The incidence of complications has greatly increased in proportion to the modernized and sophisticated urologic techniques. The following are the results of a clinical survey made for the operations and ensuing complications among the in-patients at the Department of Urology, Han Yang University Hospital during the period of May 1972-May 1978. 1. The operated cases were 840 out of 1160 hospitalized patients, giving a ration of 72.4%. 2. The methods of anesthesia were as follows ; General endotracheal anesthesia 648 (77. 1%), Spinal anesth. 72 (8.6%), Local anesth. 72 (8.6%), and Caudal anesth. 29(3.5%) 3. Total numbers of complications were 120 complications were noted among 42 cases of urethra operation. 27 cases of bladder operation. 15 cases of kidney operation, and so on. 4. Organ distribution of this complication were as follow ; kidney 15. ureter 12, bladder 27, prostate 4, urethra 42, and scrotum and its contents were 12. 5. The most commonly observed complication vas wound abscess which occurred in 25 cases (20.8%) out of the total number of 120 complications, eventhough each operation has its specific finding of complication.

PURPOSE: For the production and evaluation of the tissue-equivalent phantom. MATERIALS AND METHODS: We used agarous gel and oil as a basic component of the mixture and added Tween 80 for the stabilization of phantoms. We did the test for homogeneity and measured T1 and T2 relexation times of each phantom tube. RESULTS: T1 relaxation time ranged from 642 to 2781 msec and T2 relaxation times from 42 to 157 msec. Each phantom was significantly different in T1 relaxation time and T2 relaxation time (p < .0001). CONCLUSION: Tissue equivalent phantom may provide good information on the optimal sequence before MR imaging of patients and may be valuable if it is used with the patients' MR imaging.

Transforming growth factor-beta (TGF-beta) has been suspected as a possible gene therapy candidate for orthopedic diseases. We demonstrated that the TGF-beta gene therapy can be applicable to orthopedic patients. After transfection of TGF-beta cDNA sequence to myoblasts [C2 (280)] and fibroblasts (NIH 3T3), stable cell lines with TGF-beta mRNA expression were selected by Northern analysis. To evaluate the possibility of clinical application of these cells to orthopedic diseases, the cells were injected into rabbit achilles tendon. Intratendinous injection was done to evaluate the viability of the cells and to determine the optimal concentration for in vivo expression. At 6 weeks after injection, the injected tendon was thickened with newly formed collagen. The results from this experiment indicates that these cells survived and stimulated matrix formation in rabbit achilles tendon. We concluded that TGF-beta cDNA transfected cells can be useful in the evaluation of TGF-beta biology in vivo.

TGF-p receptor mutation is now considered as one of the carcinogenic process of many tumors. To evaluate whether there is an abnormality in TGF-p type II receptor in osteosarcoma cell lines, we performed Northern analysis, cross-linking assay, luciferase activity and TGF-p growth inhibition assay in four osteosarcoma cell lines: G292, U202, HOS and SaOS. We also transfected the tumor cells with normal TGF-p type II receptor sequence to find if there is a possibility of gene therapy in osteosarcoma. In Northern analysis, Type II receptor expressions were decreased at SaOS, U202 and HOS cell lines. In cross-linking assay, all four cell lines didnt show type II receptor at their cell surface. The growth of these tumor cells were not suppressed by TGF-p. From these findings, we concluded that the normal production of TGF-p type II receptor was impaired in osteosarcoma. The transfection of these tumor cells with normal type II receptor sequence restored growth inhibition by TGF-p. This means even though TGF-p type II receptor is abnormal in osteosarcoma, we can restore its function by transfection of normal sequence. We think that the TGF-p type Il receptor gene therapy can be one of the treatment method for osteosarcoma in the future.

Parkinsonism is a clinical syndrome with constellation of resting tremor, rigidity, bradykinesia, and a variety of gait disturbances. Gait disturbances in parkinsonism include short-stepped festination, loss of postural reflexes, and freezing. In certain parkinsonian states such as progressive supranuclear palsy, gait disturbances are very prominent over other clinical signs of parkinsonism in the early stage. However, freezing is usually seen in the late course of parkinsonism. Recently, it has been recognized that some patients have prominent freezing in their early course of the disease, and not much of other parkinsonian signs. The pathologies need to be confirmed, but must be divers based on clinical description of the cases. We report two elderly men who presented with pure freezing. There was minimal short-term memory impairment in the second case, but no other signs of parkinsonism were present. Brief trial of L-dopa did not offer much benefit. Detailed clinical features and laboratory findings will be presented with discussion of the literatures.

STUDY DESIGN: A review of literature including definition, diagnosis and treatment of neuropathic pain. OBJECTIVES: To review and discuss the treatment guideline for neuropathic pain. SUMMARY OF LITERATURE REVIEW: Neuropathic pains are characterized by partial or complete somatosensory change caused by various disorders affecting central and peripheral nervous system, and are especially problematic because of their severity, chronicity and resistance to simple analgesics. MATERIALS AND METHODS: Review of literature. RESULTS: Tricyclic antidepressants and the anticonvulsants gabapentin and pregablin were recommended as first-line treatments for neuropathic pain. Opioid analgesics and tramadol were recommended as second-line treatments that can be considered for first-line use in selected clinical circumstances. Other medications such as dual reuptake inhibitors of both serotonin and norepinephrine would be used in severe cases. More invasive interventions (e.g., spinal cord stimulation) may sometimes be helpful. CONCLUSIONS: Treatment must be individualized for each patient and aggressive, combinatory pharmacotherapy and multidisciplinary approach are recommended for the treatment of neuropathic pain.

The aim of this study was to determine the applicability of reverse transcription and polymerase chain reaction (RT/PCR) for routine diagnostic use and for the detection of enteroviral mentigitis. Primers were selected in the highly conserved part of the 5'-non-coding of the enteroviral genome. Enteroviral RNA was detected by the RT/PCR in routinely collected cerebrospinal fluids (CSF) of patients with aseptic meningitis who had admitted to the dept. Of Pediatrics. MinJoong Hospital, KonKuk University from May to July 1993. Enteroviral RNA was detected in one third of CSF specimen. Our results demonstrate the significance of the RT/PCR in the diagnosis of enteroviral meningitis.
