    Description / Table of Contents: Résumé On trouve de l'insuline immunoréactive dans la bile hépatique de lapins normaux. Moins de 1% d'une dose injectée d'insuline bovine atteint la bile. Quand de l'insuline bovine 125I, seule ou liée à l'anticorps, est administrée par voie intraveineuse, seulement 40% de la radioactivité retrouvée dans la bile est précipitable avec l'acide trichloracétique et moins de 10% réagit avec le sérum anti-insuline de cobaye. Le glucose, le fructose le galactose, le tolbutamide et la phenformine provoquent tous une élévation de l'insuline dans la bile, qui atteint son maximum 40 à 50 min après l'injection. L'alloxane atténue ou abolie ces réponses.
    Abstract: Zusammenfassung Immunoreaktives Insulin wird in der Leber-Galle normaler Kaninchen gefunden. Weniger als 1% einer injizierten Dosis von Rinder-Insulin erreicht die Galle. Wenn man reines oder an Antikörper gebundenes 125I-Rinderinsulin intravenös verabreicht, lassen sich mit Hilfe von Trichloressigsäure nur 40% der Radioaktivität ausfällen, die in der Galle gefunden wird, und weniger als 10% reagieren mit Meerschweinchen-Anti-Insulinserum. Glucose, Fructose, Galaktose, Tolbutamide und Phenformin verursachen ein Ansteigen von Insulin in der Galle, welches ein Maximum innerhalb von 40 bis 50 Min. nach der Injektion erreicht. Alloxan vermindert oder hebt diese Effekte auf.
    Notes: Summary Immuno-reactive insulin is found in the hepatic bile of normal rabbits. Less than 1% of an injected dose of bovine insulin reached the bile. When 125I-bovine insulin alone or complexed with antibody was given intravenously, only 40% of the radioactivity recovered in the bile was precipitable with trichloracetic acid, and less than 10% reacted with guinea pig anti-insulin serum. Glucose, fructose, galactose, tolbutamide and phenformin all caused an elevation in bile insulin, which reached a maximum 40 to 50 min after the injection. Alloxan attenuated or abolished these responses.

    Notes: Abstract In clinical islet transplantation to patients with type 1 diabetes mellitus, the number of isolated and purified islet has been identified as a key determinant for functional success of the islet graft [1]. With improved isolation methods based on the original procedure published by Ricordi et al. [2] yield and function of isolated islets were considerably enhanced. However, there is still a large variance in the number, purity, viability and secretory capacity of islets isolated from brain-dead human donor pancreata, significantly hampering utilization of human islet preparations derived from a single donor for one diabetic recipient. The reasons for the limited success in islet isolation and purification have not been clarified in detail yet. Recent studies have indicated, that donor preconditions, and a number of technical factors during organ procurement and the islet isolation process itself are critical to successful islet isolation [3, 4]. This study aimed at identifying distinct morphological and histopathological characteristics of the donor pancreas as determinants for the outcome of human islet isolation and purification.

    Notes: Summary We have investigated whole body protein turnover in the fasted state in five normal men, five male Type 1 diabetic patients off insulin therapy, and five obese women, using IV 13C-leucine as a tracer. In diabetic patients, there was, as expected, a greater net loss of protein in the fasted state than in normal subjects. However, contrary to animal and studies in vitro, our diabetic patients in the fasted state showed a greater rate of protein synthesis than normal subjects (P〈 0.01). The increased net loss of protein in diabetic patients compared with normal subjects arose because, in the diabetic patients, protein breakdown was increased even more than protein synthesis under the conditions of this study. Plasma leucine concentration was higher in diabetic and in insulin-insensitive obese patients than in normal subjects (p〈 0.01), and higher in diabetic than in obese patients (p〈0.05). The rate of protein synthesis per kg lean body mass was also higher in diabetic patients than in obese or normal subjects (P〈0.01), and higher in obese than in normal subjects (p〈0.05). We conclude that, in human subjects, whole body leucine and protein metabolism are very sensitive to the action of insulin.
