There is ongoing research on treatments that promote antioxidant and anti-inflammatory mechanisms, which will reduce mortality in sepsis. In this study, we compared the anti-inflammatory and antioxidant activities of quercetin and ascorbic acid using a sepsis model induced in infant rats. ⋯ The antioxidant activity, which is impaired in sepsis, was increased by both molecules. We observed that these two molecules, which are free of side effects, have a positive influence on the progression of sepsis to severe and fatal sepsis in childhood (Tab. 2, Ref. 38).

Vascular endothelial growth factor (VEGF) is a signalling protein of critical importance for angiogenesis. In an effort to better understand its significance in hypertension-induced injury of the heart and kidney we aimed at studying the changes in its expression in an experimental model and correlated it with capillary density in the myocardium and the renal parenchyma. ⋯ These findings underscore the key significance of VEGF for compensatory angiogenesis and suggest that a statistically significant depletion of these vascular adaptive mechanisms is a major aspect in the cascade of hypertension-induced injury of the heart and kidney (Tab. 3, Fig. 26, Ref. 47).

Cisplatin is commonly used in the treatment of lung, genitourinary, and gastrointestinal cancers. Peripheral neuropathy is the most important side effect, leading to a decrease in the dose of cisplatin or its complete cessation in the early period. 16 rats were given cisplatin at a dose of 2.5 mg/ kg/day twice a week for 4 weeks to induce neuropathy model. The rats taking Cisplatin were divided into 2 groups. ⋯ Besides, histological examinations showed an increase in axon diameter and NGF expression with Propofol treatment. This study demonstrated that Propofol exerts protective activity against cisplatin-induced neurotoxicity by increasing endogenous antioxidants and reducing lipid peroxidation and inflammation (Tab. 3, Fig. 4, Ref. 30).

Malate, the tricarboxylic acid (TCA) cycle intermediary, upregulates renal nitric oxide (NO) signaling, and NO is renoprotective in nephropathy. ⋯ Malate ameliorated the injury and inflammation but selectively reduced fibrosis in obstructive nephropathy (Fig. 6, Ref. 32).
