Dill (Anethum graveolens L.) seed essential oil induces Candida albicans apoptosis in a metacaspase-dependent manner

Dill (Anethum graveolens L.) has been used in traditional Uighur medicine for its various pharmacological activities. Previous studies have suggested that dill seed essential oil (DSEO) has anti-Candida potential and the mechanism of its action also has been studied. Our study examined whether DSEO induces apoptosis in the human pathogen Candida albicans ATCC 64550. Our results indicate that C. albicans ATCC 64550 cells treated with DSEO show some typical apoptosis characters, such as decrease in adenosine triphosphatase (ATPase) activity, chromatin condensation, nuclear fragmentation, and phosphatidylserine (PS) exposure. The DSEO promoted cytochrome c (cyt c) release and metacaspase activation, which resulted in C. albicans ATCC 64550 apoptosis. l-cysteine prevented the DSEO-induced nuclear fragmentation, PS externalization, and metacaspase activation, thus indicating that the reactive oxygen species (ROS) is an important mediator of DSEO-induced apoptosis. To our knowledge, this study is the first to report the induction of apoptosis of this pathogen with concomitant metacaspase activation by DSEO.

The treatment of Uygur medicine Dracocephalum moldavica L on chronic mountain sickness rat model.

Aim:Dracocephalum moldavica L, a traditional Uygur medicine, possesses some key cardiac activities. However, till date, no reports are available on the use of D. moldavica against chronic mountain sickness (CMS), which is a medical condition that affects the residents of high altitude. The present study was designed to explore the treatment efficacy of D. moldavica on CMS.Materials and Methods:80 of the 100 Sprague Dawley rats enrolled were bred in simulated high altitude environment and the remaining 20 rats were kept in the plains. Water and alcohol extracts of D. moldavica were prepared. CMS rat model was prepared, and the rat hearts were removed for histopathological analysis. Blood samples were taken for hematological and biochemical analyses. Rat pulmonary artery pressure was determined to study the treatment efficacy.Results:In the CMS model group, the levels of interleukin-6 (IL-6), C-reactive protein (CRP), and malondialdehyde (MDA) were found to be significantly higher than the control group; while the concentrations of SOD and GSH-Px decreased. D. moldavica could improve these levels, decrease pulmonary artery pressure, and improve the cardiac pathological state.Conclusions:The study results show that IL-6, CRP, MDA, SOD and GSH-Px participate and mediate the formation of CMS and D. moldavica is found to possess noticeable effects on CMS. The present study explored the basics of high altitude sickness and laid the foundation for further progress of Uygur medicines on the treatment of altitude sickness. Further preclinical and clinical studies with more sample size are recommended.

Hepatoprotective effect of Cichorium intybus L., a traditional Uighur medicine, against carbon tetrachloride-induced hepatic fibrosis in rats.

To investigate the hepatoprotective effect of a Cichorium intybus L. extract (CIE) on CCl4-induced hepatic fibrosis in rats. Seventy-two male Wistar albino rats were randomly divided into six groups of twelve rats each. The normal control group was allowed free access to food and water. Liver injury was performed in the remaining five groups with an i.p. injection of a 1.0 mL/kg CCl4 and olive oil (2:3 v/v) mixture, twice weekly for 8 weeks. All rats, with the exception of the injury model group, were intragastrically (i.g.,) administered quantum satis (q.s.) dosages [CIE group: 6, 18, and 54 mg/kg, respectively; Fu Fang Bie Jia Ruan Gan Pian (FFBJRGP) group: 780 mg/kg]. The oral administration of different drugs was performed on the day before CCl4 administration and subsequently once per day for 8 wk. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), hexadecenoic acid (HA), laminin (LN), hydroxyproline (Hyp), and glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) in the rat livers were measured. Histopathological changes in the liver were assessed for each group using HE staining and a Masson Trichrome examination. The expression of transforming growth factor-β1 (TGF-β1) and α-smooth muscle actin (α-SMA) was examined by immunohistochemical analysis. CIE at oral doses of 6, 18, and 54 g/kg per day showed a significant hepatoprotective effect, especially at a dose of 54 g/kg per day. CIE doses reduced the levels of AST (149.04 ± 34.44, P < 0.01), ALT (100.72 ± 27.19, P < 0.01), HA (548.50 ± 65.09, P < 0.01), LN (28.69 ± 3.32, P < 0.01) and Hyp (263.33 ± 75.82, P < 0.01). With regards to hepatoprotective activity, the CIE dose of 54 g/kg per day produced the largest significant effect by increasing GSH (3.11 ± 0.81), SOD (269.98 ± 33.77, P < 0.01) and reducing MDA (2.76 ± 0.51, P < 0.01) levels in the liver. The expressions of TGF-β1 and α-SMA were measured by immunohistology and found to be significantly reduced by CIE in a dose-dependent manner. CIE may effectively protect against CCl4-induced hepatic fibrosis in rats; thus, it is a promising anti-fibrotic therapeutic agent.

Rapid discrimination of three Uighur medicine of Eremurus by FT-IR combined with 2DCOS-IR

As complicated mixture systems, traditional Chinese medicines (TCMs) are difficult to be identified and discriminated, especially for the drug samples originated from the same source. In this study, a tri-step infrared spectroscopy method, i.e., conventional infrared spectroscopy (FT-IR) combined with second derivatives spectra and two-dimensional correlation infrared spectroscopy (2DCOS-IR), was employed to study and identify three Uighur drugs of Eremurus in Xinjiang, i.e. Eremurus altaicus (Pall.) Stev (AET), E. inderiensis (M.Bieb.)Regel(CB), E. anisopterus (Kar.et Kir.) Regel(YC). It was founded that the conventional IR spectra of the three species Eremurus were very similar based on the peak positions and shapes, indicating that the three had similar chemical profiles. On the basis of the different IR spectra of reference compounds and microscopic identification, the roots of YC, CB and AET all have comparable amount of calcium oxalate. The second derivative spectra of Eremurus enhanced the spectral resolution and amplified the small differences, especially at about 1468cm−1, 1454cm−1, and 1164cm−1, and subsequently provided some dissimilarity in their calcium oxalate content. AET has relatively higher content of calcium oxalate but the lower content of anthraquinones. Moreover, the 2D-IR spectra revealed tiny differences among the three species by providing dynamic structural information of their chemical components in a more direct and visual way. The differences embodied mainly on the intensity of the auto-peaks at 971cm−1, 1008cm−1, 1468cm−1 and 1578cm−1. As a result, it was demonstrated that the macroscopic IR fingerprint method could discriminate the three similar Uighur drugs, YC, CB and AET.

Effect of Cichorium Glandulosum Extracts on CCl4-Induced Hepatic Fibrosis

Background:Cichorium glandulosum (CG), which is a Compositae family plant, is a commonly used traditional Uighur medicine capable of cleansing liver and being cholagogue, strengthening stomach, promoting digestion, inducing diuresis and reducing edema.Objectives:To study the liver and spleen indices, the levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and the histopathological changes.Materials and Methods:Rats were intragastrically administered with the extracts of a traditional Uighur medicine Cichorium glandulosum (CG). The expressions of FN, Smard3 IGFBPrPl and TGF-β1 were detected.Results:The liver and spleen indices of the CG-V group were significantly lower than those of the model group (P < 0.01). The hepatic fibrosis symptoms of the CG-V and CG-VII groups were significantly relieved, and more FN, Smard3 and IGFBPrPl were expressed than those in the normal group. The expressions of FN, Smard3 and TGF-β1 in all treatment groups were significantly higher than those in the normal group, and the expressions in the CG-V and CG-VII groups were significantly different from those in the model group (P < 0.05). Compared with the normal group, the apoptotic index of the model group was significantly higher, but the indices of the CG-V and CG-VII groups were significantly lower than that of the model group (P < 0.01).Conclusions:The extracts of CG probably exerted protective effects by influencing the TGF-β/Smads signal transduction pathway.

Association study of gene polymorphisms and depression with abnormal humor in traditional Uighur medicine

BackgroundAccording to the humor theory of Traditional Uighur Medicine (TUM), a same disease is classified into different abnormal humor types and corresponding methods are applied to treat the diseases according to the type of abnormal humor characteristics. To date the biological foundation of classification of diseases by humor theory has been little studied and the mechanism of action is still unclear. In the present study, we aimed to investigate the association between some related gene polymorphisms and depression with abnormal humor in TUM.Methods201 cases of depression patients in a Uighur population were divided into two groups as: 107 cases of depression patients with abnormal black bile (ABB), 94 cases of depression patients with none abnormal black bile (nABB), and 50 healthy people were served as control group. Venous blood was used to isolate DNA samples, and the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used for genotyping of single nucleotide polymorphisms (SNPs). Polymorphisms in the serotonin 2A (5-HT2A) receptor gene, brain derived neurotrophic factor (BDNF), serotonin 1A (5-HT1A) receptor gene were investigated in each groups, respectively.ResultsThe 5-HT2A A-1438G, 5-HT2A T102C, BDNF Val66Met, and 5-HT1A C-1019G gene polymorphisms showed significant association with ABB. However, no difference between nABB and controls was found for those genotype distribution and allele frequency. Moreover, the T102C and A1438G SNPs in the 5-HT2A receptor gene polymorphisms were in linkage disequilibrium. In addition, the OR associated with the combination of Val66Met-Val/Val genotype plus the presence of -1019C allele was 8.393 for ABB compared with controls (OR 8.393; 95% CI 1.807 ~ 38.991; P= 0.003). Moreover, the OR associated with the presence of -Met plus -1019C alleles was 12.194 for ABB compared with controls (OR 12.194; 95% CI 1.433 ~ 103.776; P= 0.005). The OR associated with the presence of -1438C/C plus Val/Val genotypes was 7.738 for ABB compared with controls (OR 7.738; 95% CI 1.566 ~ 38.241; P= 0.005).ConclusionIt was concluded that there were significant relationship between the gene polymorphisms and classification of depression with abnormal humor in TUM. The 5-HT2A A-1438G, 5-HT2A T102C, BDNF Val66Met, and 5-HT1A C-1019G gene polymorphisms might predict the incidence of depression with ABB.

Quality standard of uygur medicine Medicago sativa seeds

In this paper, microscopic identification method was adopted to observe the microscopic characters of ten batches of Medicago sativa seeds. And M. sativa seeds were identificated by TLC method in contrast to trigonelline and stachydrine hydrochloride. The impurities, moisture, ash, sour insoluble ash were detected based on Chinese Pharmacopoeia 2010 version (Vol I ). An HPLC method was also established for determination of trigonelline in the M. sativa seeds. The contents of impurities, moisture, ash, sour insoluble ash should not exceed 5%, 10%, 6%, and 2%, respectively. The content of trigonelline should be not less than 0.795 6 mg x g(-1). The experimental methods were accurate and reliable, and can be used as the quality control of the seeds of M. sativa.

Establishment and comparison of combining disease and syndrome model of asthma with "kidney yang deficiency" and "abnormal savda".

The study was the first time to establish and compare two rat models of two common syndromes: Kidney Yang Deficiency syndrome (KYDS) in traditional Chinese medicine (TCM) and abnormal savda syndrome (ASS) in traditional Uighur medicine (TUM). Then, we also established and evaluated rat models of combining disease and syndrome models of asthma with KYDS or ASS. Results showed that usage of the high dose of corticosterone (CORT) injection or external factors could successfully establish the KYDS or ASS rat models, and the two models had similar changes in biological characterization, abnormal behaviors, dysfunction of hypothalamic-pituitary-target organ axes (HPTOA), and sympathetic/parasympathetic (S/P) nerve system but varied in different degrees. The rat models of combining disease and syndrome of asthma with KYDS or ASS had either pathological characteristics of asthma such as airway hyperresponsiveness (AHR), airway inflammation, airway remodeling, which were more serious than allergy exposure alone, or the syndrome performance of Kidney Yang Deficiency in TCM and abnormal savda in TUM. These findings provide a biological rationale for further investigation of combining disease and syndrome model of asthma as an effective animal model for exploring asthma based on the theory of traditional medicine.

Behavioral, neurochemical and neuroendocrine effects of abnormal savda munziq in the chronic stress mice.

Oral administration of Abnormal Savda Munsiq (ASMq), a herbal preparation used in Traditional Uighur Medicine, was found to exert a memory-enhancing effect in the chronic stressed mice, induced by electric foot-shock. The memory improvement of the stressed mice was shown by an increase of the latency time in the step-through test and the decrease of the latency time in the Y-maze test. Treatment with ASMq was found to significantly decrease the serum levels of adrenocorticotropic hormone (ACTH), corticosterone (CORT) and β-endorphin (β-EP) as well as the brain and serum level of norepinephrine (NE). Furthermore, ASMq was able to significantly reverse the chronic stress by decreasing the brain and serum levels of the monoamine neurotransmitters dopamine (DA), 5-hydroxytryptamine (5-HT) and 3,4-dihydroxyphenylalanine (DOPAC). The results obtained from this study suggested that the memory-enhancing effect of ASMq was mediated through regulations of neurochemical and neuroendocrine systems.

Their climbing ability was also analyzed.Results:The findings of the study revealed that ASMq-treatment leads to an increase in blood serum SOD and GSH-PX levels but a decrease in blood serum MDA levels. Moreover, ASMq-treatment enhanced the survival time of mice maintained under hypoxic conditions and improved their mice climbing ability.Conclusions:The results of this study indicate that ASMq has obvious antitumor and antioxidative effects.

Development of a rapid resolution liquid chromatography-diode array detector method for the determination of three compounds in Ziziphora clinopodioides Lam from different origins of Xinjiang

Context:As a traditional Uygur medicinal plant, Z. clinopodioides Lam has various uses in Xinjiang.Aims:A reversed-phase rapid resolution liquid chromatography (RP-RRLC) method with diode array detector (DAD) was developed for simultaneous determination of diosmin, linarin, and pulegone from Ziziphora clinopodioides Lam, a widely used in traditional Uygur medicine for treating heart disease, high blood pressure, and other diseases.Settings and Design:Compounds were separated on a XDB-C18 reversed-phase analytical column (50 mm × 4.6 mm, 1.8 μm) with gradient elution using methanol and 1% aqueous acetic acid (v/v) at 0.9 mL/min. he detection wavelength was set at 270 nm.Materials and Methods:Ziziphora clinopodioides Lam. were collected from ten different origins in Xinjiang, including the Ban fang ditch, Tuoli, the Altay mountains, Terks, Xiata Road, Zhaosu Highway, Guozigou, Fukang, Jimsar, Wulabo.Statistical Analysis Used:The intra-day and inter-day precisions of all three compounds were less than 0.89% and the average recoveries ranged from 97.4 to 104.1%. There were highly significant linear correlations between component concentrations and specific chromatographic peak areas (R2 > 0.999).Results:The proposed method was successfully applied to determine the levels of three active components in Z. clinopodioides Lam. samples from different locations in Xinjiang.Conclusions:The proposed method is simple, consistent, accurate, and could be utilized as a quality control method for Z. clinopodioides Lam.

Bioassay-guided isolation of vasorelaxant compounds from Ziziphora clinopodioides Lam. (Lamiaceae)

Ziziphora clinopodioides Lam. (Lamiaceae) is traditionally used in Uighur's medicine for the treatment of hypertension. Our study determined and evaluated the bioactive compounds by performing an activity-guided fractionation of a hydroalcoholic extract of the whole plant, using an in vitro model of rat isolated thoracic aortic rings. Seven compounds were identified as active principles: acacetin, apigenin, chrysin, thymonin, acetovanillone, 4-hydroxyacetophenone and ethyl 4-coumarate. Apigenin, chrysin and ethyl 4-coumarate were found to be the most effective. Our results provide the first evidence that the vasodilation induced by Z. clinopodioides Lam. is mediated, at least in part, by phenolic components.

Vasorelaxant and hypotensive effects of a hydroalcoholic extract from the fruits of Nitraria sibirica Pall. (Nitrariaceae)

Ethnopharmacological relevanceFruits of Nitraria sibirica Pall. are traditionally used in Uighur medicine to treat hypertension. This study aimed to support that folk use by defining their vasoactive and hypotensive properties. Materials and methodsThe vasorelaxant activity and the underlying mechanisms of a hydroalcoholic extract from the fruits of Nitraria sibirica Pall. (NSHE) were evaluated on thoracic aortic rings isolated from Wistar rats. In addition, the acute hypotensive effect of NSHE was assessed in anesthetized spontaneously hypertensive rats (SHR) and in their normotensive control Wistar Kyoto (WKY) rats. ResultsNSHE (0.1–10g/l) was clearly more effective to induce vasodilation of phenylephrine- (PE, 1μM) than high KCl- (60mM) pre-contracted aortic rings with respective Emax values of 82.9±2.2% and 34.8±3.6%. The removal of endothelium almost abolished the relaxant effect of the extract. In addition, pre-treatment with Nw-nitro-l-arginine-methyl ester (l-NAME, 100μM), atropine (1μM) or charybdotoxin (30nM) plus apamin (30nM), respective blockers of nitric oxide (NO) synthase, muscarinic receptors and endothelium-derived hyperpolarizing factor (EDHF), significantly reduced the observed effect of NSHE. By contrast, the cyclooxygenase (COX) inhibitor indomethacin (10μM) or the K+ channels blockers glibenclamide (10μM), iberiotoxin (30nM) and 4-amino-pyridine (4-AP, 1mM) failed to modify the vasodilation. Finally, the acute intravenous injection of NSHE (1, 5, 10, 20mg/kg) induced an immediate and transient hypotensive effect in anesthetized SHR and in WKY rats. ConclusionsThis experimental animal study suggests that hydroalcoholic extract from the fruits of Nitraria sibirica Pall. induces vasorelaxation through an endothelium-dependent pathway involving NO synthase (NOS) activation, EDHF production and muscarinic receptor stimulation. Additionally, our results determine that this vasorelaxant effect is translated by a significant hypotensive effect.

Towards Modernization of the Formulation of the Traditional Uighur Medicine Herbal PreparationAbnormal Savda Munziq

Abnormal Savda Munziq (ASMq) is a herbal preparation used in Traditional Uighur Medicine for the treatment and prevention of diabetes, cardiovascular diseases, chronic asthma and cancer. The recommended dose of this decoction for cancer patients is 500 mL administered orally three times a day. Our approach aimed at reducing the high amount of fluid intake required by fractionation of ASMq guided by the antiproliferative activity on HL-60 cells. The fractionation of ASMq resulted in the preparation of an active extract, Extr-4. Using solid phase extraction, Extr-4 was further fractionated into five fractions (SPE-0, SPE-20, SPE-40, SPE-60 and SPE-80), with SPE-40 showing the strongest antiproliferative activity. Caffeic acid, rutin, isoquercitrin, isorhamnetin 3-O-rutinoside, apigenin 7-O-glucoside, rosmarinic acid, luteolin and formononetin were identified in Extr-4 and fractions thereof by means of TLC, HPLC-DAD and LC-MS. SPE-40 contained the main compounds responsible for the antiproliferative activity on HL-60 cells. Thus, a phenolic fraction with high antiproliferative activity on HL-60 cells was obtained from ASMq through the bioassay-guided fractionation process. This could provide a better pharmaceutical formulation that minimizes the administration inconveniencies of a high volume (1.5 L per day) of ASMq decoction for cancer patients.

ASMq ethanol extract possesses an inhibition effect on Caco-2 cells proliferation, induction of cell apoptosis, cell cycle arrest in sub-G1 phase, and downregulation of bcl-2 and upregulation of Bax gene expression. Conclusion. The anticancer mechanism of ASMq ethanol extract may be involved in antiproliferation, induction of apoptosis, cell cycle arrest, and regulation of apoptosis-related gene expression such as bcl-2 and Bax activity pathway.

Study of cytochrome P450 1A1 gene 3'-UTR 6235T-C polymorphism and susceptibility to breast cancer with Uighur medicine

To explore the association between polymorphism of cytochrome P450 1A1 Gene 3'-UTR (3'-untranslated region) 6235T-C and breast cancer with abnormal Hilit in Chinese Han population of Xinjiang. The breast cancer patients were divided into four body fluids according to Uighur medical theories. And the technique of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to detect the genotypic and allelic frequencies of 6235T-C polymorphism situated in 3'-untranslated region of CYP1A1 gene in 137 breast cancer patients with abnormal Hilit and 148 normal control subjects in Han population of Xinjiang province. (1) Significant differences in the genotypic and allelic distribution frequencies of CYP1A1 gene 3'-UTR6235T-C were found between breast cancer patients with abnormal Sapra Hilit and controls (χ(2) = 8.790, P = 0.012; χ(2) = 7.102, P = 0.008). The frequencies of CC genotype and C allele were significantly higher in breast cancer patients with abnormal Sapra Hilit (16.4% vs 39.8%) than in controls (4.7% vs 25.7%). (2) Significant differences in the genotypes and allelic distribution frequencies of CYP1A1 gene 3'-UTR6235T-C were found between breast cancer patients with abnormal Savda Hilit and controls (χ(2) = 6.638, P = 0.036; χ(2) = 5.824, P = 0.016). And the frequencies of TC, CC genotypes and C allele were significantly higher in breast cancer patients with abnormal Savda Hilit (56.9%, 9.8%, 39.2%) than those of the controls (41.9%, 4.7%, 25.7%). The CC genotype and C allele of 6235T-C polymorphism of CYP1A1 may be linked with breast cancer with abnormal Sapra Hilit and abnormal savda Hilit in Chinese Han population of Xinjiang province. But they are not correlated with the susceptibility to breast cancer with abnormal Balgham Hilit.

Antioxidant and Preventive Effects of Extract from Nymphaea candida Flower on In Vitro Immunological Liver Injury of Rat Primary Hepatocyte Cultures

Nymphaea candida is traditional Uighur medicine that is commonly used to treat head pains, cough, hepatitis and hypertension in Xinjiang of China. In this article, the extract of N. candida was measured for antioxidant activity, using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals scavenging assay and reducing power determination, and compared with those of the positive controls of butylated hydroxytoluene (BHT) and gallic acid (GA). The active extract was further purified by liquid-liquid partition to afford four fractions, of which the ethyl acetate-soluble (EA) fraction (NCE) exhibited the strongest antioxidant capacity with IC50 value of 12.6 μg/mL for DPPH. Thirteen phenolic compounds were isolated from this fraction, and they all showed significant antioxidant activities in DPPH model system. Furthermore, NCE showed potent antioxidant capacity with IC50 value of 59.32 μg/mL, 24.48 μg/mL and 86.85 μg/mL, for O2 −, ·OH and H2O2 radicals, respectively. Moreover, NCE on BCG plus LPS-induced immunological liver injury was evaluated using primary cultured rat hepatocytes. NCE produced significant hepatoprotective effects as evidenced by decreased supernatant enzyme activities (AST—aspartate transaminase, P < .01; ALT—alanine transferase, P < .01) and nitric oxide (NO, P < .01) production. These results revealed the in vitro antioxidant and hepatoprotective activities of NCE against immunological liver injury. Further investigations are necessary to verify these activities in vivo.

Inhibition of Cell Growth and Cellular Protein, DNA and RNA Synthesis in Human Hepatoma (HepG2) Cells by Ethanol Extract of Abnormal Savda Munziq of Traditional Uighur Medicine

Abnormal Savda Munziq (ASMq) is a traditional Uighur medicinal herbal preparation, commonly used for the treatment and prevention of cancer. We tested the effects of ethanol extract of ASMq on cultured human hepatoma cells (HepG2) to explore the mechanism of its putative anticancer properties, using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) bromide, neutral red and lactate dehydrogenase (LDH) leakage assays, testing the incorporation of 3[H]-leucine and 3[H]-nucleosides into protein, DNA and RNA, and quantifying the formation of malondialdehyde-thiobarbituric acid (MDA) adducts. ASMq ethanol extract significantly inhibited the growth of HepG2 and cell viability, increased the leakage of LDH after 48 hours or 72 hours treatment, in a concentration- and time-dependent manner (P < .05). Cellular protein, DNA and RNA synthesis were inhibited in a concentration- and time-dependent manner (P < .05). No significant MDA release in culture medium and no lipid peroxidation in cells were observed. The results suggest that the cytotoxic effects of ASMq ethanol extract might be related to inhibition of cancer cell growth, alteration of cell membrane integrity and inhibition of cellular protein, DNA and RNA synthesis.
