| acceptable daily intake | <pharmacology> This is an estimate of the amount of a substance in food that can be ingested daily over a lifetime by humans without appreciable health risk. The concept of the acceptable daily intake has been developed principally by who and FAO and is relevant to chemicals such as additives to foods, residues of pesticides and veterinary drugs in foods. Acceptable daily intakes are derived from laboratory toxicity data, and from human experiences of such chemicals when this is available, and incorporate a safety factor. The acceptable daily intake is thus an estimate of the amount of a substance in food that can be ingested over a lifetime by humans without significant risk to health (for contaminants in food and drinking water, tolerable intakes - daily or weekly - are used). See: tolerable daily intake. (15 Jan 1998) |

| activities of daily living | The things we normally do in daily living including any daily activity we perform for self-care (such as feeding ourselves, bathing, dressing, grooming), work, homemaking, and leisure. The ability or inability to perform ADLs can be used as a very practical measure of ability/disability in many disorders. (12 Dec 1998) |
| activities of daily living scale | A scale to score physical activity and its limitations, based on answers to simple questions about mobility, self-care, grooming, etc; widely used in geriatrics, rheumatology, etc. (05 Mar 2000) |
| daily dose | The total amount of a remedy that is to be taken within 24 hours. (05 Mar 2000) |
| tolerable daily intake | TDIs are applied to chemical contaminants in food and drinking water. The presence of contaminants is unwanted and they have no useful function, differing from additives and residues where there is or was deliberate use resulting in their presence. TDIs are calculated on the basis of laboratory toxicity data with the application of uncertainty factors. A TDI is therefore an estimate of the amount of a substance (contaminant) in food or drinking water that can be ingested daily over a lifetime without a significant health risk. (09 Oct 1997) |
| macrophages, peritoneal | Mononuclear phagocytes derived from bone marrow precursors but resident in the peritoneum. (12 Dec 1998) |
| panniculitis, peritoneal | Condition of the peritoneum, most commonly of the mesentery, but also of the omentum, characterised by tissue thickening, alteration of fat cells, infiltration of lipid-laden macrophages, and fibrosis. (12 Dec 1998) |
| greater peritoneal cavity | The space enclosed by the peritoneum. It is divided into two portions, the greater sac and the lesser sac or omental bursa, which lies behind the stomach. The two sacs are connected by the foramen of winslow, or epiploic foramen. (12 Dec 1998) |
| peritoneal | <anatomy> Of or pertaining to the peritoneum. Origin: Cf. F. Peritoneal. Source: Websters Dictionary (01 Mar 1998) |
| peritoneal button | A device used to drain ascitic fluid to subcutaneous space. (05 Mar 2000) |
| peritoneal cavity | The space enclosed by the peritoneum. It is divided into two portions, the greater sac and the lesser sac or omental bursa, which lies behind the stomach. The two sacs are connected by the foramen of winslow, or epiploic foramen. (12 Dec 1998) |
| peritoneal dialysis | <nephrology, procedure> In this type of dialysis, a special solution is run through a tube into the peritoneum, a thin tissue that lines the cavity of the abdomen. The bodys waste products are removed through the tube. There are three types of peritoneal dialysis. Continuous ambulatory peritoneal dialysis (CAPD), the most common type, needs no machine and can be done at home. Continuous cyclic peritoneal dialysis (CCPD) uses a machine and is usually performed at night when the person is sleeping. Intermittent peritoneal dialysis (IPD) uses the same type of machine as CCPD, but is usually done in the hospital because treatment takes longer. Haemodialysis and peritoneal dialysis may be used to treat people with diabetes who have kidney failure. (09 Oct 1997) |
| peritoneal dialysis, continuous ambulatory | Portable peritoneal dialysis using the continuous (24 hours a day, 7 days a week) presence of peritoneal dialysis solution in the peritoneal cavity except for periods of drainage and instillation of fresh solution. (12 Dec 1998) |
| peritoneal diseases | Conditions or disorders affecting the peritoneum. (12 Dec 1998) |
| peritoneal exudate | A term most commonly used to describe the fluid drained from the peritoneal cavity some time after the injection of an irritant solution. For example: a standard method for obtaining neutrophil leucocytes is to inject intraperitoneally saline with glycogen (to activate complement) and drain off the leucocyte rich peritoneal exudate some hours later.
