1.Two treatment approach to skeletal Class III : A case report on sisters.
Korean Journal of Orthodontics 1999;29(3):327-337
Patients with skeletal class III can be successfully treated by either orthognathic surgery or orthodontic treatment owing to unavoidable circumstances. Sisters were treated, elder sister by orthognathic surgery and younger one by compromised treatment. For the ideal treatment goal, orthognathic surgery will be inevitable in skeletal problem case, but by the patient`s private situations orthodontist cannot help doing compromised treatment. It could be another option if correct biomechanical approach is used.

Objectives: This study was to evaluate whether Ham's F-10 used in assisted reproductive technology (ART) could be replaced with newly-introduced Medicult or Human Tubal Fluid (HTF) media, and the rate of embryo development could be enhanced by cumulus cell coculture. METHODS: Ham's F-10, Medicult, and HTF media supplemented with 0.4% bovine serum albumin (BSA) were used. Two-cell embryos were obtained from oviducts of mated F1 hybrid female mice superovulated by pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG). Cumulus cells for coculture were obtained from oviducts of ICR female mice superovulated by PMSG and hCG. Two-cell embryos were cultured in Ham's F-10, Medicult, and HTF media respectively to observe and compare the rate of embryo development. In addition, two-cell embryos were cultured in these three media for 24, 48, 72, 96 hrs with or without cumulus cell, and rates of embryo development were investigated and compared. RESULTS: As for the rate of embryo development to hatched blastocyst after 96 hrs culture, HTF (87.5%) and Ham's F-10 (85%) were significantly higher than Medicult (70.5%). The beneficial effect of embryo development by cumulus cell coculture on two-cell mouse embryo among these three media was enhanced significantly in Medicult (control 88.5% versus coculture 98.5%) by 24 hrs, and was not enhanced statistical significantly but slightly elevated in Ham's F-10 (86.5% versus 95.5%) and HTF (91.3% versus 96.9%) by 48 hrs, but rates of embryo development were similar between control and coculture group in all three media by 96 hrs. Significant differences were not shown in three media, but HTF showed generally high tendency of the enhancing effect of embryo development and the beneficial effect of embryo development by coculture. CONCLUSIONS: As a result of culturing two-cell embryos in three media for 96 hrs, generally HTF and Ham's F-10 showed higher rate of embryo development than Medicult. As for the beneficial effect of coculture, Medicult only showed early transient significant improvement of embryo development. Considering that coculture effect of good quality media may be not so great, Ham's F-10 and HTF are more stable media than Medicult. Accordingly, HTF may be considered to be a medium to replace with Ham's F-10, however, the present study suggest that Medicult or HTF is not able to replace with Ham's F-10 in ART.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

Three cases of sclerosing stromal tumor of the ovary are presented. All three patients were nulliparous young wemen of 23~25 years of age, presenting with menstrual irregularity for 6 months to 4 years. Grossly the tumors ranged in size from 8 to 22cm in greatest diameter, showing gray white to yellow solid or predominantly cystic tissue with serous fluid. The common microscopic finding was that of cellular areas admixed with densel fibrous and/or edematous tissue, presenting pseudolobular appearance. Two types of tumor cells were rounded cells with clear vacuolated cytoplasm and less numerous spindle shaped cells. Postoperative course was uneventful and menstrual irregularity disappeared postoperatively. In case 2, the patient got pregnant after 1 year and 4 months. This clinical course suggests that sclerosing stromal tumor of the ovary may be endocrinologically active.

OBJECTIVES: This study was to investigate the fertilization rate after intracytoplasmic sperm injection (ICSI) or partial zona dissection (PZD) of human and hamster sperm into hamster oocyte in in vitro fertilization (IVF). In addition, the possibility of clinical application was evaluated by the comparison of usefulness and difference of these method. MATERIALS AND METHODS: Hamster immature oocytes were obtained from oviducts superovulated by PMSG and hCG, and hamster sperms were obtained from epididymis. The freezed human sperms were thawed before use. Fertilization were confirmed by two pronuclei, one pronucleus, swollen sperm head or/and two polar bodies at 7~8 hour after ICSI or PZD. RESULTS: The fertilization rates after ICSI and PZD of human sperm to hamster oocyte were 3.6%, 64.2%, 73.6%, and 55.6% for negative control, positive control, ICSI, and PZD respectively, suggesting that ICSI only showed improved fertilization rate (p<0.01). The fertilization rates after ICSI and PZD of hamster sperm to hamster oocyte were 11.1%, 51.2%, 39.6%, and 72.7% for negative control, positive control, ICSI, and PZD respectively, suggesting that PZD only showed improved fertilization rate (p<0.01). PZD showed significantly higher fertilization rate than ICSI (p<0.05). CONCLUSIONS: As for the fertilization rate by ICSI and PZD using hamster oocyte in IVF, ICSI technique was considered to be more useful for human sperm and PZD technique for hamster sperm. Therefore, ICSI technique was considered more appropriate for experimental application using human sperm and hamster oocyte.
