查询词典 propagation of disease

According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

Nowadays, bone defect has become one of the most important disease which threat people's living quality severely. Today, the most common methods used to healing bone defects include: Autogenous bone grafts and allogenic bone grafts. But autogenous bone grafts have a shortage on donor, difficult to make shape and will bring a complicate disease on donor site; allogenic bone grafts often follow with graft rejective reaction, and have a potential risk of propagation of many disease.

目前，主要应用于临床骨缺损修复的方法有自体骨移植和异体骨移植等，但自体骨移植存在材料来源有限、供骨部位的损伤以及塑形困难等问题；异体骨移植也有潜在的疾病传播隐患以及移植排斥反应等严重后果，因此无论自体骨移植还是异体骨移植均无法完全满足需求，临床急需寻找一种安全有效的骨移植替代材料。
