각종 질소·인 제거공정에서 도출된 미생물 성장 동역학 계수 비교 분석
임세호,고광백,오영기 한국물환경학회 2004 한국물환경학회지 Vol.20 No.6
In this study, some of bacterial growth kinetic parameters were delineated and evaluated for the biological nutrient removal processes such as the A²/O, 4stage-BNR, Intermittent Cycle Extended Aeration System(ICEAS) and Intermittently Aerated Cylindrical Oxidation Ditch(IACOD) processes. Y_H values for the ICEAS process ranged from 0.71 to 0.74, and were higher than those for the other processes. It seems to indicated that organic carbons uptaked by microorganism were more used up for cell synthesis rather than for energy components in the ICEAS process. b_H for the ICEAS and IACOD processes were lower than those for A²/O and 4stage-BNR processes. The μ_(max·A) for the ICEAS was higher than those for the other processes, which indicated that desirable operating conditions for nitrifying bacteria's growth were established.
새로운 항암성 백금(Ⅱ) 착체류의 in vivo 독성연구
정광원,임종석,정세영,노영수,최병기 한국환경독성학회 1995 환경독성보건학회지 Vol.10 No.2
The general toxicological study of new platinum(Ⅱ) compounds, KHPC-002, KHPC-005 and KHPC-006 were investigated in rats. The effects of these Pt(Ⅱ) complexes on renal, hematopoietic and hepatic system in rats showed lower toxicity compared with cisplatin. In the consideration of the maximal dose of these Pt(Ⅱ) complexes using in this experiment is 4-8 times higher than cisplatin, these novel compounds will have the less general toxicity in vivo.

This study was conducted to investigate productivity and nutrients uptake of Sorghum×Sudan grass (SSG) and Italian ryegrass (IRG) cropping system with cattle manure compost and liquid pig manure application, respectively. Changes in mineral N and available P concentration before and after each cropping were also examined. Dry matter yield ranged from 2.12 to 2.86 ton ha-1 for SSG and from 3.57 to 6.08 ton ha-1 for IRG. Forage productivity observed in this study was substantially lower than other studies probably due both to low precipitation during cropping season and to soil characteristics; lower pH (<5) and available P concentration (ranged from 98.6 to 174.8) than the soils used in the previous studies. The uptake of N and P also showed very similar pattern to dry matter yield; IRG had higher nutrients uptake than SSG. According to nutrient balance analysis, 76.4% of N and 76.9% of P2O5 applied to the fields (161 kg N ha-1 and 265 kg P2O5 ha-1) were not assimilated by SSG. For IRG, 50.2% (133 kg N ha-1) of N applied (265 kg N ha-1) was not taken up; meanwhile, the amount of P2O5 assimilated by IRG was 75 kg P2O5 ha-1, and this was 49 kg P2O5 ha-1 more than that of applied P2O5 (26 kg P2O5 ha-1) as liquid manure, indicating additional P uptake from the soils. Accordingly, mineral N (NH4 + and NO3 -) and available P concentrations of the soils increased after SSG harvest as compared with the soils before cultivation, but they decreased after IRG cultivation. Such differences in nutrient uptake by plant and soil nutrient availability could be attributed to the contrasting availability of nutrients in the compost and liquid manure. Organic forms of nutrients included in the compost is likely to be released slowly by decomposition of organic matter and thus the nutrients released could be utilized by the next crop (IRG) rather than by the crop (SSG) to which compost was applied. On the other hand, as most nutrients in liquid manure is readily available, N and P in the liquid manure could be assimilated by IRG. Therefore, it might be necessary to consider both compost (slowly available) and liquid manure (rapidly available) to achieve a goal production of forage.

The mass treatment trial of pyrantel pamoate on Ascaris lumbricoides and Ancylostoma duodenale infections was carried out to school-children and inhabitants in rural areas in the central part of Korea. Pyrantel pamoate ("Combantrin") tablet (123 mg base) was administered as a single dose of 10. 0 mg per kg. body weight to a total of 4,198 Ascaris infected cases selected out of 4,436 (41. 6%) positives, who were screened from the total 10,660 collected stool specimens. Of these, only 3,169. cases were followed up after treatment to provide an analysis in this study. Incidentally 161 cases with concomittently infected hookworm were also subjected to assess the efficacy of pyrantel pamoate against A. duodenale. The egg negative conversion rate on A. lumbricoides was 95.3%, and on A. duodenale, 97.5% four weeks following treatment. In failed cases, the egg reduction rates on both of the infections were 97.6% and 97.3% respectively. No side effects and no problem in drug administration were demonstrated. It is concluded that this study confirms the high efficacy of pyrantel pamoate in the treatment of Ascaris lumbricoides and Ancylostoma duodenale infections and also proves the acceptability and safety of this drug in the mass treatment of ascariasis in a population with relatively high worm burden.

Running title: Cases of anesthesia for extremely low birth weight infant. Extremely low birth weight infants (birth weight < 1000 g) are prone to various morbidities such as respiratory distress syndrome, intraventricular hemorrhage, periventricular leukomalacia, patent ductus arteriosus, necrotizing enterocolitis and retinopathy. To accomplish successful anesthetic management, many precautions must be continuously taken during the operation. First, inspired oxygen concentration should be adjusted to avoid oxygen toxicity. Second, body temperature must be maintained adequately. Third, hemodynamic parameters should be kept stable. We report 2 cases of successful anesthetic management for extremely low birth weight infant who underwent ligation of patent ductus arteriosus at the neonatal intensive care unit.

저자들은 56세 여성 환자의 왼쪽 쇄골 하 정맥에 시행한 이식형 약제주입기 카테터의 삽입 후 발생한 비정상 위치에 대한 증례를 보고하고자 한다. 카테터의 끝은 환자의 늘 어진 가슴, 체위, 신체의 움직임, 카테터의 유동성 등의 영향으로 천자된 정맥 내에서 견인되고 뒤쪽으로 이동하였다. 환자는 어떠한 증상도 호소하지 않았지만 비정상 위치의 카테터는 심각한 합병증을 유발할 수 있기 때문에 제거되었다. 따라서 시술자는 약제주입기 삽입 전에 환자의 신체 상태와 단순 흉부 촬영상을 확인하고 카테터의 비정상 위치가 발생할 수 있는 위험 징후를 알아차려야 하겠다.

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.

Objective : There are controversies in pnmmg technique of rocuronium whether it can or can't shorten the onset time. We want to compare the effects of two different priming doses and intervals of rocuronium. Materials and Methods : After giving propofol, 50 patients were randomly assigned to 5 groups. Group I received a placebo, followed 3 min later by rocuronium 0.6 mg/kg. Priming doses and intervals of Group II, Ill, N, V were 0.06 rng/kg and 2 min, 0.12 mg/kg and 2 min, 0.06 rug/kg and 3 min, 0.12 mg/kg and 3 min, respectively. Total dose of rocuronium was 0.6mg/kg. Train of four (TOF) count or ratio and 1st twitch height of TOF (T1) were monitored with 15 secondsintervals. TOF ratio of each groups just before bolus injection, duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were compared. Results : Duration for TOF count to reach zero and duration for Tl to reach 95% depression after bolus injection were decreased in priming groups compared to Group 1 (P < 0.01) In group V, significant depression of TOF ratio just before bolus injection was seen (P < 0.05). Conclusion : Priming technique with rocuronium is effective method to shorten the onset of neuromuscular block. But priming dose of rocuronium itself could cause hypoxia and aspiration in awake patients and should be used carefully. Priming dose of rocuronium 0.06 mg/kg and 2 minutes interval maybe relatively safe method.
