Unlabelled: Serum anti-oxidative barrier is a factor determining active oxygen form suppression. The aim of this study is to investigate superoxide dismutase (SOD) and glutathione peroxidase (GP) serum level changes as a marker of its enzymatic barrier efficiency in patients with acute pancreatitis (AP) evaluated by means of Ranson score.
Material And Methods: Fifty patients with AP were divided onto 2 groups. Group 1 consisted of 22 patients with moderate AP, whose overall standing varied from 3 to 6 points according to Ranson. Group 2 was made of 28 patients with severe AP and 6 or more Ranson scores. Serum activities of SOD and GP were measured on 1st, 3rd 7th, and 10th day of treatment using Martin oxidation method in the former, and Rice-Evans spectrophotometry method in the latter case.
Results: Blood SOD activity in Group 1 patients underwent gradual normalization; however in all time intervals it remained statistically higher than in Group 2. The activity of GP was lower than normal in both groups. In moderate AP patient group GP activity differences became statistically significant as late as on the 7th and 10th day of study. Both patient groups differed significantly regarding the GP serum activity. Serum anti-oxidative barrier activity in patients with severe AP was significantly lower than in patients with moderate form of the disease.
Conclusions: Along with patient amelioration and inflammation regression the activity of anti-oxidative serum enzymes increased. The estimation of anti-oxidative stress parameters may be useful in disease dynamics monitoring which affects treatment modality.

Background: Acute lung injury (ALI) is characterized by diffuse alveolar injury and acute non-cardiac pulmonary edema, with high morbidity and mortality. Lysophosphatidylcholine 14:0 (LPC14:0) has anti-inflammatory and anti-oxidative effects in sepsis and bacteremia. We hypothesized that LPC14:0 could be a potential treatment for ALI.

Article Synopsis
- Bronchial asthma is a common chronic respiratory condition in children that affects their overall quality of life due to exacerbations and persistent symptoms.
- The management of asthma has focused on improving lung function early in childhood to prevent long-term health issues, as early deficits can lead to significant problems in adulthood.
- Antioxidants play a crucial role in managing asthma by balancing oxidative stress in the lungs, and this review highlights the complex interactions between oxidative and antioxidative factors, pointing to future therapeutic approaches.

Purpose: The purpose of this study was to evaluate the cytoprotective effect and the mechanism of cRGD-conjugated bilirubin nanoparticles (cNPs@BR) in dry eye disease (DED).
Methods: The binding capacity and cellular uptake of cNPs@BR in human corneal epithelial cells (HCECs) were assessed by immunofluorescence. The anti-inflammation and anti-oxidative stress effects of cNPs@BR were determined by flow cytometry, immunofluorescence, Western blot, chromatin immunoprecipitation (ChIP), and ELISA assay in LPS-stimulated RAW264.

Background: Diarrhea and intestinal dysfunction commonly occur in young mammals, causing malnutrition and growth retardation in both human and livestock. As the traditional Chinese herb, mulberry leaf contains various bioactive compounds and showed several health benefits, such as regulating glucose and lipid metabolism, and modulating gut microbiota. Mulberry leaf exhibits the potential to modulate redox homeostasis and improve gut health, but the function and underlying mechanisms remains elucidative.
