Comparative effects of copper, cadmium and mercury on tissue glycogen of the catfish, Heteropneustes fossils (Bloch). 1982

D K Srivastava

Copper (Cu), cadmium (Cd) and mercury (Hg) at concentrations of 12.5 mg/l, caused a decline in the glycogen level of liver, muscle, brain and kidney of Heteropneustes fossilis. A significant increase in the glycogen content of brain was caused by low concentrations (5 and 7.5 mg/l) of both Cd and Hg 5 mg/l Cu raised the kidney glycogen level, while the same dose of Hg raised liver glycogen. It is suggested that heavy metals in low concentrations act through the endocrine system, creating hormone and/or enzyme imbalance.

UI	MeSH Term	Description	Entries
D008628	Mercury	A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
D008670	Metals	Electropositive chemical elements characterized by ductility, malleability, luster, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. (Grant & Hackh's Chemical Dictionary, 5th ed)	Metal
D002104	Cadmium	An element with atomic symbol Cd, atomic number 48, and atomic weight 112.41. It is a metal and ingestion will lead to CADMIUM POISONING.
D003300	Copper	A heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55.	Copper-63,Copper 63
