Production of carbon monoxide in cadavers.

Carbon monoxide (CO), total hemoglobin (Hb) and carboxyhemoglobin (HbCO) in the blood and reddish discolored body cavity fluids of cadavers which had not been exposed to fire and CO were analyzed. In 13 cadavers found on land, the maximum saturation of HbCO in the blood was 3.6%, and was 10.1% in the body cavity fluids. There was only one case in which the HbCO saturations in the body cavity fluids were more than 10%. In seven drowned bodies found in fresh water, the highest HbCO saturation in the blood was 6.1%, and was 44.1% in the body cavity fluids. There were three cases in which the HbCO saturations in the body cavity fluids were more than 10%. In 12 drowned bodies found in sea water, the HbCO saturations in the blood were not more than 6.2%, and the maximum saturation of HbCO in the body cavity fluids was 83.7%. There were eight cases in which the HbCO saturations in the body cavity fluids were more than 10%. The results seem to indicate that the interpretation of HbCO saturation in the blood would not be affected significantly by the postmortem formation of CO, and that body cavity fluids should not be used for CO determination.

Homicidal and camouflaged carbon monoxide poisoning in Japan.

There were 1,985 fatal cases of CO poisoning in the Tohoku district of Japan in the period from 1969 to 1980. Among them, 1,322 cases were suicidal, 662 accidental, and one homicidal, in which a man killed his wife with the self-made CO gas to obtain by fraud a large amount of life insurance. Our nationwide survey revealed four other cases of homicidal CO poisoning and two cases of camouflaged CO poisoning. The police and police surgeons should be cautious enough in cases of CO poisoning.

Physico-chemical properties and local toxic effects of injectables.

In Japan, many cases of muscle contracture as a sequela of injections have been reported. We studied the physico-chemical properties and muscle-damaging potential of many injectables which are commonly used in hospitals. Contrary to our expectations, the pH of the injectables was found to range widely from 1.4 to 12.8, and the osmotic ratio from 0.2 to 36. It was also found that their hemolytic potential was closely related to the severity of the muscle lesions in animal experiments and that there were many injectables with strong muscle-damaging potentials. Therefore, doctors should be informed of the physico-chemical properties and tissue-damaging potential of each injectable; pharmaceutical companies should exert all possible efforts to improve injectables; and doctors should keep the administration of intramuscular injections to a minimum and use them only in cases of actual need.

Transferrin (Tf) polymorphism: an analysis by isoelectric focusing.

The polymorphism of the transferrin (Tf) system was studied in a total of 300 unrelated Japanese individuals from Miyagi prefecture, the northern part of Japan using isoelectric focusing in thin-layer polyacrylamide gel. In our population samples three common phenotypes and nine variants were observed. The calculated allele frequencies were TfC1 = 0.773, TfC2 = 0.212, TfDchi (Chinese) = 0.008, and the combined frequencies for the TfBvar (variants) = 0.007. Family data (n = 44) were in accordance with an autosomal codominant fashion of inheritance. The use of isoelectric focusing procedure among Japanese will raise the probability of excluding a man falsely accused of paternity to 15.8% as compared with 1.5% when the conventional electrophoretic methods are used.
