The surfactants used in syndet are mild and high efficiency, little skin irritation. As the pH value of syndet is neutral (7) or skin neutral (5.5), they neither alter the pH of the skin nor cause puffiness skin layer. Due to the absence of lime soap formation there is no problem of skin irritation caused by lime soap residues remaining on the skin.

合成皂所采用的表面活性剂更加温和，对皮肤的刺激性非常小，而且整体呈现中性(7)或者与健康皮肤相近的 pH 值（5.5），所以对皮肤 pH 值影响很小，同时避免了长期使用碱性皂引起的皮脂流失，由于没有钙皂形成，避免了钙皂沉积造成的刺激。

Spinach, wild rice stem, leek containing oxalic acid are more advisable moment with hot water immersion to go oxalic acid dissolved in order to avoid foods with calcium into insoluble calcium oxalate.

菠菜、茭白、韭菜都含草酸较多，宜先用热水浸泡片刻以溶去草酸，以免与含钙食品结合成难溶的草酸钙。

The effects of non-metallic inclusions on the machining properties of Ca and Ca-S free machining steels,which were made in 18 t ladle by means of powder injection,were presented.

Itamin D from the skin and diet is metabolized in the lier to 25-hydroxyitamin D (Figure 1), which is used to determine a patient's itamin D status1,2,3,4; 25-hydroxyitamin D is metabolized in the kidneys by the enzyme 25-hydroxyitamin D-1-hydroxylase (CYP27B1) to its actie form, 1,25-dihydroxyitamin D.1,2,3,4 The renal production of 1,25-dihydroxyitamin D is tightly regulated by plasma parathyroid hormone leels and serum calcium and phosphorus leels.1,2,3,4 Fibroblast growth factor 23, secreted from the bone, causes the sodium–phosphate cotransporter to be internalized by the cells of the kidney and small intestine and also suppresses 1,25-dihydroxyitamin D synthesis.5 The efficiency of the absorption of renal calcium and of intestinal calcium and phosphorus is increased in the presence of 1,25-dihydroxyitamin D (Figure 1).2,3,6 It also induces the expression of the enzyme 25-hydroxyitamin D-24-hydroxylase (CYP24), which catabolizes both 25-hydroxyitamin D and 1,25-dihydroxyitamin D into biologically inactie, water-soluble calcitroic acid.2,3,4

从皮肤和食物来的维生素D在肝中代谢为25-羟基维生素D（图1），被用来决定病人体内维生素D情况的1，2，3，4；25-羟基维生素D在肾中被25-羟基维生素D1羟化酶（CYP27B1）转变为有活性的1，25-二羟基维生素D 。1，2，3，4由肾产生1，25-二羟基维生素D是被血浆甲状旁腺激素和血清钙，磷水平紧密调节。1，2，3，4由骨分泌的成纤维细胞生长因子23使钠磷协同转运蛋白被肾和小肠细胞内化及抑制1，25-二羟维生素D合成。5 在1，25-二羟基维生素D作用下肾和小肠吸收钙及磷的效率增高(图1)。2，3，6 它也包括25-羟四- 24 -羟化酶的表达(CYP24)，且将1，25二羟基维生素D和25羟基维生素D异化成无生物活性，水溶性的维生素D3-23羧酸。2，3，4
