    Notes: Abstract An experiment to gain insight into the minimum toxic dose of fumonisins was conducted by feeding ponies rations with known fumonisin concentrations. Naturally contaminated corn screenings (CS) were blended with pellets, corn, and molasses to formulate individual daily diets. One group of 4 ponies was fed a ration with fumonisin B1 (FB1) varying from 〈1 ppm to 22 ppm. A second group of 5 ponies was fed a ration at varying rates containing 8 ppm FB1 for 180 days. A panel of clinical chemistry parameters was evaluated twice weekly for both groups. One pony in the first group died of equine leukoencephalomalacia (ELEM) after 225 days of which the final 55 days' diet contained 22 ppm FB1. Approximately 9 days prior to death, this animal experienced elevated liver chemistry values. All 5 ponies in the second group experienced mild, transient, clincal signs; were euthanized at 180 days; and had mild, histopathological brain lesions.

    Description / Table of Contents: Summary Liver blood flow (xenon-133 clearance method) and portal venous flow were mesured in cirrhotic and non cirrhotic rats following the infusion of vasopressin at varying rates. At low rates of infusion, vasopressin had no significant effect on portal venous flow or liver blood flow in cirrhotic or noncirrhotic rats. Infusion of vasopressin at a rate of 0.08 μU/g body wt/min in non-cirrhotic rats and 0.04 and 0.08 μU/g body wt/min in cirrhotic rats decreased portal venous flow and increased liver blood flow. At higher rates of infusion (0.2 μU/g body wt/min in non-cirrhotic rats and 0.16 μU/g body wt/min in cirrhotic rats) these effects were reversed. Furthermore, an infusion of 0.08 μU/g body wt/min vasopressin significantly reduced portal pressure in the cirrhotic rat. However, portal pressure was not significantly altered following an infusion of 0.16 μU/g body wt vasopressin. The implications of these findings in relation to the possible deleterious effects of high rates of vasopressin infusion in the management of portal hypertension and bleeding oesophageal varices is discussed.
    Notes: Zusammenfassung Die Leberdurchblutung (Xenon133 clearance Methode) sowie der portale Fluß werden nach Vasopressin-Infusion verschiedener Geschwindigkeiten, an cirrhotischen und nicht cirrhotischen Ratten gemessen. Bei langsamer Infusion hatte Vasopressin keine signifikante Wirkung auf den portal-venösen oder auf den Leberblutfluß in cirrhotischen oder nicht cirrhotischen Ratten. Die Infusion von Vasopressin mit einer Geschwindigkeit von 0,08 μU/g KG/min in nicht cirrhotischen Ratten und mit 0,04 bzw. 0,08 μU/g KG/min in cirrhotischen Ratten reduziert den portal venösen aber steigert den Leberblutfluß. Bei höherer Infusionsrate (0,2 μ,U/g KG/min in nicht cirrhotischen Ratten und 0,16 μU/g KG/min in cirrhotischen Ratten) wurde dieser Effekt umgekehrt. Darüber hinaus konnte eine VasopressinInfusion von 0,08 μU/g KG/min den portalen Druck bei cirrhotischen Ratten signifikant senken. Dagegen wurde der portale Druck durch Infusion von 0,16 μU/g KG/min Vasopressin nicht signifikant beeinflußt. Die Bedeutung dieser Befunde für eine mögliche deletäre Wirkung hoher Raten von Vasopressin-Infusion in der Behandlung der portalen Hypertension mit blutenden Oesophagus-Varicen wird diskutiert.
