The extraction rates of biogenic amines such as 5-hydroxytryptamine(5-HT) and norepinephrine(NE) in pulmonary endothelium, and the permeability of human serum albumin(HSA) to pulmonary epithelium were measured in experimental adult respiratory distress syndrome(ARDS), in order to evaluate their usefulness for the early recognition of ARDS. Sixteen mongrel dogs(body weight, 13+/-0.9 kg) were divided into 3 groups; Oleic acid 0.06 ml/kg was injected to 6 dogs(M group) and oleic acid 0.12 ml/kg to 6 dogs(S group). Four dogs were used as a control group. The extraction rates(%) of 14C-5-HT and 3H-NE, the blood concentration of (99m)Tc-HSA, hemodynamic changes and changes of arterial gas profile were measured and compared among three groups. In control group with 100% oxygen ventilation, the extraction rates of 14C-5-HT, 3H-NE and the blood concentration of 99mTc-HSA were not changed. In M group, the extraction rate(%) of 14C-5-HT was decreased from 61.5+/-3.1 to 43.8+/-5.2 in 10 minutes, and such decreased extraction rate(%) was maintained for 2 hours. The extraction rate(%) of (3)H-NE was decreased from 32.3+/-3.6 to 19.5+/-2.5 in 10 minutes. In S group, the extraction rate(%) of 14C-5-HT was decreased from 60.9+/-5.1 to 23.2+/-5.7 in the first 10 minutes, and the extraction rate(%) of H-NE was decreased from 30.1+/-4.3 to l3.1+/-1.9 in 10 min, and decreased slowly thereafter. The blood concentration of 99mTc-HSA was decreased significantly in M group and more in S group compared with control group during two-hour observation. These results suggest that measuring extraction rates of biogenic amines couid be applied for early recognition of ARDS, however, the change of blood 99mTc-HSA concentration could not be applied for early recognition of ARDS, because it has poor correlation to the progression of respiratory failure.

In 20 patients of varicocele, both transscrotal and transfemoral phlebography to visualize the left renal, internal :spermatic and common iliac vein were performed during period from August, 1981 to March, 1982. The following results were obtained. 1. Among 14 pts. with passive reflux from the renal vein to the internal spermatic vein, proximal nutcracker phenomenon was observed in 10 patients, distal nutcracker phenomenon in 8 and both in 4. 2. Passive reflux to the internal spermatic vein without other abnormalities on phlebography was observed in 4 patients. Recurrent varicocele in 3 patient in this group who showed dilated duplicated internal spermatic veins were managed successfully by repeated high ligation. 3. In 2 patients showing renal-spermatic shunting vein and proximal nutcracker phenomenon concurrently, high ligation was performed distal to the point of the communication of shunting vein to the internal spermatic vein. 4. 8 patients with distal nutcracker phenomenon associated with passive reflux from the renal vein to the internal spermatic vein, I patient with distal nutcracker phenomenon and renal-spermatic shunt and 5 patients with normal venography were treated by ligation of internal spermatic vein, external spermatic vein and deferential vein through inguinal incision. 5. 1 patient with distal nutracker phenomenon without other abnormalities was managed by ligation of external spermatic and deferential vein at the level of internal inguinal ring. 6. Use of routine preoperative venography is essential to establish the etiology of the varicocele and its proper management.

We report a case of primary cardiac angiosarcoma in a 35 year-old woman. She presented with dyspnea, facial edema and neck vein distension during 1 month. The oval round large mass(8x4 cm) filling the right atrium infiltrated into the entire thickness of the lateral wall and extended to the vena cava and ventricle. The interatrial septum and pericardium seemed to be intact. Despite the surgical excision and adjuvant chemo-and radiotherapy, the patient died 8 months later due to tumor recurrence. The histologic findings of tumor varied from benign looking capillary proliferation mimicking granulation tissue to sarcoma composed of spindle cells. But anastomosing vascular channels lined by anaplastic polygonal cells and intracytoplasmic lumen containing red blood cells were characteristic findings. These tumor cells showed positive reaction to endothelial cell antigen and factor VIII-related antigen. The intercellular junctional complex and vascular channels formed by cytoplasmic process of tumor cells were identified by the ultrastructural study.

PURPOSE: To identify the changes of bony landmarks with rotation and to compare the reliability and accuracy of Perdriolle's method before and after training on the exact bony landmarks. MATERIALS AND METHODS: Simple A-P radiographs were taken with rotation from 5 degree to 50 degree at 5 degree interval using 10 dry human vertebrae (2 sets of T3, T6, T9 8 L3) with no bony abnormality. Axial rotation was measured before and after training on the exact bony landmarks by three observers, twice for each radiographs. Repeated measures of ANOVA were used for inter- < intraobserver variance and regression analysis for root mean square error and deviation of differences. RESULTS: Mamillary process, inner margin of lamina, proximal and distal costovertebral joints, upper margin of concave pedicle and tip of the transverse process on the convex side confused the exact outline of the pedicle, while neural foraminal margin was helpful in identifying the location of the indistinct convex pedicle and concave vertebral border. Of the 660 measurements before and after training 372 and 397 errors were made, respectively, of which 88.9% and 88.5% were within +/-5 degree(P > 0.05). Incidence of error greater than 5 degree was high at upper thoracic vertebra and 20 degree-40 degree of rotation regardless of training. The effects of training, however, was greatest at T3 and 20 degree-40 degree of rotation. Inter- < intraobserver variance was diminished at T3 and at the rotation between 20 degree-40 degree after training. CONCLUSIONS: We could conclude that training on the exact bony landmarks did not reduce the overall error incidence. Accuracy and reliability, however, was increased at T3 after training and the efficacy of training was more evident in moderate vertebral rotation than in small or large vertebral rotation.

Recently the esthetic demands of clinicians and patients made the surgeon try to regenerate bone defects and gingival tissue after extraction. For that, many surgical methods were used and socket preservation have been evaluated simple, effective and good prognosis in the implant placement. Bone grafting was one of the methods for socket preservation. This study was to evaluate the histologic view of the effects on healing of the extraction sockets when deproteinized bovine bone mineral and tetracycline coated deproteinized bovine bone mineral was implanted 1. In control group, at 4 weeks after implantation, the extraction sockets were filled with connective tissue. And after 8 weeks, osteoblasts were observed in newly formed trabecular among the fibrous connective tissue in the extraction sockets. 2. In experimental 1 group, there was connective tissue and new bone trabecular around newly formed woven bone at 4 weeks. And many osteoblasts were observed in various direction at 8 weeks. 3. In experimental 2 group, there was a lot of new bone made around the bone powder after 4 weeks, and the thicker bone trabecular, lamellar bone and irregular osteoblasts arrangement were observed at 8 weeks. From the results of this study, tetracycline coated BBP would be better than the other groups in the lamellar bone formation and be faster in the bone formation rate.
