TAG group was found to have a higher tGSH level than the AG group (p < 0.001). Compared to the AG group, lower TOS and higher TAS levels were obtained in the TAG group (p < 0.001). In addition, when TOS levels of TAG and HG groups were compared, the TOS levels between the two groups were statistically insignificant (p = 0.213). It has been observed that TAX administration prevents the increase in NF-KB level. When the NF-KB levels of the AG and TAG groups were compared with each other, there was a statistically significant difference (p = 0.001). In the AG group, severe MN cell hyperplasia and BALT hyperplasia were observed histopathologically. It was determined that these findings were alleviated in the TAG group. A histopathologically significant difference was found between AG and TAG groups (p < 0.05). Conclusion: Taxifolin has beneficial effects against lung injury caused by acrylamide, a health damaging environmental factor. Regular use of taxifolin can be recommended, especially in people who are known to have intense contact with acrylamide. There is a need for research studies on this subject.

    The Effect of Adenosine Triphosphate, Benidipine, Sugammadex, and their Combinations upon Cardiac Damage after Temporary Clamping of the Abdominal Aorta in Rats
    (Colegio Farmaceuticos Provincia De Buenos Aires, 2022) Emir, Izzet; Altuner, Durdu; Gulaboglu, Mine; Coban, Taha Abdulkadir; Suleyman, Bahadir; Mammadov, Renad; Ozkaraca, Mustafa
    The aim of our study was to biochemically and histopathologically investigate the protective effect of adenosine triphosphate (ATP), benidipine, sugammadex and (ATP + benidipine + sugammadex) ABS against cardiac damage induced by abdominal clamping and unclamping (ACU) procedure in rats. Rats utilized were divided into six groups as Healthy (HG), Abdominal ACU (AACC), ATP + AACU (ATPG), Benidipine + AACU (BNDG), Sugammadex + AACU (SDXG), ABS + AACU (ABSG). One hour before anesthesia, ATP (25 mg/kg; ip) was administered to the ATPG group, Benidipine (4 mg/kg orally) was administered to the BNDG group, Sugammadex (4 mg/kg ip) was administered to the SDXG and ABS was administered with this specified dose and method to the ABSG group. Distilled water as a solvent was injected to AACC and HG groups. One hour after, laparotomy was performed to the rats, and the abdominal cavity was reached. Ischemia was provided for one hour and then reperfusion for 2 h placing an atraumatic clamp on the suprarenal abdominal aorta of the animals in all groups (except from the HG). The heart tissues extracted from the killed animals were examined biochemically and histopathologically. ATP and benidipine suppressed the increase of oxidant and proinflammatory cytokines better than sugammadex. The ABSG group was found to be almost the same as the healthy group biochemically and histopathologically (p > 0.05). ABS drug form alone was possible to be much more beneficial rather than ATP, benidipine and sugammedex in the treatment of cardiac damage induced by AACU procedure.
