However, it has not been clarified whether limaprost affects pain sensation associated with radiculopathy due to lumbar spinal stenosis (LSS). The aim of this study was to compare the efficacy of oral limaprost with nonsteroidal anti-inflammatory drugs (NSAIDs) for radiculopathy.
We performed a multicenter prospective randomized trial. Patients with LSS who had radicular-type
neurologic intermittent claudication assessed based on a self-reported diagnostic support tool were randomized into three treatment groups. Limaprost, NSAIDs, or limaprost plus NSAIDs were administered orally for 6 weeks. Leg pain, low back pain (LBP) and the associated symptoms were assessed by a numerical rating scale (NRS) both at rest and on movement as well as the Roland-Morris Disability Questionnaire (RDQ) and Short Form (SF)-36.
Sixty-one patients were enrolled in the study. Each treatment finally reduced radicular Epigenetic inhibitor chemical structure pain, and the improvement was prominent in a combination treatment. There were no significant differences in radicular pain among three groups at final follow-up. LBP was not influenced by selleck kinase inhibitor limaprost, and a significant reduction of LBP and RDQ was confirmed in a combination treatment compared with limaprost. Physical function of the SF-36 subscales after a combination
treatment showed a marked alleviation compared with NSAIDs.
These obtained findings suggest that the effects of limaprost seem to be limited to radicular pain, not for LBP. Overall, a combination treatment might be more effective in the management of radiculopathy induced by LSS than SN-38 molecular weight monotherapy with either agent.”
“The chemical composition and free radical scavenging properties of the MeOH extract of Hypericum richeri
and its subsequent CHCl3, n-BuOH, EtOAc and aqueous extracts were investigated. Four quercetin-3-O-glycosides, three myricetin-3-O-glycosides, 3-O- and 5-O-caffeoylquinic acid, quercetin, I3,II8-biapigenin, pseudohypericin and hypericin were identified. The constituents of the extracts were quantified using HPLC-DAD (high-performance liquid chromatography-diode array detector). Isolation of the compounds from n-BuOH and EtOAc extracts was conducted by column chromatography. Antioxidant capacity of the extracts was evaluated by superoxide radical and ABTS root+ scavenging assays and inhibition of lipid peroxidation. The EtOAc extract of H. richeri was the most potent antioxidant in all experiments. Free radical scavenging compounds were identified by HPLC-DPPH root (high-performance liquid chromatography-2,2-diphenyl-1-picrylhydrazyl) post-column derivatisation method, where all phenolic compounds except I3,II8-biapigenin exhibited radical scavenging properties. This is the first report of the presence of myricetin-3-O-rutinoside, myricetin-3-O-galactoside, myricetin-3-O-glucoside, 5-O-caffeoylquinic acid and I3,II8-biapigenin in H. richeri.
