Résumé

Mosquito-borne diseases result in the loss of life and economy, primarily in subtropical and tropical countries, and the emerging resistance to insecticides is increasing this threat. Botanical insecticides are promising substitutes for synthetic insecticides. This study evaluated the larvicidal and growth index of Culex pipiens of four solvent extracts of Terminalia chebula, Aloe perryi, and Peganum harmala against Cx. pipiens. None of the 12 extracts exhibited larvicidal potential against third instars except the ethyl acetate extract of P. harmala. After 24 h of exposure, the LC50 value was 314.88 ppm, and the LC90 value was 464.19 ppm. At 320 ppm, the hatchability was 25.83%, and it resulted in 100% mortality. In addition, the eggs treated with the EtOAc extract of P. Harmala exhibited a long larval period compared with the control. The larval period continued for 12 days, and the pupal period took three days in the treatment groups. The growth index data also exhibited a decrease (0.00­7.53) in the treated groups compare with 8.5 in the control. The transformation of eggs into adults decreased with increasing concentrations. This paper is the first report on the development and growth index of Cx. pipiens potential using P. harmala seeds.

Este estudo avaliou o índice larvicida e de crescimento de Culex pipiens de quatro extratos solventes de Terminalia chebula, Aloe perryi e Peganum harmala contra Cx. pipiens. Nenhum dos 12 extratos exibiu potencial larvicida contra o terceiro ínstar, exceto o extrato de acetato de etila de P. harmala. Após 24 horas de exposição, o valor LC50 era 314,88 ppm e o valor LC90 era 464,19 ppm. A 320 ppm, a eclodibilidade foi de 25,83% e resultou em 100% de mortalidade. Além disso, os ovos tratados com o extrato de EtOAc de P. harmala exibiram um longo período larval em comparação com o controle. O período larval continuou por 12 dias, e o período pupal durou três dias nos grupos de tratamento. Os dados do índice de crescimento também exibiram uma diminuição (0,00-7,53) nos grupos tratados em comparação com 8,5 no controle. A transformação de ovos em adultos diminuiu com o aumento das concentrações. Este artigo é o primeiro relatório sobre o índice de desenvolvimento e crescimento de Cx. potencial de pipiens usando sementes de P. harmala.

Résumé

The present study was carried out to record and evaluate the effect of Rosa brunonii, Calligonum polygonoides, Sueda fruticosa and Pegnum harmala L., extracts on brine shrimp collected during March-June 2013 from different regions of District Bannu. These four plants were medicinal xerophytes and widely distributed throughout Pakistan. Rosa brunonii is commonly used as a hedge plant for gardening. Calligonum polygonoides and Sueda fruticosa are locally used as a fuel, while Pegnum harmala [L.] is the most important multipurpose medicinal xeric plant, which is used for various purposes. All these selected medicinal xerophytes have inhibitory effect on bacterial growth. In this study the effect of different concentration [10-70 microg/ml] were tested on brine shrimp. The results showed that maximum cytotoxic activities were observed in Rosa brunonii [100.0+/-0.4], Calligonum polygonoides [100.0+/-0.2] and Pegnum harmala [L.] [90.0+/-5.2] while Sueda fruticosa [50.0+/-7.1] has less cytotoxic property. These activities are may be due to the presence of bioactive constituents

Résumé

The optic-fiber sensor technology combined with near-infrared diffuse reflection spectroscopy was applied to directly analyze Peganum harmala and identify different origin of P. harmala on the basis of principal component analysis, clustering analysis, SIMCA method, which resulted in the establishment of a new method to rapidly and nondestructively identify the origin of P. harmala. The original full wavelength spectrum for principal component analysis and the score of first two principal components can distinguish four origins of P. harmala basically. In the wavelength range of 866-2,507 nm, MSC as pretreatment method to establish the best model of clustering analysis to forecast the samples with the accuracy of 91.67%, can distinguish the four origins of P. harmala while in the wavelength of 1,085-2,507 nm, normalization method as pretreatment methods to establish a best model of SIMCA to forecast the sample, all the samples except for the changji sample have been identified with a total recognition rate of 97.22%. The results show that using near infrared diffuse reflectance spectroscopy combined with SIMCA is the best method that can be effectively used to identify the P. harmala.

Résumé

Bacterial resistance to antibiotics is a main problem in the treatment of infectious diseases. Thus, searching for alternative drug is essential in Iran and particularly Chaharmahal va bakhtiari province. People use medicinal smokes such as donkey dung and Peganum harmala seed smokes for treatment of infectious diseases. Therefore, this study was aimed to evaluate the antimicrobial property of donkey dung and Peganum harmala seed smokes on Staphylococcus aureus and Pseudomonas aeroginosa. In this interventional and laboratory study, groups of Peganum harmala seed smoke and donkey dung were considered as case groups and antibiotic disks as positive control group. Pseudomonas aeroginosa and Staphylococcus aureus were cultured in suitable medium [Blood Agar, EMB and Mueller-Hinton agar]. Antibiogram blank disks were fumigated separately with Peganum harmala seed and female donkey dung smoke then placed on microbial plate with sterile methods. Following 48 hours incubation at 37°C, the zone of growth inhibition evaluated by measuring the zone around the disks. Fumigation process was done in special chest that designed for this research. We repeated fumigation each 20 minutes for 24 times. Data about measuring the zone of growth inhibition were analyzed by using and mean statistic exam. Staphylococcus aureus was sensitive to Peganum harmala seed, and fdonkey dung smokes and Pseudomonas aeroginosa was sensitive to female donkey dung smoke. Staphylococcus aureus was resistant to cloxacilllin and Pseudomonas aeroginosa was sensitive only to erythromycin and ciprofloxacin. The increasing time of fumigation in sensitive cases enhanced antimicrobial effects and the zone of growth inhibition. Antimicrobial effects of donkey dung smokes on resistance pathogens such as Pseudomonas aeroginosa, Staphylococcus aureus revealed the necessity of performing expanded research about composition and property of this smoke

Résumé

Cutaneous leishmaniasis is an important health problem caused by Leishmania spp. As there is no vaccine, drug treatment is the only way to tackle leishmaniasis. In the present study, inhibitory and killing effects of Peganum harmala and Alkana tinctoria extracts on amastigotes and promastigotes forms of Leishmania were evaluated in-vitro. The seeds of Peganum harmala, Stems and roots of Alkanna tictoria were collected and crude extraction carried out. In this experimental study, Leishmania major promastigotes were cultured in RPMI-1640 with 10% FBS at 22-26°C, and infected macrophages with amastigotes were cultured in RPMI-1640 with 10% FBS at 37°C in 5% CO2. Then the extracts of each plant were added to cultivated parasites and incubated for 3 days. Promastigote and amastigote assay was carried out using counting assay based on growth inhibition. The results indicated that both extractions can inhibit the growth of promastigotes, and in concentrations of 40 micro g/ml of P. harmala, 200 micro g/ml of A. tincturia, and 20 micro g/ml of equal combination of P. hamala and A. tincturia are Inhibitory Concentration [IC50] for parasites growth. By adding these concentrations of the extracts to the infected macrophages in the culture, their effects were separately evaluated. The mean of amastigotes number in macrophages in the culture with P. harmala, A. ticturia, combination and control groups were 0.7, 0.7, 0.6, 2.3 amastigotes per macrophage, respectively. By this method, inhibition of intracellular and extracellular growth of L. major was demonstrated suggesting that, plant drugs with efficacy and safe products can be applied as new treatment for cutaneous leishmaniasis

<p><b>OBJECTIVE</b>To investigate the protective effect of 17beta-estradiol (E2), peganum harmala extract (PHE) administration and calorie restriction (CR) treatment (60%) on oxidative stress and hepato-toxicity in aged rats.</p><p><b>METHODS</b>Eighteen months old animals that were treated at the age of 12 months were divided into 4 groups: normal control group with free access to food, E2 treatment group, PHE treatment group and CR treatment group of the food given to control group. Six male rats at the age of 4 months were used as a reference group.</p><p><b>RESULTS</b>Aging significantly decreased superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX), and increased lactate deshydrogenase (LDH), gamma-glytamyl transferase (GGT), phosphatase alkalines (PAL), aspartate and lactate transaminase (AST and ALT) activities in the liver. Aging also induced an increased lipid peroxidation level, histological changes and a decreased E2 level. However, treatment with E2, PHE, and CR increased 17beta-estradiol, and decreased hepatic dysfunction parameters and lipid peroxidation as well as histological changes in the liver of aged rats.</p><p><b>CONCLUSION</b>The antioxidant and hepatoprotective activity of PHE and CR is possibly attributed to its ability to increase E2 level, which as an antioxidant, acts as a scavenger of ROS.

Résumé

Cancers and hepatoprotective prevention using traditional medicines have attracted increasing interest. The aim of our study was to characterize the putative protective effects of ethanol and chloroform extracts of Peganum harmala on thiourea-induced diseases in adult male rat. We seek to determine the effects of these plant extracts on body weight, thyroid and endocrine cancer parameters. In addition the putative hepatoprotective effect was checked by the determination of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities and the bilirubin level in the blood. Our data show that ethanol and chloroform extracts of Peganum harmala protected the animal against the carcinogenic effects induced by thiourea since neuron-specific enolase (NSE) and thyroglobulin (TG) levels were back to the normal range. In addition, the observed-hepatocytotoxicity after thiourea treatment was greatly reduced (AST and ALT activities were respectively 270 IU/l and 60 IU/l and in the same order of magnitude as in the untreated rats) as well as the bilirubin levels (6 micromol/l) especially for animals receiving the choroform preparation. Therefore we may suggest that extracts of Peganum harmala are efficient to reduce the toxicity induced by thiourea in male rat as far as the above parameters are concerned.

Résumé

<p><b>AIM</b>To investigate the effects of 17beta-estradiol (E2), Peganum harmala extract (PHE) and caloric restriction (CR) on various testis parameters during aging.</p><p><b>METHODS</b>Twelve month-old male rats were treated for 6 months with either E2 or PHE, or submitted to CR (40%).</p><p><b>RESULTS</b>Our results show that estrogens and CR are able to protect the male gonad by preventing the decrease of testosterone and E2 levels as well as the decrease of aromatase and estrogen receptor gene expressions. Indeed, E2, PHE and CR treatments induced an increase in the superoxide dismutase activities and decreased the activity of testicular enzymes: gamma-glutamyl transferase, alkaline phosphatase, lactate deshydrogenase as well as the aspartate and lactate transaminases in aged animals. In addition, the testicular catalase and gluthatione peroxidase activities were enhanced in E2, PHE and CR-treated rats compared to untreated animals at 18 months of age. Moreover, the positive effects of estradiol, PHE and CR were further supported by a lower level of lipid peroxidation. Recovery of spermatogenesis was recorded in treated rats.</p><p><b>CONCLUSION</b>Besides a low caloric diet which is beneficial for spermatogenesis, a protective antioxydant role of estrogens is suggested. Estrogens delay testicular cell damage, which leads to functional senescence and, therefore, estrogens are helpful in protecting the reproductive functions from the adverse effects exerted by reactive oxygen species (ROS) produced in large quantities in the aged testis.</p>

Résumé

It had been indentified by histological, histochemical and morphometrical studies that peganum harmala is a mammogenic herb and borage officinalis is a lactogenic one. To complete our investigation about these two herbs, we performed electron microscopical study. Rats were grouped according to their physiological status into three groups. Each group was subdivided into three subgroups: one control and two experimental. The two experimental groups were treated daily; the 1[st] one with an aqueous extract of peganum harmala seeds and the 2[nd] with an aqueous extract of borage officinalis flowers. After two weeks of treatment, mammary glands were employed for electron microscopical study. In virgin rats, the epithelial and myoepithelial cells were partially differentiated when harmal was given and completely differentiated when borage was given. In pregnant rats, harmal and borage optimize mammary parenchymal growth and induce lactation when these herbs were given. In lactating rats, these herbs exhibited a picture similar to control lactating group but the budding of lipid droplets and the swelling of secretary vesicles were markedly increased. Both harmal and borage stimulate the release of prolactin and induce galactogenesis during pregnancy and promote it during lactation

Theileria annulata, a protozoan parasite of cattle and domestic buffaloes, is transmitted by ticks of the genus Hyalomma, and causes a disease named Mediterranean or tropical theileriosis. In this research 50 cattle naturally infected with Theileria annulata were treated with the extract of the plant Peganum harmala. The treatment was continued for 5 days, the dose of the extract being 5 mg/kg per day. After the treatment, 39 cattle responded to the treatment and recovered, but 11 did not respond to the treatment and died. The recovery rate of animals treated with the extract of the plant Peganum harmala was 78%.

Résumé

In the present work, the seeds of the medicinal plant Peganum harmala L.were extracted by both water and methanol to evaluate their in vitro anthelmintic activity against fasciola gigantica. RPMI 1640 medium was used for maintenance of the parasite in culture. The highest concentrations of the seeds aqueous extract of Peganum harmala of 15000 and 5000 ppm gave 100% mortality one hour after the parasite exposure to the extract. The lower concentrations had revealed no effect against the parasite, except the concentration 1000 ppm which gave 25% mortality in the second hour and reached 100% mortality after the 6th. hour of exposure. The seed methanolic extract of Peganum harmala was significantly [P<0.001] potent and revealed mortality at both 1000 and 500 ppm as follows: 17, 17, 83, 100 and 100% and 0, 0, 17, 66, 83% respectively, at the exposure times of 1, 2, 3, 6 and 24 hours

Résumé

Many aldehydes are important components of natural flavours. They are used in food, cosmetic, and biomedical industries in large amounts. Plant cells or microorganisms carry out their production by biotransformation, which is one of the biotechnological methods that allow them to be defined as 'natural'. Cell cultures of Silybum marianum and Peganum harmala have been studied with a view to investigate their abilities to produce flavonolignans and beta-carboline alkaloids respectively. However, we have isolated S. marianum and P. harmala culture strain, which are able to metabolise several aromatic aldehydes. Ten culture strains derived from S. marianum and P. harmala were examined for their ability to biotransform exogenous aromatic aldehyde compounds, including benzaldehyde, 2-methoxybenzaldehyde, 4-methoxybenzaldehyde, cinnamaldehyde and 3-methoxy, 4-hydroxy benzaldehyde. Callus cultures of Silybum marianum and Peganum harmala were established from seedlings, and healthy suspensions were grown using the Murashige and Skoog medium. Exogenous aromatic aldehydes were fed to S. marianum and P. harmala cell suspension cultures. Biotransformation reactions were detected over 24 h of incubation. The cultures then extracted with dichloromethane and extracts subjected to GC and GC-MS analysis. The S. marianum cultured cells in this study exhibit greater selectivity in the reduction of aromatic aldehydes than P. harmala cultured cells. The ability of cultured plant cells to biotransform substrate appears to be dependent on the culture strains as well as the nature and position of the substituent on the aromatic ring
