changes in ovarian activity during hepatocarcinogenesis by n-2-fluorenylacetamide: role of alpha-fetoprotein.	during chemical hepatocarcinogenesis by n-2-fluorenylacetamide, the hormonal status of female sprague dawley rats is largely modified. ovaries present a reduced activity which is evidenced by a decreased number of follicles and corpora lutea. the level of progesterone in n-2-fluorenylacetamide treated rats is low and agrees with the lack of corpora lutea. conversely, estradiol level remains normal. this fact may be explained by the presence of alpha-fetoprotein, a carcino-embryonic protein which ...	1979	94191

sample preparation variation and its effects on automated blood cell differential analysis.	uniform and reproducible sample preparation is an indispensable ingredient in automated instruments for cell analysis. differences in measured cell morphology resulting from nonuniform sample preparation are indistinguishable to the instrument from differences reflecting different cell types or functions. as a result, as sample preparation becomes more variable, subtle cell distinctions are first confused and then completely obscured. as part of the development of the abbott adc-500 differential ...	2000	94524
neutral protease activity in lymphocytes of lewis rats with acute experimental allergic encephalomyelitis.	lymphocytes from popliteal and inguinal lymph nodes of lewis rats with acute eae as a result of injection of lyophilized guinea pig myelin in freund's complete adjuvant exerted strong proteolytic activity at neutral ph toward myelin basic protein. after injection of myelin the level of proteolytic activity remained about the same as that in lymphocytes from freund's adjuvant-injected controls until about day 10 after injection, just before the onset of paralytic symptoms; then the proteolytic ac ...	1979	94652
a thymus-independent igg response against dextran b512 can be induced in c57bl but not in cba mice, even though both strains possess a vhdex gene.	cba and c57bl mice both possess a vhdex gene coding for antibodies against the alpha 1-6 epitope of dextran b512. after immunization with dextran, cba mice produce igm plaque-forming cells (pfc) only, which show regular cyclical fluctuations. the second pfc peak disappeared after injection of dextranase, indicating that it is antigen-dependent. the anti-dextran response in c57bl mice is characterized by only one igm peak, followed 1 day later by an igg peak that may exceed the igm response by a ...	2000	94695
hla types in corneal diseases.	evaluation of the results of hla typing of 187 patients grouped into herpetic keratitis (37), non-herpetic keratitis (43), keratoconus (42), endothelial dystrophy (23), stromal dystrophy (13), lues (5), and injuries (24), failed to show convincing deviations in any of the groups from a normal control series (2900 persons). yet, as for the herpes group, a rise in b5 must strongly be suspected. the data are presented and possible implications are discussed.	1979	94740

mechanism of binding of mouse interferon to controlled pore glass.	many proteins bind to controlled pore glass; they are either acid elutable or alkali elutable. mouse interferon is an acid-elutable protein. since poly(l-lysine) and, to some extent, poly(l-arginine) are also eluted from controlled pore glass under acidic conditions, one may postulate that mouse interferon binds to controlled pore glass via some of the protein's epsilon-amino groups (of lysine) and/or guanidinium groups (of arginine) and the beads' silanol (hydroxyl groups). the necessity of lys ...	1979	94835

prevention of the cortical reaction in fertilized sea urchin eggs by injection of calcium-chelating ligands.	eggs from the sea urchin, lytechinus pictus, were injected with either egta or edta, and were subsequently fertilized. egta prevented cortical vesicle discharge and formation of the fertilization membrane. edta had either no effect, or sometimes retarded the elevation of the fertilization membrane, or reduced the percentage of eggs with elevated membranes. theoretical considerations lead to estimates of the probable effects of egta and edta on the internally released calcium which triggers the c ...	1999	96872
antigenic variation and increase in pathogenicity in pseudomonas aeruginosa as a result of growth on glucose or n-hexadecane as sole carbon source.	when pseudomonas aeruginosa is grown on glucose as opposed to n-hexadecane as the sole carbon source, the antigenicity, virulence, and protein composition of the outer membrane are altered. the hydrocarbon-grown cells demonstrate a 3-log increase in virulence over the glucose-grown cells (in mice). there also appears to be an additional protein present in the outer membrane of the n-hexadecane-grown cells. this protein may contribute to the observed antigenic differences between the two cell typ ...	1978	96928
