By the increase of the rate of existence of the hemodialyzing patients, they were required the long run treatment. Regardless of medical insurance expansion, hemodialyzing cost much expenses so that hospital has been considering the reuse of hemodialyzer and flowing euqipments along with the diverse study and progress of the ways of hemodialyzing and medical instruments. This study was aimed to provide the basic materials regarding the reuse of hemodialyzer which is used for the patients of chronic renal disease. The reusing program in the artificial kidney center of K hospital has been used for this study from 50 patients aften one year result from Sep. 1995 through Aug. 1996. Automatic equipment of DRS-4 made by Seratronic Co., was used as the equipment and it was retreated with the function test simultaneously. Compliaction and confirmation of the infection were by the records of the hemodialysis of the patients. SPSS was used for the analysis of the materials by computerization. The character of the patients and the rate of removal was by mistake and percentage, function test and rate of complication by Ftest(ANOVA) and the rate of complication per items by ${\chi}^2$ and Ftest. As the post test the Duncan's test was used for the statistically significant different variables in the standard of p<.05 after Ftest. The followings are the summary of the result : 1) In the function test of the new hemodialyzer and the reused one, and in all of CA110 and CF15.11, the dialyzer ultrafiltration coeffient(KUf) was appeared to have been higher in the reusing groups than the first use ones. This has been the normal limit showing no troubles with them. 2) In the function test of the new and reused hemodialyzer, in all of CA110 and CF15.11, the total blood volume was appeared to have been the less value in the reuse groups than the new ones. This was the price within 80% of the first price that both showed possible for use. 3) The result of reuse hemodialyzer of CA110 was $29.48{\pm}7.83$ in average in the test of leak test while $17.3{\pm}7.96$ in reuse of CF15.11. The normal limit of <60 was the leak test result. So both of the hemodialyzer was normal for reuse. 4) The rate of removal of Blood Urea Nitrogen(BUN) was 72.25% in CA110 hemodialyzer by reusing 16-20 times as the highest rate showing the better result in the reuse hemodialyzer, while in CF15.11 hemodialyzer showed 71.16% by highest rate in the first use by the highest rate with no difference from the reuse. 5) The rate of removal of serum creatinine of CA110 was 64.08% by highest rate in reuse of 1-5 times by showing better result in reuse hemodialyzer. While in CF15.11 66.47% the highest by reuse of 16-20 times showing no difference from each other. 6) No patients were admitted or precribed by antibiotics in relation with reuse dialyzer and no reports were shown about hepatitis $B{\cdot}C$. AIDS in fection. 7) Of the total 248 episods of complication due to the hemodialyzing, 86 by first use, 73 by 1-5 times, 35 by 6-10 times, 35 by 11-15 times and 19 by 16-20 times have been shown which have had no significant difference between the groups. 8) In the comparison of the expense for the hemodialyzer, there was the effect of saving 11,597.6 Won between the first and reuse hemodialyzer. And by decreasing the extracted materials, they did the great role of disposing the waste matters.

The purpose of the present study was to compare pulsatile type(Twin Pulse Life Support; TPLS) with rotary type hemodialyzer(AK95) in order to reduce the dialysis time and to improve dialysis effect. Three healthy dogs(about 30 kg BW) were used. Experimental renal failure was induced by the ligation of bilateral renal artery. A pair of catheters were implanted in jugular vein for dialysis. Daily investigated parameters included clinical signs such as vomiting, fecal appearance and activity, and also laboratory data such as PCV, TP, BUN and creatinine. Hemodialysis was started above 90 mg/100 ml BUN level and, laboratory data were measured every an hour for 4 hours. Heparin was administered 300 IU/Kg before dialysis and 150 IU/Kg via IV route every 90 minutes during dialysis. Clinical signs after induction renal failure were shown severe vomiting, anorexia, diarrhea, mucous feces, ataxia, dilated pupil and episcleral hyperemia. The average of BUN value decreased hourly $99{\pm}12.1,\;84{\pm}12.2,\;72{\pm}8.0,\;58{\pm}7.1,\;48{\pm}5.2,\;and\;39{\pm}3.2mg/100ml$ by hemodialysis. The average of creatinine value decreased $7.8{\pm}0.61,\;6.4{\pm}0.40,\;5.3{\pm}0.42,\;4.5{\pm}0.23,\;4.0{\pm}0.41,\;and\;3.4{\pm}0.42mg/100ml$ according to hemodialysis an hour. There are not significantly differences BUN, creatinine, PCV and TP values between pulsatile and rotary type hemodialysis. These results suggested that effects of hemodialysis with Pulsatile type(TPLS) are not significantly difference as compared with hemodialysis of rotary type(AK95). Further research is needed in order to estimate the influence of cardiovascular and pulmonary system in hemodialysis of pulsatile type.

It is now well established that transient granulocytopenia is common in patients during the initial phase of hemodialysis with new cuprophane membrane, but not with reused nembrane, or some synthetic membranes. In this study, new cuprophane dialyzer was treated with plasma and albumin, respectively, then, peripheral blood leukocytes were counted at the onset and after 15 minute of hemodialysis. In the plasma-treated group, the percent of leukopenia was less (41.3 %) than control group (71.3 %). In the plasmatreated group, the degree of leukopenia was close to that ot'control grou p. The protective factor, therefore is thought to be present in the plasma other than albumin fraction.

Flow mismatch between blood and dialysate is invariably encountered during conventional hemodialysis, and this deteriorates diffusive mass transfer. A modification of a conventional dialyzer was conceived to prevent this mismatch. The modified dialyzer includes two independent blood flow regions (central and peripheral regions), which were achieved by redesigning the dialyzer cap. Resultantly, the blood stream was divided into two concentric dialyzer regions. Solutes clearances obtained using the modified dialyzers were compared with those of conventional dialyzers. Solutes clearances by conventional dialyzers were uniform, but solutes clearances by modified dialyzers were found to be dependent on the simulated blood split into dialyzer central and peripheral regions. Maximal clearances using the modified dialyzer were improved by up to approximately 7.6% for urea and 7.3% for creatinine, as compared with those of conventional dialyzers. More optimizations are required for clinical applications, but the finding that blood flowrates through central and peripheral fiber bundles can be easily regulated is encouraging.

In this paper, we propose a method of analysing the relation between the patient's face color and his(her) kidney disease using image processing technology. This method is based on the ocular inspection which is one of the most famous diagnosis methods used in the oriental medical system. The way of processing and analysing the face image, which is for visualization and objectification of the color difference, is included. The objects are selected from the patients who suffer the kidney disease and use the hemodialyzer. Their facial images and clinical data are collected. From these data, we propose a hypothesis that the color of the patient's face is changed according to the patient's kidney state. At the same time, we present two algorithms of extracting the specific part of face which can identify the state of the patient's kidney and tracing the history of the color's change. This proposed method is evaluated through the practical experiments and their analysis.
