Background/Aims: The aim of this in vivo animal study was to evaluate the effectiveness and safety of dedicated cold snare (DCS)compared with those of traditional snare (TS) for cold snare polypectomy (CSP). Methods: A total of 36 diminutive (5 mm) and 36 small (9 mm) pseudolesions were made by electrocoagulation in the colons ofmini-pigs. Results: For the diminutive lesions, there were no significant differences in technical success rate, procedure time, or completeresection rate between the DCS and TS groups; the rate of uneven resection margin in the DCS group was significantly lower thanthat of the TS group. For small lesions, technical success rate and complete resection rate were significantly higher in the DCS groupthan in the TS group (100% [18/18] vs. 55.6% [10/18], p=0.003; 94.4% [17/18] vs. 40% [4/10], p=0.006). In addition, the procedureduration was significantly shorter, and the rate of uneven resection margin was significantly lower in the DCS group (28.5 sec vs. 66.0sec, p=0.006; 11.1% [2/18] vs. 100% [10/10], p<0.001). Two cases of perforation occurred in the DCS group. Multivariate analysisrevealed that DCS use was independently associated with complete resection. Conclusions: DCS is superior to TS in terms of technical success, complete resection, and reducing the duration of the procedure forCSP of small polyps.

Loading of NPS pollutant was valued through simulation by using BASINS/HSPF model which can simulate runoff volume in rainfall by time. For the verification of the model, it was analyzed the scatter diagram of the simulation value and measure value of water quality and runoff volume in Dongcheon estuary. Using the built model, a study on the time-variant characteristics of runoff and water quality was simulated by being classified into four cases. The result showed the simulation value was nearly same as that of the measured runoff, In the result of fit level test for measured value and simulated value, correlation of runoff volume was computed high by average 0.86 and in the water quality items, fit level of simulation and measurements was high by BOD 0.82, T-N 0.85 and T-P 0.79.

Mantle cell lymphoma (MCL) is a subtype of B-cell non-Hodgkin`s lymphoma (NHL), accounting for 3-10% of NHL. MCL involves the gastrointestinal (GI) tract in 10-30% of patients and common sites of MCL GI tract involvement are the colorectum and stomach, but any region of the GI tract may be involved. GI tract involvement by MCL usually presents in the form of multiple lymphomatous polyposis involving several segments of the GI tract. A few cases of MCL presenting with a GI tract stricture have been reported. Here, we present a rare case of a small intestinal stricture caused by MCL and review the literature of this disease.
