Determination of the distribution of conduction velocities in workers exposed to lead, zinc, and copper.
By measuring the distribution of conduction velocities (DCV) in sensory fibres of the median nerve, the effects of asymptomatic increased lead, zinc, and copper absorption on the conduction velocities of slower and faster nerve fibres were examined in 29 gun metal founders with blood lead (BPb) concentrations of 22-59 (mean 39) micrograms/dl (1.1-2.8 (mean 1.9) mumol/l). The results indicated t...
متن کاملAn experimental study on nerve conduction velocities and biochemical parameters in lead-administered rats.
An experimental study was carried out to clarify the relationships between lead exposure and the changes in nerve conduction velocities or in porphyrin metabolism in rats. The rats in Groups A, B and C received intraperitoneal lead injections in respective doses of 0, 0.2 and 2.0 mg/kg of lead, once a week for 22 weeks. During the experiment, all rats grew normally, and there was no significant...
متن کاملBlood lead and haemoglobin in lead absorption.
a low haemoglobin but none had symptoms or signs that were likely to be due to lead absorption. A further i8 men had haemoglobins of 89% (13 g./Ioo ml.) or less. None was thought to be low due to lead absorption. The absence of symptoms, signs, and low haemoglobins in association with relatively high blood leads is unlikely to be due to errors in blood lead or haemoglobin estimation. Alternativ...
متن کاملThe Relationship between Blood Lead Level and Neuro-psychological and Hematological Findings in Lead-Exposed Workers of Battery Industry
Background: Hematological effects and digestive and neuro-psychological signs and symptoms are some manifestations of lead toxicity. However, there are conflicting reports of their prevalence among lead exposed workers and their relationship with blood lead levels (BLL). This case- control study assessed the relationship between BLL and hematological indexes and digestive (abdominal colic, ir...
متن کاملCumulative blood lead levels and nerve conduction parameters.
Most studies on the effects of lead on the peripheral nerves used "current' blood lead levels of the workers and infer the nerve conduction's findings to it. This practice is not ideal as the toxicity of lead on the peripheral nerves occurs over a period of time. Seventy-two workers in a lead battery manufacturing factory and 82 referents were studied with the aim of (1) correlating the nerve c...
