The pulmonary arterial pressure(PAP) was reported to be higher in essential hypertensives than in normotensives, but the underlying mechanisms for the higher PAP were not known exactly. In order to observe the changes of pulmonary hemodynamics and to get an insight into the mechanism of the pulmonary hypertension, if any, in essential hypertensive patients, the autors performed the cardiac catheterization in 13 normal controls(group A), 14 coronary patients with normal systolic left ventricular function and systemic blood pressure(group B), and 15 essential hypertensives with normal coronary artery and systolic left ventricular function(group C). 1)Pulmonary arterial pressure(PAP) was 19.2+/-3.2/8.1+/-1.9/12.0+/-1.9(s/d/m)mmHg in group A, 25.0+/-6.2/12.8+/-4.0/16.3+/-4.5mmHg in group B, 29.3+/-6.1/12.8+/-4.0/18.2+/-3.6mmHg in group C. The PAP was higher in group B and C than that of group A(p<0.005). 2) Pulmonary vascular resistance(PVR) was 88.2+/-34.9 dyne.sec.cm(-5) in group A. 137.8+/-74.5 dyne.sec.cm(-5) in group B and 173.9+/-77.5 dyne.sec.cm(-5) in group C. In group B and C, PVR was increased compared to that of group A(p<0.05, p<0.005, respectively). 3) Pulmonary capillary wedge pressure(PCWP) was 6.6+/-2.8 mmHg in groupa A. 9.9+/-2.9mmHg, and 9.6+/-3.6 mmHg in group C. PCWP in group B and C were higher than that of group A(p<0.005). 4) Systemic vascular resistance(SVR) was 1298+/-340 dyne.sec.cm(-5) in group A, 1466+/-362 dyne .sec.cm(-5) i group B and 2255+/-439 dyne.sec.cm(-5) in group C. In group C, SVR was increased compared to that of group A and B(p<0.002). 5) Significant correlation was demonstrated between PVR and PCWP in group A(r=-0.74, p<0.05). 6) In group B, significant correlations were shown between PAP and PCWp(r=0.55, p<0.05), between PAP and PVR(r=0.69, p<0.05). 7) In group C, significant correlations were demonstrated between PAP and PCWP(r=0.55, p<0.05), between PVR and SVR(r=<0.51, p<0.01). Above results revealed that PAP and PVR were increased in essential hypertensives without left ventricular failure and this elevated PAPseemed to be affected in part by increased PCWP, and increased PVR in accordance with increased SVR.

Congenital dislocation of the hip has been known as one of the most common congenital anomalies in the orthopedic field since the time of Hippocrates (460-357 B.C.). The occurence of C.D.H. in twin babies is extremely rare thus few if any papers have been reported. During the period of January 1971 through June 1976 the authors have treated a total of 49 cases as inpatients. Two of these were twin babies. In both cases the hip was surgically reduced and followed by open reduction and femoral derotation osteotomy. Clinically and radiologically the results were good during the duration of follow-up seven months after operations.

A case of the brain death confirmed by isotope angiogrphy is described. Isotope angiography is a simple and noninvasive technic compared to carotid angiography, and is recommended as a reliable test for the diagnosis of brain death.

We report a caae of hepatic and intestinal infestation with paragonimus wewstermani complicating abscess formation. The pathway by which the paragonimus westermani reaehea liver and intestine is not well understood. However, there was possiblity that it may become lodged in other organs that the lung because of polonged larval migrations through the diaphragm or into various sites in the abdomen. The patient, 52-year-old female gave a history of having reyeatedly consumed raw crabs. An x-ray film of the chest showed clear lunga Skin test for paragonimus-westermani was positive. Abdominal ultrasonogram showed enlargement of the liver with multiple hypoechoic lesiona ERCP revealed multiple ie lesions in the right lobe of the liver. Abdaminal CT showed multifocal abscess cavities with slight rim enhancements. Above meetioned diagnostic procedures suggested liver abscess or hepatoma. Then, an exploratory laparotomy was done for a definite diagnosis, Frozen biopsy, from liver and surgically exe mass from ileocecal region revealed extrpulmonary paragnomiasis involving liver and cecum. Thus, the patient was treated with prasiquantel. Three months later, abdominal ultrasonogram demonstrated slight enlargement of the liver but no evidence of abnormal mass like lesions.

In order to study the development of fungal keratitis in wearing of the soft contact lenses contaminated with fungus in various conditions of the cornea, we contaminated the soft contact lenses with Candida albicans, and then placed them on the corneas in rabbits. The rabbits were divided into 4 groups(each 8 eyes). In group 1, dexamethasone was injected subconjunctivally once a day for 4 days and the corneal epithelium was removed 7mm in diameter. In group 2, dexamethasone was injected subconjunctivally once a day for 4 days without removal of the corneal epithelium. In group 3, the corneal epithelium was removed 7mm in diameter without subconjunctival injection of dexamethasone. In group 4, normal corneas were used as a control. The corneas were observed daily with slit-lamp. After 10 days, the infected corneas were examined with light microscope. Keratitis was developed in 5 eyes in group 1(5/8), 3 eyes in group 2(3/8), 2 eyes in group 3(2/8). But keratitis was not developed in group 4. Light microscopic examination showed active invasion of C, albicans forming pseudohyphae into the cornea associated with severe inflammation in group 1 and 2, but it showed mild inflammation and only a small number of C, albicans in the superficial cornea in group 3. In this study, it was found that immunosuppressed and de-epithelialized corneas are susceptible to C, albicans.
