What's the difference between indican and indihumin?

Indican

Definition:

(n.) A glucoside obtained from woad (indigo plant) and other plants, as a yellow or light brown sirup. It has a nauseous bitter taste, a decomposes or drying. By the action of acids, ferments, etc., it breaks down into sugar and indigo. It is the source of natural indigo.
(n.) An indigo-forming substance, found in urine, and other animal fluids, and convertible into red and blue indigo (urrhodin and uroglaucin). Chemically, it is indoxyl sulphate of potash, C8H6NSO4K, and is derived from the indol formed in the alimentary canal. Called also uroxanthin.

Example Sentences:

(1) When applied as diagnostic tests for the stagnant loop syndrome, the phenol excretion showed 2 false negative results, the p-cresol excretion 3 false negative and 2 false positive results, and the indican excretion 6 false positive results.
(2) p-Cresol may therefore prove more sensitive than indican as an indicator of altered microbial metabolism due to saccharin.
(3) Intestinal protein metabolism and bile acid deconjugation (measured by urinary indican excretion and 14C-glycocholic acid breath test) was significantly enhanced in bypass patients.
(4) This diagnostic procedure was applied to the identification of patients with steatorrhoea due to the stagnant loop syndrome, and was compared with other tests for this condition, viz, study of the small intestinal bacterial flora, urinary indican excretion, and the Schilling test with added intrinsic factor.
(5) When Id and NaS were ingested together, the bladder mass increase was additive, but the epithelial hyperplasia was not exacerbated over that observed with each alone, and the urinary indican was equivalent to that produced by Id alone.
(6) Most indican excreted in the urine comes from the degradation of tryptophan through the action of microorganisms dwelling within the intestinal lumen.
(7) The colors are formed from the substrate indoxyl sulfate (indican) and all 7 patients had bacteria in the urine that would produce blue colonies on agar enriched with the urine (filter sterilized) of the patients involved.
(8) Determination of phenol and indican in a 24-hour urine sample is likely to provide a simple method for selecting patients with signs of abnormal bacterial colonization in the small intestine for more detailed investigations.
(9) A simple analytical procedure has been developed for the determination of indican and tryptophan in biological fluids by reversed-phase liquid chromatography using a new electrochemical detector consisting of a tubular anode obtained by moulding graphitized carbon black and polyethylene.
(10) The microbial catabolism of tryptophan to indole has been studied in 15 human subjects by analysis of the daily urinary excretion of indican (potassium indoxylsulphate) before, during and after chronic saccharin ingestion.
(11) Indican excretion was higher in patients with purple urinary catheter bags than in controls.
(12) By shortening the reaction time with the 2,4-DCPD reagent to 1.7 min, we find that the indican interference can be eliminated, without affecting quantification of total bilirubin in either normal or uremic sera.
(13) The excretion of indican (formed from indole, a microbial metabolite of tryptophan) was increased by saccharin in a dose-related fashion at all time points, but showed only a 3-fold increase at 7.5% compared with the 0% group.
(14) Increased excretion of indican has been noted, suggesting deficient intestinal absorption of L-tryptophan.
(15) The Jendrassik Bilirubin Reagent System (American Monitor) and a modified Jendrassik-Grof procedure (Hoffmann-LaRoche) adapted to the Cobas Bio analyzer were unaffected by the presence of indican.
(16) Treatment with pancreatic extract resulted in an immediate increase in indican excretion to above the normal range in patients with steatorrhoea due to pancreatic insufficiency.
(17) Saccharin-treated animals in both generations showed increased urinary excretion of indican.
(18) The urinary excretion of indican was increased in the fistula-operated rats, but further studies are needed to establish the significance of this observation.
(19) Indican also interfered with the Micro Bilirubin Reagent Set (Harleco) Malloy-Evelyn procedure, but to a much lesser extent.
(20) Concentrations of indican were about 1.5 those of tryptophan and considerably greater than those of indole-3-acetic acid in hemodialysate samples from 12 renal patients.
