Health Care for Children

Fetus before birth in the amniotic membrane without being well protected inside, except a few micro-organisms of congenital infection can infect the fetus through the placenta, the normally sterile amniotic membrane is within the state, so the fetus during this period is the safest ; soon after birth broken water or exposed to the outside environment, began to come into contact with many micro-organisms, have the opportunity to infection diseases.

    Babies born after the crisis facing microbial infection, how to resolve? At this point the body’s immune system play an important role.

    In our gastrointestinal tract have many bacteria, bacteria can produce some useful Yifang Mian’s Substance, enhance the body’s health, on the other hand can You Jian Kang Xi Jun Ye body of the gastrointestinal tract access to a nutritious, Dadaohuhuo its profit state in which yes man and among the most perfect combination of micro-organisms. Another way is symbiotic, microorganisms in the human body made only for survival and reproduction of nutrients, and not people do not have any indication or disease, into the peace of the realm outside. The last way is parasitic, microbial nutrient in the human body in addition, it will also damage human organs must produce the disease, even death, a lose-lose situation.

Against microbial invaders

    Things foreign body with the capacity of identification, as long as their bodies will not be eliminated exclusion, which is immune. The human immune system can generally distinguish between two lines of defense, the first line of defense is on a more extensive and comprehensive, recognition ability is relatively poor but very fast start, can effectively prevent the invasion of most microorganisms, such as skin, mucous membranes, phagocytic white blood cells and complement, and so is this non-specific defense mechanisms.

    The second line of defense is usually microbial invasion, the first line of defense when abatement can not be stopped, only need to participate in the second line of defense, its ability to identify and reduce capacity, but it starts more slowly, usually a few days in order to achieve the strongest effect. Once the action will start the production memory, if the next time the same micro-organisms re-invade the body, the immune system will immediately reduce by the memory of them at once invading microbes, and thus the disease does not occur. This includes special lymphocyte immunization, and the secretion of immune substances.

Understanding of immune function

    Based on past experience found that some infectious diseases, life will only get one, will no longer suffer from the infection, such as measles, chicken pox and other diseases. After some research found that people were infected, the blood will produce some substances can neutralize toxins released by bacteria, known as the “anti-toxins”; or against the bacteria that can manufacture specific proteins, which is later called as “antibodies” thing. Then begin to understand the human immune system to cause infection is resistant microorganisms, can prevent re-infection.

    Human innate immune functions, depending on the genetic parents, can not change; but sometimes because of gene mutations and changes in millions of immune genes, so that problems with immune function. However, for humans in the next few years, may be many genes and their role in the immune system be more clearly, to the innate immune system when a lack of some diseases may have a treatment, or can develop drugs with enhanced capabilities so that the body has a strong resistance against microbes.

Vaccines and Immunization

    The earliest recorded history and use in human vaccines in China around 1100 AD, after which there will be ground into powder smallpox scab inhaled by the nostrils, the records used to prevent smallpox. In about 1721, the British doctor named Jenner found that many milkmaids rarely have smallpox, even got smallpox, the symptoms are relatively mild, so that the cattle of smallpox exposure, you can have a preventive effect, after repeated experiments , in 1796 invented the vaccinia vaccine.

    In about 1870, the French Pasteur can also create a number of vaccine against the bacteria or virus, creating a vaccine manufacturing and a new era of vaccination. Indeed, after the invention of vaccines for many infectious diseases, the incidence decreased, saved many lives, even in 1978, smallpox to have been extinct in the earth, which is entirely dependent on the success of vaccines and vaccination.

    The principle of vaccination is to use the body’s immune system against the foreign invasion of the reaction produced when microorganisms. As long as these micro-organisms to be modified into a non-harmful antigens, through different inoculation into the body to produce specific and effective immune response, can have the recognition of specific microbial capabilities, once the next time encountered when these organisms can be mitigated immediately without infection, the goal of prevention.

    So parents on human immune function and the principle of vaccination should be further recognized, it should be more receptive to their baby vaccinated. After all, prevention is better than cure is the same.
