滇青冈(Cyclobalanopsis glaucoides)内生菌及根际土壤微生物的初步研究

实验对滇青冈根、茎、叶的内生菌及根际土壤微生物进行了初步研究,结果表明:从滇青冈根、茎、叶及根际土壤中分离出细菌61株,真菌24株,共85株。根中分离出了29株,包括25株细菌,4株真菌;茎中12株,包括4株细菌,8株真菌;叶中7株,包括3株细菌,4株真菌,即根(34%)>茎(14%)>叶(8%),其余37株都是从土壤中分离出来的。细菌在滇青冈体内分布情况为根(56%)>茎(8%)>叶(6%),真菌则是茎中较多。从根、茎、叶中分离出的细菌多为球菌,根际土壤中分离出的则是杆菌较多,二者分离出的菌株都是G+占优势。分离出的真菌包括2株曲霉属真菌、2株枝孢属、1株凸脐蠕孢属、1株葡萄孢属、1株炭疽菌属、4株青霉属、2株团黑孢霉属,其他的为无孢类群,其中青霉属真菌略占优势。实验结果为滇青冈的化感作用研究提供部分数据支持。

Regional cerebral blood flow imaging assessment of brain function reconstruction in elderly hemiplegia patients by body weight support treadmill training

The mechanism underlying body weight support treadmill training in elderly hemiplegic stroke patients is largely unknown. This study aimed to elucidate the changes of cortical blood flow in seven elderly patients with post-stroke hemiplegia before and after body weight support treadmill training by semi-quantitative analysis of regional cerebral blood flow assessed by single photon emission computed tomography. Body weight support treadmill training for 6 months was effective in improving cerebral blood flow and promoting the walking speed and balance recovery in elderly patients with post-stroke hemiplegia.
