Other claims from this paper (8)
- Intervention effect Exposure to 0.5 and 2.0 mM nitrite temporarily decreased GS level.
- Observation Nitrite content temporarily increased before GS level declined, peaking at six hours.
- Observation GS level was most depressed after 12 hours.
- Intervention effect The 0.3 and 0.4 mM nitrite effects were slight and nonsignificant after 18 hours.
- Intervention effect GS level did not fully recover after 24 hours without nitrite following 24 hours at 2 mM nitrite.
- Intervention effect Lack of sugar intensified nitrite inhibition of GS level.
- Intervention effect Nitrite did not affect GS transferase activity in vitro.
- Association The nitrite induced decrease in GS level accompanied KH3 excretion.
