| patch-clamp techniques | An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.

| patch test | A test of skin sensitiveness: a small piece of paper, tape, or a cup, wet with CO non-irritating diluted test fluid, is applied to skin of the upper back or upper outer arm and after 48 hours the area previously covered is compared with the uncovered surface; an erythematous reaction with vesicles occurs if the substance causes contact allergy. See: photo-patch test. (05 Mar 2000) |
| patch tests | Skin tests in which the sensitiser is applied to a patch of cotton cloth or gauze held in place for approximately 48-72 hours. It is used for the elicitation of a contact hypersensitivity reaction. (12 Dec 1998) |
| peyer's patch | One of the lymphatic nodule aggregates existing in the intestines. (09 Oct 1997) |
| photo-patch test | A test of contact photosensitization: after application of a patch with the suspected sensitiser for 48 hours to two sites, if there is no reaction one area is exposed to a weak erythema dose of sunlight or ultraviolet light; if positive, a more severe reaction with vesiculation develops at the exposed patch area than the nonexposed skin patch site.

| moth patch | <dermatology> Melasma cholasma hepaticum a term formerly used to refer to circumscribed facial hyperpigmentation resembling melasma that may occur as a cutaneous manifestation of chronic liver disease. Origin: Gr. Chloazein = to be green (18 Nov 1997) |
| whole cell patch | <physiology> A variant of patch clamp technique, in which the patch electrode seals against the cell, with direct communication between the interior of the electrode and the cytoplasm. (18 Nov 1997) |
| mucous patch | An oval to round, yellow-gray to white, membrane-covered lesion or lesions occurring on the mucous membranes; usually seen in secondary syphilis. (05 Mar 2000) |
| salmon patch | Interstitial or parenchymatous keratitis giving rise to neovascularization of the cornea. Synonym: Hutchinson's patch. (05 Mar 2000) |
| herald patch | The initial rapidly enlarging oval-shaped red papulosquamous lesion, usually on the trunk, heralding the widespread eruption of pityriasis rosea, and preceding the latter by 7-14 days. (05 Mar 2000) |
| Hutchinson's patch | Interstitial or parenchymatous keratitis giving rise to neovascularization of the cornea. Synonym: Hutchinson's patch. (05 Mar 2000) |
| shagreen patch | An oval-shaped nevoid plaque, skin-coloured or occasionally pigmented, smooth or crinkled, appearing on the trunk or lower back in early childhood; sometimes seen with other signs of tuberous sclerosis. Synonym: shagreen patch. (05 Mar 2000) |
| inside out patch | A variant of the patch clamp technique, in which a disc of plasma membrane covers the tip of the electrode, with the inner face of the plasma membrane facing outward, to the bath. (18 Nov 1997) |
| opaline patch | A mucous patch of silver-gray appearance. (05 Mar 2000) |
| outside out patch | A variant of patch clamp technique, in which a disc of plasma membrane covers the tip of the electrode, with the outer face of the plasma membrane facing outward, to the bath. (18 Nov 1997) |
