The mean proportional volumes of mucous acini were more than those of serous acini except salivary glands of rodents.Conclusion: The mean proportional volume of MeCs in salivary glands associates with animal species and secretion of salivary glands.

HHF 35是近几年开始使用的识别特异性肌动蛋白（muscle-actin-specific）的单克隆抗体，作者使用它来区别肌上皮细胞和腺泡，希望通过定量测定比较肌上皮细胞的平均体积比，以了解不同动物涎腺中肌上皮细胞的发育是否存在物种间的差异及与分泌功能的关系。

Results The number of cellular apoptosis was obviously increased in multiple organs from the six patients died from SARS. The cellular apoptosis occurred predominantly in cytokeratin-positive pneumoncytes, terminal bronchiolar epithelium, CD3 + and CD8 + lymphocytes, as well as a part of CD20 + lymphocytes and CD68 + macrophages.

结果 与正常组织比较，SARS患者全身多器官组织细胞凋亡数目明显增多，尤以肺脏和免疫器官为甚，主要的凋亡细胞类型为CK阳性肺泡上皮细胞、终末支气管黏膜上皮细胞、CD3+细胞、CD8+细胞，以及少部分CD2 0 +细胞和CD6 8+巨噬细胞。

Among the 3 novel sequences, C24 sequence and C57 sequence were expressed both in cataractous group and in normal group; C24 sequence was expressed higher in cataractous group than that in the normal group, but C57 sequence had no significant difference in normal and cataractous group; C40 sequence was expressed in the cataractous lens epithelium but the expression in normal lens epithelium was not seen.

三个新序列中，C24号和C57号序列在年龄相关性白内障和正常晶状体上皮细胞中均有表达，C24号序列的表达增高；C57号序列在正常组和白内障组中的表达无差异。C40号序列在年龄相关性白内障晶状体上皮细胞中有表达，但其在正常晶状体上皮细胞中未见表达。

Results The expression of the Mahoganoid protein and its mRNA was showed by brown staining and observed in the Leydig cells, spermatogonia, primary spermatocytes, spermatids, Sertoli cells, and peritubular myoid cells of testicular tissues and principal cells, basic cells and epithelial cells of epididymal tissues.
