[Carbohydrate metabolism in hypokalemic periodic paralysis (a clinico-histochemical study)]. 1976

R I Antipova

The author presets some data on histochemical studies of muscle carbohydrate metabolism in patients with hypopotassemic periodic paralysis during the attack and in intermissions. The most constant and considerable changes were revealed during the paralytic attack and they lead to a decrease of phosphorylase activity, an increase of glycogen content and glucose decrease in the muscular fibers. In intermissions these changes were expressed either minimally or were absent altogether. The initial biochemical effect remains unknown. Undoubtedly, the carbohydrate metabolism is significantly damaged in this disease, and there is a definite parallelism between the severity of the clinical course and the degree of the revealed histochemical changes in the muscles.

UI	MeSH Term	Description	Entries
D007008	Hypokalemia	Abnormally low potassium concentration in the blood. It may result from potassium loss by renal secretion or by the gastrointestinal route, as by vomiting or diarrhea. It may be manifested clinically by neuromuscular disorders ranging from weakness to paralysis, by electrocardiographic abnormalities (depression of the T wave and elevation of the U wave), by renal disease, and by gastrointestinal disorders.

D007770	L-Lactate Dehydrogenase	A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.	Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase

D010243	Paralysis	A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function.

D010245	Paralyses, Familial Periodic	A heterogenous group of inherited disorders characterized by recurring attacks of rapidly progressive flaccid paralysis or myotonia. These conditions have in common a mutation of the gene encoding the alpha subunit of the sodium channel in skeletal muscle. They are frequently associated with fluctuations in serum potassium levels. Periodic paralysis may also occur as a non-familial process secondary to THYROTOXICOSIS and other conditions.

D010507	Periodicity	The tendency of a phenomenon to recur at regular intervals; in biological systems, the recurrence of certain activities (including hormonal, cellular, neural) may be annual, seasonal, monthly, daily, or more frequently (ultradian).

D005634	Fructose-Bisphosphate Aldolase	An enzyme of the lyase class that catalyzes the cleavage of fructose 1,6-biphosphate to form dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. The enzyme also acts on (3S,4R)-ketose 1-phosphates. The yeast and bacterial enzymes are zinc proteins. (Enzyme Nomenclature, 1992) E.C. 4.1.2.13.
