Cyclosporine A induced renal damage was evident from the decreased activities of tissue marker enzymes (alkaline phosphatase, acid phosphatase, lactate dehydrogenase, aspartate transaminase and alanine transaminase) and decreased activities of ATPases (Na+, K+-ATPase, Ca2+-ATPase and Mg2+ ATPase).
The decreased activities of SOD, GSH and CAT, and increased MDA level were inhibited by SPG treatment.
First, the decline in systemic NAD+ biosynthesis could be an important trigger for a variety of pathophysiological changes that significantly contribute to aging through decreased activities of SIRT1 and other sirtuins.
Striatum had the greatest percentage of decreased activities of total SOD and Mn SOD, whereas cortex had the greatest percentage decrease in the activity of Cu/Zn SOD in arsenic-alone treated rats.
Inoculation with B. cepacia VM1468 resulted in decreased Ni and TCE phytotoxicity, as measured by 30% increased root biomass and up to 50% decreased activities of enzymes involved in anti-oxidative defence in the roots.
Induction of diabetes was associated with a marked reduction in glutathione (GSH) levels; decreased activities of GSH peroxidase (GSH Px), manganese superoxide dismutase (MnSOD) and catalase; increased reactive oxygen species (ROS) levels and iNOS activity in plasma and lymphoid organs.
Benzoxanthone 8, bearing angularly fused aromatic rings, and reduced benzoxanthone 5 showed decreased activities, strongly suggesting that linearly conjugated π-systems play a crucial role in the inhibition process.
However, post treatment with Ceftriaxone (100 and 200 mg/kg) significantly improved the motor deficits and attenuated the oxidative damage indicating decreased rise of LPO and nitrite concentration and restored the decreased activities of endogenous antioxidant enzyme (Glutathione, Catalase, SOD).
Mitochondrial dysfunction, a central deleterious event in renal stone crystallization, was evident by decreased activities of electron transport chain complex I, II and IV, augmented mitochondrial ROS, reduced GSH/GSSG ratio, which resulted in the mitochondrial permeability transition pore (mPTP) opening as indicated by increased mitochondrial swelling in hyperoxaluric rats.
All complexes and citrate synthase (CS) showed decreased activities in the KO mice, although activity per amount of CS, a measure for mitochondrial density, was normal.
The observed increased activities of SOD and catalase in the alcohol – only treated group contradicts Das and Mukherjee [2] who reported decreased activities in alcoholic lung injury.
