Pineoblastomas arise from pineal parenchymal cells and are less common in children than other pineal germ cell tumors. 松果体母细胞瘤源自松果体实质细胞,在儿童中,发病率低于其它松果体生殖细胞肿瘤。
Melatonin ( Mel) is a kind of nerve incretion secreted by pineal gland cells. Its becoming one of the research hotspots owning to the complex physiological and pharmacological effects on multiple systems and organs. 褪黑素(Melatonin,Mel)是松果体腺细胞分泌的神经内分泌激素,由于其在多系统、多脏器发挥着复杂的生理、药理作用,因此日益受到人们的重视而成为研究的热点。
Effects of pineal gland on immune cells in normal and adjuvant arthritis rats 松果体对正常及佐剂性关节炎大鼠免疫细胞的影响
In order to study the circadian changes of activity of the pineal organ, long-term recording was performed from light-sensitive ganglion cells of the frog's epiphysis cerebri responding inhibitory to light. 为了研究青蛙松果体的昼夜节律,本实验采用细胞外连续记录,研究了松果体内对光产生抑制反应的光敏神经节细胞放电的昼夜节律变化。
Conclusion: These results indicated that WBI with LDR could promote DNA synthesis of pineal gland cells in mice. 结论:低剂量电离辐射可促进小鼠松果腺细胞的DNA合成及增殖。
Role of Pineal Gland and Melatonin in the Differentiation and Development of T Cells in Rat Thymus 松果体及褪黑素在大鼠胸腺T细胞分化发育中的作用
Conclusion: Low dose radiation can inhibit the apoptosis of pineal gland cells. 结论:低剂量辐射可抑制松果腺细胞的凋亡。
Results The pineal capsule was composed of a layer flattened epithelial cells and a subepithelial connective tissue. 结果松果体囊由一层扁平上皮细胞和上皮下结缔组织构成。
In the cytoplasm of a small number of pinealocytes exist somatostatin-immunoreactive positive substance. Some primary cultured pineal cells could synthesize and secrete somatostatin. 少量松果体细胞的胞质内,含有生长抑素免疫反应阳性物质。有些体外培养的松果体细胞,可以合成和分泌生长抑素。
