13 results about "Serum urea" patented technology

Serum urea is detected in the blood. During the metabolism of protein in the body, the liver creates ammonia, which is broken down into a by-product called urea. Kidneys filter excess urea into the urine and in sweat, but some goes into the bloodstream as serum urea.

Use of quinolinic acid in the preparation of drugs for preventing and treating acute kidney injury

This invention discloses the application of quinolinic acid in the preparation of drugs for the prevention and treatment of acute kidney injury (AKI). AKI refers to acute kidney injury induced by renal ischemia-reperfusion. The drug is an oral formulation used for prophylactic administration in high-risk individuals undergoing iatrogenic procedures at potential AKI risk, and for pretreatment of ischemic conditions in transplanted kidneys. Experiments have shown that administration of quinolinic acid significantly reduces serum urea nitrogen levels in AKI mice, alleviates renal tissue morphological damage in AKI mice, and reduces the expression level of the renal tubular injury factor NGAL protein in AKI mice, demonstrating significant clinical value in the prevention and treatment of AKI.

A method for constructing a rat hyperuricemia model

PendingCN122537387AXanthineRat model
This invention provides a method for constructing a rat model of hyperuricemia, belonging to the field of animal model construction technology. SPF-grade male rats were selected and, after adaptive feeding, were administered inosine (5-15 mg / kg), potassium oxonate (150-160 mg / kg), and hypoxanthine (100-200 mg / kg). Inosine and potassium oxonate were administered intraperitoneally, while hypoxanthine was administered subcutaneously. Experimental results showed that serum uric acid levels significantly increased one hour after modeling, and the hyperuricemic state could be maintained for up to 24 hours, significantly better than traditional models. Simultaneously, serum urea nitrogen and creatinine levels did not show significant increases, indicating that the model did not cause serious kidney damage. The hyperuricemia model constructed by this invention has a rapid onset of action, a long duration of hyperuricemia, and minimal kidney damage, making it suitable for the screening and evaluation of anti-hyperuricemia drugs.
