松萎蔫病是一种非常复杂的病害。据报道,松材线虫(Bursaphelenchus xylophilus)及其携带的细菌诱导了该病,但是对于细菌的的作用尚存争议。笔者筛选出杀细菌剂进行了温室和林间防治松萎蔫病的实验。利用每株3年生赤松(Pinus densiflora)注射3mg的恶喹酸,松萎蔫病防效达到71%。利用恶喹酸或阿维菌素及两者混合物对大约20年生赤松的试验表明,3种处理均显示了很高的防效。以上结果证明伴生细菌是诱导松萎蔫病的必要因素,对松萎蔫病可利用杀细菌剂或杀细菌剂与杀线剂混合物进行防控。

Perspectives on the neural connectivity of the fornix in the human brain

引用

Neural Regeneration Research 2014年第15期9卷 1434-1436页

作者： Sung Ho Jang hyeok Gyu kwon Department of Physical Medicine and Rehabilitation College of MedicineYeungnam UniversityTaeguRepublic of Korea

The fornix is involved in the transfer of information on episodic memory as a part of the Papez circuit. Diffusion tensor imaging enables to estimate the neural connectivity of the fornix. The anterior fornical body has high connectivity with the anterior commissure, and brain areas rele- vant to cholinergic nuclei （septal forebrain region and brainstem） and memory function （medial temporal lobe）. In the normal subjects, by contrast, the posterior fornical body has connectivity with the cerebral cortex and brainstem through the splenium of the corpus callosum. We believe that knowledge of the neural connectivity of the fornix would be helpful in investigation of the neural network associated with memory and recovery mechanisms following injury of the fornix.

Improvement of ataxia in a patient with cerebellar infarction by recovery of injured cortico-ponto-cerebellar tract and dentato-rubro-thalamic tract: a diffusion tensor tractography study

引用

Neural Regeneration Research 2019年第8期14卷 1470-1472页

作者： Sung Ho Jang hyeok Gyu kwon Department of Physical Medicine and Rehabilitation College of Medicine Yeungnam University Daegu Republic of Korea Department of Physical Therapy College of Health Science Eulji University Gyeonggi Republic of Korea

Coordinated movement is generated by communication between the cerebrum and cerebellum via the cerebellar peduncles (CPs). The CPs are classified into three types (superior, middle, and inferior), and each includes a variety of neural tracts. Among those tracts, the cortico-ponto-cerebellar tract (CPCT), a middle CP, is involved in motor planning and initiation of movement, while the dentato-rubro-thalamic tract (DRTT), a superior CP, is involved in motor coordination, movement timing, verbal fluency, and working memory (Kase et al., 1993.

Delayed degeneration of an injured spinothalamic tract in a patient with diffuse axonal injury

引用

Neural Regeneration Research 2017年第11期12卷 1927-1928页

作者： Sung Ho Jang hyeok Gyu kwon Department of Physical Medicine and Rehabilitation College of MedicineYeungnam UniversityDaemyungdongNamkuDaeguRepublic of Korea Department of Physical Therapy College of Health SciencesCatholic University of PusanPusanRepublic of Korea

Diffuse axonal injury （DAI） is one of the devastating mechanisms of traumatic brain injury （TBI） and shows extensive sub- cortical lesions due to shearing forces induced by rapid acceleration-deceleration and rotation of the brain （Adams et al., 1982; Meythaler et al., 2001）. As a result, conventional brain imaging techniques including brain MRI have been limited in demon- strating neuronal degeneration in patients with DAI. However, diffusion tensor tractography （DTT）, which is derived from diffusion tensor imaging （DTI） has enabled three-dimensional reconstruction of the neural tracts （Jang and Seo, 2014）. Since the introduction of DTI, several studies have demonstrated neuronal degeneration after TBI （Tomaiuolo et al., 2005; Hong and lang, 2010; kwon and Jang, 2014）. However, little is known about delayed neuronal degeneration in patients with TBI.
