RESUMO
Disaccharides can be identified and determined quantitatively in fecal specimens by permethylation of the components in crude supernatants followed by isothermal gas chromatographic separation on OV-17 columns. The method provides a rapid screening procedure for detecting patients suspected of having a carbohydrate intolerance secondary to intestinal disaccharidase deficiency.

The effects of intra-osseous dental anaesthesia on heart rate and blood pressure was examined in 17 healthy volunteers. Adrenaline containing anaesthetic solutions were accompanied by increased heart rate and elevated systolic blood pressure which were not acceptable to a high proportion of subjects. Noradrenaline at the same concentration as adrenaline (1/80 000) usually decreased the heart rate and elevated the blood pressure. A few subjects experienced a feeling of weakness in the lower extremities when noradrenaline was injected. Endogenous catecholamine formation in these test conditions gave rise to insignificant circulatory effects.
