OBJECTIVE: To verify the effect of Matrigel, a ECM complex from Engelbreth-Holm-Swarm(EHS) mouse sarcoma on the preimplantation development and apoptosis of mouse fertilized eggs. METHOD: Late Pronucleus stage eggs were cultured through the blastocyst stage in the presence of Matrigel (0.5%, v/v). Characteristics of apoptosis and cell number assessed by Hoecst staining and TUNEL labeling at the blastocyst stage, respectively. RESULTS: Morphological development, number of cells per embryo was significantly increased but rate and number of TUNEL positive nuclei of the embryo were decreased in the presence of Matrigel. CONCLUSION: This result suggested that at low concentration of Matrigel improves both viability and morphological development in the preimplantation mouse embryos.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

Leiomyomas of vagina and vulva are rare solid tumors, but most common mesenchymal tumors in adult woman. Most of the reported cases have been benign. The tumors were firm, well-defined submucosal masses in a majority of patients. We experienced two cases of vulvar and vaginal leiomyoma, thus it is presented with a brief review of the cases and its literatures.

OBJECTIVE Present study was aimed to verify the effect of granulocyte macrophage-colony stimulating factor (GM-CSF) in the preimplantation development of mouse embryos and the involvement of the mitogen activated protein kiase (MAPK) in the GM-CSF signaling. METHODS: Two-cell embryos were cultured for 96 h in the presence or absence of GM-CSF (0, 0.4, 2, 10 ng/ml) and PD98059, a MEK inhibitor (10 muM). Morphological development, cell number per blastocyst, and apoptotic nuclei, were eamined. MAPK activity of embryonic immunoprecipitate by MAPK (ERK1/2) antibody was measured by in vitro phosphorylation of myelin basic protein. RESULTS: At post hCG 122 h the embryonic development among the experimental groups was significantly different (p=0.018). The rate of blastocyst development and cell number per embryo were the highest in 2 ng/ml GM-CSF treatment group. The percent of apoptotic cells of the GM-CSF-treated embryos was the lowest among the group. in blastocysts, GM-CSF treatment transiently increased MAPK activity. PD098059 attenuated the effect of GM-CSF on the morphological development, increase in cell number per blastocyst, down regulation of apoptosis, and upregulation of MAPK activity, suggesting that activation of MAPK cascade possibly mediated the embryotropic effect of GM-CSF. CONCLUSION: This result suggested that GM-CSF potentiated the development of preimplantation mouse embryos by activation of MAPK.
