Purpose: In this article, the products and effects of dandelions are reviewed to help further in-depth studies and develop more products derived from dandelions in the future. Method: The literature about dandelion in various databases such as Pubmed is searched. Results: Dandelions have many effects, such as virus inhibition, anti-tumor activity, nutritional value, anti-aging, potential as a vaccine and alleviation of heat stress. The mechanism underlying these effects is analyzed and it was found that dandelions were regulated by RNA or DNA. Conclusion: As a medicinal and food, dandelions are safe and have many effects. Many products derived from dandelions have been developed. The metabolic regulation is related with ribonucleic acid or possibly deoxynucleic acid. Further in-depth studies should be conducted on the regulation of dandelions through RNA or DNA. There will likely be more products derived from dandelions in the future.展开更多

In spite of all the research on diabetes and recent advances in diabetes treatments, the reality is that there is no cure for diabetes and its devastating complications. While currently available anti-diabetic therapies are effective in reducing blood glucose level, they are not without associated side effects when they are used for a long term applications. As a result, physicians and patients are inclining more towards to a safer therapy with less serious side effects in the form of medicinal foods and botanical alternatives that are suitable for chronic usage. Aloesin, an Aloe chromone, has previously been formulated with an aloe polysaccharide to give a composition called Loesyn, where it showed significant impact in reducing glycosylated hemoglobin, fasting blood glucose, fructosamine and plasma insulin level in humans. Radical scavenging activities of chromones and polysaccharides from Aloe have also been reported. Here we rationalize the relevance of use of Aloesin alone or in a standardized blend with Aloe polysaccharides, as a potential medical food to manage systemic oxidative stress and/or high blood glucose of diabetes.展开更多

The convention of using just a selected few Chemical Reference Substances (CRS) cannot adequately assess the quality of intact CHM. A validated chemical spectrum of an ERS provides the global characteristics in order to more specifically identify and assess targeted CHM. This paper describes the fundamental concepts, potential significance, and basic criteria of ERS, along with methods of preparation and calibration. Given the diversity of CHM, the various problems that will occur in establishing the proper process of ERS will need to be solved in a step by step manner. The ERSs of Ziziphi spinosae semen and ERS of Fritillaria thunbergii bulbus are given as examples of the development of ERS and demonstrate why we are optimistic about the utility of this approach.展开更多

METHODS: Thirty baby rats for IBS modeling were separated from mother rats(1 h per day) from days 8 to 21, and the rectum was expanded by angioplasty from days 8 to 12. Ten normal rats were used as normal controls. We examined the effects of TXYF on defection frequency, colonic transit function and smooth muscle contraction, and the expression of 5-hydroxytryptamine(5-HT) and substance P(SP) in colonic and hypothalamus tissues by Western blot and RT-PCT techniques in both normal rats and IBS model rats with characterized visceral hypersensitivity.in normal rats and 4.5 ± 1.58 in IBS model rats(P < 0.001). However, the defecation frequency was significantly decreased(3.0 ± 1.25 vs 4.5 ± 1.58, P < 0.05), while the time(in seconds) of colon transit function was significantly increased(256.88 ± 20.32 vs 93.36 ± 17.28, P < 0.001) in IBS + TXYF group rats than in IBS group rats. Increased colonic smooth muscle tension and contract frequency in IBS model rats were significantly decreased by administration of TXYF. Exogenous agonist stimulants increased spontaneous activity and elicited contractions of colon smooth muscle in IBS model rats, and all of these actions were significantly reduced by TXYF involving 5-HT and SP down-regulation. CONCLUSION: TXYF can modulate the activity of the enteric nervous system and alter 5-HT and SP activities, which may contribute to the symptoms of IBS.展开更多

DC., the first Brazilian variety of medicinal plant, in response to five doses of organic fertilizer (0, 10, 20,30, 40 and 50 ton/ha) over two harvest moments-120 d and 242 d after transplanting (DAT). The work was carried out fromFebruary to October 2011 at the experimental farm of the Sao Paulo State University "Julio de Mesquita Filho" (UNESP), Brazil.The seedlings of B. trimera var. CPQBA-1 were respectively transplanted into experiment plots under six treatments: 0, 10, 20, 30,40 and 50 ton/ha of organic fertilizer. Each treatment had four replications and each plot consisted of 12 plants. Then they wereharvested at 120 DAT and 242 DAT, and the essential oil were extracted by hydrodistillation and analyzed by gas chromatograph.The results were subjected to analysis of variance and the means were analysed using Tukey's test (5%) followed by a regressionanalysis. The fertilizer dose significantly influenced the height of the plants in the second harvest, while the higher dose of organicfertilizer positively impacted the essential oil content in the first harvest. Also, the level of organic fertilizer was directly correlatedwith the production of dry matter during the regrowth. Twenty-seven substances were identified in the essential oil samples, and themajor components were: bicyclogermacrene, trans-caryophyllene, germacrene-D, spathulenol and caryophyllene oxide. Thesefindings suggest that to obtain higher yields of dry matter ofB. trimera, it should be harvested around 242 DAT and organic fertilizershould be applied approximately to 50 ton/ha. Furthermore, higher doses of organic fertilizer and harvest at 120 DAT is able toincrease the essential oil content.展开更多

Given the diversity of CHM, the various problems that will occur in establishing the proper process of ERS will need to be solved in a step by step manner. The ERSs of Ziziphi spinosae semen and ERS of Fritillaria thunbergii bulbus are given as examples of the development of ERS and demonstrate why we are optimistic about the utility of this approach.

文摘AIM: To investigate whether the Chinese medicine Tong Xie Yao Fang(TXYF) improves dysfunction in an irritable bowel syndrome(IBS) rat model. METHODS: Thirty baby rats for IBS modeling were separated from mother rats(1 h per day) from days 8 to 21, and the rectum was expanded by angioplasty from days 8 to 12. Ten normal rats were used as normal controls. We examined the effects of TXYF on defection frequency, colonic transit function and smooth muscle contraction, and the expression of 5-hydroxytryptamine(5-HT) and substance P(SP) in colonic and hypothalamus tissues by Western blot and RT-PCT techniques in both normal rats and IBS model rats with characterized visceral hypersensitivity.in normal rats and 4.5 ± 1.58 in IBS model rats(P < 0.001). However, the defecation frequency was significantly decreased(3.0 ± 1.25 vs 4.5 ± 1.58, P < 0.05), while the time(in seconds) of colon transit function was significantly increased(256.88 ± 20.32 vs 93.36 ± 17.28, P < 0.001) in IBS + TXYF group rats than in IBS group rats. Increased colonic smooth muscle tension and contract frequency in IBS model rats were significantly decreased by administration of TXYF. Exogenous agonist stimulants increased spontaneous activity and elicited contractions of colon smooth muscle in IBS model rats, and all of these actions were significantly reduced by TXYF involving 5-HT and SP down-regulation. CONCLUSION: TXYF can modulate the activity of the enteric nervous system and alter 5-HT and SP activities, which may contribute to the symptoms of IBS.

文摘Delaying the onset of aging is considered an important tool for dealing with the global crisis of the aging population.Accordingly,several antiaging studies have been conducted using strategies of modern medicine and traditional Chinese medicine(TCM).In this review,we summarize the current state of antiaging research related to both modern medicine and TCM and provide suggestions for further research.Various theories related to the aging process have been proposed,including the free radical theory,mitochondrial DNA damage theory,telomere theory,cross-linking theory,and intestinal flora theory,and a number of antiaging chemical treatments have been developed using modern medicine.These theories and achievements have resulted in major advancements in antiaging research.TCM is based on practical experience and has a long history with unique advantages in antiaging research.Some antiaging practices such as moderate diet consumption,acupuncture,Tai Chi(a traditional Chinese martial art that can relax the nerves to slow down the aging process),and Wuqin Xi(a traditional Chinese exercise to strengthen the body)have been adopted to maintain health.Several TCMs and prescriptions,particularly those related to medicine food homology,have been used in antiaging treatment,and their antiaging properties have been demonstrated to be effective based on pharmacological experiments and clinical applications.
文摘This study aimed to investigate, for the first time, the plant growth, essential oil content and their chemical substances ofBaccharis trimera (Less.) DC., the first Brazilian variety of medicinal plant, in response to five doses of organic fertilizer (0, 10, 20,30, 40 and 50 ton/ha) over two harvest moments-120 d and 242 d after transplanting (DAT). The work was carried out fromFebruary to October 2011 at the experimental farm of the Sao Paulo State University "Julio de Mesquita Filho" (UNESP), Brazil.The seedlings of B. trimera var. CPQBA-1 were respectively transplanted into experiment plots under six treatments: 0, 10, 20, 30,40 and 50 ton/ha of organic fertilizer. Each treatment had four replications and each plot consisted of 12 plants. Then they wereharvested at 120 DAT and 242 DAT, and the essential oil were extracted by hydrodistillation and analyzed by gas chromatograph.The results were subjected to analysis of variance and the means were analysed using Tukey's test (5%) followed by a regressionanalysis. The fertilizer dose significantly influenced the height of the plants in the second harvest, while the higher dose of organicfertilizer positively impacted the essential oil content in the first harvest. Also, the level of organic fertilizer was directly correlatedwith the production of dry matter during the regrowth. Twenty-seven substances were identified in the essential oil samples, and themajor components were: bicyclogermacrene, trans-caryophyllene, germacrene-D, spathulenol and caryophyllene oxide. Thesefindings suggest that to obtain higher yields of dry matter ofB. trimera, it should be harvested around 242 DAT and organic fertilizershould be applied approximately to 50 ton/ha. Furthermore, higher doses of organic fertilizer and harvest at 120 DAT is able toincrease the essential oil content.

文摘Objective:Jue tone is a kind of sound,using 3-mi as the main tone,and is melodious,profound,makes people feel comfortable and pleasant.This study aimed to explore the probable mechanism of Jue tone to reduce blood pressure(BP)in hypertensive rats with a liver-fire hyperactivity pattern by observing changes in BP as well as physiochemical indexes in plasma.Methods:Sixteen male spontaneous hypertensive rats(SHR)with a liver-fire hyperactivity pattern were randomly divided into a control group and a Jue tone group.The rats in the Jue tone group were treated with Jue tone(55e65 dB,played by the five elements of music rhythm instrument,a kind of physiotherapy regimen music played by Shen Wu)once a day for 4 weeks.The BP levels in each group were measured twice a week,on Monday and Friday.The levels of angiotensin II(Ang-II),thromboxane B2(TXB2),endothelin-1(ET-1),calcitonin gene-related peptide(cGRP),norepinephrine(NE),cortisol(CORT),and 5-hydroxytryptamine(5-HT).in plasma were detected by enzyme-linked immunosorbent assay after 4 weeks of intervention.Results:BP and the levels of TXB2 and ET-1 in the plasma of the treatment group were significantly lower than those of the control group,while the level of cGRP was significantly higher.Conclusion:Jue tone can reduce the BP of hypertensive rats with a liver-fire hyperactivity pattern.The mechanism may correlate with a reduction in TXB2 and ET-1 and an increase in cGRP with the reduction of reactive oxygen species(ROS).
文摘In the world there are many collections of the pharmaceutical trend.In America,the exhibits of this profile are in the Smithsonian Museum of Natural History in Washington,in Europe these are collections of pharmacy museums in Heidelberg(Germany),Krakow and Warsaw(Poland),Basel(Switzerland),Riga(Latvia),and others.Some of them have many thousands of exhibits.There are also separate collections of pharmaceutical items for educational institutions,for example,a collection of old medicinal raw materials in Vigan’s Cabinet,Queen College,Cambridge(Great Britain).All these meetings,however,have long been known and described in detail.Most of them do not have a strict orientation and are presented,along with old medicinal raw materials,as well as tools and appliances,dishes,books,herbaria and various auxiliary items.All the more interesting is the collection indicated in the title of the article,which arose literally from non-existence.She was transferred to the educational institution at its creation,and this year she,like him,turns a hundred years old.It has a strict focus and is represented almost exclusively by medicinal raw materials.Studying the samples of this old collection,as a whole of medical profile,makes it possible to understand that many plants,which initially had only food use,gradually became pharmaceutical objects.Probably,it was the long practice of food use,with the fixing of associated pharmacological effects in the memory,that became the reason for choosing certain types of raw materials as medicinal.Ordinary foods,protein and starchy,began to be perceived as strengthening,mucous—as enveloping and anti-ulcer,some fruits and herbs—as antiscorbutic,sharp—as appetizing and improving the work of the stomach,and so on.
文摘Background:The nutrients in eggs play an important role in the health of different body organs like the brain,cardiometabolic system,musculoskeletal system,skin and eyes and so the eggs can be considered as functional foods.In order to maintain the highest nutrient content of an egg,it is recommended to cook it properly,but no specific clinical research has been carried out yet on the role that the cooking of an egg plays in its food and health properties.For this reason,this study has collected and discussed the topics related to a variety of methods of cooking eggs,based on the texts of Persian Medicine,and conducted a comparison with modern sources of nutrition.Methods:The present study is a review in which sources of Persian Medicine(PM)were searched in software JamiTib(Version 1.5)and Persian electronic banks,sites of PubMed,Google Scholar,ScienceDirect,and Embase and websites of health reference of American food and water.Finally,the results obtained were classified and a content analysis was carried out.Results:In the PM books,in addition to referring to the different properties of eggs,different effects of different egg preparation have been investigated.The wise men of the school of medicine have proposed at least five methods of egg preparation,including very soft boiled,soft-boiled,hardboiled,fried,and omelet.In the texts,the healing properties of each case and the quality of digestion in the body were separately investigated.Among the five main methods of preparation eggs,the therapeutic and digestive effects of soft-boiled eggs are emphasized to a greater extent,because easy digestion leads to more beneficial effects of the yolk of the eggs.Conclusion:Though the wise men of Persian Medicine have proposed a variety of methods to cook eggs,ease of digestion is one of the most important factors in their decision-making while proposing the type of cooking method for therapeutic prescriptions.In contrast,in modern nutrition research,regardless of the method of cooking eggs,the effect of its use on diseases like heart disease or diabetes has been studied.Owing to the fact that many cases of eggs,as mentioned,have been confirmed in PM texts during modern scientific surveys,it appears that clinical studies on the relevant issues of eggs in this context are useful in better understanding therapeutic effects.
