查询词典 urea-formaldehyde

Twenty-four hours after the last oral administration, the blood were obtained and used for testing adrenocorticotrophic hormone, cyclic adenosine monophosphate, cyclic guanosine monophosphate, glucose, cholesterol, alanine aminotransferase, urea nitrogen. Results Before taking medicine, model rats' cAMP/cGMP and ACTH were lower than normal rats', and they showed a trend of rise with adding dose. Before taking medicine, model rats' GLU was lower than normal rats'. With adding dose, model rats' GLU increased, however, normal rats' GLU reduced. When taken medium dose white prepared lateral root of aconite, model rats' CHO was higher than normal rats'. Taking medicine made both groups ALT rise, but normal rats' went up more quickly than model rats'. Model rats' BUN was higher than normal rats', and taking low dose or little dose medicine could lead to incline of reduction.

结果 给药前模型组环磷酸腺苷/环磷酸鸟苷和促肾上腺皮质激素低于正常组，随着给药剂量的增加，两者有升高的趋势；给药前模型组血糖低于正常组，随着给药剂量的增加，模型组GLU有升高的趋势，而正常组有下降的趋势；中剂量给药时模型组总胆固醇显著高于正常组；随着给药剂量的增加，2组丙氨酸氨基转移酶均有升高的趋势，且正常组ALT升高的幅度更大；给药前模型组尿素氮高于正常组，低、小剂量给药有降低模型组BUN的趋势。

The mutants were further screened through repeated fermentations as well as the measurement of their physical properties. The results showed that some major fermentation indexes of strain HJ1615-d4 such as alcoholicity, fermenting power,total acids and flavoring components etc. were almost the same as those of the original strain. However, its urea yield was only 15.41 mg/L, louer 50 % than that of the original strain.
