| is gip a glucagon cell constituent? | "gastric inhibitory peptide" or "glucose-dependent insulin-releasing peptide" (gip) is a member of the gut hormone family. its physiological action is thought to be related to its insulinotrophic effect. the occurrence and distribution of gip was studied by immunohistochemistry. in all species examined including man, gip immunoreactivity was found to reside in the glucagon cells of the pancrease and gut. three pancreatic glucagonomas were found to contain numerous cells displaying gip and glucag ... | 1978 | 104936 |

| the distribution of disulfide-groups in descemet's membrane, lens capsule, and zonular fibers. | zonular fibers contain large quantities of disulfide-groups which histochemically can be demonstrated after thiosulfation or reduction with sodium thioglycollate. zonular fibers share these staining behaviours with oxytalan fibers and elastic fiber microfibrils. smaller amounts of disulfide-groups can be demonstrated when visualized by means of the thioglycollate/ferric-ferricyanide method. diffusion of acidic staining solutions seems to be limited in descemet's membrane and in the lens capsule: ... | 1978 | 105554 |
| capillary permeability measured by bolus injection, residue and venous detection. | kinetic analysis of residue and outflow curves of gamma-emitting indicators such as chromium-51-edta and iodide-131-thalamate from skeletal muscle gives the possibility to determine the extraction fraction and the plasma flow, and from these two values the capillary diffusion capacity can be calculated (sejrsen 1970, preliminary report). this is possible both for the transport from blood to tissue and from tissue to blood. this alternative method has been compared in the autoperfused cat gastroc ... | 1979 | 105564 |

| hypothalamic neurones in culture. i. a short review of the literature. | this article probably represents the first comprehensive attempt to review the fast growing literature dealing with mammalian hypothalamic neurones in long-term cultures. the bulk of the experimental data on this topic printed before the second half of 1978 deals with endocrine neurones, their development, their bioelectric properties, their biosynthetic capabilities and with mechanisms of hormone secretion. most initial studies had been concerned with providing evidence that hypothalamic endocr ... | 1979 | 112246 |

| methadone-induced changes in the visual evoked response recorded from multiple sites in the cat brain. | visual evoked responses (vers) and eeg were recorded following the i.p. administration of five doses of methadone (0.5--4 mg/kg) to 12 adult cats, which were implanted with cortical and subcortical electrodes. additional cats, subjected to the same drug regimen, were used to evaluate plasma methadone concentrations. doses of methadone that produced plasma concentrations between 80 and 190 ng/ml differentially affected vers recorded from cortical and subcortical sites. of the subcortical structur ... | 1979 | 112628 |

| retinal oxygenation via the choroidal circulation. | the possibility of supplying normal amounts of oxygen to the inner layers of the retina by diffusion from the choroid in the presence of retinal arterial obstruction was studied in cats and rhesus monkeys. while the animals were under general anesthesia, an oxygen electrode was placed in the vitreous cavity immediately adjacent to the retina, and a retinal artery blocker probe was used to occlude various segments of the retina blood supply. the inspired oxygen concentration was alternated betwee ... | 1978 | 112752 |
