看英國(guó)藥典,有個(gè)Raft-forming ability的檢查項(xiàng),是檢查什么的。怎么翻譯。謝謝。

要翻譯英國(guó)藥典中《Compound Alginate Antacid Oral Suspension》標(biāo)準(zhǔn)。 其中有個(gè)檢測(cè)項(xiàng)叫Raft-forming ability。查了好久都不曉得要干什么。求各位大俠給點(diǎn)提示。謝謝。 附:那檢查項(xiàng)全文。最好幫我翻譯一下。呵呵 ![]() Raft-forming ability Introduce 150 mL of 0.1M hydrochloric acid into a 250 mL beaker having an internal diameter of 60 to 70 mm. Place in a water bath such that the volume of water in the bath is level with the top of the acid in the beaker and allow to equilibrate to 36.5° to 37.5°. Using a syringe (without needle), remove a quantity of suspension, previously shaken, equivalent to one dose. Where a dosage range is specified, use the maximum dose. Wipe the outside of the syringe and add the suspension evenly into the centre of the beaker (the time taken to add the entire dose is approximately 5 seconds). After 30 minutes, remove the beaker from the water bath, dry the outside of the beaker and examine the contents. A mass is formed. |

翻譯為“成筏性”就可以了。 具體的意思,你首先要了解海藻酸的性質(zhì)和治療機(jī)理,可參考海藻酸-氫氧化鋁-三硅酸鎂 說(shuō)明書(shū)的藥理部: 本品為胃食管酸反流抑制劑。當(dāng)被咀嚼時(shí),口腔內(nèi)的唾液使海藻酸與發(fā)泡劑起反應(yīng),生成充滿氣體的海藻酸鈉凝膠,這種充滿氣體的泡沫層被稱為“筏排”,它在胃內(nèi)容物表面上浮動(dòng),由于胃內(nèi)容物為酸性,故可在界面處又沉淀出一層海藻酸,通過(guò)這種浮動(dòng)的“筏排”的物理作用阻止胃食管的酸反流,從而對(duì)下食管粘膜起保護(hù)作用。其抗酸成分(三硅酸鎂,氫氧化鋁)可通過(guò)保護(hù)胃和食管粘膜而避免胃酸的侵襲,起到輔助治療的作用。本品的作用方式與普通抗酸藥不同,因?yàn)楹T逅崮z的粘稠度可以防止本品中和大量胃酸,故不對(duì)胃內(nèi)容物的酸性有重大影響,但本品里的抗酸成分可以避免與胃酸迅速接觸,所以本品不是中和胃酸,而是以接近中性的“筏排”,形成胃內(nèi)浮游物,可提高pH值超過(guò)臨界值4,從而對(duì)下食管粘膜起保護(hù)作用。 |
