Determination of the aryltetralin lignan content of podophyllum resins and roots/rhizomes.

A simple, quantitatively reproducible method for determining the aryltetralin lignan content of the resins and roots/rhizomes of Podophyllum hexandrum and P. peltatum is described. The method confirms that P. hexandrum resins and roots/rhizomes contain approximately four times the quantity of lignans as do those of P. peltatum and also that there is a significant variation in the lignan content of P. hexandrum resins.

Changes in plasma catecholamine concentrations during endotracheal intubation.

The changes in arterial pressure and arterial concentrations of noradrenaline, adrenaline and dopamine were monitored in 16 patients undergoing endotracheal intubation. Significant increases in mean arterial pressure and plasma noradrenaline were noted. The increases in arterial pressure were associated with increases in noradrenaline concentrations. Adrenaline and dopamine concentrations did not change significantly following intubation. The results suggest a predominantly sympathetic response during intubation and the need for prophylaxis in patients at risk.
