To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.

BACKGROUND: Korean mistletoe (Viscum album) extract has been found to posses immunostimulatory activity. In this study, Korean mistletoe extract, M11C (non-lectin components), was used to know whether this extract might activate mouse peritoneal macrophages to produce interleukin 1 beta (IL-1 beta). METHODS: Hemagglutination assay was carried out to examine whether M11C contained a lectin or not . To know the effect of M11C on the production of IL-1 beta, the macrophages were treated by the M11C, and then collected the supernatant (M11C stimulated macrophages-conditioned media; MMCM). MMCM was analyzed for the IL-1 beta quantification and mRNA expression by means of ELISA and RT-PCR, respectively. RESULTS: Maximum effective dose and time of M11C on IL-1 beta production from macrophages were 20 micro gram/ml and 8 hours, respectively . This ELISA data was reconfirmed by immunoblotting assay . indicating that M11C is a good candidate for an immunomodulator. The dose and time dependent effect s of M11C on the expression of IL-1 beta mRNA from macrophages was also shown in expression of mRNA detected by RT-PCR. Treatment dose and time for the maximum expression of IL-1 beta mRNA were 20 micro gram/ml and 4 hours, respectively . Maximum gene expression of IL-1 beta was much earlier than maximum production of it. CONCLUSION: As results, Korean mistletoe extract, M11C, may be used for an immunomodulator. This will be able to make up for and solve the problems caused by existent immunoagent with many adverse effects through many other studies in future including one molecule extraction.

Arteriovenous fistulae(AVF) are well documented complications of percutaneous renal biopsy. Between August 1995 and April 1997, we prospectively studied 280 consecutive ultransound-guided percutaneous renal biopsies to evaluate the incidence of post-biopsy AVF and its natural course. All biopsies patients were monitored through a routine follow-up echo-color popple sonography at post-biopsy 1, 7, 14 and 30 days. The 28 patients(10%) out of 280 consecutive percutaneous renal biopses were diagnosed to have AVF. There was no differences in the incidence of AVF between native and transplanted kidney biopsy. Most AVF were small(<2cm) and caused minimal or no symptoms. AVF was accompanied with large hematoma(thickness above 2cm) was observed in 9 cases(53%) of 17 native kidneys and none in 10 transplanted kidneys. This difference was statistically significant(P=0.008). At follow-up, AVF resolved spontaneously in 24 cases(87%). In two patients(7.1%) required superselective arterial embolization, one develoved spontaneous rupture of AVF, and one had persistence of AVF over 12 months. We concluded that color Doppler sonography provides a good, non-invasive and safe method for diagnosis and follow up of post-biopsy AVF.

A prospective randomised trial was performed to assess the diagnostic accuracy according to the time interval and the efficacy of endoscopic injection of hypertonic saline-epinephrine(HS- E)solution, consisting of 3.5% sodium chloride with 0.0045% epinephrine, for actively bleeding peptic ulcers, exposed vessel or blood clot on ulcer bed, or Mallory-Weiss tear. Over 24 month, emergency endoscopy in 180 patients admitted for upper gastrointestinal hemorrhage identified 51 patients with nonvariceal hemorrhage. The causes of bleeding were; gastric ulcer in 32; duodenal ulcer in 13; gastric cancer in 4; Mallory-Weiss tear in 2. With this method, the hemostatic effect was permanent in 40 cases(84.3%), temporary in 9 cases(11.8%), and failed in 2 cases(3.9%). By applying this method, the rate of emergency operation for patients with bleeding from the upper gastrointestinal tract was significantly reduced from 20.0% (8/40)to 3.9%(2/51)(p<0.05). Emergency endoscopy in acute UGI bleeding increases the accuracy of detection of actual bleeding sites(p<0.05), but if the endoscopic procedure was performed within 48 hours, the hemostatic rate was not affected(p<0.05). We concluded that hypertonic saline-epinephrine injection method could provide a simple maneuver with reasonable cost, high safety, and satisfactory hemostatic efficacy in the treatment of nonvariceal upper gastrointestinal bleeding.

Currently, endoscopic injection sclerotherapy(EIS) is the most widely used method for treating and eradicating acutely bleeding esophageal varices in repeated sessions, but may be associated with some undesirable local and systemic complications. (continue...)

Postburn sternomental contractures (PBSMC) of the neck can cause difficulties in endotracheal intubation when the cervical hyperextension and lifting of the mandible are impaired. Ten patients with a healed burn of the neck were assessed prior to surgery using the modified Mallampati test, and by measuring the sternomental distance, interincisor gap with their mouth fully open, and using Onah's classification system for PBSMC. Difficult endotracheal intubation was predicted. The patients were intubated successfully with a fiberoptic bronchoscope. The fiberoptic bronchoscope was found to be a useful device for managing patients with PBSMC. Moreover, Onah's classification system can be used for assessing postburn contractures.

Nowadays in the field of plastic surgery, operations with no general anesthesia have been much increased, using daily surgery center. We used "Propofol TCI system" to control exact target concentration of conscious sedation and to reduce any systemic complication of the other local anesthetics. Twenty of ASA Class I or II patients were scheduled for elective surgery using Diprifusor(R) TCI system at 0.8-1.9 ug/ml target concentration. We estimated the proper target concentration, time of awakening, postoperative patient satisfaction and presence of postoperative amnesia. All the patients was satisfied except one patients who underwent nasal tip plasty. The target concentration of the conscious sedation varies with age and the type of operation but average concentration was 1.4-1.6 ug/ml. The average time of awakening, which we estimated by the time of eye opening was 2.6 minutes. Postoperative systemic complication and unusual vital sign were not present. We present here our satisfactory results using propofol infused by TCI(Target controlled infusion) system. This system is called 'Diprifusor(R)' and has a benefit of excellent sedative effect, low complication rate, safety, and rapid awakening time which enables the patient to return to his normal life cycle.
