The proteins, especially the 19S globulin (IgM) and 7S globulin (IgA) in the CO2 snow-induced blister fluids of 10 male healty volunteers were analyzed immunoelectrophoretically. The fnllawing results were obtained. 1) Compared with autologous serum, all blister fluids tested lacked some protein fraction lines. 2) The 19S globulin (lgM) line was absent in all of the blister fluids except one which was contaminated with blood. 3) The 7S globulin (IgA) line was present in all of the blister fluids when undiluted. In 1 : 2 dilution, however, it was absent, or of trace amount in a few cases.

Persistent pupillary membranes are common congenital disorders. To reduce the surgical complications, we used vitreous scissors instead of conventionally used Vannas scissors to remove the membrane and reviewed the surgical results. Five eyes of 4 children with persistent pupillary membrane were treated by surgery. Through the 1.5 mm limbal incision, the membrane was removed by using vitreous scissors after intracameral sodium hyaluronate. After 22.6 months follow-up, all pupils of operated eyes were round and no complications associated with the surgery were found. Three eyes showed improved visual acuities after the operation. We suggest that the surgery with vitreous scissors is better than with Vannas scissors.

The authors report the incidence of myopia in a group of premature infants with birth weights of less than 1500g and/or gestational age less than 33 weeks. One hundred sixty eight babies who were born in one hospital from Jan. 1991 to Dec. 1993 were included. Eyes were refracted using cycloplegic retinoscopy at 6 months after term. Myopia was observed in 49.8% of the refracted eyes. High myopia was observed in 1.4%. The history of acute retinopathy of prematurity was not associated with the development of myopia or high myopia(Fishers exact test, p>0.05), but the history of threshold retinopathy of prematurity was associated with the high incidence of myopia and high myopia(Chi-square test, p<0.05).

Malaria is one of the most important parasitic diseases especially in tropical areas. Over 300 million people are affected and the condition causes 1-3 million deaths each year. It is transmitted by the bite of infected Anopheles mosquitoes. Although Korea was declared to be free of Malaria by the WHO in 1979, malaria re-emergence has been apparent since 1993 amongst soldiers located near the De-Militarized Zone (DMZ) in the northern part of the country. Conventional microscopic examination of thin and thick blood films demonstrates the presence of the parasite and thus this method has been used to confirm the diagnosis of malaria, but it is a labor-intensive procedure and relies upon subjective interpretation. To overcome these limitations, fast and reliable methods for malaria detection have been recently introduced. In this study, we compared three kinds of antibody detection kits and one biochemical test kit that determines the presence of Plasmodium lactate dehydrogenase (pLDH) with conventional peripheral blood smears. The antibody detection methods examined were, two rapid test pack format methods and a single microplate format enzyme-linked immunosorbent assay (ELISA) kit, as manufactured by Korean companies. The sensitivities of the three commercial antibody detection kits in the early stage of malaria were 70.8%, 77.4%, and 63.6%, their corresponding specificities 90.5%, 91.8%, and 80.9%, and their accuracies 87.6%, 87.0%, and 76.7%. The sensitivity and specificity of the pLDH assay were 100% apiece and the results were in 100% concordance with the microscopy of thick blood films. Thus, the pLDH assay may be used as an alternative for conventional microscopic blood film examination, especially in emergency situations when prompt treatment is necessary.

Two cases of old unreduced radial head dislocation in children were experienced in this hospital. These were the results of neglected Monteggia fracture. Dislocated radial heads were reduced under direct vision and the anular ligaments were reconstructed. Follow up study taken 9 months and 6 years respectively after operation revealed excellent elbow motion including pronation and supination. The radial nerve palsy which had been developed in one of the two patients after injury was recovered spontaneously after reduction of the radial head without opening of the Arcade of Frohse. Then we are reporting these cases with a review of the literature.

Recently the fracture of patella has increasing tendency due to frequent traffic and industrial accidents. In this series, we treated 141 fractures of patella from January, 1980 to November, 1988 at the Department of Orthopedic surgery, Seoul Paik Hospital, Inje University, and obtained following re sults: 1. Peak age was third to fifth decades. 2. The most common cause of fracture was traffic accident. 3. Comminuted fracture was the most common type in this series. 4. Men predominate in a ratio of nearly 7:l. 5. 101 cases were treated with Modified Tension Band Wiring(41 cases), Tenison Band Wiring (21 cases), Partial Patellectomy(21 cases), Total Patellectomy(9 cases), Circumferential Wiring (9 cases). 6. The most favorable results were obtained by Modified Tension Band Wiring method as compared with other fixation techniques.

We reviewed MR angiograms to evaluate its efficacy for visualizing the renal arteries and detecting renovascular disease. 41 renal arteries in 19 patients were examined by MR angiography. 3-D time-of-flight technique was used as routine examination method for MR angiography and 2-D time-of-flight technique was added in some particular cases to visualize venous flow. Within two weeks after MR angiography was performed, 23 renal arteries in 10 patients were additionally examined by conventional angiography or intraarterial DSA. The success rates of vessel visualization on MR angiography in normal renal arteries were 100% in main 67.7% in segmental, and 11.8% in intrarenal arteries. As a result of comparative study in normal main renal arteries with MR angiograms and conventional angiograms, overall correspondence in the number and the shape was noted and the caliber discrepancy between two examination did not exceed 3.0 mm. one arteriovenous fistula with aneurysm, one stenotic artery and two occluded arteries were well evaluated One arteriovenous fistula with aneurysm, and two occluded arteries were well evaluated by MR angiography. However three stenotic lesions were misdiagnosed as occlusions on MR angiography. and the overall accuracy was 87%. We conclude that MR angiography has the potential to be a noninvasive and useful screening method for determining the number of renal arteries and for detection of abnormalities of main renal arteries.
