Although uterine arterovenous malformation(AVM) is a rare cause of menorrhagia or postmenopausal bleeding, it is important to consider that curettage may precipitate life-threatening hemorrhage and therefore it is contraindicated when AVM is suspected. Special investigations such as hysteroscopy, Doppler flow ultrasound and angiography are important diagnostic tools, and transarterial embolization(TAE) has replaced hysterectomy as the treatment of choice in women who wish to retain their fertility. But due to the high incidence of collateral vessels, recurrence of the vascular malformation after TAE is common. We have experienced two cases of AVM, one of which was managed by TAE in combination with surgical arterial ligation.

Since 1967 the STA-MCA anastomosis has been popular procedure in neurosurgical operation. The meurosurgical teams at St. Paul's Hospital, Catholic Medical College, recently operated on 8 patients employing 9 times of this technique. The patients were diagnosed as four patients with complete stroke, one with traumatic middle cerebral stenosis, two with moyamoya disease, and one with huge aneurysm at intracavernous portion of ICA. The results were very encouraging of the 8 patients, 7 had favorably improved clinically, and proved by follow-up cerebral angiographies, CT Scanning, EEG or MEP recordings. The remaining one patient had intracerebral and intracerebellar hematoma, two months later after discharge, thus the result was poor. The authors would like to share with you their experiences employing the STA-MCA anastomosis technique, indications the results and the prognosis.

Steroid cell tumor of ovary, first described as lipid cell tumor, is rare lesions composed entirely of cells resembling typical steroid hormone - secreting cells, that is lutein cells, Leydig cells, and adrenal cortical cells. Steroid cell tumors oftcn secret androgen and manifest themselves with symptoms of virilization. Other presentations include abdominal swelling or pain, menstrual dysfunction, postmenopausal bleeding, or rarely ascites. We experienced a case of right ovarian steroid cell tumor, not otherwise specified(NOS), manifested hirsuitism and amenorrhea in 49 - year - old patient. The tumor was about 5 cm in size, and associated with huge ascites (l3,000 ml), both pleural effusion, and elevated serum CA 125. We present a case of Meigs syndrome associated with benign ovarian steroid cell tumor with a brief review of the literature.

OBJECTIVE: To evaluate the correlation of HPV infection and E6 oncoprotein expression with carcinogenesis and prognostic role of cervical carcinoma METHODS: Paraffin embedded tissues were obtained from 35 invasive cervical carcinoma, 15 carcinoma in situ, 12 dysplasia of cervix and 20 patients with benign uterine disease as control. HPV type was determined by polymerase chain reaction using type specific primers. E6 oncoprotein expression was analyzed by immunohistochemical staining using C1P5 mouse monoclonal antibody. RESULTS: 1. The positivity of HPV type 16 PCR in invasive cervical carcinoma was 77.1% and it was significantly higher than carcinoma in situ(53.3%), cervical dysplasia(25%), and control (10%). But the positivity of HPV type 18 was not correlated between above groups. 2. The positivity of HPV type 16/18 in cervical carcinoma was not correlated to patient's age. 3. The positivity of HPV in cervical carcinoma was correlated to clinical stage of cervical carcinoma but the positivity of HPV in cervical dysplasia was not correlated to the degree of dysplasia. 4. The positivity of E6 oncoprotein expression was 77.1% in invasive cervical carcinoma, 66.7% in carcinoma in situ and 20% in control group. E6 oncoprotein was not decteted among the cases which negative was for HPV 16/18. The E6 oncoprotein expression in 35 cases of invasive cervical carcinoma was negative in 8, weakly positive in 7, positive in 12, and strong positive in 8 ases. But in 20 cases of normal control group, there was no case of strong positive or posirive E6 oncoprotein expression. 5. The E6 oncoprotein expression was significantly correlated to the clinical stage and lymph node metastasis. The incidence of lymph node metastasis increased and the stage became higher as the E6 oncoprotein expression increased. CONCLUSION: These results suggest that HPV is one of the most important factors in the carcinogenesis of cervical carcinoma and the E6 oncoprotein expression may be associated with biological aggressiveness of cervical carcinoma.

PURPOSE: It is to report the efficacy and safety of an argon laser photocoagulation which was the treatment modality for retinopathy of prematurity. METHODS: From March 1996 to December 1999, on 69 prethreshold retinopathy of prematurity, they were series of observations following periods of two to five days, one week, two weeks, four weeks, three months and one year time respectively. RESULTS: We noticed the regressions in 84 prethreshold retinopathy of prematurity cases as well. CONCLUSIONS: The report emphasized the advantages of the argon laser photocoagulation which reduce the risk from a general anesthesia by applying a topical anesthesia, and the safety of using laser technique of convenience to apply and minimize the tissue damages of the lesions. It also described the preferable consequent results following the early treatment with divided applications on the prethreshold cases.

PURPOSE: Bone morphogenetic proteins (BMPs) play an important role in the formation of cartilage and bone, as well as regulating the growth of chondroblasts and osteoblasts. In this study, we investigated whether recombinant human BMP adenoviruses are available for ex vivo gene therapy, using human fibroblasts and human bone marrow stromal cells in an animal spinal fusion model. MATERIALS AND METHODS: Human fibroblasts and human bone marrow stromal cells were transduced with recombinant BMP-2 adenovirus (AdBMP-2) or recombinant BMP-7 adenovirus (AdBMP-7), referred to as AdBMP-7/BMSC, AdBMP-2/BMSC, AdBMP-7/HuFb, and AdBMP-2/HuFb. We showed that each cell secreted active BMPs by alkaline phosphatase staining. Since AdBMP-2 or AdBMP-7 tranducing cells were injected into the paravertebral muscle of athymic nude mice, at 4 weeks and 7 weeks, we confirmed that new bone formation occurred by induction of spinal fusion on radiographs and histochemical staining. RESULTS: In the region where the AdBMP-7/BMSC was injected, new bone formation was observed in all cases and spinal fusion was induced in two of these. AdBMP-2/BMSC induced bone formation and spinal fusion occurred among one of five. However, in the region where AdBMP/HuFb was injected, neither bone formation nor spinal fusion was observed. CONCLUSION: The osteoinductivity of AdBMP-7 was superior to that of AdBMP-2. In addition, the human bone marrow stromal cells were more efficient than the human fibroblasts for bone formation and spinal fusion. Therefore, the results of this study suggest that AdBMP-7/ BMSC would be the most useful approach to ex vivo gene therapy for an animal spinal fusion model.

PURPOSE: It has been reported that retinoic acid, one of the most popular agents for chemoprevention could inhibit the proliferation of many cancer cells including neuroblastoma and glioblastoma. However, there is increasing demand reaccessing its in vitro inhibitory effect on the tumor proliferation because of the poor results from recent clinical trials of retinoic acid in the malignant brain tumor. Retinoicacid ptomoted the diffferentiation and apoptosis of tumor cell so that its effect might be obvious in the pediatric brain tumor. Therefore we are going to confirm the effectiveness of retinoic acid to inhibit the proliferation of the tumor cells; glioblastoma and medulloblastoma in childhood. METHODS: Medulloblastoma cells were derived from the primary culture of the patient's specimen, and glioblastoma cells were cell lines of 373-MG and 87-MG. We estimated growth inhibition rate of each tumor cells using MTT assay in the concentration from 10 M to 10((-5))M of all-trans and 13-cis retinoic acid. RESULTS: 13-cis retinoic acid in the concentration of 10 6M inhibited cell growth rate 10-22% on the 4th day of incubation, 10% on the 7th day, and 0-12% on the 14th day in the concentration from 10((-6))M to 10((-5))M. All-trans retinoic acid inhibited cell growth rate less than 5% in the concentration less than 10((-5))M though the whole incubation period, but 42% on the 4th day, 37% on the 7th day, and 0% on the 14th day in the concentration of 10((-5))M. 13-cis retinoic acid inhibited cell growth rate 30% on the 4th day, 20% on the 7th and 14th day in the concentration between 10((-6))M and 10((-5))M. Alltrans retinoic acid inhibited cell growth rate less than 5% on the 4th and 7th day. Medulloblastoma cells showed growth inhibition more than 25% by all-trans and 13-cis retinoic acid in the concentration less than 10((-6))M. 13-cis retinoic acid showed 25% growth inhibition in the concentration above 10((-6))M, but all-trans retinoic acid showed 40% growht inhibition in the same concentration. CONCLUSION: We could not find the effect of retinoic acid in the glioblastoma cells due to variable responses of the tumor cell growth inhibition in the concentration of maximum tolerable dose. However, there ia a significant inhibitory effect of medulloblastoma cell proliferation both in the 13-cis and all-trans retinoic acid.
