METHODS: Rat bilateral olfactory bulbs and olfactory mucosa at 1/3 nasal septum were obtained, sliced, digested in trypsin, and made into monoplast suspension. At 1×109/L, cells were incubated in uncoated 25 cm2 culture flask. At 18-20 hours, cell suspension was moved into another uncoated 25 cm2 culture flask (the first differential adhesion). At 24 hours, cell suspension was moved into a poly-D-lysine-coated 25 cm2 culture flask or poly-D-lysine-coated 6-well culture plate (the second differential adhesion). At 48 hours, parenchyma cells were removed after a half of medium was changed.

In present study, the model of the low shear stress in carotid or hypertension was established by the ligation of partial distal branches of the left common carotid or the coarctation of aorta in SD rats respectively. In some rats the low shear stress in carotid was accompanied by the hypertension. The media and intimal thickness, as well as the ratio of vessel thickness to inner diameter were determined by morphometrical approach.

The fiber length has only little influence on the basic density within the growth rings, and significant correlation at 0.01 levels was found between the basic density and the fiber length among the different rings. Only slight negative correlation was found between the basic density and the fiber width within the growth rings, but significant positive correlation at 0.01 levels was indicated between the basic density and the fiber width among the growth rings, contrary to that of fiber length. It was demonstrated that significant positive correlations at 0.01 levels between the basic density and fiber double wall thickness, fiber length to width ratio and double wall thickness to diameter ratio, significant negative correlations at 0.01 levels between the basic density and fiber diameter and diameter to width ratio, only slight negative correlation between the basic density and fiber width both in the same growth rings and among the different growth rings. No significant correlation was found between the basic density and the vessel morphological features, nor was the tissue proportion in the same growth rings. But among the different rings, it was found there was significant positive correlation at 0.01 levels between the basic density and the fiber proportion among the different rings, and significant negative correlation at 0.01 levels between the basic density and vessel-elements proportion and ray proportion, only slight negative correlation between the basic density and the parenchym proportion. Significant or no significant negative correlation was found between the basic density and the microfibril angle in the same growth rings, but significant negative correlation was found between the basic density and the microfibril angle among the different growth rings.

生长轮内纤维长度对基本密度的影响不大，而在不同生长轮间纤维长度与基本密度达极显著正相关，纤维宽度与此相反，同一生长轮内纤维宽度与基本密度极显著负相关，不同生长轮间只有微弱负相关；基本密度与纤维双壁厚、长宽比、壁腔比在生长轮内和生长轮间均呈极显著正相关，而与胞腔直径、腔径比均呈极显著负相关，仅与纤维宽度呈微弱的负相关；导管形态对基本密度的影响不显著；同一生长轮内组织比量对基本密度的影响也不显著，但不同生长轮间基本密度与纤维比量呈极显著正相关，与导管比量和木射线比量呈极显著负相关，与轴向薄壁细胞比量仅呈不显著负相关；生长轮内基本密度与微纤丝角呈显著或不显著负相关，但在生长轮间这种负相关达到极显著水平。
