Abstract
Animal cells are coated with complex carbohydrates. Insoluble analogues of these substances were prepared by coupling monosaccharides to Sephadex beads (crosslinked dextran), and the interactions between these derivatives and three established cell lines were studied. A virally transformed fibroblast, simian virus 40-transformed 3T3 cells, adhered to the beads derivatized with D-galactose, but did not adhere to the corresponding beads derivatized with D-glucose or N-acetyl-D-glucosamine. Cells that adhered to the galactose-beads appeared to initiate a nucleation process in that they became more adhesive towards the cells in suspension, leading to the formation of large aggregates containing both cells and galactose-beads. The results suggest that specific carbohydrates are involved in the processes of cell recognition or cell adhesion, or both.

Abstract
The positive inotropic action of glucagon on the cat heart is dependent upon the extracellular Ca concentration. The inotropic effect is proportionately greater, the lower the concentration of Ca in the perfusate (above zero, at which glucagon is without significant effect). Nevertheless, Ca influx (as measured with (45)Ca) into the myocardium is not demonstrably influenced by glucagon, except at 0.09 mM Ca, where the interpretation of the effect is complicated by the fact that there is mechanical asystole at that Ca concentration in the absence of glucagon, while excitation-contraction coupling still occurs when the hormone is added. The possibility is suggested that glucagon may influence intracellular movement of Ca, even when its transmembrane movement is affected only slightly.

Abstract
In the first 150 seconds after contracture of rabbit myocardium has been induced by shifting from perfusion with zero [Ca(2+)] and low [K(+)] to solutions with normal levels of those cations, there is a large influx of Ca(2+) as measured both by isotopic tracer flux and by total tissue [Ca]. Tracer studies indicate that the influx is 90 per cent complete in 90 seconds. Contracture due to substitution of either Li(+) or K(+) for Na(+) in perfusion fluids is also associated with an increased influx, but of lesser magnitude. The latter types of contracture are reversible while the former is not. It seems probable that the irreversible contracture is induced by the large Ca(2+) influx.
