Tumor blood flow is an important determinant of the efficacy of presently available antineoplastic treatment modalities. Using l13Sn-labeled microspheres, 25 u.m in diameter, we measured blood flow to primary tumors and regional lymph node métas tases in conscious SMT-2A mammary adenocarcinoma-bearing syngeneic rats following a single i.v. bolus injection of the calcium entry blocker, flunariz...

1. The capacity of low-density lipoprotein-cholesterol (40 micrograms/ml) to stimulate both the phosphoinositide cycle and the dislocation of the phospholipid- and calcium-dependent protein kinase C activity from the cytosolic to the membranous compartment in human circulating lymphocytes has been studied. 2. Pretreatment of lymphocytes with pertussis toxin inhibited significantly the low-densi...

The efficacy of Flunarizine (FLU), a calcium channel blocker, in combination with conventional antiepileptic drugs, phenytoin (PHT), carbamazepine (CBZ), sodium valproate (VPA), and ethosuximide (ESM), at ED50 doses, were examined for protective effects against maximal electroshock seizures (MES) and pentylenetetrazol (PTZ) induced seizures in mice. In both models, only VPA and FLU showed signi...

In the present work, Flunarizine hydrochloride, an anti-migraine drug has been formulated into fast dissolving tablets by sublimation method using camphor and menthol as sublimating agents and treated agar as superdisintegrant. Concentrations of the sublimating agents were varied keeping the concentration of superdisintegrant fixed. The aim of the study was to prepare fast dissolving tablets wi...
