致密斑

结果表明，泰和鸡的肾小球旁器由球旁细胞、过渡型致密斑、球外间膜细胞和极周细胞所组成。

The results show : The JGA of Taihe fowl consisted of juxtaglomerular cells , transitional macula densa , extraglomerular mesangial cells and peripolar cells .

肾素合成的调节可独立于致密斑，但后者对肾素分泌起重要调节作用。

The mechanism in control of renin synthesis is independent of the macula densa , but the latter is critical in the control of renin secretion .

结论：雄激素可通过参与调节肾脏致密斑NOS活性的变化影响肾脏功能。

Conclusion Androgen can adjust the blood flux of glomerular by regulating the NOS activity of macula densa , and affect the kidney function .

低盐通过激活ERK和AP-1通路诱导小鼠致密斑细胞系COX-2的表达

Low salt induces the expression of cyclooxygenase-2 in a mouse macula densa cells through the activation of ERK 、 AP-1 pathways

低盐诱导的致密斑细胞环氧化酶2表达与p38丝裂素激活蛋白激酶信号通路

Low salt stimulates the expression of cyclooxygenase-2 and its relationship to p38 MAPK signal transduction in a mouse macula densa cell line

致密斑在管球反馈和肾素分泌中的作用

Effect of macula densa on tubuloglomerular feedback and renin secretion

肺实质呈致密斑点状强回声。

The lung parenchyma appeared echo rich and patchy .

而患者组血小板形态、线粒体、致密斑颗粒、糖元颗粒与对照组比较均有显著变化或减少（P<0.001）。

Microcirculation changed significantly in patients compared with control ( P < 0 . 001 ) .

10周可分近曲和远曲小管，致密斑可见。12～13周出髓袢。

The proximal convoluted and the distal convoluted tubules may be distinguished and the macula dense may be discovered at week 10.During the 12th-13th weeks , the medulary loops are found .
