“ Vitamin C , which decreased plasma isoprostanes and increased plasma antioxidant capacity, increased the response to ACh and restored the inhibiting effect of L-NMMA.”

“Membrane depolarization caused by incubation in high potassium (K+ = 28 or 56 mM) medium stimulated release of FSH, LH, and AA that was blocked by NMMA.”
“ NMMA also inhibited LHRH-induced LH and FSH release and gonadotropin release in the presence of both LHRH and AA , whereas sodium nitroprusside, a releaser of NO, stimulated LH and FSH release.”
“The FSH and LH release in response to AA was blocked by incubation with NG-monomethyl-l-arginine (NMMA) (300 μM), a competitive inhibitor of NO synthase.”

“An inhibitor of NO synthase (NOS), N(G)-monomethyl-l-arginine (NMMA), prevented the increase in medium concentrations of AA and LH-RH induced by high [K(+)], suggesting that NO mediates release of both AA and LH-RH.”

“ Vit C increased the response to ACh (509 ± 57%; P < 0.01 vs ACh alone) and restored the inhibiting effect of L-NMMA (332 ± 42, -34 ± 8%; P < 0.001).”
