| Abstract |
Impaired butyrate oxidation and raised counts of sulfate-reducing bacteria in the colon of patients with ulcerative colitis (UC) indicate that the disease may be induced or aggravated by hydrogen sulfide toxicity. We aimed to examine enzymatic removal of H(2)S in erythrocytes and colonic mucosa from controls and patients with UC and Crohn's disease (CD). Rhodanese (RHOD) and thiol methyltransferase (TMT) activities were measured in rectal mucosa and erythrocytes, and plasma thiocyanate was determined. Four groups were analyzed: patients with UC, patients with CD, hospital controls (patients with dyspepsia or IBS), and a group of healthy volunteers. RHOD and TMT activity in rectal biopsies did not differ significantly between controls and patients with UC or CD (n=56). Control levels of RHOD were significantly higher in men than in women (212+/-25 and 132+/-14 nmol/mg/min, respectively; P<0.01). In erythrocytes (n=128) RHOD activity was significantly higher in UC patients than in hospital or volunteer controls (1.15+/-0.12 compared with 0.88+/-0.12 and 0.66+/-0.02 nmol/mg/min; P<0.05 and P<0.02, respectively). TMT activity was also significantly higher in erythrocytes from UC patients and hospital controls than volunteer controls (2.02+/-0.13 pmol/mg/min [P<0.001], 1.51+/-0.21 pmol/mg/min [P<0.05], and 1.17+/-0.18 pmol/mg/min, respectively). We found no evidence of defective enzymic detoxication of sulfide by RHOD or TMT in patients with UC or CD. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 September 2019.
All research outputs
#7,972,696
of 24,677,985 outputs
Outputs from Digestive Diseases and Sciences
#1,409
of 4,540 outputs
Outputs of similar age
#45,089
of 170,062 outputs
Outputs of similar age from Digestive Diseases and Sciences
#17
of 37 outputs
Altmetric has tracked 24,677,985 research outputs across all sources so far. This one has received more attention than most of these and is in the 67th percentile.
So far Altmetric has tracked 4,540 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.9. This one has gotten more attention than average, scoring higher than 68% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 170,062 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 37 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
