  • PURPOSE: This study examined the efficacy of an interferential current (IFC) treatment on the improvement of pain, disability, and quality of life in stroke patients with lumbago. METHODS: A double-blind, randomized clinical trial was conducted on 40 stroke patients with lumbago. The patients were allocated randomly into two groups: the IFC treatment group (n= 20) and the placebo treatment group (n= 20). The IFC group received 30 minutes of IFC treatment on the lumbar region, while the placebo group received IFC treatment but without real electrical stimulation. The intervention was administered five days a week for four weeks. The primary outcomes of pain intensity were measured using a visual analogue scale. The secondary measurements included the Barthel Index, Oswestry Disability Index (ODI), and health-related quality of life (HRQoL). RESULTS: The measurements were conducted before and after the two-week intervention period. Compared to the placebo treatment group, the IFC treatment group showed significantly greater improvement in the pain intensity (p<.05), ODI (p<.05), and SF-36 (p<.05) at the end of the intervention. No significant differences in the Barthel Index were found between the two groups. CONCLUSION: These findings show that an IFC treatment can improve pain, functional ability, and quality of life, highlighting the benefits of somatosensory stimulation from IFC in stroke patients with lumbago.

  • In the present study, the author investigated to the cytotoxocity in cultured rat hepatocytes of Viscum album lectin. The cytotoxcity effect in Viscum album lectin on the activity of LDH was also investigated. Viscum album lectin significantly increased LDH leakage into medium of hepatocytes treated or untreated with $CCl_4$ (p<0.001). However, Viscum album lectin significantly increased LDH leakage from $CCl_4$-induced hepatocyte (p<0.001). There was a significant increase in LDH levels relative to the control group. Histological observation basically supported the result obtained from LDH assay. The livers of rats challenged with $CCl_4$ produced a marked increased cytoplasmic vacuoles and inflammatory cells in number, while the number of necrotic cells and swollen hepatocytes did not change significnatly. Rats administered DMSO alone did not alter the normal hepatic architecture. Histological observation of liver section in rat treated 72 hrs with either Viscum album lectin $CCl_4$-induced liver damage showed number of cytoplasmic vaculoe and necrotic cell. The number of inflammatory cell increased markedly. This results suggest to the conclusion that Viscum album lectin has a effect of hepatotoxicity activator.
