The acardius occurs with an incidence of one in 35,000 births and is presumed to result hom vascular anastomosis between the arterial circulation of the hemodynamically larger ""pump"" twin and that of the recipient ""perfused"" twin. The perfused twin displays severe anomalies, typically referred to as acardia, that are incompatible with life. The pump twin, because of its expanded cardiac demand, may also deveolp cardiac failure, with a mortality risk of 50-70%. We experienced one case of acardiac-acephalus twin gestation diagnosed by antenatal ultrasonography, and presented this.

OBJECTIVE: The objective of this study is to nfluence of sequential embryo transfers in an invitro fertilization was examined. METHOD: After in vitro fertilization, a maximum of 6 fertilized oocytes was enrolled in this study. At day 3 after an oocytes retrieval, embryos with good quality were transferred (mean 4.9), remaining embryos (mean 2.0/cycle) were cryopreserved at blastocyst stage (Group 1). At day 5 after oocytes collection, second a embryos had reached the blastocyst stage (Group 2) using P1 supplemented with 10 SSS and 30% Follicular fluid. No statistical difference in the pregnancy rate could be seen between the group without a second embryo transfer (n=21; 28.6%) and the group with a second transfer (n=52; 28.8%). RESULTS: The incidence of multiple pregnancy rate per embryo transfer was not statistically different between both group and no high-rank multiple pregnancy (greater than triplete) were observed (o.9%, 15.4%, respectively, p=0.74, chi2). Out of 114 cycles (506 embryos) cultured embryos in group 2, 52 cycles (159 embryos, 29.8%) reached the blastocyst stage. CONCLUSION: The second transfer did not have a significant effect on the pregnancy rate. The most important factor for the pregnancy seems to be the quality of the embryos transferred on day 3 following oocyte retrieval. We recommend embryo transfer is performed only one, day 2~3 or D5.

In clinical microsurgery, limitation of space often prohibits rotation of a double clamp in an end-to-end anastomosis, or shortage of length of the secondary vessel in an end-to-side anastomosis does not allow visualization of the back wall. In these situation, back wall repair is extremely difficult. To overcome this problem, we use continuous suture technique without rotation of double clamp for end-to-end and end-to-side anastomosis of the 40 rat femoral arteries. After continuous sutures for micro-arterial anastomosis, the following results were obtained: Continuous sutures are useful in anastomosis where there is unavoidable limited access to the posterior wall and for some of the larger vessels now being anastomosed in free flap and other reconstructive surgery.

Keloids are abnormally healed skin wounds that develop in the subpapillary layer of the dermis. They are a lesion with wide, raised and deep scars. They exceed the original dimensions of the wound and grow mounds upon mounds of collagen in a pseudotumor fashion. Their treatment may take several forms such as surgery, intralesional injection of steroid, compression, superficial irradiation, and combination therapy. However, absolute method is nothing until now. Recently, the cryosurgery shows relatively good effect in treatment, so we tried the clinical experience with cryosurgery in the treatment of keloids. Material and methods: During the past 2 years, we treated 20 individuals of the keloids with severe itching and pain. The age ranged from 5 to 45 years old. Only 6 cases were biopsied before and after cryotherapy. The cryosurgery set we used was Toitu model CR 201 N₂O gas (tip temperature in ­80℃) and was applied directly on the lesion about 4 to 5 minutes with slight compression. After cryosurgery in keloids, the following results were obtained: 1. It is both quick and easy method. 2. It is causes little or no pain and no loss of blood. 3. Integumentary normalization is rapid. The new scar tissue is smaller, and more elastic and soft. 4. The pain, itching and paresthesia commonly associated with keloid is usually disappeared. 5. Other treatment can be used after cryosurgery. 6. Histologic picture after cryosurgery is similar with the result of steroid injection. 7. The mechanism of the cryosurgery in keloids is the result of the direct tissue destroying action and cryoimmunologic reaction.
