Abstract
Taoxoplasma gondii is an important food-borne parasite transmitted primarily from animals to humans through meat consumption, mainly pork and lamb, as well as through oocysts shed by cats. Infection in humans can cause severe fetal malformations, ocular complications or encephalitis. Toxoplasmosis infection during pregnancy, especially in sheep, often results in abortion, representing considerable economic loss.The aim of this study was to investigate whether Toxoplasma gondii surface antigens can protect experimental mice against T. gondii infection. Materials and Methods: To immunize experiments, we evaluated a virulent strain (RH) for challenge experiments.Surface antigens recovered from tachyzoites in RPMI-1640 culture with MEGA-10. Groups of 17 male mice were intraperitoneally (i.p.) & intrapdermal(i.d) immunized with 2 doses at 10 day intervals. Blood samples were collected from tail veins 21 days after last immunization. Antibody was detected using IFAT. 21 days after the last immunization, both groups were challenged (i.p.) with 2 × 103 RH strain tachyzoites. Results: The results showed an increase of antibody levels after each immunization.Finding showed that immunized mice had longer survival than mice from the control group. Conclusion: Adjuvants play an important role in the efficacy of immunizations.However,suggested that with use of other adjuvants(ISCOM)and surface proteins(P30) for better stimulating the humoral and cellular immune responses.

Abstract
Psychotherapy for bipolor disorder has been very much neglected. The aim of this study was to determine and compare the meta cognitive, emotional processing training (MEPT) with medical and standard therapy (drug) in increasing emotional, cognitive and social skills, of the patients with bipolar disorders. Materials and Methods: This semi experimental study with control group was carried out on 32 females in the 16-40 age bracket, diagnosed with bipolar disorder by means of DSM - IV –R criteria selected among referrals from Isfahan hospitals and psychology clinics. One group randomly received medical therapy plus MEPT. The second group (control group) received standard drug therapy. Data gathering instruments were a semi – structural interview based on DSM – IV – R criteria and the following questionnaires: Mania (Bech, et al, 1979), Depression (Hamilton, 1980), Emotional intelligence (Cooper, 1999), Self – control (Rosenbaum, 1980), Insigt (David, et al, 1992), Social function (Hurry, et al, 1983). And the Aconomic, social, cultural questionnaire was used to control social ststus of the subjects. this questionnaire was made by the researcher. Results: The MEPT method influenced on increasing all of the emotional skills, sub scales and total scales. And also influenced on cognitive scales such as: dysfunctional thought, (p=0. 000), insight (p=0. 05), self – control (p=0. 000). Social skills could be increased (p=0. 02) by use of MEPT. Conclusion: Using pschological treatment in addition to pharmacotherapy increases treatment efficay. Therefor an educational program about MEPT is necessary for therapists.

Abstract
Background : Metacognitive beliefs interact with emotional disorders and this matter can be used in educational programs and psychological interventions. The purpose of this study was to investigate the relationship between metacognitive beliefs and anxiety and depression.
Materials and Methods: In this correlation study, at first, 140 persons were chosen with cluster sampling method. They completed 3 questionnaires including Cartwright-Hatton and Wells metacognition questionnaire, Cattell Anxiety questionnaire and Beck depression questionnaire. Then we used multiple regression, in order to analyze 117 persons' data ( 84 males, 33 females), who had average age 31.6 with standard deviation 6.8.
Results: The results indicated that there is a positive relationship between metacognitive beliefs anxiety and depression. Metacognitive beliefs, correlation coefficient with anxiety was 0.59 and 0.67 with depression. Two metacognitive belief's components, cognitive competence and uncontrollability, can predict 40% of anxiety variance and 50% of depression variance. Moreover, belief's component about uncontrollability and belief about cognitive competence have positive relations with trait anxiety and belief's component about uncontrollability has positive relation with state anxiety.
Conclusion: The results of this study, like other previous researches, show that paying attention to metacognitive beliefs in educational programs and psychological interventions can be effective in prevention, decrease and treatment of emotional disorders.

Abstract
Background: Happiness is a concept that has become important in recent years, due to its important role in mental health. Therefore, the present study was conducted to determine the relationship between personality characteristics, emotional intelligence, attachment style and voluntary activities with the level of happiness among employed women.
Materials and Methods: The research method is descriptive-correlational. The statistical population consisted of 12373 women employed in Lorestan's departments and organizations, from which 400 people were selected, based on the Cochran's formula by Multi-stage cluster sampling. Data was collected through Neo Characteristic Scale, Shering Emotional Intelligence, Collins & Read Attachment Inventory, Voluntary Activities Questionnaire and Oxford Happiness Questionnaire, and was analyzed using Pearson correlation and stepwise regression analysis.
Results: The results showed that there is a significant relationship between personality characteristics, emotional intelligence and voluntary activities with happiness (P<0.001), and among the components of attachment style, only the component of anxiety has a negative and significant correlation with happiness (r=-0.20). The results of regression analysis indicated that self-motivation variables (from emotional intelligence components), extroversion and voluntary activities with positive beta coefficient and neuroticism with negative beta coefficient can predict happiness (P<0.001).
Conclusion: Based on the results, it is suggested that managers of employment organizations hold field workshops focusing on the education of emotional intelligence, sporting activities, recreation, and holding happy communities (concerts, comedy programs, etc.) in order to promote happiness and that they pay attention to the central role of attachment and personality traits in happiness.

Abstract
Background: The incidence of heart disease increase with age. Green tea is an antioxidant which can prevent cellular aging. Therefore, the present study aims to investigate the effect of 12 weeks of green tea extract consumption on total antioxidant capacity (TAC), malondialdehyde (MDA) levels and superoxide dismutase, glutathione peroxidase and catalase activity of old rats' heart tissue in response to acute exhaustive exercise.
Materials and Methods: 32 male rats were randomly categorized into two groups of supplement and non-supplement each consisting of 16 rats. The supplement group received green tea extract for 12 weeks. At the end of the 12 weeks, each of these groups was further divided into two groups of rest and acute exhaustive exercise. The non-supplement with the rest group was called control group. The non-supplement with exercise group was called exercise group. Further, the supplement group with the rest was called supplement group and finally the last group was entitled supplement with exercise. After 12 weeks of taking green tea extract, one session of acute exhaustive exercise was held on the treadmill. Sandwich ELISA method was used to measure TAC and MDA content and superoxide dismutase, glutathione peroxidase and catalase activity
Results: The results showed that 12 weeks of green tea extract consumption increased TAC and decreased MDA levels. Furthermore, increased superoxide dismutase, glutathione peroxidase and catalase activity in response to a bout acute exhaustive exercise.
Conclusion: According to the results of this study, 12 weeks of green tea extract consumption can increase TAC levels and increase the activity of antioxidant enzymes at rest and after acute exhaustive exercise.
