AP was induced in rats by L-arginine (2.5 g/kg) injections (two doses given at 1-h interval). The protective groups were pre-treated with either vitamin E (60 mg/kg) or metformin (50 mg/kg) prior to L-arginine injections and continued on these medications until being sacrificed. AP markedly decreased the density of zymogen granules in pancreatic acinar cells (44.5 ± 2.2% in control versus 9.2 ± 1.9% in AP), alongside tissue damage and a significant (p < 0.0001) increase in biomarkers of nitrosative stress (iNOS), inflammation (IL-6 and TNF-α mRNA), and pancreatic injury (amylase, lipase, LDH, and MPO). All these parameters were significantly (p ≤ 0.0005) protected by vitamin E and metformin, with vitamin E providing greater protection for pancreatic glycoprotein zymogens and serum amylase. Thus, AP is associated with the destruction of the glycoprotein zymogens, which is differentially protected by vitamin E and metformin.","PeriodicalId":8331,"journal":{"name":"Archives of Physiology and Biochemistry","volume":" ","pages":"1-10"},"PeriodicalIF":2.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male athletes experience testicular atrophy, temporary suppression of spermatogenesis, hypogonadism, reduced fertility, infertility, and hormonal imbalance. In contrast, women experience ovarian dysfunction and menstrual irregularities. In the kidney, steroids lead to increased inflammatory cytokines, fibrosis, renal tubular hypertrophy, glomerular changes, and structural damage, and show higher levels of serum creatinine, urinary protein, and cystatin C.

BOL attenuated both cardiac hypertrophy and increased diastolic volume caused by adrenergic overstimulation (P < 0.05).
