The 35C1-NQR spectrum of several derivatives of chloral, Cl3CCHO, was studied in the ranee 77 K ^ T Tm. By use of the spin echo double resonance technique a relative assignment of the resonances to different ClaC-groups within one crystallized compound was possible. The solid compounds studied are: High temperature phase of chloral hydrate, Cl3CCH(OH)2; parachloral, (Cl3CCHO)3, (aand ß-isomer);...

"With reference to treatment, it will be noticed that ot the 83 cases, two absconded from the hospital, so that, practically, we have to deal with 81 instances of tetanus, and of these 13 are stated as having been " relieved" when discharged from hospital; this is doubtless a very unsatisfactory way of accounting for cases of tetanus, but it is unavoidable in this country ; the friends of the p...

The motility of Spirillum volutans is caused by the rotation of each polar flagellar fascicle in a direction opposite to that of the more slowly rotating cell. Both flagella form cones of revolution oriented in the same direction. When the cell reverses its motion, both fascicles simultaneously reverse their rotation and also the orientation of their cones of revolution, with the tail fascicle ...

Medium pressure UV is used for controlling the concentration of combined chlorine (chloramines) in many public swimming pools. Little is known about the fate of other disinfection by-products (DBPs) in UV treatment. Photolysis by medium pressure UV treatment was investigated for 12 DBPs reported to be found in swimming pool water: chloroform, bromodichloromethane, dibromochloromethane, bromofor...

A 6-year-old male child was scheduled for a dental procedure requiring conscious sedation. Prior to the procedure, the child was administered a dental cocktail containing chloral hydrate, hydroxyzine, and methadone. After returning from the dentist, the child appeared groggy and was allowed to sleep. A few hours later, he was found unresponsive, and following resuscitation attempts at a local m...

RATIONALE The aim of our study was to assess the changes in the fronto-parietal connectivity estimated by the cross approximate entropy (XAppEn) during noxious stimulation while under chloral hydrate anaesthesia, in rats. METHOD A group of 11 Wistar rats chronically implanted with Ni-Cr electrodes, which were placed on the dura mater of the right hemisphere (over the olfactory cortex, the fro...

1. Administration of dichloralphenazone, a complex of chloral hydrate and phenazone (antipyrine) caused a fall in steady-state plasma warfarin concentration and loss of anticoagulant control in five subjects. 2. This effect of dichloralphenazone is due to stimulation of the drug-oxidizing enzymes of the liver endoplasmic reticulum by antipyrine, the non-hypnotic part of the complex. Administrat...

The purpose of this study was to compare the effectiveness of triazolam to chloral hydrate with hydroxyzine when sedating young children for dental treatment. Twenty children, age 21 to 74 months, with a mean age of 44 months, were given triazolam. Twenty children, age 23 to 64 months, with a mean age of 42 months, were given chloral hydrate with hydroxyzine. The children were given an elixir o...
