    Notes: Abstract The effects of dexamethasone (DEX) and ϖ methyl ester (l-NAME) on the tumour necrosis factor-α (TNF-α)-induced increase in permeability of human umbilical vein endothelial cell (HUVEC) monolayer to [125I] labelled bovine serum albumin (BSA) were examined. Preincubation of HUVEC monolayers with DEX (1μM, 2 h) completely abolished the effect of TNF-α (5 ng/ml, 18 h). Administration of DEX 2 h after TNF-α also reduced the effect of TNF-α, whilel-NAME (5 ng/ml, 1 mM, 18 h) had no significant effect. The observed inhibition of the TNF-α-induced permeability increase on preincubation with DEX would suggest a role for nitric oxide (NO) in mediating the permeability response. However, this is not confirmed by the experiments withl-NAME. The inhibition caused by DEX administered after TNF-α would suggest alternative mechanisms by which DEX may be acting in addition to inhibition of NO synthase induction.

    Notes: Abstract. New neutron-deficient isotopes 188,189Po have been produced in the complete fusion reaction of 52Cr ions with a 142Nd target at the velocity filter SHIP. The evaporation residues were separated in-flight and subsequently identified on the basis of α-γ and α-conversion electron coincidence measurements and of α-α position and time correlations. In 189Po a ground state to ground state α decay with Eα1= 7540(20) keV, T1/2= 5(1) ms and two fine structure α-decays at Eα2= 7264(15) keV and Eα3= 7316(15) keV have been observed. In 188Po (T1/2= 400+200 −150μs) a ground state to ground state α decay at Eα= 7915(25) keV and a fine structure α decay at Eα= 7350(40) keV have been found. Improved data on the α-decay of 189Bi were obtained.
