Effect of injection

The modern usage of P2" go Asts for the treatment of asthma dates to 1903 when the effect of injected epinephrine [51-43-4] (adrenaline) C2H23NO2, (1 R = CH3) was investigated (see Epinephrine and norepinephrine) (33). As in some other modem treatments, eg, xanthines and anticholinergics, the roots of P2" go Ast therapy for asthma can be found in historical records which document the use of herbal extracts containing ephedrine [299-42-3] C qH NO, (2) as bronchodilators. Epinephrine and ephedrine are stmcturaHy related to the catecholamine norepinephrine [51-41-2] CgH NO, (1, R = H), a neurotransmitter of the adrenergic nervous system (see Neuroregulators).

Patients often report a warm, flushed feeling as one of the side effects of injection of a contrast medium in preparation for a CAT scan. What causes this rise in body temperature The answer lies in the ionic nature of the contrast medium and in the body s attempt to regulate the concentrations of all substances in the blood.

When large volumes (i.e., more than a liter) of fluid are injected (such as in peritoneal dialysis, hyperalimentation, fluid replacement, and other conditions). Special consideration of fluid balance must be given to patients receiving large volumes, as well as careful consideration of the systemic effects of injection fluid components (e.g., amino acids and their nephrotoxicity). 

Tests are made by examining the inhibition caused by the substance on the sympathomimetic effects of injected adrenaline and of sympathetic nerve stimulation. Among the recently re-oommended anti-adrenaline drugs are iminazole derivatives (e.g. priscol (VIII))2 and / -haloalkylamines (e.g. dibenamine (IX)). The action of dibenamine is almost certainly that of destroying the receptor patches in the effector organ (p. 37).

Effect of Injection Volume. Table II shows the effect of injection volume on peak broadening and measured column efficiency. The bandwidths listed in Table II are due to injection volume alone, and were measured using an injector connected directly into the flowcell of a low-bandwidth detector. The plate reductions were then calculated for a 24,000 plate column, such as that represented by the bottom line of Table I, assuming 5 and 10 ml, respectively, for exclusion and total permeation volumes. Efficiencies of 23,000 plates at exclusion and 25,000 plates at permeation were actually measured for the column indicated in Table II. The effect of large injection volumes is thus to lose 25 to 50% of the potential column efficiency.

Effect of Injected Solvent. It was eventually determined that the mobile phase injected from the first SEC (i.e., pure THF) affected the separation in the second SEC. This is dreunatically demonstrated in Figure 13 which shows the result of injecting a narrow molecular weight distribution polystyrene sample directly into the second SBC. Mobile phase was of constant composition throughout (63.8% n-heptane in THF). However, the solvent used to dissolve the polystyrene was varied from 0% n-heptane in THF to 50% and plotted on the abscissa versus peak retention time on the ordinate. Peak retention time varied from 915 seconds at 0% n-heptane to 960 seconds at 50%. 

The consequences of this effect of injected solvent are as follows ( ) ...
