| periodic acid | <chemical> Periodic acid (h5io6). A strong oxidizing agent. Chemical name: Periodic acid (H5IO6) (12 Dec 1998) |
| periodic acid Schiff reaction | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| periodic acid Schiff stain | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. Substances that can be demonstrated include carbohydrates, mucins, cartilage matrix, collagen, reticulum, basement membranes, fibrin, thyroid colloid, amyloid, glomerular hyaline deposits, and a number of other secretions or tissue constituents. Also used in for staining gels on which glycoproteins have been run. See: periodic acid Schiff reaction Synonym: PAS stain. (22 Sep 2002) |
| periodic arthralgia | A condition in which pain and swelling of one or more joints, most commonly the knee, occurs at regular intervals; there is sometimes abdominal pain, purpura, or oedema. Synonym: intermittent arthralgia. (05 Mar 2000) |
| periodic biopolymer | A biopolymer in which there are identical, repeating subunits. (05 Mar 2000) |
| periodic catatonia | Regularly reappearing phases of catatonic excitement. (05 Mar 2000) |
| periodic disease | A condition characterised by regularly recurring and intermittent episodes of fever, oedema, arthralgia, and gastric pain and vomiting, continuing for years without further development in otherwise healthy individuals. It is also called familial mediterranean fever. It does not refer to conditions in which episodes recur at regular intervals. (12 Dec 1998) |
| periodic fever | An obsolete term introduced to describe the intermittent febrile episodes seen in disease later recognised and named familial Mediterranean fever. (05 Mar 2000) |
| periodic filariasis | A form of filariasis in which microfilariae appear in the peripheral blood at regular 24-hr intervals; usually refers to the nocturnal periodicity of bancroftian filariasis. (05 Mar 2000) |
| periodic law | The properties of elements are periodical functions of their atomic weights; i.e., if the elements are arranged in the order of their atomic weights, every element in the series will be related in respect to its properties to the eighth in order before or after it. Synonym: periodic law. (05 Mar 2000) |
| periodic migrainous neuralgia | Recurrent facial pain and headache, more common in men than in women. Synonym: Harris' migraine. (05 Mar 2000) |
| periodic neutropenia | Neutropenia recurring at regular intervals (14 to 45 days), in association with various types of infectious diseases, e.g., stomatitis, cutaneous ulcers, furuncles, arthritis, and others. Synonym: cyclic neutropenia. (05 Mar 2000) |
| periodic oedema | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| periodic ophthalmia | An acute iridocyclitis of horses, involving one or both eyes; it subsides only to recur at intervals of varying length and usually ends in blindness; the cause is uncertain but some have associated it with leptospires; does not appear to be contagious. Synonym: moon blindness. (05 Mar 2000) |
| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
|---|---|
| paralysis, familial periodic | An autosomal dominant trait marked by recurring attacks of rapidly progressive flaccid paralysis. There are three types: I, associated with a fall in serum potassium levels (hypokalaemic periodic paralysis); II, associated with a rise therein (hyperkalaemic periodic paralysis, called also adynamia episodica hereditaria); and III, with normal levels (normokalaemic periodic paralysis). (12 Dec 1998) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| hyperkalaemic periodic paralysis | A form of periodic paralysis in which the serum potassium level is elevated during attacks; onset occurs in infancy, attacks are frequent but relatively mild, and myotonia is often present; autosomal dominant inheritance. (05 Mar 2000) |
| hypokalaemic periodic paralysis | <biochemistry> A rare inherited disorder, affecting men more often than women, characterised by intermittent episodes of muscle weakness or paralysis. One form, known as hypokalaemic periodic paralysis, is an autosomal recessive disorder that is characterised by bouts of muscle weakness (or paralysis) accompanied by low serum potassium levels. Inheritance: autosomal recessive. Incidence: 1 in 100,000. (11 Jan 1998) |
| sodium-responsive periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| normokalaemic periodic paralysis | A form of periodic paralysis in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance. Synonym: sodium-responsive periodic paralysis. (05 Mar 2000) |
| familial periodic paralysis | <neurology> A rare inherited disorder, affecting men more often than women, characterised by intermittent episodes of muscle weakness or paralysis. One form, known as hypokalaemic periodic paralysis, is an autosomal recessive disorder that is characterised by bouts of muscle weakness (or paralysis) accompanied by low serum potassium levels. Inheritance: autosomal recessive. Incidence: 1 in 100,000. (27 Sep 1997) |
