HIV&anti-HIV |
The human immunodeficiency virus (HIV) attacks the body’s immune system. A healthy immune system is what keeps you from getting sick.
BecauseHIV damages your immune system, you are more likely to get sick from bacteria and viruses. It is also harder for your body to fight off these infections when you do get them, so you may have trouble getter better. HIV is the condition that causes acquired immunodeficiency syndrome (AIDS).
HIV can only be passed from person to person through body fluids, such blood, semen and vaginal fluid. Children born to infected mothers can also become infected during pregnancy. The most common waysHIV is passed are:
By having unprotected anal, vaginal or oral sex with an infected person.
By sharing needles and syringes for injecting drugs with an infected person.
What happens after a person gets HIV?
After being infected with HIV, your body works hard to attack the virus. With your body fighting, the virus can’t make as many copies of itself. Even though you still have HIV, you’ll begin to look well and feel well again. The usual blood tests will be normal.
However, during this time, the virus is still attacking your lymph nodes. Lymph nodes are the centers of your body’s immune system. The virus may also attack your brain tissue and slowly cause damage there.
Over 10 to 15 years, HIV kills so many CD4 cells that your body can no longer fight off infections. When your CD4 cell count is 200 or less per mL, you have AIDS (a normal count is 600 to 1000). Once you have AIDS (which stands for acquired immunodeficiency syndrome), you can easily catch many serious infections.
Now, I will introduce 4-Nitrophenyl Chloroformate (CAS代碼：7693-46-1) to you. This is used as a pharmaceutical Intermediates of anti-HIV. If you are interested in this pharmaceutical Intermediates, you can have more information at www.thefabone.com/
