.... It is thought to activate the brain stem arousal system and cortex, and, like cocaine, works on the neurotransmitter dopamine. It appears to increase the levels of dopamine in the frontal lobe where attention and impulsive actions are regulated. When taken in its intended form under a doctor's prescritption, it has moderate stimulant properties. There has been a great deal of concern about it's addictive qualities and adverse affects. ADHD is a relatively new disorder. It was introduced in 1980, where it was labeled ADD(attention deficit disorder). In the 1950's, children were simp .....

.... degrees bear watching (Rosenthal, Mark S. MD : A sensible approach. 1997). These behave much the same as those under ten degrees, except that they may progress during growth. Therefore, if a patient has finished growing and has a curve less than twenty degrees, no further treatment or follow-up is needed. A child with a curve between ten and twenty degrees should be examined periodically. Treatment should be started if the curve exceeds twenty degrees. Curves that are discovered when they exceed twenty degrees should get treated immediately, if there is still a potential for growth. .....

.... of teens today are getting their cigarettes from stores, mostly gas stations or convenience store. As teens continue to be able to buy their own cigarettes, more and more communities begin to impose stronger punishments on merchants who sell to the teens. One community has experienced success in their attempts to stop the sale of tobacco products to minors. Woodridge, Illinois, started a program seven years ago which forbade and strictly punished the sale of tobacco products to minors. The entire program includes local licensing of vendors, repeated undercover inspections to see if the s .....

.... Psychological dependence involves a craving for the psychological experience a drug provides. Physical dependence means that the user builds a tolerance to the drug. When this happens the user needs more and more of the drug to achieve the same effect. If a person develops this type of tolerance and then stops using the drug he/she will suffer from drug withdrawal. The body then needs the drug so badly that the user will seek even more of the drug even though it is harmful. This condition is called addiction. Drug addiction ranks as one of the most serious health problems. For example .....

.... what it does, to well. It kills so quickly that the index case, the first person to start an outbreak is usually dead before the proper authorities can show up and try to back track where it came from, defying a decent strategy to keep people away from its natural reservoir. However, it destroys the body so quickly that it doesn't have a chance to spread very far, at least in humans. This virus is a true paradox. Ebola Zaire is a nasty little virus with no known cure. The natural reservoir for the virus is still unknown. If the host could be found, a serum could be made of the antibodie .....

.... illness. Depressed? Sometimes it's hard to know what really is because it has become such a sweeping term, being used to describe everything from deep grief to daily frustrations. But to start with the most rigorous definition, Western psychiatry has a fairly standardized way of diagnosing . Coming from the "Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association", the following are the nine most common symptoms: - extended, unexplained sadness - loss of pleasure in formerly enjoyed activities - sleeping problems - significant weight loss or ga .....

.... characteristics that make up the sex, such as the type of voice, and the physical build. Adrenal steroids, produced in the cortex of the adrenal gland in humans, regulate protein and carbohydrate metabolism. Aldosterone, another steroid produced in the adrenal cortex, plays a role in the mineral and water balance of the body. Anabolic steroids are commercially produced by chemical methods from the male hormone testosterone. Artificial steroids were first developed for medical purposes during World War II (1939-1945) by the German army. The Germans gave it to their soldiers to make them m .....

.... Other concerns of activists that were voiced were that they don't want laws, policies or medical care imposed on women merely as "vectors" who may transmit HIV to their infants. The new guidelines recommend that all pregnant women should receive HIV counseling and testing. These guidelines are aimed at helping pregnant women know their HIV status early so that medical care, including zidovudine (Retrovir, known as AZT, Burroughs Welcome Co., Research Triangle Park, NC), can be made available. The new guidelines also reiterate previous federal health advisories that say counseling should p .....

.... There are two main arguments against that severe pain can and that if some form of killing by doctors, or others were made legal, it might easily be abused and people might be put to death for reasons unconnected with mercy. However, many people see the argument in terms of their own right to die,when faced with the indignity of deterioration, dependence and hopeless pain. Doctors although do at times deliberately give up trying to keep someone alive for whom there is no hope of recovery. There is a clean difference between giving a fatal overdose of a drug to kill a patient and withholdi .....

.... the geographical location in which it was discovered. These filoviruses cause hemorrhagic fever, which is actually what kill victims of the Ebola virus. Hemorrhagic fever as defined in Mosby's Medical, Nursing, and Allied Health Dictionary as, a group of viral aerosol infections, characterized by fever, chills, headache, malaise, and respiratory or GI symptoms, followed by capillary hemorrhages, and, in severe infection, oliguria, kidney failure, hypotension, and, possibly, death. The incubation period for Ebola Hemorrhagic Fever ranges from 2-21 days (JAMA 273: 1748). The blood fails .....
