AI Article Synopsis
- - The study investigated the antioxidant effects of vitamin C on liver and kidney tissues in mice, comparing groups treated with or without ciprofloxacin (CFX), a common antibiotic.
- - Results showed that vitamin C significantly reduced lipid hydroperoxides (indicators of oxidative stress) in both the liver and kidney of mice, particularly when combined with CFX treatment.
- - Furthermore, the study highlighted that measuring lipid hydroperoxides (LOOH) is a more sensitive method for assessing oxidative damage compared to thiobarbituric acid reactive substances (TBARs), suggesting that vitamin C may help counteract oxidative stress caused by CFX.
Article Abstract
In the present study, the antioxidant capacity of vitamin C was examined in the liver and the kidney tissues of mice with or without ciprofloxacin (CFX) treatment. The antioxidant capacity of the vitamin was evaluated in terms of lipid hydroperoxides (LOOH) and thiobarbituric acid reactive substances (TBARs). The experimental design was 15 days of water (control and CFX groups) or vitamin C (vitamin C and vitamin C plus CFX groups) in drinking water. One dose of CFX was injected, 15 minutes before sacrifice, in the corresponding mice. The initial nmol of lipid hydroperoxides/g of tissue were 137 +/- 11 in the kidney and 145 +/- 15 in the liver, and the nmol of TBARs were 13 +/- 0.7 and 12 +/- 0.6, respectively. Pre-treatment with vitamin C reduced the levels of LOOH in the liver to 45 +/- 11 (p < 0.01) and vitamin C with CFX injection to 54 +/- 9 (p < 0.01). Vitamin C treatment also reduced the LOOH levels in the kidney roughly duplicated by CFX. Through the TBARs method we have not observed these effects. Quantification of LOOH is more sensitive than that of TBARs for estimating lipid peroxidation. CFX is used especially for urinary infections and can produce oxidative stress in the kidney. Pre-treatment with vitamin C may ameliorate this stress and also may improve the oxidative balance in the liver.

Purpose: Urinary cytokine changes may serve as biomarkers to assess treatment outcomes for interstitial cystitis/bladder pain syndrome (IC/BPS). This study analyzed the changes in urinary cytokines following various bladder therapies and explored their clinical significance in therapeutic mechanisms.
Methods: A total of 122 patients with IC/BPS treated with platelet-rich plasma (PRP), botulinum toxin-A (BoTN-A), hyaluronic acid (HA), or low-energy shock wave (LESW) were evaluated.

The kidneys have a regulatory role in many diseases with their diuresis function and capacity to maintain electrolyte balance. In case of extensive damage, the kidney's filtration capacity is impaired and cannot fulfill its functions. Fluvoxamine (FLV), an antidepressant agent, has antioxidant and anti-inflammatory effects.
