MALAISE is a symptom, often indicative of an
infection, characterized by discomfort, uneasiness, or indisposition.
MALIC ACID (malate) is an acid found in apples and
various other fruits. Malate is involved in many areas of the body. It is one
of the compounds produced in the citric acid cycle as an integral part of the
cycle. Malate is also involved in the transport of compounds through membranes
in the cell.
MALONIC ACID (malonate) is an acid found in aconite
and other plants. Malonic acid is a strong irritant: caution should be taken in
handling it. Malonic acid is an inhibitor of succinate dehydrogenase, which
binds to the enzyme because it is similar in structure to succinate. Once
bound, no reaction occurs because malonate cannot be acted upon by succinate
dehydrogenase. Malonic acid is used in the production of barbiturates.
MALTOL is a volatile oil found in roasted barley and
other plants. Maltol has an odor like that of caramel, and is used as a
flavoring agent in breads and cakes, to achieve a freshly baked odor.
MALTOSE - is a disaccharide found in barley seeds.
Maltose is broken down into two glucose molecules in the intestines by the
enzyme maltase. Failure to break down maltose in the intestine will lead to
diarrhea, excessive gases, and other symptoms. These conditions are due to the
lack of production of enzymes and to the presence of bacteria, which use these
sugars as an energy source. The bacteria decompose these disaccharides into
glucose, with the subsequent production of organic acids, gases, and high
acidity in the lower intestine. Maltose is used as a nutrient, a sweetener, and
in prepared bee food, among other products.
MANNIC DEPRESSIVE: One whose life is easy glum, easy
MANNOSE is a sugar found in red clover tops, caraway
and other plants. Mannose is one of the most important sugars in the body. It
is an important part of globulins, and is found frequently in the
polysaccharides of glycoproteins.
MARRUBENOL is a diterpene alcohol found in
MARRUBIIN is a diterpene lactone found in white
horehound and other plants. Marrubiin promotes secretion of mucus from the
mucous membranes of the air passages, and facilitates its expulsion. Marrubiin
has several pharmacological effects and when changed in a specific way shows
choleretic properties. Marrubiin is used in some cold and cough medications as
MARRUBIOL is a diterpene alcohol found in
MATERNITY WARD: An heirport.
MEDICAGOL is a coumarin derivative and may be
isolated from alfalfa that have viral leaf spot infections among other plants.
Medicagol in some experiments have shown antifungal activity.
MELASMA - A dark pigmentation of the skin.

METABOLISM refers to the sum of all physical and
chemical reactions, including catabolism and anabolism, which occur within an
organism. More simply, it might be considered the physical and chemical
processes of converting protein, fats, carbohydrates and water into living
flesh, energy, and waste products.
METASTASIS is the shifting of a disease, or its local
manifestations from one part of the body to another. Spread is by the lymph
system or bloodstream.
MICELLE is one of the ultamicroscopic units of
MITOCHONDRIA are the rod-shape organelles found in
the cytoplasm of cells. They are the source of energy in the cell and are
involved in protein synthesis and lipid metabolism.
MORPHINE is an alkaloid which can be isolated from
opium. It causes central nervous system excitation followed by depression. It
also depresses respiration, and causes nausea and vomiting in certain
individuals. Morphine is used to relieve pain without loss of consciousness and
as an antidiuretic. Morphine, when abused will lead to physical addiction.
MUCILAGE is a preparation made from vegetables. It
is commonly used to hold pharmaceutical agents in suspension and also used as a
MUCOPOLYSACCHARIDES are polysaccharides that form
bonds with water. They contain hexosamines and sometimes protein. It is a thick
gelatinous material found in many places in the body.
MYALGIA refers to pain located in muscular
MYDRIATIC - any drug that dilates the pupil.
MYELIN SHEATHS are sheaths surrounding the axon of
some (myelinated) nerve cells, consisting of concentric layers of myelin, a
white fluid fatty substance formed in the peripheral nervous system by the
plasma membrane of Schwann cells, and in the central nervous system by
oligodendrocytes. It is interrupted at intervals along the length of the axon
by gaps known as nodes of Ranvier. Myelin is an electrical insulator that
serves to speed the conduction of nerve impulses.
MYOCARDIAL refers to that which concerns the middle
layer of the heart which are composed of cardiac muscle.
MYRISTIC ACID is a fatty acid found in animal and
