Efficacy of Allicin in Decreasing Lead (Pb) Accumulation in Selected Tissues of Lead-Exposed Common Carp (Cyprinus carpio).
Summary of "Efficacy of Allicin in Decreasing Lead (Pb) Accumulation in Selected Tissues of Lead-Exposed Common Carp (Cyprinus carpio)."
The objective of this study was to evaluate the effects of allicin, the main biologically active component of garlic clove extracts, on lead levels in different common carp tissues including liver, kidney, brain, bone, and blood following experimental lead poisoning. Fish were divided randomly into five groups depending on the combination of lead acetate and allicin treatments. Lead acetate exposure (7.0 mgL(-1), 10 days) caused a significant increase in mean Pb concentrations in all examined tissues in comparison to control unexposed fish (p < 0. 001). The results showed that allicin supplementation is effective in decreasing lead accumulation in all examined tissues of common carp. The promising ameliorative effects of allicin on tissue lead levels of common carp make it a good candidate for therapeutic intervention of lead poisoning. However, more studies are required to elucidate the pharmacokinetic effects of allicin and also molecular basis of the ameliorative properties of allicin in lead poisoning.

Medical and Biotech [MESH] Definitions
Lead Poisoning, Nervous System
Injury to the nervous system secondary to exposure to lead compounds. Two distinct clinical patterns occur in children (LEAD POISONING, NERVOUS SYSTEM, CHILDHOOD) and adults (LEAD POISONING, NERVOUS SYSTEM, ADULT). In children, lead poisoning typically produces an encephalopathy. In adults, exposure to toxic levels of lead is associated with a peripheral neuropathy.
Unstable isotopes of lead that decay or disintegrate emitting radiation. Pb atoms with atomic weights 194-203, 205, and 209-214 are radioactive lead isotopes.
Lead Poisoning, Nervous System, Childhood
Neurologic disorders occurring in children following lead exposure. The most frequent manifestation of childhood lead toxicity is an encephalopathy associated with chronic ingestion of lead that usually presents between the ages of 1 and 3 years. Clinical manifestations include behavioral changes followed by lethargy; CONVULSIONS; HALLUCINATIONS; DELIRIUM; ATAXIA; and vomiting. Elevated intracranial pressure (HYPERTENSION, INTRACRANIAL) and CEREBRAL EDEMA may occur. (From Adams et al., Principles of Neurology, 6th ed, p1210-2)
Lead Poisoning, Nervous System, Adult
Neurologic conditions in adults associated with acute or chronic exposure to lead or any of its salts. The most common lead related neurologic syndrome in adults consists of a polyneuropathy involving motor fibers. This tends to affect distal nerves and may present as wrist drop due to RADIAL NEUROPATHY. Additional features of chronic lead exposure include ANEMIA; CONSTIPATION; colicky abdominal pain; a bluish lead line of the gums; interstitial nephritis (NEPHRITIS, INTERSTITIAL); and saturnine gout. An encephalopathy may rarely occur. (From Adams et al., Principles of Neurology, 6th ed, p1212)
