The objective of this study was to investigate the effect of occupational exposure to carbon disulphide (CS2) on the total cholesterol, blood pressure and prevalence of coronary heart disease (CHD). A cross-sectional study involving 252 viscose rayon workers and 252 age and sex matched controls was carried out. Depending on the job and specific work place, the CS2 concentrations were between 10...

Effects of carbon disulphide (CS2) on conduction velocity in sciatic and tibial nerve were investigated in rats exposed to CS2 vapour at concentrations of 0.9 mg/l or 1.6 mg/l of air for periods of 1.5, 3, 6, 9 and 12 months. The conduction velocity was measured on the day following each exposure period, and again, three and six months after the last day of exposure. The majority of exposed rat...

OBJECTIVES To understand the prevalence of polyneuropathy and correlations among the clinical manifestations, electrophysiological findings, and degree of exposure to carbon disulphide (CS2) in workers who were exposed to variable concentrations of CS2 in a viscose rayon factory. METHODS All the 163 workers received a detailed physical and neurological evaluation. Fixed point air samples were...

Paired associative stimulation (PAS) of the motor cortex leads to increased motor evoked potential (MEP) amplitudes in the stimulated hand muscles. We hypothesized that evoking GABA(A) receptor-mediated short-interval intracortical inhibition (SICI) simultaneously with excitatory PAS would depress long-term potentiation plasticity in motor cortex. Four different PAS paradigms were tested, stand...

The ability of microorganisms to grow on carbon disulphide (CS,) as a sole source of carbon and energy appears to be very limited : none was obtained from enrichment culture and eight Thiobacillus species could not use it. Thiobacillus thioparus strain TK-m could grow autotrophically on either CS2 or carbonyl sulphide (COS) as sole substrates. Growth yield on CS2 was 7.9 f 0.9 g cell-carbon (mo...

HIV infection increases the burden of disease of malaria in pregnancy, in part by impairing the development of immunity. We measured total IgG and phagocytic antibodies against variant surface antigens of placental-type CS2 parasites in 187 secundigravidae (65% HIV infected). In women with placental malaria infection, phagocytic antibodies to CS2(VSA) were decreased in the presence of HIV (p = ...

Carbon disulfide (CS2) intoxication may induce peripheral neuropathy, encephalopathy, and cardiovascular diseases. In our studies, abnormalities of the peripheral nerves including clinical symptoms and electrophysiological findings were still present 3 years after cessation of CS2 exposure. The data indicate that CS2 neuropathy may persist for a period of time. The involvement of central nervou...

Biofiltration of industrial carbon disulfide (CS2)-contaminated waste air streams results in the acidification of biofilters and therefore reduced performance, high water use, and increased costs. To address these issues, we isolated 16 extremely acidophilic CS2-converting Acidithiobacillus thiooxidans strains that tolerated up to 6% (vol/vol) sulfuric acid. The ecophysiological properties of f...

An analysis of the molecular dynamics (МD) of the interaction between a carbon nanotube (CNT) and a carbon disulfide active solvent (CS2) has been carried out. The aim of the present work is to estimate the dynamical and structural behavior of the CNT-CS2 system at different relative atomic concentrations and under temperature changes. The structural radial distribution functions and the dynami...

OBJECTIVES We conducted a 6-year cohort study to evaluate the relationship between carbon disulfide (CS2) exposure and reductions in the motor and sensory nerve conduction velocity (MCV and SCV) of the median nerve. METHODS Study subjects at baseline included 432 exposed workers and 402 unexposed workers. Among the exposed workers, 145 workers terminated CS2 exposure during the follow-up peri...
