  • To improve conventional yeast one-hybrid screening, we have developed an efficient mammalian one-hybrid system that allows rapid isolation of com-plementary DNAs which are able to induce human p14$^{ARF}$. tumor suppressor gene. A 1.5 kb promoter region of p14$^{ARF}$ was fused to EGFP to generate ARF promoter-EGFP reporter vector. This reporter plasmid was stably trans-fected into NIH3T3 cells for generation of reporter cell line. When the reporter cell line was infected with E2F-1 together with excess amounts of empty vector, the cells that received the positive modulator were readily identifiable by green fluorescence using FACS. The GFP-positive cells were cloned directly from the cultured cells and expanded in bulk culture. The genomic DNAs from GFP-positive cells were prepared and the CDNA insert in integrated retroviral genome was recovered by PCR using primers annealing to the retroviral vector sequences flanking the insert-cloning site. This system should be useful for efficient screening of expression CDNA libraries in mammalian cells to identify novel upstream regulators for spe-cific genes by one-hybrid interaction.ion.

  • Purpose : This study was to observe the nephroprotective effects of the traditional prescription, Daebuncheong-eum (DBCE). DBCE has generally been used for treating various renal diseases, including renal failure. Methods : Three different dosages of DBCE extract were orally administered once a day for 28 days. At the 23rd day after DBCE extract treatment, cisplatin was also treated. Then, 5 days after cisplatin treatment, all rats (6 groups of 8 rats each) were sacrificed. Changes on the body weight, kidney weight, serum BUN and creatinine levels were observed, along with changes to the kidney MDA and GSH contents. The results were compared with captopril 100mg/kg, from which the effects on cisplatin-induced acute renal failures have already been confirmed. Results : Cisplatin induced ARF are induced by oxidative stress and related lipid peroxidation in the present study. However, these ARFs and inhibition of antioxidant effects induced by cisplatin were dose-dependently reduced by treatment of all three different dosages of DBCE extracts. Conclusion : This study suggests that DBCE extracts show favorable effects on cisplatin-induced rat ARF.

  • Rhabdomyolysis is a syndrome involving the breakdown of skeletal muscle causing myoglobin and other intracellular proteins and electrolytes to leak into the circulation. There are various causes of acute rhabdomyolysis in childhood, such as direct trauma to muscle, muscle necrosis from ischemia, inflammation in muscle, or exposure to drugs and toxins. The most-important complication of this disorder is acute renal failure (ARF). However, the contributing factors to the development of ARF in children with rhabdomyolysis remain obscure. We report two cases of rhabdomyolysis after excessive exercise.

  • Purpose : Acute renal failure (ARF) is an important complication of rhabdomyolysis. The purpose of this study was to identify the major causes of rhabdomyolysis in children and to identify the factors associated with the developmet of ARF. Methods : A retrospective chart review between January 1997 to June 2005 was conducted of 60 patients with a diagnosis of rhabdomyolysis. Rhabdomyolysis was defined by an elevation of serum creatine phosphokinase (CK) greater than 1,000 IU/L with a MM fraction more than 95% or serum myoglobin>300 mg/dL or positive urine myoglobin. Patients were excluded if they had evidence of myocardial ischemia, or cerebrovascular insufficiency. Results : Sixty patients (37 males, 23 females) were enrolled, with the median age of 4.25 year. The most common causes of rhabdomyolysis were repiratory tract infection (9), seizure (7), hypoxia or asphyxia (6). Fifteen patients (25.0%) developed ARF and ten of them (66.0%) died. The initial serum creatinine, uric acid, potassium, pH and peak serum creatinine, initial systolic blood pressure, and mental status were statistically correlated with the development of ARF. The peak serum CK was associated with mortality of rhabdomyolysis. Conclusion : Acute renal failure was significant complication of rhabdomyolysis in children. Several clinical and laboratory factors were statistically associated with the development of ARF and death.

  • Acute renal failure (ARF) is a common postoperative complication after the cardiac surgery. Postoperative ARF have various causes, and are combined with other complications rather than being the only a complication. It deteriorates the general condition of the patient, and makes it difficult to manage the combined complications by disturbing the adequate medication and fluid therapy. We have planned this study to evaluate the effects of postoperative ARF after the on-pump coronary artery bypass surgery (CABG) on the recovery of patients and identify the risk factors. Method and Material: We reviewed the medical records of patients who underwent CABG with cardiopulmonary bypass by a single surgeon from Jan. 2000 to Dec. 2002, We checked the preoperative factors; sex, age, history of previous serum creationism over 2.0 mg/㎗, preoperatively last checked serum creatinine, diabetes, hypertension, left ventricular ejection fraction, intraoperative factors; whether the operation is an emergent case or not, cardiopulmonary bypass time, aortic cross clamp time, the number of distal anastomosis, postoperative factors: IABP. Then we have studied the relations of these factors and the cases of postoperative peak serum creatinine over 2.0 mg/㎗. Result: There were 19 cases with postoperative peak serum creatinine over 2.0 mg/㎗ in a total 97 cases. Dialysis were done in 3 cases for ARF with pulmonary edema and severely reduced urine output. There were 8 cases (42.1%) with combined complications among the 19 patients. This finding showed a significant difference from the 5 cases (6,4%) in the patients whose creatinine level have not increased over 2.0 mg/㎗. The mortalities are different as 1.3% to 10.5%. The risk factors that are related with postoperative serum creatinine increment over 2.0 mg/㎗ are diabetes, the history of previous serum creatinine over 2.0 mg/㎗ and left ventricular ejection fraction. Conclusion: Postoperative ARF after the on-pump CABG is related with preoperative diabetes, the history of previous serum creatinine over 2,0 mg/㎗ and left ventricular ejection fraction. Postoperative ARF could De the reason for increased rate of complications and mortality after on-pump CABG. Therefore, in the patients with these risk factors, the efforts to prevent postoperative ARF like off-pump CABG should be considered.

  • This paper presents a fuzzy data fusion scheme which can analyze the sensor condition, the strength and location of a force applied to a test material. These can be realized by the modelling and fusioning of sensor signals and sensor properties. The technique uses, as the inference variables, relative magnitude of data (RMD), absolute magnitude of data (AMD) initial state (IS), synchronized relational function (SRF) and asynchronized relational function (ARF). To show the usefulness of this scheme, an experiment on the cantilever bar and six strain gages is carried out. The location of the force is inferred from SRF and ARF and the strength from RMD and AMD. In particular, the strength is compared with the measurement data of the force sensor.

  • Nowadays, in spite of the remarkable development of the results of open heart surgery, the incidence of postoperative acute renal failure [ARF] has been increased due to the expansion of the candidates and prolonged operation time for complicated cases. It is also well known that ARF after open heart surgery, if once occurred, is a critical complication, therefore early diagnosis and treatment about it are very important for prognosis. Recently a low molecular weight [2 * microglobulin [[2* MG]has been used as a indicator of renal function. Because of the properties of [2 * MG, serum concentration of it is increased in glomerular dysfunction and urine excretion of it is increased in tubular dysfunction. Author studied about the perioperative changes of serum [2* MG and BUN concentration in 25 children and 30 adults for evaluation of significances of [2* MG as a parameter of postoperative renal function in open heart surgery, and the results were obtained as follows. l. In open heart surgery, the serum [2* MG concentration was elevated postoperatively in the all cases from the first postoperative day. 2. There were a significant correlation between the preoperative BUN and [2* MG concentration [P< 0.01]. The correlation factor[r] in child group was 0.8512, and in adults 0.8636. 3. The maximum level of serum [2* MG in the both child and adult groups were noticed in 4th postoperative day as 2.61*0.80mg/ 1 in child group and 3.39*1.47 mg/ 4 in adult group, and there was a significant difference between the two groups statistically[P < 0.05]. 4. The pattern of changes of serum concentration of [2* MG with time was very similar with the changes of BUN, but in a case of ARF [expired with it] the changes of [2* MG was more remarkable. 5. There was a significant differences in the maximum level of [2* MG between the 2 group according to the ECC time [groups of below and above 60 minutes] [P< 0.01].

  • Many dialysis modalities such as peritoneal dialysis (PD), hemodialysis (HD) and continuous hemofiltration or hemodialysis (CRRT) are available for the management of pediatric patients with acute renal failure (ARF). PD is a relatively simple, inexpensive modality and can be used in hemodynamically unstable patients. But, it may not be the optimal therapy for patients with severe volume overload or life threatening hyperkalemia. HD is the preferred modality for the treatment of severe volume overload, severe hyperkalemia, but it needs vascular access. Improvements in the HD equipment have allowed HD to be performend in small children. Recents technological improvements in CRRT therapies have enabled pediatric patients who are less stable to be treated. CRRT is becoming the preferred method of acute therapy in pediatric intensive care units. A sound knowledge of the underlying principles of dialysis and awareness of recent technological advancements in differnet dialysis modalities will hopefully result in improved management of children with ARF.

  • The patient with group A beta-hemolytic streptococcal infection and articular disease who does not fulfill the modified Jones criteria for a diagnosis of acute rheumatic fever(ARF) have been classified as poststreptococcal reactive arthritis/arthralgia. A 10-year-old girl had presented with fever and arthralgia. She had pain in her left knee for 7 days but no swelling. A throat culture showed no growth but antistreptolysin O titer and C-reactive protein were elevated. A clinical follow up one month later showed neither arthralia nor sequelae as acute rheumatic fever. Poststreptococcal reactive arthritis/arthralgia seems to be part of the disease spectrum of ARF and to prevent subsequent development of ARF and carditis in these patient, it is recommended that antistreptococcal prophylaxis should be administered for 1 year and then could be discontinued if there is no evidence of cardiac involvement.
