An apparatus was designed, based on the principle of Grayson's internal calorimetry, for the determination of the choroidal blood flow with thermistor as a sensing element. Experiments with water; 10%, 20%, 30% and 50% gelatin solution; living and dead rabbit eye and enucleated human eye showed that there was a linear relationship between the thermal conductivities and the currents required to raise the heating thermistor by 1 degree. Thus it was found that the Carslaw's law could be applied in these experiments In rabbit's eyes, thermistors were introduced into the suprachoroidal space after separating the sclera from the underlying choroid. At the same time, one of the vortex veins was cut right after the vein emerge from the sclera, and the amount of blood was absorbed and weighed. The results showed that when the blood flow was in the lower range, the thermal conductivity increased abruptly. When the blood flow increased, the increase in the thermal conductivity was at a more slower rate. In the physiological range of blood flow, however, there was a linear relationship between the blood flow and the changes in the thermal conductivity.

Rectus sheath hematoma is an uncommon entity of the anterior abdominal wall and an unusual cause of painful abdominal mass. Rectus sheath hematoma have been in association with trauma, infections, debilitating disease, collagen vascular disease, pregnancy. and the puerperium. Sudden disruption of a deep epigastric vessel may result in an abdominal wall hematoma, which depending upon its location and size, can produce symptoms and clinical findings compatible with a variety of acute intra-abdominal conditions. Such hematoma are infrequently encountered and early accurate diagnosis could prevent surgical intervention. Unfortunately, the clinical manifestations of rectus muscle hematoma are sometimes so dramatic that laparotomy is performed under the belief that intra-abdominal pathology is present. The diagnosis was confirmed at surgery in both patient. We present two cases of rectus sheath hematoma which were diagnosed by clinical & ultrasound examination preoperatively.

BACKGROUND: Cell-cell adhesion in tissue is mainly regulated by hornotypic interaction of cadherin molecules, which are anchored to the cytoskeleton via cytoplasmic proteins, including a-and / 3-catenin. Loss of E-cadherin and catenin have been attributed a pathogenetic role in tumor invasion. METHODS: We examined the expression of E-cadherin and a-catenin in human thyroid carcinoma by immunohistochemistry. RESULTS: Normal tissue strongly expressed E-cadherin and a-catenin. However, E-cadherin and a-catenin expression were frequently reduced in thyroid carcinoma (E-cadherin: 62.5%, a-catenin: 81.3%). But the expression of E-cadherin and a-catenin in tumors with metastatic spreading were not different with tumors without metastasis. CONCLUSION: These results suggest that reduced E-eadherin and a-catenin expression may be a sensitive marker for disturbance in the adhesive function of the junctional complex, but further evaluation with more cases is needed for confirmation of the result of the same degree of expression in tumors with metastasis.

The concept of surface replacement arthroplasty of the hip is to replace the diseased joint surface with artificial plastic and metal cup in the acetabular and femoral head respectively, and to restore the normal anatomy and gain biomechanical function. Ten cases of Wagner type's surface replacement arthroplasty performed in Department of Orthopedic Surgery, Seoul National University Hospital since July 1979 are reviewed, and their minimum follow up is two months. In terms of the Pain control and improvement of range of motion in the hip, surface replacement arthroplasty showed about the same result compared with conventional total hip. In our cases there was no one complicatian, even though it is too short to evaluate the result of this operation. Wagner recommends surface replacement arthroplasty to perform through anterior approach, but 2 cases of our ten patients that have relatively good range of motion of the hip could be operated on this surgery by anterolateral approach (oblique skin incision) without trochanteric osteotomy, because of high incedence of myositis ossification with anterior approach. It is our conclusion that surface replacement arthroplasty of the hip may be used as an interim procedure to gain time in young patient who needs conventional total hip replacement which reveals increasing complication with the lapse of time.

Twelve neglected congenital dislocations of the hip in ten patients over the age of eight years were treated by open reduction and chiari osteotomy. Reduction was aided by preoperative traction only in two hips, by femoral shortening with preoperative traction in three and by femoral shortening only in seven. The average follow up period in our series is 3 years, ranging from 1 year and 2 moths to 4 years and 5 months. The overall results were good but one case of avascular necrcsis and one case of redislocation were seen. By our experience it is thought that all old and congenitally dislocated hip in the growing age can be reduced by femoral shortening with soft tissue release, and preoperative traction for its reduction is not undispensable. The most problem in the treatment of the old congenital dislocation of the hip is the postoperative partial ankylosis in the affected hip and this problem would be overcome by delicate operative technique and meticulous hemostasis.

Authors performed 25 corneal grafts in 24 patients since the inauguration of The Central Eye Bank, attached to the Department of Ophthalmology, St. Mary's Hospital, Catholic Medical College, in April 19, 1967. Method and results of these cases are as follows; METHOD: In technique of surgery, the grafts in most of the cases were 7 mm in diameter(Table 3), in two types of penetrating and lamellar corneal grafts(Table 4). The donor material came from patient age group of 51-60 years old in most and was used within 24 hours after death (Table 5). In most cases we placed 12 interrupted sutures except of two cases for continuous suture by 8-0 virgin silks. Preoperative and postoperative cares were routine with systemic dexamethasone, 7.0mg a day was given routinely on the 5 th postoperative day for 30-50 days because of prevention of graft rejection. RESULTS AND SUMMARY: Table 7 summbrizes the results of our observation. Nineteen of the 25 grafts remained clear. And there was improved vision above 20/200 in ten eyes out of nineteen clear grafts. Table 10 lists the reasons why nine clear grafts did not improve vision. Postoperative complications occurred in fourteen grafts (Table 11). Penetrating corneal grafts for adherent leucoma courneae, staphyloma corneae and corneal scars from alkaline burn were failed to maintaining the clear graft. The donor material, the recipient cornea, graft rejection as a complication and its prevantion were discussed. ACKNOWLEDGEMENTS: We wish to express our sincere gratitude to an those who have guided in carrying out the present investigation. In particular, We are jndebted to Dr. Bon Sool Koo, Former Chief and Professor, Department of Ophthalmology, Catholic Medical College. Dr. Sang Wook Rhee. Chief and Associate Professor, Department of Ophthalmology, Catholic Medical College.
