We have previously demonstrated that nitroso-chloramphenicol (NO-CAP) in small concentrations causes the hydrolysis of isolated double stranded DNA in vitro and this action is blocked by sulfhydryl groups. The present study was designed to assess damage to isolated DNA as well as intact cells DNA and examine the protective effect of N-acetylcysteine (NAC). Using alkaline sucrose gradient sedimentation and the alkali elution technique of Kohn we were able to demonstrate DNA damage in Raji cells as well as phytohemagglutinin stimulated human lymphocytes after exposure to NO-CAP. Damage could be totally blocked by NAC. In preliminary studies we also observed that NAC protects bone marrow cells from the growth-inhibitory effects of chloramphenicol and thiamphenicol.
This research output has an Altmetric Attention Score of 3. 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 04 March 1997.
All research outputs
#7,557,593
of 23,053,169 outputs
Outputs from Respiration
#347
of 1,280 outputs
Outputs of similar age
#49,909
of 171,369 outputs
Outputs of similar age from Respiration
#43
of 201 outputs
Altmetric has tracked 23,053,169 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,280 research outputs from this source. They receive a mean Attention Score of 4.8. This one is in the 41st percentile – i.e., 41% of its peers scored the same or lower than it.
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 171,369 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 201 others from the same source and published within six weeks on either side of this one. This one is in the 6th percentile – i.e., 6% of its contemporaries scored the same or lower than it.
