A Review on Medicinal Plants with Anti-Ulcer Activity

A peptic ulcer is erosion in a segment of the gastro intestinal mucosa. It may typically in the stomach (gastric ulcer) or first few centimeters of duodenum (duodenal ulcer) that penetrates through the muscularis mucosae. Contrary to popular belief, ulcer is not only caused by spicy food but also most commonly due to an infection of Helicobacter Pylori and long term use of medications. Standard treatment is a combination of drugs including antibiotics and a proton pump inhibitors. Literature suggests that number of synthetic drugs are used in the management of peptic ulcers but elicit several adverse effects. Therefore Indian herbal plants stand out as being exceptional for its ethnic, ethobotanical and ethno-pharmaceutical use. In this review attempts have been made to know about some plants which may be used in treatment or prevention of peptic ulcers. Various plants like Excoecaria agallocha, Mentha arvensis, Utleria salicifolia, Emblica officinalis etc. proved active in antiulcer therapy. This combination of traditional and modern knowledge can produced better antiulcer drugs with fewer side effects. The medicinal plants are available in India and other countries, recent technologies advances have renewal interest in natural product in drug discovery.

A review of antimalarial plants used in traditional medicine in communities in Portuguese-Speaking countries: Brazil, Mozambique, Cape Verde, Guinea-Bissau, São Tomé and Príncipe and Angola

A review of antimalarial plants used in traditional medicine in communities in Portuguese-Speaking countries: Brazil, Mozambique, Cape Verde, Guinea-Bissau, São Tomé and Príncipe and Angola

The isolation of bioactive compounds from medicinal plants, based on traditional use or ethnomedical data, is a highly promising potential approach for identifying new and effective antimalarial drug candidates. The purpose of this review was to create a compilation of the phytochemical studies on medicinal plants used to treat malaria in traditional medicine from the Community of Portuguese-Speaking Countries (CPSC): Angola, Brazil, Cape Verde, Guinea-Bissau, Mozambique and São Tomé and Príncipe. In addition, this review aimed to show that there are sev- eral medicinal plants popularly used in these countries for which few scientific studies are available. The primary approach compared the antimalarial activity of native species used in each country with its extracts, fractions and isolated substances. In this context, data shown here could be a tool to help researchers from these regions establish a scientific and technical network on the subject for the CPSC where malaria is a public health problem.

Biological properties of medicinal plants: a review of their antimicrobial activity

Biological properties of medicinal plants: a review of their antimicrobial activity

he use of plants for treating diseases is as old as the human species. Popular observations on the use and eicacy of medicinal plants signiicantly contribute to the disclosure of their therapeutic properties, so that they are frequently prescribed, even if their chemical constituents are not always completely known. All over the globe, especially in South American countries, the use of medicinal plants has signiicantly supported primary health care (1). From 250 to 500 thousand plant species are estimated to exist on the planet, and only between 1 and 10% are used as food by humans and other animals (2). Brazil has the world’s highest biodiversity, accounting for over 20% of the total number of known species. his country presents the most diverse lora, with more than 55

Medicinal plants Antimicrobial Activity against Staphylococcus spp. – Literature Review / Atividade antimicrobiana de plantas medicinais contra Staphylococcus spp. – Revisão de Literatura

Joseph Lister at 1860 believed that the infection was caused by the harmful air penetration on wounds, saying that “the atmosphere septic properties” were due to the germs in suspension in the air and deposited in surfaces. Then, passed to use carbolic or phenoic acid, which were already widely used to disinfect latrines, stables and sewage, from observing the phenoic acid decreased the sewage odor and the cattle from such place were less sick. From there, they started to test in animals and humans and succeed after the application. Surgery rooms started to be sprayed with phenoic acid and, later, passed to use carbolic acid to instrumental disinfection. In 1883, Pasteur and Charles Chamberland, autoclave creators, showed that the sterilization by heating had superior efficacy (Pelczar Junior and Chan, 1996; Rodrigues, 1997).

A review on medicinal plants used for treating ototoxicity and acoustic trauma induced hearing loss

A review on medicinal plants used for treating ototoxicity and acoustic trauma induced hearing loss

Both cisplatin and aminoglycoside drugs cause neural-sensory hearing loss at high frequencies, which is accompanied by the loss of outer hair cells in the basal turn of the cochlea (Rybak, Ramkumar 2007; Xiong et al., 2015). Both drug groups play a role as an early stimulus for cell damage and cell death through increased oxidative stress in the ear. The main mechanism of neural-sensory cell damage by cisplatin is through the apoptosis pathway, while for aminoglycosides, it appears to be via the induction of both apoptosis and necrotic pathways. Experimental studies on animals have shown that different types of antioxidants can reduce the ototoxicity caused by aminoglycosides or cisplatin without any interference with drug effectiveness and thus appear as promising therapeutic agents.(Kim et al., 2010; Okada et al., 2012) In this regard, reported in several studies the positive effects of the medicinal herbs such as Korean Red Ginseng (Tian et al., 2013), Astragalus membranaceus (Xiong et al., 2011), Maytenus ilicifolia (Kasse et al., 2008), and Astragaloside IV (Xiong et al., 2011) on the reduction of cisplatin induced ototoxicity by, and others such as Salvia miltiorrhiza (Wang et al., 2003) and Korean Red Ginseng (Tian et al., 2013) on the reduction of aminoglycosides induced ototoxicity. Most plants inhibit the formation of free radicals of ROS and RNS due to their antioxidant properties and prevent the activation of the apoptosis pathway in the cochlea hair cells by inhibiting Caspase3. Anumber of herbal remedies use other mechanisms to improve hearing loss. Radix astragali prevents hearing loss caused by acoustic trauma through inhibiting the reduction of Connexin 26 and KCNQ1 gene expression in StriaVascularis (Xiong et al., 2015). CAE prevents noise-induced hearing loss through its antioxidant, anti-inflammatory, and DNA repair mechanisms (O’Neil et al., 2011). Purple Bamboo Salt is used to treat tinnitus and cisplatin induced hearing loss from (Hong, Lyu, 2011). This compound has an anti-inflammatory property and prevents inner and outer hair cell death, preventing the release of cytochrome C and caspase-3 and inhibiting inflammatory factors. The main focus of this article was to review the important

Biological effects of medicinal plants on induced periodontitis : a systematic review

Biological effects of medicinal plants on induced periodontitis : a systematic review

Periodontal disease initiation and progression occur as a consequence of the host response to microorganisms of the dental bioilm [1]. herefore, the antibacterial efect is an important factor in the periodontal therapy. Only 26.6% of the studies investigated the capacity of the material to present antibacterial activity. In the study developed by Barrella et al. [24] the organic extract obtained from Ipomoea alba showed signiicant in vitro activity against Streptococcus mutans, S. sanguinis, and Enterococcus faecalis. he commercial prod- uct Magnolol obtained from Magnolia oicinalis exhibited intense inhibition of Porphyromonas gingivalis and Aggregat- ibacter actinomycetemcomitans growth in a dependent dose [11] and the aqueous extract from Vaccinium macrocarpon containing tannin and phenolic compounds inhibited the adhesion of Fusobacterium nucleatum and Porphyromonas gingivalis [15].Study developed by Botelho et al. [25] and Botelho et al. [26] with Lippia sidoides observed the decrease of salivary bacterial levels and this event was followed by an increment in clinical scores of gingival bleeding. Except for the work published by Klausen et al. [8] which did not evaluate the alveolar bone loss, all the articles that described the identiication of antibacterial activity also demonstrated that plant material treatment induced a signiicant reduction of alveolar bone loss.

Integrative approach to analyze biodiversity and anti-inflammatory bioactivity of Wedelia medicinal plants.

Integrative approach to analyze biodiversity and anti-inflammatory bioactivity of Wedelia medicinal plants.

To determine the possible specific anti-inflammatory functions of Wedelia species, we used a DSS-induced acute murine colitis model to evaluate the bioactivities of various Wedelia herbal extracts. Throughout the experiment, we monitored the oral intake of drinking water spiked with 2.0% DSS: the consumption level of DSS-spiked water was found to be statistically indis- tinguishable among all test groups (data not shown). Sulfasalazine, a commercialized drug for treating and preventing relapse of IBD was used as the positive control for this experiment [39,40]. Under normal conditions, i.e., DSS was not added to drinking water, Wedelia herbal extracts did not promote mouse body weight loss (data not shown). Mice treated with 2% DSS in drinking water developed typical symptoms of acute colitis including diarrhea, rectal bleed- ing and loss of body weight. Comparison of the DSS group with the vehicle group showed that the relative body weight (%) of the DSS-treated group decreased significantly on days 6, 7 and 8 (Fig 6A). After treatment with 2% DSS, mouse body weights were found to be significantly lower in the DSS, sulfasalazine (Sul), WB, WP and WPR-treated groups than in the WC and WT groups on days 7 and 8 (Fig 6A). The disease activity index (DAI) was calculated accord- ing to the severity of clinical colitis symptoms (S1 Table). Statistical analysis revealed that the DAI scores for various Wedelia species groups were not significantly different from that for the DSS group (Fig 6B). Although we can not co-relate clearly the bioactivities of different Wedelia plant extracts to the DAI score, we consider that the specific difference between the WC and DSS only group is in agreement with other data shown in Fig 6 and as we previously reported [9]. Decrease in colon length is widely accepted as a critical symptomatic parameter in DSS-induced colitis. Fig 6C shows that the colon length of test mice was significantly de- creased after eight days of DSS administration. A comparison of the Wedelia extract-treated

Natural Compounds from Mexican Medicinal Plants as Potential Drug Leads for Anti-Tuberculosis Drugs

Natural Compounds from Mexican Medicinal Plants as Potential Drug Leads for Anti-Tuberculosis Drugs

In Mexican Traditional Medicine 187 plant species are used in the treatment of respiratory conditions that may be associated with tuberculosis. In this contribution, we review the ethnobotany, chemistry and pharmacology of 63 species whose extracts have been assayed for antimycobacterial activity in vitro. Among these, the most potent is Aristolochia brevipes (MIC= 12.5 µg/mL), followed by Aristolochia taliscana, Citrus sinensis, Chrysactinia mexicana, Persea americana, and Olea europaea (MIC<64 µg/ mL). Other potent extracts (inhibition > 95%, 50 µg/mL) include: Amphipterygium adstringens, Larrea divaricata, and Phoradendron robinsoni. Several active compounds have been identified, the most potent are: Licarin A (isolated from A. taliscana), and 9-amino-9-methoxy-3,4-dihydro-2H-benzo[h]-chromen-2- one (transformation product of 9-methoxytariacuripyrone isolated from Aristolochia brevipes), both with MIC= 3.125 µg/mL, that is 8-fold less potent than the reference drug Rifampicin (MIC= 0.5 µg/mL). Any of the compounds or extracts here reviewed has been studied in clinical trials or with animal models; however, these should be accomplished since several are active against strains resistant to common drugs. Key words: Tuberculosis, medicinal plants, natural products, Mycobacterium tuberculosis.

ANTIMICROBIAL ACTIVITY OF MEDICINAL PLANTS AGAINST DIFFERENT STRAINS OF BACTERIA

ANTIMICROBIAL ACTIVITY OF MEDICINAL PLANTS AGAINST DIFFERENT STRAINS OF BACTERIA

This in vitro study demonstrated that folk medicine can be as effective as modern medicine to combat pathogenic microorganisms. The millenarian use of these plants in folk medicine suggests that they represent an economic and safe alternative to treat infectious diseases. Interest in plants with antimicrobial properties has been revived as a result of antimicrobial resistance. Although a great amount of research has been performed to determine the antibacterial activity of medicinal plants, optimal extraction of bioactive compounds has not been well established. It is clear from the results that, the extracts act as a good source of antimicrobial agent against Pseudomonas aeruginosa and Listeria ivanovii.

Drug Interaction with Radiopharmaceuticals: a Review

Drug Interaction with Radiopharmaceuticals: a Review

A variety of iatrogenic physical and other aggressions that cause identifiable changes in images (SPECT and PET) are described. The nature of these abnormalities and the profusion of isolated reports concerning them may, at first, be intimidating. Most, if not all, of these abnormalities, however, might be anticipated from an understanding of the disease processes of a particular patient, and from insight into the mechanisms of the radiobiocomplex behavior. Therefore, this review emphasizes the importance of understanding the SPECT and PET images as an aspect of the patient care and not as abstract exercises divorced from the conditions of human beings in several aspects. In conclusion, the knowledge about the DIR and the other factors capable of interfering with the bioavailability of the radiobiocomplexes is very important for secure diagnosis. In addition, the development of biological models to study this phenomenon is highly relevant and desired.

Evaluation of Gastric Anti-ulcer Activity in a Hydro- ethanolic Extract from Kielmeyera coriacea

Evaluation of Gastric Anti-ulcer Activity in a Hydro- ethanolic Extract from Kielmeyera coriacea

Anti-inflammatory drugs like Indomethacin administered in toxic doses (20 mg/kg), produce visible gastric ulcers in animals. Indomethacin is a potent inhibitor of prostaglandin biosynthesis (Vane, 1971). Prostaglandins are known to play an important role in maintaining mucosal integrity. An Increase in certain endogenous prostaglandins can enhance gastric mucosal resistance to ulcerogenic agents (Robert, 1979). The mechanisms involved in prostaglandin action are multiple, including stimulation of mucus and bicarbonate output (Hogan et al., 1994), gastric mucosal blood flow (Gaskil et al, 1982), decreasing gastric motility, increasing the release of endogenous mediators of gastric injury- vasoactive amines and leucotrienes and stimulation of cellular growth and repair (Hawkey and Rantim, 1985). In the present study, the effect of the extract on prostaglandin biosynthesis was not evaluated, but an increase in resistance to the necrotizing effect of Indomethacin was noted. Ethanol-acid causes more severe gastric mucosal
