The purpose of this study was to determine the distribution of referred pain from the cervical zygapophyseal joints (C0/1 to C7/Th1) and the cervical dorsal rami (C3 to C7). The subjects were 61 patients who had occipital, neck, and shoulder pain of suspected zygapophyseal origin in whom pain was reproduced by injection of contrast medium into the joints or(More)
Recently, an isomeric mixture of herbal anti-inflammatory naphthoquinones shikonin and alkannin, and their derivatives, have been found to impair cellular responses involving nitric oxide (NO) and NO synthesis, like the acetylcholine-induced relaxation response of rat thoracic aorta and NO release from murine RAW 264.7 macrophages. However, the mechanisms(More)
Shikonin, an anti-inflammatory compound of "Shikon", inhibits the neutrophil superoxide (O2 (•-)) generation by NADPH oxidase 2 (Nox2); however, the mechanisms of how shikonin affects Nox2 activity remained unclear. We aimed to elucidate the relationship between the inhibition of Nox2 activity and influences on intracellular Ca(2+) concentration ([Ca(2+)]i)(More)
We examined a 35-year-old male patient with recurrent tonsillitis who did not respond to operation and drug therapy and we treated him by stellate ganglion block (SGB) alone. The clinical symptoms improved by the SGB. There was no subsequent recurrence. The result suggests that SGB therapy is effective for recurrent tonsillitis.
Continuous epidural block is often used for the treatment of pain. But there have been unsuccessful cases by the routine blind method. We devised a modified method of administering continuous epidural block under prone position with fluoroscopic guidance. The purpose of this study was to evaluate the utility of our modified method. There were 18 cases with(More)
To our knowledge, this is the first report of high-frequency thermocoagulation applied to the spinal root. We treated 34 patients suffering from cancer pain with this technique. Among these patients, cancer pain occurred due to intrapelvic metastasis in 11 patients, and 13 complained of chest pain due to cancer. Every patient was considered to have good or(More)
OBJECTIVES Japan has actively reclassified substances ranging from prescription drugs to over-the-counter (OTC) drugs in recent years. The sale of most OTC drugs was deregulated several times and pharmacists' supervision was deemed no longer mandatory. Japan established a new OTC evaluation system in 2015 to hear opinions from various stakeholders regarding(More)
We examined a 5-year-old boy with allergic rhinitis, chronic sinusitis, atopic dermatitis, and tendency to suffer common cold, who responded to stellate ganglion block (SGB). SGB therapy was extremely effective for this patient. The result suggests that SGB therapy should be performed on patients with allergic diseases resistant to drug and diet therapy.(More)
Kampo medicines must be used according to an individual's physical characteristics and symptoms to avoid lack of efficacy, adverse reactions or interactions with other drugs. As category-2 over-the-counter drugs (OTCs), Kampo OTCs are not targets of active explanations by pharmacists, and consumers usually decide to use OTCs by themselves on the basis of(More)
