Colloidal gold 198Au were injected into 40 knee joints of rabbits for the study of the change of synovial membrane. We verified even distribution of Colloidal gold 198Au about knee joints by use of scintigraphy. After then, histopathological examinations were performed by periodic intervals. The following results are obtained form this study. l. Intra-articular injection of Colloidal gold 198Au into rabbit's knee joints resulted in a mild resctive inflammation at synovium. In was charscterized by an infiltration of eosinophils and by sclerotic changes in the subsynovium and by fibrosis of synovial vessels. 2. From this study, intra-articular injection of Colloidal gold 198Au may by benefit to treat the chronic synovial effusion in human.

In fusion of lumbar spine, every fused motion segments shows varisble limitation of motion in flexion, extension and lateral bending according to their types and level of fusion. The motion segment of lumbar spine is three joint complex which consists of posterior two articular facet joints and an anterior intervertebral disc. Nowadays, orthopedic surgeon prefer anterior fusion due to direct identification and removal of diseased tissue, reduction of fractured fragments, restoration of intrevertebral space, early rehabilitation and no damage of nerve root and cord, and is prefered short Segmental Spinal Instrumentation(e.g. Cotrel Dubousset Instrumentation, etc.) due to short and rigid fusion, no necessity of external support and low limitation of motion. We studied 58 cases of fused lumbar spine which had been operated since Sep.1983, by X-ray overlay method and 20 cases of healthy lumbar spine as eontrol group. In this study, we obtained following results ; 1. Harrington Rod Instrumentation reveals the most remarkable limitation of motion, whereas, C.D.I. and A.I.F. reveal the least limitation of motion. 2. Distinct differencies of motion are repersented by its range of fusion and range of motion in 2 segmental fusion reveals remarkable decreasement from range of motion in single segmental fusion. 3. In single segmental fusion, the most limitation of motion was represented in Harrington Rod Instrumentation and posterior fusion with bone graft. There is remarkable decreasement of flexion at lumbosacral junction by its site of fusion. 4.In double segmental fusion, the most limitation of motion was represented in Harrington Rod Instrumentation and there is no significant difference of motion by its site of fusion.

PURPOSE: To recanalize the occlusive lesion of superficial femoral artery at origin site by retrograde approach via popliteal artery. MATERIALS AND METHODS: 15 patients, who were poor surgical candidates due to coronary artery disease and who had severe occlusive lesion of superficial femoral artery close to its origin with good distal runoffs to popliteal artery, were selected. Patients were all~men and range of age were from 53 years to 66 years (mean age:63 years). Range of lesion length were from 15cm to 30cm (mean length:22.4cm). Localization of popliteal artery was done with Doppler stethoscope or "road-map" DSA. The method of recanalization were transluminal endarterectomy catheter (TEC), TEC and angioplasty, thrombolysoangioplasty (TLA). RESULT: Retrograde puncture of popliteal artery were done in 15 patients successfully. TEC & PTA was performed in 9 patients, TEC only in 2 patients, and TLA & PTA in 2 patients. During the follow-up period of 5 months to 2 years reocclusion did not occurr in 10 patients except for 1 patient with poor cardiac output in whom it occured 1 day later. Remained 4 patients were lost in follow up. Any neurologic or vascular complication did not occur. CONCLUSION: Retrograde approach of superficial fernoral artery via popliteal artery in patients with difficult vascular intervention by common method provides a useful, alternative recanalization method.

A possible therapeutic effect of acetyl-L carnitine (ALCAR) on peripheral nerve injuries and the expression of Jun, the protein products of immediate-early genes(IEGs), in the spinal cord were investigated after sciatic nerve injury in Sprague-Dawley rats. Experimental animals were divided into 3 groups: intact sciatic nerve as a control group, surgical repair alone, and surgical repair with ALCAR treatment. Toe-spreading response, pinprick response, and compound action potential were measured to evaluate the recovery of sciatic nerve injury. Recovery of behavioral function and electrophysiological function both improved in the surgical repair with ALCAR treatment group. Weak basal expression of Jun was shown in the ventral horn the of spinal cord in the control group. In the surgical repair alone group or the surgical repair with ALCAR treatment group, Jun expression persisted until 28 days after injury in the ventral horn of the spinal cord. Moreover, the surgical repair with ALCAR treatment group showed more increased expression of Jun than the surgical repair alone group. These results suggest that ALCAR facilitates the functional recovery after peripheral nerve injury.

OBJECTIVES: To study the distributions of pH and gas values in umbilical arterial(UA) blood of normal newborns following uncomplicated pregnancies and vaginal births. Methods: In 457 consecutive normal term infants who were born between March 1995 and June 1998, we examined the UA pH and blood gas values obtained immediately following delivery. Maternal inclusion criteria were defined as an uncomplicated singleton pregnancy and a normal full term spontaneous vaginal delivery. And also neonatal inclusion criteria were defined as a normal intrauterine growth appropriate for gestational age without any malformations and Apgar score of 7 or more at both one and five minutes after birth. Umbilical artery blood samples were collected at each birth and were evaluated for pH, carbon dioxide pressure (PaCO2), oxygen pressure (PaO2) and actual bicarbonate. RESULTS: Histogram of UA pH value resemble normal distribution curve. The lowest UA pH was 7.04 and the 10th percentile value was 7.23. The median UA pH was 7.31 and 5% was below 7.20. The lowest UA PaO2 was 4.6mmHg and the 10th percentile value was 11.5mmHg. The highest UA PaCO2 was 67.2mmHg and the 90th percentile value was 56.5mmHg. The lowest bicarbonate value was 13.2mmol/L and the 10th percentile value was 18.4mmol/L. CONCLUSION: The distributions of the UA pH and gas values of the collective of normal newborns were illustrated. None of the UA pH was below 7.0.

PURPOSE: Carnitine plays a key role in the oxidation of fatty acids by facilitating their transport. As very low birth weight(VLBW) infants receiving total parenteral nutrition(TPN) with limited oral intake are likely to be carnitine-deficient state, they require exogenous supplementation of carnitine, however, effects of it remains controversial. To demonstrate effects of parenteral camitine supplementation on fat metabolism, weight gain and clinical outcome. We analyzed plasma levels of biochemical markers, changes of weight, and incidence of complications in 23 VLBW infants receiving TPN. METHOD: We randomly assigned 23 VLBW infants(<32 wks of gestational age) receiving TPN to carnitine-supplemented(100mg/kg per day) group(n=10) and control(n=13). Plasma total (TC), free(FC), and acyl carnitine(AC) levels and serum cholesterol, triglyceride and free fatty acid levels were measured before and 2 weeks after carnitine supplementation. RESULT: Decrements in TC for 2 weeks were significantly lower in carnitine group(41.6umol/l->32.3umol/l) than control group(46.3umol/l->25.2umol/l)(p<0.05). Changes of FC and AC were similar in both groups. Levels of cholesterol and triglyreride were similar in both groups. Days of regaining birth weight were faster in carnitine group than control group(15.3+/-3.4 vs 20. 8+/-11.1 days)(p<0.05). Rate of weight gain for two weeks were significantly faster than carnitine group than control group(p<0.05). No significant differences in clinical outcome were found. CONCLUSIONS: Carnitine supplementation in VLBW infants receiving TPN has an supportive nutritional regimen in that it reduces decrement in carnitine level and facilitate weight gain.

Malignant fibrous histiocytoma (MFH) of the heart is a very rare disease. It is difficult to distinguish from myxoma which is most common benign cardiac tumor. Prognosis of malignant fibrous histiocytoma (MFH) of the heart is known to be fatal despite of medical and surgical treatment in contrast to benign tumors. A primary myxoid malignant fibrous histiocytoma of the left atrium was diagnosed in a 58 years old woman. The mass was removed incompletely by operation. The patient did not receive either chemotherapy or radiotherapy. However, the patient is still alive for more than fifteen months after the initial presentation. We report a case of malignant fi brous histiocytoma (MFH) with reviewing the current references.

Pseudoxanthoma elasticum (PXE) is an uncommon heritable disorder of elastin characterized by cutaneous, ocular and vascular abnormalities. Typical skin lesion shows yellowish papules and redundant skin folds on the neck, axilla and groin due to degeneration and calcification of elastic fibers in deep dermis. As in all heritable disorders of connective tissue, no curative therapy is presently know. Redundant and unsightly skin folds about the neck can be improved by surgery, but irregular papular lesion on skin does not improved by surgery. A-44-year-old female who had a skin lesion and angioid streak was treated as follows: Skin folds on the neck were excised successfully without any significant problem such as intraoperative bleeding, wound dehiscence or hypertrophic scar formation. To evaluate whether we could smooth the irregular skin surface due to multiple papules, laserbrasion with a SLT contack Nd:YAG laser system was performed experimentally on a limited area which was located on the right supracla-vicular area about 2 x 3cm in size. An acceptable aesthetic appearance was achieved with surgical excision 12 months after the operation. Biopsy of the laserbrasion site revealed disappearance of the calcium deposit. This study emphasizes the possibility of using laserbrasion in solving troblesome skin lesion of the PXE.
