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.

The congenital diverticulum of ventricle is a rare cardiac malformation arising from the left or right ventricle, the former being more common. Ventricular diverticulum is usually associated with other anomalies including intracardiac, midline thoracic, diaphragmatic and abdominal wall defect. The authors experienced a case of congenital diverticulum of left ventricle in nine month-old female infant. Left Blolock-Taussig shunt operation was done and total correction will be done later. Thereafter we presented a case with brief review of the related literatures.

The aseptic loosening has emerged as one of the most common and serious long term complications, which requires the revision of total hip replacement arthroplasty. We studied the radiologic finding of the aseptic loosening in 79 patients of uncemented total hip replacement arthroplasty which had been performed in our hospital from March 1991 to December 1994. We evaluated the white reaction lines, osteolysis state, translation and migration in postoperative and last follow-up radiographies. The white reactive lines around the femoral stem and the acetabular cup were most frequent in zone IV and zone II. But it was not progressive and need more long term follow-up evaluations to confirm whether these lines are related to loosening or not. In assessment for stable state, the more stable at initial fixations, the better state of long term stability. Some patients have pain without loosening but all patients with loosening have pain. Press fit is the most important factor of the late stability. The osteolysis is not directly proportional to femoral loosening in this study, but it might be due to short follow up time.

The incidence of herniated lumbar disc under the age of 19 years is increasing due to increased sports activity of teenager and development of diagnostic methods. 33 cases of herniated lumbar disc of the teenager was analyzed at Department of Orthopaedic Surgery, Dong-A College of Medicine from March 1990 to May 1994. The results were obtained as follows: 1) Among 413 patients, 33 patients(7.9%) were teenagers and the sex ratio was 2.3:1 in male to female. 2) Average intervals between the onset of clinical symptoms and the admission were 13.2 months. 3) 20 cases(60.6%) had a definite trauma history, and among these cases, 14 cases(70.0%) were associated with sports activity. 4) The most common level of herniation was L4-5 in 29 cases(64.4%), straight leg raising test was positive in 32 cases(97.0%), sensory change in 13 cases(39.4%), motor weakness in 10 cases(30.3%). 5) Among positive MRI findings(32 cases), 17 cases(53.1%) were the protruded type. 6) Among 23 operative cases, 21 cases had excellent or good results.

Among the 413 patients of the lumbar herniated nucleus pulposus(HNP) who were admitted and treated at Dong-A University Hospital from March 1990 to May 1994, we analyzed 387 patients who checked magnetic resonance imaging(MRI). MRI study followed by open disectomy was carried out on 127 patients of the lumbar HNP, and we analyzed the clinical and operative findings of the lumbar HNP and compared these with MRI findings. The following results were obtained. 1. MRI findings of 387 patients consisted of bulging discs in 107 cases(27.6%), protruded discs in 165 cases(42.6%), extruded subligamentous discs in 73 cases(18.9%), extruded transligamentous discs in 34 cases(8.8%) and sequestered discs in 8 cases(2.1%). 2. MRI findings of 127 patients who had been treated with open discectomy consisted of protruded discs in 53 cases(41.7%), extruded subligamentous discs in 47 cases(37.0%), extruded transligamentous discs in 19 cases(15.0%) and sequestered discs in 8 cases(6.3%). 3. Operative findings revealed the protruded discs: 49 cases(38.6%), extruded subligamentous discs: 52 cases(40.9%), extruded transligamentous discs: 18 cases(14.2%) and sequestered discs: 8 cases(6.3%). 4. In sequestered disc, we could get the highest sensitivity, specificity and accuracy with MRI in distinguishing from another type of lumbar HNP. MRI can be available for accurate assessment of type and location of the lumbar HNP and it can show the high specificity, sensitivity and accuracy in preoperative diagnostic method.

PURPOSE: Various vasopressor agents are used to raise systemic vascular resistance (SVR) during liver transplantation. After grafted liver was reperfused, postreperfusion syndrome could be treated with various vasopressors. However, epinephrine can decrease the splanchnic perfusion and oxygen saturation and then hepatic blood flow would be jeopardized. Decreased hepatic blood flow might result in centrilobular necrosis which contributes to disruption of liver functions. We tried to know the effect of epinephrine on tissue perfusion of the liver. METHODS: In this study, measurement of hepatic microcirculation (HMC) and hemodynamic changes was performed in eight dogs to investigate the effect of vasopressors on hepatic microcirculation. Animals were divided into four groups in which low-dose epinephrine (0.05mug/Kg/min) and high-dose epinephrine (0.5mug/Kg/min) were randomly infused into the systemic vein and portal vein (1/6 of systemic dose) for ten minutes. Hepatic microcirculation was measured by Thermal Diffusion Probe. RESULTS: At low-dose systemic infusion of epinephrine, mean arterial bloodpressure (MABP), cardiac output (CO), and hepatic microcirculation (HMC) were significantly increased but systemic vascular resistance (SVR) was decreased. On high-dose epinephrine, MABP, CO (P=0.01), and SVR were significantly increased without changes of HMC. Intraportal infusion of low- and high-dose epinephrine increased hepatic vein pressure and SVR, respectively. CONCLUSION: These results would provide clues that systemic low-dose epinephrine infusion is enough to raise HMC and high-dose infusion of epinephrine to raise SVR could be used without jeopardizing HMC.
