Reference strains of enterotoxigenic Escherichia coil (EtEC), non-EtEC, and other enteropathogenic bacteria were used to prove the reliability of Lt-DNA gene hybridization. In the test, Lt-DNA gene hybridization was compared with plate immunohemolytic test (PIHt) in identifying Lt-EtEC. the results obtained by both methods showed no significant differences. 791 strains of E. coil isolated from 1 875 children with acute diarrhea in taiyuan Children’s Hospital were examined for Lt-EtEC by Lt-DNA gene hybridization and PIHt. 289 strains examined by Lt-DNA gene hybridization were Lt positive, while 205 strains examined by PIHt were Lt positive. three different assays were done: colony hybridization, PIHt and fecal direct blot hybridization on each of 74 fecal specimens from children with acute diarrhea. It was found that identification of Lt-EtEC using fecal direct blot hybridization is a simple, sensitive and more practical method.

Eighteen patients with acute hemorrhagic necrotizing pancreatitis who survived from operation were followed up for 12 to 43 months. Late complications including pancreatic external fistula, pseudocyst, hyperglycemia, etc were reviewed. the pancreatic juice was collected through endoscopic cannulation. the volume and HCO3- concentration of the pancreatic juice and three kinds of pancreatic enzymes were measured. the results demonstrated that inspite of anatomic abnormality or functional impairment of the pancreas, the pancreatic insufficiency rarely manifested to be marked because of the compensative ability of the viable exocrine pancreas.
