Mucous cells and enteroendocrine cells of the pyloric region of the ruin lizard (Podarcis sicula campestris De Betta) have been examined by lectin histochemical and immunohistochemical methods. Binding to five plant lectins (Canavalia ensiformis, Con A; Triticum vulgare, wheat germ, WGL; Lotus tetragonolobus, winged pea, WPL; Glycine max, soybean, SBL; Arachis hypogaea, peanut, PNL) was performed to characterize glycoconjugates in the secretory products of superficial and glandular mucous cells. Lectin histochemistry revealed the presence of N-acetyl-D-galactosamine, D-galactose and N-acetyl-D-glucosamine in the pyloric superficial cells. Mucous glandular cells mainly contained neutral glycoproteins with terminal residues of galactose, N-acetyl-D-glucosamine and N-acetyl-D-galactosamine. These cells did not react with Con A after periodate oxidation-sodium borohydride reduction (Paradoxical Con A staining). In the pyloric glands three different types of endocrine cells were identified immunohistochemically: gastrin-, serotonin- and somatostatin-immunoreactive cells; VIP-, bombesin- or cholecystokinin-immunoreactive cells have not been found in the pyloric mucosa.

We used tracer and arteriovenous difference techniques in conscious dogs to determine the effect of nonesterified fatty acids (NEFAs) on net hepatic glucose uptake (NHGU). The protocol included equilibration ([3-(3)H]glucose), basal, and two experimental periods (-120 to -30, -30 to 0, 0-120 [period 1], and 120-240 min [period 2], respectively). During periods 1 and 2, somatostatin, basal intraportal insulin and glucagon, portal glucose (21.3 micromol.kg(-1).min(-1)), peripheral glucose (to double the hepatic glucose load), and peripheral nicotinic acid (1.5 mg.kg(-1).min(-1)) were infused. During period 2, saline (nicotinic acid [NA], n = 7), lipid emulsion (NA plus lipid emulsion [NAL], n = 8), or glycerol (NA plus glycerol [NAG], n = 3) was infused peripherally. During period 2, the NA and NAL groups differed (P < 0.05) in rates of NHGU (10.5 +/- 2.08 and 4.7 +/- 1.9 micromol.g(-1).min(-1)), respectively, endogenous glucose R(a) (2.3 +/- 1.4 and 10.6 +/- 1.0 micromol.kg(-1).min(-1)), net hepatic NEFA uptakes (0.1 +/- 0.1 and 1.8 +/- 0.2 micromol.kg(-1).min(-1)), net hepatic beta-hydroxybutyrate output (0.1 +/- 0.0 and 0.4 +/- 0.1 micromol.kg(-1).min(-1)), and net hepatic lactate output (6.5 +/- 1.7 vs. -2.3 +/- 1.2 micromol.kg(-1).min(-1)). Hepatic glucose uptake and release were 2.6 micro mol. kg(-1). min(-1) less and 3.5 micro mol. kg(-1). min(-1) greater, respectively, in the NAL than NA group (NS). The NAG group did not differ significantly from the NA group in any of the parameters listed above. In the presence of hyperglycemia and relative insulin deficiency, elevated NEFAs reduce NHGU by stimulating hepatic glucose release and suppressing hepatic glucose uptake.
