Background: Postoperative shivering is a common problem with multiple complications. This study was compared effect of low doses of Ketamine with Pethidine for controlling postoperative shivering. Methods and Materials: This clinical trial was done on 189 elective cesarean section with ASA class I or II who had postoperative shivering. Patients with grade 2 or higher were divided in three groups and were injected 0.3mg/kg Ketamine and 0.5mg/kg Pethidine intravenously. In 5th and 10th minutes after injection, they were investigated for shivering intensity. Results: After 5 minute of injection drugs rate and intensity of shivering in Pethedine group was less than ketamine group. Ketamine with 0.5 mg/kg was more effective than 0.3mg/kg dose of it and Ketamine(p=0.041). In group with 0.5mg/kg dose of Ketamine, rate and intensity of postoperative shivering was more reduce than group with 0.3mg/kg of it in recovery(p=0/007). In Pethedine group rate and intersity of shivering was more reduce then 0.5mg/kg dose of Ketamine(p<0/001). This demonstrated that Pethedine is more effective than Ketamine. Conclusion: Although 0.5mg/kg dose of Ketamine has considerable effect on control of shivering but Pethedine is still a better choice for this side effect.

Background: Recognition of mortality-related factors in Intensive Care Units (ICUs) could increase efficiency and effectiveness of these units. This research determined the relationship between the physical structure, human resources and their relevance to mortality rate in Intensive Care Units. Methods and Materials: In this cross-sectional study, all ICUs of hospitals in Markazi province were considered. Data gathering tools were resource (human, physical and training) questionnaires and checklists which their reliability and validity were accepted by Monitoring and Validation Center of Ministry of Health. Mortality rate after 24 hours of admition was also determined in relation to hospital resources and activities. Data were analyzed with descriptive statistics, Spearman and Kruskal-Wallis tests. Results: Total score of human, physical and training resources in hospitals of Markazi Province is 55 percent of the country standard score. Mortality ratio after 24 hours of admission, to all patients (released and deceased patients) was highest in Vali-e-Asr hospital (25%) and lowest in Saveh Shahid Chamran Hospital (5%). There wasn’t significant difference in this ratio among hospitals. There were no significant difference between obtained scores of each resource (human, physical and training) among University, Social Insurance and Qods (private) hospitals with respect to mortality rate 24 hours of admission. Conclusion: Human, physical and training resources have not direct effect on decreasing mortality rate after 24 hours of admission but can create necessary conditions for providing higher quality services.

Background: Skin Sympathetic Response (SSR) is an electrophysiological technique and a central polysynaptic process. In mood disorders there are some changes in the cortex, hypothalamus activity, limbic system and basalganglia. Therefore, we compare the SSR changes in the patients with depression, mania and healthy persons. Methods and Materials: The patients with depression and mania were chosen based on DSM IV criterion by the psychiatrist. In cross-sectional analytic study, control group was selected away healthy men and women. The SSR was written by physiograph. The stimulat electrod was fixed on the middle finger of the left hand and 5 sympathetic responses were recored for every sample. The mean of amplitude, duration and latency time were computed and compared among three groups. Results: The mean of latency in control, mania and depressed groups were not statistically difference (p=.8). There were no difference between mean of duration in latency time in three groups. The mean of amplitude were not significant in three groups. Conclusion: It seems hypothalamus has not direct effect balance of sympathy skin responses.

Background: Skin cancer is one of the most important cancers in the world. This cancer is more common in men than women. We survey chromosomal changes in DMBA-induced skin cancer in SD rat strains. Methods and Materials: In this fundamental study, 20 SD rat strains were randomly divided into case and contal group. DMBA (2.5 mg) was injected to SD rat strains subcutaneously therefore skin cancer model for studies was created. Tumors became subjects for cell culture and metaphase chromosomal were prepared. Finally G-banding were stained. We have also transmitted genomic information from rat to human using suitable databases and Gene were determined. Results: Data showed numerical and frequent structural changes in different number of chromosomes. For example gain in chromosomes number 1, 15, 17 and loss in 1, 7, 15, and also structural changes like deletion was seen in chromosomes number 1, 4, 8, 10, 15, 17, and addition in chromosome number 15. Discussion: It is predicted that CST6، PRKCDBP، PTCH1، DKK3، ، BRMS1، CDKN1C، CD81، DMP1، CDKN2B ، EEF1A1 ، HRAS، CASP2، KLF4 probably cause skin cancer.

Background: Muscle mass is known to be a significant predictor of bone mineral density (BMD), and myostatin is a negative regulator of muscle growth. The aim of present study was investigate the effects of resistance training on bone mineral density and serum myostatin in healthy young men. Methods and Materials: In this clinical trial thirty young men were assigned to resistance training (n=15) and control (n=15) groups. The training group participated in 6 mounths of progressive whole-body resistance training. Total body fat, lean body mass, total body BMD, femoral neck BMD and L2-L4 spine BMD were determined by Dual-Energy X-ray Absorptiometry (DEXA) before and after 6 mounths of resistance training. Serum level myostatin measured by enzyme immnoassay. Results: Resistance training caused significant increases in chest press (52.36±6.36 vs 62.20±8.96 kg), leg press (135.24±13.77 vs 146.91±17.66 kg), lean body mass (61.00±0.96 vs 62.58±2.08 kg) and femoral neck BMD (1.115±0.078 vs 1.131±0.088 g/cm2), whereas myostatin were decreased (102.91±10.18 vs 94.03±13.93 ng/ml) (P<0.05). Total body BMD and L2-L4 spine BMD did not change with 6 months resistance training. Conclusion: A 6 month resistance training program increases muscle mass, power and improves BMD of the femoral neck in young men, and myostatin inhibition may play an important role in increasing BMD which is induced by resistance training.

Background: REM sleep has a role in memory processing. The period of post-learning, that REM sleep is higher than normal level and deprivation of REM sleep impairs memory, is called paradoxical sleep windows (PSW). Methods and Materials: In this experimental study, male N.M.RI rats were trained in a two-way shuttle avoidance task (100 trials/one sessions) then memory retention was tested in next week. In electrophysiology section, different sleep-memory factors were recorded in basal level and 1-4 hours after training. In behavioral section, animals that reached 70% learning criterion (learner group) were deprived of PS in the two periods of 1-4 hours and 5-8 hours after learning by Maze water technique. Results: The amount of REM sleep in group which gained 70% learning after 1-4 hours training, and group without it. In v.s of basic level, significantly increase (p0.01). Other factors were showed no significant difference between two groups before of training. In behavioral section those animals were deprived in 1-4 hr post-learning show significant memory impairment (p0.05). Conclusion: Paradoxical increased REM sleep is effective in memory consolidation after 1-4 hours training. This period can be consider as paradoxical sleep window.

Introduction: Cecal volvulus is an emergency surgical acute abdomen. In this condition cecum, ileum terminal and ascending colon becomes twisted on its mesenteric anticlock wise direction rotation ranging 180-360 degrees. The cecal volvulus is caused by a lack of fixation of cecum to retroperitoneum. The usual presentation consists of severe colicky abdominal pain with asymmetric abdominal distension. In this article two cases of cecal volvulus are presented. Cases: The first case was a 74 year old female which presented with sudden abdominal pain & asymmetrical severe distension following 3 days constipation. After Plain abdominal x-ray and abdominal CT scan, right hemicolectomy was performed. The second case was a 70 year old female who following 4 days constipation was presented with abdominal pain and distension. Supine and erect abdominal x-ray showed colon hyperaeration and multiple air-fluid levels. The gangrenous colon was resected and colostomy was done. Conclusion: Despite other causes of intestinal obstruction or sigmoid volvulus which can sometimes be treated medically, the treatment of cecal volvolus is always surgery and consisted of cecum and ascending colon resection.
