Immature embryos of Cymbidium iridioides were successfully cultured on five different media with various supplements and maintained in three different light conditions. Within three week of culture, embryos formed nodular structures. Cultures under full light condition formed green protocorm-like bodies while, other light conditions failed to support optimum germination. Immature embryos of 10 ...

The intake of saccharin solutions for relatively long periods of time causes analgesia in rats, as measured in the hot-plate test, an experimental procedure involving supraspinal components. In order to investigate the effects of sweet substance intake on pain modulation using a different model, male albino Wistar rats weighing 180-200 g received either tap water or sucrose solutions (250 g/l) ...

the effects of sucrose and some regulators on freezing tolerance in chickpea studied. four weeks in vitro explants were cultured in three different ms media without growth regulators and with normal level of sucrose (30 gl-1) (a), without growth regulators and with reduced sucrose (10 gl-1) (b) and medium supplemented with lmg gl-1 bap and 0.1 mgi1 iba and with 30 gi-1sucrose (c) for two weeks....

The promoters of the three Arabidopsis nuclear genes encoding mitochondrial cytochrome c oxidase subunit 6b (AtCOX6b) have similar expression patterns, with preferential expression in anthers and meristems, and are induced by sucrose and etiolation. Additionally, induction of AtCOX6b-1 by GA(3) and AtCOX6b-3 by 6-benzylaminopurine was observed. Site II elements (TGGGCC/T) present in the three p...

I. Eighty weanling albino rats, five from each of sixteen litters were distributed between five dietary groups in sixteen randomized blocks. Each block was formed from within a litter and each animal in the block received a different diet. 2. The main features of the diets were: group I , 72% sucrose; group 2, 72% uncooked wheat starch; group 3, 72% roll-dried wheat starch; group 4, 3 6 % sucro...

Sucrose-rich diets have repeatedly been observed to have co-carcinogenic actions in colon and liver of rats and to increase the number of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) induced aberrant crypt foci in rat colon. To investigate a possible interaction between sucrose and IQ on the genotoxicity in rat liver and colon, we gave Big Blue rats a diet containing sucrose (0%, 3.45% or 13.4%...

Food resources are complementary for a forager if their contribution to fitness is higher when consumed together than when consumed independently, e.g. ingesting one may reduce the toxic effects of another. The concentration of potentially toxic ethanol, [EtOH], in fleshy fruit increases during ripening and affects food choices by Egyptian fruit bats, becoming deterrent at high concentrations (...

Studies show that Oryza sativa L. contains a structure named β-glucan with anti cancer properties. In the present study, a tissue culture for rice was carried out and β-glucan content was measured under various sugar and vitamin levels in basic MS medium. Seeds of Hashemi cultivar were cultured on MS medium. Two plant hormones, namely, 2,4-D (0, 1, 1.5, 2 and 3 mg/l) and kinetin (0,0.5, 1, and ...

OBJECTIVE Iron therapy may reinforce intestinal inflammation by catalysing production of reactive oxygen species. The effects of oral ferrous fumarate and intravenous iron sucrose on clinical disease activity and plasma redox status were investigated in patients with inflammatory bowel disease (IBD). MATERIAL AND METHODS Nineteen patients with iron deficiency anaemia and Crohn's disease (11) ...

The synthesis of nanoparticulate α-Al 2 O 3 at 600 • C using a sucrose-based polymer dispersion technique was reported recently by Das et al. [1]. This is of interest, as γ-Al 2 O 3 is frequently an unwanted intermediate phase in the conversion of nanoparticulate amorphous alu-mina into nanoparticulate α-Al 2 O 3. γ-Al 2 O 3 has a relatively disordered structure, but usually requires temperatur...
