Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

A hybrid environmental control system was designed and built in the multi-greenhouses. After the hardware system was developed, the software was designed and constructed for this project. A software was adequate for reading data from many sensors and operating side windows, top windows, curtains and fans in the two greenhouses. Separate programs for control of the hardware, written Visual basic, Turbo-C and Assembler computer language, were developed to make the hybrid environmental control system operate. The program was a menu driven program within Windows environment. The initial menu was easily implemented by pressing a keypad key(KPK) on the keyboard or a mouse. Continued manipulation of the KPK or a mouse enable the user to reach easily any of the sub modes in the many modes. This software proved to be a reliable program for the hybrid environmental control system in the two greenhouse.

Intrathoracic goiter consist of two types, namely, the primary intrathoracic goiter and secondary intrathoracic goiter. Primary intrathoracic goiters are very rare. Fifteen to fifty percent of these patients are asymptomatic. Symptoms, when present, are usually the result of tracheal or esophageal compression. Standard chest roentgenograms are often diagnostic but computed tomographic or radioactive iodine scans may be helpful. In symptomatic patients or those in whom explorations are undertaken for diagnostic purpose or exclude carcinoma, surgical removal is indicated. We report here on a case that was completely removed with using the thoracoscopic assist technique. The postoperative courses were uneventful.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

우리나라의 농업은 작업자의 고령화와 여성작업자의 증가 그리고 비정형화로 구성된 작업형태로 인해 근골격계질환의 위험성이 매우 높은 업종이다. 특히 과수업은 작업점이 작업자의 머리위에서 형성되어 지속적으로 이루어지고, 수확기에는 작업량이 집중되어 농업분야 중에서도 근골격계질환의 유병율이 가장 높게 나타난다. 본 연구에서는 고령농작업자에게 집중적으로 발생되는 근골격계질환을 예방하기 위해 수확기에 집중되는 대표작업 세 가지 운반 작업, 선별작업 그리고 포장작업을 선정하여 유해요인을 분석하고 공학적 개선책을 제시하고자 한다. 배농업의 수확기 작업에서 근골격계질환 유해요인으로 나타나는 중량물 운반 작업과 불필요한 작업 자세를 개선할 수 있는 자바라 컨베이어 벨트와 높이조절식 작업대의 도입을 통하여 고령 작업자뿐만 아니라 여성 작업자들이 효율적인 시스템에서 안전하게 작업할 수 있기를 기대하며 근골격계질환 발생으로 인한 사회․경제적 손실도 감소시킬 수 있을 것이다.

Background: Some cases of QT interval, corrected QT interval (QTc), QT dispersion (QTd) and corrected QT dispersion (QTcd) have been reported in ESRD, but these results are variable and the influence of a hemodialysis is still controversial, In this study, we investigated the effect of hemodialysis on QT and QTc interval and QT and QTc dispersion in patients with ESRD 15 min before and 15 minute after each hemodialysis. Methods: Sixty-seven patients with ESRD (men 33 & women 34) on three-times stable hemodialysis (>3 months) were randomly enrolled. Fifty control subjects with a similar age and normal renal function were enrolled from this hospital. Routine biochemical studies were measured pre- and post dialysis, at the time of the ECG. Plasma Na+, K+, BUN, creatinine, ionized calcium and phosphate were checked. Twelve-lead electrocardiographs were performed at 10㎜/mv and 50㎜/s using a HewIett-Packard Pagewriter 100, before and after a single hemodialysis session.The QT interval was measured from the onset of the QRS complex to the end of the T wave. If the end of the T wave was not clear in a particular lead then it was excluded from analysis. When U waves were present, the end of the T wave was taken as the nadir between the T and U waves. Each QT interval was corrected for heart rate using Bazett's formula (QTc==QT/√(RR)) (ms). The difference between maximal and minimal QT interval duration was defined as QT dispersion (QTd) in each of the 12 leads. Result: This study demonstrates that QT, QTd, QTcd is higher in hemodialysis patients compared with control subjects, and QT and QTd rise postdialysis to levels comparable to those seen acutely following myocardial infarction, when patients are at greatly increased risk of potentially fatal ventricular arrhythmias, Conclusions: QT interval and QT dispersion, markers of risk for arrhythmias and sudden death, are elevated in hemodialysis patients, and rise postdialysis. QT interval and QT dispersion is an easily obtainable, noninvasive, simple, inexpensive, and widely available method of risk stratification in uremic patients receiving chronic dialysis. Additional studies are needed to clarity whether increased postdialysis QT dispersion results in an increased occurrence of arrhythmias.
