Background & Objective: Gastric cancer is the 2nd cause of cancer mortality after lung cancer. Approximately 12% of all cancer death are due to gastric cancer. Tumorgenesis is thought to be a multistep process involving a series of genetic changes in oncogenes and suppressor genes. The most common cancer-related genetic change known in human tumors is P53 mutation, particularly in gastric cancer. This study was done to determine P53 gene mutations in gastric cancer. Materials & Methods: This study was performed on 44 biopsy from patients with gastric cancer during 2002 in 3 hospitals in Tehran. For determination of P53 gene mutations was performed PCR-SSCP methods. Results: The patients group comprised 31 males and 13 females (Average age, 60.8 years Ranging from 34 to 84 years). 36 cases (81.8%) intestinal type, 5 cases (11.4%) were diffuse type and 3 cases no defined. 44 gastric cancers of gastric tissues were screened for the mutations of P53 gene mutations in exons 5-8 using the PCR-SSCP analysis. After polyacrylamide gel electrophoresis, 9 patients (20.5%) showed an apparent electrophoretic mobility shift between the cancer and other normal samples. One mutation in exon 5 (11.1%), 2 were detected in exon 6 (22.2%), 3 were found in exon 7 (33.3%) and 3 were detected in exon 8 (33.3%). The mutation rate was 7 of 36 (21.2%) in intestinal type and 2 of (40%) in diffuse type. No significant correlation between P53 gene mutations and age and genus was found.

Background & Objective: Rubella vaccine is prepared with live virus thus if it injects during abstinence period, it can cause fetal risks. The aim of study was to evaluate rubella IGM among infants of women who were vaccinated against rubella during 3 months pre-or post-conception (abstinence period). Materials & Methods: This cohort study was done on 253 mothers, including 116 mothers as cases and 137 mothers as controls. The case group inadvertently had received MR vaccine (RA27/3) during abstinence period. The control group selected randomly from similar delivery center that admitted for delivery. The background and confounding factors was matched between the control and case groups. In both groups after delivery, cord rubella IGM was measured by ELISA for serological diagnosis of infant infection. Data was analyzed by Chi-square and T-student tests. Results: The findings showed that the number of positive IGM infant was similar in both groups (One positive IGM in each group). In spite of no significant difference between the case and the control groups, the maximum theoretical risk in this study was 4.392% (RR=1.091 95% CI=0.271-4.392). Conclusion: Although no significant difference was found from the point of infants with an IgM+ serology in two groups, according to the risk ratio obtained in this study, we still recommend vaccination should be avoided during abstinence period.

Background and Objective: Ferula assa foetida (Ferula assa-foetida L.) is an herbaceous wild plant native to Iran which is used in the traditional medicine for treating stomach and intestinal disorders. This study was done to determine the antidiarrheal effect of hydroalcoholic extract of Ferula assa foetida in rat.

Methods: In this experimental study, Wistar adult male rats randomly allocated into negative control, positive control and interventional groups. Animals in negative control groups were recived normal salin orally. Animals in positive control groups were recived Atropine (0.1 mg/kg/bw) for evaluation of intestinal propulsive movement and Loperamide (3 mg/kg/bw) for evaluation of diarrhea. In interventional group 1, 2 and 3 animals were received hydroalcoholic extract of Ferula assa foetida 100, 200 and 400 mg/kg/bw, resepectively. One hour after administration of extracts and medicine diarrhea induced using castor oil in animals. Induced diarrhea, intestinal propulsive movement and intestinal fluid accumulation were evaluated in rats.

Results: Gavage of the extract (5 g/kg) did not produce any toxic effect in rats. The mean peristaltic index in Gavage for doses of 100, 200 and 400 mg/kg/bw, control and atropine groups was 97.00%, 65.88%, 62.23%, 86.19% and 52.86%, respectively. The extract at the lowest dose in combination with atropine was significantly reduced peristaltic index rather than of the atropin alone (P<0.05). The extract produced a non-significant reduction in the volume of intestinal fluid accumulation and propulsive movement in the castor oil-induced intestinal transit in rats. In a dose-dependent manner, the extract delayed the onset of diarrhea. Loperamide and highest dose of extract (400 mg/kg/bw) produced a significant reduction in the frequency of defecation and severity of diarrhea (P<0.05).

Conclusion: The hydroalcoholic extract of F. assa foetida showed anti-diarrheal activity due to its inhibitory effect on intestinal fluid accumulation.

Background and Objective: Electro convulsion therapy (ECT) is one of the most common ways for treatment of psychiatric disorders. The aim of this study was to compare the effect of Propofol, Etomidate, and Thiopental on seizure and recovery duration following ECT.
Methods: In this clinical trial study, 90 patients diagnosed with a psychiatric disorder by a psychiatrist, who need to be treated by ECT in 5 Azar hospital, Gorgan, north Iran. The patients were randomly divided into the three groups by simple random allocation method. Interventions included standard monitoring and pre-oxygenation with 100% FiO2 for 3 minutes for all patients in three groups. Anesthesia of the patients in the first, second, and third group was done with Thiopental (1.5 mg/kg), Propofol (0.6 mg/kg), and Etomidate (0.1 mg/kg), respectively. Administration of Succinyl Colin (0.5 mg/kg) as muscle relaxant and Atropine for prevention of bradycardia was uesd in all patients. Duration of seizure and recovery; changes in hemodynamic status including heart rate (HR) and mean arterial pressure (MAP); and amount of charge for ECT were recorded for each subject.
Results: Mean of seizure duration in Thiopental, Propofol, and Etomidate groups were 43.72±11.81, 35.74±10.58 and 45.81±17.26 seconds, respectively (P<0.05). Amount of charge for ECT in 3 sessions of treatment and changes of HR were not different between the 3 groups. Changes of MAP in the Propofol group was significantly less than other two groups (P<0.05). Recovery time following ECT was the least in Etomidate group in comparison with Thiopental and Propofol (P<0.05).
Conclusion: Ethomidate and Thiopental had the same effect on increasing seizure duration. However, due to the significant reduction in recovery time compared with Thiopental, Ethomidate may be considered as the best choice.
