A 5-month-old intact female Siberian Husky dog was presented for evaluation of severely enlarged maxilla. Abnormalities in CBC, serum chemistry and urinalysis indicated purulent inflammation and renal failure. Cytologic examination of the swollen maxilla showed a mixed population of multinucleated giant cells and round to polygonal to spindle shaped cells either individualized or aggregated. Both type of cells showed moderate anisokaryosis, and anisocytosis, prominent nucleolus or multiple nucleoli, and coarse chromatin. On histopathology maxilla and turbinate were diffusely expanded and replaced by variably dense fibrous connective tissue, and the kidneys showed changes consistent with renal dysplasia. Based on these findings, the diagnosis of fibrous osteodystrophy due to renal dysplasia and fibrosis was made. Despite the supportive care, the dog continued to decline and was euthanized.

A mechanical circulatory support system is a life-saving option for treating acute severe respiratory failure or cardiac failure. There are currently a few types of assist devices and the Twin-Pulse Life Support (T-PLS) system is a kind of pulsatile pump. We report here on three patients with severe life threatening cardiopulmonary dysfunction who had the T-PLS system used as an assist device. The indications for applying the T-PLS system were continuing respiratory or cardiac failure in spite of maximal ventilatory and inotropic support. There were two patients with acute respiratory failure due to infection and one patient with cardiac failure due to acute myocarditis. One respiratory failure patient and one cardiac failure patient survived after applying the T-PLS system for 3 days and 5 days, respectively. The T-PLS system is useful as an assist device and it should be considered before multi-organ failure occurs.

Objectives : WHW is a polyherbal medicine for the treatment of chronic renal failure (CRF). WHW previously reported various biological property such as anti-inflammation, anti-oxidation and anti-renal fibrosis in CRF. This study aimed to investigate the anti-apoptotic effect of WHW on staurosporin(SSP)-induced apoptosis in canine kidney epithelial cells (MDCK). Methods : MDCK cells were treated with different concentrations of WHW (0.1, 0.2, 0.5 and $1mg/m{\ell}$) for 1 h, and then induced apoptosis by treatment of SSP ($1{\mu}M$) for 24 h. Cell viability was measured by WST-1 assay. The expression of apoptotic proteins such as caspase-3, Bax and Bcl-2 was determined by Western blot. Caspase-3 activity and ROS levels were also measured by their commercial available assay kits. Cell apoptosis was observed by Hoechst and DNA fragmentation. Results : WHW significantly increased the cell viability on SSP-treated MDCK cells. WHW inhibited SSP-induced expression of apoptotic proteins such as caspase-3 and Bax, and significantly decreased caspase-3 activity in MDCK cells. WHW significantly decreased SSP-induced production of ROS, and suppressed SSP-induced chromatin condensation and DNA fragmentation in MDCK cells. Conclusions : These results suggest that WHW has an anti-apoptotic effect in renal cells through suppressing the expression of apoptotic proteins, ROS production and DNA damages.

The kidneys play a vital role in the maintenance of normal body fluid volumes and in the composition of the extracellular fluid compartments. There are normally more than 2 million functioning glomeruli that regulate total body water and solute concentrations. As renal failure progresses, there is a decrease in the number of functioning nephrons. Chronic renal failure(CRF) is the consequence of a multitude of diseases that cause permanent destruction of the nephron. Azotemia is an elevation in blood urea nitrogen(BUN) and serum creatinine levels subsequent to a decreased glomerular filtration rate(GFR), which results in uremia. This loss of renal function can cause functional and metabolic abnomalities of body. For this problem, oral & maxillofacial surgeons have demanded to routinely treat patients with CRF. However, there has not been a reported case of orthognathic surgery by bilateral sagittal split ramus osteotomy(BSSRO) in patients with CRF, which can cause multiple complications in healthy patients. We report developmental mechanism of complication associated with CRF and preop. and postop. care of orthognathic surgery by BSSRO in Cl III patient with severe chronic renal failure.

The purpose of this study was to analyze the nutritional status and dietary habits in predialysis patients of chronic renal failure(CRF). The patients group was composed of total 35 persons with chronic renal failure(diabetes exclusion), male 20, female 15 who were treated in the kidney internal department and the control group also composed of 35 persons, male 18, female 17 who were classified as normal by the medical examination. Their dietary habits, nutritional status and nutritional knowledge were investigated from two general hospitals in Inchon, middle of this year 2002. There were 31.4% of low weight patients (BMI below 20), 77.1% of anemia patients (serum hemoglobin below 12g/㎗), 6S.6% of hypertension patients with diastolic blood pressure over 90mmHg, 80% with systolic blood pressure over 140mmHg, 20% of hypercholesterolemia patients (serum cholesterol over 230mg/㎗), and 22.9% of hyperlipemia patients (serum triglyceride over 200mg/㎗). The cardiovascular disease seemed to be caused by the abnormality of lipid metabolism. The possibility of the bone disease was shown from patients of hyperphosphatemia (serum phosphorus over 4.7mg/㎗, 22.9%) and hypocalcemia (serum calcium below 8.4mg/㎗, 25.7%). Intake of insufficient calories which was caused by the lack of appetite affected on the nutritional status. The intake of most nutrients was not significantly different from the RDA for Koreans. Consequently, the patient groups took a lot of salt even after the diagnosis of CRF. But patients ate 6.lg of salt which were more than the recommended amount 2∼4g for patients with CRF. The patient groups, who had the experiences of nutritional counselling, had significantly higher nutritional knowledge related to CRF than control group. Unfortunately, patients could not have enough chances for nutritional counselling by the nutritionist even though they needed the nutritional informations and dietetic treatments. The continuous research is expected with regard to the detail plan for the improvement of nutritional support and the nutritional counselling because it is important to decide the requirements of nutrients for patients with kidney disease, considering the kidney function and status of nutrition.

This paper proposes algorithms that design the highly parallel multiple-valued logic circuit of DTG(Directed Tree Graph) to be represented by tree structure relationship between input and output of nodes. The conventional Nakajima's algorithms have some problems so that this paper introduce the concept of mathematical analysis based on tree structure to design optimized locally computable circuit. Using the proposed circuit design algorithms in this paper it is possible to design circuit in that DTG have any node number - not to design by Nakajima's algorithms. Also, making a comparison between the circuit design using Nakajim's algorithms and this paper's, we testify that proposed algorithms in this paper optimizes circuit design all case of DTG. Some examples are shown to demonstrate the usefulness of the circuit design algorithm.

Characteristics of ground-penetrating radar(GPR) signals for detecting buried pipes are investigated numerically. Transmitting and receiving parts of a GPR system, a subsurface soil and a plastic pipe filled with a dielectric material are modeled by using the finite-difference time-domain(FDTD) method. FDTD simulations for observing aspects of GPR signals are performed as a function of the diameter of the pipe and the permittivity of the filling material in the pipe. GPR signals scattered by a dielectric filled pipe appear as a superposition of two waves, such as the specular wave from the front convex surface of the pipe and the axial wave from the rear concave surface of the pipe. We show that the amplitude, the polarity, the delay time of two waves depend on the size of the pipe and the permittivity of the filling material in the pipe.

TPMS(Tire Pressure Monitoring System) using the wireless communication technique is defined as the safety aid system to efficiently realize and manage the condition of tires in the vehicle. The wireless communication system of TPMS should suffers from various noise and interferences such as signals of each tire sensor or outside electrical equipments. In order to retain the data reliability of TPMS, we propose an assessment method of the data reliability based on signal-to-interference and noise ratio (SINR) of the received signal. The proposed technique can be widely applied to wireless duplex communication systems based on various sensors. We verify critical SINR values to satisfy data reliabilities of 95%, 97%, and 99% through computer simulation.

Inferior vena cava filters are increasingly being used as an alternative to anticoagulation therapy for the prevention of pulmonary embolism. However, using an Inferior vena cava filter may result in clinically significant complications. Phlegmasia cerulea dolens is a rare disease that presents with acute complete venous occlusion due to extensive thrombosis in the lower extremity. It is characterized by intense pain, edema, decreased pulses and a cyanotic extremity. We report here on a case of phlegmasia cerulea dolens that was accompanied with disseminated intravascular coagulation (DIC) as a complication of the placement of an inferior vena cava filter in a patient who had been previously diagnosed with pulmonary embolism, and the patient had recently developed a cerebral hemorrhage due to a traffic accident.
