(18) On the basis of previously obtained evidence that Gram-negative bacteria may influence the activity of leukaemia, a study of the composition of the flora, the immune stimulation by the Gram-negative bacteria and the endotoxin concentration in faeces was conducted in patients with low-grade malignant B-cell lymphoma as well as in patients with acute leukaemia.
(19) Rotaviruses and mycoplasma-like particles were observed in the faeces of calves with and without diarrhoea.
(20) The hepta-, hexa- and penta-carboxylic porphyrins found in the faeces of rats poisoned with hexachlorobenzene have been separated by high-pressure liquid chromatography and characterized largely by spectroscopie methods.
Stercobilin
Definition:
(n.) A coloring matter found in the faeces, a product of the alteration of the bile pigments in the intestinal canal, -- identical with hydrobilirubin.
Example Sentences:
(1) On the 2nd-3rd day all the animals developed one or several of the following symptoms or characteristics typical for germfree (GF) rats: no coprostanol formation, no stercobilin production, a GF pattern after gel electrophoresis of fecal supernatant and proteolytic activity in the feces.
(2) The residual part of urobilinogen is further reduced to urobilin, stercobilin and dipyrrolmethenes and excreted in the faeces.
(3) The relative bilirubin productions from erythrocyte haem degradation and early labeled bilirubin were determined by measuring the incorporation of [14C]glycine in erythrocyte haem and in fecal stercobilin.
(4) The bilirubin production rates from erythrocyte degradation (PE), ineffective erythropoiesis (PI) and catabolism of hepatic haemoproteins (PL), were derived from the incorporation of 14C-glycine into haemoglobin and stercobilin.
(5) Measurements of the temperature dependence of the circular dichroism spectra of l-stercobilin and d-urobilin show that the conformations of these optically-active urobilinoids change with temperature between 163 and 297 degrees K. These conformational changes depend critically on the hydrogen bonding characteristics of the solvent.
(6) Accordingly, natural (-)-stercobilin possesses the 2'(S), 7'(S) configuration, and has the configuration formula 6(1 (R), 2(R), 2'(S), 7'(S), 7(R), 8(R)).
(7) In five of the patients, the stercobilin-(14)C specific activity in a pooled specimen of feces was measured, enabling the following further values to be calculated: (a) the total (14)C radioactivity incorporated into bilirubin (21.0 and 25.3% [mean 23.2%] of the injected dose in two of the nonporphyric patients and between 8.5 and 25.3% [mean 14.2%] of the injected dose in the porphyric patients), and (b) the proportion of hepatic synthesized bilirubin delivered directly to plasma in the unconjugated form (between 0.520 and 0.904; mean for nonporphyric patients 0.712; mean for porphyric patients 0.614).
(8) i-Urobilin and 1-stercobilin were separated by high-performance liquid chromatography on a reversed-phase octadecylsilane-bonded column and detected fluorimetrically through formation of phosphor with zinc ions in the eluent.
(9) In both cases, unconjugated bilirubin accounted for a large percentage of the total bile biliary pigments measured, and stercobilin was present in gallbladder bile.
(10) The substituted oxo-tetrahydrodipyrromethane precursor, 5, for the total synthesis of (-)-stercobilins 3 and 4, in which the relative configuration between the asymmetric centers is known, yields 2(S)-methyl-3(S)-ethylsuccinimide (-2) under the same conditions of degradation.
(11) Chromic acid degradation of natural (-)-stercobilin (1) yields 2(R)-methyl-3(R)-ethylsuccinimide (+2), whereby the absolute configuration of 1 at the chiral centers C-1, C-2, C-7, and C-8 is established.
(12) The hepatic pool of porphobilinogen is labeled by means of an intravenous injection of delta-aminolevulinic acid-4-(14)C. The proportion of total bilirubin production which is derived from hepatic hemes is calculated from the ratio of the mean (14)C specific activities of stercobilin and porphobilinogen estimated in pooled specimens of feces and urine, respectively.
