Background & aim: Given the existence of 10 different genotypes of the parasite Echinococcus granulosus from different hosts and intermediate and final impact of these genotypes in the life cycle of the parasite and its transmission to humans, the purpose of this study was to determine the molecular characterization of isolates of hydatid cysts in industrial slaughterhouses of Yasuj city. Methods: In this study, 93 animal isolates (56 goat, 31 sheep and 6 cattle) were collected from the industrial slaughterhouse of Yasuj city. The genomic DNA corresponding to protoscolices was extracted, using the standard Phenol–Chloroform method. The fragment of DNA-ITSI of each sample was assessed by PCR with designed primers of EgF, EgR and then amplified. Moreover, the PCR products were assessed by electrophoresis and digested by the Alu I and Rsa I enzymes. RFLP products were evaluated by electrophoresis. Results: Using a PCR test, rDNA-ITSI of all isolates of similar size bands and 1000 bp were obtained respectively.The patterns generated by RFLP using Alu I and Rsa I enzymes, showed Echinococcus granulosus G1 genotype in all isolates. Conclusion: This study showed that strain G1 is the predominant strain causing hydatid cysts in different organs of the animal in Yasuj.

Background and Aim: Multiple sclerosis is one of the most common chronic diseases of the central nervous system. In recent years there have been a growing number of diseases. The purpose of this study was to evaluate the effectiveness of cognitive and behavioral group therapy on coping styles and self-control in patients with multiple sclerosis in Urmia
 
Methods: This was a quasi-experimental design with pretest-posttest design with control group. The statistical population of this study was all patients with MS. In Urmia, in the year  of 1395. There were 30 patients in the experimental group and one in control group (15 in each group).  Using randomized simple sampling and drafted random sampling They were selected by referring to the MS Society. Before the implementation of the educational programs, the two groups were tested by the Andler & Parker Coping Style Questionnaire and Tangie's self-control styles, then they were trained for the experimental group of cognitive-behavioral therapy and the control group did not receive any training. After conducting educational programs, both groups were tested by questionnaires. Covariance analysis was used to analyze the data
 
Results: The results of this study showed that cognitive-therapist treatment has an effect on coping styles and self-control in MS patients. In the other words, cognitive-behavioral therapy increased the problem-oriented coping style (p <0.004) and decreased emotional-focused coping style (p <0.004), avoidant coping style (p <0.005) ) and self-control (p <0.002) in patients.
 
Conclusion: The results emphasize the importance of these interventions in MS patients and the presentation of new horizons in interventions.
