The differing effects of acute and chronic alcohol on gastric and intestinal permeability.

Objective: Acute and chronic alcohol intake cause GI symptoms because of either alcohol-induced structural or functional abnormalities. In theory, the disruption of the integrity of the gut mucosa should be reflected by changes in the absorption of molecular probes, such as lactulose, mannitol, and sucrose. Accordingly, we investigated the effects of acute and chronic ethanol on the permeability of the gastric and small intestinal mucosa.

Attention deficits disorder and drug abuse.

Recent research studies have attempted to explore various aspects of attention deficit disorder and substance abuser subtypes. The purpose of the present study is to evaluate the effect of drug abuse on MMPI scale score profiles of alcoholics with or without attention deficit disorder symptoms. For the alcoholic group with ADDRT versus the alcoholic group with ADDRT and drug abuse there were no significant differences between the groups.

The perineal field in the external irradiation of cancer of the prostate: a modified Regato technique. First Annual del Regato Distinguished Lecture.

(1) 50 consecutive patients with cancer of the prostate, stages A2 through C2 received external irradiation. The whole pelvis was treated using 4-MV photons, and a prostate boost was given through the perineum using a cesium-137 teletherapy unit. (2) The treatment technique was easily duplicated daily and was well tolerated.
