neutral red supravital staining for cellular elements in the semen.human seminal fluid besides spermatozoa often contains other cellular elements. a supravital staining method designed to differentiate the above mentioned cellular elements was described. amongst the spermatogenic cells only spermatocytes were stained with neutral red. they displayed two peculiar structures designated as "y" granules and "enigmatic body". neutral red was absorbed by the spermiophage cells and was concentrated by them in the form of cytoplasmic granules. in addition the coarse gr ...197875699
a parasitological study on the chacma baboon (papio ursinus) from the northern transvaal.baboons imported into rhodesia from the northern transvaal proved to be heavily infected with intestinal protozoa and helminths. in fact, six protozoan species, one cestode and eight nematode species were recorded. a new concept in "identification graphs" is included in the paper which allows one to read off directly the species of strongyle eggs being passed by baboons in southern africa based upon length and breadth measurements of the eggs. treatment of balantidium coli and nematode infection ...1978104037
[effects of mebendazole and cambendazole on enterohelminths in pigs].mebendazole, administered at a dose of 30 mg active substance per 1 kg of feed, was found to have 100% effectiveness on ascaris suum and cambendazole, administered at a dose of 1.5 g per 1 kg of liver weight, showed the same effectiveness in the control of ascaris suum and oesophagostomum dentatum. the effectiveness of both drugs on trichocephalus suis and strongyloides ransomi was low. mebendazole and cambendazole can be recommended for mass dehelminthization of pigs in affected stocks. helmint ...1979111399
