The quantitative determination of usnic acid (UA), perlatolic acid (PA), and atranorin (AT) in Alaska lichens by micellar electrokinetic chromatography (MEKC) is reported. The background electrolyte (BGE) included sodium docecyl sulfate (SDS), and beta-cyclodextrin (beta-CD) in a high-pH borate buffer. The presence of beta-CD in the buffer significantly(More)
In the present study we examined light-microscopically the nuclei of 16 hearts (7 normal hearts, 7 hearts with hypertrophy and 2 hearts with atrophy) for the size, number and morphology of their nucleoli. The size of the nucleoli, defined as the total area of all nucleoli per nucleus, was an early and sensitive indication of a beginning hypertrophy of the(More)
A cloned line of myeloid leukemic cells can be induced by the alkylating agent nitrosoguanidine for two macrophage- and granulocyte-inducing (MGI) activities. One activity, MGI-I, induced the formation of macrophage and granulocyte colonies from normal myeloblasts. Another activity, MGI-2, induced differentiation of MGI+D+ myeloid leukemic cells to(More)
