Chronic ethanol intake induces ductal alterations in the parotid gland similar to those seen in the pancreas. These results suggest a common histopathological effect of alcohol in the ductal system of the parotid gland and pancreas and raise the possibility that the parotid sialogram could be useful as an adjunct in the diagnosis of ethanol-induced chronic pancreatitis.
OBJECTIVE: To investigate the effect of erythromycin on orocecal transit time (OCTT) in 17 healthy male subjects in a double-blind, placebo controlled crossover trial.SUBJECTS AND METHODS: After an overnight fast, each subject received 250 mg erythromycin base, 500 mg erythromycin base or placebo on three different days. A standardized breakfast meal plus 20 g lactulose was administered 30 mins after ingestion of the test dose. Exhaled breath was collected and hydrogen concentration was assessed over 4 h. Hydrogen concentrations over time for each session were analyzed by a generalized logistic function generating a sigmoidal curve. The ‘front’ transit time (T1) was taken as the time when a sustained rise in breath hydrogen concentration was first observed. The midpoint from baseline to peak hydrogen concentration was denoted T2and represented the time when approximately half of the test meal had reached the cecum.RESULTS: There was no effect of erythromycin on OCTT. The T1(mean ± SEM) was 103.2±11.2, 103.3± 15.3 and 70.9±15.9 mins for placebo, 250 mg erythromycin base and 500 mg erythromycin base, respectively (P>0.05). Similarly, the T2was 113.3±11.3, 113.9± 16.5 and 99.3±15.3 mins for the three regimens.CONCLUSIONS: Oral administration of erythromycin does not alter OCTT in healthy male subjects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
