Polypeptide antigen as isolated from adult worms of Clonorchis sinensis by means of diluted HCl-extraction method. Preliminary intradermal examination with those polypeptide antigen(CPT) were performed on patients of clonorchiasis, paragonimiasis and metagonimiasis and the result of the intradermal test with CPT antigen were compared with those of Clonorchis protein fraction(CPF) and Veronal buffer saline extraction (VBS) antigen. The result of the examination were summerized as follows: When 0.05 ml (1 microgram) of CPT was injected intradermally, the positive intradermal reaction appeared in 42.7 per cent (37 of 82) on the patients of clonorchiasis. The sizes of the wheal and erythema with CPT antigen was smaller than that of CPF and VBS antigen. Intradermal reaction with CPT antigen was carried out for other parasitic diseases, such as paragonimiasis and metagonimiasis. The result indicated that CPT antigen may be showed no cross reactions. Clonorchiasis pateints who with negative reaction to CPT antigen, reacted negatively to CPF and VBS antigens.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii Steindachner , in the downstream of Hyungsan river which is located in Kyungpook province of Korea, were carried out, and the following results were obtained. Metacercariae of Metagonimus species were found in seventy five fishes (40.5 percent) out of 185 examined. Parasitic frequencies of the encysted matacercaria of Metagonimus species in Tribolodon taczanowskii were 23.2 percent (43 out of 185) in the scale, 7.0 percent (13 out of 185) in the gill, and 10.3 percent (19 out of 185) in the flesh. The number of the metacercaria in the scale, gill and flesh were fewer than that of the others. The worms were identified as Metagonimus yokogawai Katsurada, 1912 by morphological studies on the adults and eggs, and compared with prereported Metagonimus species.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained. Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

BACKGROUND: Hemodynamic instability is one of the main concerns for anesthesiologists during orthotopic liver transplantation (OLTX). The most troublesome event would be an increase of central venous pressure associated with sudden right ventricular (RV) filling without any change in heart contractility. An acute increase in RV outflow pressure depresses RV contractility and eventually causes overt RV failure. To avoid such disaster, it would be wise to evaluate right heart pressure/volume relationship and assess contractility when anticipating acute increase of pressure in right heart chamber. METHODS: RV function was assessed in 15 patients undergoing OLTX. RV function was monitored using an ejection fraction catheter and a monitor. Complete hemodynamic profile was obtained on regular intervals. Statistical analysis was performed using ANOVA for repeated measures. Correlation between variables were determined by simple regression analysis and ANCOVA. RESULTS: RV end-diastolic volume was in the range of supranormal values. No correlation was observed between right atrial pressure and RV end-diastolic volume index (RVEDVI). There was a significant correlation between stroke index and RVEDVI. RV ejection fraction and E-single were relatively constant throughout the procedure. There was weak negative correlation between E-signle and RVEDVI. CONCLUSION: RV function appeared to be well preserved during OLTX. However, RV contractility tends to decrease in response to RVEDV increase because RVEDV of endstage liver disease might increase to their maximal value. Right heart filling pressure was less reliable clinical indicator of RV preload.

BACKGROUND/AIMS: It has been reported that the difference in the hepatitis C virus (HCV) genotype due to genetic heterogeneity of HCV influence the clinical features, prognosis of HCV associated liver disease and response to interferon therapy. Prevalence of different genotypes of HCV may also vary between geographic areas. The aim of this study was to examine the relationship between the response to interferon alpha (IFN-a) therapy and HCV genotypes in patients with chronic HCV infection in Taegu and its environs. METHODS: One hundred seventy six patients known to be HCV antibody and HCV-NA positive were evaluated for HCV genotypes by restriction fragment length polymorphism. Among patients who had elevated ALT levels, 67 patients have been investigated for the role of the HCV genotype on disease outcome and the response of IFN-a therapy. RESULTS: Genotype 1b were found in 59.0% of patients (103/176), genotype 2a in 37.5% (66/176). The mode of transmission of HCV infection was guessed as transfusion in genotype 1b, but as parenteral infection in genotype 2a. According to their response to IFN-a therapy, 73 patients were divided into three groups, complete response, 18 (60%) of 30 patients with genotype 2a and 21 (48.8%) of 43 patients with genotype 1b: partial response, 5 (16.7%) of 30 patients with genotype 2a and 7 (16.2%) of 43 patients with genotype 1b: no response, 7 (23.3%) of 30 patients with genotype 2a and 15 (34.9%) of 43 patients with genotype 1b. Good response to IFN-a therapy was observed among patients group showing normal platelet count in patients with genotype 1b and normal GGT in patients with genotype 2a. CONCLUSIONS: The most frequently identified genotype was genotype 1b in Taegu and its environs, followed by genotype 2a. The HCV genotype was not a reliable predictor of response to IFN-a therapy. When a standardized regimen of IFN-a was administered, pretreatment serum platelet counts and GGT level seem to be useful predictor of IFN-a therapy in HCV infection. Further investigations are required in order to establish a correlation between viral factors and therapeutic responses.

Korean Journal of Anesthesiology 2001;40(3):340-347
BACKGROUND: Pulmonary hypertension (PH) associated with end stage liver disease is rare but the risk of hemodynamic deterioration during liver transplantation may be high. This study was done to characterize the pulmonary hemodynamics during liver transplantation and to seek the relationship between pulmonary artery pressure (PAP) and other hemodynamic variables. METHODS: One hundred patients undergoing liver transplantation were chosen and we divided patients into normal and PH groups (mean pulmonary artery pressure [MPAP] > 25 mmHg). Hemodynamic data was collected throughout the surgery. Studied variables between groups were analyzed with an unpaired t-test. The relationship between MPAP and other hemodynamic variables was analyzed with a linear regression test. Survival analysis was performed by cumulative survival analysis (Logrank test). RESULTS: Incidence of PH during liver transplantation was 34%, and true PH (pulmonary vascular resistance index [PVRI] > 150 dyne.sec/cm5/m2, MPAP > 25 mmHg) was 7%. MPAP, systemic vascular resistance index, cardiac index, right ventricular ejection fraction, maximum elastance, central venous pressure (CVP), pulmonary artery occlusion pressure (PAOP), and right ventricular end-diastolic volume index were significantly higher in the PH group. In the PH group, right ventricular function curve was abnormal. MPAP correlated significantly with PAOP, and CVP (P < 0.01). One year survival rate showed no significant difference between groups (Logrank test P = 0.49). CONCLUSIONS: Episodes of increased pulmonary artery pressure during liver transplantation was not infrequent. PAP was more dependent on preloads. In patients with high PAP, RV diastolic dysfunction was usually observed. Early mortality rate after liver transplantation was not associated with PH.
