Purpose: To develop orally disintegrating tablets of ondansetron HCl using natural Superdisintegrants. Method: Tablets containing the drug were prepared by dry granulation method using different concentrations of superdisintegrants such as modified gum karaya, modified natural agar, crosscarmellose sodium and sodium starch glycollate. The formulations were evaluated for weight variation, hardne...

Pantoprazole is a potent and selective proton pump inhibitor. It is an effective agent in the treatment of Peptic ulcers, Gastro-oesophageal reflux disease (GERD), Oesophagitis, Zollinger-Ellison syndrome and other GI hypersecretory disorders. It provides rapid symptoms relief up to 85-90% of Ulcer patients within 1 hour of treatment. It has mediocre bioavailability of 50% and poor aqueous solu...

1. Micrococcus denitrificans utilized glycollate as sole carbon source for aerobic growth. Glyoxylate was utilized less well, and though glycine alone did not support growth it enhanced growth on glyoxylate. 2. During growth on glycollate, (14)C was incorporated from [2-(14)C]glycollate into glycine and thence into aspartate, malate and glutamate. No phosphoglycerate was labelled at the earlies...

Both glyoxylate reductase (NADP+) and glycollate dehydrogenase were located exclusively in mitochondria in Euglena gracilis and constitute the glycollate--glyoxylate shuttle, whose existence in higher plants was thought doubtful, owing to different subcellular locations of the two enzymes. Disrupted Euglena mitochondria showed a glycollate-dependent NADPH oxidation, indicating actual operation ...

In a previous paper we have shown that disalicyli­ denepropanediamine (DSPD), an inhibitor of photo­ synthetic reduction of ferredoxin1, stimulates re ­ labelling of glycollic acid in algal cells2. Further ex­ periments led to the observation that also the excretion of 14C-labelled glycollate is enhanced by DSPD 3. We supposed that the increase of glycollate formation and excretion by DSPD is d...

1. The conditions under which peroxisomal preparations from leaves of spinach beet and spinach catalyse the release of (14)CO(2) from [1-(14)C]glycollate and [1-(14)C]glyoxylate were investigated. 2. At pH8, (14)CO(2) production from [1-(14)C]glyoxylate was accompanied by equivalent quantities of formate. The accumulation of oxalate and the effects of various reagents, especially catalase inhib...

1. Lowering of the concentration of carbon dioxide in air available to phototrophically growing Euglena cultures from 5% to the normal value (0.03%) resulted in an increased specific activity of glycollate oxidoreductase. 2. The effects of chloramphenicol and cycloheximide suggested that this increase in activity was due to enzyme synthesis de novo on cytoplasmic ribosomes. 3. The K(m) for glyc...

1. Exogenous glycollate was rapidly metabolized in both the light and the dark by photoautotrophically grown Chlorella pyrenoidosa. 2. The incorporation of (14)C from [1-(14)C]glycollate by these cells was inhibited by the tricarboxylic acid-cycle inhibitors monofluoroacetate, diethylmalonate and arsenite, and also by alpha-hydroxypyrid-2-ylmethanesulphonate and isonicotinylhydrazine. 3. Short-...

The traditional use of sodium chloride (NaCl) fulfils various important rheological, technological and sensory properties while manufacturing of baked goods. However, using NaCl in the production of food has been controversially discussed since a high intake of sodium is discussed to be associated with hypertension. Retrogradation of starch in bread crumb is defined for changes that take place ...
