Résumé
A 54-year-old man was admitted to respiratory department with chief complaints of recurrent cough and dyspnea. Chest imaging showed multiple patchy shadows and interstitial changes. Evidence of infectious diseases was not definite, and antibiotic treatments were not effective. In the meantime, myelodysplasia syndrome was diagnosed with pancytopenia. The pathologic findings of transbronchoscopic lung biopsyshowed chronic inflammatory interstitial changes, suggesting a clinical diagnosis of organizing pneumonia. After glucocorticoids treatment, his condition aggravated. The second percutaneous lung biopsy showed the infiltration of a large number of neutrophils. Therefore, the final diagnosis of myelodysplasia syndrome with Sweet syndrome was made. Then glucocorticoids and supportive treatment were given This case may improve physicians' understanding of myelodysplasia syndrome complicated with Sweet syndrome.
Résumé
In order to enhance the utilization efficiency, reduce the environmental pollution of traditional chemical treatment and the agriculture waste incineration; we studied the ligninase production by Coprinus comatus, Aspergillus niger and Trichoderma reesei through the plate screening. The results showed that C. comatus mixed culture with T. reesei have a good compatibility and higher yields of Laccase. On the basis of this pre-experiment, we studied the optimal conditions of mixed culture for enzyme production. Under the optimal conditions: the inoculation proportion of C. comatus and T. reesei (5:2), the interval of time (12 h), the temperature 260C, the shake rotation speed 150 r/min, fermented for 3 days, the Laccase activity reached 3267.1 U/mL, increased by 106% contrasted with single culture of C. commatus.
