Castlemam's disease is an asymptomatic and benign lymph node hyperplasia which is frequently manifested as mediastinal mass in over 70% of cases. Amyloidosis is rarely associated with Castleman's disease. Recently we experienced a patient with nephrotic syndrome due to renal amyloidosis who had been previously diagnosed as Castleman's disease of retroperitoneal lymph node enlargement. A 47-year old woman was admitted because of generalized edema and chest tightness. Five months ago she diagnosed as Castlman's disease-plasma cell type, of retroperitoneal lymph node enlargement. The patient was followed up through outpatient department without any specific medication. Physical examination showed pale conjunctivae, palpable mass on epigastric area and pretibial pitting edema. The hemoglobin, leukocyte count and erythrocyte sedimentation rate were 96 g/L, 5.9×109/L and 127 mm/hour, respectively. The blood urea nitogen was 3.6 mmol/L and creatinine was 88 umol/L. The urinalysis showed 3 positive for albumin. Twentyfour hour urine contained 16.6 grams of protein. A computerized tomographic (CT) scan of the abdomen disclosed multiple lymph node enlargement at mesentery. Percutaneous needle biopsy of kidney showed massive infiltration of pale pinkish amorphous material in the glomerular tuft forming large nodules. Ultrastructural examination exhibited heavy deposition of amyloid fibrils in the mesangium and perpendicular to glomerular basement membrane. Polarizing microscopy with Congo-red stain revealed prominent yellow green birefringence in glomeruli, tubules and interstitium.

Vitek system, a fully automated in vitro testing system designed for identification and antimicrobial susceptibility test of microorganisms was introduced to The Seoul National University Hospital in 1985. Principal advantages of using this system are rapid identification of microorganisms and rapid reporting of the minimal inhibitory concentration values. Using Vitek system, 248 isolates from culture requested blood specimen in our hospital from April 11. 1991 to August 31. 1991 were identified and minimal inhibitory concentration test were performed. We summarized the data and obtained results as below. 1. 52.3% of catalase +, Gram ( +) cocci, 75% of catalase(-), Gram(+) cocci, 74.8% of Gram (-) glucose fermenters and 57.1% of glucose nonf ermenters were identified within 9 hour. 2. Mic values of 87.6% of Gram ( +) cocci ( catalase +,- ) and 86.6% of Gram ( - ) rods (glucose fermenters and nonfermenters) were obtained within 9 hour. 3. 32.5% of isolated organisms were reported within the test performed day by using Vitek system.

Two experiments were conducted to investigate the effect of dietary supplementation of plant phytase(Phytazyme^R) in corn-soybean meal based diets on utilization of phytase-bound phosphorus in laying hens and evaluate nitrogen(N) digestibility and phosphorus(P) availability in breeders. In he experiment one, three levels of the Phytazyme^R(0.05, 0.1, and 0.2% of diet) were added to diets containing a half of control TCP level(0.96%) for 4 wks. Feed consumption, egg production rate, egg weight and eggshell quality were recorded weekly. At the end of experiment, 8 birds per treatment were sacrificed, liver weight were weighed and right tibiae were removed for determination of P content. The second experiment was conducted to evaluate the P availability and nitrogen digestibility in breeders fed same diets for 2 wks. Feed and excreta were collected to determine the P and N contents for the last three days of experiment two. Addition of Phytazyme^R resulted in no effects on feed intake, egg product rate, egg weight and egg shell quality. P excretion decreased and its availability enhanced as phytase supplementation increased in diets. Dietary supplementation of Phytayme ^R above 0.1% level in corn-soybean meal based diets did not have an adverse effect on production and decreased level of phosphorus in excreta.

TMS320C31칩을 사용한 산업용 로보트의 실시간 적응제어기 설계
한성현(S. H. Han),김용태(Y. T. Kim),이만형(M. H. Lee),김성권(S. K. Kim),김진오(J. O. Kim) Korean Society for Precision Engineering 1996 한국정밀공학회지 Vol.13 No.10
This paper presents a new approach to the design of adaptive control system using DSPs(TMS320C31) for robotic manipulators to achieve accurate trajectory tracking by the joint angles. Digital signal processors are used in implementing real time adaptive control algorithms to provide an enhanced motion control for robotic manipulators. In the proposed control scheme, adaptation laws are derived from the improved Lyapunov second stability analysis method based on the adaptive model reference control theory. The adaptive controller consists of an adaptive feedforward controller, feedback controller, and PID type time-varying auxiliary control elements. The proposed adaptive control scheme is simple in structure, fast in computation, and suitable for implementation of real-time control. Moreover, this scheme does not require an accurate dynamic modeling, nor values of manipulator parameters and payload. Performance of the adaptive controller is illustrated by simulation and experimental results for a SCARA robot.

N/A Radionuclide renal scintigraphies were performed in a 24-year-old man with right renal artery branch stenosis. Captopril enhanced Tc-99m-DTPA renal scintigraphy revealed no abnormal finding in the right kidney But, Tc-99m-DMSA renal scintigraphy showed regional cortical photon deficient area corresponding to the area supplied by the stenotic branch artery. The defect size increased in captopril enhanced Tc-99m-DMSA renal scintigrphy and nearly disappeared after successful transluminal renal angioplasty. This case suggests that the captopril enhanced Tc-99m- DMSA renal scintigraphy may be a useful method in the evaluation of renovascular hypertension, especially due to branch renal srtery stenosis.
