Laxative Abuse

Digestive Diseases, 1988
Two types of laxative abuse are described, namely habitual abuse and surreptitious abuse. Phenolphthalein and the anthraquinone derivatives have been most abused in this respect. Long-term anthraquinone use may lead to melanosis coli and cathartic colon, with typical histological and radiological features.

PGE-Mediated laxative effect of diphenolic laxatives

Naunyn-Schmiedeberg's Archives of Pharmacology, 1978
1. In the tied off colon of the anaesthetized rat in situ, the effect of diphenolic laxatives (bisacodyl and phenolphthalein) and of osmotic laxatives (mannitol, sodium sulfate and lactulose) on water net flux was studied. All the laxatives reduced water net flux from lumen to blood or reversed it into water net flux from blood to lumen ...

Pharmacology of Laxatives

Annual Review of Pharmacology and Toxicology, 1977
Effective laxative action results in an increase in fecal water excretion, and increased fecal water excretion is usually secondary to altered intestinal fluid and electrolyte movement. Both an understanding of the process(es) by which laxatives work and a classification of laxatives therefore should be based on the mechanism(s) by which cathartics ...

Lax pairs galore

Journal of Mathematical Physics, 1991
A formula that yields an (apparently—but only apparently—nontrivial) Lax pair for any nonlinear evolution PDE in 1+1 dimensions possessing a local conservation law is presented. Several examples are exhibited.
