Squamous cell carcinoma (SCC) of the cervix with intraepithelial extension to the endometrium is a rare event, accounting for about 0.7% of all cervical SCC. Endometrial lesion has been considered as a direct extension of cervical cancer in the early reports, and this was confirmed in a recent molecular study. I report here on the case of a 56-year-old woman who had stage IIB SCC of the cervix with extension, in an in situ fashion, to the entire endometrium. HPV type 16 was detected via PCR in both the cervical and endometrial tumors.

Organ transplantations have become popular procedures for diseases in modern medical field with developing medical science. There have been so many hot discussions about ethical issues of organ transplantation, especially brain death, whenever medical ethics was addressed. However, we have not so far discussed ethical issues related to tissue banking, even though the history of tissue banking in medicine is longer than that of organ transplantation and the range of use of Human-based tissues is wider than that of organ transplantation. Tissue banking has medically and ethically similar aspects with organ transplantation, but tissue banking system has unique characteristics in total process. Ethical questions related to tissue banking involve informed consent, conflicts of interest, and the equitable distribution of human-based tissues and related profit issues. Families expect that their beloved ones' tissue will be used to improve the lives of people with medical needs, either through transplantation or medical research. However, concerns have been raised that some tissue might be used for purpose other than those intended by the donor. Donors may intend or believe that donated skin shall be used for the treatment of burn victims. However, in some cases it might be used for elective cosmetic surgery. It is not clear how much human-based tissues are currently used for cosmetic purposes, but there is always a potential commercial application of human-based tissues. The question is whether this is morally acceptable. We should always honor and treat with respect to the donors' wishes, and distribute the human-based tissues maximizing its usefulness and minimizing its hazards and waste the tissue.

The human semen ejaculated in a form of liquid state, coagulates immediately after ejaculation, and then liquefies again. However, the mechanisms of neither coagulation and liquefaction of semen have not been explained clearly so far, and very limited numbers of report are available, although the spermatology and andrology made rapid progress. This clinical study has been undertaken to investigate the liquefaction phenomena and practicability of the results might be applied to fertility and infertility problems. As a preliminary study, in this report the liquefaction time of various semen groups is measured and analyzed. The following results are obtained: 1. An average liquefaction time of semen of a total of 60 subjects:25 minutes. 2. An average liquefaction time of semen according to sperm count: I) Normospermia group(20 cases) :34 minutes. 2) Oligospermia group(20 cases) :21 minutes. 3) Azoospermia group(20 cases) :20 minutes. An average liquefaction time of semen according to abstinence period: I) Less than 3 days group(20 cases) :22 minutes. 2) More then 5 days group(30 cases) :28 minutes. In conclusion: I. The liquefaction time of semen of the normospermia group is longer than oligospermia group or azoosermia group. 2. The liquefaction time of semen may not be greatly influenced by the various factors such as abstinence period. semen volume, semen pH. age of the subjects and so on. In routine semen analyses, it is recommended to begin the analysis at least 25 minutes after the ejaculation. 4. Further studies are required in conjunction with practical application of liquefaction mechanism in infertility and fertility control.
