Pharyngeal pumping

Octopamine is present in C. elegans (181), but its cellular distribution is not yet known. It acts antagonistically to 5-HT, to produce suppression of egg-laying and stimulation of pharyngeal pumping.

Lansoprazole is a proton pump inhibitor. Its safety profile has been reviewed based on premarketing chnical studies, and has to be regarded with the reservations appropriate to this type of material. In 4749 patients the most frequent adverse effects were headache (4.7%), diarrhea (3.2%), abdominal pain (2.2%), pharyngitis (1.8%), and nausea (1.4%) some patients had upper respiratory complaints or suffered anxiety or depression, or myalgia (1). The adverse reaction profile appears to be closely similar to that of omeprazole.
