Effects of the Ethanol Extracts of Ficus deltoidea leaves on the Reproductive Parameters in Male Mice

BACKGROUND: Indonesia, and in particular East Kalimantan, has a very high diversity of flora that has the potential to be used as traditional medicine. One type of flora is the leaves of Ficus deltoidea Jack. At present, there are no available data about the impact of F. deltoidea leaf ethanol extract on the male reproductive system. AIM: The present study aims to investigate the effect of F. deltoidea leaf ethanol extract on several parameters of reproductive function in male mice, including changes in testicular biochemistry, reproductive hormones profile, and histopathology of the testes after subchronic exposure. METHODS: In total, 25 male mice were divided into five groups: The control group and four treatment groups that received extract doses of 125, 250, 500, and 1000 mg/kgbw for 28 days, respectively. At the end of the treatment, surgery was performed, weight of body and reproductive organs (testis, epididymis, and seminal vesicles) were measured, and testicular biochemistry, reproductive hormone profile, antioxidant activity, and testes histopathology were analyzed. RESULTS: In the subchronic toxicity test, there were no significant changes in body weight or in weight and relative weight of reproductive organs. Levels of testosterone, luteinizing hormone and follicle-stimulating hormone, protein, cholesterol, and activity of enzymes in the testes (alkaline phosphatase, lactate dehydrogenase, and glutamyltransferase) and activity of the enzyme superoxide dismutase increased significantly in the treated mice when compared to control mice (p < 0.05). Glycogen levels were not significantly different, but lipid peroxide (MDA) decreased significantly, though it did not change the histological structure of the testes. CONCLUSION: Ethanolic extract of the leaves of F. deltoidea Jack does not cause toxic effects and even has a beneficial effect on the reproduction of male mice by increasing fertility, reproductive hormones, and antioxidant activity, and it does not change the histological structure of the testes.

Safety effect of fractions from methanolic leaf extract of Ocimum gratissimum on reproduction in male wistar rats

This study evaluates the reproductive toxicity of ethyl acetate and butanolic fractions from crude methanolic leaf extract of Ocimum gratissimum in male Wistar rats. Acute toxicity was assessed to determine the safety dose, Sub-chronic reproductive toxicity studies were carried out by administering daily 25, 100 and 400 mg/kg body weight doses of the fractions to respective group of animals and 1 ml of normal saline daily for the control group for 28 days. Blood, epididymis and testes were harvested for reproductive hormones, sperm parameters, and histopathologic analysis respectively. There was significant (P < 0.05) increase in serum levels of testosterone, body-weight gain, sperm count. There was also apparent increase in mean-testicular weight and preservation of testicular histology with increase spermatogenesis in both the ethyl acetate and butanolic fraction treated groups compared with control. Serum levels of luteinising hormone was however significantly (P < 0.05) decrease across the groups compared to control. These effects were more pronounced in the butanolic fraction group compared to the ethyl acetate treated group. Sperm motility was also significantly (P < 0.05) higher in the ethyl acetate treated group compared to control. Findings from this studies demonstrate that these fractions were non-toxic at the tested doses with regards to male reproduction but, rather, exhibited fertility enhancing effects which was better with the butanolic fraction. Our findings also shows that the ethyl acetate fraction may be safer than the butanolic fraction.

The relationship between quality of life and posttraumatic stress disorder or major depression for firefighters in Kaohsiung, Taiwan

OBJECTIVE

The work of firefighters involves the risk of exposure to the harmful effects of toxic substances as well as the possibility of enormous emotional shock from disasters, which may result in psychiatric impairments and a lower quality of life. Therefore, we examined quality of life, prevalence of posttraumatic stress disorder (PTSD) and major depression, and the related risk factors for firefighters in Kaohsiung, Taiwan.

METHODS

This is a two-stage survey study. During the first stage, we used the 36-item Short-Form Health Survey (SF-36) and the Disaster-Related Psychological Screening Test (DRPST) to assess quality of life, probable PTSD, probable major depression, and the related risk factors for 410 firefighters. During the second stage, psychiatrists categorized these probable cases according to self-reported questionnaires against DSM-IV into PTSD or major depression group, subclinical group, and health group. All the data were analyzed with SPSS 10.0 Chinese version.

RESULTS

The estimated current prevalence rates for major depression and PTSD were 5.4% (22/410) and 10.5% (43/410), respectively. The firefighters with estimated PTSD or major depression scored significantly lower on quality of life measures than subclinical PTSD/major depression and mentally healthy groups, which was evident in eight concepts and two domains of the SF-36. The major predictors of poor quality of life and PTSD/major depression were mental status, psychosocial stressors, or perceived physical condition.

CONCLUSION

Firefighters have a higher estimated rate of PTSD, and the risk factors that affect quality of life and PTSD/major depression should encourage intervention from mental health professionals.
