in December, 2006, the American Country Health Research institute stopped two item of masculine wrapper links cutting the technique the clinical trial, because the early data demonstrated that this process obviously reduced AIDS virus's dissemination, is published about this topic's research results in "Surgeon Lancet" the magazine. In these two items carry on stochastically in the experiment, including from is pulled measuring card Iraq, Ugandan, Kisumu and Kenya's 7780 HIV negative male, the researchers discovered that when has the sex act with the female, accepts the surgical department wrapper link to cut the technique the male not to lower at least compared to the receiver the HIV infection probability 51%. "Lancet" the editor calls this discovery it “the HIV prevention new times”. The good surgery's masculine change has not infected HIV
It is well known, AIDS's dissemination way has three kinds: The sex act disseminates, the blood dissemination and the maternal infant vertical dissemination. And disseminates through the sex act infects AIDS to account for about 80%. In the adult male, estimated that has 70% infected people are through passes through the vagina sex act to obtain, even surpasses 90% in African this proportion. Therefore the people are seeking the male diligently to AIDS's Yi Gan the factor, hoped that may reduce AIDS in the adult male dissemination probability.
Actually just started at AIDS is popular in the world, Professor Fink in 1986 proposed that cuts the technique through the masculine wrapper link to be possible to reduce AIDS's occurrence. After many year clinical researches and the laboratory research, obtained the good wrapper link not to cut the technique the male were already one which of hazard factors AIDS infects. Recent years the large-scale clinical forward-looking stochastic comparison research which carries on separately in Africa's Uganda and Kenya explicitly pointed out: The masculine wrapper link cuts the surgery to be possible obviously to reduce the African male to disseminate AIDS's risk through the opposite sex sex act, and suggested that may the technique coordinate other methods through luggage Pi Huanqie to prevent AIDS's occurrence together.
The wrapper link cuts the technique to control the HIV significance to be significant
Why does the wrapper link cut the technique to have the prevention AIDS's function? The following explanation as if may show the question: In masculine wrapper board mucous membrane after penis erection will expose, but the wrapper interior mucous membrane will include the rich HIV virus's target cell, like Langge Hans cell, cD4+T cell, macrophage and so on. In the near future has had the male which the spread disease infects, these cell's quantity can be more. But in glans and outside on skin, because has squamous cell's cover protection, the HIV virus is not easy to encroach upon the human body. Other possibility's reason is as a result of the wrapper cover glans, makes it not to be easy to obtain clean, easy to have the infection, ulcer, the sex act easy to create the wrapper and glans's friction damage, causes the HIV virus the infection.
WHO AIDS prevents and controls the department and the United Nations AIDS plan bureau official indicated that the wrapper link cuts the technique this prevention AIDS new method the confirmation to have the important meaning regarding the control AIDS spread. However, they believed that while adopts the wrapper link to cut technique this method, the men and women when carry on the sex act certainly must continue to use other guard method, for instance use condom and so on.
