Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

There are several methods for the reconstruction of partial urethral defect, including split-thickness skin graft, full-thickness skin graft, and preputial flap and free flap. Despite partial success using these methods, most results are unsatisfactory due to frequent complications such as postoperative infection, fistula formation, hair growth and stricture. There have been several pioneering experiments in this field using autogenous vein graft and the results have been controversial. However, the fact that the endothelial lining is replaced by natural urethral epithlium is generally accepted as a positive effect of this method. This experiment was designed to identify the possibility of using vein graft for the reconstruction of partial urethral defect. Two different types of vein graft method were performed in a total of 20 New Zealand White rabbits with partial urethral defect. Firth, for the patch-graft group, a 1×1 cm rectangular vein graft was sutured at a defective area of the same size. Second, for the tubed-graft group, a vein graft segment 1 cm long was replaced at a segmental urethral defect of the same length. Histologic study was performed at three and eight weeks postoperatively in each group. The process of transitional ell epithelial replacement within the grafted vein was uniformly observed in both experimental groups at three weeks postoperatively. At eight weeks postoperatively, the epithelial replacement was almost complete and histologically undistinguishable. In the retrograde urethrogram performed after 8 weeks, the urinary flow in the patch-graft group was normal and showed no stricture, and two of five rabbits in the tubed-graft group showed partial stricture at the graft site. In conclusion, natural urethral epithelium was restored in grafted venous segments irrespective of the type of graft. Partial stricture was observed in 40% of the tubed-graft group while complete reconstruction was possible in the patch-graft group.

For the efficient determination of activity against solid tumors, an in vitro tumor model that resembles the condition of in vivo solid tumors, is required. The purpose of this study was to establish a rapid culture method and viability assay for an in vitro 3-dimensional tumor model, multicellular spheroid (MCS). Among 12 human cancer cell lines, a few cell lines including DUD-1 (human colorectal carcinoma cells) formed fully compact MCS which was adequate for in vitro viability assay. DLD-1 MCS showed steady growth reaching 700 pm diameter after 11 day culture. DUD-1 cells grown as MCS showed significant increase in G_(0)/G₁ phase compared to the monolayer cells (73.9% vs 45.7%). but necrotic regions or apoptotic cells were not observed. The cells cultured as MCS showed resistance to 5-FU (10.3 fold higher IC_(50)) compared to monolayers. however, tirapazamine (a hypotoxin) showed similar activity in both culture systems. In summary, MCS may be a valid in vitro model for activity screening of anticancer agents against human solid tumors and also exploitable for studying molecular markers of drug resistance in human solid tumors.

인삼이 밀가루의 아밀로그래프에 의한 호화 성질과 파리노그래프에 의한 반죽 성질에 미치는 영향을 조사하였다. 인삼첨가 LL면의 조직감과 관능적 특성에 미치는 영향을 분석하기 위하여 밀가루에 대하여 인삼을 5.0∼10% 첨가하여 LL면을 제조한 뒤 면의 조직 특성 분석 및 조리시험을 하고 관능검사를 하였다. 인삼을 첨가하면 아밀로그래프의 호화개시 온도를 3.1℃ 지연시켰으며, 최고 점도를 40B.U 감소시켰다. 파리노그래프의 흡수율은 1.2% 증가하였으며, 반죽의 안정도는 인삼의 첨가로 2.0분 길게 측정되었다. Hunter L값은 인삼 첨가량이 증가할수록 낮아졌으며, Hunter a, b값은 반대로 측정되었다. 인삼첨가 LL면의 층밀림 압출력은 첨가량의 증가에 따라 높아져 10.0%의 첨가는 대조구 18.65(㎏f)보다 2.3(㎏f) 높은 23.95(㎏f)로 측정되었으며, 경도도 대조구보다 5.4(㎏f) 높게 측정되었다. 인삼첨가 LL면의 무게 증가는 인삼의 첨가량이 증가할 때 다소 높게 나타났으나. 부피 증가는 오히려 높게 나타나 조직이 다소 치밀한 것으로 나타났다 용출량은 인삼량의 증가에 따라 약간 감소하였다. 미생물은 인삼의 첨가량이 증가할수록 줄어들어서 장기 저장이 가능하였다. 관능 검사 결과는 인삼첨가 LL면이 4.2 및 4.0으로 비교적 좋은 점수를 얻었다. 이같이 LL면 제조시 인삼 첨가량은 7.0%의 수준이 효과가 컸다. The influence of ginseng on the paste or gelatinization properties by amylograph and mixing properties by farinograph of wheat flour, and on quality properties, color, cooking quality, textural and sensory properties, and reducing microbial population of LL (Long Life) noodles was studied. The contents of ginseng used were from 5% to 10% based on flour weight. The viscosity property of wheat flour with ginseng was increased the initial pasting temperature but the amylograph peak viscosity were decreased in vice versa. The farinograph absorption, stability and breakdown were increased by ginseng. The whiteness of LL noodles manufactured with ginseng was lower than that of control. The shear extrusion force and hardness of LL noodles manufactured with ginseng were shown much higher value than those of control. At cooking quality examination of LL noodles manufactured with ginseng, weight of cooked LL noodles was decreased but volume was appeared in vice versa. Extraction amounts of LL noodles manufactured with ginseng during cooking were much smaller than those of control. Total counts of microorganism of LL noodles manufactured with ginseng were decreased during storage at 30℃. Sensory properties of cooked LL noodles which was manufactured with ginseng showed quite acceptable. Based on the cooking and sensory evaluation test, addition of 7.0% ginseng to wheat flour may be suitable for processing LL noodles.
