The first mouse's uterus transfer operation in the world succeeds
It is reported according to October 22 of Britain " The Times ", a world unites the medical group to say, they have carried on global first example palace transfer operation on mouse successfully. In the course of transplanting, blood pressure of mouse very steady, accept mouse that uterus transplant survive 10 long month, have increased its pregnant probability greatly. Researchers may carry on the uterus in two years in the human body on one's body to transplant the experiment, this will be some unable pregnant women's good news.

Doctor, veterinarian, New York, U.S.A. and medical group of Budapest, Hungary of London have carried on this experiment together. The leader, lying in the gynecological expert of the hospital of Chinese silent Smith of London Richard and Smith of this group says, they have already solved the uterus and transplanted in the course " The obstacle " --Transplant the stability how course keeps blood pressure, in order to accept the surviving time of the mouse transplanted is longer, increase its pregnant chance.

It is transplantation technology of uterus that the blood which keep steady has been supplied all the time " The obstacle " . In 2000, scientists carried on the palace transfer operation of an example on one women 26 -year-old Saudi Arabia, because the blood vessel which supplies the oxygen stops up, the operation ends in failure finally, the scientist has carried on the uterus transfer operation on pig, sheep and monkey too, animal these because blood clotting or excessive dying. If has broken through this question, it may be safer to carry on the uterus transfer operation on mankind.

The latest experiment is that the royal beast's medical college in London carried on in Britain. In the experiment, scientists have used 10 mice, among them 5 donate the uterus, other 5 accept the uterus. The scientist has used on mouse who accepted uterus " The patch technology of blood vessel " (the main blood vessel including aorta of this technology is linked together to let blood pressure remain stable) .

In 5 mice accepting the uterus is transplanted, there is life-span of two mice that exceeds 10 months. Scientist go on, check, find to other mouse that die his death reason has no relations with transplanting, this indicates uterus transfer operation has succeeded. Smith says, though has mated to the mouse surviving, it is pregnant that they have not succeeded either, the scientist hopes to make the mouse become pregnant by letting the embryo fertilized in the laboratory in further research.

The scientist expresses, the women who has accepted uterus transfer operation must accept test tube baby's treatment to be pregnant, and in order to avoid complication, should adopt the caesarean birth to bear children.

The doctor of New York has already been permitted carrying on the experiment on mankind, before this, they have already proved the donor's uterus can be kept for more than 12 hours, this time is used for doing the operation more than sufficiently.

But this experiment has initiated some disputes. Britain bear Tony of association president SeFu Luo say, succeed in and apply old animal to and there is difference greatly between the mankind on mouse.

It is reported independent charity Britain uterus transplant and organize offering the subsidy of 250,000 pounds to this research group.
