| biologic evolution | Biologic evolution was contrasted with cultural evolution in 1968 by A.G. Motulsky who pointed out that biologic evolution is mediated by genes, shows a slow rate of change, employs random variation (mutations) and selection as agents of change, new variants are often harmful, these new variants are transmitted from parents to offspring, the mode of transmission is simple, complexity is achieved by the rare formation of new genes by chromosome duplication, biologic evolution occurs with all forms of life, and the biology of humans requires cultural evolution. See Cultural evolution. (12 Dec 1998) |
| biologic time | The concept that our appreciation of time varies with age and is governed by the neural organization of the individual; it obeys a logarithmic rather than an arithmetic law. (05 Mar 2000) |

| a' haemolysis | Haemolysis observed infrequently in blood agar cultures of occasional strains of streptococci; the zone of haemolysis about the colony is not as clear, or wide, or distinctly outlined as it is in b haemolysis; there are a few apparently intact erythrocytes throughout the zone, but they are more numerous in the immediate vicinity of the colony, and there is no discoloration as there is in a haemolysis; the unique feature is that the zone becomes wider, i.e., the process is stimulated, when the culture is incubated at refrigerator temperatures (not true for b haemolysis); some strains of streptococci that are a'-haemolytic on horse blood agar cause typical a haemolysis on rabbit blood agar. (05 Mar 2000) |
| b haemolysis | Complete or "true" haemolysis observed in blood agar cultures of various bacteria, especially haemolytic streptococci and staphylococci; virtually all of the erythrocytes are destroyed in a relatively wide, regularly circumscribed, circular zone about the colony, thereby resulting in a clear "halo" of transparent agar; the zone of haemolysis is frequently much wider than the diameter of the colony; the degree of change varies with species of erythrocytes, e.g., those of sheep and rabbits are usually more easily haemolyzed than those of man, and so on; the haemolysin acts extracellularly (in the absence of the bacterial cells) and may be quantitatively estimated by means of tube-dilution tests of a bacteria-free filtrate (containing the haemolytic substance) with a suspension of erythrocytes. (05 Mar 2000) |
| venom haemolysis | That caused by haemolytic material in the venom of various species of snakes or other venomous animals. (05 Mar 2000) |
| g haemolysis | A term sometimes used to indicate that there is no haemolysis in relation to bacterial colonies in or on blood agar; thus, nonhemolytic organisms may be referred to as producing g haemolysis. (05 Mar 2000) |
| viridans haemolysis | See: a' haemolysis. (05 Mar 2000) |
| phenylhydrazine haemolysis | An in vitro test for G6PD deficiency; haemolysis resulting from in vitro addition of phenylhydrazine to blood with red cells which are deficient in glucose-6-phosphate dehydrogenase (G6PD), with the appearance of Heinz-Ehrlich bodies. (05 Mar 2000) |
| conditioned haemolysis | Haemolysis caused by complement when erythrocytes have been sensitised by specific complement-fixing antibody. Synonym: conditioned haemolysis. (05 Mar 2000) |
| haemolysis | <haematology> Disruption of the integrity of the red cell membrane causing release of haemoglobin. Haemolysis may be caused by bacterial haemolysins, by antibodies that cause complement dependent lysis, by placing red cells in a hypotonic solution or by defects in the red cell membrane. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
| sucrose haemolysis test | Isotonic sucrose promotes binding of complement to red blood cells; in paroxysmal nocturnal haemoglobinuria a proportion of the cells is sensitive to complement-mediated lysis, and haemolysis ensues. (05 Mar 2000) |
| immune haemolysis | Haemolysis caused by complement when erythrocytes have been sensitised by specific complement-fixing antibody. Synonym: conditioned haemolysis. (05 Mar 2000) |
