Anal chromatin

Pinepine ma pediatric gynecology a me ka andrology he mea i pono, e hoʻomaka i ka aaiaoe ninaninau o ka hoʻomanawanui. Kēia iaoia apono 'oi ike loea e hookupaa aku i ka kumu o ka maʻi i kaua kipi, e lawe ia i ka mea e pono ai lapaau, a e hooholo i ka kēla i loko o ka ulu ana o ka maʻi.

Sex chromatin - nui i anakahi o ka maʻamau moe kūpono 'ana ma ke kelepona hele kiʻekiʻe. Konaʻike, he mea nui i loko o na ka wā e hele mai ai i na anomalies i loko o ka 'ole o ka mea mawaho genitalia. Ua like me ka mākaʻi like me ka ka loaʻaʻana o ka mai, kena ae la ia e chromosomal abnormalities ma ke alo o ka hoʻopōʻino moe? Acaeoey. Ke kumu no keia e malama i ka wa e kaawale aku o ka menstruation i kaikamahine, a hypoplasia o na ovaries a ho'ēmi i kā lākou mau hana i loko o nā keikikāne.

Sex chromatin i mua loaa e nä känaka 'epekema John. Bar i ka 1949. E mālama nei noiʻi o nā aʻalolo keena nā pōpoki, oia ka olelo ma ka periphery o ka nucleus chromatin ho okumu. A laila, i 'akomi i keia pono o ka wahine somatic keena ma ka hapanui o na elele o ka mea o mammals. Ke kane aeee na corpuscles iʻaʻole i loaʻa. Barr kino o ka ke keʻena o nā mea a pau kino keena o na wahine. A i loko o kekahi manawa ia i keʻano o nā appendages ( "drumsticks"). Somatic aeea - integral māhele o ke kanaka kino. O nā mea a pau kino keena koe na gametes. Kēia loaʻa 'ae' e hoʻonui i ka manaʻo o nā kiʻina hana o ke keka hoʻoholo i loko o kānaka a me nā mammals.

Ke alo aku o ka wahine kino Barr kino aie i ke alo o somatic aeee i loko o ka mau X chromosomes. ¶ ha awina i wale kekahi o ia mau mea. I mea no ke aha la i loko o ka wahine o ka keena, he mea mau he Barr kino. Kēia kumumanaʻo ua hou ia huai ae anomalies i loko o ka ulu ana o ka meaola. No ka laʻana, he aeea me ekolu chromosomes, e i mau bipi kāne, a me eha - ekolu, etc. ʻike, o'āno'ē aeea? Acaeoey hiki ke hoʻohana 'ia no nā kānaka a me nā wāhine. Mai 1953, ua loaʻa i ua hoʻohana nui e hooholo i ka kiko'ī helu o X chromosomes i loko o kanaka me developmental ke kino kīnā.

Moe chromatin a Barr kino, me ka pouli nui kohu ka ua hoʻokōʻia, triangular paha kookoo-hoʻokino, i kahi kokoke i ka pahale ili o ka nukeleaʻili lahilahi. Kēia AEeOEXAaI X-chromosome, a ma kona anawaena mea emi o 1 micron. Ka loaʻaʻana o Barr kino i loko o keena o 10-12% o ke ao Hōʻike he maikaʻi moe chromatin. Research mea ana lawelawe 'ana i ka epithelium o ka buccal mucosa (ka pahale ili), vagina, lauoho follicles a me amniotic loli. Inā ka huahelu, aole ia i oi aku mamua o 5%, e hōʻike i ka io moe chromatin.

Sex chromatin ke kumu oko ao ma interphase nuclei i loko o nā kānaka a me nā wāhine. Ua Ua pili i nā hiʻona functioning wahine nenoai a me kā lākou 'ole. Barr kino mea a mau ano: Y a me X. keʻano mua o he mall ke keʻena o ka Y-chromosome, a ua 'akomi i ka hapanui i loko o nā kānaka. No kēia mau hana fluorochrome hoʻohana 'ultraviolet malamalama. X-chromatin (Barr kino) - ua inactivated X chromosome. Kona deactivation ia lŘlŘ i loko o ke kakahiaka pule o fetal? Acaeoey, a ua hūnāʻia ma ka mitosis no ka lōʻihi manawa.

It E e hoʻomaopopo i ka ke keka chromatin - mea he hōʻeuʻeu 'ole. Ua hiki oko ma luna o ka nohona ma ke ano o ke kino, a me ka pūnao o aeee. Ia mea no keia kumu, e alakai i ka anamanaʻo ua ole e waiho ma ka hoʻohana 'ana o hormonal hoomakaukau, i ka lā mua ma hope o ka hānau, ma hope o ka lawe antibiotics a me' ē aʻe ai '.

I keia la, i ke alo o ke keka chromatin kauka ho oholo i ka aaiaoe ke keka o ke keiki, diagnosed me nā lapaʻau ano o gonadal dysgenesis a me ka hermaphroditism. Assays no ka 'ike o ka ke keʻena hoʻomano hoʻohana ma forensic hana.
