| type 5 glycogenosis | Glycogenosis due to muscle glycogen phosphorylase deficiency, resulting in accumulation of glycogen of normal chemical structure in muscle. Synonym: McArdle's disease, McArdle's syndrome, McArdle-Schmid-Pearson disease, myophosphorylase deficiency glycogenosis. (05 Mar 2000) |

| type 6 glycogenosis | Glycogenosis due to hepatic glycogen phosphorylase deficiency, resulting in accumulation of glycogen of normal chemical structure in liver and leukocytes. Synonym: hepatophosphorylase deficiency glycogenosis, Hers' disease. (05 Mar 2000) |
| type 7 glycogenosis | Phosphofructokinase deficiency of muscle resulting in muscle cramps and myoglobinuria on extreme exertion. The clinical picture resembles type 5 glycogenosis. (05 Mar 2000) |

| type culture | A type strain of microorganism preserved in a culture collection as the standard. (05 Mar 2000) |
| type genus | <zoology> The type of a taxon at the family group level - the nominal genus. (09 Jan 1998) |
| type horizon | <zoology> The geological stratum from which the name-bearing type of a nominal species or subspecies was collected. (09 Jan 1998) |
| type host | <zoology> The host species with which the name-bearing type of a nominal species or subspecies was associated. (09 Jan 1998) |
| type I acrocephalosyndactyly | <paediatrics> A usually inherited disorder characterised by premature closing of the cranial suture lines resulting in a peaked shaped head and abnormal facial appearance. Since it is usually autosomal dominant one or both parents also have the disorder. Surgery is used to correct skull and facial abnormalities. Inheritance: autosomal dominant. (29 Dec 1997) |
| type I cells | Highly attentuated squamous cell's that form the gas-permeable epithelium lining the alveoli of the lungs. Synonym: type I cells. (05 Mar 2000) |
| type I collagen | The most abundant collagen, which forms large well-organised fibrils having high tensile strength. (05 Mar 2000) |
| type I diabetes | A chronic condition in which the pancreas makes little or no insulin because the beta cells have been destroyed. The body is then not able to use the glucose (blood sugar) for energy. IDDM usually comes on abruptly, although the damage to the beta cells may begin much earlier. The signs of IDDM are a great thirst, hunger, a need to urinate often, and loss of weight. To treat the disease, the person must inject insulin, follow a diet plan, exercise daily, and test blood glucose several times a day. IDDM usually occurs in children and adults who are under age 30. This type of diabetes used to be known as juvenile diabetes, juvenile-onset diabetes, and ketosis-prone diabetes. (09 Oct 1997) |
| type I diabetes mellitus | <endocrinology> A severe metabolic disorder which has an abrupt onset before the age of twenty. In it, an insulin deficiency prevents the body from using carbohydrates properly and forces it to rely mainly on protein metabolism. Treatment of the disease includes strict dietary regulation and mandatory insulin injections. (09 Oct 1997) |
