| antianaemic principle | The material in liver (and certain other tissues) that stimulates haemopoiesis in pernicious anaemia; for practical purposes, the antianaemic effect of extracts from such tissues is approximately equivalent to the content of vitamin B12. (05 Mar 2000) |
| Bernoulli's principle | <physics> When friction is negligible, the velocity of flow of a gas or fluid through a tube is inversely related to its pressure against the side of the tube; i.e., velocity is greatest and pressure lowest at a point of constriction. Synonym: Bernoulli's principle, Bernoulli's theorem. (05 Mar 2000) |
| pain-pleasure principle | A psychoanalytic concept that, in a human's psychic functioning, he/she tends to seek pleasure and avoid pain; a term borrowed by experimental psychology to denote the same tendency of an animal in a learning situation. Synonym: pleasure principle. (05 Mar 2000) |

| Pauli's exclusion principle | The theory limiting the number of electrons in the orbit or shell of an atom; that it is not possible for any two electrons to have all four quantum numbers identical. (05 Mar 2000) |
| repetition-compulsion principle | In psychoanalysis, the impulse to redramatise or reenact earlier emotional experiences or situations. Synonym: principle of inertia. (05 Mar 2000) |
| melanophore-expanding principle | A polypeptide hormone secreted by the intermediate lobe of the hypophysis in humans (in neurohypophysis in certain other species) which causes dispersion of melanin by melanophores, resulting in darkening of the skin, presumably by promoting melanin synthesis; this effect is readily demonstated in some lower vertebrates, such as frogs and fish; alpha-melanotropin is an N-acetylated peptide with 13 amino acids; beta-melanotropin has 22 amino acids. Synonym: intermedin, melanocyte-stimulating hormone, melanophore-expanding principle. (05 Mar 2000) |
| Mitrofanoff principle | Use of an isolated appendix on a vascularised pedicle as a catheterizable route of access to the bladder from the skin. Synonym: Mitrofanoff principle. Origin: eppendico-+ L. Vesica, bladder, + G. Stoma, mouth (05 Mar 2000) |
| closure principle | In psychology, the principle that when one views fragmentary stimuli forming a nearly complete figure (e.g., an incomplete rectangle) one tends to ignore the missing parts and perceive the figure as whole. See: gestalt. (05 Mar 2000) |
| pleasure-pain principle | The psychoanalytic concept that man instinctively seeks to avoid pain and discomfort and strives for gratification and pleasure. (12 Dec 1998) |
| pleasure principle | A psychoanalytic concept that, in a human's psychic functioning, he/she tends to seek pleasure and avoid pain; a term borrowed by experimental psychology to denote the same tendency of an animal in a learning situation. Synonym: pleasure principle. (05 Mar 2000) |
| consistency principle | In psychology, the desire of the human being to be consistent, especially in his attitudes and beliefs; theories of attitude formation and change based on the consistency principle include balance theory, which suggests that the individual seeks to avoid incongruity in his various attitudes. See: cognitive dissonance theory. (05 Mar 2000) |
