The present study was to assess the effect of ultrarapid freezing on the development of 1-cell mouse zygote using cryoprotectants, DMSO (dimethyl sulfoxide) or PROH (1,2-propanediol). We investigated the effect of the type and concentration of cryoprotectant, and of the temperature and time of prefreezing equilibration on their capacity to develop to the blastocyst stage in vitro. The concenration, the equilibration temperature, and the exposure time seemed to serve as an important factor in ultrarapid freezing of 1-cell mouse zygotes. In addition to the exposure time and the concentration of cryoprotectant appeared to play a key role in the development of the embryo. In general, the development of the embryo was more effective at 3degrees C than 23degrees C and 4.5 M than 3 M for 3 to 5 minutes. At 23degrees C the development of the embryo was stimulated by DMSO while at 3degrees C it was stimulated by PROH. Thus it has been suggested that there exists a correlation between the concentration of cryoprotectants and exposure time in the development of the embryo. In conclusion, we found that for ultrarapid freezing of mouse 1-cell embryos in DMSO, or PROH-based solution, viability shown optimum depending on the cryoprotectant, the concentration of the cryoprotectant and on the temperature and the duration of equilibration.

Although fungal infections involving the genitourinary system are increasing in case, those involving the prostate are uncommon and fungal prostatic abscesses are especially rare. There are a few sporadic reports in the literature of fungal prostatic abscess. We thought that a high index of suspicion for fungal prostatic infection must be maintained especially in high risk patients. We report a case of candidal prostatic abscess in a 37-year old man with diabetes. The diagnosis and management are discussed, and the literature is reviewed.

Leiomyoma is a benign tumor, which usually occur at the smooth muscle of the gastrointestinal tract and uterus but rarely occurs on the corpus cavernosum of the penis. We experienced a patient with leiomyomas on the bilateral corpus cavernosa of the penis accompanied with impotence in a 60-year-old man. The patient was treated with complete local excision and has remained well without recurrence for l year, So we report this case with review of literatures.

PURPOSE: Traditional anterior colporrhaphy repair can have a high recurrence rate. Therefore, the use of synthetic mesh to reinforce the anterior vaginal wall support has been proposed to prevent recurrence. The objective of our study was to compare the anatomic recurrence rates in patients that underwent the traditional anterior colporrhaphy with patients who add a monofilament polypropylene mesh repair(Gynemesh PSTM). MATERIALS AND METHODS: We reviewed the charts of patients who underwent transvaginal cystocele repair between January 2003 and June 2006. All patients had a physical examination and staging of the prolapse; the International Continence Society(ICS) system was used for the staging. Mid urethral sling operations were performed when stress incontinences was an associated feature. An anatomic recurrence was defined as an ICS stage 2 or greater anterior prolapse on the last recorded physical examination. The subjective patient satisfaction was also recorded. RESULTS: Seventy-one patients were available for study with a mean follow- up of 18.4 months. Thirty-eight patients underwent traditional anterior colporrhaphy, while 33 patients underwent cystocele repair using the monofilament polypropylene mesh(Gynemesh PSTM). Among the 71 patients, 9(12.7%) had recurrence of the cystocele. Based on the type of repair, 21.1%(8/38) of the patients with traditional repair had a recurrence compared to 3.0%(1/33) of the patients with the polypropylene mesh repair(p=0.03). With regard to satisfaction, 76.3%(29/38) of the patients with anterior colporrhaphy and 97.0%(32/33) with the mesh repair were satisfied with the outcome of the surgery(p=0.02). One patient had erosion of the mesh, at the midline, in front of the vaginal scar, at 12 months after the procedure. CONCLUSIONS: Our results suggest that the monofilament polypropylene mesh(Gynemesh PSTM) repairs improved the outcomes of anterior colporrhaphy with regard to the prevention of recurrent cystoceles.

Growth factor stimulation induces Y783 phosphorylation of phosphoinositide-specific PLC-gamma1, and the subsequent activation of this enzyme in a cellular signaling cascade. Previously, we showed that a double point mutation, Y509A/F510A, of PLC-gamma1, abolished interactions with translational elongation factor 1-alpha. Here, we report that the Y509A/F510A mutant PLC-gamma1 displayed extremely high levels of Y783 phosphorylation and enhanced catalytic activity, compared to wild-type PLC-gamma1, upon treatment of COS7 cells with EGF. In quiescent COS7 cells, the Y509A/F510A mutant PLC-gamma1 exhibited a constitutive hydrolytic activity, whereas the wild-type counterpart displayed a basal level of activity. Upon treatment of COS7 cells with EGF, the Y783F mutation in Y509A/F510A PLC-gamma1 (Y509A/F510A/Y783F triple mutant) cells also led to an enhanced catalytic activity, whereas Y783F mutation alone displayed a basal level of activity. Our results collectively suggest that the Y509A/F510A mutant is more susceptible to receptor tyrosine kinase-induced Y783 phosphorylation than is wild-type PLC-gamma1, but no longer requires Y783 phosphorylation step for the Y509A/F510A mutant PLC-gamma1 activation in vivo.

Neuroendocrine neoplasm of the larynx is a morphologically heterogeneous group of tumors. This unusual neoplasm includes the four different type of tumors. Paraganglioma is the best-known neural origin tumor. The epithelial origin tumor is further divided based on the degree of differentiation into well, moderately, and poorly differentiated carcinoma. The diverse biological behavior of neuroendocrine neoplasm of larynx makes an accurate diagnosis of paramount importance, since treatment depends on diagnostic accuracy. The diagnosis is based primarily on light microscopy, and immunohistochemical and/or ultrastructural investigations are needed to diagnose correctly. The mainstay of treatment of moderately differentiated neuroendocrine carcinoma of the larynx is surgery. Elective neck treatment should be performed considering the high likelihood of cervical lymph node metastases. The 5-yr survival rate approximates 50%, and 10-yr survival rate is only 30%.

Angiomyxolipoma is a rare variant of lipoma, which is described by Mai, 1996, at first. The nine cases of which have been reported to date. Microscopically, the lesion consists of adipose tissue with the paucicellular myxoid areas and fat tissue with numerous thin, dilated, and congestive blood vessels. The reported cases mostly located to the superficial layer on the scalp, subungual, extremities in adults. We report one case of angiomyxolipoma located in the submuscular and parosteal area in the distal femur around knee joint in a child.
