Mucus in Intestinal Contents of Germfree Rats
The fecal excretion of total nitrogen and of total hexosamines has been determined in germfree and conventional rats. Germfree rats excreted more hexosamines than the conventional rats, while no difference in the nitrogen excretion was found. Infection of the germfree rats with a normal flora resulted in a temporarily increased excretion of hexosamines and nitrogen over a period of 2 to 3 days ...
متن کاملMucus in Intestinal Contents of Germfree Rats* by Goran
One of the differences between animals reared under germfree conditions and conventional 1 animals is the considerable enlargement of the germfree cecum. I t has been shown that the gross enlargement of the cecum is due to an increase in the amount of the cecal contents as well as to an increase in the weight of the cecal wall. When germfree animals were contaminated with a normal intestinal fl...
متن کاملResults of Experimental Intestinal Strangulation Obstruction in Germfree Rats
Experimental low ileal strangulation obstruction has been produced in germfree and conventional rats. The mean survival time was 240 hours in the germfree rats and 44 hours in the conventional controls. 4 of the 10 germfree rats survived 15 or more days, whereas the 10 conventional animals were all dead within 2(1/2) days. The strangulation obstruction fluid from the germfree animals was steril...
متن کاملUrinary Calculi in Germfree Rats
In a colony of germfree rats 50 per cent of the males had urinary calculi composed of calcium citrate and calcium oxalate. Genetically closely related conventional animals on the same sterilized diet did not present a single case of stone formation. The tendency to calculus formation disappeared when germfree animals were contaminated with the intestinal flora from conventional rats. The calcul...
متن کاملBilirubin and Urobilins in Germfree, Ex-germfree, and Conventional Rats
No urobilinogens are present in the feces or urine of germfree rats. After contamination of germfree animals with feces from conventional animals the exgermfree rats produced urobilins to the same extent as conventional animals on the same diet. The negative urobilin test turned positive in germfree animals infected with a single Clostridium-like microorganism isolated from the intestinal conte...
