| 1 | Colonoscopic evaluation of minimal rectal bleeding in average-risk patients for colorectal cancer显示文摘AIM: To assess the prevalence of clinically signifi cant lesions in patients with minimal bright red bleeding per rectum (BRBPR). METHODS: Consecutive outpatients prospectively underwent colonoscopy at Loghman Hakim Hospital, Tehran. Minimal BRBPR was defi ned as small amounts of red blood after wiping or in the toilet bowl. Patients with the following alarm signs were excluded: Positive personal history of colorectal neoplasms or inflamma-tory bowel disease (IBD), positive fi rst degree family history of colorectal neoplasms, history of altered bow- el habits, recent signifi cant weight loss, and presence of iron defi ciency anemia. Neoplastic polyps, colorectal carcinoma, and IBD were def ined as signif icant lesions. RESULTS: A total of 402 patients (183 female and 219 male, aged 43.6 ± 15.7 years) were studied. Hemorrhoids (54.2%), anal fi ssures (14.2%) and ul-cerative colitis (14.2%) were the most common lesions and colonoscopy was normal in 8.0%. Signifi cant le-sions were found in 121 (30.1%) patients, including 26 patients (6.5%) with adenocarcinoma and 30 (7.5%) with adenomatous polyps. Almost all patients with signifi cant lesions had at least one lesion in the distal colon; an adenocarcinoma and an adenomatous polyp in the proximal colon were found in 2 patients with hemorrhoids. CONCLUSION: Flexible sigmoidoscopy appears to be sufficient for the evaluation of average risk patients with minimal BRBPR. Rigid sigmoidoscopy may be used as an alternative in patients less than 40 years of age in settings where the former is not available. Thechoice of colonoscopy over flexible sigmoidoscopy in patients aged over 50 years should be individualized. | Shahriar Nikpour Ali Ali Asgari | 2008 | World Journal of Gastroenterology2008，14，42： | 6 |

| 20 | Evaluation of bioefficacy ofα-cypermethrin in long lasting impregnated net(Interceptor~) using analytical method显示文摘Objective:To evaluate relationship betweenα-cypermethrin residues in Interceptor~? nets by using HPTLC methods and mortality percentage in standard WHO’s method 'cone test' after repeated washings.Methods:Interceptor~? containingα-cypermethrin was provided by BASF Company.The washing procedure and bioassay tests were carried out according to the WHO-recommended methods.Malaria vector,An.stephensi was exposed to impregnated bed net for three minutes and then mortality measured after 24 hour recovery period.Chemical analysis was carried out in chemical laboratory by using high performance thin layer chromatography method.Results:Result of cone bioassay method showed that washing reduced the efficacy of Interceptor~? bed net from 100%in unwashed nets to 15%at 20 washes.After 20 washes,nets contain(61.2±2.8) mg/m^2 resulting 15%mortality in cone test.Killing activity was reduced when nets were washed.Conclusions:Results will provide an essential clue for monitoring and evaluation of bioefficacy of any long lasting impregnated bed net for quality control.Findings of this study will be useful for WHO.local investigators and people who wish to use pyrethroid-impregnated bed nets for malaria vector control. | Vatandoost Hassan Mamivandpoor Hossein Shayeghi Mansoreh Abai Mohammad Reza Yaghoobi-Ershadi Mohammad Reza Raeisi Ahmad Abtahi Mohammad Rafie Fatemeh Nikpour Fatemeh | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，8： | 1 |
