No:360 - comatose: pertaining to or affected with coma.
No:361- combination: the result or product of combining; a series of events or result occurring in an ordered sequence; the act or process of combining; the act or process of uniting to form a chemical compound : the chemical compound so formed.
No:362 - comedo: a plug of keratin and sebum within the dilated orifice of a hair follicle, frequently containing the bacteria Propionibacterium acnes, Staphylococcus albus, and Pityrosporon ovale; called also blackhead. See also acne.
No:363 - commensal: (L. com- together + mensa table) 1. living on or within another organism, and deriving benefit without injuring or benefiting the other individual. 2. an organism living on or within another, but not causing injury to the host.
No:364 - commotion: (L. 'disturbance') a concussion; a violent shaking, or the shock which results from it.
No:365 - compatible: 1. capable of harmonious coexistence; of medications, suitable for simultaneous administration without nullification or aggravation of the effects of either. 2. denoting a donor and recipient of a blood transfusion in which there is no transfusion reaction. 3. histocompatible; denoting a donor and recipient of an organ transplant that is not rejected.
No:366 - compensation: (L. compensatio, from cum together + pensare to weigh) the counterbalancing of any defect of structure or function. In psychology, a conscious process or, more frequently, an unconscious defense mechanism by which a person attempts to make up for real or imagined physical or psychological deficiencies. In cardiology, the maintenance of an adequate blood flow without distressing symptoms, accomplished by such cardiac and circulatory adjustments as tachycardia, cardiac hypertrophy, and increase of blood volume by sodium and water retention.
No:367 - competitive: relating to, characterized by, arising from or designated to exhibit rivalry among two individuals or forces.
No:368 - complement: a term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
No:369 - complementary: (L. complere to fill) supplying a defect, or helping to do so; making complete; accessory.
No:370 - complex: (L. complexus woven together, encompassing) complicated, not simple.
No:371 - complication: (L. complicatio from cum together + plicare to fold) 1. a disease or diseases concurrent with another disease. 2. the concurrence of two or more diseases in the same patient.
No:372 - component: a constituent element or part; specifically in neurology, a series of neurons forming a functional system for conducting the afferent and efferent impulses in the somatic and splanchnic mechanisms of the body.
No:373 - concentration: (L. concentratio) 1. increase in strength by evaporation. 2. the ratio of the mass or volume of a solute to the mass or volume of the solution or solvent.
No:374 - conception: (L. conceptio) the onset of pregnancy, marked by implantation of the blastocyst; the formation of a viable zygote.
No:375 - concomitant: (L. concomitans from cum together + comes companion) accompanying; accessory; joined with another.
No:376 - concrete: (L. concretus) solid, tangible.
No:377 - condition: a mode or state of being; the state of being fit : the physical status of the body as a whole, or of one of its parts - usually used to indicate abnormality.
No:378 - conduction: (L. conductio) the transfer of sound waves, heat, nervous impulses, or electricity.
No:379 - condyloma: (Gr. kondyloma, knuckle or knob) c. acuminatum; a papilloma with a central core of connective tissue in a treelike structure covered with epithelium, usually occurring on the mucous membrane or skin of the external genitals or in the perianal region.
