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.

The ligamentum nuchae is a midline structure extending from the occiput to the spinous process of the 7th cervical vertebra. Radio-opaque formations in the soft tissues behind the processes of the cervical spine has been known to radiologists since Barsony's description in 1929. It may actually be a normal sesamoid, or it may have developed as a result of previous trauma. But this remains hypothetical in that histological endochondral ossification sequence has not yet been demonstrated. These are generally asymptomatic and of clinical significance only in so far as they may be confused with fracture or tumors. Two patients who had clinical symptoms with or without previous trauma visited and they were relieved of their clinical symptoms by surgical excision. Then, we report on two unusual cases which were symptomatic.

The Morel-Lavallée lesion (MLL) is a closed soft-tissue degloving injury, resulting in characteristic hemo-lymphatic fluid collection between the fascia and subcutaneous layers. The MLL was managed routinely with drainage and compression bandages, but sclerotherapy can be used in patients with chronic lesions refractory to first-line therapy. This paper presents a case of extensive recurrent chronic MLL treated with sclerotherapy using Abnobaviscum, which has been used to treat adhesion in malignant pleural effusion.

In the past two decades, the incidence of rubella infection has decreased due to a nation-wide rubella vaccination program. Therefore the rate of rubella Ig G antibody has decreased. This means an increasing vulnerability to rubella infection among the group, with negative Ig G antibodies. The study was conducted in January of 1992 to April of 1996. The subjects were 1,010 fertile women(ages 20/45 years). The study was performed at Park Women`s Clinic to investigate the status of rubella antibody in Korean fertile women. The results were as follows. 1. The positive rate of rubella Ig G and Ig M antibody were 80.5% and 1.5%, respectively. 2. The mean age of positive rubella Ig G group was 28.5+/-3.6 years. The positive rate of rubella Ig G antibody was decreased by an increase in age with a significant level at p < 0.05. 3. The positive rate of rubella Ig G antibody was 63.3% in 1992, 71.3% in 1993, 87.5% in 1994, 81.1% in 1995 and 83.8% in 1996. The increase in the positive rate of rubella Ig G antibody by year for 5 years was statistically significant at p < 0.05. 4. The positive rubella Ig M antibody was noted in 15 women. Among them, one woman was tested in 1993, 5 women in 1995 and 9 women in 1996. The incidence of rubella infection had increased by years, and was statistically significant at p < 0.05. 5. The mean titer of rubella Ig G antibody was 47.18+/-50.04 IU/ml. The titer of rubella Ig G antibody was decreased by the increased in at age(p < 0.05). We observed a low positive rate of rubella Ig G antibody as compaired with other studies that were performed before 1990. Therefore, to prevent sporadic rubella infections, rubella vaccinations should be given to unmarried women.

Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.
