preferably from 0.02 to 30% by weight. In this case, the ascorbic acid-2-phosphate or a salt thereof and the zinc salt compound may be mixed at any ratio, however, in view of the effect, the molar ratio between the ascorbic acid-2-phosphate and the zinc salt compound is preferably 1...
pregnancyIn Masanga, Sierra Leone, a multigravid woman presented with a urine pregnancy test negative molar pregnancy. This can be explained by the 'hook-effect'. In resource-poor settings where quantitative serum hCG cannot be determined, it is of paramount importance to remain vigilant of the...
