Blood Levels of Oxidant/Antioxidant Parameters in Rats Infected with Toxoplasma gondii

Toxoplasmosis is a common parasitic infection in the world. Since increased free radicals and oxidative stress are reported in many parasitic diseases the purpose of the present study was to evaluate the oxidative stress in acute and chronic toxoplasmosis. RH strains of Toxoplasma tachyzoites were used in the present study. Twenty-five female rats were infected with the parasite while 25 other rats were as the control group that received normal saline. Zero-, 5-, 7-, 10-, and 45-day postinfection (DPI) blood samples were taken. Some parameters related to oxidant and antioxidants such as antioxidant enzymes, malondialdehyde, and total antioxidant capacity were measured. On day 7 after infection, GPX activity and GSH level were significantly increased and in the mentioned day the amount of total antioxidant capacity was significantly reduced. In other cases, there were no significant differences between the groups in different days. Overall, based on the results it seems that, on day 7 after infection, in infected rats responses to oxidative stress were triggered and led to decrease of total antioxidant capacity. Furthermore, glutathione was increased to cope with stress. It seems that probably antioxidant defense system entered the infection to the chronic phase and changed the parasites stage

Epidemiology of mental health problems in female students: A questionnaire survey

Mental health as a state of well-being can be affected by gender. The present work aims to examine the mental health status in female students and recognize its affecting factors. A cross-sectional study on female students of Payame-Noor University in West Azerbaijan, Iran, was conducted among 1632 students. Data collection tools were the demographic data and the General Health Questionnaires (GHQ-28). The results show that 51.5% of the population under study were healthy and 48.5% have had mental disorders. Based on the social effects on the mental health of students, the correlations between age (p = 0.15), location (p = 0.29) and parental education (p = 0.34) with general health status were assessed and there were no significant differences between them. However, birth order (p < 0.002), marital status (p < 0.001) and family income (p < 0.000) had significant differences with regard to mental health status. This study indicates that 43.6% of students are suspected to have mental and physical disorders, and the most effective factor is the socioeconomic condition. The strong correlation between birth order, marital status, and family income and mental health disorders suggests the necessity to pay more attention to all these issues in all at-risk students
