Comparative authentication of Semiliquidambar cathayensis and its substituted species via macroscopic and microscopic features / 中草药·英文版

Objective: Ban Fenghe recorded in the Quality Standard of Yao Medicine of Guangxi Zhuang Autonomous Region (Volume 1) is derived from the dried stems and leaves of Semiliquidambar cathayensis. It is usually confused with medicinal herbs from Pterospermum heterophyllum and Dendropanax dentiger. However, they are very different in chemical composition, and should not be used as the same drug. To ensure their safety and efficacy, a method based on macroscopic and microscopic characteristics was developed to distinguish them. Methods: A total of 14 batches of Ban Fenghe samples from three species were collected from different producing areas in China. The macroscopic characteristics were examined by observing external traits. The tissue structures of transverse sections of stems and leaves, the leaf epidermis, and the powder were observed microscopically. Results: The branchlets and leaf surfaces of S. cathayensis and P. heterophyllum were hairy, especially the lower leaf surfaces of P. heterophyllum were densely covered with hairs, but those of D. dentiger were hairless. The pericyclic fibers of S. cathayensis stems were intermittently distributed in a circular shape and accompanied by stone cells, whereas those of P. heterophyllum and D. dentiger were bundled without stone cells. So stone cells and hairs were present in S. cathayensis powder, stone cells were not found in P. heterophyllum and D. dentiger powder, and hairs were not present in D. dentiger powder. The distribution sites, sizes and types of secretory tissues of these three species were also different in transverse sections of stems and leaves. Stomata on the lower epidermis of S. cathayensis leaves were paracytic, whereas those of P. heterophyllum and D. dentiger were anomocytic. Conclusion: Ban Fenghe drugs derived from S. cathayensis could readily be distinguished from those of P. heterophyllum and D. dentiger by macroscopic and microscopic features.

<p><b>OBJECTIVE</b>To investigate the neuro-protective effects of Acanthopanax senticosus Harms (EAS) on mesencephalic mitochondria and the mechanism of action, using a mouse model of Parkinson's disease (PD).</p><p><b>METHODS</b>The chemical fingerprint analysis of the extract of Acanthopanax senticosus Harms (EAS) was performed using the ultra performance liquid chromatograph and time of flight mass spectrometry. Thirty mice were randomly divided into the control group, the MPTP model group, and the EAS treated group with MPTP (MPTP+EAS group, 10 in each group). The MPTP model group and the MPTP+EAS group received MPTP-HCl (30 mg/kg i.p) once a day for 5 days. The control group received an equal volume of saline (20 mL/kg i.p) once a day for 5 days. Induced by 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine hydrochloride daily (MPTP-HCl, 30 mg/kg) for 5 days, the PD mice were treated with EAS at 45.5 mg/kg daily for 20 days. The behavioral testing of mice was carried out using the pole-climbing test. The integrity and functions of neurons were examined in mesencephalic mitochondria in a PD mouse model, including nicotinamide adenine dinucleotide dehydrogenase ubiquinone flavoprotein 2 (NDUFV2), mitochondrially encoded nicotinamide adenine dinucleotide dehydrogenase 1 (MT-ND1), succinate dehydrogenase complex subunit A (SDHA), and succinate dehydrogenase cytochrome b560 subunit (SDHC).</p><p><b>RESULTS</b>After treatment with EAS, the behavioral changes induced by MPTP were attenuated significantly (P<0.05). EAS protected the mesencephalic mitochondria from swelling and attenuated the decreases in their membrane potential (both P<0.05), which was supported by an ultra-structural level analysis. The changes in reactive oxygen species (ROS), malonic dialdehyde (MDA), oxidative phosphorylation (OXPHOS) system 4 subunits levels and PD-related proteins expressions (parkin, Pink1, DJ-1, α-synuclein, and Lrrk2) reverted to near normal levels (all P<0.05), based on the results of immune-histological and Western blotting observations.</p><p><b>CONCLUSIONS</b>The neuro-protective effects of EAS are linked to protecting mice against MPTP-induced mitochondrial dysfunction and structural damage. Therefore, EAS is a promising candidate for the prevention or treatment of mitochondrial neurodegenerative disorders, such as PD.</p>

Food and Drug Interactions: Effect of <i>Acanthopanax senticosus</i> Harms on CYP3A4 and CYP2C9 Activities (Part 3) / 日本補完代替医療学会誌

<b>Objective:</b> By using human liver microsomes (HLM), we analyzed the effects of 14 known components of <i>A.senticosus</i> Harms on the activities of CYP2C9 and CYP3A4.<br> <b>Methods and Results:</b> Sesamin and quercetin inhibited both enzyme activities, whereas quercitrin strongly inhibited CYP3A4 activity. The 50% inhibitory concentrations (IC₅₀s) of sesamin and quercetin on CYP2C9 activity were approximately 124- and 59-fold higher and the IC₅₀s of sesamin, quercetin, and quercitrin on CYP3A4 activity were approximately 427-, 135-, and 22-fold higher than that of <i>A. senticosus</i> Harms extract (ASE), respectively. All these components inhibited both CYP3A4 and CYP2C9 in a non-competitive manner. However, these components are present in small amounts in ASE.<br> <b>Conclusion:</b> Therefore, the food-drug interactions caused by <i>A. senticosus </i>Harms are presumed to be due to the additive or synergistic interaction of these components or the other existing components, including their metabolites.<br>

Food and Drug Interactions: Effect of <i>Acanthopanax senticosus</i> Harms on CYP2C9 Activity (Part 2) / 日本補完代替医療学会誌

<b>Objective:</b> <i>Acanthopanax senticosus</i> Harms extract (ASE) is an ingredient of functional foods, such as health supplements, in Japan. We investigated the effects of ASE on CYP2C9 activity.<br> <b>Methods and Results:</b> CYP2C9-catalyzed diclofenac 4′-hydroxylase activities in human intestinal and liver microsomes (abbreviated as HIM and HLM, respectively) were significantly decreased by the addition of ASE in a concentration-dependent manner. Kinetic studies of diclofenac 4′-hydroxylase in HLM revealed that ASE addition significantly decreased <i>V</i>_max but had no effect on <i>K</i>_m. These results suggest that diclofenac 4′-hydroxylase activity is suppressed by ASE addition in a non-competitive manner. Then, we investigated the time courses of diclofenac 4′-hydroxylase activity in rat liver microsomes after ASE oral administration (50 to 400 mg/kg). Diclofenac 4′-hydroxylase activities were significantly lowered by the administration of 200 and 400 mg/kg ASE at 0.5 to 4 hr compared with control (0 hr). Furthermore, we investigated the effects of ASE oral administration on the pharmacokinetics of tolbutamide (substrate for CYP2C9) in rats. The area under the concentration-time curve of tolbutamide after ASE oral administration (400 mg/kg) was enhanced by approximately 1.6 times compared with that without ASE oral administration.<br> <b>Conclusion:</b> These findings indicated that ASE inhibits human intestinal and hepatic CYP2C9 activities.<br>

A Comparative Study of the Anterior Cervical Fusion with Harms Cage versus Iliac Bone Block: Clinical and Radiological Outcomes

STUDY DESIGN: A retrospective study. OBJECTIVES: To evaluate the clinical and radiological outcomes of anterior cervical fusion within Harms cage versus an iliac bone block graft. SUMMARY OF LITERATURE REVIEW: There is no current consensus regarding the optimal material for anterior cervical fusion. MATERIALS AND METHODS: This was a single-center study of 107 patients who either underwent anterior cervical fusion with an iliac bone block graft (n=56; group A) or a cancellous bone graft within the cervical Harms titanium cage (n=51; group B). Anterior plating occurred in all cases. Clinical outcomes and complications were evaluated using Visual Analogue Scale (VAS) scores and Odom's Criteria. Radiological outcomes were evaluated by the height of vertebral bodies, sagittal lordosis, the rate of bony union, and the subsidence of cage. RESULTS: The VAS of donor site pain was significantly higher in group A than in group B at the final follow-up. Sagittal lordosis was increased in both groups, but was significantly higher in group B than group A. The rate of bony union was 95% and 91% for both groups 6 months after surgery and reached 100% for both groups at the final follow-up. In terms of cage subsidence, the highest point of subsidence was at the inferior and posterior aspect of the cage and the average amount of subsidence was approximately 1.3 mm at final follow-up. CONCLUSIONS: Anterior cervical fusion using a cancellous bone graft within Harms titanium cage is a good method for anterior cervical fusion with iliac bone block.
