Keishibukuryogan is a Kampo medicine that induces vasodilation and improves the blood flow velocity in subcutaneous blood vessels. We herein report two cases in which keishibukuryogan completely diminished subcutaneous hematoma after cardiac resynchronization therapy pacemaker implantation and defibrillator battery replacement within a month. Keishibukuryogan can be a good option for treating or preventing subcutaneous hematoma after surgical procedures for devices.

The rapid assessment of gene function is crucial in biological research. The CRISPR/Cas9 system is widely used as a tool for targeted gene editing in many organisms including plants. Previously, we established a transient gene expression system for investigating cellular circadian rhythms in duckweed. In this system, circadian reporters and clock gene effectors—such as overexpressors, RNA interference (RNAi), and CRISPR/Cas9—were introduced into duckweed cells using a particle bombardment method. In the present study, we applied the CRISPR/Cas9 system at a single cell level to Arabidopsis thaliana, a model organism in plant biology. To evaluate the mutation induction efficiency of the system, we monitored single-cell bioluminescence after application of the CRISPR/Cas9 system targeting the ELF3 gene, which is essential for robust circadian rhythmicity. We evaluated the mutation induction efficiency by determining the proportion of cells with impaired circadian rhythms. Three single guide RNAs (sgRNAs) were designed, and the proportion of arrhythmic cells following their use ranged from 32 to 91%. A comparison of the mutation induction efficiencies of diploid and tetraploid Arabidopsis suggested that endoreduplication had a slight effect on efficiency. Taken together, our results demonstrate that the transiently introduced CRISPR/Cas9 system is useful for rapidly assessing the physiological function of target genes in Arabidopsis cells.
