16 results about "Hyperammonemia" patented technology

Hyperammonemia is a metabolic disturbance characterised by an excess of ammonia in the blood. It is a dangerous condition that may lead to brain injury and death. It may be primary or secondary. Ammonia is a substance that contains nitrogen. It is a product of the catabolism of protein. It is converted to the less toxic substance urea prior to excretion in urine by the kidneys. The metabolic pathways that synthesize urea involve reactions that start in the mitochondria and then move into the cytosol. The process is known as the urea cycle, which comprises several enzymes acting in sequence.

Composite hydrogel system as well as preparation method and application thereof

The invention discloses a composite hydrogel system as well as a preparation method and application thereof, and belongs to the technical field of biological medicines. The preparation method comprises the following steps: jointly encapsulating chlorella and sodium phenylbutyrate in semi-interpenetrating network hydrogel formed by cross-linking carboxymethyl chitosan and sodium alginate through genipin, so as to prepare a composite hydrogel system with an oral administration function. The hydrogel system has good colon targeted release characteristics and pH responsiveness, can prolong the retention time of drugs in gastrointestinal tracts, protects chlorella from being damaged by gastric acid and enzymolysis, realizes dual-channel removal of ammonia, and effectively inhibits growth of colorectal cancer. The system can regulate intestinal microbiota, enrich beneficial bacteria such as ackermann muciniphile and improve the intestinal microenvironment. The hydrogel system is good in biocompatibility, high in long-term oral administration safety, wide in raw material source, low in cost, simple in preparation process and easy for large-scale production, and has an important clinical application prospect in the field of combined treatment of hyperammonemia and colorectal cancer.
