Gscoh gs fsR, gscoh as the solid fraction when the formation of the continuous dendrite framework, fsR as the maximum solid fraction after recalescence,βs as the solidification shrinkage of the primary phase,μas the dynamic viscosity of the liquid, a as the length of L/S coexistence zone,λ2 as the secondary dendrite arm spacing, and tf as the total solidification time. High temperature recovery and recrystallization taking place in these fragments during further cooling results in the further grain size decrease.

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P<0.01~0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P<0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.
静息状态下收缩时间间期与年龄无相关性,负荷后即刻,老年组射血前期延长(P<0.05),射血前期与射血期比值加大(P<0.05),青年组无变化,提示年龄因素亦影响STI,但由于静息状态下得到代偿,STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化,而负荷后即刻老年组PEF延长,PEP/LVET加大,提示STI是检测左室收缩功能的敏感指标。4、随年龄增长,心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r=0.958、0.956、0.986及0.966,P均<0.001),舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r=-0.958、-0.875及-0.937,P<0.01~0.001)。

Methods; Rat HSCs were treated with 0.4% fetal calf serum/DMEM for 48 hours and divided into the control group and experiment groups. HSCs in the control group were treated with 10% FCS, and HSCs in the experiment groups were treated with 10% FCS and low anticoagulative activity heparin with different concentrations (8 g/L, 40 g/L, 200 g/L, 1000 g/L, 5000 g/L). MTT reduction assay was used to evaluate the effect of low anticoagulative activity heparin on the growth of rat HSCs.
