The reactivity of the various components of the Golgi apparatus of rat spermatids for three phosphatase activities (nicotinamide adenine dinucleotide phosphatase, NADPase; thiamine pyrophosphatase, TPPase; cytidine monophosphatase, CMPase) and the incorporation of 3~H-fucose by the spermatids were analysed at the four phases of spermiogenesis. The results indicate (1) that the Golgi apparatus of spermatids undergoes a series of morphological and cytochemical changes during spermiogenesis; (2) that the Golgi...

The reactivity of the various components of the Golgi apparatus of rat spermatids for three phosphatase activities (nicotinamide adenine dinucleotide phosphatase, NADPase; thiamine pyrophosphatase, TPPase; cytidine monophosphatase, CMPase) and the incorporation of 3~H-fucose by the spermatids were analysed at the four phases of spermiogenesis. The results indicate (1) that the Golgi apparatus of spermatids undergoes a series of morphological and cytochemical changes during spermiogenesis; (2) that the Golgi apparatus of spermatids, although it loses its CMPase positive GERL element in acrosome phase, retains evidence of functional capacity until it degenerates in maturation phase; (3) that in early spermatids the various saccular components of the Golgi are specialized with respect to enzymatic activities; and (4) that each Golgi region may contribute in a coordinated fashion to the formation of the acrosome system and multivesicular bodies.

Changes in the morphology of cultured cancer cells during the cell cycle were studied by using several techniques. Cells of stage Gl were obtained from two kinds of cancer cells synchronized with an excess of double-thymi-dine, cells of stage S were determined by pulse labelling with 3H-TdR auto-radiography and liquid scintillation counter. Under the scanning electronic microscope, changes in the surface structure of the cancer cells were observed. The changes in DNA and RNA in cultured cancer cells in the cell cycle were studied with fluorescent microscopy. The functional significance of regular dynamic changes is discussed.

Male Wistar rats were performed 70% partial hepatectomy (PH) or 1.5mg/g body weight D-galactosamine injection (Gal) intraperitoneally. From the 1st to the 7th day after treatment, the serum concentration of alpha-fetoprotein (AFP) and albumin (ALB) was measured and the liver sections were stained with routine and immunohistochemical methods and observed with light and electron microscopy.

大鼠肝大部切除后和D-氨基半乳糖肝中毒后第1~7天,逐日取肝组织及血液样本,观察两种类型损伤后肝再生中肝细胞的增殖分化,以及血清甲胎蛋白(AFP)与白蛋白(ALB)浓度变化及其免疫细胞化学变化。结果表明:1.肝大部切除后肝细胞分裂高峰(1.5%)出现于术后第2天,半乳糖肝中毒组的高峰在第3天,且峰值仅为前者的一半(0.8%)。2.半乳糖肝中毒后,门管区和小叶周边带出现许多小型细胞,而大部切除后的肝内无此种小型细胞。3.AFP与ALB免疫细胞化学观察表明,两种损伤后肝再生中均有AFP阳性肝细胞,于第2~3天增多,第4天后渐少。部分小型细胞呈AFP阳性。电镜下见粗面内质网、滑面内质网、高尔基复合体及核周隙等处显示AFP阳性。ALB阳性细胞第1~3天较少,于第4天起渐增多。4.血清AFP含量于第1天开始升高,第4天达高峰,此后下降,ALB含量变化恰与AFP相反,第3天下降至最低点,此后回升。
