KOMURA, S., UEDA, M. and FUJIMURA, K. Electroencephalographic Studies on Liquefied Petroleum Gas Poisoning in Rabbits. Tohoku J. exp. Med., 1973, 111 (1), 33-40 -Rabbits were put into a special box which had a gas-exit and an upperpositioned gas-inlet, from which the Japanese Industrial Standard No. 3 Liquefied Petroleum Gas (L.P.G.) was distributed on equal proportion. The changes in the behavior were noted as follows: Initially, licking and sniffing appeared, and at about one hour later when the L.P.G. concentration reached approximately 30%, the walking got difficult, and occasional screaming were heard as the sign of stimulation. At about 100 minutes later, namely at approxi mately 60% L.P.G. concentration, temporary nystagmus appeared. After that, the muscles were hypotonic, and an excessive salivation was noted. The E.C.G. changes were as follows: With the initial sending in of L.P.G., the pulse rate increased gradually until about the 2 hours' peak-point after which it decreased again being accompanied with S-T depression and inverted T wave, clearly indicating the presence of some cardiac damage. The neocortex showed a

Ataxia with Parkinsonism and dystonia after intentional inhalation of liquefied petroleum gas
The practice of inhaling liquefied petroleum gas (LPG) to commit suicide is uncommon and almost exclusively a prerogative of the prison population. Numerous cases of sudden deaths caused by intentional propane and/or butane inhalation have been described, but these cases survived and a description of the consequences is very rare. We describe a prisoner who survived after voluntary inhalation o...

Four Lump Kinetics Models to Describe the Aromatization Reactions of Liquefied Petroleum Gas
The aromatization reaction of liquefied petroleum gas has been studied by using three liquefied petroleum gases as raw material and LBO-A as catalyst, and four lump kinetics models networks have been put up on the basis of lump theory and the aromatization reaction mechanism. In the network the aromatization reaction species was firstly lumped into C 4 , propylene, low molecule hydrocarbon, liq...
متن کاملAutothermal Reforming Catalysts For Use In Fuel Processors For Automotive And Stationary H2 Production
Introduction Reforming (i.e., partial oxidation, steam reforming, or autothermal reforming (ATR)) of infrastructure fuels, such as natural gas, liquefied petroleum gas, gasoline, or diesel, is one approach being investigated for distributed H2 production for use with fuel cell systems being developed for automotive and stationary applications. One area of interest is reforming gasoline either o...
متن کاملRecording acute poisoning deaths.
Recording deaths from acute poisoning/substance abuse is not straightforward. The International Classification of Diseases (ICD), used to code mortality statistics, is aimed towards recording the underlying cause of death such as suicide or drug dependence rather than gathering data on poisoning per se. Despite the inherent difficulties clear trends can be observed from the data available for E...
