OBJECTIVE: There is a large and increasing body of experimental and clinical data supporting the existence of variable estrogen receptors in both normal and neoplastic estrogen target tissue. Recently, exon 5 deleted estrogen receptor(D5-ER) has been identified in many estrogen dependent tumors. The purpose of this study is to assess the relationship between uterine myoma and D5-ER. METHODS: The relative amount of wild type estrogen receptor mRNA and D5-ER mRNA were examined in human myometrium and myoma tissue obtained from 12 myoma patients and 12 control subjects by RT-PCR. The correlation between WT/D5-ER ratio and age was also evaluated. RESULTS: There was no difference in expression of D5-ER mRNA not only between myoma and myometrim of the myoma patients, but also between myometrium of myoma patients and normal subjects. No significant correlation was found between D5-ER expression and age of the subjects in myometrial tissue. However, we could find negative correlation between WT/D5-ER ratio and age in myoma tissue. CONCLUSION: Upon these data, we conclude that D5-ER is a common variant mutation of estrogen receptor, which is not related with development of myoma. However, in myoma tissue, there is possibility that D5-ER may act some role in the growth of tumor.

130 cases of the suprarcondylar fractures of the humerus in children were analysed. 60 cases were immobilized with plaster splint without closed reduction. 22 cases were closedly reduced and immobilized with plaster splint. 47 cases were closedly reduced and were fixed percutaneously with K-wires. 39 cases were operatively reduced and were fixed with K-wires. The following results were obtained. 1. The average age was 7.9 years, and the male and female ratio was 2.7: 1. 2. The extension type was 96.2% and the flexion type was 3.8%. 3. The left side (64.6%) was more frequently involved. 4. As associated complications, nerve injury (4.6%), vascular injury (2.3%), open fracture (2.3%), and associated fracture (2.3%). were developed. During treatment incomplete ulnar nerve palsy (2.3%), pin tract superficial infection(3.1%), severe cubitus varus deformity(4.6%), severe limitation of elbow motion(11.6%) were also developed. 5. Final results in the Holmberg's 4 Groups according to Mitchell & Adams' criteria showed that the more the displacement of fracture is increased, the more the poor result is also increased. 6. In spite of the selection of the more severe cases for surgery, the results of the operative cases were better than those achieved by closed reduction in the easier cases. 7. In the displaced fractures, immediate open reduction brings the satisfactory results and minimizies the sequellae.

Thanatophoric dysplasia (TD) is a sporadic lethal type of skeletal dysplasia featuring micromelia, decreased thoracic dimension and macrocephaly. To date, several kinds of mutation in fibroblast growth factor receptor 3 (FGFR3) has been identified in TD. We experienced a case of TD type I and underwent sequencing of the exon 7, 10 and the stop codon of FGFR3 to identify the type of mutation. TDI was diagnosed by the prenatal ultrasound at 25 weeks of gestation. The pregnancy was terminated and the diagnosis was confirmed by radiological and histologic examinations. The genomic DNA was extracted and the sequences of the exon 7, 10 and the stop codon of FGFR3 were amplified by PCR. The sequencing was performed for the each PCR products by dideoxyterminator method. The nucleotide transition from G to T was found in the nucleotide 1108, which is a part of the transmembrane domain, exon 10. To date, only one type of mutation (nucleotide 742) in the FGFR3 was identified in TD1 among Asian. This case firstly reveals the mutation of FGFR3 other than mutation at nucleotide 742 in TD1.

OBJECTIVE: The present study was performed to investigate the efficiency of partial laser assisted hatching (p-LAH; lased 1/2 ZP width from ZP edge) on hatching of mouse blastocysts. METHODS: We used non-contact 1.48 micrometer diode laser (MTM, Switzland) to create a precise hole on zona pellucida. 2-cell embryos were collected from the mouse (ICR) oviduct at 48 hours after hCG administration. Collected 2-cell embryos were cultured in the P-1 medium supplemented with 0.4% BSA. For experiments, embryos at 8-cell stage were used after 20~22 hours in culture. After conventional (c-LAH) or partial laser assisted hatching, the embryos were further cultured in P-1 medium supplemented with 0.4% BSA for 3 days. To compare efficiency of complete and partial laser assisted hatching, hatching rate, hatching time and blastocyst diameter and zona pellucida thickness at hatching time were investigated. Embryos were examined every 12 hours. Blastocyst diameter and zona pellucida thickness at hatching time were measured with an ocular micrometer. RESULTS: Hatching rates of p-LAH group (84.2%) was significantly higher than that of control group (39.3%), but there was no difference between the p-LAH (84.2%) and c-LAH (91.2%). p-LAH group was hatched 12 hours earlier than control group, but hatched 12 hours later than c-LAH group. The diameter of blastocyst at hatching time of p-LAH group (113.1+/-6.4 micrometer) was smaller than that of control group (122.2+/-5.0 micrometer), but larger than that of c-LAH group (102.2+/-2.7 micrometer). Zona pellucida thickness at hatching time of p-LAH group (6.4+/-0.9 micrometer) was thicker than that of control group (4.5+/-1.5 micrometer), but thinner than that of c-LAH group (10.0+/-0.8 micrometer). CONCLUSION: These results suggest that p-LAH may maintains the cell arrangement of early embryos to ensure successful development and prevent precocious hatching of blastocyst when compare to c-LAH and conventional (acidic tyrode) AH. Thus, p-LAH may provide a valuable and effective AH technique for human ART program.

OBJECTIVE: The purpose of the current series of experiments were to assess the effect of GM-CSF, as a medium supplement, on the development of mouse embryos and the expression of LIF and IL-1beta mRNA. MATERIALS AND METHODS: Mouse 2-cell embryos were collected from the oviducts of 6 weeks old ICR mice at 48 hours after hCG injection. Embryos were cultured in P-1 medium supplemented with mouse GM-CSF(0,1,5,10 ng/ml). The embryo development to blastocysts and hatching blastocysts was assessed and the cell number in blastocyst was also examined. Using RT-PCR, the expressions of LIF and IL-1beta mRNA in blastocyst were evaluated in the GM-CSF supplemented group and control group. RESULTS: In mouse, the addition of GM-CSF increased the percentage of blastocysts(65.5%, 68.6%, 73.0% and 76.1% for control and 1, 5 and 10 ng/ml, respectively), and increased the proportion of hatching blastocysts(35.2%, 36.4%, 43.2% and 53.0% for control and 1, 5 and 10 ng/ml, respectively). The mean cell numbers in blastocyst were significantly increased in GM-CSF supplemented groups compared to control group. LIF and IL-1beta expression in blastocysts were significantly higher in GM-CSF supplemented group than in control group. CONCLUSION: The results of experiment by mouse embryos showed beneficial effects of GM-CSF as a medium supplement. Furthermore, the addition of GM-CSF significantly increased the expression of LIF and IL-1beta in mouse embryos. These results suggest that GM-CSF might be a important molecule in embryo implantation.

Dieulafoy lesion is very small and easily overlooked as a course of massive, often recurrent hemorrhage that results from the crosion of a submucosal artery, typically in the gastric cardia or fundus. The clinical picture of Dieulafoy lesion is quite uniform: patients commonly present with massive hemorrhage and melena without any relevant history. The diagnostic procedure of choice in patients with severe gastrointestinal bleeding is emergency endoscopy. The lesion is rare but potentially life threatening source of upper gastrointestinal bleeding. Before the endoscopic era, the prognosis for patients with these lesions was quite poor. However, recent reports have described the success of endoscopic therapy in the management of Dieulafoy lesion. We performed emergency endoscopy in 3 patients who had massive or recurrent episode of upper gastrointestinal bleeding, identified to the Dieulafoy lesion. We tried to Endoscopic "0" band ligation, successfully in hemostasis and prevention of recurrence.

Endoscopic injection sclerotherapy(EIS) has been shown to be the most effective simple method for control of bleeding and eradication of varices. This method has been aceepted widely as a standard treatment of bleeding esophageal varices. However, EIS may be associated with undesirable local and systemic complications. (continue...)
