Effects Of Insulin, Sodium And D-Glucose On Amino Acid Absorption In The Intestine Of Rats, Andre-Gerard Craan
Effects Of Insulin, Sodium And D-Glucose On Amino Acid Absorption In The Intestine Of Rats, Andre-Gerard Craan
Dissertations and Theses
Amino acid absorption across rat intestine in vitro was inhibited or stimulated by insulin depending on the hormone serosal concentration.
The absence of sodium ions from the incubating solution resulted in a significant decrease of L-alanine absorption. However, L-alanine was enhanced in a sodium-free medium by the addition of insulin on the serosal side of the intestine.
A sizable decrease in L-alanine and L-lysine absorption was produced by introduction of D-glucose (0.2 % and 2 %) in the Krebs-Ringer's incubating buffer. Nevertheless, the presence of D-glucose did not prevent the stimulatory effect of insulin on amino acid absorption.
Lactic Dehydrogenase Isozyme Isolation By Disc Electrophoresis In Eight Species Of Fringillid Birds, Michael Edwin Darling
Lactic Dehydrogenase Isozyme Isolation By Disc Electrophoresis In Eight Species Of Fringillid Birds, Michael Edwin Darling
Dissertations and Theses
Disc electrophoresis of tissue homogenates from eight species of fringillid birds showed five forms of lactic dehydrogenase. The relative amounts of isozymes were characteristic for each species. This paper classifies some members of the families Fringillidae and Carduelidae in terms of lactic dehydrogenase isozymes and compares the results to other methods of classification.
