suppression [sŭ-presh´un]
suppression,
suppression
1. the act of holding back or checking.
2. sudden stoppage of a secretion, excretion, or normal discharge.
3. in psychiatry, conscious inhibition of an unacceptable impulse or idea as contrasted with repression, which is unconscious.
4. in genetics, masking of the phenotypic expression of a mutation by the occurrence of a second (suppressor) mutation at a different site from the first; the organism appears to be reverted but is in fact doubly mutated.
5. inhibition of the erythrocytic stage of plasmodium as prophylaxis for clinical attacks of malaria.
6. cortical inhibition of perception of objects in all or part of the visual field of one eye during binocular vision.
bone marrow suppression suppression of bone marrow activity, resulting in reduction in the number of platelets, red cells, and white cells.
overdrive suppression transient suppression of automaticity in a cardiac pacemaker following a period of stimulation by a more rapidly discharging pacemaker.
sup·pres·sion (s -pr sh n)n. 1. The act of suppressing or the state of being suppressed. 2. Conscious exclusion of unacceptable desires, thoughts, or memories from the mind. 3. The sudden arrest of the secretion of a fluid, such as urine or bile. 4. The checking or curtailing of an abnormal flow or discharge. 5. The effect of a second genetic mutation that reverses a phenotypic change that had been caused by a previous mutation at a different location on the chromosome. |
suppression
[səpresh′ən]
Etymology: L, supprimere
(in psychoanalysis) the conscious inhibition of or effort to conceal unacceptable or painful thoughts, desires, impulses, feelings, or acts. Compare repression.
suppression [sŭ-presh´un]
the act of holding back or checking.
1. the stopping or inhibition of something, such as a secretion, excretion, normal discharge, or other function.
2. in psychiatry, conscious inhibition of an unacceptable impulse or idea as contrasted with repression, which is unconscious.
3. in genetics, a second mutation occurring at a site different from the first mutation site and able to mask or suppress the phenotypic expression of the first mutation; the organism appears to be reverted but is in fact doubly mutant.
4. inhibition of the erythrocytic stage of Plasmodium to prevent clinical attacks of malaria; used for prophylaxis.
5. cortical inhibition of perception of objects in all or part of the visual field of one eye during binocular vision.
bone marrow suppression reduction of the cell-forming functions of bone marrow, such as by a drug or because of replacement of the marrow by a disease process. Called also myelophthisis and myelosuppression.
labor suppression in the nursing interventions classification, a nursing intervention defined as controlling uterine contractions prior to 37 weeks of gestation to prevent preterm birth. See also labor.
lactation suppression in the nursing interventions classification, a nursing intervention defined as facilitating the cessation of lactation and minimizing breast engorgement after childbirth.
overdrive suppression the suppression of intrinsic cellular automaticity by a rapid outside stimulus. In cardiology this refers to the inhibitory effect of a faster pacemaker on a slower pacemaker. The faster rate causes an accumulation of intracellular sodium, stimulating the sodium-potassium pump, which hyperpolarizes the cell so that it takes longer to reach threshold potential. This phenomenon is present in healthy His-Purkinje cells but decreases with a decrease in membrane potential and loss of fast sodium channels.
suppression,
n 1., in naturopathic medicine, the successful relief of symptoms without curing the underlying illness or disease.
2., in homeopathy, the elimination of symptoms, often with topicals, without curing deeper aspects of the disease. Thought to result in more serious inner disease later.

suppression
1. sudden stoppage of a secretion, excretion or normal discharge.
2. in genetics, restoration of a lost function by a second mutation either in a gene other than that involved in the primary mutation, or within the same gene.
suppression
The process by which the brain inhibits the retinal image (or part of it) of one eye, when both eyes are simultaneously stimulated. This occurs to avoid diplopia as in strabismus, in uncorrected anisometropia, in retinal rivalry, etc. Syn. suspenopsia (this term actually refers to voluntary suppression as occurs, for example, when using a monocular microscope with one eye); suspension (most often used when referring to partial suppression). See cheiroscope; physiological diplopia; Javal's grid; Mallett fixation disparity unit; Remy separator; retinal rivalry; Bagolini lens test; four prism dioptre base out test; FRIEND test; Turville infinity balance test; Worth's four dot test; vectogram.
suppression
Slowing down, restraint, inhibition Psychiatry The conscious effort to control and conceal unacceptable impulses, thoughts, feelings, acts
