BACKGROUND & OBJECTIVES Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance underlines the importance of discovering new therapeutic products. The present study aims to investigate the in vitro antileishmanial activity and cytotoxicity of the ethanolic extract of Berberis vulgaris fruits and chloroform extract of Nigella sativa seeds against Leishmania...

This study aimed to investigate effects of varying doses of Nigella sativa seed powder or acetone extracts in diet on feed intake, mortality, serum lipid profiles and population of intestinal microflora of broilers. A total 168, day-old broiler chicks (Cobb 500) were ad-libitium manually prepared feeds supplemented with 0, 1.5, 2.5, 3.0% seed powder or 0, 0.2, 0.4% acetone extracts of N. sativa...

OBJECTIVES This study was conducted to determine whether the blood pressure-lowering effect of Nigella sativa might be mediated by its effects on nitric oxide, angiotensin-converting enzyme, heme oxygenase and oxidative stress markers. METHODS Twenty-four adult male Sprague-Dawley rats were divided equally into 4 groups. One group served as the control (group 1), whereas the other three group...

Nigella sativa (N. sativa) grows in various parts of the world, particularly in Iran. It has been traditionally used as a folk remedy to treat a number of diseases. The seeds of this plant contain moisture, proteins, carbohydrates, crude fiber, alkaloids, saponins, ash, fixed oils and essential oil. The major components of the essential oil are thymoquinone, p-cymene, trans-anethole, 2-methyl-5...

The objectives of this study were to provide data that can be used to predict exposure-based effects of RDX in aged soil on multiple endpoint organisms representing two trophic levels. These data can be used for defining criteria or reference values for environmental management and conducting specific risk assessment. Dose-response experiments formed the basis for the evaluation of toxic effect...

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Chromosomes of two diploid (2n=2x=16) subspecies of Medicago sativa, ssp. caerulea and ssp. falcata, their hybrid and tetraploid (2n=4x=32) cultivated alfalfa (M. sativa, ssp. sativa) were studied. Feulgen’s staining, Cand N-banding techniques and an image analysis system were used. The chromosomes of ssp. falcata hav...

to study the effect of salinity stress on seed germination and seedling growth of four medicinal plants, nigella sativa l., cannabis sativa l., trigonella foenum graecum and cynara scolymus l. an experiment was conducted in the botany laboratory of islamic azad university, birjand branch. a completely randomized design (crd) with 3 replications was used as separately for each species. treatment...

An epidemic of rice (Oryza sativa) blast occurred on cultivars Epagri 108 and 109 in the municipalities of Lagoa da Confusão and Duerê in the State of Tocantins, during the rice-growing season 199899. DNA fingerprinting and virulence phenotype analysis were utilized to determine the diversity of Pyricularia grisea isolates collected from these cultivars in one epidemic year. Rep-PCR analysis of...

BACKGROUND Since long high fat diet (HFD) is being blamed for causing fatty degeneration of liver and formation of atheromatous plaques. At present, no proper pharmacotherapy is available for both the conditions. In this study, different substances containing monounsaturated fatty acids were used to observe their protective effects in the HFD induced damage to liver and coronary vessels. OBJE...
