Originally developed by scientists at Mead Johnson, it has been used for more than 30 years to reduce upper respiratory mucous secretions & thus to help with a variety of upper respiratory ailments. It works by cleaving certain chemical bonds found in mucous.

NAC also provides immune support. A double blind 6 month study in the elderly showed NAC significantly reduced the frequency, severity, & duration of flu-like episodes.

NAC supports liver detoxification pathways (phase II glucoronidation.)

Low cysteine levels are often found in HIV patients. They have been found to be helped by NAC, which protected against mitochondrial DNA damage, which in turn decreased the replication of the virus.

NAC may be used to:

• Decrease chronic sinusitis, chronic middle ear infections, symptoms & flareups.
• Help emphysema, & other chronic obstructive lung disease symptoms.
• Useful with liver disorders.
• Protect against alcohol, tobacco, auto exhaust, & other chemical toxicity.
• Protect against the side effects of some chemotherapy agents, & radiation treatment.
• For a precursor to increase your body's levels of glutathione.
• Treat Tylenol overdoses.

A study of exhaled breath in New Jersey residents showed the appearance of at least 10 known neurotoxicants in "otherwise healthy individuals." These neurotoxicants included carbon tetrachloride, chloroform, dichlorobenzene, ethyl benzene, styrene, tetrachloroethylene, trichloroethane, trichloroethylene, xylene, and benzene.

Chemical that transmits information across the junction (synapse) that separates one nerve cell (neuron) from another nerve cell or a muscle. Neurotransmitters are stored in the nerve cell's bulbous end (axon). When an electrical impulse traveling along the nerve reaches the axon, the neurotransmitter is released and travels across the synapse, either prompting or inhibiting continued impulses. There are more than 300 known neurotransmitters, including the endorphins and acetylcholine.

Niacin commonly causes a flush of the skin characterized by a prickly hot sensation & possibly itching. This is more apt to occur when it is taken with an inadequate amount of food & is therefore absorbed more quickly than it is with a larger meal. Onset of the flush is within 20 minutes-1 hour & it usually lasts 20 minutes-1 1/2 hours. Some people like the feeling, others don't.

Nickel is a light gray metal used primarily in stainless and specialty steel production, plating and high-temperature alloys. The stainless steel sector consumes about two-thirds of the world's primary nickel. U.S. production of nickel-bearing stainless steel was 12 percent greater in 1997 than in 1996 despite a slowdown in the second half of 1997, according to the U.S. Geological Survey. Since 1975, world demand for stainless steel has grown at an average of 4.5 percent per year. Analysts said they believed the growth rate will continue or even accelerate over the next 20 years, encouraging extensive new nickel mines in North America, Australia and Oceania.

• Potatoes
• Eggplants
• Tomatoes
• Peppers

People with autoimmune diseases such as arthritis and psoriasis should avoid the nightshades as they cause flare-ups of autoimmune symptoms.

Many arthritics have already associated the ingestion of nightshade vegetables (tomato, potato, eggplant and peppers) with an increase in symptoms. Researchers have suggested that this connection is due to the solanine (a poisonous chemical substance) content of these foods.

• 1. a colorless, gaseous element found free in the air; symbol, N; specific gravity, 0.9713; atomic number, 7; atomic weight, 14.007. It constitutes part of the atmosphere, forming about four fifths of common air. Chemically, it is almost inert, but forms by combination nitric acid and ammonia. Nitrogen is important biologically, being a constituent of protein and nucleic acids and thus present in all living cells. It is a gas unfitted to support respiration: not a poison, but proving fatal if breathed alone, because of the want of oxygen. It is soluble in the blood and body fluids and when released as bubbles of gas by reduction of atmospheric pressure causes serious symptoms.
• 2. N₂; nitrogen containing not less than 99 per cent, by volume, of N₂. It is used to replace air in pharmaceutical preparations.

In CFIDS NMDA receptors become substantially more active than GABA receptors, so stimuli like light and noise, which ordinarily would not cause an experience of pain, become able to do so.

See Bedwetting

As a diuretic, nopal helps prevent sugars, fat and starch from entering into the bloodstream and attaching to artery walls. Nopal supports healthy liver and pancreas functions and is beneficial for the prostate gland.

Nopal stimulates urine flow, neutralizing toxins and waste in the body. Nopal helps cleanse the bladder and lymphatic system, lowering sugar levels in the blood.

Nopal may also be used to help reduce fevers by stimulating perspiration. Nopal has been known to treat respiratory problems and contribute to the lowering of blood pressure and cholesterol levels.

This type of bleeding comes from the breaking open of small capillaries in the mucous membranes of the cartilage septum which divides the nose into two passageways. The cause of bleeding is due to a drying out of the membranes because of a lack of moisture in the air both inside and outside the home.

Bleeding is usually slight or moderate at most, for it comes from very small capillaries. Because of its location, bleeding can be stopped pretty easily by direct pressure with the finger pressed over the nostril on the involved side. Sometimes it is helpful for you to sit down, relax, and place cold compresses over your face and nose.

• 1. either of the membranes, inner and outer, comprising the nuclear envelope.
• 2. nuclear envelope.

• 1. the central core of an object or body.
• 2. a cell nucleus: a spheroid body within a cell, consisting of a number of characteristic organelles visible with the optical microscope, a thin nuclear membrane, a nucleolus or nucleoli, irregular granules of chromatin and linin, and a diffuse nucleoplasm.
• 3. a group of nerve cells ordinarily located within the central nervous system and bearing a direct relationship to the fibers of a particular nerve.
• 4. in organic chemistry, the combination of atoms forming the central element or basic framework of the molecule of a specific compound or class of compounds.
