Mechanical Enhancement of the Gelatin/Poly(zinc acrylate) Hydrogel Stent in Bile.

Hydrogels with the features of softness, biocompatibility, and modifiability have emerged as excellent materials in the biomedical field. However, the poor mechanical properties of the hydrogels limit their further practical applications. Double-network and metal ion coordination, such as Cu and Zn, have achieved a significant reinforcement of the mechanical strength of the hydrogels.

Antitumor effects and chemical compositions of Eupolyphaga sinensis Walker ethanol extract.

Ethnopharmacological Relevance: Eupolyphaga sinensis Walker popularly known as "preferred drug to regulate blood flow" are traditionally used in folk medicine in the treatment of ecchymoma, posttraumatic wound, hepatic fibrosis and tumor.

Aim Of The Study: To characterize chemical compositions and to evaluate the antitumor and immunomodulatory of Eupolyphaga sinensis Walker ethanol extract (ESEE) in hepatocarcinoma H(22) bearing mice.

Materials And Methods: ESEE was obtained by ethanol reflux extraction and analyzed by gas chromatography-mass spectrometry (GC-MS) after methylation.

Chemical compositions and anti-influenza activities of essential oils from Mosla dianthera.

Ethnopharmacological Relevance: Mosla dianthera as an aromatic herb is used in folk medicine for the treatment of cough, colds, fever, bronchitis, nasal congestion and headache.

Aim Of The Study: To characterize chemical compositions and to evaluate the anti-influenza effects of essential oils of M. dianthera (MDEO) in influenza virus A (IVA) infected mice.

[Effect of gamma-interferon on hepatic granuloma formation in mice infected by cysticerci of Taenia saginata asiatica].

Immunohistochemical streptavidin biotin-peroxidase complex method was used to investigate the effect of gamma-interferon (IFN-gamma) on the hepatic granuloma formation and liver fibrosis in mice infected with Taenia saginata in Duyun area of Guizhou Province. The results reveal contrary relation between the level of IFN-gamma in the liver and the degree of liver fibrosis (p<0.01).
