解析 当血清钾浓度降低时,肾小管上皮细胞内钾移到细胞外,细胞外液的H+移到细胞内,以致肾小管上皮细胞内钾浓度降低、H+浓度升高,故向管腔中排钾减少而排H+增多,HCO-3回收增多,此时,尿液呈酸性,出现酸性尿。由于低钾血症可产生碱中毒,碱中毒时一般应出现碱性尿,而此时出现的为酸性尿,故称为反常性酸性尿。

We previously found that RP3V kisspeptin neurons are specifically activated by male odors derived from either urine19or soiled bedding in female mice. To determine the olfactory input pathway impinging onto these cells, we selectively ablated the vomeronasal organ (VNO) by surgical removal and/or t...

Whether hyperuricemia is a true risk factor for elevated blood pressure (BP) is controversial, and the sex-specific effects of serum uric acid (SUA) on BP during a follow-up period remain unclear. We investigated whether the association of SUA level with systolic or diastolic BP during a 10...
Although recommended (e.g. by the German STD society), screening for asymptomatic bacterial STIs, including pharyngeal and rectal swabs for Gonococci, or nucleic acid testing of urine or rectal swabs for Chlamydia, is thus rarely offered. It has been described repeatedly that GPs or infectious...
