Rat brain tubulin in a proper buffered solution became insoluble in the presence of 10 mM NiCl2, and sedimented at centrifugal forces as low as 500 x g for 30 min. Both nickel-sedimented and microtubular tubulin conserved 65% of colchicine ...

The distribution of galanin (GAL)-like immunoreactivity (-LI) was studied in the CNS of the toad (Bufo arenarum Hensel). Tissue sections were incubated with antibodies directed toward rat or porcine GAL and processed either for the avidin-b...
New and peculiar cytoplasmic membranous bodies in the acinar cells of the harderian gland of the armadillo Chaetophractus villosus [0.03%]

A new and peculiar morphological feature in acinar cells of the Harderian gland of the South American armadillo Chaetophractus villosus (Mammalia, Dasipodidae) is reported. The gland of adult males and females was studied at macroscopic, mi...
Alteration of morphogenetic cell interactions by 1-beta-D-arabinofuranosylcytosine in Bufo arenarum embryo [0.03%]

Amphibian gastrulation was used as a model system to study the action of the nucleoside 1-beta-D-arabinofuranosylcytosine (Ara-C) on the early events of amphibian morphogenesis. Ara-C inhibits both glycoprotein and glycolipid synthesis and ...
Serotonin reverses the inhibitory effect of a brain soluble fraction on synaptosomal membrane Na+, K(+)-ATPase activity [0.03%]

Normal operation of the Na+ pump (Na+, K(+)-ATPase) is essential for the maintenance of neurotransmission. Filtration through Sephadex G-50 of a brain soluble fraction allowed the separation of peaks I and II fractions, respectively stimula...
Ultrastructure of Psammobatis extenta (Rajidae) electrolytes and cytochemical localization of acetylcholinesterase, acetylcholine receptor and F-actin [0.03%]
