RESUMO

Background Fertility and infertility problems are among the complex issues in medicine. The use of herbal products in the treatment of fertility has been considered as an alternative to synthetic drugs. Celery containing known compounds can have an impact on the fertility rate. The aim of this study was to do a systematic review on conducted studies in conjunction with the celery and reproduction. Methods Required papers were searched from databases like Science direct, PubMed, Scopus, and Springer. Keywords used in this study were "Apium graveolens L.", "fertility", "reproductive system", "sperm", "testis", "delivery", "sexual hormone", "LH", "FSH", "testosterone", "semen", "male", and "female". Out of 238 collected articles (published in the period 1995 to 2015), 222 were excluded due to non-relevance and lack of access to the original article. Results The notable points were the different results seen by different researchers during different treatment periods or at different doses. Of the 16 studies reviewed in this study, 13 studies have mentioned the positive effect of celery on fertility, while three studies reported the inhibitory effects of this plant. Conclusions Celery can have protective effects against substances such as sodium valproate, propylene glycol, and diethyl phthalate causing damages to the testicular structure and spermatogenesis. In this regard, the doses used and the treatment time while using the plant must be accurately investigated. Since there are compounds such as apigenin, the celery can induce inhibitory effects on fertility in case of chronic use or high concentration.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate the salivary testosterone levels under psychological stress and its relationship with rumination and five personality traits in medical students. METHODS: A total of 58 medical students, who wanted to participate in the final exam, were selected by simple random sampling. Two months before the exam, in the basal conditions, the NEO Inventory short form, and the Emotional Control Questionnaire (ECQ) were completed. Saliva samples were taken from students in both the basal conditions and under exam stress. Salivary testosterone was measured by ELISA. Data was analyzed using multivariate analysis of variance with repeated measures, paired samples t-test, Pearson correlation and stepwise regression analysis. RESULTS: Salivary testosterone level of men showed a significant increase under exam stress (p<0.05). However, a non-significant although substantial reduction observed in women. A significant correlation was found between extroversion (r=-0.33) and openness to experience (r=0.30) with salivary testosterone (p<0.05). Extraversion, aggression control and emotional inhibition predicted 28% of variance of salivary testosterone under stress. CONCLUSION: Salivary testosterone reactivity to stress can be determined by sexual differences, personality traits, and emotional control variables which may decrease or increase stress effects on biological responses, especially the salivary testosterone.

RESUMO

Background and Objectives: The measurement of salivary immunoglobulin A is a useful and non-invasive method for measuring stress. Personality traits and rumination act as possible mediators in the relationship between psychological stressors and the immune system. This study was aimed to evaluate the levels of salivary IgA under psychological stress and its relationship with rumination and five personality traits in medical students. Methods: In this cross- sectional study, 45 medical students who intended to participate in the final exam were selected by simple random sampling. Two months before the exam, in the peribasal conditions, the NEO Personality Inventory-Short Form and Emotional Control Questionnaire(ECQ) were completed. Saliva samples were taken from students in both the basal conditions and exam stress conditions. Salivary IgA was measured by an ELISA test. Data was analyzed using paired samples T-test, Pearson correlation analysis, and stepwise regression. Results: A significant reduction of salivary IgA levels was found in exam stress conditions. Also, a significant negative correlation was found between traits of neuroticism and rumination with salivary IgA, as well as a significant positive correlation between of openness to experience and emotional inhibition with salivary IgA. Openness to experience and emotional inhibition may predict a substantial variance (34%) of salivary IgA under exam stress. Conclusions: Salivary IgA is reduced in response to exam stress. In addition, the rumination and personality traits may reduce or increase stress effects on the immune system, particularly the salivary IgA (AU)
