Cellular neutral lipid content of Paramecium primaurelia was measured during culture and clonal life using nile red (9-diethylamino-5H-benzo[alpha] phenoxazine-5-one), a dye utilized for lipid analysis in both mammalian cells and in ciliated protozoa. Lipid droplets in P. primaurelia are concentrated in the anterior pole of the cell; their number is maximum in early log phase cells and decrease...

1. Specific precipitates resulting from the interaction of the homologous capsular polysaccharide and Type I antipneumococcus horse and rabbit sera have been analyzed by gasometric micro methods for total nitrogen, lipid nitrogen, and lipid carbon. 2. Lipid may, under certain conditions, form as much as 51 per cent or as little as 4 per cent by weight of specific precipitates. 3. The total lipi...

       This study was designed to explore the protective effects of ascorbic acid and water extract of Spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates....
