The main results were as follows:There was significant correlation between the soil urease and phosphatase activities, which showed no significant difference upon different plots. The urease and phosphatase activities in the soil were higher in spring than autumn, which under mangrove plants were all higher than those in the New alluvial soil without plants and Bared land. Soil urease activity exhibited no significant difference under different mangrove species. The phosphatase activity in the soil of Centenary Aegiceras corniculatum and Spartina alterniflor was the highest, which was the higher in the soil of Kandelia candel and Avicennia marine.

Methods Marrow cells from NH mouse were harvested and cultured in α-MEM with 10% fetal bovine serum.The appearance of tartrate-resistant acid phosphatase-staining multinuclear cells and formation of bone resorption pits were measured after 3,6,9 and 12 day exposure to various concentrations of 1,25-2D3 in culture. Results 1,25-2D3 (concentration higher than 10-9mol/L) could induce recruitment of OLCs and their bone resorption activity in a dose-dependent manner.

收集NH小鼠骨髓细胞于含10%胎牛血清的α-MEM培养基中行体外培养，设置不同的1，25-2D3浓度组和给药时间组，并于培养第3、6、9、12天观察记录抗酒石酸酸性磷酸酶(tartrate-resistant acid phosphatase，TRAP)阳性多核巨细胞［或破骨细胞样细胞(osteroblast-like cell，OLC)］以及骨磨片上骨吸收陷窝的数目。

Elevated levels of phosphatase and tensin homolog deleted on chromosometen have been reported in mammary gland tumors in humans.

有关酪氨酸磷酸酶基因(Phosphatase and tensin homolog deleted on chromosometen，PTEN)在乳腺肿瘤中的检测在人医早有报道。

For long-term treatments, the rat administered daily by gavages for six weeks, the results of OGTT showed that guava fruit water or alcohol extracts could reduce the plasma glucose level in the diabetic Wistar rats, however there was on significant difference in insulin level among all tested groups. The results of carbohydrate metabolism showed diabetic Wistar rats administered with 200 or 400 mg/kg BW of guava fruit water or alcohol extracts could decrease more than 15% glucose-6-phosphatase and fructose-1,6-bisphosphatase activities, and it also increase more than 12% glucose-6-phosphate dehydrogenase activities to reduce inhibitory hexokinase from reducing glucose-6-phosphate level.

在醣类代谢方面，实验结果发现糖尿病鼠灌食番石榴果实水及乙醇萃取物六周后，肝脏醣质新生作用中丙酮酸合成肝醣之关键酵素glucose-6-phosphatase及fructose-1，6-bisphosphatase的酵素活性会降低15%以上；另一方面肝脏glucose-6-phosphate dehydrogenase酵素活性则明显增加12%以上，并造成glucose-6-phosphate浓度减少，进而降低其对hexokinase的抑制(因为hexokinase受其代谢产物G-6-P的浓抑制)，因此加速肝脏葡萄糖的糖解作用。

RESULTS: Alkaline phosphatase activity: Alkaline phosphatase staining of cells was apparent; gray-black particles or massive precipitations were observed in cytoplasm after positive reaction; regions expressing alkaline phosphatase activity were brown-black.

结果：①碱性磷酸酶活性：经诱导后细胞碱性磷酸酶染色明显，胞质中刚性反应呈现灰黑色颗粒或块状沉淀，碱性磷酸酶活性部位呈棕黑色。

Protein phosphatases are crucial for cell living. Protein phosphatase 2A (PP2A) is an important member of serine/theronine protein phosphatase family, which is involved in almost all biological processes in eukaryotic cell. The 3D structure of PP2A core enzyme and holoenzyme was solved in 2006. These results are significant instructions for us to further understand PP2A structure, interactions between PP2A subunits, and also interactions between PP2A and its binding proteins.

蛋白磷酸酶在细胞的生命活动中起着十分重要的作用，蛋白磷酸酶2A(protein phosphatase 2A， PP2A)作为蛋白磷酸酶家族中十分重要的一员，它几乎与所有真核细胞的生命活动都有密不可分的关系。2006年，PP2A核心酶和全酶晶体结构的陆续破解对于深入了解PP2A自身的结构和亚基之间的相互作用，以及其与结合蛋白作用的机制都有重大的影响。
