CONSTITUENTS OF LYMPH FROM THE NON-SECRETING STOMACH OF THE DOG

MJ Keyl, ACK Chang, RT Dowell

Abstract


Gastric lymph collected from the non -secreting stomach of anesthetized dogs contained glucose, Na+, K+ and creatine phosphokinase in concentra ­ tions that were similar to those in arterial and gastric venous plasma. Gastric lymph contained greater concentrations of pyruvate and lactate than in either arterial or gastric venous blood. Gastric lymph contained a high concentration of total protein similar to that in simultaneously collected hepatic lymph. Gastric lymph was collected before and  after  the  pylorus was ligated and the stomach distended with air. These  procedures were used  in  another  study  in  which  total  protein  in  gastric  lymph  was reported to be much  lower  than  found  in  the  present  study. The lymph to plasma ratio for protein  was  decreased from 0.85 ± .04 to 0.69 ± .04. Pyloric ligation alone caused no change  in  lymph  protein concentration.
