Gastrointestinal urease in man ' Part I Activity of mucosal urease
The relationship postulated between hepatic coma and hyperammonaemia implicates the gastrointestinal tract as a major source of the excess ammonia in the peripheral blood of some patients with cirrhosis (Butt and Summerskill, 1961; Chalmers, 1960; Sherlock, Summerskill, White, and Phear, 1954). Conventional therapy, comprising protein restriction, antibiotics, and enemas, is directed toward eli...
متن کاملThe Activation of Urease
1. It has been shown that the activity of solutions of twice recrystallized urease is reversibly increased by moderate heating and reversibly decreased by storage in the cold, even in the frozen state. 2. Crude extracts of jack bean meal containing potent urease undergo this same type of reversible activation by heating and inactivation by cooling. Dilution has the same potentiating effect on t...
متن کاملUrease assay and urease-producing species of anaerobes in the bovine rumen and human feces.
A growth medium and test were developed for rapid detection of urease in fermentative anaerobic bacteria. Using nonselective rumen fluid roll-tube agar medium and the new test, it was confirmed that Peptostreptococcus productus is often the most numerous urease-forming species in human feces. Also, some fecal strains of Ruminococcus albus, Clostridium innocuum, and Clostridium beijerinckii prod...
متن کاملRecombinant urease and urease DNA of Coccidioides immitis elicit an immunoprotective response against coccidioidomycosis in mice.
Coccidioides immitis antigens which stimulate a T helper cell 1 (Th1) pathway of host immune response are considered to be essential components of a vaccine against coccidioidomycosis. Recombinant urease (rURE) and recombinant heat shock protein 60 (rHSP60) of C. immitis were expressed in Escherichia coli and tested as vaccine candidates in BALB/c mice. A synthetic oligodeoxynucleotide which co...
متن کاملStudies on Crystalline Urease
1. Crystalline urease is not inactivated by trypsin in the absence of a gum. In fact, the presence of trypsin alone in aqueous solutions of urease has an action similar to that of gum, that is, it acts as a "protective colloid" for urease. 2. Crystalline urease is inactivated by trypsin in the presence of a gum. This occurs with great rapidity if purified (crystalline) trypsin is used. 3. If tr...
