Copper is a persistent toxic and bio-accumulative heavy metal of global concern. Continuous exposure of copper compounds of different origin is the most common form of copper poisoning and in turn adversely altering testis morphology and function and affecting sperm quality. L-carnitine has a vital role in the spermatogenesis, physiology of sperm, sperm production and quality. This study was designed to examine whether the detrimental effects of long-term copper consumption on sperm quality and testis function of Wistar albino rat could be prevented by L-carnitine therapy...

Traditional Chinese herbal medicine is widely used for primary health care worldwide as it mostly consists of herbs or herbal extracts known to be safe. However, owing to the intentional or unintentional addition to herbs of lead-containing bases or pastes, lead poisoning from traditional Chinese medicine (TCM) remains a serious issue. We report here a case of lead poisoning caused by long-term use of homemade TCM. A 66-year-old man was admitted for periumbilical pain and constipation. A detailed medication history revealed that the patient had been using homemade TCM for the past 8 months...

Lead is a heavy metal that remains a persistent environmental toxin. Although there have been a substantial number of reviews published on the health effects of lead, these reviews have predominantly focused on recent publications and rarely look at older, more historical articles. Old documents on lead can provide useful insight in establishing the historical context of lead usage and its modes of toxicity. The objective of this review is to explore historical understandings and uses of lead prior to the 20th century...

Kavitha Subramanian Vignesh, George S Deepe
Metallothioneins (MTs) are a family of metal-binding proteins virtually expressed in all organisms including prokaryotes, lower eukaryotes, invertebrates and mammals. These proteins regulate homeostasis of zinc (Zn) and copper (Cu), mitigate heavy metal poisoning, and alleviate superoxide stress. In recent years, MTs have emerged as an important, yet largely underappreciated, component of the immune system. Innate and adaptive immune cells regulate MTs in response to stress stimuli, cytokine signals and microbial challenge...

This article reviews the clinical use of the metal chelators sodium 2,3-dimercapto-1-propanesulfonate (DMPS), meso-2,3-dimercaptosuccinic acid (DMSA), and calcium disodium edetate (CaEDTA, calcium EDTA) in overexposure and poisonings with salts of lead (Pb), mercury (Hg), and arsenic (As). DMSA has considerably lower toxicity than the classic heavy metal antagonist BAL (2,3-dimercaptopropanol) and is also less toxic than DMPS. Because of its adverse effects, CaEDTA should be replaced by DMSA as the antidote of choice in treating moderate Pb poisoning...

Many herbal products are harmless or possess minimal toxicity, whereas, some contain toxic ingredients that may not be identified due to lack of quality control or not listed on the label. Over the years, several case reports and studies have documented that herbal medications may contain ingredients that are toxic. Several studies have documented that some herbal medications contained high concentrations of heavy metals, such as lead, mercury, and arsenic. Publications of such case reports and studies have repeatedly reminded us that we have failed in our legal and civic duties of educating users of herbal medications and general population about the grave concerns posed by the herbal medications and their associated toxicities...

Cadmium (Cd) is a highly toxic heavy metal that can affect human and animal health. Selenium (Se) is an essential microelement that can protect various organs against toxic heavy metals. Although many studies have investigated the adverse effect of Cd in rats and several other animals, little is known regarding the mechanisms of Cd-induced autophagy in the chicken pancreas and the antagonistic effect of Se on Cd. In the current study, we fed chickens Se, Cd, or Se and Cd supplements to establish the Se and Cd interaction model and to measure the concentrations of Se and Cd in the chicken pancreas...

Medicinal plants accumulate heavy metals from contaminated soil, and their consumption can cause poisoning. Our objective was to determine the levels of Pb, Cd, Zn, Cu, Fe, and Mn in four medicinal plant species (Achillea millefolium, Hypericum perforatum, Plantago lanceolata, and Urtica dioica) and their native soil, all sampled at a former smelter. The highest soil Cd, Pb, and Zn levels surpassed the maximum allowed limit 75-fold, 48-fold, and 14-fold, respectively. Their soil levels correlated with those in the plants, but this was not the case with Cu, Fe, and Mn...

Cadmium is a highly poisonous metal and a human carcinogen, but the molecular mechanisms underlying its cellular toxicity are not fully understood. Recent findings in yeast cells indicate that cadmium exerts its deleterious effects by inducing widespread misfolding and aggregation of nascent proteins. Here, we discuss this novel mode of toxic heavy metal action and propose a mechanism by which molecular chaperones may reduce the damaging effects of heavy metal ions on protein structures.

The outbreak of itai-itai disease, which is the most severe stage of chronic cadmium poisoning, has occurred in the cadmium-polluted Jinzu River basin in Toyama. In this area, the river was contaminated by slags from a mine upstream; consequently, the soil in rice paddies became polluted with heavy metals including cadmium through irrigation water streams from around 1910 to the 1960s. The inhabitants of the Jinzu River basin used the river water for drinking and cooking until around 1960. In this paper, we review the geographical features of the Jinzu River basin and the endemic area of itai-itai disease, and reevaluated the studies conducted in 1970's by the Toyama Institute of Health, because these studies have revealed a clear relationship between renal dysfunction or occurrence of itai-itai disease and exposure to cadmium through irrigation water streams...

Cadmium (Cd) and lead (Pb) are toxic elements that accumulate to the largest extent in bones. Rats were used to investigate whether tannic acid (TA; 0.5%, 1.0%, 1.5%. 2.0%, or 2.5%) would have a protective effect on the structure and properties of bones in the case of exposure to Cd and Pb (diet: 7 mg Cd/kg and 50 mg Pb/kg) for 6 weeks. The effects of administration of TA in Cd- and Pb-poisoned rats on bone characteristics and the morphology of articular and growth cartilages were determined. All the rats administered Cd and Pb had an enhanced Cd and Pb concentration in blood plasma and bone and reduced bone Ca content irrespective of the TA administration...

In light of the recent lead contamination of the water in Flint, Michigan and its potential adverse outcomes, much research and media attention has turned towards the safety profile of commonly used chelators. Dimercapto-1-propanesulfonic acid (DMPS) typically used in the treatment of lead, mercury and arsenic poisoning also displays a high affinity towards transition metals such as zinc and copper, essential for biological functioning. It is given in series of dosages (0.2-0.4g/day) over a long period, and has the ability to enter cells...
