RESUMO
Mycoplasma pneumoniae is one of the common pathogens of community-acquired pneumonia, which not only can cause respiratory performance, but also can cause extrapulmonary performance.Among them, arteriovenous embolism is difficult to identify early, lacking specific clinical manifestations.Once embolism occurs in the heart, lung, brain, etc, the condition is critical and can cause death or disability in a short time, which greatly threatens children′s health.Thrombosis is often accompanied by an increase in D-dimer, but the level of D-dimer fluctuates greatly.Therefore, it is still difficult to identify and diagnose the hypercoagulable state early in the clinic and evaluate the risk factor of thrombosis.
RESUMO
Object To develop a best approach for the rapid propagation of Lilium brownii F.E. Brown var. viridulum Baker by tissue culture. Methods Different parts of the bulb were tried as the explant and cultured on different culture media with the additon of different portions of various hormones at various cultural conditions. Results The best medium for the culture of explant bulb was MS+NAA 0.5 mg/L and GA 3 2.0 mg/L and the highest induction rate was at the lowest part of the scale leaves, which attained 92.5%. The small bud can further differentiate to form secondary small buds. By liquid-quivering culturing, the weight increase can be accelerated. Conclusion Tissue culture of L. brownii var. viridulum can achieve its rapid propagation, resulting in the possibility for its industrial production.
