Regulation of Nitric Oxide Production by δ-Opioid Receptors during Glaucomatous Injury
Figure 5
Measurements of nitrate-nitrite in normal and glaucomatous eyes in the presence of AG.
Animals were treated with AG (25 mg/kg, i.p.) 30 minutes after glaucomatous injury and continued for 7 days, once daily. The absorbance was measured at 550 nm and absorbance was plotted against the nitrate standards. The amount of nitrate-nitrite is expressed as millimolar nitrates-nitrites per milligram protein. Data are expressed as mean ± SEM, (*P<0.05; n = 4–6).
