Activity of plasma proteolytic systems was studied in outbred albino rats with acute renal failure. The possibility of treating this disorder with acute phase protein alpha-1-acid glycoprotein was evaluated. Acute renal failure was induced by single subcutaneous injection of mercury chloride (II). The parameters were evaluated on day 5 postinjection. alpha-1-Acid glycoprotein in a dose of 150 mg/kg was administered 3 times. Acute renal failure was accompanied by activation of the complement system and fibrin formation (with factors for the intrinsic and common pathways of blood coagulation) and inhibition of the fibrinolytic system and antithrombin activity. Treatment with glycoprotein was followed by partial recovery of fibrin formation and complement system. These changes were probably related to accumulation of glycoprotein in the renal tissue and in situ protective effect.

Impact of intrarenal arterial lesions on prognosis of IgA nephropathy: insights from a retrospective cohort study.
Ren Fail
December 2025
Department of Nephrology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang, People's Republic of China.
Background: IgA nephropathy (IgAN) presents a challenging spectrum of outcomes, often complicated by intrarenal arterial/arteriolar lesions (IALs) in affected individuals. Despite their clinical relevance, existing criteria for classifying and assessing the severity of these lesions remain undefined. This study aimed to establish semi-quantitative assessment criteria for grading IALs and to evaluate their prognostic significance in patients with IgAN.

Compartment syndrome is an orthopaedic emergency with moderate-to-severe sequela (pain, muscle contracture, nerve damage, infection, rhabdomyolysis, renal failure, etc.) if inadequately treated and can be difficult to diagnose in a timely fashion. Further complicating timely diagnosis are atypical presentations resulting in compartment syndrome.
