尿素酶

Arginase, which converts arginine to ornithine and urea, is a kind of enzyme in urea cycle. It plays a significant role in N mechabolism.

精氨酸酶是尿素循环中的一种酶，催化精氨酸水解产生鸟氨酸和尿素，在机体氮代谢方面起了重要作用。

The results showed that there was a distinctly different effect on urease activity by the three different herbicides.

脲酶在尿素转化过程中起关键作用，当尿素施人土壤后，在脲酶的催化作用下，迅速分解成COz和NH。。

The results showed that granular urea amended with dicyandiamide and N- thiophosphoric triamide induced the highest soil nitrate-reductase activity, granular urea brought about the highest soil urease activity and microbial biomass C a...

Methods:After diagnosis of varioliform gastritis was made by gastroscopy,biopsy was taken,regular pathological examination was made.

对胃镜诊断的痘疹性胃炎，取活检，常规病理检查，用快速尿素酶法及GIEMSA染色检测幽门螺旋杆菌。

It is important to keep in mind that the urine can be alkalinized by the presence of ureasplitting organisms in the urinary tract.

我们必须记住，如果尿路中存在能产生尿素酶的微生物，尿液可以被碱化。

As hollow fiber membranes thickness are different, yet urea clearance rate in simulation solution is relatively high, which can reach more than 64% and little difference among them; the BSA have a relatively high rejection, which can be achieved over 98%. There is a certain difference in the Lysozyme clearance rate, the smaller thickness, the higher the rate of removal, and the removal rate of 10μm thickness of the membrane is 29%. The clearance rates of urea were very high using different fiber diameter dialyzers, at around 80%. Urea clearance ratecan reach to the highest 88.6% using 0.26mm fiber diameter dialyzer. The clearance rates of Lysozyme vary greatly, the smaller the diameter, the higher clearance rate, and the highest removal rate of lysozyme is 62.79% using 0.26mm fiber diameter dialyzer. However, there is little impact on the rejection of BSA, which can reach 98%.

不同壁厚中空纤维膜透析器对模拟液中尿素的清除率均可达到64％以上，且差异不大，对牛血清白蛋白的截留率均可达到98％以上，对溶菌酶的清除率有一定的差异，壁厚越小清除率越高，壁厚为10μm的膜对溶菌酶的清除率为29％；不同纤维内径透析器对尿素的清除率均在80％左右，纤维内径为0.26mm的透析器对尿素的清除率最高，达到88.6％，对溶菌酶的清除率差别很大，内径越小，清除率越高，内径为0.26mm的透析器对溶菌酶的清除率达到62.8％，对牛血清白蛋白的截留影响很小，截留率都能达到98％以上。

HP status was determined by rapid urease test and methyl blue stain.

Methods there 2 395 patients from ten counties or cities in han group in hainan at gastrointestinal out-patient department of the hospital were detected by rapid urease test of h.pylori and gastroscope. the posititives of rapid urease test of h.pylori were determined with 14c-urea breath test (14c-ubt).two positive tests were confirmed to be infected with h.pylori.

选择海南汉区10个县市2 395例具有上消化道症状就诊患者，经胃镜检查并取胃窦黏膜做h.pylori快速尿素酶试验，阳性患者做14c呼气试验，两者阳性确定为幽门螺杆菌感染。1 004例幽门螺杆菌阳性患者取胃窦及病变部位胃黏膜做病理组织检查。

Objective To survey the prevalence of Helicobacter pylori in gastrointestinal out-patient department in Han group in Hainan. Methods There 2 395 patients from ten counties or cities in Han group in Hainan at gastrointestinal out-patient department of the hospital were detected by rapid urease test of H.pylori and gastroscope. The posititives of rapid urease test of H.pylori were determined with 14C-urea breath test (14C-UBT).Two positive tests were confirmed to be infected with H.pylori. Biopsy was performed on 1 004 patients positive for H.pylori. 113 healthy people were enrolled in control group.

目的 调查海南汉区在消化内科就诊患者中幽门螺杆菌（Helicobacter pylori，H.pylori）感染患病情况，以及幽门螺杆菌感染与胃黏膜病理的关系方法选择海南汉区10 县市2 395例具有上消化道症状就诊患者，经胃镜检查并取胃窦黏膜做H.pylori快速尿素酶试验，阳性患者做14C呼气试验，两者阳性确定幽门螺杆菌感染。1 004例幽门螺杆菌阳性患者取胃窦及病变部位胃黏膜做病理组织检查。
