Methylene Blue and Hemoglobin

Methylene Blue

(colorless)

+ methemoglobin

Methylene Blue(blue)

+ hemoglobin

*methylene blue plays the role of diaphorase enzyme in converting methemoglobin to hemoglobin. Side effect… blue pee!

*note conjugation across the ring system in methylene blue

*leuco form lacks conjugation.

Demineralization of Teeth Enamel

Enamel…Calcium hydroxyapatite Ca5(PO4)3OH(s) becomes more

soluble in an acid environment (stomach acid)

Calcium fluoroapatite… is a harder form of enamel (fluoride toothpastes and treated water.

Fluoridation… Colorado Brown Stain “Fluorosis”

Gerald J. Cox -initiated public fluoridation of drinking

water, Grand Rapids,Michigan, 1945. Today, 43 of 50 largest U.S. cities have fluoridated water at 0.7-1.2 ppm. (CDC)

Fluoride and Forensics…In The News! Senior researchers from Tennessee's Oak Ridge National Laboratory will search for fluorinated hydrocarbon compounds, one of the approximately 400 types of volatile organic compounds emitted by human bodies during decomposition. It is believed that these

compounds are formed as the fluoride added

to urban drinking water is released after death.

Ethanol is the preferred substrate for alcohol dehydrogenase enzyme

When the alcohol dehydrogenase enzyme metabolizes the ethylene glycol, calcium oxalate crystals form.

Ethanol

ADH…Alcohol dehydrogenase is our primary defense against alcohol, a toxic molecule that depresses the nervous system. High concentrations of alcohol dehydrogenase in the liver and stomach detoxify about approximately one ounce of liquor per hour. The alcohol is converted to acetaldehyde by the oxidation of NAD+ to NADH. Acetaldehyde is even more toxic to the body than ethanol. The body quickly convertes the acetaldehyde into acetate and other molecules that are easily utilized by the cell.

Huffing Toluene (metallic paints) Spray paints are often used as inhalants. Silver,

gold, and clear spray paints are often used to get high. Metallic colors of paints are preferred by users because of their high concentration of toluene, the ingredient in the paint that produces the "high."

Butane Used to refill cigarette lighters. Butyl Nitrate Butyl Nitrate is a substance sold in "head shops" as room

deodorizer. Whippets Whippets are metal canisters that contain Nitrous oxide used to

charge whip cream dispensers.

Carbon Monoxide

Edgar Allen Poe’sdrooping eye and sagging mouth aretell-tale signs of carbon monoxidepoisoning.

Wilson’s DiseaseWilson’s Disease results from the liver’s inability to excrete excess copper. Copper then accumulates in the liver (leading to cirrhosis or fulminant hepatic failure) and in the brain (leading to neurological or psychiatric disturbances).
