The effect of fluoxetine hydrochloride, a 5-HT uptake inhibitor (60 mg/day PO), in preventing weight gain associated with nicotine reduction was investigated in participants in a double-blind, placebo-controlled smoking-cessation trial. A lunch of cheese pizza and chocolate bars was offered, and caloric intake was monitored. The analysis focused on subjects (placebo: n = 11; fluoxetine: n = 10)...

Biliary pseudolithiasis has been reported in patients who received ceftriaxone therapy. To examine this phenomenon further, serial gallbladder sonograms were evaluated in 44 adult patients who received intravenous ceftriaxone at 2 g or a placebo daily for 14 days in a double-blind controlled study. Ultrasound examinations of gallbladders were performed on days 1 and 14 of therapy and 2 weeks po...

BACKGROUND Norepinephrine transporter (NET) inhibition increases the responsiveness to vasoactive medications and attenuates the response to sympathetic stimuli. The phenomenon may be a result of impaired regulation of sympathetic vasomotor tone. METHODS AND RESULTS We studied the effects of the selective NET blocker reboxetine and placebo on baroreflex control of heart rate (HR) and sympathe...

OBJECTIVE To assess whether intermittent transdermal treatment with glyceryl trinitrate causes clinically significant rebound in patients maintained on beta blockers for stable angina pectoris. DESIGN Serial treadmill exercise testing in a double blind, randomised, placebo controlled cross over trial. Baseline exercise testing was performed at 0900 and 1100 at visit 1. Transdermal glyceryl tr...

1. Evidence has been found that Northrop's phenomenon (so called by us) is produced in the digestion of casein or hemoglobin brought about by trypsin, papain, and pepsin either crude or crystalline in the presence of gelatin. 2. Anson's and Kunitz' methods permit the measure of proteolytic activity of any protease on casein or hemoglobin substrate in the presence of gelatin, even in very small ...

Herpes zoster infection may cause postherpetic neuralgia, which is defined by prolonged pain predominantly mediated by central nervous system hypersensitivity. This phenomenon may be reversed by (S)-ketamine (SKET), but its use results in intolerable side effects, while its topical administration seems to be safe. It is a cross-over design study with 12 patients randomly divided into two groups...
