Granular Cell Myoblastoma is typically encountered in the skin, subcutaneous tissue nr oral cavity, but was rarely been found in the large intestine. In a series of 110, the two were in the cecum(18). Both patients, 36-and 43-year-old women, underwent radial excision of the lesion because of the clinical impresaion of the malignancy. The other Three patients with granular cell myoblastoma of the cecum, all asymptomatic and found incidentally, have been reported. From the available data, one was a man(22) and two were women (26,27). They were 17 (27), 40(26) and 71(22) years of age. One lesion, in the cecum, was excised at laparotomy that was performed under the irnpression of acute appendicitis, and disclosed a small polypoid submucosal nodule in the cecum incidentally(27). Another lesion, in the cecum, was excised at laparotomy following the discovery of a small cecal defect on barium enema examination 9260. The other lesion, in the cecum, was found at autopsy(22), This paper reports a case of granular cell myoblastoma of the cecum, including its colonoscopic finding.

PURPOSE: The aim of this study was to evaluate the effect of dimensional stability of splinting material on the accuracy of master casts. MATERIALS AND METHODS: A stainless steel metal model with 6 implants embedded was used as a master model. Implant level impressions were made after square impression copings were splinted using 5 different techniques as follows. (1) Splinted with autopolymerizing resin and sectioned, reconnected to compensate polymerization shrinkage before the impression procedure. (2) Splinted with autopolymerizing resin just before impression procedure. (3) Primary impression made with impression plaster and secondary impression were made over with polyether impression material. (4) Splinted with impression plaster. (5) Splinted with VPS bite registration material. From master model, 5 impressions and 5 experimental casts, total 25 casts were made for each of 5 splinting methods. The distortion values of each splinting methods were measured using coordinate measuring machine, capable of recordings in the x-, y-, z-axes. A one-way analysis of variance (ANOVA) at a confidence level of 95% was used to evaluate the data and Tukey's studentized range test was used to determine significant differences between the groups. RESULTS: Group 1 showed best accuracy followed by Group 3 & 4. Group 2 and 5 showed relatively larger distortion value than other groups. No significant difference was found between group 3, 4, 5 in x-axis, group 2, 3, 4 in y-axis and group 1, 3, 4, 5 in z-axis (P<.0001). CONCLUSION: Both Splinting impression copings with autopolymerizing resin following compensation of polymerization shrinkage and splinting method with impression plaster can enhance the accuracy of master cast and impression plaster can be used simple and effective splinting material for implant impression procedure.

In this paper, two unusual cases of fetal giant lymphangiomas diagnosed before delivery is reported in 18 and 26-week pregnant woman. They were diagnosed by ultrasound. Although the cause of lymphangioma is not clearly established, they probably arise from a failure of the developing lymphatic tissue to establish normal connection with the draining lymphatics. These anomalies are most often cervical (about 70~80%) but occasionally present in the axilla (about 10%), thorax and abdomen. Lymphangioma arising at posterior nuchal region is called cystic hygroma. Lymphangioma may be divided histologically into three types ; simple, cavernous or cystic. Ultrasound examination is essential method in prenatal diagnosis of fetal lymphangioma. The differential diagnosis of these fetal lymphangioma should include meningomyelocele, benign cystic teratoma, nuchal edema, encephalocele, and subchorial placenta cyst. About 60 to 70% of lymphangioma is accompanied with chromosomal abnormalities, and most common type is Turner's symdrome (40~80%), but occasionally trisomy 21, 18, 13 and 47 XXY. But chromosomal studies of these cases showed normal findings. The 26-week fetus was IUFD at 29 gestational weeks and terminated by hysterotomy. Other 18-week fetus was terminated by vaginal delivery after intrauterine decompression.

OBJECTIVE: In vitro fertilization (IVF) and a prolonging the time of culture may be helpful in establishing a viable pregnancy through a selection effect. Some embryos do not develop beyond the 4-cell stage and some may not develop to the blastocyst stage. We have evaluated the safety of SET and the outcomes of pregnancy. METHODS: Sperms were treated with Ham's F-10 supplemented with 10% human follicular fluid (hFF). Oocytes or fertilized oocytes were cultured in Dulbecco's Modified Eagle Medium (DMEM) with 10% or 20% hFF respectively. Up to five oocytes were inseminated with approximately 200,000 sperm cells/2 ml in each well. Fertilization was examined in the following morning and fertilized oocytes were co-cultured until embryo transfer. Vero cells for co-culture were prepared in Tissue Culture Medium - 199 (TCM-199) with 10% fetal bovine serum. At the two to four cell and blastocyst on day 2 and day 5, embryo and blastocyst grading were evaluated. Pregnancy rate was determined after transfer of human embryos at the two to four cell stage on day 2 (Group I) or subsequent transfer of embryos on day 2 and at the blastocyst stage on day 5 (Group II). For statistically significant when rho value was less than 0.05. RESULTS: No differences was found in the fertilization between Group I(81.0%, 98/121) and Group II(81.8%, 180/220). In case of cleavage rate, no difference was found in Group I(95.9%, 94/98) and Group II(66.7%, 12/18) than in Group (26.3%, 5/19). CONCLUSION: The results of this study showed that SET is safe and effective, and significantly increases the pregnancy rate.

OBJECTIVE: In the preparation of ICSI, cumulus and corona cells should be removed from the oocytes by using a combination of enzymatic (hyaluronidase) and mechanical (pipetting) methods. But little is known about the effects of different degrees of oocyte denudation and incubation time between denudation and sperm injection on the outcomes of ICSI. The aim of this study was to evaluate the effects of varying the degrees of oocyte denudation and the lengths of incubation time from denudation to sperm injection on the outcomes of ICSI. METHODS: In experiment 1, patients (oocytes) were grouped into group A and B according to the degree of denudation, complete and partial, respectively. In experiment 2, patients (oocytes) were grouped into group I, II and III according to the length of incubation time of denuded oocytes until sperm injection as < 1, 1~2 and >2 hours, respectively. RESULTS: There was no significant difference between the degree of oocyte denudation on the survival, fertilization and development rates after ICSI procedure. In case of the incubation time of denuded oocytes until ICSI, survival rates was higher in group III (83.1%) than in group I (61.5%, p<0.05) or group II (64.3%). However no statistically significant differences were found between incubation time and fertilization or development rates. CONCLUSIONS: This study reveals that the outcomes of ICSI are not affected by the degree (complete or partial) of oocyte denudation. However the denuded oocytes with incubation period of more than 2 hours show better outcomes of ICSI than those with the incubation period of less than 2 hours.
