Introduction: Brucellosis is one of the most important zoonotic diseases that causes miscarriage and infertility in animals and causes human fever. The use of the common SS9 strain of Brucella abortus has several side effects for livestock. Brucella P39 protein is one of the plasma peripheral space proteins that is considered as one of the important immunogenic indicators. With the production of the new protein combination of P39, more studies can be done on the ability of this protein to stimulate immune responses against Brucella. Therefore, in this research, the production and purification of this protein in Escherichia coli bacteria has been done as a new compound.
method: In this experimental study, using the polymerase chain reaction, the P39 gene was propagated by the bacterium Brucella abortus. After purifying the P39 gene, it was cloned into plasmid carriers pSK+ and pGEX4T1. Therefore, pSK+-P39 and pGEX4T1-P39 structures were prepared. To produce the recombinant protein P39, the plasmid structure pGEX4T1-P39 first entered the Escherichia coli bacterium BL21. The protein was then produced by IPTG by induction of pGEX4T1-P39 plasmid. The resulting protein was purified using the orderly purification protein glutathione S-transferase. The amount of purified protein was measured using the Brad Ford method.
Results: The nucleotide sequence of the gene propagated by the cloned PCR in the plasmid carrier  pSK+ was exactly the same as the P39 gene of Brucella abortus. Production of P39 protein was performed by induction of pGEX4T1-P39 plasmid. The purified protein content was 200 micrograms per milliliter.
Conclusion: The production of the new protein P39 compound Brucella Abortus, which is unstable in the cytoplasm of the Escherichia coli bacterium, is possible using carriers with additive proteins such as pGEX4T1 in the host of Escherichia coli strain BL21.

Background: Brucella is a gram-negative intracellular bacterium. Since Brucella brings about health and socio-economic problems, its control is of primary importance. The common method of vaccination includes using live attenuated strains of this bacterium. This study was done to evaluate the immunogenicity of Brucella aburtus P39 gene in Balb/c mice. Materials and Methods: In this experimental study, P39 gene was amplified by polymerase chain reaction (PCR) method and after extraction, it was sub-cloned to eukaryotic expression vector pcDNA3. The intramuscular injection of the obtained plasmid to the Balb/c mice was done in three stages. After the last vaccination, immunologic tests, such as proliferative response in lymphocytes, IFN- assessment, IL-5, and determination of IgG2a and IgG1, were run. Results: The level of activation in splenic lymphocytes response was 3.6 and the measured IFN- was 3 ng/ml, whereas IL-5 was insignificant. IgG2a and IgG1 titers were 1.640 and 1.40, respectively. Conclusion: The findings of the immunological analysis show the appropriate immune response in Balb/c mice model after the injection of P39 gene containing plasmid. The immune system response was in Th1 form which decreased the number of bacteria in spleen. Therefore, P39 gene is of appropriate immunogenicity and DNA vaccination is efficient in the activation of cell immune response against this bacterium.

Background: Multiple sclerosis, an immune-mediated demyelinating disorder, is one of the most common diseases of the central nervous system. Two-thirds of patients with multiple sclerosis are women in their child bearing age, 20s and 30s. Multiple sclerosis is followed by neurological disability in young people. The purpose of this study was to determine pregnancy outcomes in patients with multiple sclerosis and compare them with healthy pregnant women. Materials and Methods: In this cohort study,37 pregnant women with multiple sclerosis and 73 healthy pregnant women were compared in terms of pregnancy, child birth, and infant variables. Patient information was collected through questionnaires and evaluated using independent t-test, Chi-square, and Mann-Whitney test. Results: The results showed that pregnancy complications like preeclampsia and gestational symptoms in women with multiple sclerosis were higher than the control group (p=0.001). Instrumental delivery was more in women with multiple sclerosis (p=0.05) and there was not a significant difference between the two groups in terms of neonatal outcomes. Conclusion: The resultsof this study show that some of the complications of pregnancy are higher in women with multiple sclerosis. Also, normal delivery and instrumental vaginal delivery were more in women with multiple sclerosis that couldbe due to fatigue in this population. Hence, these findings should be taken into consideration in planning andmanaging pregnant patients.

Background: Seizure is an abnormal electrical activity probably due to an imbalance between excitation and inhibition in the brain. Pentylenetetrazol (PTZ) is a chemical convulsive agent abundantly used in laboratory animals. PTZ induces a change in glutamate and GABA in the brain which this study investigates the persistence of this change.

Materials and Methods: In this experimental study, 18 male Wistar rats divided into 3 groups. Three i.v doses of PTZ 20, 25 and 30 mg/ml were used to determine the effective PTZ dose. Convulsive behaviors were monitored as tonic clonic and myoclonic twitches. Hippocampal glutamate and GABA contents were measured using a biochemical method.

Results: Dose of 20 was resulted in long latency to and short lasting TC convulsions with a high volume of injected PTZ solution. On the other hand, dose of 25 and 30 led to short latency and long lasting convulsions with low volume of injecting solution. However there was high rate of mortality (100%) in dose of 30 mg/ml. Hippocampal glutamate content was decreased in zero and 20 min groups while GABA content was decreased only in 20 min group.

Conclusion: It is concluded that dose of 25 is the appropriate i.v dose to induce TC convulsions in rats which decreases glutamate and GABA while increases the ratio of glutamate to GABA. Therefore, alteration of glutamate and GABA may be the basis for subsequent seizure induced changes.

Background: Corticosteroids as dexamethasone are used for treating non-specific inflammatory diseases, however, may result in delayed wound healing due to its catabolic effects in skin. Thus, the purpose of the present study was to investigate the effect of quercetin on delayed wound healing in dexamethasone-treated rats.

Materials and Methods: In this experimental study, 40 male Wistar rats were used. After dermal incisions within a distance of 1.5 mm to the spinal column (30 mm length), rats were treated with 0.17 mg/kg dexamethasone, 50 mg/kg quercetin or both until 21 days. Wound healing was evaluated by measuring surface area, percentage of healing, wound length, duration of healing, and wound tensile strength.

Results: Our results showed that the duration of wound healing was significantly increased in dexamethasone treated rats in comparison with control group. In contrast, the rate of healing and skin tensile strength in dexamethasone treated rats receiving quercetin was significantly greater than dexamethasone treated group. In addition, the duration of wound healing in the dexamethasone treated group receiving quercetin was less than dexamethasone group.

Conclusion: This study provides some evidence to support the use of quercetin to accelerating wound healing in dexamethasone treated animals. However, Further research is needed to determine the quercetin mechanisms in acceleration of wound healing.

Background & Aim: This study aimed at comparing efficacy of cognitive behavioral therapy, Zolpidem 10 mg, and waiting list group on illness perception and sleep efficiency in individuals with chronic insomnia disorder. 
Materials & Methods: Participants included 74 (female = 43) individuals with chronic insomnia disorder who were recruited from 2018 December to 2020 February by purposive sampling (inclusive & exclusive criteria). Then, patients randomly allocated to one of the three conditions, including cognitive behavioral therapy (N=25), pharmacotherapy (Zolpidem 10 mg.; N=29), and the waiting list (N=20). All patients were assessed three times at pretreatment, post-treatment, and 3-month follow-up by the Persian version of Brief Illness Perception Questionnaire and Sleep Efficiency Index. The data were analyzed by mixed analysis of variance with Bonferroni post-hoc test and repeated measure analysis of variance. 
Ethical Considerations: All stages of the research have been carried after taking supervising and approving of Kharazmi University's ethics in research committee. 
Findings: The patients who received cognitive behavioral therapy compared to patients in waiting list group, obtained significantly lower scores in illness perception and sleep efficiency during post-treatment and 3-month follow-up. Efficacy of pharmacotherapy only observed during post-treatment but there were no significant differences between pharmacotherapy and waiting list patients during 3-month follow-up.
Conclusion: Cognitive behavioral therapy for insomnia reduced significantly illness perceptions and sleep efficiency during 3 months. All the treatment gains remain stable even 3 months later treatment ends. In addition, not receiving any treatment in waiting list and gradually discontinued the treatment in pharmacotherapy group leads to decreasing of sleep efficiency and increasing of illness perception.
