Qizamiqga qarshi vaktsina emlashdan keyin qizamiq virusi, parotit virusi va qizilcha virusiga qarshi immunitetni rag'batlantiradigan kombinatsiyalangan jonli zaiflashtirilgan vaktsinadir. Qizamiq, parotit va qizilcha kasalliklarining oldini olish uchun ishlatiladi. Ushbu vaksinani keng miqyosda ishlab chiqarishda hujayra fabrikasi ajralmas hujayra madaniyati iste'mol qilinadi.
Qizamiqga qarshi vaktsina tovuq embrion hujayralarini mos ravishda qizamiq virusi va attenuatsiyalangan parotit virusi shtammlari bilan emlashdan iborat. va qizilcha virusining zaiflashtirilgan shtammlari bilan inson diploid hujayralarini emlash. Tegishli stabilizator qo'shing va muzlatib quriting. Bu pishloq rangidagi bo'shashmasdan tanasi bo'lib, u to'q sariq-qizil yoki och pushti rangda tiniq suyuqlikdir. Lioprotektorning asosiy komponentlari inson albumini, jelatin va saxaroza hisoblanadi.
So'nggi ikki yil ichida mening mamlakatimda qizamiq bilan kasallanish pasayish tendentsiyasini ko'rsatdi. 2019-yilda mening yurtimda qizamiq bilan kasallanganlar soni 2974 nafarni, vafot etganlar soni 0 nafarni tashkil etdi, kasallanish darajasi esa 0,21/100 ming nafarga kamaydi. 2020-yilda mening mamlakatimizda qizamiq bilan kasallanganlarning umumiy soni 856 nafarni, vafot etganlar soni 0 nafarni tashkil etdi, kasallanish darajasi esa 0,061/100 000 ga kamaydi. Vaktsina yaxshi profilaktik ta'sir ko'rsatdi. MMR vaktsinasini keng miqyosda ishlab chiqarish asosan 40 qatlamli hujayra zavodidan foydalanadi. Qatlamlar qancha ko'p bo'lsa, emlash mumkin bo'lgan hujayralar shunchalik ko'p. Qatlamlar soni juda ko'p bo'lgani uchun uni ishlatish qiyin. Odatda, suyuqlik bilan oziqlantirish, hujayralarni aralashtirish va kultura paytida suyuqlikni tushirish kabi operatsiyalar avtomatlashtirilgan chayqatish vositasi yordamida amalga oshiriladi, bu ham inson omillari sabab bo'lgan xatolarni kamaytirishi mumkin.
Hujayra zavodlari keng miqyosli hujayra madaniyati uchun ishlatiladigan sarf materiallari hisoblanadi. . Idishdagi qatlamlar sonini ko'paytirish orqali madaniyat maydoni kengaytirilishi mumkin va u biologik mahsulotlarni tayyorlashda muhim rol o'ynaydi.
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.
