The results of the ultrastructares of the glandular hairs show that there are a number of the plastids in which there are a big of osmiophilic substances in the secretory cells of the peltate hairs and then that there are much endoplasmic reticulum in the secretory cells of head hairs. The difference between them are with relation to the function.

腺毛超微结构观察的结果表明，盾状腺毛类分泌细胞的优势细胞器是质体，其中具大量的嗜锇物质；而头状腺毛类分泌细胞的优势细胞器是内质网，这种细胞器上的差异与头状腺毛和盾状腺毛的分泌功能是相适应的。

At early stage of cancer cell formation, provoked autophagy help to eliminate damaged cell organelle、and degrade the noxious substance in endochylema(eg: peroxidate)as well, pretect normal cells from cancerization.Autophagy level modulation might be cooperation or rivalry with chemotherapy to cancer cells compares to single use of chemotherapy drugs, apoptosis rate of cancer cells fluctuates with autophagy level.
