Antioxidant Activity of Water Extract from Fermented Mycelia of Cordyceps sobolifera (Ascomycetes) in Caenorhabditis elegans.

This research aimed to evaluate the potential of Cordyceps sobolifera in mycelial biomass production via liquid culture and to assay the safety and determine the antioxidative and antiaging activities of Caenorhabditis elegans. A C. sobolifera isolate was cultured using the one-factor-at-a-time method to illustrate its carbon and nitrogen requirements.

[Study on biological characteristics of Cordyceps ramosa mycelia].

Objective: To study the biological characteristics of Cordyceps ramosa mycelia.

Methods: The effects of temperature, pH, carbon source, nitrogen source and C/N ratio on the mycelial growth of Cordyceps ramosa were investigated.

Results: The optimum temperature, pH, carbon source, nitrogen source and C/N ratio for the mycelial growth were 25 degrees C, 5.

Safety assessment of Cordyceps guangdongensis.

Cordyceps guangdongensis as a kind of fungus, has been discovered and cultivated successfully in recent years. However, its safety assessments have not been studied. In this report, a serial of tests for toxicological safety assessments were depicted in details.

[Transbronchoscopic balloon detection and selective bronchial occlusion for intractable pneumothorax].

Objective: To evaluate the effect, complications and safety of transbronchoscopic balloon detection (TBD) and selective bronchus occlusion (SBO) for intractable pneumothorax.

Methods: Forty cases of pneumothorax from 5 teaching hospitals in Fujian province were included for this study. TBD was performed in all the 40 cases for whom chest tube drainage had lasted for more than 7days but failed to close the pleura fistulae.
