The application of the arthroscope to the shoulder joint has evolved in recent years for the purpose of diagnosis and treatment. This paper presented 11 cases with various shoulder diseases treated by arthroscopy during the period from January, 1984 to September, 1985 in the Department of Orthopedic Surgery, College of Medicine, Soon Chun Hyang University. The advantages of the arthroscopy were as follows: 1. The arthroscopy made it easier to diagnose the unsolved cases by direct biopsy on the pathologic lesions in the joint. 2. The damage on the inside and outside of the shoulder joint was minimal and the post-operative incision scar was acceptable cosmetically. 3. The limitation of the joint motion did not remain due to early exercise post-operatively. 4. The complications such as infection, neurovascular injury, scuffing of joint cartilage, etc. could be avoided.

Ganglion cysts of the cruciate ligament are quite rare. Ganglion cysts on the anterior cruciate ligament(ACL) should be suspected in any patient having pain and clicking sensation during terminal knee extension. A few cases have been reported concerning ganglion cysts present on the surface of the anterior cruciate ligament. We report three cases of a ganglion cysts on the ACL that was treated with arthroscopic excision.

The omentum has been used over the years for a variety of clinical problems. Recently it has shown that placing the omemtum on the brain and spinal cord can lead to an extensive development of vascular connections at the omental/CNS interface. Success with omental transposition to the human brain has led to increasing intreast in placing the omentum onto the human spinal cord. One paraplegic patient was chosen to enter into a feasibility study to see if omental transposition to their spianl cord might result in clinical benefit. The length of time from injury was about 21 months respecively. This patient had little, if any, motor and sensory function below umbilicus level. The operation required surgical lengthening of the pedicled omentum followed by its placement into a subcutaneous tunnel created backward along the lateral chest wall up to T-10, 11 level. An extensive thoracic laminectomy was then performed followed bya wide opening of the dura. In our case the cord showed segmental shrinkage of the spinal cord consistent with previous trauma. The omentum was laid directly onto the underlying spinal cord. Our observation for five months has shown that placement of the omentum onto the chronically injured spinal cord allowed for subsequent improvement in neuroelectrical activity, as manifested by reproducible somatosensory evoked potentials, and, more importantly, in moter function. It is considered that placing the omentum directly upon the brain or spinal cord may have the effect of either improving local vascular perfusion or, possibly, exerting some biochemicals(neurotransmitter), or as yet unknown, influence. But further observation is warranted to determine whether this improvement will be continued and will be observed in another cases.

OBJECTIVES: Recently, the main focus of etiologic study in schizophrenia has been directed to molecular genetic approach including polymorphism analysis. Abnormal immunoreactivity to IL-4 promoter and IL-4Ralpha has been identified in patients with schizophrenia. This study was designed to investigate the relationship between schizophrenia and immunologic influences by analyzing the polymorphisms of IL-4 promoter and IL-4Ralpha gene that are involved in interaction between immunologic system and CNS. METHODS: 222 schizophrenic patients diagnosed by DSM-IV and data of 165 normal controls obtained from Catholic Hemopoietic Stem Cell Information Bank, College of medicine, the Catholic University of Korea, were used in this study. DNA was extracted from whole blood and the polymorphic loci of IL-4 promoter and IL-4Ralphagene were amplified by polymerase chain reaction. Gene typing was performed by using SSCP and the results were assessed. The frequencies of allele and genotype were compared between patients and normal controls and between paranoid group and non-paranoid group. All data were analyzed chi2-test with two-tailed Fisher's exact test. RESULTS: 1) There were no significant differences in allele or genotype frequencies of IL-4 promoter and IL-4Ralpha between the group of schizophrenic patients and controls. 2) There were no significant differences in allele or genotype frequencies of IL-4 promoter and of IL-4Ralpaha between the group of paranoid schizophrenic patients and non-paranoid schizophrenic patients. CONCLSUION: These results suggest that polymorphisms of IL-4 promoter and IL-4Ralpha genes are unlikely related with the pathogenesis of schizophrenia.

The authors statistically analysed transferred patients among 110 ocular perforation injury patients who were admitted to the Seoul Paik Hospital between January 1, 1984 and December 31, 1988. Male was 85.9% and third decade was most common decades(30.5%). Left eye was more affected(59.8%) than right eye. The most common cause was traffic accident(37.%) and perforated site was corneo-sclera(43.%). Subconjunctival hemorrhage was the most common accompanied ocular manifestation(47.0%). Most of the perforated eyes were treated with primary closure of the wound. The final visual acuity was better in patients who were treated at only one hospital two or more hospitals before being transferred. With the above results, the final visual acuity may be related with the number of the hospital which the patients were treated before transferred.

BACKGROUND: The aim of this study was to examine the cardiac function and transcriptional response of the heart to propofol after ischemia-reperfusion. METHODS: Rat hearts were Langendorff-perfused using the modified Krebs-Henseleit buffer, and took 20 min stabilizing periods, 40 min ischemia periods, and then 120 min reperfusion period. The hearts were divided into 5 groups; Control: 180 min perfusion after stabilization, Ischemic: 40 min global ischemia after stabilization, followed by 120 min reperfusion, Pre: 2 micrometer propofol treatment was preformed only before ischemia, Post: 2 micrometer propofol treatment was performed only during reperfusion after ischemia, Pre/Post: 2 micrometer propofol treatment was performed both before and after ischemia. The measurement for cardiac performances, such as left ventricular developed pressure (LVDP), rate of left ventricular pressure generation (dP/dt), heart rate, and coronary flow were obtained. The expression profiles of isolated mRNA were determined by using Agilent microarray and real time-polymerase chain reaction (RT-PCR) was used to confirm the microarray results for a subset of genes. RESULTS: The Post group showed better LVDP and dP/dt than the Ischemic group. But there were no significant differences in heart rate and coronary flow among the groups. On the results of RT-PCR, the expressions of Abcc9, Bard1, and Casp4 were increased, but the expressions of Lyz, Casp8, and Timp1 were decreased in the Post group compared with the Ischemic group. CONCLUSIONS: This study suggests that 2 micrometer propofol may provide cardioprotective effect, and modulate gene expression such as apoptosis, and K(ATP) ion channel related-genes during reperfusion in the isolated rat hearts.

Future cell-based therapies such as tissue engineering will benefit from a source of autogenous pluripotent stem cells. There are embryonic stem cells (ESC) and autologous adult stem cells, two general types of stem cells potentilally useful for these applications. But practical use of ESC is limited due to potential problems of cell regulation and ethical considerations. To get bone marrow stem cells is relatively burden to patients because of pain, anesthesia requirement. The ideal stem cells are required of such as the following advantages: easy to obtain, minimal patient discomfort and a capability of yielding enough cell numbers. Adipose autologus tissue taken from intraoral fatty pad or abdomen may represent such a source. Our study designed to demonstrate the ability of human adipose tissue-derived stromal cells (hATSC) from human abdominal adipose tissue diffentiating into osteocyte and adipocyte under culture in vitro conditions. As a result of experiment, we identified stromal cell derived adipose tissue has the multilineage potentiality under appropriate culture conditions. And the adipose stromal cells expressed several mesenchymal stem cell related antigen (CD29, CD44) reactions. Secondary, we compared the culture results of a group of hATSC stimulated with TGF-beta1, bFGF with a hATSC group without growth factors to confirm whether cytokines have a important role of the proliferation in osteogenic differentiation. The role of cytokines such as TGF-beta1, bFGF increased hATSC's osteogenic differentiation especially when TGF-beta1 and bFGF were used together. These results suggest that adipose stromal cells with growth factors could be efficiently available for cell-based bone regeneration.

Epidural hemangioma is a rare neoplasm which consists of 4% of epidural tumors and 12% of hemangiomas of vertebral column. But most of them are secondary involvement of epidural space by vertebral hemangioma and pure epidural hemangioma is very rare. Reported cases involve thoracic & lumbar level. Neural foramen & paraspinal region are usually invaded by the tumor mass. Clinical symptoms are similar to simple low back pain or disc herniation. Myelography, CT & MRI are helpful to make diagnosis but pathologic finding is important for final diagnosis. Authors are reporting a case of epidural hemangioma which was difficult to differentiate from HIVD by symptomatology & radiologic findings alone.
