OBJECTIVE: The study was performed to compare the survival rate and the development of day 2 mouse embryos which had freezing procedures done. METHODS: We used three different vitrification solutions (EFS, VS14, DPS) and a ultrarapid freezing solution (UFS) for cryopreservation of day 2 mouse embryo. RESULTS: We tested toxicity by exposing embryos to vitrification solutions and a ultrarapid freezing solution. The survival rates are 100%, 97.8%, 95.6% and 100% (EFS, VS14, DPS and UFS). After cultured for 96 hours, hatching rates of each group are 93.5% (no freezing), 95.6% (EFS), 86.4% (VS14), 93.0% (DPS), and 93.0% (UFS). There is no significant differences among groups. The survival rates after thawing cryopreserved embryos are 80.2%, 91.7%, 69.5%, 0% and 91.8% (slow freezing, EFS, VS14, DPS and UFS). Also cultured for 96 hours, the hatching rates are 93.5% (no freezing), 84.1% (slow freezing), 93.9%) (EFS), 48.5% (VS14) and 70.1% (UFS). CONCLUSION:The survival rates of vitrification in EFS solution and ultrarapid freezing are higher than slow freezing (p<0.05). The hatching rate of vitrification in EFS solution cultured for 96 hours is highest, so vitrification of day 2 mouse embryos in EFS solution considered as more effective for cryopreservation.

BACKGROUND: Afterload as well as myocardial contractil ity is an important factor for the adequacy of circulation after cardiac surgery . To noninvasively assess alterations in afterload, we evaluated the changes in aortic blood velocity waveform. MATERIAL AND METHOD: Ascending aortic blood flow was measured by continuous wave Doppler echocardiography befo re and after afterload manipulation in eight open-chest dogs. Nitroprusside was administered singly and simultaneously with epinephrine in various combinations. Left atrial pressure as an index of preload was maintained by saline administra tion. RESULT: The infusion of nitrop russide produced dose-dependent decreases in blood pressure and index of systemi c vascular resistance(ISVR) (all p<0.05 vs baseline), which was associated with increases in peak velocity(PV), mean acceleration(MA) and minute distance, and w ith a decrease in acceleration time(all p<0.05 vs baseline). ISVR obtained durin g nitroprusside infusion had a better correlation with both PV(r=-0.60, p=0.001) and MA(r=-0.52, p=0.003) than with velocity time integral(VTI) or the Doppler t ime intervals. The combined infusion of nitroprusside and epinephrine, unless IS VR was elevated, produced synergistic effects on PV, MA and VTI, but these Doppl er indexes tended to diminish with an elevation in afterload. CONCLUSION: Doppler measuremen t of PV and MA in the ascending aorta may be used to noninvasively assess change s in afterload.

PURPOSE: This study was done to evaluate the effects of the peer suicide prevention gatekeeper program for use with middle school students. METHODS: The research design was a quasi-experimental research of a nonequivalent control group. The gatekeeper program was used as the experimental treatment with the students from May 14 to June 11, 2010. The 54 research participants were assigned to the experimental (23) or control (31) group. The gatekeeper program was administered four times to the experimental group. Data analysis was done with SPSS 12.0 for t-test and ANCOVA. RESULTS: There were significant changes in the level of problem solving competence. There were no significant changes in the level of depression, and suicidal ideation. CONCLUSION: These results indicate that the Gatekeeper program is an effective nursing intervention to increase the level of problem solving competence in middle school students.

Nevus comedonicus is a rare skin abnormality characterized by a unilateral and usually linear distribution of groups of comedones, Histologically, local epidermal invagination and keratin material plugging in invaginated pouch and immatured hair follicles on lower part of the pouch were seen. Two cases are reported at first in the Korean literature. Case 1: A 24 year old man has had black colored comedolike skin lesions on left cheek with 16 years duration without any subjective symptoms. Case 2: A 19 year old girl has had multiple comedolike lesions on right buttock with 2 years duration, acompanied by recurrent suppuration and moderate itching. Our 2 cases, all are typical Nevus Comedonicus Unilateralis case in clinically and histopathologically. Treatment with local application of steroid cream and dermoabrasion resulted good effect, but essentially there is no need to treat untill complication deveoped.

PURPOSE: The purpose of this study was to examine risk factors for sexual behaviors in Korean female high school students. METHOD: Data was collected by a written questionnaire from June 22 to July 18, 2002 from 522 girls, who were stratified samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul, Korea. We conducted multiple regression analysis using the SAS pc+ program. RESULT: Risk factors for intimate behaviors were association with boy friends, differential association, family attachment, and family abuse experience. These variables cause 68% of intimate behaviors. Risk factors for sexual experiences were differential association, association with boy friend, and family attachment. These variables cause 14% of sexual experiences. CONCLUSION: Efforts to reduce sexual behaviors in girls should include the possible role of peers and develop peer leader programs.

A 52-year-old woman was admitted with a palpable mass on the abdominal wall. This tumor had developed at the same site of a previously resected dermatofibrosarcoma protuberans. The biopsy specimen from the recurrent tumor revealed malignant fibrous histiocytoma. Immunohistochemistry with anti-CD34 antibody revealed diffuse linear positivity on the tumor cells of dermatofibrosarcoma protuberans and negativity on malignant fibrous histiocytoma. Anti CD34 antibody was valuable for a differential diagnosis of these two lesions.

Adenoid cystic carcinoma (ACC) of the breast is an uncommon carcinoma accounting for less than 1% of the breast carcinoma. This type of carcinoma has a distinctive histology, such as cylindromatous, cribriform, glandlike space and solid pattern in the variable proportion. Prognosis is favorable with rare recurrence or metastasis and the guideline for therapy is not well established. We experienced a case of ACC of right breast in the 48 year-old woman. Cytologically, it showed numerous three-dimensional, well outlined cell clusters with central core of homogeneous, eosinophilic material. The mass was well demarcated, firm and measured 2.5 2.5 2 cm. Cut surface was yellowish white and granular with focal necrosis. Histologically, the tumor was composed of cylindromatous, adenoid and solid area with marked cellular atypia. Focal invasion was identified in the adipose tissue around the tumor. Histologic and nuclear grade was III by Kleer's grade. Nodal metastasis was not found.
