A general Sierpinski block generated by normal tetrahedron is constructed by making use of the contraction of identical mapping which meets the open set conditions,and finds out its Hausdorff dimension s=ln[4+6(n-1)]/ln(1/ε).
Results After incubation with E2(10-5,10-4.2 mol/L),the phasic contraction induced by KCl was inhibited in a concentration_dependent manner in artery rings (IC50 was 10-4.8 mol/L), and the concentration effect curve generated by 5_HT was also inhibited (pD2' was 4.57).
The phosphorylation and dephosphorylation of 20KD myosin light chains(MLC20) by Ca2±/ Calmodulin(CaM) dependent myosin light chain kinase (MLCK) and myosin light chain phosphatase (MLCP) play the key role for the regulation in smooth muscle contraction.
Using the bioassay of porcine coronary artery strips, F 3(10 -6 , 10 -5 and 10 -4 moL/L)were added into the bath medium prior to KCl(10～40mmoL/L)administration to observe the effect of F 3 on dose-response curve of contraction induced by KCl, and the block action of F 3(10 -4 moL/L)on the contraction induced by KCl respectively;
By this theorem we can improve a fixed point theorem for weakly inward contraction set-valued mapping of D.
For the vector problem with subtests of the form MINMAX MODUL, the necessary and sufficient stability conditions were established (retention or contraction of the Pareto set for "small" variations in the source data).
The stability of soil conditions allows considerable contraction of the realized niche volume, which increases species richness in soil.
CB receptor activation by HU-210 (0.1 and 1 μM) in vitro decreased the rate and force of isolated heart contractions, the rates of contraction and relaxation, and end diastolic pressure.
