Cortex mori (Morus alba L.), the root bark of mulberry tree, has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. The purpose of this study was to determine whether Cortex mori could inhibit the ovalbumin (OA) -induced late asthmatic reaction in guinea pigs. Guinea pigs were sensitized by two exposures to an aerosol of OA(1.0%) and then challenged with aerosolized antigen(2.0%), The animals were pretreated by three inhalations of the aerosoled Cortex mori either before antigen sensitization or cahllenge. Bronchoalveolar lavage fluid(BALF) and peripheral blood were collected at 17 hours after OA challenge. The cell populations in BALF and peripheral blood were examined to determine the changes of the relative proportions of eosinophils,neutrophils and mononuclear cells etc. Beta-glucuronidase activity in BALF was measured to evaluate the alveolar macrophage activation. OA-induced histamine release from guinea pig peritoneal fluid cells was measured by radioisotope enzymatic asssay. Results were as follows. The number of eosinophils, neutriphils and lymphocytes recovered in BALF were significantly increased in the 17h following aerosol challenge with OA. Among them, eosinophil and neutriphils were decreased remarkably in group that had been preinhalated with Cortex mori. The number of lymphocytes in BALF were not decreased in group pretreated with CM before sensitization but decreased in Group pretreated with CM before challenge. After OA challenge, the number of eosinophils in peripheral blood were markedly increased, but Cortex mori inhibited significantly the OA-induced eosinophilia. Beta-glucuronidase activity in the supernatants of BALF were significantly increased in the 17h following aerosol challenge with OA, however, pretreatment of Cortex mori had no influence on Beta-glucuronidase activity, suggesting that Cortex mori had no inhibitory effect on OA-induced alveolar macrophage activation. Cortex mori inhibited the OA-induced histamine release from guinea pig peritoneal fluid cells. From the above results, it is suggested that Cortex mori contains some substances with an activity to inhibit the the OA-induced late phase reaction of the bronchial asthma in guinea pigs.

The biochemical characteristics of immunorecative atrial natriuretic peptide (irAUPP and the changes in the levels of irANP in the heart were investigated during the metamorphosis of frog tadpoles. Immunohistochemical localization of pro-ANP in cardiocfes and the presence of irAW in the peritoneal fluid of metamorphosing tadpoles were also examined. The major form of irANP in the cardiocvtes of tadpoles (Rana omurensisp was high molecular weight on gel filtration chromatographv and reverse-phase HPLC. The levels of irANP in the atrium of tadpoles were five to seven times higher than those in the ventricle. In metamorphosing tadpoles the levels of irANP in the atrium increased at stage XX, the climax of metamorphosis, and decreased at stage XXV (P < 0.051, the completion of metamorphosis. When the levels of irANP was expressed as a function of body weight of tadpoles, a continuous increase in the levels of irANP was observed from pre- to postmetamorphosis (P < 0.051. The levels of irAUP in the ventricle were found to be higher in the adult frogs than in tadpoles (R. omurensisl (P < 0.01). Pro-ANP (31-67) immunoreactivity was detected in the ventricle as well as in the atrium of tadpoles fR. nigromaculotal. The peritoneal fluid was also found to contain low molecular weight of irAUP and the levmils of irANP were 55.4 $\pm$ 9.1 pg/ml. Changes of the level of irANP at different stases of the life cycle suggest that ANP may play a role in the regulation of body fluid homeostasis of frog tadpoles during the metamorphosis.

A 5-years-old female pointer dog was submittedto the hospital with the disease history of gradual distension of abdomen and emaciation for two months. An applesized hard mass was palpated on the right costal arch on physical examination. On blood chemical analysis, the marked elevation of SALT and decrease in serum albumin were detected. On paracentesis, a large volume of blood tinged fluid was detected. The peritoneal fluid contained tumor cells and the numerous blood cells. At autopsy the tumor mass located in the left medial lobe of liver was whitish and firm, and was consisted of many cysts. Histologically the tumor was identified as typical cholangiocellular carcinoma. Metastatic lesions of the tumor were detected in the lung, stomach, spleen, diaphragm, and lymph glands. This observation indicates that the cytological examination of the abdominal fluid have a diagnostic significance in the clinical examination of patients with abdominal tumors.

Purpose: This study was performed to investigate the effects of Keukhachukeo-Tang (KCT) on the development of experimentally-induced endometriosis in rats. Methods : Endometriosis was induced in rats by autotransplanting uterine tissue to the peritoneum and devided them into three groups: (1) sham-operated group (n=8), (2) surgically induced endometriosis and untreated control group (n =8), (3) surgically induced endometriosis and KCT treated group. KCT (1,200 mg/head) was orally administrated for 15 days after operation. Then we measured the body weight, the volumes of endometriotic implants. The weight (body, left uterus and ovaries) and concentrations of cytokines (MCP-1, TNF-${\alpha}$, IL-l${\beta}$) in serum and peritoneal fluid were also measured. Histopathology, immunohistochemistry for COX-2, and histochemistry for mast cells in transplanted uterine tissue were performed. Results : - The volumes(mm$^3$) of endometriotic implants in KCT-treated group (107${\pm}$66) were significantly decreased (p<0.05) compared with control group (405${\pm}$318). - The contents(pg/ml) of MCP-1 in peritoneal fluid in KCT-treated group (6,940${\pm}$893) were significantly decreased (p<0.01) compared with control group (8,632${\pm}$1,245). - The contents(pg/ml) of TNF-${\alpha}$ in peritoneal fluid in KCT-treated group (847${\pm}$330) were significantly decreased (p<0.05) compared with control group (1,245${\pm}$362). - The percentages(%) of positive epithelial layers for COX-2 in KCT-treated group (31${\pm}$10) were significantly decreased (p<0.01) compared with control group (50${\pm}$8). - The numbers of mast cells in adjacent tissue of transplanted uterine tissue in KCT-treated group (69${\pm}$18) were significantly decreased (p<0.01) compared with control group (109${\pm}$30). - The numbers of mast cells in stroma of transplanted uterine tissue in KCT-treated group(16${\pm}$5) were significantly decreased (p<0.01) compared with control group (26${\pm}$8). - Histopathologically, proliferation of endometriotic epithelia and stroma, and infiltration of inflammatory cells in transplanted uterine tissue of KCT-treated group were weakly observed than those of control group. Conclusion : From the above results, Keukhachukeo-Tang (KCT) have inhibiting effects on the development of transplanted uterine tissue. And these effects are related to the decreased concentration of MCP-1 and TNF-${\alpha}$, decreased expression of COX-2, and decreased infiltration of mast cells by administration of Keukhachukeo-Tang.

The purposes of this study were to evaluate the effects of insulin-like growth factor (IGF)s in peritoneal fluid (PF) from patients with and without endometriosis on the proliferation of endometrial stromal cells and to investigate the effects of type I IGF receptor antibody on the response of endometrial stromal cells to PF from patients with endometriosis. IGFs in PF from patients with endometriosis (n=14) and without endometriosis (n=10) were measured by immunoradiometric assay and PF samples were divided into low IGF-I PF group (less than 85 ng/ml) and high IGF-I PF group (more than 85 ng/ml). Endometrial stromal cells from patients without endometriosis were cultured in serum free media in the presence or absence of 1 % PF and thymidine incorporation test were used to evaluate the proliferation of endometrial stromal cells. Also cultures were incubated with type I IGF receptor monoclonal antibody (${\alpha}IR_3$) before adding PF. PF from patients with endometriosis and without endometriosis increased thymidine incorporation in endometrial stromal cells. In patients with endometriosis, high IGF-I PF group had high IGF-II levels and resulted in higher thymidine incorporation than low IGF-I PF group but no significant difference in increase in thymidine incorporation between high IGF-I and low IGF-I PF group was noted in patients without endometriosis. There was not a significant correlation between increase in thymidine incorporation and IGF-I levels in PF from patients without endometriosis but in PF from patients with endometriosis. Preincubation with ${\alpha}IR_3$ significantly inhibited the mitogenic response of endometrial stromal cells to PF. Our data indicate that IGF-I in PF may be involved in the growth of ectopic endometrium in patients with endometriosis.

Recently, the survival rates of extremely low-birth-weight (ELBW) infants have improved with the development of neonatal intensive care. However, these infants were susceptible to intestinal perforation due to prematurity, fluid restriction, and injection of indomethacin, etc. Because of the risks of transportation, anesthesia and surgery itself, peritoneal drainage has been compared with laparotomy. Through our experience, we investigate the usefulness of peritoneal drainage retrospectively. From 1997 to 2007, six ELBW (M:F=5:1) underwent primary peritoneal drainage for intestinal perforation. Their median birth weight was 685g (405~870) and gestational age was $25^{+1}$ weeks ($24^{+3}{\sim}27^{+0}$). We noticed the intestinal perforation at median 10.5 days (8~18) after birth, and placed Penrose drain or Jackson-Pratt drain through right lower quadrant incision under local anesthesia. The cause of intestinal perforation was necrotizing enterocolitis in one patient, but that of the others was not clear. Three patients who showed normal platelet count and stable vital signs recovered uneventfully. Two patients (birth weight less than 500g) who showed unstable vital signs and low platelet count (12,000 / $mm^3$ to 30,000 / $mm^3$)expired despite aggressive resuscitation. One patient required laparotomy due to persistent intestinal obstruction after drain removal and survived. Our experience shows that peritoneal drainage was an acceptable treatment for ELBW infants and the prognosis was related to vital sign and platelet count at the time of intestinal perforation, and birth weight.

배 경 : 패혈증에서 과도한 활성산소종의 생성은 급성 폐손상의 병리 기전에 중요한 역할을 한다. Catalase 및 MnSOD 등의 항산화 단백은 패혈증 환자의 혈청내 증가하며 급성호흡곤란증후군의 발생 예측 인자 및 패혈증의 예후 인자로 알려져 있다. Peroxiredoxin(Prx) 는 최근 독특하고 중요한 세포내 항산화 단백으로 알려져 있다. 본 연구는 대식세포인 mouse monocyte-macrophages(RAW 264.7) 세포에 산화 스트레스 및 내독소 처리후 Prx I 및 Prx II의 발현 평가하고 패혈증 동물 모델에서 복강세척액 및 기관지폐포세척액내 Prx I, Prx II 및 Trx의 양을 측정하였다. 방 법 : Prx I, Prx II 및 Trx에 대한 특이 항체를 이용하여 immunoblot 분석으로 호중구, 대식세포 및 적혈구에 이들의 분포를 평가하였다. Mouse monocyte-macrophages 세포에 $5\;{\mu}M$ menadione 및 1 mg/ml lipopolysaccharide(LPS) 을 처치하여 Prx I 및 Prx II의 발현을 평가하였으며 6 mg/Kg LPS를 복강내 투여하여 유발한 복강내 패혈증 동물의 복강세척액내 Prx I, Prx II 및 Trx의 양을 측정하였으며 복강내 패혈증 동물 및 5 mg/Kg LPS를 정맥내 투여하여 유발한 정맥내 패혈증 동물에서 기관지폐포세척액내 Prx I, Prx II 및 Trx을 측정하였으며 폐장의 염증 정도와 비교하였다. 결 과 : Prx I 및 Prx II의 분포는 호중구, 폐포대식세포 및 적혈구에서 서로 다른 양상을 보였다. Mouse monocyte-macrophages 세포에 $5\;{\mu}M$ menadione 및 $1\;{\mu}g/ml$ lipopolysaccharide을 처치하였을 때 Prx I 발현은 증가하였으나 Prx II 발현은 변화하지 않았다. 복강내 패혈증 동물에서 복강세척액내 Prx I, Prx II 및 Trx의 양은 증가하였으나 복강내 패혈증 및 정맥내 패혈증 동물에서 기관지폐포세척액내 폐장 염증 정도와 관계없이 Prx I, Prx II 및 Trx의 양은 증가하지 않았다. 결 론 : 세포내 항산화 단백으로서 mouse monocyte-macrophages 세포에서 Prx I의 발현은 산화 스트레스 및 내독소 처치후 증가한다. Prx I, Prx II 및 Trx양은 패혈증 동물 모델에서 국소 염증 부위에서 증가하나 손상된 폐장에서는 증가하지 않는다.

Leptomeningeal metastasis is a devastating complication of advanced stage cancer. It is frequently accompanied by hydrocephalus and intracranial hypertension that must be treated by ventriculoperitoneal shunts. However, there are actual risks of peritoneal seeding or accumulation of malignant ascites after the cerebrospinal fluid diversion procedure, though it has not been reported. Here, we present the case of a patient with non-small cell lung cancer with leptomeningeal metastasis in whom malignant ascites developed after a subduroperitoneal shunt.

Although the ventriculo-peritoneal shunt is the treatment of choice when hydrocephalus should be corrected, the ventriculo-atrial shunt still holds strong alternative when the peritonium is precluded due to the several reasons. During the ventriculo-atrial shunt operation, it is not always easy to dissect and find the corresponding venous structures. In this technical note, the author describes a simple method of percutaneous insertion for placement of the atrial end.
