ABSTRACT

OBJECTIVE: To evaluate the cytogenetic effects following the ingestion of high doses of arsenicals. METHODS: Determination of the mean sister chromatid exchange (SCE) frequency and the population of high-frequency cells (HFC, cells with a high SCE frequency) in the peripheral blood lymphocytes in four patients who ingested 150 mg KAsO2, 1 g, 10 g and 20 g As2O3 respectively. RESULTS: Doses of 10 g and 20 g significantly increased the HFC frequency and produced a shift in the distribution of the cells in accordance with the number of SCEs. The mean frequency of SCEs/cell was affected only after the highest dose (20 g). CONCLUSION: These results strongly suggest that cytogenetic methods are inappropriate for biomonitoring people occupationally exposed to arsenicals.

ABSTRACT

The latex of pokok ipoh (Antiaris toxocaria) and the root bark of akar ipoh (Strychnos species) have been the main sources of the poisonous principles in dart and arrow poisons prepared throughout south-east Asia. We report a fatal case of rhabdomyolysis and acute oliguric renal failure following oral ingestion of blowpipe dart poison. To our knowledge this is the first such report.

ABSTRACT

Strychnine poisoning of 36 dunlin (Calidris alpina) and two killdeer (Charadrius vociferus) in Yolo County, California (USA) was documented from 11 to 17 December 1990. Birds were found dead on a field containing treated wheat seeds (337 micrograms strychnine/g seed) in postures consistent with the known physiopathology of strychnine poisoning: rapid rigor mortis, wings folded over backs, straightened toes, and fecal material extruding from vents. Five dunlin and two killdeer were necropsied, and their crop and stomach contents were analyzed by high performance liquid chromatography for the presence of strychnine. The mean (+/- SD) actual unabsorbed strychnine concentration per amount stomach content for the five dunlin was 110 (+/- 108) micrograms/g and for the two killdeer, 210 (+/- 109) micrograms/g. Shorebirds have not been identified previously as victims of pesticides.

ABSTRACT

O número de acidentes tóxicos e por animais peçonhentos atendidos pelo CIAVE-BA tem aumentado a cada ano. De 1983 a 1986 foram atendidoos 11.075 pacientes, correspondendo a 2.133 e 1983, 2.335 em 1984, 2.967 em 1985, 3.640 em 1986 e 1.924 no primeiro semestre de 1987, predominado em primeiro lugar de incidência os acidentes por animais peçonhentos. Considerando as intoxicaçöes por agentes químicos, plantas e alimentos, o maior número de intoxicaçöes foi devido aos medicamentos, em segundo lugar aos praguicidas, incluindo os raticidas, e em 3§ lugar aos domissanitários. O número total de atendimento por praguicidas de 1983 até o primeiro semestre de 1987 foi de 1.024 casos e de raticidas 360. Entre os acidentes ocorridos com praguicidas de uso agrícola, os inseticidas organoclorados foram os que mais causaram intoxicaçöes em 1983, 1984, 1986 e 1987; em segundo lugar ficaram os inseticidas organofosforados e em 3§ lugar os fungicidas e herbicidas. No ano de 1986 o primeiro lugar foi ocupado pelos organofosforados, o 2§ pelos organoclorados e o 3§ pelos fungicidas e herbicidas. É importante se destacar que após a proibiçäo do uso agícola dos inseticidas organoclorados a incidência de intoxicaçöes por organofosforados tem aumentado consideravelmente, correspondendo em 1984 a 10,5% das intoxicaçöes totais por praguicidas, em 1985 a 12,6% em 1986 a 29,3% e em 1987 a 30,3%. Se considerarmos as intoxicaçöes causadas por todos os grupos de preguicidas, exceto os raticidas, vamos verificar que o primeiro lugar, de 1983 a 1986, se deve aos compostos de uso domésticos, representados principalmente pelos inseticidas organofosforados, carbamatos e piretróides, seguidos pelos praguicidas de uso agrícola na mesma sequência vista anteriormente. Em 1987, em primeiro lugar encontramos as intoxicaçöes por organoclorados, em 2§ por organofosforados, em 3§ pelos praguicidas de uso doméstico e em 4§ por fungicidas e herbicidas
