October. 196 A case report is given of a young boy who suffered acutely disturbing hallucinatory symptoms after voluntarily sniffing petrol vapors. A total of 15 other cases of such voluntary breathing of petrol fumes, and similar hallucinatory experiences are noted in the literature.-- APCAA1 986 Pneumatocele Formation Complicating Hydrocarbon Pneumonitis. O. Baghdassarian and S. Weiner. Am. J. Roentgenol. Radium Therapy Nuclear Med. 95, 104-110 (Sept. 1965). Ingestion of petroleum distillates accounts for 21 to 25% of all fatal poisonings in children und the age of five years. Between 1951 and 1958, 763 deaths in the United States were attributed hydrocarbon ingestion; 90% of these were in children under five years of age. Complications resulting from ingestion of petroleum distillates include central nervous system depression, degenerative and hemorrhagic changes in various viscera, and pneumonitis. Pneumonia and pulmonary edema are the greatest threats to life. Three patients who developed pneumatocele following hydrocarbon pneumonia are reported. AU threee progressed to complete recovery without evidence of superimposed infection or additional complication.--Am. Rev. Resp.

Food Sci. 30, 1037-1042 (Nov.-Dec. 1965). Concentrations of ethylene chlorohydrin up to about 1,000 ppm were found in whole spices and ground spice mixtures after commercial fumigation with ethylene oxide. These chlorohydrins are persistent under food processing conditions. There are 16 references. -- Public Health Eng.

In three patients with aplastic anemia due to chronic benzene poisoning, osmotic fragility was tested before and after incubation, at 37" C. (98. 6 F.) for 24 hours. Slight to moderate increa after incubation were observed in two patients, whereas in all cases the osmotic fragility was within normal range before incubation. -- J. Am. Med. Assn.

Deuterium intoxication was studied in three groups of animals that ingested 75% deuterium oxit drinking water. In one group, four pregnant rats were given deuterium, beginning the tenth da of gestation. Histological study revealed areas of pyknotic nuclei in the renal tubules and base ment membrane thickening of salivary gland acini. Another group given deuterium starting the 15th day of gestation was sacrificed five days later. An electron microscopic study showed an increase of large vacuoles and electron-dense cytoplasmic bodies in the cells of the proximal convoluted tubule. Enlargement of the endothelial and epithelial glomerular cells resulted in partial obliteration of capillary lumina. Degradation of the endoplasmic structures was observ in the cells of the salivary gland acini. In the third group, two mice received deuterium for ni: to ten days. Alterations were more pronounced, with varying degrees of degeneration present in the cells of the proximal convoluted tubules. Deuterium may have an effect on water transfe -- J. Am. Med. Assn.

Acad. Sci. J_32, 274-287 (Dec. 31, 1965). The impinger method was developed for the evaluation of atmospheres in silicosis producing occupations. The impinger is an efficient collector of quartz and particles of a similar density 17.
