Investigation of hepatoprotective effect of some algae species on carbon tetrachloride-induced liver injury in rats

The aim of this study was to investigate hepatoprotective effect of some algae species such as Spirulina platensis, Chlorella vulgaris, Laminaria japonica, Sargassum sp. on experimental acute hepatotoxicity model that induced with carbon tetrachloride (CCl4) in rats. Algaes at a dose of 200 mg/kg and Silymarin at a dose of 25 mg/kg were orally administered for 7 days followed by CCl4 at a single dose (0.5 ml/kg), at the 8th day to cause experimental acute hepatotoxicity. Levels of biochemical (AST, ALT etc.), lipid peroxidation (MDA), antioxidant (GSH, CAT, GPx) parameters and histopathological examination were carried out to investigate the hepatoprotective effects of algae. In Sp group ALT and ALP levels were significantly decreased compared with CCl4 (p <.05). Histological liver structures of Sp group were similar to the control group. MDA, GPx and CAT levels of Sp and La groups were significantly different compared with CCl4 (p <.05). Based on these results, algae species able to minimise the toxic effects of CCl4 and especially S. platensis could be used in the purpose of protection against chemical-induced hepatotoxicity. © 2019 Informa UK Limited, trading as Taylor & Francis Group.Mustafa Kemal ÜniversitesiThis work was financially supported by Scientific Research Projects Coordination of Mustafa Kemal University (Project no:14660)

A Multicenter Study: How Do Medical Students Perceive Clinical Learning Climate?

Background The relationship between students and instructors is of crucial importance for the development of a positive learning climate. Learning climate is a multifaceted concept, and its measurement is a complicated process. The aim of this cross-sectional study was to determine medical students’ perceptions about the clinical learning climate and to investigate differences in their perceptions in terms of various variables. Methods Medical students studying at six medical schools in Turkey were recruited for the study. All students who completed clinical rotations, which lasted for 3 or more weeks, were included in the study (n=3,097). Data were collected using the Clinical Learning Climate Scale (CLCS). The CLCS (36 items) includes three subscales: clinical environment, emotion, and motivation. Each item is scored using a 5-point Likert scale (1: strongly disagree to 5: strongly agree). Results The response rate for the trainees was 69.67% (n=1,519), and for the interns it was 51.47% (n=917). The mean total CLCS score was 117.20±17.19. The rotation during which the clinical learning climate was perceived most favorably was the Physical Therapy and Rehabilitation rotation (mean score: 137.77). The most negatively perceived rotation was the General Internal Medicine rotation (mean score: 104.31). There were significant differences between mean total scores in terms of trainee/intern characteristics, internal medicine/surgical medicine rotations, and perception of success. Conclusion The results of this study drew attention to certain aspects of the clinical learning climate in medical schools. Clinical teacher/instructor/supervisor, clinical training programs, students’ interactions in clinical settings, self-realization, mood, students’ intrinsic motivation, and institutional commitment are important components of the clinical learning climate. For this reason, the aforementioned components should be taken into consideration in studies aiming to improve clinical learning climate.PubMedWoSScopu
