Eight dogs were experimentally infected with Sarcocystis by oral inoculation of cardiac muscle from naturally infected cattle. The infected dogs commenced discharging of sporocysts in the feces after 10 to 12 days of inoculation, and continued until 20 and 35 days after inoculation. Three dogs were reinfected with cardiac muscle from the naturally infected cattle. Sporocysts reappeared in the feces on 12 to 13 days after reinfection. Sarcocystis sporocysts collected from the experimentally infected dogs were fed to each of the two 30-day-old Korean native calves. The infected calves remained clinically normal, except for the high fever (> or = 40 degrees C) and decreased hematocrit values on day 30 to 40 post inoculation. Muscular cysts of Sarcocystis were found from infected calves on day 40 post inoculation. Proliferative forms of Sarcocystis were also observed in the muscle of infected calves. These results suggest that the Sarcocystis cruzi found in Korean native cattle has a 2-host life cycle with dogs as the definitive host and Korean native calves as the intermediate host.

The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.

A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

Thirteen patients were operated for cubital tunnel syndrome and followed for an average of 26 months postoperatively. Ten patients had a history of relevant trauma and three patients had degenerative osteoarthritis of the elbow. The average duration of symptoms was 18 months (range, 2 to 96 months). Diagnosis was made by physical examination, electromyography and nerve conduction study. Among these, nerve conduction study was found to be the most valuable diagnostic method for the patients with atypical clinical findings. Most of the operations were performed by anterior transposition of the ulnar nerve. At the most recent follow-up, the result was excellent in two patients, good in eight, and fair in three; thus ten patients(77%) showed satisfactory results. The rating system for ulnar neuropathy based on sensory, motor dysfunction and pain was useful for evaluating the operative results. The postoperative gain of score for pain and sensory function were larger than that of motor function. Factors known to influence the result of the operation (age, duration of symptom, history of trauma, method of operation) did not effect the outcome in this study. For successful operation, the ulnar nerve must be thoroughly examined, all possible levels of compression must be released and new foci of compression must be created.

At the present time, lidocaine is commonly used in ophthalmic surgery as a local anesthetic. Although it is safer than general anesthesia, visionthreatening and even life-threatening side effect can occur rarely. We report one case of visual loss combined with severe neurologic damage after local injection of lidocaine. Fifty-year-old male patient underwent phacoemulsification and IOL transscleral implantation with unplanned anterior vitrectomy after Nadbath-Ellis akinesia and retrobulbar anesthesia with lidocaine with 1:100,000 epinephrine. After operation, the patient had visual loss, facial palsy, total ophthalmoplegia, severe proptosis and submandibular swelling. There were no evidences of eyeball perforation, retrobulbar hemorrhage, and direct nerve injury. Although the mechanism of nerve injury is not well explainable, we suggest lidocaine toxic reaction. To our knowledge, This is the first reported case in the literature. We report this case with available literature review.

There are several rnethods to correct the tibial bony defect including resection, cement filling, autograft or allograft and metal augmentation. The purpose of this study is to find the adequate treatment method of tibia bony defect through analysis of the result with above methods. From Sep. 1993 to Dec. 1997, the authors analyzed 93 cases of tibial medial bony defect corrected by overresection of lateral condyle, allograft and metal wedge or block among 358 cases of primary total knee arthroplasty(TKA) operated at Asan Medical Center. All cases were devided into four groups according to the treatment method; group A(31 cases) with overresection of lateral condyle, group B(37 cases) with metal wedge, group C(21 cases) with metal block and group D(4 cases) with allograft. The mean follow up period was 23.6 months(12 56 months). The results were as follows, 1. There were no definite statistical difference between group A, B, C and D in HSS knee score, ROM, correction of deformity. But in group D, there is one case of loss of the correction. 2. Loosening of the implant was not noted, but 17 cases of mild bony resorption was found just beneath the implant. It was particularly prominent in group B(9 cases) than group A(5 cases) and C(3 cases). 3. Among 4 cases of allograft, one has developed collapse of allograft. 4. 3 cases of deep infection developed only in group C, which were followed by revision TKA. Although further follow up study should be carried out, we concluded that resection of lateral tibial condyle, allograft, metal augmentation is a good substitute to the correction of the tibial bony defect in primary TKA.

BACKGROUND: Vitiligo is considered as an autoimmune disorder due to the generation and presence of autoantibodies directed against melanocyte antigens in the patients sera. Previous studies have revealed an increased incidence of organ-specific autoantibodies in vitiligo patients. A number of studies have demonstrated an increased frequency of thyroid autoantibodies in vitiligo patients and vitiligo is commonly seen in patients with clinical thyroid diseases. OBJECTIVE: The aim of this study is to investigate the incidence of antithyroid antibodies in vitiligo patients and to correlate the presence of these antibodies with factors such as sex, age, activity of the disease, duration of the disease and the type of vitiligo. Another aim of this study is to compare the incidence of abnormal thyroid function in those who have antithyroid antibody and those who don't. METHODS: One hundred and fifty seven vitiligo patients who visited vitiligo clinic in Samsung medical center from January of 1995 to November of 1996 were enrolled in this study. Detection and titration of antithyroid antibodies were performed by immunoradiometric assay. RESULTS: Among 157 patients tested, 17(10.8%) patients had antithyroglobulin antibodies and 10(6.4%) patients had antimicrosomal antibodies. Five patients had both antibodies. Statistically meaningful data are as follows; 1) Antimicrosomal antibody appeared less frequently in patients of childhood-onset. 2) Antithyroglobulin antibody was detected more frequently in active disease. Fifty nine out of 157 patients were examined for thyroid function. Four out of 22 patients with antithyroid antibody had abnormal thyroid function. None out of 37 patients without antithyroid antibody had abnormal thyroid function. CONCLUSION: The incidence of antithyroid antibodies according to onset age and activity is contradictory to previous reports, therefore large scaled study will be necessary to draw a conclusion.

Urachal disease, a disorder where embryonic remnant of the cloaca and the allantois present after birth as a midline fibrous cord, is usually detected in infancy and childhood. But urachal disease in adults is rare. We report a case of a huge abscess derived from a urachal cyst in an adult. A 52-year-old man presented with peri-umbilical distension and abdominal pain for 2 weeks. Ultrasonography and abdominal computed tomography scan demonstrated a huge abscess derived from the abdominal wall. After prompt incision and drainage, the remaining abscess cavity was removed completely under general anesthesia. Pathologic report was consistent with urachal duct cyst, and the patient was discharged in a week without complication.
