The subject of histamine release was investigated in 16 volunteers by means of plasma histamine determination after the administration of etomidate, Althesin, propanidid, and Cremophor EL. Althesin and propanidid caused release of histamine in various degrees of frequency. Blood pressure changes were rather pronounced with both anaesthetic agents; tachycardia reached its mavimiim in the first a...

CT1341 is a new intravenous anaesthetic which appears to have overcome the disadvantages of the earlier steroid. The formulation is a mixture of two closely related steroids with Cremophor EL and the optimum dose for induction is 50-60 (J/kg though much larger doses can be given without serious side effects. As the dose is increased the incidence of muscle movements, respiratory depression and ...

This paper investigates the kinetics of structure H (sH) formation kinetics above and below the structure I (sI) formation equilibrium curve at temperatures of between 2°C and 6°C. Methane was used as a help gas and methylcyclohexane (MCH) was used as sH former. It was concluded that in the points above the sI formation equilibrium curve, at the first, the sI forms, and then converts to sH be...

To test whether larval selectivity at settlement contributes to distributional patterns of benthic infauna, we conducted three reciprocal sediment transplant experiments at 15-m-deep coarse-sand and muddy-sand sites (;3 km apart) on the continental shelf near Tuckerton, New Jersey. During 3to 5-d deployments in 1994, larvae of the surfclam, Spisula solidissima, selected coarse sand over muddy s...
