Lipocortin represents a family of similar Ca++ depentent phospholipid-binding proteins capable of blocking the activity of phospholipase A2 (PLA2) in vitro. Generally, these proteins are believed to inhibit the release of arachidonic acid from photopholipids and the formation of lipid mediators such as prostaglandin, leukotriene, and platelet activating factor. Lipocortin 1, initially identified as a glucocorticoid- responsive protein in macrophages and neutrophils has been implicated in transmembrane signal transduction during growth factor-mediated cell proliferation and transformation. To define the synthesis and its regulation, we investigated the expression of lipocortin 1 in both the mRNA and protein level in U937 cell line in the presence of several differentiation factors. The results were as follows. 1. The expression of lipocortin 1 and its mRNA was increased during TPA-induced differentiation of U937 cells to maximum of 2-fold and 5-fold respectively. Both the protein and mRNA levels decreased after 48 hours. 2. With the treatment with IFN-gamma, the expression of CD16 was increased. However, the protein and mRNA levels of lipocortin 1 were, not changed significantly. 3. Neither the dexamethasone or hydrocortisone have any effects on the expression of lipocortin 1 in both TPA-differentiated and undifferentiated U937 cells. The results from this study would give a light on defining the functional role of lipocortin 1 in macro-moncycle cell lineage and possibly some informative clues for the pathogenic mechanisms of the inflammatory diseases.

We report s case of angiokeratoma of the vulva occuring in a 36-year-old woman. Numerous grayish dark purple papulovesicular lesions, ranging from 0.2 to 2.0mm in size, were observed on the right labium majus. All lesions were excised under local snesthesia after the diagnosis of angio keratoma was made histopathologically. No new lesions appeared during the follow-up period of one year.

Dynamic cardiomyoplasty is a recently introduced surgical method to improve myocardial performance. It consists of a placement of a skeletal muscle flap around the heart and stimulation of the flap in synchrony with ventricular contraction. We experienced a case of cardiomyoplasty in a 25 year old male patient with congestive heart failure. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. The operation was performed for 8hrs without cardiopulmonary bypass and the patient was transferred to the intensive care unit. He was mechanically ventilated electively overnight and extubation was done 18hrs postoperatively. The patient was discharged home on the 40days after operation and improved in exercise tolerance. We report the anesthetic management and hemodynamic changes in a patient who underwent dynamic cardiomyoplasty.

7.Evaluation for the Accuracy of the SRK/T Formula in PCL Implanted Patients(II): Optimizing, A-Constant.

To evaluate the efficacy of optimizing of A-constant, the error in prediction was analyzed in three groups of eyes after posterior chamber lens implantation ; 102 eyes with bag placed, 66 eyes with simple sulcus places, and 25 eyes with sulcus placed with transscleral fixation suture. We compared the predictive accuracy of the SRK/T formula using optimized A-constant (bag-placed, sulcus-placed) derived from the 300 eyes with Holladay and SRK/T using original surgeon factor and A-constant. The SRK/T formula with optimized A-constant has a better mean relative, absolut, and standard error and has a better range of IOL prediction error, which was more accurate than other formulas without optimizing. In this study it is our recommendation that each surgeon use a different optimized A-constants for sulcus or bag placement to enhance the predictability of the postoperative refraction.

Pulmonary metastasis occurs frequently in patients with gestational choriocarcinoma and most of these patients achieve remission with chemotherapy alone. Thus, the indications for surgical intervention are limited, but in appropriately selected patients, resection of a chemotherapy-resistant lung lesion can be curative. We have experienced that pulmonary metastatic choriocarcinoma in a drug-resistant patient was cured by pulmonary resection. So we report this case with a brief review of literatures.

Horizontal tear of the meniscus occurs most commonly in older patients. The tear begins initially with a simple horizontal cleavage which divides the meniscus into superior and inferior leaves resembling a fish mouth and which may become a flap or more complex tear with time if subjected to repeated injury. Thirty-four patients(36knees/40menisci) with horizontal tear of the meniscus, treated with arthroscopic partial meniscectomy except in 3 extensive tears at Ulsan University Hospital from Jan. 1993 to Jun. 1996, were analyzed to investigate the factors that may be associated with this type of meniscal tear, and the results were as follows; 1. The tears commonly occurred in labor workers(61.7%) and without obvious trauma history(67.6%), and the average age at the time of surgery was 44 years. 2. The most common site of the tear was posterior horn of the medial meniscus (62.5%). 3. The 40 horizontal tears consisted of 12 horizontaVcleavage(30%), 3 horizontaVflap(7.5%), and 25 horizontaUdegenerative complex tears(62.5%). 4. Degenerative changes were frequently noted in both arthroscopy(69.5%) and roentgenography (72.2%).

Since 1957, multiple possible mechanisms have been suggested to explain the production of the osteonecrosis of the femoral head and it is now accepted that steroid medication is one of the etiologic factors producing osteonecrosis of the femoral head. Among the surgical procedures in ischemic osteonercrosis of the femoral head are bone grafting, core decom-pression, rotational osteotomy, angulation osteotomy, hemiarthroplasty and total hip replacement. The choice of surgical procedures in the management of idiopathic osteonecrosis of the femoral head is dependent on several factors. Most important are the etiology and stage of the lesion. Other considerations are the patients age, lifestyle, and demands on his hip, and the surgeons preference and expertise. We reviewed 32 total hip replacements in 22 patients, which had been performed to treat steroid-induced osteonecrosis of the femoral head at Department of Orthopaedic Surgery, National Medical Center from Jan. 1975 to Dec. 1981. The longest follow-up was 7 years and 6 months and the shortest, 1 year, the average being 2 years and 6 months. The results were as follows: 1. There were 13 males and 9 females and more than half were in 5th decade. 2. Principal causes to use oral corticosteroids were rheumatoid arthritis, arthralgia, and low back pain in the order of frequency. 3. Duration of corticosteroid medication was between 2 months and 12 years and 18 patients took more than 12 months. 4. Of 18 patients who had the bilateral involvement, the two also had osteonecrosis of the humeral head. 5. Roentgenographically, 30 hips were in stage IV and 2, in stage III according to the classification of Arlet and Ficat. 6. Types of the implants used were Charnely (28 cases), MQller (2 cases) and Trapezoidal-28 (3 cases). 7. The function of the each hip was evaluated preoperatively and postoperatively by the method of Wilson and Salvati and all improved from average poor to average good.
