    editors, Todd A. Florin, Stephen Ludwig ; associate editors, Paul L. Aronson, Heidi C. Werner ; illustrations by Frank H. Netter ; contributing illustrators, Carlos A.G. Machado [and others].
    Summary: This book edited by Drs. Todd Florin and Stephen Ludwig, is a visual aid with more than 500 images by Dr. Frank Netter and other artists working in his style that will help you diagnose and care for children with common clinical conditions. This is the first time that Netter's drawings of pediatric illness are brought together in a single volume. The superb, accurate artwork accompanies up-to-date text contributed by physicians at the prestigious Children's Hospital of Philadelphia. The book provides you with all the at-a-glance information you need for a quick overview of common issues from nutrition, allergy, infectious disease, and adolescent medicine, to cancer and heart disease. Efficiently review key details for each condition with 500 detailed, crystal-clear images provided by Frank H. Netter and others working in the Netter tradition. Apply dependable, concise, clinical advice from a team of physicians at Children's Hospital of Philadelphia, one of the top children's hospitals in the U.S. Get answers at a glance during pediatric rotations when studying for exams or preparing for consultations.

    Na+, K+ and Cl- concentrations (cij) and activities (aij), and mucosal membrane potentials (Em) were measured in epithelial cells of isolated bullfrog (Rana catesbeiana) small intestine. Segments of intestine were stripped of their external muscle layers, and bathed (at 25 degrees C and pH 7.2) in oxygenated Ringer solutions containing 105 mM Na+ and Cl- and 5.4 mM K+. Na+ and K+ concentrations were determined by atomic absorption spectrometry and Cl- concentrations by conductometric titration following extraction of the dried tissue with 0.1 M HNO3. 14C-labelled inulin was used to determine extracellular volume. Em was measured with conventional open tip microelectrodes, aiCl with solid-state Cl-selective silver microelectrodes and aiNa and aiK with Na+ and K+-selective liquid ion-exchanger microelectrodes. The average Em recorded was -34mV. ciNa, ciK and ciCl were 51, 105 and 52 mM. The corresponding values for aiNa, aiK and aiCl were 18, 80 and 33 mM. These results suggest that a large fraction of the cytoplasmic Na+ is 'bound' or sequestered in an osmotically inactive form, that all, or virtually all the cytoplasmic K+ behaves as if in free solution, and that there is probably some binding of cytoplasmic Cl-. aiCl significantly exceeds the level corresponding to electrochemical equilibrium across the mucosal and baso-lateral cell membranes. Earlier studies showed that coupled mucosal entry of Na+ and Cl- is implicated in intracellular Cl- accumulation in this tissue. This study permitted estimation of the steady-state transapical Na+ and Cl- electrochemical potential differences (deltamuNa and deltamuCl). deltamuNa (-7000 J . mol-1; cell minus mucosal medium) was energetically more than sufficient to account for deltamuCl (1000--2000 J . mol-1).
