| sickle flap | A sickle-shaped flap from the anterior scalp and one side of the forehead, based on the opposite temporal artery. (05 Mar 2000) |

| sickle form | The male or female gametocyte(s) of Plasmodium falciparum, whose presence in human red blood cells is diagnostic of falciparum malaria. Synonym: crescent, sickle form. Myopic crescent, a white or grayish white crescentic area in the fundus of the eye located on the temporal side of the optic disk; caused by atrophy of the choroid, permitting the sclera to become visible. Synonym: myopic conus. Sublingual crescent, the crescent-shaped area on the floor of the mouth formed by the lingual wall of the mandible and the adjacent part of the floor of the mouth. (05 Mar 2000) |
| sickle scotoma | A comet-shaped scotoma, occurring in glaucoma, attached at the temporal end to the blind spot or separated from it by a narrow gap; the defect widens as it extends above and nasally curves around the fixation spot, and then extends downward to end exactly at the nasal horizontal meridian. Synonym: Bjerrum's sign, sickle scotoma. (05 Mar 2000) |
| aberrant haemoglobin | A mutant Hb that functions abnormally. Compare: variant haemoglobin. (05 Mar 2000) |
| bile pigment haemoglobin | <protein> A protein which is formed from the breakdown of haemoglobin (a protein that carries oxygen in the blood) and is a precursor to the bile pigment biliverdin. (09 Oct 1997) |
| carbon monoxide haemoglobin | <chemical> Chemical name: Haemoglobins, carbonyl- (12 Dec 1998) |
| variant haemoglobin | A harmless mutant form of Hb. (05 Mar 2000) |
| reduced haemoglobin | The form of Hb in red blood cells after the oxygen of oxyhemoglobin is released in the tissues. (05 Mar 2000) |
| mean corpuscular haemoglobin | The haemoglobin content of the average red cell, calculated from the haemoglobin therein and the red cell count, in erythrocyte indices. (05 Mar 2000) |
| mean corpuscular haemoglobin concentration | Hgb/Hct;the average haemoglobin concentration in a given volume of packed red cells, calculated from the haemoglobin therein and the haematocrit, in erythrocyte indices. (05 Mar 2000) |
| glycosylated haemoglobin | <biochemistry> A test which measures the amount of glucose-bound haemoglobin. As the blood glucose level increases the proportion of haemoglobin molecules which bind glucose increases with time. The measurement of glycosylated haemoglobin yields important information regarding how well a patients diabetes is being controlled. (27 Sep 1997) |
| glycosylated haemoglobin test | <investigation> A blood test that measures a person's average blood glucose (sugar) level for the 2- to 3-month period before the test. See: haemoglobin A1C. (09 Oct 1997) |
| green haemoglobin | <protein> A protein which is formed from the breakdown of haemoglobin (a protein that carries oxygen in the blood) and is a precursor to the bile pigment biliverdin. (09 Oct 1997) |
| muscle haemoglobin | <physiology> Protein (17.5 kD) found in red skeletal muscle. It was the first protein for which the tertiary structure was determined by X-ray diffraction, by J.C.Kendrew's group working on sperm whale myoglobin. It is a single polypeptide chain of 153 amino acids, containing a haem group bonded via its ferric iron to two histidine residues. It binds oxygen noncooperatively and has a higher affinity for oxygen than haemoglobin at all partial pressures. In capillaries oxygen is effectively removed from haemoglobin and diffuses into muscle fibres where it binds to myoglobin which acts as an oxygen store. (18 Nov 1997) |
| haemoglobin | <cell biology, haematology> Four subunit globular oxygen carrying protein of the erythrocytes of vertebrates and some invertebrates. It is a conjugated protein containing four haem groups and globin. There are two alpha and two beta chains (very similar to myoglobin) in adult humans, the haem moiety (an iron containing substituted porphyrin) is firmly held in a nonpolar crevice in each peptide chain. There are four globin polypeptide chains, designated alpha, beta, gamma, delta in the adult. Each is composed of several hundred amino acids. (08 Mar 2000) |
