Implication

Hypothesis-generating for NAC in experimental glomerulonephritis; human trials needed before any clinical consideration.

Structured PICO

P
Population
Rat model of Thy 1 glomerulonephritis induced by intravenous anti-Thy 1 antibody
I
Intervention
N-acetyl-cysteine (NAC) (i.p. 1,000 mg/kg, 1 h prior to anti-Thy 1) and soluble complement receptor 1 (sCR1)
C
Comparator
Untreated nephritic rats/glomeruli
O
Outcome
Glomerular nitrite (NO-2) synthesis, iNOS mRNA expression, and reactive oxygen species (ROS) chemiluminescencesurrogate

In a rat model of Thy 1 glomerulonephritis, inhibition of ROS by NAC or complement by sCR1 suppresses iNOS induction and subsequent injury, indicating complement-dependent ROS generation is the initiating event.
