[Reference values for carboxyhemoglobin].
INTRODUCTION The reference values (RV) of biological indicators are used in the interpretation of the results of such indicators in individuals occupationally exposed to chemical agents. The Brazilian Group for the Establishment of Reference Values has worked on these definitions for the purpose of establishing RVs for several bioindicators in various regions of the country. In the present stud...
متن کاملSimplified determination of carboxyhemoglobin.
This spectrophotometric method for estimating carboxyhemoglobin is based on the production of a two-pigment mixture by reducing oxyhemoglobin and methemoglobin with sodium hydrosulfite . Absorbances of the pigment are measured at 420 and 432 nm. Protecting the solutions against exposure to air is unnecessary. Values are stable and reproducible when the solutions are buffered at pH 6.85.
متن کاملThe spectrophotometric measurement of carboxyhemoglobin.
A simple, reliable and rapid method for the spectrophotometric determina tion of carboxyhemoglobin in fresh blood is described. A blood hemolysate is prepared by diluting a blood sample with 0.4 percent NH4 OH. Addition of sodium dithionite deoxygenates hemoglobin (and reduces methemoglobin if present) without affecting carboxyhemoglobin. Comparison of the 541/555 nm absorbance ratio for the h...
متن کاملToxicokinetics and Metabolism
In this study, the dermal penetration rate of carbofuran, carbosulfan, and furathiocarb has been measured with rat abdominal skin using the static diffusion cell. The technical grades of three compounds were applied at different doses on skin surface mounted in static diffusion cell and incubated at 32 C for 48 h with shaking. The same procedures were carried out with furathiocarb EC (emulsifia...
متن کاملToxicokinetics of Kava
Kava is traditionally consumed by South Pacific islanders as a drink and became popular in Western society as a supplement for anxiety and insomnia. Kava extracts are generally well tolerated, but reports of hepatotoxicity necessitated an international reappraisal of its safety. Hepatotoxicity can occur as an acute, severe form or a chronic, mild form. Inflammation appears to be involved in bot...
