What is Gamma Globulin?

Gamma globulin is found in the blood. It is also called immunoglobulin and it is a type of protein. It is also a type of antibody that helps the body fight disease. Gamma globulin can even be taken from one individual and given to another in order to help them boost their own immune system. This can then be used to prevent disease or combat a disease already present in the body. Immunoglobulin is not only to be found in humans; it is also present in most mammals.

How Gamma Globulin Works

This type of antibody is usually administered by injection. It is effective in those situations where the individual’s immune system does not have the necessary antibodies to combat a disease. When we get a disease the body will develop antibodies to fight against it. This means that should the same disease attack in the future the body will have resistance in the form of these proteins. Of course if the individual has not had the disease then they will not have the resistance. Gamma globulin offers temporary resistance because it contains the proteins to fight the disease.

The way it all works can be better understood with the aid of an example. If an individual has had measles their body will have produced gamma globulin which will provide resistance if they come in further contact with the disease. This protein could be passed onto another individual by way of injection and this would temporarily pass on immunity to them. Nowadays we have a lot more vaccines than in the past so there is less need to use other people’s antibodies to fight individual diseases. Instead gamma globulin is mostly used to help people who have problems with their immune system.

Another way that this antibody is used is to treat immunological diseases. Sometimes the immune system can malfunction and this leads to a situation where it is attacking itself. A good example of this is Thrombocytopenic purpura. Here the immune system can attack platelets and this is dangerous because these are needed for blood clotting. By using immunoglobulin though, this immune system attack on the body is stopped.

Dangers of Gamma Globulin

If the body has too much immunoglobulin then this can also be problematic. It is often the sigh of damaged immune system. This could be caused by a disease such as HIV or cancer. When gamma globulin is too high in the body it is referred to as hypergammaglobulinemia. Another possible danger with these injections is that it could possible lead to heart problems. This is why those who are undergoing this treatment will be monitored and told to inform the doctor of any strange reactions right away. Most of those who have these injections won’t have to deal with any adverse reactions.

Gamma globulin is an important part of our immune defenses. Sometimes our own immunity is not enough to fight off disease but luckily we can benefit from the immunoglobulin of other people.

How to Faint in Public?

faintFainting in public is always a great way to get noticed. This temporary loss of consciousness occurs due to a decreased flow of blood to the brain. What usually happens during a faint is that not only do we briefly lose consciousness but also muscle tone as well. This is why people will fall down in public and instantly become the star of the show. Some people will mistake fainting with falling into unconsciousness due to some type of head trauma; the two are quite different even though they may look the same. With fainting there is no trauma to the brain but just a lack of oxygen. If you want to impress people then why not use the fancy name for fainting – it is called syncope.

The Causes of Fainting

There are many possible causes of fainting; anything that interferes with the ability of blood to reach the brain will lead to this event. If for some crazy reason you actually wanted to faint there are many ways to encourage this event; we will examine these here:

  • One of the more common reasons for fainting is dehydration. What happens here is that the body does not have enough fluid inside the system to keep the brain adequately supplied. This dehydration could occur for many possible reasons. We might have some type of food poisoning which means that we are losing fluids through vomiting and diarrhoea. We might have spent too long in the heat and didn’t bother to drink anything to replace the fluid lost through perspiration. Anything that causes our fluid level in the body to fall will greatly increase our chances of fainting.
  • The vagus nerve plays a very importing role in fainting as this can be responsible for redirecting blood away from the brain to the digestive system. Some people have a vagus nerve that is a bit trigger happy and so will overdo it when redirecting blood away from the brain and this can lead to a fainting spell. For some people a sudden fight or a lot of anxiety in their life will be enough to have this vagus nerve working overtime and causing fainting spells.
  • Hypotension means that our blood pressure is too low and this can also lead to a syncope attack.
  • Another frequent cause of this type of event is alcohol or drugs. Alcohol works in a number of ways to bring on a faint. On one hand it is a diuretic; this means that you pee a lot. This means that even though you might be drinking a lot of alcohol you can still end up dehydrated. Another way that alcohol causes syncope is that it relaxes the blood vessels causing them to dilate – leading to a fall in pressure. The different drugs, both legal and illegal, can work in different ways to cause a faint.
  • Any type of cardiac problem can lead to this type of episode because it will interfere with the ability of blood to reach the brain.
