After 24 hours of cold storage, rat livers perfused ex vivo for 2 hours with blood supplemented with CO (300 parts per million) showed significantly decreased portal venous resistance and increased bile production, as compared with control livers perfused with blood devoid of CO.
Krebs-Henseleit buffer (KH) and cell culture media, i.e. media with largely similar "physiological" extracellular ion compositions (in particular with regard to sodium, potassium and chloride), in contrast, yielded a comparatively good cell survival when used for cold storage of rat hepatocytes, rat aortic valves and rat epidermal cells at 4°C [ 24, 27, 28].
The results showed increased glycogen storage in rats fed with the high-fructose diet without a difference in liver fat content between the control and high-fructose groups, indicating the predominance of gluconeogenesis over de novo fatty acid synthesis in the early phase response to a high-fructose diet.
Chemfil had significantly less leakage than intermediate restorative material after storage in rat (P <.05) for up to 20 days, but not after 30 days.
Frozen storage of rat striata may thus be valuable for experiments requiring lengthy assays, the accumulation of material, or the transport of samples from one laboratory to another for analysis.
The procedure described herein uses a simple method of freezing brain tissue (first cooling in ice-cold buffer and then freezing at −80 °C) that allows for the storage of rat striata followed by the assay of DA transport and K+-stimulated DA release using rotating disk electrode voltammetry.
Le Jossic-Corcos et al. [ 7] showed that fibrates decreased cholesterol efflux, cholesterol conversion into bile acids and cholesterol ester storage in rat hepatocytes.
The purpose of the present study was therefore to explore the effect of butyrate used as a nutrient on in vivo ATP metabolism and glycogen storage in rat liver.
Storage of rat red blood cells in this prospective randomized trial for 28 days impaired the ability to improve tissue oxygenation when transfused into either control or septic rats in a state of systemic oxygen uptake (VO2) supply dependency induced by isovolaemic haemodilution [ 35].
Contamination is mainly from two sources: food products from diseased poultry, hogs, and cattle; and wholesome food subsequently exposed to infected fecal matter during food storage (mice and rats) and during food preparation (human handlers).
