Inactivation by Nitrous Oxide
Myelo-cytotoxicity of extended nitrous oxide (N,O) inhalation was described almost forty years ago and then incidentally applied already with temporary success for suppressing leukemia. In 1948 the accompanying megaloblastic maturation arrest was explained by inactivation of the methylcobalamin coenzyme and subsequent folate deficiency. We studied the anti-leukemic effect of N, O on a transplan...
متن کاملNitrous oxide reduction by members of the family Rhodospirillaceae and the nitrous oxide reductase of Rhodopseudomonas capsulata.
After growth in the absence of nitrogenous oxides under anaerobic phototrophic conditions, several strains of Rhodopseudomonas capsulata were shown to possess a nitrous oxide reductase activity. The enzyme responsible for this activity had a periplasmic location and resembled a nitrous oxide reductase purified from Pseudomonas perfectomarinus. Electron flow to nitrous oxide reductase was couple...
متن کاملReduction of dinitrogen.
C onversion of dinitrogen to ammonia is required for all life. This conversion is accomplished by metalloenzymes on a scale of 108 tons year, a scale equivalent to that of the Haber–Bosch process (1) for making ammonia from dinitrogen and dihydrogen at high temperatures (350–550°C) and pressures [150–350 atmosphere (atm); 1 atm 101.3 kPa]. Although the benefit of crop rotation has been known fo...
متن کاملTemporal change in nitrous oxide and dinitrogen from denitrification following onset of anaerobiosis.
Similar temporal patterns were found in three mineral soils for the composition of the gaseous products of denitrification following the onset of anaerobic conditions. During the early period of anaerobiosis (0 up to 1 to 3 h), N(2) was the dominant product of denitrification. The NO(3) --> N(2)O activity then increased, but was not accompanied by a corresponding increase in N(2)O-reducing acti...
متن کاملNitrous oxide produces a non-linear reduction in thiopentone requirements.
We studied 88 healthy, ASA I patients (aged 20-45 yr), to determine if nitrous oxide affects thiopentone requirements for achieving 50% probability of no movement in response to verbal commands (CP,50). Patients were allocated randomly to one of four nitrous oxide concentration groups (0%, 20%, 40% and 60%). Patients in each group were also allocated randomly to receive predetermined target pla...
