It is important to establish effective methods for preventing colorectal cancer because the number of colorectal cancer deaths is increasing. Erythromycin one of the macrolide antibiotics, has been shown to exert pleiotropic effects, such as anti-inflammatory and anti-oxidative effects, on mammalian cells. In the present study, we aimed to evaluate the preventive effects of erythromycin on inte...

Seven hundred twenty-three isolates of Moraxella catarrhalis obtained from outpatients with a variety of infections in 30 medical centers in the United States between 1 November 1994 and 30 April 1995 were characterized in a central laboratory. The overall rate of beta-lactamase production was 95.3%. When the National Committee for Clinical Laboratory Standards MIC interpretive breakpoints for ...

Recent studies undertaken in southern Africa and elsewhere indicate that many short or single dose treatments are available to treat chancroid. Erythromycin 500 mg three times a day for five days, ciprofloxacin 500 mg, sulphamethopyrazine 800 mg and trimethoprim 1000 mg or sulphametrole 3200 mg and trimethoprim 640 mg as single oral doses, or ceftriaxone 250 mg as a single intramuscular injecti...

STUDY OBJECTIVES To investigate whether erythromycin therapy lowers the frequency of the common cold and subsequent exacerbation in patients with COPD. DESIGN Prospective, randomized, controlled, but not blinded, trial. PATIENTS One hundred nine patients with COPD were enrolled into the study. Patients were randomly assigned to erythromycin therapy or to no active treatment in September 199...

We characterized the effects of classical erythromycin resistance mutations in ribosomal proteins L4 and L22 of the large ribosomal subunit on the kinetics of erythromycin binding. Our data are consistent with a mechanism in which the macrolide erythromycin enters and exits the ribosome through the nascent peptide exit tunnel, and suggest that these mutations both impair passive transport throu...

A novel source of biological nitrogen produced by multi-strain fermentation was developed for erythromycin production. The nitrogen composition of corn steep liquor, biological nitrogen and soybean flour was optimized by using Response surface methodology (RSM) firstly. A Box-Behnken design was used to estimate the optimum nitrogen composition for the production of erythromycin as follows: corn...
