Secrets Behind Water Saliva

Saliva or saliva is not just fluid in the mouth that are considered disgusting and dirty. There are many things that can be known from the saliva. What are the secrets behind the saliva?

Some people might find sterile saliva or disinfectant, so believe that saliva will more quickly heal wounds. In fact, the mouth is a hotbed of germs and bacteria. There are over 600 types of bacteria in the mouth and saliva that can cause infection.

As reported from MSN on Monday (6/14/2010), following the secret behind saliva:

What is in saliva?

Most of saliva is water, but also contains electrolytes, bacteria, viruses, fungi, secretions from the nose and lungs, cells from the lining of the mouth and about 500 proteins.

Of course, the contents of saliva also depends on what you put into the mouth, such as food debris. Components toothpaste also commonly found in saliva. The content of saliva every person is different.

What can be known from saliva?

Of saliva, can be obtained from DNA samples. In fact, although saliva does not contain the DNA of cells, but cells from the lining of the mouth can be found in saliva samples.

Saliva is also another clue to the identity of a person's menungkapkan. Saliva may reveal what has been eaten and drugs that may be consumed, such as cocaine, marijuana and barbiturates. Scientists can also use saliva samples to show how much of certain drugs in the body.

The scientists also want to be able to use saliva as a tool to detect the disease, because it is much easier, and in many cases more secure. The HIV test is one test which is used as a sample of saliva, although the blood test is still the standard way to test for HIV.

What are the functions of saliva?

Some people do not realize how important functions of saliva, namely:

Break down food in the mouth, so it can be perceived by the tongue and is more easily digested by the stomach.
Clean food and dead cells from the lining of the mouth
Binds food into a ball so that it can be swallowed
Clean food and bacteria from the teeth
Prevent dry mouth lining
Destroying or preventing the growth of certain fungi
Neutralize acids from foods and beverages
Help regenerate the damaged tooth enamel, due to calcium and phosphorus levels

How much amount of saliva?

Goodson estimates that the average person produces about half a liter of saliva a day. But of course this number is also influenced by several factors, among others:

Genes
Time (saliva production slows down drastically at night)
Much water you drink
Was chewing gum or sucking hard candy (both increase the production of saliva)
Smelling something interesting (also increase saliva production, which is why there is the term 'delicious')
More than 400 medications cause a decrease in saliva production
Age production (saliva decreases with age)
Has a condition or disease that affects the production of saliva, such as Sjogren's syndrome, or are undergoing radiation therapy.

Healthy Foods That Can Make Disease

Everything will be good if excessive, including eating healthy foods. Some sources of nutrients can be turned into a source of illness if consumed too much.

The following are some healthy foods, as well as the risks posed if consumed in excessive amounts as quoted from Dailymail, Tuesday (15/06/2010).

Grapefruit
This fruit contains naringenin, which helps regulate blood sugar levels and prevent the metabolic syndrome with a spur liver to burn excess fat. Other content of vitamin C, fiber and phytonutrients.

Although good, consume excessive grapefruit can increase estrogen levels. In older women, eating a quarter of these pieces of fruit a day may increase breast cancer risk by 30 percent.

Turmeric
The content of curcumin in this rhizome has anti-tumor, liver protecting and increasing fat metabolism. According to the American study, eating two servings of curry every week can prevent Alzheimer's.

However consume over 100 mg per day can lead to peptic ulcers. Besides turmeric can also thin the blood, so do not be consumed too much if you have blood clotting disorders or about to undergo surgery.

Soybean
Grains are found in nearly 60 percent of processed foods, such as tofu, tempeh and soy milk. The content of unsaturated fatty acids and high omega 3 good for the heart, in addition to seven essential amino acids essential for healthy muscle to the hair.

On the other hand, soy contains many chemical compounds that inhibit the breakdown of protein, mineral absorption and metabolism. In addition, the content of genistein and daidzein are structurally similar to progesterone could also affect fertility if taken too much.

Chili
Capsaicin content of both to keep the blood circulation and proven effective against tumors. Chillies are also widely used as an effective supporting thermogenesis diet to lose weight.

But according to research at Yale University, the consumption of chili that is too much can increase the risk of stomach cancer in up to 15 percent. Cabe also reduce the protection of the stomach wall, leading to indigestion, acid reflux and even chest pain.

Fish
Salmon, mackarel and sardines contain omega 3 good for the heart, as well as stimulating brain growth. Besides these fish are rich in vitamin D and contain serotonin, a hormone that can boost your mood.

But the waters causing pollution in a number of these fish are contaminated waste including pesticide residues. Contaminant that can inhibit the production of insulin, causing diabetes.

Laser Pointer Also Can Ruin Retina Eye

Laser pointers are often used to help someone when presenting something. But this laser should not be directed into the eye, because it can cause retinal damage.

This was stated by a doctor from Liverpool Hospital and Manchester Royal Eye Hospital. This condition is based on the medical staff conduct operations against a teenager whose eyes were exposed to laser light to cause burns and damage the retina. Examination conducted on adolescents shows the scotomas or black spots in vision.

Although teenagers are still able to have normal vision, but he is at risk of developing problems later in life as a result of damage to the retina.

"Injuries like this are usually caused when a person persistently rubbing his eyes after the eye exposed to laser light," said a spokeswoman from the Health Protection Agency, as quoted by the BBC on Wednesday (16/06/2010).

Experts have realized that this retinal damage that can cause abnormal vision as a result of high power laser pointer. If misused by someone's eyes shone even in a matter of seconds, it can cause damage to the retina.

"The laser pointer is like cheating. At first glance this device seems secure, but it can be very dangerous because it has strong light beam so that the intensity is high," said Barbara McLaughlan, campaigns manager of the Royal National Institute of Blind People.

Research studies on this subject have been published in the British Medical Journal.

Therefore you should never highlight the laser beam toward the eye although it is written that the laser has only milliwatts of power alone. This is because the laser has a focal nature of light, monochromatic and coherent (unidirectional and mutually reinforcing).

Women Twice More Prone to Stress Due to Influence Hormone

Do not be surprised if women are more rapidly with stress and mood changes (mood) than men. This is reinforced by a recent study found that female psychiatric completely controlled by hormones.

Women do have levels of depression, stress disorders and anxiety problems are higher than men. But so far no one has been able to explain these differences are biological.

A recent study conducted in the United States may help explain the difference between the way men and women to control emotions. The study focused on stress hormones called corticotropinreleasing factor (CRF).

CRF is a hormone that helps control the body's reaction to stress. In addition, CRF is also known to play a role in human psychiatric conditions.

"Researchers have known that impaired regulation of CRF in psychiatric disorders associated with stress, so this study are relevant for biological reasons," said Dr. Rita Valentino, from Children's Hospital of Philadelphia who led the study, as reported from Dailymail, Wednesday (16 / 6 / 2010).

Dr. Valentino also said that this could explain why women are two times more susceptible to stress-related disorders than men.

In studies that have been reported in the journal Molecular Psychiatry, it is known that the female brain cells are very pleased with the dose of CRF that are too low for men.

Hormone CRF more closely bound to the protein stress the female brain cells, making it more sensitive to the effects of these hormonal changes. Whereas in men, the brain can reduce the levels of the protein, stop hormones from binding and reducing their impact on the brain.

"Researchers should also investigate the pharmacology of CRF antagonists are used as medicine for the treatment of depression. Giving medicine may need to consider gender differences at the molecular level," added Dr. Valentino.

Why Women Love Make More Fat?

Most women who are married, moreover, already had a baby will have a slightly stretchy aka body fat. And many of them think that this is love. But why love makes a woman become obese?

Getting married and having children is the happiest thing for women. But there are things that are sometimes forgotten by most women, the love of husband and children had to make the body into fat.

"In addition to being mothers and menopausal, married women who do not have children at the age of 20 or 30 years will also have greater weight than single women. And when they have children, their weight will increase again," said Annette Dobson, researchers and professor of biostatistics at the University of Queensland, as reported from IndiaVision, Wednesday (16/06/2010).

It is based on the results of a study of 6458 Australian women who have been married for over 10 years but has no children. On average their weight will go up about 7 kg from before marriage.

"What we do not know is why get married and have a spouse to make women become obese," Dobson wrote in the Sydney Morning Herald.

Dobson said that his study results, that married and have a spouse to change eating habits of a woman. Eating habits men will be accommodated to the wife, so that makes women more frequent meals and make more fat, although not yet had children.

In addition to changes in frequency of eating, Wendy Brown, professor of physical activity and health, and lead author of the Australian Longitudinal Study on Women's Health Study also suggests another reason, namely the cessation of routine activities of a married woman.

Most married women choose to become a housewife and stay home to take care of the child. If at the time of single women are active and always busy, then silence in the house will make it a 'cocoon' that fat.

Women who already have a husband would want to spend more time with your spouse or children, so sometimes he stops to do some important things for the body, such as sports.

"This is not because women do not have the time, but rather a change in priorities. Sometimes they feel selfish when do the things they want to do for himself," added Wendy Brown.
