Oncotic puʻe

Inherently oncotic puʻe (ka mea, i ka ia osmotic) - i huiʻia e hoike mai i ka hanaʻia, ke kumu o ke koko, a me ke koko wai koko. Me ka shortage o nā polokina i loko o ke kino ua ua hoʻemi, a e alakai ai i ka mea i pono, e hoʻomāhuahua ana o edema loli, e hoʻomaka i ka hōʻike. O ke kumu ho i ka mea e, ua translucent a semipermeable kaʻili lahilahi moku pa. Ka mea, ua pono a me ka uku ole ia mai kekahi, ka wai, oiai na Ion, a na nā lātoma o kekahi mau waiwai - nahae.

Normal oncotic puʻe mea e pili ana i 7,5 atm. (5700 mm o Hg ole 762 kPa). I ka ha awina loli aʻe i loko o ka wai koko māhele 290 mOsm / ho'āo ai.

Naʻe, ka mea osmotic puʻe ua anaia mai ka manawa i ma ka nui o ka mea hoʻoheheʻe nā lātoma, e like me kā lākou lehulehu. Ka hapa nui o ka wai koko Ion (ma kahi o 99,5%) i ka'okanikaʻole Ion, i ka lehulehu o ka i hilinaʻi nui oncotic puʻe. Ka puʻe o ka wai koko nā polokina mea wale nō i ka hapaʻuʻuku o nā mea a pau 0.03-0.04 atm. (25-30 mm o Hg). Akā, e pono ke kuai e hoomanao ana i ka manaʻo koikoi ka lawe 'ana ma nā polokina kekahi pilikia kūlana ma ka puunaue ana o ka wai ma waena o ka wai koko, a me ka papa kuhikuhiE nā'aʻaʻa Radio.

Kēia hapa o ka kaʻina hana a me ka noonoo i ka 'ike o oncotic puʻe. Kona komo i loko o ka puunaue ana o ka wai ua hōʻikeʻia e ka mea i ka paia o ka capillariesʻano nui impassable no nā polokina. Ke interstitial loli nā polokina nui uuku, no laila, i ko lakou lehulehuʻano piʻina ua loaa ma na aoao a elua o ka capillary.

Aie i ka mea kiʻekiʻe oncotic puʻe o ka loli ma ka intercellular makahiki, aole i loaa, a me circulates.

No ka mea Kāohiʻana o oncotic puʻe paipai lapaʻau o preeclampsia, i mea he nui-no laila, i ka hopena e ole lawe lōʻihi. Me ka maʻamau koko clotting nā polokina normalize ia, hiki e emi i ka pilikia o ka naau maʻi.

Oncotic ke koko, ua ana mālama i ka ikaika kiʻekiʻe. Ma kona neurohumoral hooponopono komo excretory nā loko e like me ka hou glands , a me nā puʻupaʻa. Emi paha mahuahua ae oncotic puʻe ike ma ka periphery o ka moku paia, a me nā kikowaena hapa (ka hypothalamus) kahi antidiuretic hōmona ua hookuu ia mea e loli ai ka omo kaʻina hana i loko o ka hakuʻala kaha. Kona kuleana pili i ka mea e hooponopono i mimi ho okumu kaʻina. Ke kumupaʻa o ka osmotic puʻe i ADN, aldosterone, parathormone, urenichesky cardiac hōmona.

By reflex ia lŘlŘ i loko o ka hoʻokaʻawale 'nā loko hoʻololi i nā hana a kūpono ma excessive' ole, a me ka ulia poino o ka loli a me ka paʻakai i loko o ke kino. Ma kēia mau keʻano o ka hanaʻana, ka mua a me ka kūlana Hoʻohaku hele nā polokina (oncotic puʻe) a e hiki ke hoopaa a me ka hoʻokuʻu Ion. Ma na hana o excreting nā loko (konāhuaʻelua a me ka hou glands), metabolic huahana, a e noke i hanaʻia i loko o ke kino, ka hapanui o ia mai i ka hopena maikaʻi 'ole ma o ka osmotic puʻe.

Kāna hana oncotic puʻe pae i pili me ka imbalance o ka huina kumuʻiʻo wai koko albumins a me globulins, anions, cations, paʻakai, potasiuma, kalipuna a me nā eiiiiiaiou. Ua hiki e kena ae la ia e likeʻole pathological kūpono a me nā maʻi (intoxication,'ā, lāʻau kū-operative manawa, kŰia, hemorrhage, maʻi likeʻole, a me ka mea e like). Ma na hihia a pau, e kaha i ka oncotic puʻe mea loa nui e mau. Lapaʻau ua kuhikuhi kuhikuhi i wehe i ka nń ku mai a me ka hoihoi hou ia ana o ke koena o ka paʻakai i loko o ke koko wai koko. Naʻe, ma mua oe i hana i ka manaʻo koikoi, o ka oi aku oncotic, eʻoiaʻiʻo, e kukakuka pu me kou kauka. Mai Mai pakiko-lapaʻau!
