sodium Statistical structure study System time values Abstract: Methyl and propyl parahydroxybenzoate (MPHB, PPHB), phenylephrine hydrochloride (PE) and chlorphenamine maleate (CPM) are often combined as ...
An improved medium for the isolation of Cryptococcus neoformans from pigeon droppings36612
when methyl violet at 2 mg l-1 is added to the usual Guizotia abyssinica medium. In preliminary tests the medium has also proved useful for isolating C. neoformans from other sources Service: Mycology ...
Immunity and effect of clopidol/methyl benzoquate and robenidine before and after weaning on rabbit coccidiosis in the field.
months the anticoccidial effect of 200 ppm clopidol/methyl benzoquate and of 50 ppm robenidine, and the development of immunity against five different species of Eimeria were followed in a closed rabbit ...
GLC determination of pemoline in biological fluids153
