Lead Studies
It appears, from the investigations in other laboratories, that the anemia observed in cases of lead poisoning is due to destruction of blood rather than to diminished production of blood. The method of poisoning cells in vitro with lead was adopted in order to study this phenomenon, and distinct effects were thereby obtained, even when only 0.001 mg. of lead is added to approximately 5 billion...
متن کاملNeuropsychological studies on lead workers in Singapore.
The neuropsychological performance of a group of 49 workers occupationally exposed to lead was compared with a matched control group of 36 non-exposed workers. The psychometric measurements were composed of tests covering a broad range of different neuropsychological functions, particular emphasis being given to perceptual motor ability and attention concentration functioning. A questionnaire t...
متن کاملNeurophysiological studies on workers exposed to lead.
Nerve conduction and somatosensory evoked potential studies were undertaken on 46 workers exposed to a combination of organic and inorganic lead. In addition electroencephalograms were carried out on 20 of the workers; the results were compared with those obtained for workers not exposed to lead. The workers exposed to lead had a mean blood lead concentration of 2.35 mumol/l (48.7 micrograms/10...
متن کاملPopulation studies on Gilbert's syndrome.
Total serum bilirubin concentration was measured by an Autoanalyzer technique in 197 normal males and 102 normal females. The mean bilirubin concentration was significantly lower in the females than in the males. Total bilirubin concentration in the males showed a bimodal distribution with an antimode at 24 mumol/1 (1.4 mg/100ml). Individuals with bilirubin concentration above this value had un...
متن کاملPopulation structure and mating-type genes of Colletotrichum graminicola from Agrostis palustris.
Eighty-seven isolates of Colletotrichum graminicola, mostly from Agrostis palustris, were collected in grass fields, most of which were in Ontario, Canada. Specific primers were designed to amplify the mating-type (MAT) genes and, among 35 isolates tested, all yielded a band of the expected size for MAT2. For six isolates, the MAT2 PCR products were sequenced and found to be similar to that rep...
