Abstract: Rat liver microsomal insulin-like growth factor-II (IGF-II) receptor has been purified to homogeneity using a single step affinity chromatographic procedure on agarose-IGF-II with elution at pH 4. Determined by either IGF-II binding or a direct RIA for receptor, purification of 2000-fold was obtained. The mean recovery was 28% for five such preparations. Sodium dodecyl sulfate-electrophoresis and autoradiography of purified receptor, radioiodinated receptor, and affinity-labeled receptor all indicated a molecular mass of approximately 250K. Scatchard analysis of IGF-II binding to purified receptor, solubilized microsomal membranes, or plasma membranes showed a single class of binding site with an affinity constant of 6 X 10(10) liter/mol in all cases. Potent antibodies to the purified receptor were raised in rabbits, capable of inhibiting 50% of IGF-II binding at dilutions of 1:170,000 and also of fully precipitating IGF-II-prelabeled receptor at 1:50,000. Both types of antibodies reacted with IGF-II receptors in rat adipose tissue, brain, heart, kidney, lung, and spleen. However, little cross-reactivity was seen with other species. Comparison of the ability of receptor antibodies to inhibit IGF-II binding to microsomal and plasma membranes indicated a specific immunological difference between the IGF-II receptors in the two membrane preparations.

Abstract: Small amounts (0.1-0.5 mM) of deoxycholate enhanced amylase secretion, which had been induced by submaximal doses of carbachol or cholecystokinin octapeptide, without affecting the maximal levels of these reactions from isolated rat pancreatic acini. Deoxycholate alone did not induce these reactions. The other bile acids such as cholate, chenodeoxycholate, ursodeoxycholate, and taurocholate were also active. Under the similar conditions, deoxycholate enhanced the secretagogue-induced diacylglycerol formation that was derived mainly from the phospholipase C-mediated hydrolysis of phosphatidylinositol and phosphatidylinositol-4-monophosphate. Deoxycholate did not enhance the secretagogue-induced hydrolysis of phosphatidylinositol-4,5-bisphosphate or Ca2+ mobilization. Deoxycholate did not affect amylase secretion, which was induced by the simultaneous addition of protein kinase C-activating 12-O-tetradecanoylphorbol-13-acetate and Ca2+ ionophore ionomycin. Since diacylglycerol and Ca2+ may be responsible for the secretagogue-induced amylase secretion, our results indicate that small amounts of bile acids increase the sensitivity to the secretagogue of diacylglycerol formation and subsequent activation of protein kinase C, and thereby enhance amylase secretion from pancreatic acini.

Abstract: The key determinants of alveolar capillary perfusion are transit times and the extent of recruitment. Capillaries are known to be heavily recruited in the dependent lung, but there are no direct data that bear on how capillary transit times might be affected by gravity. We directly determined mean capillary transit times on the surface of the upper, middle, and lower lung by measuring the passage of fluorescent dye through the capillaries using in vivo television microscopy. In anesthetized dogs, mean capillary transit times averaged 12.3 s in the upper lung, 3.1 s in the midlung, and 1.6 s in the lower lung. This near order of magnitude variation in speed of blood transit establishes that there is a vertical gradient of capillary transit times in the lung. As expected, dependent capillary networks were nearly fully recruited, whereas relatively few capillaries were perfused in the upper lung. The lengthy transit times and sparsely perfused capillary beds in the upper lung combine to provide a substantial part of pulmonary gas exchange reserve.
