Previous applications of laser bone and cartilage ablation have focused largely on the CO2 and the Nd:Yag lasers, using both the continuous wave and rapid superpulsed mode, which revealed severe thermal damage such as tissue necrosis and carbonization of the remaining tissue. In contrast, Excimer lases have provided better histologic results with minimal or no thermal damage, but the ablation rate and cutting efficiency have remained unsatisfactory. Though arthroscopic partial menisectomy has become the accepted technique for dealing with tears in menisci, division of the meniscus is sometimes difficult in the confined joint space of the knee and is associated with iatrogenic injury to the articular cartilage. The ability to quickly and safely divide or remove meniscal tissue would be a distinct advantage. The Holmium:Yag laser has many potential advantages over the CO2 laster, the Nd:Yag laser and the Excimer laser. Its principal advantages include minimal mechanical trauma to the articular cartilage, greater access to tight or restricted area of the knee joint, and its ability to function in a saline medium and to resect meniscus with minimal tissue necrosis. We have evaluated the effectiveness of the Holmium:Yag laser 74 partial menisectomies of 57 patients. Among 74 meniscal tears, there were 35 medial and 39 lateral meniscal tears. The average operation time was 33 minutes in the menisectomy and hospital stay was average 3 days. There was no significant carbonization on the surrounding tissue. Menisectomy of the posterior horn was safe and easy and there was minimal iatrogenic articular cartilage damage.

Idiopathic thrombocytopenic purpura is an uncommon illness but most common form of thrombocytopema in pregnancy. Corticosteroids, splenectomy, immunosuppressive drugs, and immunoglobulin therapy have been recommended for manaaement. The optimal method of delivery is controversial. We have experienced a case of idiopathic thrombocytopenic purpura diagnosed previously and managed with corticosteroid and vincrstine, which was followed by pregnancy, vaginal delivery and postpiirtum splenectomy.

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.

Fibrous histiocytoma are complex group of tumors that feature cells resembling fibroblasts and histiocytes.In a case of fibrous histiocytoma involving the cornea and corneolimbus, we evaluated the finding of H-E, Masson-trichrome, reticulin, CD68, alpha-1-antitrypsin antibody and smooth muscle actin antibody stain after the localized excision in 26 years old male patient. In H-E stain, tumor cell included many multinucleated giant cells having abundant eosinophilic and foamy cytoplasm infiltreated by numerous lymphocyte, CD68 & alpha-1-antit-rypsin antibody staining resulted in diffuusely positive finding. Therefore examination. Good result was noted after complete excision at 6 month follow-up.

It is the most important to select optimal culture conditions to promote safe embryo growth in the technique of human in vitro fertilization and embryo transfer. It has been shown that the addition of biologic fluids, such as blood serum, of various origins, improved fertilization and early cleavage rates in numerous species. The purpose- of this study is to attempt to measure developmental potential of mouse eggs fertilized and cleaved in Ham's F10 culture medium containing a chelating agent, EDTA and fetal cord serum. hi this study, we selected 40 female mice and 20 male mice, and investigated optimal serum concentration' for mouse embryo growth. Two cell stage mouse embryos were cultured in Ham's F-10 medium, Ham's F-10 medium with various concentrations of EDTA, or Ham's F-10 medium with EDTA and 10% human cord serum. Developmental ratios to morula in Ham's F-10 medium containing various concentrations of EDTA and/or 10% fetal cord serum were significantly higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to blastocyst in Ham's F-10 containing 10% fetal cord serum and 5011M or 100pM EDTA were significanldy higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to morula in Ham's F-10 containing 10% fetal cord serum and 100,uM EDTA were significanitly higher than in Ham's F-10 with 10% fetal cord serum used commonly in many human IVF centers(p<0.05). Developmental ratio to blastocyst in Ham's F-10 containing 10% fetal cord serum and 100pM EDTA was significanity higher than in Ham's F-10 with 200pM EDTA(p<0.05).

BACKGROUND: It has been generally accepted that Cisapride (Prepulsid?or propulsid?), a widely used gastrointestinal prokinetic agent, is associated with Torsades de Points, a life-threatening arrhythmia. Recently, cisapride-induced APD (action potential duration)-prolongation was inhibited by glibenclamide, a KATP channel blocker. But the direct effect of cisapride on K(ATP) channels has not been studied until now. Therefore, we investigated cisapride's effects on KATP channels of isolated rat ventricular myocytes. METHODS: After the isolation of rat ventricular myocytes, we analysed the single channel current with patch pipettes. The method of analysis was the student t-test. RESULTS: 1) Cisapride (10(-6) M- 10(-4) M) inhibited KATP channel opening without changing channel conductance Ki was about 20micronM, and Hill coefficient was 0.75. 2) Cisapride inhibited pinacidil-induced KATP channel opening in the cell attached mode. CONCLUSIONS: These results suggest that cisapride-induced APD prolongation and arrythmic effects may be partly related to KATP channel inhibition.

Linear porokeratosis is a rare variant of porokerstosis and usually occurs after childhood. We report herein a case of linesr porokeratosis in an 18-year-old female. The lesions had developed since birth and were found on the nearly whole body, including the face, neck, axilla, chest, abdomen, back, and upper and lower extremities. Palms and soles were also affected. Biopsy specirnens from the left forearm and right sole showed typical cornoid lamellae. We could not see any improvement with a course of oral etretinate for 6 weeks.
