To examine effects of oriental pharmaceutical preparations on immunity, four of such preparations which are currently being used were examined. After their fluid extracts were injected intraperitoneally to ICR mice, the counts of total cell number, PMN and macrophage in the peritoneal cavity were made by using non-specific esterase staining method, and plaque-forming cells (PFC) were measured by using the modified method of Cunningham and Jerne. The results showed that 'Bo-Jung-Ik-Ki-Tang', 'Ih-Jung-Tang', 'Ohn-Kyeong-Tang' and 'Ke-Ji-Bok-Ryeong-Hwan-Ka-Dae-Hwang' increased both the macrophages and the total cells of the peritoneal cavity and that these preparations increased the number of PFC in the spleen. Therefore the data indicate that they potentiate both of the cell­mediated and humoral immunities in the mice.

To investigate and evaluate the scavenging and antioxidative effects of various ftavonoids on paraquat induced pulmonary toxicity, in vivo and vitro tests of eight flavonoids(catechin, epicatechin, flayone, chrysin, apigenin, quercetin, morin and biochanin A) were carried out. In vitro test, inhibitory and antioxidative effects of lipoxygenase dependent lipidperoxidation, NADPH dependent cytochrome p-450 reductase to liver and lung microsome and superoxide anion production in rat peritoneal exudated macrophage were studied. In vivo test, biochemical parameters and cell population in bronchoalveolar lavage fluid(BALF) in mouse and rats after administration of paraquat and flavonoids were tested. The results are summerized as follows; 1. All flavonoids tested inhibited on NADPH dependent cytochrome p-450 reductase in liver and lung microsome. 2. All flavonoids tested showed the inhibitory effects on the superoxide anion production in rat peritoneal exudated macropharge. 3. Lactate dehydrogenase, acid phosphatase and total protein in BALF of mouse which increased by the administration of paraquat, decreased significantly by catechin, chrysin, morin and biochanin A. 4. Numbers of alveolar macropharge and PMN in BALF of rats which increased by the administration of paraquat decreased by all the tested flavonoids. Therefore, all flavonoids tested showed the useful compounds for scavenger and antioxidant on paraquat induced pulmonary toxicity.

Background: B cell subset has been divided into B-1 cells and B-2 cells. B-1 cells are found most prominently in the peritoneal cavity, as well as constituting a small pro portion of splenic B cells and they are larger and less dense than B-2 cells in morphology. This study was designed to compare the differences in their proliferation and differentiation between B-1 and B-2 cell. Methods: We obtained sorted B-1 cells from peritoneal fluid and B-2 cells from spleens of mice. Secreted IgM was measured by enzyme-linked immunosorbent assay. Entering of S phase in response to LPS-stimuli was measured by proliferative assay. Cell cycle analysis by propidium iodide was performed. p21 expression was assessed by real time PCR. Results: Cell proliferation and cell cycle progression in B-1 and B-2 cells, which did not occur in the absence of LPS, required LPS stimulation. After LPS stimulation, B-1 and B-2 cells were shifted to Sand G2/M phases. p21 expression by resting B-1 cells was higher than that of resting B-2 cells. Conclusion: B-1 cells differ from conventional B-2 cells in proliferation, differentiation and cell cycle.

Echinococcosis is a multisystem disease and has propensity to involve any organ, an unusual anatomical site, and can mimic any disease process. Primary peritoneal echinococcosis is known to occur secondary to hepatic involvement but occasional cases of primary peritoneal hydatid disease including pelvic involvement have also been reported. We report here 1 such case of primary pelvic hydatidosis mimicking a malignant multicystic ovarian tumor where there was no evidence of involvement of the liver or spleen. Our patient, a 27-year-old female, was detected to have a large right cystic adnexal mass on per vaginal examination which was confirmed by ultrasonography. Her biochemical parameters were normal and CA-125 levels, though mildly raised, were below the cut off point. She underwent surgery and on exploratory laparotomy, another cystic mass was found attached to the mesentery of the small gut. The resected cysts were processed histopathologically. On cut sections both large cysts revealed numerous daughter cysts. Microscopic examination of fluid from the cysts revealed free scolices with hooklets and the cyst wall had a typical laminated membrane with inner germinal layer containing degenerated protoplasmic mass. The diagnosis of pelvic hydatid disease was confirmed and patient was managed accordingly. Hydatid disease must be considered while making the differential diagnosis of pelvic cystic masses, especially in endemic areas.

CpG-DNA triggers the proliferation and differentiation of B cells which results in the increased production of antibodies. The presence of bacteria-reactive IgM in normal serum was reported; however, the relevance of CpG-DNA with the production of bacteria-reactive IgM has not been investigated. Here, we proved the function of CpG-DNA for the production of bacteria-reactive IgM. CpG-DNA administration led to increased production of bacteria-reactive IgM both in the peritoneal fluid and serum through TLR9 signaling pathway. When we stimulated B cells with CpG-DNA, production of bacteria-reactive IgM was reproduced in vitro. We established a bacteria-reactive monoclonal IgM antibody using CpG-DNA stimulated-peritoneal B cells. The monoclonal IgM antibody enhanced the phagocytic activity of RAW 264.7 cells against S. aureus MW2 infection. Therefore, we suggest that CpG-DNA enhances the antibacterial activity of the immune system by triggering the production of bacteria-reactive IgM. We also suggest the possible application of the antibodies for the treatment of antibiotics-resistant bacterial infections.

Objective: To evaluate the technical feasibility and the clinical effectiveness of sclerotherapy for the treatment of peritoneal inclusion cysts (PICs). Materials and Methods: Between June 1996 and February 2001, eight PICs in seven female patients aged 28-43 (mean, 36) years were instilled with sclerosant (povidone-iodine in three, ethanol in three, both povidone-iodine and ethanol in one). All seven patients subsequently experienced less abdominal pain. After drainage via an 8.5-Fr pigtail catheter inserted in the PICs (transabdominally in six cases, transvaginally in one), sclerosant equivalent in volume to about one-third that of drained fluid was introduced daily until the drained volume was less than 5ml. Follow-up by means of clinical procedures and ultrasound was performed every three months, at which time the success rate, possible complications and recurrence were determined. Results: Sclerotherapy was technically successful in all seven patients, though immediately after the procedure, minor complications were noted in three patients (mild pain in two, mild fever in one). During the follow-up of 4-60 (mean, 24.7) months, sclerotherapy proved successful and without long-term complications in all seven patients: lower abdominal pain disappeared and the diameter of the cysts decreased more than 50%, with complete regression in four cases. During the follow-up period there was no recurrence. Conclusion: Sclerotherapy following catheter insertion is technically feasible and effective for the treatment of PICs.

The leading cause of death in patients with chronic renal failure is cardiovascular diseases. The problems relevant to cardiac surgery in these patients are occurring more frequently with a growing number of patients at risk. Among these, important risk factors related to uremic patients undergone open heart surgery are fluid and electrolytes imbalance, coagulopathy, increased susceptibility to infection. Since 1968 when Lansing and colleagues reported the first successful aortic valve replacement in patients with chronic renal failure and infective endocarditis, there have been increasing reports of the cardiopulmonary bypass surgery in chronic renal failure patients with acceptable perioperative morbidity and mortality From Jan. 1988 to Nov. 1989 we have experienced four uremic patients necessitating open heart surgery ; one needing a coronary artery bypass graft and the other 3 needed cardiac valve replacement. Based on our observations we would like to suggest followings 1]Intraoperative ultrahemofiltration during C-P bypass thought to be an excellent means for the control of hyperkalemia and fluid balance. 2] The immediate postoperative application of peritoneal dialysis instead of hemodialysis is beneficial in controlling fluid and electrolyte imbalance. 3]The cause of one early postoperative death was not associated to renal failure, rather it was the result of an accidental rupture in the right ventricular wall.

A 4-year old Korean-native cow of third parturition delivered an deformed calf with congenital anasarca and hypoplasia of the extremity at Muan County in Chonnam Province. At parturition, the dam showed amniotic fluid approximately two times more than that at the normal and also occurred severe dystocia. The anomaly died before parturition was 82 cm long and weighed 25 kg. It was difficult to recognize the neck and face of the anomaly due to severe edema and the stretched tongue through mouth was found. The shape of the extremity was recognizable and the systemic hypoplasia of the body with marked edema was found. At necropsy, there was a large amount of serous fluid both in pleural and peritoneal cavity. Also the fluid was contained some of yellowish granular materials and diffusely was fulfilled in all subcutaneous tissue. There was a partial opening in diaphragm which was resulted in the protrusion of approximately half of liver toward peritoneal cavity. There were two kidneys (15${\times}$21 and 13${\times}$18 cm) on the left which were enlarged and relatively larger than the right one (13${\times}$9 cm). In addition, there were found slight to moderate hepatomegaly and splenomegaly with slight congestion, and diffuse edema of intestinal serosa. Lung (32${\times}$49 mm) with marked hypoplasia was smaller than the size of heart (56${\times}$45mm). Serological test to the dam showed relatively high antibody titer (＞64) to Akabane virus which might be involved in the outbreak of the deformed Korean-native calf as one of many causative agents.

We report the experiences of pump-driven continuous venovenous hemofiltration therapy in three children with acute renal failure. The all three patients required mechanical ventilation and needed the support of vasopressors. Renal replacement therapy was needed to meet the metabolic and fluid balance, but intermittent hemodialysis and peritoneal dialysis were not feasible because of hemodynamic instability and concurrent infection. We instituted pump-driven continuous venovenous hemofiltratlon (CVVH), and immediate improvement of pulmonary edema and successful removal of retained fluid were observed. Urea clearance also was satisfactory. During the filter running time, significant thromboembolic event or rapid drop of systemic blood pressure were absent. We concluded that the CVVH is an effective and safe method of renal support for critically ill pediatric patient.

This study was undertaken to evaluate the effect of rabbit peritioneal fluid(rPF) on in vitro maturtion of porcine follicular oocytes. From does 20h after hCG injection, rPF was aspirated aseptically at laparatomy, and then centrifuged, filtrated, and preincubated immediately for 12h. Porcine follicular oocytes isolated from ovaries of slaughtered animals were incubated in TCM-HEPES＋10% FCS, TCM-HEPES＋rPF(v/v, 50/50), or rPE only and examined the nuclear maturation after aceto-orcein or hochest staining. After identifying the optimal incubation time, this experiment was repeated for 5 times. Under the TCM-HEPES containing hormones and serum codition, the time range of porcine follicular oocyte maturation was 38 to 44 hours and the optimal time of maturation of follicular oocyte in vitro was 42 hour cultivation, respectively. The maturatin rates(89.4% and 92.7%) of porcine follicular oocytes cultured in the media with 50% rPF or only rPF were signifciantly higher thanthat (84.6%) of oocytes cultured with TCM-HEPES, respectively. These results suggest that the unknown components(s) of rPF promoted in vitro maturation of porcine follicular oocytes.
