The technique of the arthroscopic total meniscectomy of discoid meniscus is very difficult. Ikeuchi(1982) reported a technique of arthroscopic total meniscectomy of the lateral discoid meniscus by removal of 2/3 of the anterior part of the meniscus first and then by morselization. The purpose of this paper is to report a technique of arthroscopic total meniscectomy of the lateral discoid meniscus as a whole. During the period from October 1982 to October 1984, we had 12 experiences of arthroscopic total meniscectomy of the discoid meniscus and found good results, that is, little postoperative pain, short period of hospitalization and early restoration of joint motion without physical therapy. Complications are 3 cases of symptomless slight lateral instability and 4 cases of hemarthrosis.

The purpose of this study was to compare the anthropometry, the serum lipid levels and the nutrient intakes of two groups according to their alcohol intake, smoking habits, regular exercise patterns, menopause status and obesity levels. The subjects consisted of 180 clinically normal adults (males 89, females 91) in the Youngdong area. There were significant differences in the triglyceride (TG) concentrations between the alcohol consumers (169.3 +/- 130.0 mg/dl) and the non-alcohol consumers (111.4 +/- 64.5 mg/dl), and the smokers (165.0 +/- 103.6 mg/dl) and the non-smokers (110.8 +/- 39.0 mg/dl). Although regular exercise did not affect the serum lipid levels, the dietary intakes of cholesterol, niacin and phosphate were significantly higher (p < 0.05) in the male exercising group than in the male non-exercising group ; and female exercising group consumed more polyunsaturated fatty acids (p < 0.05) than the female non-exercising group. The waist/hip ratio, serum total cholesterol (198.4 +/- 36.3 mg/dl) and serum LDL-cholesterol (119.5 +/- 34.9 mg/dl) levels of the postmenopausal females were significantly higher than those of the premenopausal females (p < 0.01). The obese males showed higher serum cholesterol, LDL-cholesterol, LDL/HDL, and relative cholesterol levels than those of the normal-weight males ; and the obese females showed higher serum TG levels than that of the normal-weight females (p < 0.01). These results suggested that drinking, smoking, menopause and obesity are risk factors for hyperlipidemia. Thus, moderation in alcohol consumption, non-smoking, regular exercise and the maintenance of normal weight are necessary to prevent hyperlipidemia in middle-aged people.

OBJECTIVES: Brain transplantation has emerged as an effective treatment for patients suffering from neurodegenerative diseases, including Parkinson's disease, Huntingtons disease and Stroke. We evaluated that cytokine inducted human mesenchymal stem cells (Ci-hMSCs) transplanted in brain differentiated into neural cells and improved neurological functions after stroke in rats. MATERIALS AND METHODS: In the adult female Sprague-Dawley rats, ischemic lesion was induced by transient MCA occlusion lasted for 2 hours. One day later, Ci-hMSCs carrying LacZ gene were implanted via tail vein. The animals were assessed for sensorymotor function and sacrificed for Immunohistochemical staining at 7, 14, 28, 56 days after transplantation. RESULTS: A large number of X-gal positive hMSCs were observed in the ischemic core and ischemic boundary zone. Some hMSCs were reactive for the astrocytic marker - glial fibrillary acidic protein (GFAP) and neuronal marker - neuronal nuclear antigen (NeuN). The ischemic rats that were transplanted with Ci-hMSCs exhibited better functional improvement than control groups and the rats with hMSCs, which was statistically significant. CONCLUSION: The neuronal differentiation of CihMSCs suggested that transplantation of the Ci-hMSCs may provide the possibility of the clinical implication for cerebral stroke.

ATP-citrate lyase (ACL), an enzyme catalyzing the first step in biosynthesis of fatty acids, is induced during the lipogenesis and cholesterologenesis. We demonstrate that the region -213 to -128 of human ACL promoter is responsible for conferring glucose-mediated transcription. This region in the ACL promoter contains Sp1 binding sites determined by DNase I foot-printing assay. Gel retardation assay using oligonucleotides from -179 to -141 and -140 to -110 showed two specific DNA-protein complexes postulated to be formed by transcription factor Sp1. Competition gel shift and supershift assays have confirmed that these DNA-protein complexes were the result of induced Sp1 as well as another Sp1-related proteins. Western blot analysis also demonstrated that transcription factor Sp1 was slightly increased in the nuclear proteins extracted from Alexander cells following supplementation of glucose. In addition, expression of 110 kDa protein reacting with antibody against Sp3 was dramatically increased by glucose supplementation, while isoforms of Sp3, about 80 kDa in size was decreased in its amounts. Our results suggest that changes in the expression of Sp1 family proteins play an important role in activation of the ACL promoter by glucose.

Medial epicondylitis, also known as “golfer's elbow,” is a common overuse syndrome of the elbow and predominantly affects the origin of the common flexor tendon. We report two unique cases of medial epicondylitis complicated by chronic complete tear of the ulnar collateral ligament and common flexor tendon origin. Physical examination showed a focal huge swelling of medial epicondylar region of the dominant elbow and magnetic resonance imaging revealed complete tear of the ulnar collateral ligament and common flexor tendon and extravasation of intra-articular effusion. Satisfactory results were achieved with ulnar collateral ligament reconstruction and simultaneous repair of the common flexor tendon origin.

The purpose of this study is to evaluate the characteristics of posterior glenoid lesion (PGL) on magnetic resonance imaging (MRI) in adolescent baseball players. Seventy-two adolescent baseball players (mean age, 15.1 years) who underwent MRI scan for dominant shoulder pain were enrolled and the location and morphologic features of PGLs were assessed on MRI. All players were divided into three groups based on the physeal status of proximal humerus: group I, open; group II, partial closure; and group III, complete closure. Of the 72 players, posterior glenoid rim rounding (69%) and periosteal thickening (88%) were the main PGL on axial imaging. Osteochondritis dissecans (OCD) of glenoid (10%), Bennett lesion (6%), and posterior labral tear (21%) were also identified. On oblique sagittal imaging, bony PGL including OCD involves mid-portion of posterior glenoid consistent with the level of the infraspinatus muscle, but Bennett lesion was located relatively lower than PGL. Posterior glenoid rim rounding was more prevalent in younger players (group I, 86%; group II, 78%; group III, 43%; p=0.015), and posterior labral tears were in older players (group I, 0%; group II, 19%; group III, 38%, p=0.027). Factors related with prevalence of posterior glenoid rim rounding were increased body mass index (p=0.016), pitchers (p=0.024), and players with posterior shoulder tightness (p=0.023), but career length was not statistically significant (p=0.089). Decreasing the rate of posterior glenoid rim rounding with skeletal growth implies that it may be recovered through the remodeling process, and labral tears are increasing internal impingement lesion after physeal closure.

Surgery for pathologic hip fracture poses significant challenges regarding the fixation of fracture and management of the original tumor lesion. An extensive destruction of the femoral neck and intertrochanteric region by benign or malignant lesions complicated by a pathological fracture generally necessitates total hip arthroplasty; however, in adolescents and young adults, preservation of the hip is preferable. We present a 14-year-old female patient, who sustained a pathological intertrochanteric fracture through a pre-existing aneurysmal bone cyst. Several operative interventions with internal fixation and bone graft were unsuccessful, and combined nonunion and progression of osteolysis around the compression hip screw eventually caused femoral head collapse, mimicking osteonecrosis. Hip preservation and resolution of the original tumor were achieved by free vascularized fibular graft.

The nimodipine, calcium-channel blocker, is known to specific to brain tissue and effect on the ischemic stroke. To evaluate the efficacy and tolerability of nimodipine, we studied the 37 patients with Organic Brain Syndrome(OBS) who admitted to St. Mary's Hospital from January to August, 1989. We followed up for 12 weeks of their 18 items of neurologic outcome. The results and conclusion were as follows: 1) The pretreatment SCAG(Sandoz Clinical Assessment-Geriatric Scale) was used as a base-line measurement and the efficacy of the therapy was evaluated entirely in terms of changes in SCAG after 3, 6, 9 and 12 weeks of treatment. The total score was changed with meaningful improvement(p<0.01). 2) Among the 18 items of symptoms, the confusion, the level of alertness, the memory and the orientation were the area that have showed the most improvement. 3) No effect on heart, blood chemistry or other side effect was noted during medication. 4) We also found that those improvement has no specific relation to age, sex and causes of OBS. These result indicate that nimodipine has a possible therapeutic benefit in patients with OBS, especially who have the symptoms of confusion and impaired recent memory. These result should encouraged us to do further study such as double blind placebo in order to clarify the genuine pharmacological efficacy.

STUDY DESIGN: A retrospective study was designed to evaluate the clinical result and difference between short segment and long segment fixation, which was undertaken by posterior approach for thoracic and lumbar spine fractures. OBJECTIVE: To determine and compare the mechanical maintenance and ability of correction, and clinical and neurologic recov-ery between short segment and long segment fusion group. SUMMARY OF BACKGROUND DATA: The long segment instrumentation is a cause of decrease of motion segment in thoracic and lumbar spine. In short segment fusion, screw failures were reported. MATERIALS AND METHODS: From 1989 thorough 1997, 54 patients who had been operated on by the posterior approach with transpedicular screw fixation for spine injuries were divided into two groups. The authors applied the short segment transpedic-ular instrumentation including fractured vertebra. Short segment group included 35 cases, and long segment group, 19 cases. The mean follow-up period was one year and eight months for short segment group, two years and seven months for long segment one. The results were evaluated by comparing the anterior vertebral height, sagittal index in simple roentgenogram and neurologic recovery. RESULTS: The average of anterior vertebral height which was 50.7% at preoperation, became 78.7% after the operation and measured 74.9% at final follow-up in long segment fusion group, while in short segment fusion group it was 59.7%, 79.3% and 77.7%, respectively. The average of sagittal index of 17.5degreeat preoperation became 6.7degreeafter the operation, and measured 8degreeat final follow-up in long segment fusion group, while in short segment fusion group it was 19.9degree, 10.4degree, and 12.1degree, respectively. Overall clinical results had no statistical significant difference between two groups. Of the thirty-six patients with neurologic deficits, twenty-two improved by over the one Frankel grade. CONCLUSIONS: The authors conclude that the short segment transpedicular instrumentation including fractured vertebra is a successful method of thoracolumbar and lumbar burst fractures.
