OBJECTIVE: The purpose of this study was to identify the effect of EMG-triggered electrical neuromuscular stimulation for recovery of hemiplegic arm function. METHOD: EMG-triggered electrical stimulation was applied to the extensor digitorum communis (EDC) of 8 chronic hemiplegics who showed no functional changes for more than 3 months. Stimulation was started when the amplitude of processed EMG signal from the same muscle exceeded the preset threshold. The therapeutic effect was evaluated by kinesiologic and clinical methods before and after 4 weeks. Quantitative EMG from EDC, excursion of second metacarpophalangeal joint, and functional measurements were used. We also evaluated cognitive and perceptual effect on recovery of arm function. RESULTS: Subjects treated with EMG-triggered electrical stimulation showed significant gain in amplitude of quantitative EMG and excursion sum during maximal exertion comparing to those of pre-treatment (p<0.05). There was also an decrease of spasticity after treatment. But functional, perceptual and cognitive outcome were not changed significantly (p>0.05). CONCLUSION: These results suggest that EMG-triggered electrical stimulation might be an effective therapeutic modality to improve motor function of the hemiplegic arm of chronic brain injured patients.

This study was conducted to investigate the effects of powdered young barley leaf and its water extract on body weight and lipid metabolism in high-fat fed mice. Male mice were divided into normal group, high-fat (HF) group, highfat group supplemented with powdered young barley leaf (HF-YBL) and high-fat group supplemented with water extract of the powdered young barley leaf (HF-WYBL). The powdered young barley leaf or its water extract was added to a standard diet based on 1% dried young barley leaf (1 g YBL/100 diet and 0.28 g WYBL/100 g diet) for 8 weeks. Supplementation of YBL and WYBL significantly reduced body weight and epididymal adipose tissue weight in highfat fed mice. Food intake and daily energy intake were significantly lower in the YBL group than in the HF group. After 8 weeks, plasma triglyceride and cholesterol concentrations were significantly higher in the HF group than in the Normal group; however, both YBL and WYBL significantly lowered those of the high-fat fed mice. The ratio of HDL-cholesterol/ total cholesterol of the YBL and WYBL groups were significantly elevated compared to that of HF group. Both YBL and WYBL significantly increased fecal excretion of triglyceride in high-fat fed mice, whereas they did not affect fecal cholesterol concentration. The triglyceride levels of liver, adipose tissue and heart were significantly lower in the YBL and WYBL groups than in the HF group. Supplementation of WYBL also lowered the kidney triglyceride and heart cholesterol concentrations compared to those of HF group. Hepatic lipid regulating enzyme activities, fatty acid synthase, HMG-CoA reductase and acyl-coenzyme A: cholesterol acyltransferase, were significantly lower in the YBL and WYBL groups than in the HF group. Accordingly, these results suggest that YBL and WYBL improve plasma and organ lipid levels partly by increasing fecal lipid excretion and inhibiting fatty acid and cholesterol biosynthesis in the liver.

As 16S ribosomal RNA (rRNA)-targeted sequencing can detect DNA from non-viable bacteria, it can be used to identify pathogens from clinical samples even in patients pretreated with antibiotics. We compared the results of 16S rRNA-targeted sequencing and culture for identifying bacterial species in normally sterile body fluid (NSBF): cerebrospinal, pericardial, peritoneal and pleural fluids. Over a 10-year period, a total of 312 NSBF samples were evaluated simultaneously using 16S rRNA-targeted sequencing and culture. Results were concordant in 287/312 (92.0%) samples, including 277 (88.8%) negative and 10 (3.2%) positive samples. Of the 16 sequencing-positive, culture-negative samples, eight showed clinically relevant isolates that included Fusobacterium nucleatum subsp. nucleatum, Streptococcus pneumoniae, and Staphylococcus spp. All these samples were obtained from the patients pretreated with antibiotics. The diagnostic yield of 16S rRNA-targeted sequencing combined with culture was 11.2%, while that of culture alone was 6.1%. 16S rRNA-targeted sequencing in conjunction with culture could be useful for identifying bacteria in NSBF samples, especially when patients have been pretreated with antibiotics and when anaerobic infection is suspected.
