Lead intoxication is accompanied by an acquired deficiency of erythrocyte pryimidine-specific, 5'-nucleotidase. Genetically determined deficiency of this enzyme is associated with chronic hemolysis, marked basophilic stippling of erythrocytes on stained blood films, and unique intraerythrocytic accumulations of pyrimidine-containing nucleotides. The present report documents that lead-induced de...

The long-term effects of low-level lead intoxication are not known. The sympathetic skin response (SSR) was evaluated in a group of 60 former workers of a primary lead smelter, located in Santo Amaro, BA, Brazil. The individuals participating in the study were submitted to a clinical-epidemiological evaluation including questions related to potential risk factors for intoxication, complaints re...

Various studies have shown the important interrelationship between dietary nutrients and the toxicity of heavy metals. Antagonism or synergism may occur between lead (Pb) and nutritional factors at the sites of absorption or at the sites of effects. A diet low in protein, minerals and certain vitamins may not only enhance the circulating dose of Pb but may also reduce the general health status,...

Lead Intoxication — Continued In December 1991, a venous blood lead level (BLL) of 50 μg/dL was detected in a 46-year-old Ohio man during a routine pre-employment examination. He was referred to a university-based pharmacology and toxicology clinic for further evaluation; clinic physicians investigated the case. Although a repeat BLL obtained 1 month later was 51 μg/dL, he reported no exposure ...

Lead poisoning and acute intermittent porphyria (AIP) may exhibit similar neurologic manifestations, and they have in common elevated excretion of urinary aminolevulinic acid (ALA). Despite their similarities, the possible pathophysiologic connection between AIP and lead poisoning in not known. Because intravenous hematin administration has produced biochemical improvement in AIP, a hematin tri...

Lead acetate was administered to adult New Zealand White rabbits in their drinking water. Their mean blood lead level rose to 4.5 mumol/l within a week and then remained relatively constant. The rabbits developed a marked coproporphyrinuria. Plasma levels of coproporphyrin increased but not in proportion to the urine excretion. Thus the renal clearance of coproporphyrin rose from a mean of 1.8 ...

Intoxication is still the major cause of morbidity and mortality worldwide. Despite growing number global studies about intoxication, comprehensive bibliometric are not available in literature. This study aims to analyze scientific articles intoxication/poisoning evaluate this subject matter from a holistic point view. Studies intoxication that were published years between 1975 2020 downloaded ...

Although population exposure to lead has declined, chronic lead toxicity remains a major public health problem in the United States affecting millions of children and adults. Important gaps exist in knowledge of the pathophysiology of chronic lead intoxication. These gaps have impeded development of control strategies. To close current gaps in knowledge of chronic lead toxicity, we propose an i...

BACKGROUND Expanding lead-based bullets, commonly used for hunting of big game, produce a scattering of lead particles in the carcass around the wound channel. Trimmings around this channel, which are sometimes fed to dogs, may contain lead particles. The aim of this study was to assess potential health effects of feeding dogs such trimmings. RESULTS Lead ingestion most commonly causes gastro...
