Hydrogen sulfide (H(2)S) is a crucial co-modulator of cardiovascular, nervous, digestive and excretory systems function. The pleiotropic action of atorvastatin exceeds simple 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibition and involves multiple biological mechanisms. This study assesses the influence of atorvastatin on the H(2)S tissue concentration in mouse brain, liver, heart and kidney. Twenty-four female CBA strain mice received an intraperitoneal injection. The mice were given one of the following solutions: 0.1 mg atorvastatin (5 mg/kg of body weight (b.w.)/day - group D1, n = 8), 0.4 mg atorvastatin (20 mg/kg b.w./day - group D2, n = 8) or a saline physiological control (0.2 ml - group C, n = 8). A modified Siegel spectrophotometric method was used for the H2S tissue concentration measurements. There was a remarkable rise in the H2S concentration [mu g/g] in the kidney (C: 5.26 +/- 0.09, D1: 5.77 +/- 0.11, p = 0.0003; D2: 7.48 +/- 0.09, p < 0.0001). There were also slight H2S tissue level changes in the brain (C: 1.61 +/- 0.01, D1: 1.75 +/- 0.03, p = 0.0001; D2: 1.78 +/- 0.03, p < 0.0001), the heart (C: 4.54 +/- 0.08, D1: 4.86 +/- 0.10, p = 0.0027; D2: 4.56 +/- 0.07, p = 0.6997) and the liver (C: 3.45 +/- 0.03, D1: 3.27 +/- 0.02, p = 0.0001; D2: 3.31 +/- 0.02, p = 0.0003). Our study supports the influence of atorvastatin on H(2)S tissue concentration in kidneys and other mouse organs.
