Hujayra fabrikalarifarmatsevtika ishi, vaktsinani ishlab chiqish va monoklonal antikorlar sohasida keng qo'llaniladigan sarf materiallari. Hujayra madaniyati muayyan muhitni talab qiladi, uning sterilligi asosiy talab hisoblanadi. Xo'sh, hujayra zavodi bepushtlik talablariga qanday erishadi?
Hujayra madaniyatining bepushtligi uning o'sish muhitida hujayralarning o'sishi va ko'payishiga ta'sir qiladigan boshqa mikroorganizmlarning mavjudligini bildiradi. Bunday talablarni qondirish uchun hujayra zavodlari kabi sarf materiallari ham steril bo'lishi kerak. Avvalo, ushbu sarf materiallari ishlab chiqarish muhitining sterilligini ta'minlash uchun toza ustaxonada ishlab chiqariladi. Ikkinchidan, hujayra zavodini ishlab chiqarish tugallangandan so'ng, sterillik talablariga javob beradigan elektron nurli sterilizatsiya bilan ishlov beriladi.
Elektron nurni o'ldiradigan biologik bakteriyalar texnologiyasi sterilizatsiya qilish uchun beta-nurli nurlanishni qo'llaydigan sterilizatsiya texnologiyasidir. Bu elektron tezlatgich tomonidan hosil qilingan 3MeV-5MeV (million elektron volt) energiyaga ega bo'lgan yuqori tezlikdagi elektron nurlar yordamida mikroorganizmlarni o'ldirish usulidir. Elektron nurlar to‘g‘ridan-to‘g‘ri hujayra yadrosining DNK siga ta’sir qiladi, DNK molekulyar bog‘larini uzadi yoki hujayradagi suv bilan kimyoviy reaksiyaga kirishib, faol holat hosil qiladi va hujayradagi makromolekulalar ta’sirida reproduktiv to‘siq hosil qiladi. U bir martalik ishlatiladigan tibbiy va sanitariya buyumlari, oziq-ovqat, uy hayvonlari uchun ozuqalar, o'yinchoqlar va boshqalarni sterilizatsiya qilish uchun ishlatilishi mumkin.
Sterillik hujayra madaniyatining asosiy sharti bo'lsa-da, hujayra zavodi dan foydalanish jarayonida, shuningdek, zarur. yaxshi hujayra madaniyati natijalariga erishish uchun belgilangan tartib-qoidalarga rioya qiling.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
