| porphyria | A pathological state in man and some lower animals that is often due to genetic factors, is characterised by abnormalities of porphyrin metabolism and results in the excretion of large quantities of porphyrins in the urine and in extreme sensitivity to light. (18 Nov 1997) |
| porphyria cutanea tarda | A form of hepatic porphyria (porphyria, hepatic) characterised by photosensitivity resulting in bullae that rupture easily to form shallow ulcers. This condition occurs in two forms: a sporadic, nonfamilial form that begins in middle age and has normal amounts of uroporphyrinogen decarboxylase with diminished activity in the liver; and a familial form in which there is an autosomal dominant inherited deficiency of uroporphyrinogen decarboxylase in the liver and red blood cells. (12 Dec 1998) |
| porphyria cutanea tarda hereditaria | A form of hepatic porphyria (porphyria, hepatic) characterised by photosensitivity resulting in bullae that rupture easily to form shallow ulcers. This condition occurs in two forms: a sporadic, nonfamilial form that begins in middle age and has normal amounts of uroporphyrinogen decarboxylase with diminished activity in the liver; and a familial form in which there is an autosomal dominant inherited deficiency of uroporphyrinogen decarboxylase in the liver and red blood cells.

| porphyria cutanea tarda symptomatica | A form of hepatic porphyria (porphyria, hepatic) characterised by photosensitivity resulting in bullae that rupture easily to form shallow ulcers. This condition occurs in two forms: a sporadic, nonfamilial form that begins in middle age and has normal amounts of uroporphyrinogen decarboxylase with diminished activity in the liver; and a familial form in which there is an autosomal dominant inherited deficiency of uroporphyrinogen decarboxylase in the liver and red blood cells.

| porphyria hepatica | A category of porphyria that includes porphyria cutanea tarda, variegate porphyria, and coproporphyria. Synonym: porphyria hepatica. (05 Mar 2000) |
| porphyria, acute intermittent | A form of hepatic porphyria (porphyria, hepatic) characterised by periodic attacks of gastrointestinal disturbances, abdominal colic, paralyses, and psychiatric disorders. The onset of this condition is usually in the third or fourth decade of life. (12 Dec 1998) |
| porphyria, erythrohepatic | A form of porphyria characterised by a wide range of photocutaneous changes, liver disease, and an excess of protoporphyrin. (12 Dec 1998) |
| porphyria, erythropoietic | Autosomal recessive porphyria characterised by splenomegaly, photosensitivity, haemolytic anaemia, and the appearance of red urine in early infancy. This condition results from increased synthesis of uroporphyrinogen I relative to uroporphyrinogen III in bone marrow normoblasts. (12 Dec 1998) |
| porphyria, hepatic | Porphyria in which the liver is the site where excess formation of porphyrin or its precursors is found. Porphyria, acute intermittent and porphyria cutanea tarda are types of hepatic porphyria. (12 Dec 1998) |
| porphyrin | <protein> Porphyrins are pigments found in both animal and plant life. They are all chelates with metals (Fe, Mg, Co, Zn, Cu, Ni) and constituents of haemoglobin, chlorophyll, cytochromes. Increased levels of coproporphyrins can indicate congenital erythropoietic porphyria or sideroblastic anaemia. Increased protoporphyrins may be seen in infection, thalassaemia, sideroblastic anaemia, iron deficient anaemia, increased erythropoiesis and lead poisoning. Increased uroporphyrins may indicate congenital erythropoietic porphyria or erythropoietic protoporphyria. (27 Sep 1997) |

| PORT |
Port wine (also porto wine) is sweet, fortified wine from the Douro Valley in the northern part of Portugal; it takes its name from the city of Porto, the centre of port export and trading. Port has been made in Portugal since the mid 15th century. Port became very popular in England after the Methuen Treaty of 1703, when merchants were permitted to import it at a low duty, while war with France deprived English wine drinkers of French wine. ...
