OBJECTIVE: To determine the differences of expression of Transforming Growth Factor (TGF)-beta1 and TGF-beta2 in the human proliferative, secretory, menopausal endometrium, and in hyperplasia and adenocarcinoma of the endometrium. MATERIALS AND METHODS: Fifty patients were divided into 5 groups. Twenty samples were collected from patients with endometrial hyperplasia (n=l0) and adenocarcinoma(n=10) after hysterectomy. Thirty samples were collected from the normal menstrual cycle and the menopausal women as a control group. The histological types of endometrium were proliferative(n=10), secretory(n=10), menopausal(n=10). Immunohistochemical staining was performed through the use of monoclonal antibodies against anti-human TGF-beta1/ beta2 polycolonal IgG rabbit antibody. Expression of TGF-beta1 and TGF-beta2 were judged positive when the staining revealed color development in 5% or more. Specimens were rated absent, trace, weak, moderate and intense. Then, they were scored 4 in case of intense positive for TGF-beta1 and TGF-beta2, and '0' in case of absent for TGF-beta1 and TGF-beta2 . RESULTS: Mean scores of TGF-beta1 in glandular cell were proliferative(1.0), secretory (2.3), menopausal endometrium(1.0), endometrial hyperplasia(0) and adenocarcinoma(0). Expression of TGF-beta2 in glandular cell were proliferative(3.8), secretory(3.3), menopausal endometrium(2.8), endometrial hyperplasia(0.3) and adenocarcinoma(0.3). No specific different expression of TGF-beta1 and TGF-beta2 was found between stromal, vascular and myometrium. However, there was similar expression of TGF-beta1 and TGF-beta2 in endometrial hyperplasia and adenocarcinoma gmup. CONCLUSIONS: TGF-beta1 and TGF-beta2 may have important roles to suppress the development of the precancerous or cancerous lesions in endometrial glandular cells.

We have experienced 11 cases of large bony defect that were treated using microsurgery since 1981. Free vascularized bone transplantation was performed in 8 of them, vascularized bone transposition in 2 cases, and free vascularized joint transplantation in the remaining 1 case. The causes of the large bony defect were primary bone tumor (4 cases), congenital pseudoarthrosis (3 cases), open comminuted fracture (2 cases), sequela of osteomyelitis (1 case), and post-traumatic ankylosis of PIP joint of second finger (1 case). As a donor, fibula was used in 8 cases, iliac crest in 1 case, rib in 1 case and in the remaining 1 case, the second M-P joint of foot was transplanted. In 9 of 11 cases, successful result was obtained and 2 cases were failed because of vascular damage following tibial lengthening in one case and infection on the grafted area in the other one. From the above data and review of articles, following conclusions were obtained. 1. Fibula is thought to be the most appropriate donor for the large bony defect in the extremity, especially in lower extremity, but the donor site must be determined according to the anatomical and physilogical condition of the patient. 2. After mechanical lengthening of the extremity, it is recommened to perform the microvascular surgery after sufficient time for the recovery of vascular damage. But further studies are required for the identification of the change in the vascular tissue following stretching and its recovery time. 3. Progression of the ossification in the epiphysis of transplanted iliac crest was observed and this finding proposed us the idea that the epiphyseal plate injury or leg length discrepancy will be able to be treated with free vascularized epiphyseal plate transplantation and the reconstruction of the destroyed joint of growing children will be possible using free vascularized joint transplantation. 4. As the technique become more popular, the free vascularized bone transplantation is being used for the reconstruction of the extremity more frequently, but it seems to be wise to restrict its indication to cases which are impossible to be treated with more simple methods such as vascularized bone transposition or pedicled bone graft.

To evaluate the value of MR imaging in the examination of ligament injury of the knee, we retrospectively analysed the MR images of 61 injured knees of 60 patients. The presence of tear was determined by arthroscopy in all cases. Anterior/posterior cruciate ligaments(ACL/PCL) were demonstrated by sagittal images. Media/lateral collateral ligaments(MCL/LCL) were evaluated on coronal images. The diagnostic accuracy were 91.8%, 96.7% and 100% for ACL, PCL and MCL, respectively. The specificity for the lateral collateral ligament was 100%. It is concluded that magnetic resonance imaging is an accurate method in detecting injury of the ligaments of the knee.

PURPOSE: To evaluate the findings and the role of contrast enhanced magnetic resonance imaging in avascular necrosis of femoral head. MATERIALS AND METHODS: Sixteen patients with avascular necrosis of femoral head were examined with MRI. Tl-weighted and T2-weighted images and contrast-enhanced Tl-weighted images were obtained. Enhancing characteristics of the necrotic area and synovium were determined. Also a change of the disease extent after enhancement was assessed. RESULTS: Twenty seven avascular necrosis of the femoral head including 11 cases of bilateral lesion were detected. Fifteen cases revealed collapse of the femoral head. The portions of the lesion with low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images showed contrast enhancement in 15 cases. However, the portions with low signal intensities both on T1 and T2-weighted images showed enhancement in one case. There was no significant change of the disease extent after enhancement. Synovium showed enhancement in 18 cases, and joint effusion was detected in 23 cases. CONCLUSION: Contrast enhanced MR images may be helpful in predicting histopathologic findings of avascular necrosis of the femoral head, but not useful for evaluating the extent of disease.

To evaluate the role of magnetic resonance(MR) imaging in the diagnosis of the discoid meniscus, the authors reviewed 31 cases of discoid menisci diagnosed by MR imaging among which 16 cases received arthroscopy. Using knee surface coil, sagittal T1, T2, & protein density images and coronal T1 weighted images were obtained with 18 cm FOV & 4mm/1 mm thickness/gap. A discoid meniscus was considered if three or more contiguous sagittal images demonstrated continuity of the meniscus between the anterior and posterior horns or the diameter of the mid-portion of the meniscus exceeded 15 mm on the coronal image. The authors also observed the associated abnormalities including tears of meniscus and ligament, meniscal cyst, and osteochondral defects. All discoid menisci were lateral menisci and torn discoid lateral menisci were present in 26 cases(83%). In two cases, tears of the contralateral medial meniscus were present. The tears of anterior and posterior cruciate ligaments, meniscal cyst, and osteochondral defects were present in 4, 2, 4, and 5 cases respectively. All collateral ligaments were intact. In conclusion MR imaging was useful for the detection of discoid meniscus and associated abnormalities.

BACKGROUND: Although surgical angioplasty for isolated coronary ostial stenosis is assumend as an alternative approach to CABG, the clinical features of isolated coronary ostial stenosis, postoperative complications and follow-up angiographic results would have not been well studied. METHODS: We retrospectively studied 24 patients (female : male = 20 : 4, mean age 50.0 +/- 12.3 yr) who underwent surgical angioplasty for isolated coronary ostial stenosis using patch ( 22 fresh autologous pericardium, 2 saphenous vein) during the period of March 1990 through February 1998. Repeat coronary angiography (16 patients) and echocardiography (24 patients) were performed. Aortic regurgitation was evaluated semiquantitatively (Grade I - Grade IV). RESULTS: There were 3 deaths after surgical angioplasty. One death was due to acute coronary dissection perioperatively, the second due to low cardiac output syndrome 2 weeks post-surgery, and the third due to traumatic panperitonitis 10 months post-procedure. Angina recurred in 4 patients and the remaning 18 patients were symptom-free. Repeat angiography (19.3 +/- 20.7 Mo) showed widely patent ostium with excellent run-off except 2 patients (1 distal patch stenosis, 1 ostial restenosis in Takayasu's arteritis). The third symptomatic patient was proven to have coronary spasm by ergonovine test. AR increased in the fourth patient (Grade II -> III) with patent ostium. CONCLUSION: Surgical angioplasty may be feasible and alternative operative method to CABG for isolated coronary ostial stenosis. It should however be noted that postop AR can develop and/or increase. Further investigation is needed to evaluate the clinical significance of the AR.

Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.
