| 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) |
| Gant's clamp | A right-angled clamp used in haemorrhoidectomy. (05 Mar 2000) |
| Gaskell's clamp | An instrument for crushing the atrioventricular bundle in experimental animals and thus producing heart block. (05 Mar 2000) |
| Rankin's clamp | A three-bladed clamp used in resection of colon. (05 Mar 2000) |
| gingival clamp | A springlike metal piece encircling or grasping the cervix of a tooth and shaped so as to retract the gingival tissue. (05 Mar 2000) |
| Payr's clamp | A clamp used in gastrectomy or enterectomy. (05 Mar 2000) |
| glucose clamp technique | <technique> Maintenance of a constant blood glucose level by perfusion or infusion with glucose or insulin. It is used for the study of metabolic rates (e.g., in glucose, lipid, amino acid metabolism) at constant glucose concentration. (12 Dec 1998) |
| voltage clamp | <physiology, technique> A technique in electrophysiology, in which a microelectrode is inserted into a cell and current injected through the electrode so as to hold the cells membrane potential at some predefined level. The technique can be used with separate electrodes for voltage sensing and current passing, for small cells, the same electrode can be used for both. Voltage clamp is a powerful technique for the study of ion channels. See: patch clamp. (18 Nov 1997) |
| Goldblatt's clamp | A clamp applied experimentally to the renal artery to damp pulse pressure and thereby produce chronic hypertension by activation of the renin-angiotensin system. (05 Mar 2000) |
| right angle clamp | A clamp with a short 90 |
| rubber dam clamp | A springlike metal piece encircling or grasping the cervix of a tooth and so shaped as to prevent a rubber dam from coming off the tooth. (05 Mar 2000) |
| rubber dam clamp forceps | A forceps with pronged jaws designed to engage the jaws of a rubber dam clamp so that they may be separated to pass over the widest buccolingual contour of a tooth. Synonym: rubber dam clamp forceps. (05 Mar 2000) |
| rubber shod clamp | A small rubber-tipped clamp that holds sutures in place during surgery. (05 Mar 2000) |
| Mikulicz clamp | A clamp used to crush walls between proximal and distal colon in two-stage colectomy. (05 Mar 2000) |
