Effect of uninephrectomy (1-K) and H2S supplementation on plasma homocysteine (Hcy) level. Total homocysteine was extracted from plasma and analyzed by high-performance liquid chromatography as described in materials and methods using our previously adopted procedure. Data represent the means ± SE, n = 4; NaHS, 30 μmol/l. *Significant difference (P < 0.05) compared with respective wild-type (WT) two kidney mice (2-K). **Significant difference (P < 0.05) compared with respective WT 1-K. CBS, cystathionine-β-synthase.
