ABSTRACT

Network pharmacology and the mouse model of viral pneumonia caused by influenza virus FM_1 were employed to explore the main active components and the mechanism of Pulsatilla chinensis against the inflammatory injury of influenza virus-induced pneumonia. The components and targets of P. chinensis were searched from TCMSP, and the targets associated with influenza virus-induced pneumonia were searched from GeneCards. The common targets between P. chinensis and influenza virus-induced pneumonia were identified with Venn diagram established in Venny 2.1. The herb-component-disease-target(H-C-D-T) network was constructed by Cytoscape 3.7.2. The above data were imported into STRING for PPI network analysis. Gene Ontology(GO) enrichment and KEGG pathway enrichment were performed with DAVID. BALB/cAnN mice were infected with the influenza virus FM_1 by nasal drip to gene-rate the mouse model of pneumonia. Immunohistochemistry was adopted to the expression profiling of inflammatory cytokines in the lung tissues of mice in the blank group, model group, and P. chinensis group 1, 3, 5, and 7 days after infection. The pathological changes of lung and trachea of mice in blank group, model group, and P. chinensis group were observed with light microscope and scanning electron microscope at all the time points. The network pharmacological analysis indicated that 9 compounds of P. chinensis were screened out, with a total of 57 targets, 22 of which were overlapped with those of influenza virus-induced pneumonia. A total of 112 GO terms(P<0.05) were enriched, including 81 terms of biological processes, 11 terms of cell components, and 20 terms of molecular functions. A total of 53 KEGG signaling pathways(P<0.05) were enriched, including TNF signaling pathway, influenza A signaling pathway, NF-κB signaling pathway, MAPK signaling pathway and other signaling pathways related to influenza/inflammation. In the P. chinensis group, the expression of TNF-α and IL-1 in the lung tissue was down-regulated on the 3 rd day after infection, and that of IL-6 in the lung tissue was down-regulated on the 5 th day after infection. Light microscopy and scanning electron microscopy showed that P. chinensis significantly alleviated the pathological damage of lung and trachea compared with the model group. This study reflects the multi-components, multi-targets, and multi-pathways of P. chinensis against influenza virus-induced pneumonia. P. chinensis may reduce the production of proinflammatory cytokines and mediators and block the pro-inflammatory signaling pathways to alleviate viral pneumonia, which provides reference for future research.

ABSTRACT

BACKGROUND: Oral cancer is one of the common malignant tumors of the head and neck. However, current treatments have numerous side effects, and drugs from natural sources may have better therapeutic potential. This research investigated the induction of apoptosis by α-hederin (α-HN), a constituent of Pulsatilla chinensis (Bunge) Regel, in the oral cancer cell line SCC-25 and its underlying mechanism. RESULTS: SCC-25 cells were treated with 50, 100, and 200 µmol/L α-HN. Cell proliferation; extent of apoptosis; activities of caspases-3, 8, and 9; and the expression of Bcl-2, Bax, phosphorylated (p)-phosphoinositide 3-kinase (PI3K), p-Akt, and p-mammalian target of rapamycin (mTOR) proteins were determined using the 3-(4,5)-2-thiazole-(2,5)-diphenyl tetrazolium bromide, flow cytometry, caspase activity detection kits, and western blot assays, respectively. The results showed that the proliferation of SCC-25 cells in the α-HN-treated groups decreased significantly, and the inhibitory effect was time and concentration dependent. Compared with cells in the control group, the extent of apoptosis increased significantly, caspase-3 and -9 activities were significantly enhanced, and the Bcl-2 level was lowered and the Bax level was elevated significantly in SCC-25 cells treated with α-HN for 48 h (P b 0.05). The expression of p-PI3K, p-Akt, and p-mTOR was also significantly lower in SCC-25 cells treated with α-HN than that in the control group (P b 0.05). CONCLUSION: These results indicate that α-HN can inhibit proliferation and induce apoptosis of SCC-25 cells and may exert these effects by inhibiting the PI3K/Akt/mTOR signaling pathway.

ABSTRACT

Extraction and fractionation of Pulsatilla koreana flowers followed by, repeated open column chromatography for EtOAc and n-BuOH fractions yielded four flavonoid glycosides, namely, astragalin (1), tiliroside (2), buddlenoide A (3), and apigenin-7-O-(3"-E-p-coumaroyl)-glucopyranoside (4). The chemical structures of these flavonoid glycosides were elucidated on the basis of various spectroscopic methods including electronic ionization mass spectrometry (EI-MS), 1D NMR (1H, 13C, DEPT), 2D NMR (gCOSY, gHSQC, gHMBC), and infrared (IR) spectrometry. This study represents the first report of the isolation of the flavonoid glycosides from the flowers of P. koreana.

ABSTRACT

OBJECTIVE@#To explore the eff ect of pulchinenoside (PULC) on fi broblast-like synoviocytes (FLS) apoptosis in adjuvant arthritis (AA) rats.@*METHODS@#A total of 60 SD rats were randomly divided into 8 groups: A normal control group, an AA group, a low PULC group (50 mg/kg), a middle PULC group (100 mg/kg) or a high PULC group (150 mg/kg) and an ibuprofen (8 mg/kg) group (n=10 per group). FLS from the AA rats was cultured. The expression of Bcl-2, Bax, caspase-3 and the FLS proliferation were detected by the real time qPCR and MTT, respectively. The expression of IL-6 and IL-8 in culture medium was detected by ELISA.@*RESULTS@#Compared with the AA group, the Bcl-2 expression was down-regulated (all P<0.05), the Bax and caspase-3 expression was up-regulated (all P<0.05), and the FLS proliferation was inhibited (all P<0.05). The IL-6 and IL-8 expression was suppressed in the FLS in the PULC groups at different dosages (all P<0.05) as well as in the ibuprofen group (P<0.05).@*CONCLUSION@#PULC may inhibit the FLS proliferation in AA rats by increase in FLS apoptosis.

ABSTRACT

HPLC-ELSD was applied to explore the absorption mechanism of pulchinenosides (B3, BD, B7, B10, B11) in rats. The experimental results showed that the absorption rate constant, Ka value (B3, BD) and Permeability coefficient, Peff value (B3, B7) displayed significant difference (P <0.05) in various intestinal segments, The Ka value and Peff value of PRS was different from each other with the highest absorption in duodenum (duodenum > jejunum > colon > ileum); The PRS displayed excessive satuation as the concentration increased over 0.05-2.5 g · L(-1). There were no obvious linear correlations between Peff values and concentrations in duodenum (0.6007 ≤ R2 ≤ 0.7727); Ka and Peff value declined when the PRS was perfused with P-glycoprotein promoter digoxin, on the other hand, inclined when perfused with P-glycoprotein inhibitor verapamil with significant difference among PRS B3, BD, B7, B11 (P <0.05). All the above results demonstrated that B3, BD, B7 were greatly influenced by absorption sites, duodenum was the main absorption site; PRS didn't entirely transported in a concentration dependent manner, and the transporter-protein involved the transportation, so the intestinal absorption of the five pulchinenosides was not entirely passive diffusion; and PRS might be the substrates of P-glycoprotein.

ABSTRACT

In this study, 23 oleanane-type triterpenoid saponins were isolated from a methanol extract of the roots of Pulsatilla koreana. The NF-kappaB inhibitory activity of the isolated compounds was measured in TNFalpha-treated HepG2 cells using a luciferase reporter system. Compounds 19-23 inhibited TNFalpha-stimulated NF-kappaB activation in a dose-dependent manner, with IC50 values ranging from 0.75-8.30 microM. Compounds 19 and 20 also inhibited the TNFalpha-induced expression of iNOS and ICAM-1 mRNA. Moreover, effect of the isolated compounds on PPARs transcriptional activity was assessed. Compounds 7-11 and 19-23 activated PPARs the transcriptional activity significantly in a dose-dependent manner, with EC50 values ranging from 0.9-10.8 microM. These results suggest the presence of potent anti-inflammatory components in P. koreana, and will facilitate the development of novel anti-inflammatory agents.

ABSTRACT

Um dos insumos mais utilizados na manufatura de medicamentos homeopáticos é a tintura-mãe. Um método aparentemente útil para o controle de qualidade das tinturas-mães é a análise capilar. Este método analítico, tornado público no início do século passado por Hugo Platz, caiu em desuso após o advento de técnicas cromatográficas mais modernas. Embora empregue técnicas simples e de baixo custo, não há estudos de validação da análise capilar. O presente ensaio teve por objetivo validar o método de análise capilar utilizado no controle de qualidade de tinturas-mãe. Para tanto foram obtidos os espectros capilares das tinturas-mãe de Aconitum napellus L., Strychnos nux vomica L. e Anemone pulsatilla L. provenientes de fornecedores nacionais qualificados pela Associação Brasileira de Farmacêuticos Homeopatas. Os atributos avaliados foram precisão, reprodutibilidade e seletividade. Os resultados alcançados recomendam a utilização do método de análise capilar, conforme proposto por Platz, nas análises qualitativas de tinturas-mãe.


Mother tinctures are one of the most common starting materials used in the elaboration of homeopathic medicines. Capillary analysis seems a useful method for quality control of mother tinctures. This method was publicized in the beginning of the 20th century by Hugo Platz to fell into disuse following the development of the modern chromatographic techniques. Despite the simple techniques involved, and the low cost of the overall method, no studies of validation have yet been performed of Platz´s capillary analysis. The present study sought to validate capillary analysis for quality control of mother tinctures. The capillary spectra of mother tinctures of Aconitum napellus L., Strychos nux vomica L. e Anemone pulsatilla L. provided by Brazilian suppliers certified by the Brazilian Association of Homeopathic Pharmacists were obtained. The attributes evaluated were accuracy, reproducibility and selectivity. The results allow recommending the use of capillary analysis as formulated by Platz for qualitative analysis of mother tinctures.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the toxicity of Pulsatilla chinensis (Bunge) Regel saponins (PRS) against Oncomelania hupensis (O. hupensis).</p><p><b>METHODS</b>O. hupensis snails were exposed to 40% and 80% of 24 h LC50 of PRS for 24 h, and then choline esterase (CHE), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) activities in cephalopodium and liver of snails were determined. Niclosamide (NIC) was used as the reference molluscicide. Zebra fish lethality test was evaluated to non-target aquatic species of PRS.</p><p><b>RESULTS</b>The molluscicidal activity of PRS (LC50 at 24 h: 0.48 mg/L) was similar to that of NIC (LC50 at 24 h: 0.16 mg/L). Significant alterations about CHE, ALP, and ALT activities both in the cephalopodium and the liver of snails were observed when O. hupensis was exposed to 40% and 80% LC50 of PRS or NIC for 24 h. PRS and NIC could not affect LDH activity in the cephalopodium and the liver. Lower toxicity to fish of PRS was observed up to the highest concentration tested than NIC.</p><p><b>CONCLUSION</b>PRS, as compared with the reference molluscicide NIC, is thought to be used for the control of harmful vector snails safely.</p>

ABSTRACT

Herb or folk medicine has readily been assumed to have a little or no adverse effects because people have taken or applied it for a long time. However, such an assumption can be dangerous. Generally herb medicine has a shorter time of action both in terms of its pharmacological efficacy and toxic effects than occidental medicine because its ingredient is less potent. Therefore herb medicine does not induce adverse reactions in a short time, but the frequency of its side effects increases along with the accumulation of medicinal substances when taken for a long time. Many doctors of Oriental medicine claim that the development of skin eruption is not a side effect of herb medicine. Rather they argue that it is a result of emission of heat or toxic materials from inside the body. Sometimes the author experience patients who suffer from drug eruptions caused by herb medicine, but usually the patients have little idea what herb medicine they have taken. This article will introduce some cases of herb medicine-induced adverse effects reported in dermatology journals, written in Korean or in English. Most cases are systemic contact dermatitis caused by ingestion of chicken boiled with lacquer, which has been used as a folk medicine and a healthy food. I will introduce what the Rhus lacquer is and discuss its adverse reactions. Lastly, I will report the cases of contact dermatitis caused either by applying crushed insect and medicinal herbs such as buttercup, fig leaf, garlic, pasqueflower, aloe and herbal ointment or by practicing bee sting therapy for treatment of neuralgia, arthralgia, tinea pedis, facial paralysis, pruritus and paresthesia.
