Preoperative skin preparation with antimicrobial agents decreases the risk of surgical site infection, but concerns have been raised about the visibility of a common surgical preparatory agent (ChloraPrep; Becton, Dickinson & Co, Franklin Lakes, New Jersey), depending on skin pigmentation. Poor visibility may lead to failure to identify inadequately prepared skin, increasing the risk of surgica...

The antiserum against mouse growth hormone (MGH) was produced by immunizing monkeys and some basic immunological properties of the antiserum were studied. The antiserum formed single precipitin lines in agar gel double diffusion plate against both MGH preparation and the crude extract of mouse anterior pituitaries, but reacted with neither normal mouse serum nor the crude extracts of several vi...

Spread of excitation in isolated canine bundle branches was examined by microelectrode technique in order to investigate the possibility of dissociated impulse transmission in normal Purkinje fibers. In all experiments, local excitation of the preparation evoked either by fine bipolar extracellular electrodes or an intracellular microelectrode proceeded much faster along the longitudinal axis o...
