Abstract
Introduction: Different strains of Echinococcus Granulosus have been found in endemic areas of Iran. This variation has a significant aspect in the field of medical parasitology and veterinary and also in epidemiology, pathology, control and prevention of Hydatid cyst infection. Morphology, epidemiology and biochemical studies can be carried out to determine Hydatid cyst strains in human and animal origins as host. This study was done to measure different biochemical compositions of liver Hydatid cyst fluids in human, sheep, goat, cattle and camel in 2004.
Materials and Methods: In a cross sectional-analytical study, 112 samples of Hydatid fluids were collected from the liver cysts of different hosts: 16 sheeps, 64 cattles, 12 goats and 10 camels in slaughter houses of Sari and Ghaemshahr and 10 human in Imam hospital. All cyst fluids were centrifuged at 4500 rpm at 4˚C for 45 minutes and the supernatants were analyzed for various biochemical parameters.
Results: Quantitative differences were observed in the levels of Sodium, Glucose, Urea, Alanin Aminotransferase (AST) in liver cystic fluids obtained from different hosts, although these differences were not statistically insignificant. However, differences in the levels of Potassium, Calcium, Triglycerides, Cholesterol, Uric acid, Creatinin, Albumin, Gamma Glutamyl Transferase, Aspartat Aminotransferase (AST) and Creatinine Phosphokinase (CPK) in different Hydatid cyst fluids were statistically significant (P<0.05).
Conclusion: Differences in biochemical composition of different Hydatid cyst fluids suggest the possible existence of more than one strain of Echinococcus Granulosus in human and other intermediate domestic animal hosts in Mazandaran.

Abstract
Background: Oxidative stress plays an important role in the pathogenesis of hypertension- induced cardiac hypertrophy. Plants are a rich source of antioxidant compounds. Thymol is a natural monoterpen phenol which is plentiful in some plants and shows many biological effects. The aim of the present study was to assess the effects of thymol on activity of antioxidant enzyme catalase, malondialdehyde (MDA) level and the activity of the inhibition of free radical DPPH (2,2-Diphenyl-1-picryl-hydrazyl), following left ventricular hypertrophy in rats.
Materials and Methods: In this experimental study, rats were divided into hypertrophied group without any treatment (H group) and rats pretreated with 25 and 50 mg/kg/day of thymol (Thy25+H and Thy50+H groups, respectively). Intact animals were served as control (Ctl). Animal model of left ventricular hypertrophy was induced by abdominal aortic banding. Serum catalase (CAT) activity, malondialdehyde (MDA) level and the activity of inhibition of free radicals DPPH were determined by the biochemical methods.
Results: In Thy25+H and Thy50+H groups, the CAT activity was increased significantly in serum (p<0.01, vs. Ctl). Also, serum level of MDA was decreased significantly compared to the group H in Thy25+H and Thy50+H groups (p<0.05 and p<0.001, respectively). The effect of inhibiting DPPH free radicals was increased significantly in Thy25+H and Thy50+H groups compared to the group H (p<0.001 and p<0.05, respectively).
Conclusion: The findings of this study suggest that thymol as an antioxidant causes cardioprotective effects and as well as prevents left ventricular hypertrophy via augmentation of serum antioxidant capacity.

Abstract
Introduction: For many people, infertility is a prominent crisis and cause of mental stress that causes many unfavorable psychological reactions. The purpose of the research is to design a cognitive-behavioral coping training package with the stress of infertility and its effectiveness on the hope of infertile women.
Methods: The present study was conducted using a mixed method using the qualitative part, content analysis type, and the quantitative part, semi-experimental, in the pre-test-post-test-two-month follow-up design with the control group. The statistical population of this research was infertile women referring to infertility centers and gynecology and infertility specialists in Kermanshah in 2022. A sample of forty women was selected as a sample using the purposeful sampling method and replaced in two groups (experimental and control) in a simple random manner. Data were collected from Newton et al.'s infertility stress questionnaire (1999) and Schneider's Hope (1991). The data was analyzed using a content validity test and repeated measurement variance analysis tests.
Results: The designed educational package was valid and adequate. The findings showed a significant difference between pre-test, post-test, and follow-up in the component of hope, and this difference continued until the follow-up stage.
Conclusions: The educational package on cognitive-behavioral coping with the stress of infertility of infertile women can be used to reduce the stress and increase the hope of infertile women.
