RESUMO

Currently, the use of alternative medicine is necessary, even in animals. Our study focused on the valorisation of the use of herbal products in Algerian veterinary medicine. This study is based on a 6-month exploratory survey of 257 private practicing veterinarians, followed by a study of the bacteriological activity of the essential oil of the Pistacia lentiscus plant. The survey results generally indicate that private veterinarians support phytotherapy as an alternative to conventional drugs in several areas and species. Also, the results of research conducted on the antibacterial activity of Pistacia lentiscusessential oil show that it inactivates 50% of the bacterial strains. This confirms the well-defined role of this medicinal plant used as an alternative in veterinary medicine.(AU)

RESUMO

In order to evaluate the potential of this formulation (P. lentiscus L. oil-based ointment) to heal wounds, experimental wounds were done on guinea pigs and efficiency was comparatively assessed against a reference ointment, Cicaderma®. Wound contraction was performed on days 5, 10 and 15. Tissue sections were also evaluated histopathological on days 7, 14 and 21. Results showed that for all days (5, 10 and 15), the highest wound contraction values were attained for the P. lentiscus oil-based ointment treated group with wound contraction values of 19.38, 55.8 and 77.11%, respectively, as compared to the reference drug Cicaderma® where contractions were 7.97%, 49.53% and 71.44%, respectively. Vehicle and negative control groups however showed no statistically significant wound healing activity on the excision wound model. These experimental studies revealed that the P. lentiscus oil-based ointment displays remarkable wound healing activity, in accordance with its use in traditional medicine.

RESUMO

BACKGROUND: The Pink peppercorn belongs to the same Anacardiaceae family as cashew and pistachio. However, the cross-reactivity of pink peppercorn with cashew and pistachio has yet to be studied. To date, there has been a single case report of anaphylaxis to pink peppercorn in a cashew and pistachio allergic individual. OBJECTIVE: We aim to demonstrate cross-sensitization to pink peppercorn in cashew and/or pistachio allergic children. METHODS: A small descriptive cohort study looking at cross-sensitization of pink peppercorn in cashew and/or pistachio allergic children was conducted. Children with a history of reaction to pistachio and/or cashew nut underwent skin prick tests to the pink peppercorn species Schinus terebinthifolius to determine cross-sensitization. RESULTS: Out of the 21 cashew and/or pistachio allergic subjects, 16 (76.2%) demonstrated cross-sensitization to pink peppercorn. None of the subjects had any knowledge of previous exposure or allergic reactions to pink peppercorn. DISCUSSION: This study demonstrates potential cross-reactivity between pink peppercorn and cashew and pistachio. While an oral food challenge to pink peppercorn would have been important in demonstrating clinical cross-reactivity, this was not performed due to ethical constraints. We hope to increase the awareness of pink peppercorn as a potential and hidden source of allergen and encourage further studies to demonstrate the clinical cross-reactivity and to better delineate the major allergen involved.

RESUMO

Pistacia lentiscus,which belongs to foreign medicine resources,is widely distributed in the Mediterranean and Middle Eastern area. The essential oils are a mixture of several volatile compounds mainly monoterpenes and sesquiterpenes obtained from different parts of P. lentiscus by hydrodistillation. The variability of chemical composition,biological activities and content of essential oil is strongly affected by extraction technology,environmental and sex factors. It is indicated that essential oils of P. lentiscus have kinds of biological activities such as antibacterial,anticancer,anti-atherogenesis,antioxidant,anti-inflammatory and insecticidal activities.Many scholars hold the opinion that combination of different components with synergistic and/or additive actions should account for their biological activities. Due to its diverse efficacy and special taste,the essential oil of P. lentiscus has been extensively used in medicine,food and cosmetics industries. A mini review of chemical constituents and biological activities of essential oil of P. lentiscus in the past20 years is made here to provide valuable reference for the construction of " the Belt and Road".

RESUMO

BACKGROUND: There has been an increasing trend of nut allergies in Singapore. OBJECTIVE: The aim of this study was to review the clinical characteristics of children with cashew nut allergy. METHODS: A retrospective analysis was conducted in a tertiary paediatric referral centre in Singapore from 2008 to 2015. A total of 99 subjects with positive specific IgE (≥0.35 IU/L) to cashew nut were identified. Clinical features including demographics, clinical reaction to cashew nut, associations with other nuts and test specific measurements were recorded. RESULTS: The results showed that cutaneous symptoms (71.2%) were the most common allergic manifestations. Anaphylaxis occurred in 3.8% of children. In addition, all cashew nut allergic subjects were cross-reactive (either sensitized or allergic) to pistachio. Cross-reactivity rate with peanuts was 53.8%. There was a strong prevalence of atopy among cashew nut allergic subjects. CONCLUSION: In conclusion, cashew nut allergy is a significant tree nut allergy in Singapore.

RESUMO

OBJECTIVES: Stillbirth is an undesirable outcome of pregnancy. In light of the increasing use of pesticides and growing concerns about the possible health effects of agricultural pesticides, we investigated the effect of exposure to pistachio pesticides on stillbirth in pregnant mothers. METHODS: This case-control study was conducted in Rafsanjan, Iran from 2011 to 2012. A total of 125 females who had a recent stillbirth were included as the case group, and 250 controls were selected from females who had a recent live birth. For each case, two controls with the nearest propensity score to the case were selected. Data were collected using a protocol developed by the researcher that involved interviewing respondents and reviewing their medical records. Conditional multivariate and univariate logistic regression analysis were performed and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS: The ORs of stillbirth in mothers living in pistachio gardens and those who were exposed to sprayed pesticides, in comparison to the controls, were 14.1 (95% CI, 3.3 to 63.4) and 5.0 (95% CI, 1.2 to 28.6), respectively. No significant differences were found in stillbirth rates according to the distance between the mother's residence and a pistachio garden or involvement in agricultural activities. CONCLUSIONS: The results of our study showed that exposure to pistachio pesticides during pregnancy may increase the likelihood of stillbirth in mothers.

RESUMO

OBJECTIVES: Mastic is a resinous extract from the stem and main leaves of Pistacia lentiscus, grown only in the Chios island of Greece. Mastic has antibacterial, anti-inflammatory, anticancer, and anti-ulcer activities. Although mastic has been widely studied, its inhibitory effect against cancer cells, especially oral cancer cells, has not been elucidated. The purpose of this study was to assess the anticancer effects of mastic on human oral cancer YD-10B cells. METHODS: YD-10B cells were cultured in 0, 1, 2, 5, and 10 µg/mL mastic for 24 h. Cell count, viability, morphology, colony-forming assay, and DAPI staining were analyzed. RESULTS: Mastic treatment of YD-10B cells resulted in a dose-dependent inhibition of cell growth, and almost all the cells in the 10 µg/mL culture were dead (P<0.05). Mastic treatment induced a morphological change and nuclear fragmentation in the YD-10B cells, and inhibited colony formation of YD-10B cells in a dose-dependent manner. CONCLUSIONS: These results indicate that mastic exhibited anticancer effects on the YD-10B cells through changes in cell morphology and apoptosis.

RESUMO

AIM@#The current study was undertaken to assess anti-hyperlipidemic activity of Pistacia lentiscus fatty oil (PLFO) in rabbits following a hyperlipidemic diet.@*METHOD@#Twenty healthy female (WNZ) rabbits were divided into four groups of five animals each: (a) normal control (NC group) receiving standard diet, (b) hyperlipidemic control (EY) group receiving standard diet and gavaged daily with egg yolk (10 mL), (c) hyperlipidemic + PLFO (EY + PLFO) group receiving as the EY group and treated daily with PLFO (2 mL/kg BW, (d) hyperlipidemic + simvastatin (EY + SVS) group receiving as the EY group and treated once daily with 2.5 mg/kg BW of simvastatin. At the end of the six-week experimental period, the lipidemic profiles of the different groups were investigated.@*RESULTS@#In the EY group, the egg yolk resulted in a significant increase of total cholesterol (TC), triglycerides (TG), HDL-C, LDL-C, and the LDL-C/HDL-C ratio. Both the EY + PLFO and EY + SVS groups, when compared to the EY group, showed a significant decrease of TC, TG, LDL-C, and the LDL-C/HDL-C ratio. However, with respect to HDL-C the differences were not significant. The TGs were significantly lower (P < 0.001) in the simvastatin-treated group when compared to rabbits treated in the PLFO group.@*CONCLUSION@#The study concludes that P. lentiscus fatty oil (PLFO) possesses anti-hyperlipidemic properties at least in reducing total cholesterol, LDL-cholesterol and triglycerides.

RESUMO

The effects of exercise training on GLUT4 protein expression have been examined in several studies whereas those of aerobic training along with the use of plant extracts on muscle GLUT4 protein expression are unknown. The aim of the present study was to investigate the effects of aerobic training and Pistacia athlantica extract on GLUT4 protein expression and glycogen level in the gastrocnemius muscle of diabetic rats. Forty-male Wistar rats were randomly divided into five groups: Healthy control, diabetic control, diabetic+ aerobic training, diabetic+extract and diabetic+ aerobic training+ extract. The program included six weeks of aerobic training on the treadmill. Forty eight hours after last session of training and consumption the extract, the rats were anesthetized and gastrocnemius muscle was isolated for measurement of glycogen levels and GLUT4 protein expression. Data was analyzed by using one-way ANOVA test [P<0.05]. GLUT4 protein expression and glycogen levels in gastrocnemius muscle in diabetic+ aerobic training+ extract group were significantly higher than in the diabetic control group [P values 0.001, 0.02 respectively], whereas these variables in the aerobic training and the Pistacia athlantica extract perse groups did not change compared to the diabetic control group. It seems that Pistacia athlantica extract along with specific exercises, compared to utilization of each of strategies perse, are more effective in increasing glucose transporter proteins and possibly improving insulin function

RESUMO

Aos frutos e óleos essenciais da aroeira da praia (Schinus terebinthifolius) atribui-se atividade antimicrobiana sobre bactérias gram positivas além de ação anti-inflamatória. O óleo essencial da aroeira é utilizado no tratamento de micoses, sendo a sua atividade antifúngica atribuída à alta concentração de monoterpenos. Este estudo teve como objetivo determinar o melhor rendimento de destilação de óleo essencial de sementes e folhas da aroeira e os componentes químicos do óleo essencial nos diversos períodos de destilação. Cem gramas de cada material foram destilados em aparato de Clevenger durante 2,5h, 4,0h, 5,5h e 7,0h. O material destilado foi analisado por cromatografia a gás acoplada a espectrofotômetro de massas, onde foi obtido o perfil cromatográfico do material. As sementes de aroeira apresentaram maiores quantidades de óleo essencial, quando comparadas com as folhas em todos os períodos de destilação. O óleo essencial de aroeira mostrou perfil volátil formado principalmente por mono e sesquiterpenos.


The fruits and essential oils of Brazilian pepper (Schinus terebinthifolius) have antimicrobial activity against gram-positive bacteria, as well as anti-inflammatory action. The essential oil of Brazilian pepper is used to treat fungal infections, and its antifungal activity is attributed to the high concentration of monoterpenes. This study aimed to determine the best yield of distillation of the essential oil of seeds and leaves of Brazilian pepper and the chemical components of the essential oil in different periods of distillation. One hundred grams of each material were distilled in Clevenger apparatus for 2.5 h, 4.0 h, 5.5 h and 7.0 h.

RESUMO

Chios Gum Mastic (CGM) is a natural resin extracted from the leaves of Pistacia lentiscus, a plant endemic to the Greek island of Chios. It has been used by traditional healers, and it has antibacterial, antifungal properties, and therapeutic benefits for the skin. The CGM reduces the formation of dental plaque and bacterial growth in oral saliva, and recent studies have demonstrated the role of antioxidant activity of CGM. Although CGM has been widely investigated, its protective effect against oxidative-damage to keratinocytes, as well as the relationship between CGM and autophagy, has not been investigated. The aim of this study was to assess the protective effect of CGM against H2O2-induced oxidative stress and to evaluate the autophagic features induced by CGM in human keratinocytes. The pretreatment with CGM significantly reduced apoptosis in H2O2-exposed HaCaT cells. It promoted the degradation of caspase-3, caspase-8, and caspase-9; and it induced the formation of the processed PARP. The treatment with CGM caused an increase in vesicle formation compared to control group. The level of p62 was reduced and the conversion of LC3-I to LC3-II was increased in CGM treated HaCaT cells. Also, the treatment with CGM increased cleavage of ATG5-ATG12 complex. In summary, CGM helps the cells to survive under stressful conditions by preventing apoptosis and enhancing autophagy. Besides, the present investigation provides evidence to support the antioxidant potential of CGM in vitro and opens up a new horizon for future experiments.

RESUMO

The present research investigation was aimed at the evaluation of antioxidant activities of methanolic [70%] extracts of whole plant of Pentanema vestitum and fruits of Pistacia integerrima, Withiana somniferra and Withiana coagulans on scavenging of 2, 2-diphenyl-2-picrylhydrazyl [DPPH] free radical. The rank of order of free antioxidant activity of the selected plants was; P. integerrima > P. vestitum > W. somniferra > W. coagulans as compared to standard Ascorbic acid. P. integerrima showed significantly higher activity at all concentrations as compared to Ascorbic acid at P<0.05. The percent inhibition caused by P. integerrima at lowest concentration [40 ppm] was 68.16 +/- 0.5 and that of Ascorbic acid was 62.00 +/- 0.5. The IC[50] value of P. integerrima was 5.75ppm as compared to ascorbic acid having 15.09 ppm. The percent inhibition at all concentrations caused by P. vestitum was not significantly different from Ascorbic acid at P<0.05. The IC[50] value of P. vestitum was 13.00ppm and that of Ascorbic acid was 15.09 ppm. The percent inhibitions caused by W. somniferra [IC[50]=46.85 ppm] and W. coagulans [IC[50]=84.40 ppm] were most significantly lower than Ascorbic acid at P<0.05. It is inferred from the current study that the methanolic [70%] extracts of the P. integerrima and P. vestitum could be used in preparation of potent antioxidant drugs

RESUMO

Eleven types of nuts and seeds were analyzed to determine their energy (326-733 mg), moisture (1.6-18.3 mg), carbohydrate (8.8-70.9 mg), protein (4.9-30.5 mg), lipid (2.5-69.8 mg), and ash (1.2-5.5 mg) contents per 100 g of sample. Energy content was highest in pine nuts (733 mg/100 g), carbohydrate level was highest in dried figs (70.9 mg/100 g) and protein was highest in peanuts (30.5 mg/100 g). The amino acid compositions of nuts and seeds were characterized by the dominance of hydrophobic (range = 1,348.6-10,284.6 mg), hydrophilic (range = 341.1-3,244.3 mg), acidic (range = 956.1-8,426.5 mg), and basic (range = 408.6-4,738.5 mg) amino acids. Monounsaturated fatty acids (MUFA) were highest in macadamia nuts (81.3%), whereas polyunsaturated fatty acids (PUFA) were highest in the walnuts (76.7%). Macadamia nuts did not contain any vitamin E, whereas sunflower seeds contained the highest level (60.3 mg/kg). Iron (Fe) content was highest in pumpkin seeds (95.85 +/- 33.01 ppm), zinc (Zn) content was highest in pistachios (67.24 +/- 30.25 ppm), copper (Cu) content was greatest in walnuts (25.45 +/- 21.51 ppm), and lead (Pb) content was greatest in wheat nuts (25.49 +/- 4.64 ppm), significantly (P < 0.05). In conclusion, current commercial nuts and seeds have no safety concerns, although further analysis of Pb contents is necessary to ensure safety.

RESUMO

In this study, we investigated the binding ability of Saccharomayces cerevisiae to aflatoxin in pistachio nuts. The obtained results indicate that S. cerevisiae has an aflatoxin surface binding ability of 40 percent and 70 percent (with initial aflatoxin concentrations of 10 and 20 ppb) in the exponential phase. Acid treatments increase this ability to approximately 60 percent and 73 percent for the two concentrations of aflatoxin, respectively. Heat treatments also enhance surface binding to 55 percent and 75 percent, respectively. Binding appears to be a physical phenomenon that saturates within the first 2-3 hours of the process. The obtained results indicate that yeast immobilization for toxin reduction on aflatoxin-contaminated pistachios had no effect on qualitative characteristics, such as color, texture, and peroxide value. Yeast cells, viable or nonviable, are effective for aflatoxin binding, and this property could lead to a promising solution to aflatoxin contamination in high-risk foods.

RESUMO

Chios gum mastic (CGM) is a resinous exudate obtained from the stem and the main leaves of Pistacia lenticulus tree native to Mediterranean areas. Recently it reported that CGM induce apoptosis in a few cancer cells in vitro. Bile acids and their synthetic derivatives induced apoptosis in various kinds of cancer cells and anticancer effects. It has been reported that the synthetic chenodeoxycholic acid (CDCA) derivatives showed apoptosis-inducing activity on various cancer cells in vitro. This study was undertaken to investigate the synergistic apoptotic effect of cotreatment with a natural product, CGM and a CDCA derivative, HS-1200 on G361 human melanoma cells. To investigate whether the co-treatment of CGM and HS-1200 compared with each single treatment efficiently reduced the viability of G361 cells, MTT assay was conducted. To investigate augmentation of apoptosis in G631 cells co-treated with CGM and HS-1200, DNA electrophoresis, Hoechst staining, proteasome activity assay, flow cytometry, Westen blot analyses, immunofluorescent staining and confocal microscopy were performed. In this study, G361 cells co-treated with CGM and HS-1200 showed several lines of apoptotic manifestation such as nuclear condensations, DNA fragmentation, the reduction of MMP and proteasome activity, the decrease of DNA content, the release of cytochrome c into cytosol, the translocation of AIF and DFF40 (CAD) onto nuclei, activation of caspase-9, caspase-3, PARP and DFF45 (ICAD), and up-regulation of Bax whereas each single treated G361 cells did not. Although the single treatment of 40 micro/mL CGM or 25 micro HS-1200 for 24 hrs did not induce apoptosis, the co-treatment of them induced prominently apoptosis. Therefore, combination therapy of CGM and HS-1200 could be considered, in the future, as an alternative therapeutic strategy for human melanoma.

RESUMO

Antimicrobial packaging is a form of active packaging that could extend the shelf-life of foods and provides microbial safety for consumers. In order to control undesirable microorganisms on food surfaces, volatile and non-volatile antimicrobial agents can be incorporated into polymers. Incorporation of essential oils and other antifungal agents in edible films composition is an antimicrobial packaging that able to inhibit fungal growth on the pistachio and aflatoxins production. The antifungal activity of Avishan-e Shirazi [Zataria multifora] extracts against Aspergillus flavus in whey protein concentrate-based coating on pistachio kernels was investigated. The antifungal effect of Avishan-e Shirazi extracts was investigated in culture media by direct method [cup plate method] and application of whey protein concentrate [WPC] films as discs [disc deffusion method] incorporated with different concentrations of extracts. In order to evaluate the antifungal effect of extract in pistachio kernels coated with different concentrations of extract inoculated with a culture media discs contain 9-day-old growing A. flavus colony and the growth rate of inoculated discs were measured during 1 week. In experimental condition, minimal inhibition concentration was achieved by 90ppm of ahcoholic extract [30 percent concentration]. The results also showed that WPC coating incorporated with 2500ppm of Zataria multiflora extracts on pistachio kernels inhibited A. flavus growth totally. Regarding to application of importance of contamination with toxigenic fungi in pistachio kernel is suggested the application of Avishan-e Shirazi extract incorporated in edible coatings for toxigenic fungi growth and toxin production in foods

RESUMO

Resistance to antibacterial agents and sensivity reaction to such chemical compounds are the main reasons for investigators to develop new antibiotics from herbal sources. Antimicrobial effects of Metanolic extract of 12 herbal species Pistacia atlantica, Amygdalus scoparia, Cuscuta epthymum, Ephedra procera, Salsola boryosm, Sameraria armena, Scabiosa olivier, Scorzonera tortuosissima, Lepyrodielis holosteoidea, Vaccaria pyramidata, Sonchus oleraceam and Silene conoidema on 6 bacterial strains Staphylococcus aureas, Staphylococcus epidermidis, Echerichia colt, Kelebsiella pneumonia, Pseudomonas aeroginos and Bacillus subtilis were, separately, studied using Cylinder-plate method. In this laboratory study, methanolic extracts of herbal strains were prepared by maceration and after concentrating the extracts were dried. Then the concentrations of 50, 25, 12.5, 6.25 and 3.125 mg/ml of the extracts were prepared using 1:1 solution of DMSO/methanol. The standard bacteria with certain concentration [0.5 MacFarland] were inoculated on to the Muller-Hinton agar medium. Prepared extracts were dropped into cylinders and 18-24 hours after incubation and penetration of extract into the culture medium, the antibacterial effects and growth inhibitory zone [mm] were measure and values were expressed as [Mean +/- SEM]. The least and the most amount of effective concentration were 3.125 mg/ml and 50 mg/ml, respectively. The most inhibitory diameter belonged to methanolic extract of Amygdalus scoparia on Staphylococcus epidermidis which was equal to 19 +/- 0.3mm. Metanolic extracts of herbal species of Pistacia atlantica, Amygdalus scoparia and Ephedra procera had the most antibacterial effects compared to gentamicin as positive control. Regarding the side effects of the synthetic drugs and also benefits of such herbal extracts, extracts of these herbs as antibacterial agents after further investigations seems to be useful

RESUMO

The essential oil from the gum of Pistacia atlantica Desf. grown in Algeria was obtained by the hydrodistillation method; and its antimicrobial activities against the growth of clinical isolates of Staphylococcus aureus; Escherichia coli and Streptococcus pyogenes were evaluated using three different methods; agar disc diffusion and dilution broth methods and minimum inhibitory concentration (MIC) which was subsequently; determined. The results of the study revealed that essential oil resin of P. atlantica has antimicrobial activity against gram-positive and -negative bacteria which are resistant to commonly used antimicrobial agents; and they were considerably dependent on concentration

RESUMO

Chios gum mastic (CGM) is a resinous exudate obtained from the stem and the main leaves of Pistacia lenticulus tree native to Mediterranean areas. Recently, it was reported that CGM induced apoptosis in a few cancer cells in vitro. Since recent studies indicated the synergistic interactions between the apoptotic stimulus and a proteasome inhibitor, the ubiquintin-proteasome pathway has become an attractive target in cancer therapy. And to date, there has been no report of the synergistic apoptotic effect between CGM and a proteasome inhibitor to become an attractive target in cancer therapy. Therefore, this study was undertaken to investigate the synergistic apoptotic effect of co-treatment with a natural product, CGM, and a proteasome inhibitor, lactacystin, on human osteosarcoma (HOS) cells. To investigate whether the co-treatment of CGM and lactacystin compared with each single treatment efficiently induced apoptosis on HOS cells, MTT assay, DNA electrophoresis, Hoechst staining, DNA hypoploidy assay, Westen blot analysis, immunofluorescent staining, proteasome activity and mitochondrial membrane potential (MMP) change were performed. In this study, HOS cells co-treated with CGM and lactacystin showed several lines of apoptotic manifestation such as nuclear condensation, DNA fragmentation, the reduction of MMP and proteasome activity, the decrease of DNA content, the release of cytochrome c into cytosol, the translocation of AIF and DFF40 (CAD) onto nuclei, and activation of caspase-7, caspase-3, PARP and DFF45 (ICAD) whereas each single treated HOS cells hardly showed. We presented data indicating that the co-treatment of CGM and lactacystin induced potentially apoptosis whereas each single treatment did slightly. Moreover, the co-treatment of CGM and lactacystin potentiated the inhibition of proteasome activity. Therefore, our data provide the possibility that combination therapy of CGM and lactacystin could be considered as a novel therapeutic strategy for human osteosarcoma.
