Oral calcium and calcium plus vitamin D supplements are commonly prescribed to several groups of patients, e.g., osteoporosis, fracture, and calcium deficiency.
Acute ischemia-reperfusion (I/R) injury is a leading cause of acute renal failure, characterized by endothelial cell dysfunction and microvascular injury, and EPO has shown protective effects in prior models of I/R injury.
This study aimed to explore whether EPO administration could protect against renal failure caused by I/R injury in rats by enhancing the mobilization of endothelial progenitor cells (EPCs) and promoting blood vessel formation (neovascularization).
Results indicated that EPO treatment improved renal function, reduced tubular damage, and increased levels of markers for EPCs and angiogenesis compared to the I/R group without EPO.
Contrast-induced nephropathy (CIN) is a major cause of acute kidney injury in hospitals, linked to oxidative stress caused by intravenous radiocontrast agents.
A study was conducted on male rats to assess the effects of alpha-tocopherol (a form of Vitamin E) on reducing kidney damage from CIN, with various groups receiving different doses prior to CIN induction.
Results showed that alpha-tocopherol significantly improved renal function, reduced oxidative stress markers, and prevented kidney damage, suggesting its potential as an antioxidant therapy for CIN.
