Images Of Poliomyelitis

Glossary
albumin Colloidal protein, coaguable by heat, water soluable, found in egg white, animal tissue, blood plasma, and blood serum.
amoeboid Like an amoeba, the relatively large, mobile protozoa.
amide NH4____+fatty acid
amino acid NH2____, a basic unit of protein, obtained by hydrolysis.
ammonia NH4
bacteriophage Literally, "bacteria eater". Virus that lyse bacteria.
casein Collodial protein, chief protein in cheese
colloidal Very large molecules, a system of dispersed and continuous phases, not a suspension.
embryonic Growing cells, or pertaining to egg, egg-like.
endogenous Originates from within, internal.
exogenous Originates from without, external.
fibrin A fibrous protein generated during blood clotting.
Inclusion body An aggregate of viruses found in cell tissue. HIstorically, the first images of virus structures that could be seen through a optical microscope. "Up to this date [1919, invention of ultra-violet microscope] only viral inclusion bodies had been seen." (Patrick Collard, M.D., The Development of Microbiology (1976))
indol An toxic extract of tar.
in vitro In a petri dish or a flask, outside of the body.
in vivo In the body.
lytic, lysis Having the power to split apart, splitting apart. This may occur when viruses emerge from a cell or are proliferated from a cell.
macrophage A type of leucocyte, a type of white blood cell. Defends the body from alien entities.
monocyte A type of leucocyte, a type of white blood cell. Defends the body from alien entities.
   
myxoma A soft, elastic tumor composed of mucous tissue.
pepsin An enzyme secreted by the stomach. With HCl, aids in the digestion by converting proteins into peptones.
peptide An amide formed from amino acids.
poison Any substance that is harmful or destructive to a living biological system.
protease Any class of enzymes which hydrolyze proteins or peptides.
protein A complex hydrocarbon, usually colloidal. Contains, N, C, H, O, and sometimes sulfur. Can be synthesized by plants but not animals. Usually colloidal.
proteose Formed by the hydrolysis of protein, water soluable.
peptone Produced by the action of pepsin on proteins which are absorbed by the bloodstream.
retrovirus An RNA virus that copies its RNA to DNA in order to insert this DNA into the DNA of a host cell where it is said to lie dormant for possibly decades, awaiting activation. Examples: HIV, and Rous Sarcoma Virus (RSV). THE HIV capsid and genomes are virtually the same size and weight as the picornavirus ("little RNA virus") called poliovirus, with both viruses incorporating virus-encoded transcriptase. Several recent studies have found poliovirus present in victims of postpolio. This suggests that 'dormancy' may also be a characteristic of poliovirus.
roentgen-ray X-ray
Rous sarcoma A sarcoma discovered by Peyton Rous who found it to be caused by the Rous Sarcoma Virus (RSV).
sarcoma A tumor, usually a muscle tumour, containing mostly, various leucocytes.
serum, sera (pl) Blood serum.
SOS Response A cell response to external threat that includes many events, such as the shutting down or attenuation of cellular metabolism, and the accelleration of genetic recombination which may include increased viral activity.
tar sarcoma A sarcoma tumor caused by an injection of coal tar extract (indol) solution. Arsenic and other toxins may be cause a similar effect.
toxin A poison which is derived from a biological source.
trypsin, tryptic A pancreatic enzyme, which splits protein obtained by hydrolysis. A proteolytic enzyme.
