Accordingly, for protonated substances, the extent of reabsorption is dependent upon urinary pH or the degree of dissociation. The degree of dissociation varies as a function of the urinary pH and the pKa, which represents the pH value at which half of the substance exists in protonated (or unprotonated) form.
Oral administration of 10–30 mL of castor oil is followed within 0. 5 to 3 h by discharge of a watery stool. Ricinoleic acid, but not the oil itself, is active. It arises as a result of the regular processes involved in fat digestion: the duodenal mucosa releases the enterohormone cholecystokinin/pancreozymin into the blood.

 

When bacteria are in their growth and replication phase, penicillins are bactericidal; due to cell wall defects, the bacteria swell and burst. Penicillins are generally well tolerated; with penicillin G, the daily dose can range from approx. 0. 6 g i. m. (= 106 international units, 1 Mega I. U. ) to 60 g by infusion.
This can be achieved by chemical or physical means; the latter will not be discussed here. Sterilization refers to the killing of all germs, whether pathogenic, dormant, or nonpathogenic. Antisepsis refers to the reduction by chemical agents of germ numbers on skin and mucosal surfaces.
