Urea i loko o ke koko. Hooulu ana i na ao, ua hakumakuma i ka maʻiʻo

Urea ua synthesized ma ke kaʻina hana o ka neutralization o ka ammonia ma ke akepaʻa. Ua ua hana i loko o ka reactions o'aminoʻakika deamination. Urea pili i ka hui o haʻahaʻa hakakino kaumaha. Ka mea, i ka hiki i ka 'elele i hele ma ka halepaahao membranes o erythrocytes a me parenchymal nā loko. urea mai i ke koko kānana ia lŘlŘ i loko o ka glomeruli. Akā, i ka mea ia manawa kona nui reabsorption (OE) ua lawe mai i loko o ka tubules.

Urea koko noʻonoʻo e like me ka hoʻololi kemikala o glomerular kānana ana a me kaʻaʻa puʻuwai perfusion.

Kēia hui, he haʻahaʻa kaʻawahia, akā, i ka kaʻawahia o guanidine nā mea loaʻa noho potasiuma Ion loaa me ia. Urea mea he osmoticallyʻeleu waiwai no hoi, no laila, i ka wa a ka mea, ua hoailono aku la hoʻomāhuahua o edema i loko o nā nā'aʻaʻa o parenchymatous nā loko, myocardium, Central ko mākou hopohopo nenoaiu, subcutaneous'aʻaʻa.

koko urea (kona lehulehu i ka wai koko) ua pinepine manaoia he anakahi o kaʻaʻa puʻuwai glomerular kuleana pili i noonoo. Eia naʻe, he oi pololei olelo ua hana ma luna o ka maʻiʻo o ka creatinine.

E māhuahua urea ho okumu ike ma o ka hoʻohana a excessive dala o ke kumuʻiʻo catabolic Hawaii, e like me ka pono me omo o ka kumuʻiʻo a me ka'amino nāʻakika ma hope o gastric kahe ana ke koko. Mahuahua kona lehulehu malamaia ma ka dehydration ma muli o ka nui ae OE reabsorption ma ka hakuʻala tubules.

Hoemiia ke koko urea (wai koko) ma lalo o ka kemikala hepatic papa kāna hana, e like me ka lawa kumuʻiʻoʻai ana. Ka maʻiʻo o ka hui i ka lāʻau lapaʻau e hoonui no ia i ka? Eaia o na ai 'kanaka. Mau laau lapaau nā phenylbutazone, anabolic steroid, dopegit, hao kumukanawai, aldomet, nephrotoxic ai '.

Ka ho'ēmiʻana o ka urea i loko o ke koko ke hoike ake maʻi (hepatitis, ma ka me ka mea hoʻomaʻi, cirrhosis, hikoko). O ke kumu ho i ka mea i keia kino he mea i ke kahua o ke kumu o hui. Ia lŘlŘ kue, a ake kāna hana urea? Iecaianoaaiiuo. Ma kēia hihia, na symptoms o ka maʻi hiki ole mau ke akaka hoakaka. I ka papa kuhikuhiE symptoms E e noʻonoʻo me ka nawaliwali, lilo o ka ikaika loa ka makemake, luhi, jaundice, awaawa belching, discomfort i loko o ka hypochondrium akau.

I maʻi o ka digestive'ōnaehana, pu ma malabsorption o'amino nāʻakika e i nā polokina i loko o ke au postoperative pili i uao ai 'no intestinal maʻi, maʻi pancreatitis, parasitic maʻi puʻuwai i kaulana hoemi urea i loko o ke koko. pono e kuhikuhi lapaʻau o keia ma kamaʻilio akula i ka nń ku maʻi. E like me ka rula, ma hope o Kaniak hoopakele ia o ka maʻi a me ka normalized ho'āʻo ma.

It E e hoʻomaopopo i ka maʻiʻo o ka hui i loko o ka mimi ua nānā 'ia e kona lehulehu i loko o ke koko. No hoi e lawe i ka mooolelo o ka nui o ke kānana i loko o nā puʻupaʻa.

Normal koko urea mea 2,8-8,3 mmol / ho'āo ai. Nō kāu, i ka wa a ka maʻamau kaʻina hana o ka kumuʻiʻo pūnao, kona Contents mea kākaʻikahi malama no ka oi ma mua o 6 mmol / ho'āo ai. Ina he mea heʻai haʻahaʻa ma ka kumuʻiʻo, ua hoemiia ka hui lehulehu i 2 mmol / hano.

Mahuahua urea i loko o ke koko (i hookuu i ka lehulehu i kekahi mau manawa o ka maʻamau maluna nā hoailona), IeAUPIIe, IAa IO pu ma ka loa intoxication, kapa uremia. Ua kaulana i ka like ana ma luna o ke kāʻei kua o ka kēia mau maʻi:

-ʻaʻa puʻuwai ole huʻi palapala;

- pyelonephritis, glomerulonephritis;

- anuria (wa e kaawale aku o ka mimi maʻi pale, kekahi kanaka 'aʻole i defecate);

- mimikō;

- hikoko a concrements ma ka urethra paha ureter;

- peritonitis;

- kŰia;

- phenol kaʻapu kōheoheo, o Hereme paʻakai, chloroform;
