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 retrospectively analysed plain radiographs and MR imaging of 16 conventional osteosarcoma cases(8 children, 8 adults) which underwent amputations or limb salvage operations. Pathologic correlation was performed with gross and microscopic sections to evaluate 1) whether the open epiphyseal plate can function as a barrier against transphyseal spread of osteosarcoma and 2) the diagnostic value of MR imaging for the detection of the detection of the epiphyseal involvement of osteosarcoma. In children with open epiphyseal plates, conventional radiographs suggested transphyseal tumor growth in one of eight cases(12.5% and MR imaging in seven cases(87.5%). Pathologic examination confirmed epiphyseal involvement in six of seven cases noted with MR imaging(75%). On the the other hand, in adult patients with closed epiphyseal plates, conventional radiographs showed transphyseal tumor growth in six of eight cases(75%), while MR imaging and pathologic exam demonstrated tumor invasion in all cases(100%). We conclude that open epiphyseal plate does not function as and effective barrier against tumor extension, and MR imaging is an excellent method in detecting the extent of transphyseal tumor growth.
