Spirulina platensis trichomes grown in Zarrouks medium having total Na+ concentration as 0.14 M when transferred to fresh Zarrouks medium containing enhanced level of Na+ ions equal to 0.86 M showed 30% more accumulation of Na+ intracellularly as compared to the control. An inhibition of photosystem II activity to almost 66% was observed. Also due to this exposure to high Na+, the room temperat...

BACKGROUND Current breath tests for measurement of gastric emptying of solids are expensive, possibly inaccurate, and require cumbersome calculations. AIMS We wished to validate a simplified solid gastric emptying test using a [(13)C]Spirulina platensis breath test for accurate results relative to scintigraphy. SUBJECTS Thirty healthy volunteers. METHODS We measured gastric emptying of eg...
