 Background & Objective: Bell ’ s palsy (BP) is a relatively common disease characterized^�by the sudden onset of facial paralysis. In this disease, the facial muscle is paralyzed and the patient cannot close the eye or control the saliva in the involved side._�The incidence rate of this disease in the world is between 11.5-40.2 cases per 100,000. The cause of this disease is yet to be found. This study is an attempt to investigate the demographic. Characteristics of these patients as well as the environmental factors involved in this disease in Ardabil.

 Methods: In this cross-sectional study which was cauducted in Ardabil province during a 2-year period (2001-2003) all the patients referring to neurology clinics were evaluated by a questionuaire in terms of demographic features and whether they were affected by the disease.

 Results: 140 cases (out of 6550) were affected by Bell ’ s palsy. The incidence rate was high among 20-30 year-olds (17.85%) and was equal among females and males. Incidence of BP was higher in cold seasons. A high incidence was also observed among farmers, who sweat abundantly due to their job nature.

 Conclusions: The results are consistent with hypotheses regarding viral etiologies [e.g., reactivation of herpes simplex] of Bell ’ s palsy and it can be activated by cold exposure. The results also indicated that the disease is more prevalent in cold seasons.

  Background & Objective: Yersinia spp is from Enterobacteriacea family. The members of this group are all gram negative bacilli or cocobacili and non-spore and negative heme-oxidase which casuses a vast spectrum of diseases in humans the commonest one of which is gastroenteritis. Other diseases and clinical syndromes are septicemia, mesenteric lymphadenitis, Appendicitis, pharyngitis and rarely Reiter's syndrome. Due to frequent reports of febrile gastro-enteritis from Health centers of Ardebil, the probability of gastroenteritis resulted from Yersinia in this cold province is predictable. Thus this study was done to determine the role of Yersinia spp in the diarrhea of children under 5 in the cold seasons of the year in Ardebil.

  Methods: Stool samples from 490 children under 5 with diarrhea in a 7-month period were collected, and transferred in carry-Blair to the laboratory. Stool samples were cultured on Mac-Conkey agar and Salmonella-Shigella agar and Yersinia selective agar, TCBS agar and selenate agar. After adequate incubation, the growing colonies were identified according to the standard biochemical methods.

  Results: of 490 samples, only 405 were suitable to be cultured of which 9.38% pathogenic bacteria were isolated. The frequency distribution of the separated bacteria were as follows Y.enterocolitica, 13 species vibrio, 11 species Enteropathogenic E.coli, 6 species Salmonella, 5 species Shigella, 2 species and plesiomonas, one species.

  Conclusion: The findings of this study are the indicator of the role of Yersinia spp in diarrhea in the cold seasons of the year in the cold and mountainous province of Ardebil. On the other hand, the frequency of isolated vibria was due to simultaneous cholera epidemy in this area.

  Background and objectives: Common cold is the most common disease in children. Young children have an average of 6 to 7 colds each year. Some complications of common cold include: secondary bacterial infections, school absence and excessive cost for treatment. The management of the common cold consists primarily of symptomatic treatment. An effective and safe drug is needed to reduce the duration of common cold ۥ s symptoms in children and reduce subsequent complications. In some studies zinc sulfate has showed an antiviral effect and immune enhancing activity. Therefore this study designed to evaluate the efficacy of zinc sulfate in duration of cold ۥ s symptoms in children.

  Methods: This was a clinical trial study. The subjects were children between 1 - 7 years old with common cold that attended to pediatrics clinic of Arak Amir Kabir Hospital. The study included 112 patients randomized in two groups. One group received zinc sulfate within 10 days and other group didn’t receive this drug. Using a researcher made questionnaire duration of symptoms: rhinorhea and nasal obstruction, cough, sneezing, fever and duration of illness, in both groups were evaluated.

  Results: Consumption of zinc sulfate significantly reduced the mean duration of rhinorhea and nasal obstruction in children with common cold (p < 0.05). Also the mean duration of cough in zinc group was lower than the control group (p < 0.05). Compared to the group that didn’t receive zinc sulfate, the zinc group had shorter mean duration of sneezing (p < 0.05). Also the mean duration of fever in zinc group was shorter than the other group (p < 0.05). The mean duration of illness in patients who had received the zinc sulfate was significantly less than the other group (p <0.05). No side effect was observed in subjects received zinc sulfate.

  Conclusion: According to the results zinc sulfate can be administered with other supportive treatments of common cold, for reduction of symptoms duration and complications in children.

Background & objectives: Minimizing muscle damage and inflammation can boost the immune system and improve sport performance. The aim of this study was to investigate the effect of 8 weeks of resistance training-cold water immersion and curcumin supplementation on muscle injury and inflammation following a session of acute strength activity in futsal players men.
Methods: twenty futsalist volunteered to participate in the study and were randomly assigned to experimental and control groups. Blood sampling was performed after 12 hours of night fasting during four stages. After the first phase of blood sampling, both groups were performed one session of acute circular strength training, then, the second phase blood sampling was performed. 48 hours later, the experimental group performed 8 weeks of circular resistance training, three sessions per week as in the acute strength training and were immersed immediately after exercise, 20minutes at 5-10°C in cold water and used 150mg curcumin supplementation. forty eight hours after the last training session and last using curcumin, blood sampling was performed in both groups. Then, both experimental and control groups performed the second acute circular strength training and the fourth stage blood sampling was performed. The differences of variables at different time intervals were compared with 2×4 two-way ANOVA and differences between the two groups were investigated  with Independent-Samples T-Test at significance level of p<0.05.
Results: Creatine kinase and white blood cells significantly increased in both groups after the first acute strength activity (p=0.049). Performing 8 weeks of resistance training-cold water immersion and curcumin supplementation, significantly decreased creatine kinase and white blood cell counts (p=0.024). Also, 8 weeks of resistance training-cold water immersion and curcumin supplementation, significantly reduced creatine kinase and white blood cells following acute second strength activity (p=0.021).
Conclusion: Appears to, 8-week resistance training-cold water immersion and curcumin supplementation following a session of acute strength training reduce muscle injury and inflammation in futsal players  men.
