| cellular immunodeficiency with abnormal immunoglobulin synthesis | An ill-defined group of sporadic disorders of unknown cause, occurring in both males and females and associated with recurrent bacterial, fungal, protozoal, and viral infections; there is thymic hypoplasia with depressed cellular (T-lymphocyte) immunity combined with defective humoral (B-lymphocyte) immunity, although immunoglobulin levels may be normal. Synonym: Nezelof syndrome, Nezelof type of thymic alymphoplasia. (05 Mar 2000) |

| haemoglobins, abnormal | Haemoglobins altered in their genetically determined molecular structure, resulting in a characteristic complex of vlinival and laboratory abnormalities. The specific features of the abnormal haemoglobins are related to variation of the composite globin polypeptide chains. (12 Dec 1998) |
| pupillary functions, abnormal | Conditions in which the pupil does not react normally to dilation and constriction. Signs of pupillary abnormalities originate from the pupil's shape, position, and response to stimulation. (12 Dec 1998) |
| fibrinogens, abnormal | Fibrinogens which have a functional defect as the result of one or more amino acid substitutions in the amino acid sequence of normal fibrinogen. Abnormalities of the fibrinogen molecule may impair any of the major steps involved in the conversion of fibrinogen into stabilised fibrin, such as cleavage of the fibrinopeptides by thrombin, polymerization and cross-linking of fibrin. The resulting dysfibrinogenaemias can be clinically silent or can be associated with bleeding, thrombosis or defective wound healing. (12 Dec 1998) |
| placental | 1. Of or pertaining to the placenta; having, or characterised by having, a placenta; as, a placental mammal. 2. <zoology> Of or pertaining to the Placentalia. <zoology> One of the Placentalia. Source: Websters Dictionary (01 Mar 1998) |
| placental abruption | <obstetrics> An third trimester complication that results from the haemorrhage and accumulation of blood between the placenta and the wall of the uterus. This inevitably interferes with foetal oxygenation and often necessitates the need for emergency cesarean section delivery. (31 Dec 1997) |
| placental barrier | The semipermeable layer of foetal tissue separating the maternal from the foetal blood in the placenta; composed of: 1) endothelium of the foetal vessels in the chorionic villi, 2) stromata of the villi, 3) cytotrophoblast (negligible after the fifth month of gestation), and 4) syncytial trophoblast covering the villi; the placental membrane acts as a selective membrane regulating passage of substances from the maternal to the foetal blood. Synonym: placental barrier. (05 Mar 2000) |
| placental calcium-binding protein | <protein> Calcium binding protein of placenta, uterus and vasculature containing the EF hand motif. (18 Nov 1997) |
| placental chorioangioma | <radiology> Most common benign tumour of placenta, incidence: 0.7%, Differential diagnosis: hydatidaform mole, large leiomyoma, chorioepithelioma, complications: IUGR, foetal anomaly, polyhydramnios, haemorrhage, heart failure, premature labour (12 Dec 1998) |
| placental circulation | The circulation of blood through the placenta during intrauterine life, serving the needs of the foetus for aeration, absorption, and excretion; also, maternal circulation through the intervillous space of the placenta. (05 Mar 2000) |
| placental dysfunction | 1. Denoting faulty development or ripening; often connoting structural and/or functional abnormalities. 2. In obstetrics, denoting an infant whose birth weight is inappropriately low for its gestational age. 3. Immature development of the placenta so that normal function does not occur. Synonym: placental dysfunction. (05 Mar 2000) |
| placental dysfunction syndrome | <syndrome> Foetal malnutrition and hypoxia resulting from impaired transfer of oxygen and various nutritive materials from mother to foetus. (05 Mar 2000) |
| placental dysmature | Immature development of the placenta so that normal function does not occur. (05 Mar 2000) |
| placental dystocia | Trouble delivering the placenta (the afterbirth). Dystocia comes from the greek dys meaning difficult, painful, disordered, abnormal + tokos meaning birth. (12 Dec 1998) |
| placental extracts | Extracts prepared from placental tissue; they may contain specific but uncharacterised factors or proteins with specific activities. (12 Dec 1998) |
