However, the US National Institute of Standards and Technology recommends that, to avoid confusion, any modifiers be instead applied to the quantity being measured rather than the unit of measure. For example, "pg = 100 psi" rather than "p = 100 psig". Differential pressure is expressed in units with "d" appended; this type of measurement is useful when considering sealing performance or whether a valve will open or close. Presently or formerly popular pressure units include the following:

atmosphere (atm)
manometric units:
centimetre, inch, millimetre (torr) and micrometre (mTorr, micron) of mercury,
height of equivalent column of water, including millimetre (mm H2O), centimetre (cm H2O), metre, inch, and foot of water;
imperial and customary units:
kip, short ton-force, long ton-force, pound-force, ounce-force, and poundal per square inch,
short ton-force and long ton-force per square inch,
fsw (feet sea water) used in underwater diving, particularly in connection with diving pressure exposure and decompression;
non-SI metric units:
bar, decibar, millibar,
msw (metres sea water), used in underwater diving, particularly in connection with diving pressure exposure and decompression,
kilogram-force, or kilopond, per square centimetre (technical atmosphere),
gram-force and tonne-force (metric ton-force) per square centimetre,
barye (dyne per square centimetre),
kilogram-force and tonne-force per square metre,
sthene per square metre (pieze). Examples
As an example of varying pressures, a finger can be pressed against a wall without making any lasting impression; however, the same finger pushing a thumbtack can easily damage the wall. Although the force applied to the surface is the same, the thumbtack applies more pressure because the point concentrates that force into a smaller area.
In addition, mitotane has direct and selective cytotoxic effects on the adrenal cortex, via an unknown mechanism, and thereby induces permanent adrenal atrophy similarly to DDD. Chemistry
Analogues of mitotane include aminoglutethimide, amphenone B, and metyrapone. History
Mitotane was introduced in 1960 for the treatment of adrenocortical carcinoma. Society and culture
Generic names
Mitotane is the generic name of the drug and its INN, USAN, BAN, and JAN. Brand names
Mitotane has been sold under the brand name Lysodren. Veterinary use
Mitotane is also used to treat Cushings disease (pituitary-dependent Cushings syndrome) in dogs. The medication is used in the controlled destruction of adrenal tissue, leading to a decrease in cortisol production. References
