Oplopanax elatus(Nakai) Nakai, a member of the ancient angiosperm plant family Araliaceae, is used for the treatment of different disorders in the medicine systems of China, Russia, and Korea, and was designated in Russia as a classical adaptogen. Despite extensive studies of classical adaptogens, there are comparatively few reports concerning the chemical composition and pharmacological effects of O. elatus in English. The plant is a potential source of saponins, flavonoids, anthraquinones, terpenes, and other active compounds. Experimental studies and clinical applications have indicated that O. elatus possesses a number of pharmacological activities, including adaptogenic, anti-convulsant, anti-diabetic, anti-fungal, anti-inflammatory, anti-oxidant, blood pressure modulating, and reproductive function effects. In this review, the chemistry, safety, and therapeutic potential of O. elatus are summarized and highlighted to encourage the further development of this plant.  相似文献

OBJECTIVE: To investigate the effects of Zhuyesh- igao granule (ZSG) on tumor necrosis factor-a (TNF-a), interleukin-1 (IL-1), IL-2, IL-6, and IL-8 in rats with radiation esophagitis. METHODS: Fifty Wistar rats were randomly divid- ed into five groups (10 rats in each group): con- trol (without radiation), saline-treated, and low, medium, and high-dose ISG-treated groups. Rats were given normal saline (10 mL/kg) or 1.15, 2.3, or 4.6 g/kg ZSG by intragastric administration once a day for 7 days. A rat model of radiation esophagi- tis was established by local irradiation of Co60 (490.25 cGy/min, totaling 30 Gy). The administra- tion of ZSG was continued for another 7 days and on the 7th day post-irradiation, inferior vena cavablood was collected. The serum was separated, and TNF-a, IL-1, IL-2, 11_-6, and IL-8 protein levels were determined. RESULTS: Inflammatory response factors were found in the serum of each group. However, levels in ZSG-treated groups were significantly lower than in the saline-treated group (P〈0.05). CONCLUSION: ZSG may prevent the development of radiation esophagitis, perhaps by inhibiting the generation and release of the inflammatory re- sponse factors TNF-a, IL-1, IL-2, IL-6, and IL-8.  相似文献

Some plants have proven efficacy in the management of diabetes mellitus, of which Costus afer is one. This study was designed to evaluate the cytological and biochemical properties, and comparative ameliorating effects, of an aqueous extract of Costus afer Ker Gawl.(Costaceae) leaf and glibenclamide(GBM), in liver, kidney, and pancreatic injury induced by alloxan. Thirty male albino rats were divided into six weight-matched groups. Group one served as the negative control(non-induced and non-treated, control), while groups 2–6 were alloxan-induced diabetic groups. Group 2 served as a positive control(induced and non-treated, IC), groups 3–5 were treated with different doses of the extract(375, 750, and 1 125 mg/kg body weight) and glibenclamide, respectively. Body weight, absolute and relative organ weights, food and fluid intake, levels of serum glucose and liver enzymes and kidney parameters were calculated and compared. Hepatocytes, renal tubules, and pancreatic cells of diabetic rats, in diabetic non-treated and treated rats were harvested and examined histopathologically. There was dose dependent amelioration on the injuries induced by alloxan on both hepatocytes, renal tubules, and pancreatic cells after treatment with Costus afer. The glucose level was reduced significantly in the Costus afer treated diabetic rats compared with the non-treated diabetic group. Costus afer leaves seem to be effective against diabetic cell injury induced in rat liver, kidney, and pancreas.  相似文献

OBJECTIVE: Few studies have investigated the ef- fects produced by combinations of polysaccharides and chemotherapeutic drugs in cancer treatment. We hypothesized that a combination of polysaccha- rides (COP) from Lentinus edodes and Tricholoma matsutake would improve the efficacy of 5-fluoro- uracil (5-FU)-mediated inhibition of H22 cell growth. METHODS: Mice were injected H22 cells and then treated with either 5-FU, polysaccharides from Tri- choloma matsutake (PTM), polysaccharides from Lentinus edodes (PL), PTM + PL, 5-FU + PTM, 5-FU + PL, or 5-FU + COR The tumor weight and volume, and splenic CD4 + and CD8 + T cell frequencies, were determined. Additionally, splenic natural killer (NK) cell and cytotoxic T lymphocyte (CTL) activities were assessed and the serum levels of tumor necro- sis factor-a (TNF-a), Interleukin-2 (IL-2), and Interfer- on-y (IFN-y) were measured. RESULTS: Compared with mice from the control,5-FU, PL, PTM, PTM + PL, 5-FU + PL, and 5-FU + PTM groups, mice treated with 5-FU + COP showed: (a) significantly reduced tumor weight and volume (P〈 0.05), (b) significantly higher serum levels of TNF-α, IL-2, and IFN-y (P〈0.05), (c) significantly increased CD4+ and CD8+ 1 cell frequencies in the spleen (P〈 0.05), and (d) significantly increased splenic NK cell and CTL activities (P〈0.05). The tumor weight and volume in mice treated with 5-FU+PL or 5-FU+PTM were significantly reduced compared with mice treated with 5-FU alone (P〈0.05). Serum levels of TNF-α, 11.-2, and IFN-y, frequencies of CD4 + and CD8+ T cells in the spleen, and splenic NK and CTL activities were also significantly increased in mice treated with 5-FU+PL or 5-FU+PTM compared with mice treated with 5-FU alone (P〈0.05). CONCLUSION: Polysaccharides from Lentinus edodes and Tricholoma matsutake could enhance the efficacy of 5-FU-mediated H22 cell growth inhi- bition.  相似文献

Perilla frutescens(Perilla leaf), a garnishing vegetable in East Asian countries, as well as a plant-based medicine, has been used for centuries to treat various conditions, including depression. Several studies have demonstrated that the essential oil of P. frutescens(EOPF) attenuated the depressive-like behavior in mice. The present study was designed to test the anti-depressant effects of EOPF and the possible mechanisms in an chronic, unpredictable, mild stress(CUMS)-induced mouse model. With the exposure to stressor once daily for five consecutive weeks, EOPF(3, 6, and 9 mg·kg-1) and a positive control drug fluoxetine(20 mg·kg-1) were administered through gastric intubation to mice once daily for three consecutive weeks from the 3rd week. Open-field test, sucrose consumption test, tail suspension test(TST), and forced swimming test(FST) were used to evaluate the behavioral activity. The contents of 5-hydroxytryptamine(5-HT) and its metabolite, 5-hydroxyindoleacetic acid(5-HIAA), in mouse hippocampus were determined by HPLC–ECD. Serum interleukin(IL)-1, IL-6, and tumor necrosis factor(TNF)-α levels were evaluated by enzyme-linked immunosorbent assay(ELISA). The results showed that CUMS significantly decreased the levels of 5-HT and 5-HIAA in the hippocampus, with an increase in plasma IL-6, IL-1β, and TNF-α levels. CUMS also reduced open-field activity, sucrose consumption, as well as increased immobility duration in FST and TST. EOPF administration could effectively reverse the alterations in the concentrations of 5-HT and 5-HIAA; reduce the IL-6, IL-1β, and TNF-α levels. Moreover, EOPF could effectively reverse alterations in immobility duration, sucrose consumption, and open-field activity. However, the effect was not dose-dependent. In conclusion, EOPF administration exhibited significant antidepressant-like effects in mice with CUMS-induced depression. The antidepressant activity of EOPF might be related to the relation between alteration of seroto  相似文献

Mang needle (elongated needle, 芒针) is evolved from the long needle, one kind of nine needles in the ancient times, and is primarily characterized by its long needle-body and its arrival at the deep tissues of the body. However, because of the particularity of the physiology and anatomy of some diseases, direct deep puncturing can't reach the due tissues, thus the treatment results are affected. Based upon the deep puncturing of Mang needle and the physiology and anatomy of the human body, professor YANG Zhao-gang, a well-known acupuncturist, has made many improvements and innovations, in his long-term clinical practice, in the manipulations and indications of Mang needle, consequently to establish a series of unique puncturing techniques of Mang needle, which work excellently on some difficult and complicated diseases. This Mang needle therapy is introduced as follows.  相似文献

OBJECTIVE: To investigate the correlativity between the changes of blood measures related to blood stasis blocking collaterals and gene expression levels of angiotensin-converting enzyme(ACE)and ACE2 ofrenal cortex in diabetic rats with stasis blocking collaterals syndrome, as well as the effectof stasis removing and collaterals dredging.METHODS: Male Sprague-Dawley rats were divided randomly into normal control group(C group),high-carbohydrate-fat control group(H group) and streptozotocin(STZ)-injecting group. The diabeticrats were induced from rats in the STZ-injecting groupby high-carbohydrate-fat diet combined with STZ intraperitoneal injection, with sustained high-carbohydrate-fat diet fed afterwards, and were further divided into model group(M group)and Chinese medicine of stasis removing and collaterals dredging group(Z group). Rats in the Z group were fed with stasis-removing-and-collaterals-dredging herbal granule suspension intragastrically daily for 16 weeks, while drinking water of corresponding volume was administrated to the rats in other groups. At the end of the 16 th week after successful establishment of models, the ultrastructures of glomeruli in different groups were detected by a transmission electron microscopy; and blood measures related to blood stasis blocking collaterals, including lipid profile and blood viscosity measures, were tested, as well as the relative gene expressions of ACE and ACE2.RESULTS: Changes in ultrastructures of glomeruli in the M group were characterized by lack of clarity in structure and occasional thickening of glomerular basement membrane and extensive fusion in foot processes. The correlation analysis showed that there were positive correlations between lipid profile, blood viscosity, and the ACE mRNA expression levels in the M group(P〈0.05), except for cholesterol. And except for triglyceride, the blood measures were in negative correlation with the ACE2 mRNA expression levels in the M group(P〈0.05).Compared with the C  相似文献

OBJECTIVE: To explore the relationship between Renying pulse (carotid) augmentation index (AI) and Cunkou pulse condition in different blood pres- sure groups, and the clinical significance of Reny- ing and Cunkou pulse parameters to reflect vascu- lar function. METHODS: Eighty-six patients with essential hyper- tension (EH) and 52 individuals with normal blood pressure (control group) between and January 2012 were included September 2010 this study. Reny- ing pulse AI was examined by a new diagnostic tool (ALOKA ProSound Alpha 10) --wave intensity (Wl) that is calculated as the product of the deriva- tives of the simultaneously recorded blood pres- sure changes (dP/dt) and blood-flow-velocity changes (dU/dt), while Cunkou pulse condition was detected by DDMX-100 Pulse Apparatus inboth EH and control groups. A multifactorial corre- lation analysis was performed for data analysis. RESULTS: After adjusting for potential confound- ing variables, in the EH group, AI was positively cor- related with ts, w2/t (rts=0.225, P〈0.05; rw2/t=0.230, P〈 0.05) and negatively correlated with hs, hs/hl and w2 (rhs=- 0.393,P〈0.01 ;rhs/l=- 0.444, P〈0.01 ;rw2=- 0.389, P〈0.01). In the control group, AI was positively cor- related with t3, t4, ts and w, (rt3=0.595, P〈0.01; r,4= 0.292, P〈0.05; rt5=0.318, P〈0.05; rw1=0.541, P〈0.01) and negatively correlated with h1, h2, h3, Ad and A (rh1= - 0.368, P〈0.05; rh2= - 0.330, P〈0.05; rh3= - 0.327, P〈 0.05; rAd=- 0.322, P〈0.05; rA=- 0.410, P〈0.01). In the total sample group (EH plus control group, n= 138), AI was positively correlated with t, ts, w1 and w, (rt=0.257, P〈0.01; rt5=0.266, P〈0.01; rw1=0.184, P〈 0.05; rw/t=0.210, P〈0.05) and negatively correlated with hs, hs/hl, w2 and Ad (rhs= - 0.230, P〈0.01; rh5/h1= - 0.218, P〈0.05; rw2= - 0.267, P〈0.01; rAd= - 0.246, P〈0.01).

OBJECTIVE: To collect preliminary data on the effects of Saam acupuncture with regard to the immunity in cancer patients.METHODS: Ten cancer patients were analyzed for improvements in immunity. Acupuncture was applied at the 5 acupuncture points, Jingqu(LU 8), Zutonggu(BL 66), Yanggu(SI 5), Yangchi(TE 4), and Zhongwan(CV 12) for 2 weeks with 4 sessions. We assessed the effect of Korean Saam acupuncture on the immune system in cancer patients by measuring particular blood cell subsets, including CD3 +,CD4+, CD8+, CD19+, and CD56+ cells, as well as total white blood cell count, absolute neutrophil count, and fatigue score. The measurement was performed before and after acupuncture and at a 2-week follow-up.RESULTS: There was a statistically significant increase in the number of CD3+(P=0.023) and CD8+ cells(P〈0.001) and T-cell subsets, as well as a decrease in the fatigue severity scale(FSS) score(P=0.001) after Saam acupuncture using the 5 acupoints.CONCLUSION: Acupuncture may improve the immune system by increasing the counts of a few immune cells and relieve fatigue in cancer patients by decreasing FSS scores. Although this was a non-controlled study, it constitutes preliminary research investigating the potential effects of Saam acupuncture in increasing the counts of several immune cells in cancer patients.  相似文献

OBJECTIVE: To explore the anticancer mechanism of aqueous extract of Taxus Chinensis (Pilger) Rehd (AETC). METHODS: The serum pharmacological method was used to avoid interference from administration of the crude medicinal herbs. Eight purebred NewZealand rabbits were used for preparation of serum containing various concentrations of AETC. For- ty-eight Balb/c-nu mice were used for in vivo experi- ments. The effects of serum containing AETC on the proliferation of A549 cells and expression levels of the epidermal growth factor receptor/mito- gen-activated protein kinase (EGFR/MAPK) path- way-related proteins in vitro were investigated. Ad- ditionally, the effects on the growth of A549 xeno- grafts in nude mice, and expression levels of the EG- FR/MAPK pathway-related proteins in the xeno- grafts, were investigated. RESULTS: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl- tetrazolium bromide (MTT) assay revealed that the serum containing AETC significantly decreased the viability of A549 cells in a dose-dependent manner. Western blot showed that the serum containing various concentrations of AETC strongly reduced the levels of phospho-Jun N-terminal kinase (p-JNK) and phospho-extracellular signal-regulated kinasel/2 (ERK1/2) while it increased the level of p-p38. However, no significant effects on the ex- pression levels of JNK, ERK1/2, and p38 MAPK were found. In addition, an anticancer effect from AETC was observed in vivo in the Balb/c-nu mice bearing A549 xenografts.CONCLUSION: AETC has significant effects on the growth of A549 xenografts and on the activity of the EGFR/MAPK pathway. Therefore, AETC may be beneficial in lung carcinoma treatment.  相似文献

OBJECTIVE: To assess the effects of using Chinese herbs in assisted reproductive technology. METHODS: Four hundred and thirty-three subjects aged less than 42 years with infertility due to Fallo- pian tube or male-related factors who were willing to undertake in vitro fertilization and embryo trans- plantation were randomly allocated to a Chinese herb intervention group (n=216) or a conventional treatment control group (n=217). All subjects re- ceived one of four routine ultra-ovulation-promot- ing therapies at the Reproductive Center in the Third Hospital Affiliated to Beijing University ac- cording to their physician's assessments. The sub- jects in the intervention group received various Chi- nese herbs depending on their conventional treat- ment. Endometrial thickness, number of acquired eggs, and rates of normal fertility, high-quality em- bryos, biochemical and clinical pregnancy of sub- jects were assessed in both groups.RESULTS: The high-quality embryo rate of 51.9%, biochemical pregnancy rate of 51.0%, clinical preg- nancy rate of 44.2% and endometrial thickness of (10.84± 1.75) mm in the intervention group were all significantly higher than those in the control group [48.7%, 38.9%, 34.8%, and (10.52±1.50) mm, respec- tively; P〈O.05]. The normal fertility rate of 58.5% in the Chinese herb group was also significantly supe- rior to the 54.7% achieved in the control group (P〈 0.01). There were no statistically significant differ- ences (P〉0.05) in the average number of acquired eggs within a single cycle, incidence of excessive stimulation of ovary, rates of embryo transplanta- tion or early abortion and birth of living babies be- tween the two groups. CONCLUSION: Our findings indicate that Chinese herbs increase endometrial thickness, improve the quality of fertility and embryo, and promote embry- onic nidation, thus enhancing the success rate of in vitro fertilization/intracytoplasmic sperm injec- tion-embryo transplantation cycle.

To improve the function of endothelial progenitor cells (EPCs) is one of the goals in Chinese traditional therapy to treat various cardio-celebrovascular diseases. In the past decades, scholars in the field of traditional Chinese medicine (TCM) have found fifteen active compounds to regulate the function of EPC. These metabolites are extracted from thirteen, plant-based Chinese medicine, with majority of them as potent reductive or oxidative hydrophilic molecules containing phenyl groups. These active compounds either enhance the mobilization of EPC, or inhibit their apoptosis through different signaling pathways. In this review, the molecular structure, biophysical properties, and the plant sources of these active ingredients and their regulatory effects on the function of EPC are summarized, aiming to reveal the modem basis of Chinese medicine for promoting blood circulation and removing blood stasis at the progenitor cell level.  相似文献

OBJECTIVE: To study changes in the nuclear factor-κB p65(NF-κB p65)-inducible nitric oxide synthase(i NOS)-nitric oxide(NO) signaling pathway and the effects of Xinfeng capsules(XFC) in patients with ankylosing spondylitis(AS)METHODS: One hundred twenty patients with AS were randomly divided into an XFC group and a Salazopyrin group. Sixty health subjects were included as a normal control group. In the two treatment groups, pulmonary functional parameters,forced vital capacity(FVC), forced expiratory volume in 1 second(FEV1), maximal voluntary ventilation(MVV), peak expiratory flow(PEF), forced expiratory flow at 25% of forced vital capacity(FEF25),forced expiratory flow at 50% of forced vital capacity(FEF50), and forced expiratory flow at 75% of forced vital capacity(FEF75) were determined. Enzyme linked immunosorbent assays were used for detection of the serum oxidative stress indexes,NF-κB p65, i NOS, NO, reactive oxygen species(ROS), reactive nitrogen species(RNS), malondialdehyde(MDA), superoxide dismutase(SOD), catalase(CAT), total antioxidative capacity(TAOC) and interleukin-4(IL-4), IL-10, IL-1β, and tumor necrosis factor-α(TNF-α) contents. Westergren's method was used for determination of erythrocyte sedimentation rate(ESR). High-sensitivity C-reactive protein(Hs-CRP) was detected with a 7060 full-automatic biochemical analyzer(Hitachi, Japan).RESULTS: The clinical therapeutic effect in the XFC group was significantly superior to that in the Salazopyrin group(P〈0.01). Compared with the normal control group, FEV1, MVV, PEF, FEF50, FEF75, SOD, CAT,TAOC, IL-4, IL-10 were significantly lower, and NF-κB p65, i NOS, NO, ROS, RNS, MDA, IL-1β, TNF-α, ESR,and Hs-CRP significantly higher in patients with AS(P〈0.01 or P〈0.05). Compared with before treatment, FEV1, MVV, PEF, FEF50, FEF75, SOD, CAT, TAOC,IL-4, and IL-10 were significantly increased, and NF-κB p65, i NOS, NO, ROS, RNS, MDA, IL-1?  相似文献
