Effects of polysaccharide fractions isolated from Caltha palustris L. on the activity of phagocytic cells & humoral immune response in mice with collagen-induced arthritis: A comparison with methotrexate
BACKGROUND & OBJECTIVES The extracts from Caltha palustris L. have been shown to be beneficial for treating arthritis and rheumatism. In this study, the immunomodulatory effects of polysaccharide fractions B and C of C. palustris extracts were studied, using the collagen-induced arthritis (CIA) mouse arthritis experimental model. The aim was to determine the activity of blood phagocytic cells a...
متن کاملIntraspecific variation in the magnitude and pattern of flooding-induced shoot elongation in Rumex palustris.
BACKGROUND AND AIMS Intraspecific variation in flooding tolerance is the basic pre-condition for adaptive flooding tolerance to evolve, and flooding-induced shoot elongation is an important trait that enables plants to survive shallow, prolonged flooding. Here an investigation was conducted to determine to what extent variation in flooding-induced leaf elongation exists among and within populat...
متن کاملUsing Rhodopseudomonas palustris PT
Biohydrogen production from synthesis gas (syngas) was investigated using a local bacterium isolated from anaerobic sludge of dairy wastewater. The isolated strain Rhodopseudomonas palustris PT was able to convert syngas to hydrogen through water shift gas (WGS) reaction. The aim of present study was to determine the optimum concentration of ferric citrate which avoids the cell growth inhibitio...
متن کاملPhylogeny and biogeography of Caltha (Ranunculaceae) based on chloroplast and nuclear DNA sequences.
The genus Caltha (Ranunculaceae) consists of 10 species of low-growing, perennial herbs distributed throughout the moist temperate and cold regions of both the Northern and Southern Hemispheres. Traditionally, the species have been divided into two sections: section Psychrophila in the Southern Hemisphere with diplophyllous leaves and section Caltha in the Northern Hemisphere with leaves lackin...
متن کاملPhytochrome in Embryos of Pinus palustris.
Phytochrome has been shown to be involved in the germination of seeds of a number of pine species as determined by the responses of these seeds to red and far-red irradiations (4, 7, 9). Nyman (7) found that even before imbibition, germination of Pinits silvestris seeds can be promoted by red irradiation. McLemore (5) found that germination of longleaf pine seed (P. palustris) can be repeatedly...
