| keyhole surgery | <procedure> A type of operation performed using a flexible endoscope via a small incision in the skin which allows the instrument to be passed into a cavity. There are now reservations by some experts regarding the use of this procedure in the cancer surgery. (16 Dec 1997) |

| featural surgery | Rarely used term for plastic surgery of the face, for correction or improvement of appearance. (05 Mar 2000) |
| filtering surgery | A surgical procedure used in treatment of glaucoma in which an opening is created through which aqueous fluid may pass from the anterior chamber into a sac created beneath the conjunctiva, thus lowering the pressure within the eye. (hoffman, pocket glossary of ophthalmologic terminology, 1989) (12 Dec 1998) |
| laparoscopically assisted surgery | Operative procedure performed using combined laparoscopic and open techniques; most commonly applied to colon or small intestinal resections with anastomosis. (05 Mar 2000) |
| laparoscopic surgery | Operative procedure performed using minimally invasive surgical technique for exposure that avoids traditional incision. Visualization is achieved using a fibre optic instrument, usually attached to a video camera. (05 Mar 2000) |
| laser surgery | A type of operation using the cutting powers of laser beams from various sources. The use of a laser either to vaporise surface lesions or to make bloodless cuts in tissue. It does not include the coagulation of tissue by laser (laser coagulation). (12 Dec 1998) |
| acid-base balance | The normal balance between acid and base in the blood plasma, expressed in the hydrogen ion concentration or pH, resulting from the relative amounts of acidic and basic materials ingested and produced by body metabolism, compared to the relative amounts of acidic and basic materials excreted from the body and consumed by body metabolism; the normal state of acid-base balance is not one of neutrality, with equal concentrations of hydrogen and hydroxyl ions, but a more alkaline state with a certain excess of hydroxyl ions. Synonym: acid-base equilibrium. (05 Mar 2000) |
| acid-base equilibrium | A condition in which the net rate of acid or alkali production by the body is balanced by the net rate of acid or alkali excretion from the body, resulting in a stable concentration of hydrogen ions in the body fluids. (12 Dec 1998) |
| acid-base imbalance | Disturbances in the acid-base equilibrium of the body. (12 Dec 1998) |
| acrylic resin base | A form made of acrylic resin molded to conform to the tissues of the alveolar process and used to support the teeth of a prosthesis. (05 Mar 2000) |
| aldehyde base | An obsolete term for an imide. (05 Mar 2000) |

| Bandrowski's base | <chemical> Reported cause of anaphylactic reaction. Synonym: n',n'-bis(4-aminophenyl)-2,5-diamino-1,4-quinonediimine (26 Jun 1999) |
| base | <chemistry> The nonacid part of a salt, a substance that combines with acids to form salts, a substance that dissociates to give hydroxide ions in aqueous solutions, a substance whose molecule or ion can combine with a proton (hydrogen ion), a substance capable of donating a pair of electrons (to an acid) for the formation of a coordinate covalent bond. (13 Nov 1997) |
| base analogue | <biochemistry> A chemical which resembles a nucleotide base. They can substitute the Purine and pyrimidine bases that normally appear in DNA, despite minor differences in structure. May be used for inducing mutations, including point mutations. For example: 5 bromouracil can replace thymine or 2 aminopurine replace adenine. (13 Nov 1997) |
