Resting-state fMRI studies in epilepsy.

Epilepsy is a disease characterized by abnormal spontaneous activity in the brain. Resting-state functional magnetic resonance imaging (RS-fMRI) is a powerful technique for exploring this activity. With good spatial and temporal resolution, RS-fMRI is a promising approach for accurate localization of the focus of seizure activity.

[Study on physiological characteristics of seed germination of Ephedra sinica].

Objective: To study the characteristics of the Ephedra sinica seed germination, to provide a basis for its cultivation.

Methods: The seed germination inhibitive substances were studied by water washing method; the seed vigor was determined by TTC method and red ink method, the influence of growth substances to seed germination was studied by agar medium cultivation, and the influence of different sand burying depth on seed germination was studied by sand medium cultivation.

Results: The seed germination rates of dry seeds, seeds as 12 h soaking with distilled water, 12 h washing by water and with ensheathe phyllary were 44%, 61%, 79.
