Hujayra fabrikalariasosan farmatsevtika, vaktsina ishlab chiqarish, hujayra terapiyasi va boshqa sohalarda qo'llaniladigan keng ko'lamli hujayra madaniyatida muhim o'rin egallaydi. Hujayralar ishlab chiqarish muhitiga nisbatan sezgirroqdir, shuning uchun sarf materiallariga qo'yiladigan talablar ham nisbatan yuqori. Biologik aniqlash juda muhim asosiy aniqlash boʻlib, asosan quyidagi elementlarni oʻz ichiga oladi:
Sitotoksisite testi: Hujayra oʻlim mexanizmlari sifatida apoptoz yoki nekrozga tayanmaydigan hujayralar yoki kimyoviy moddalar natijasida kelib chiqqan sof hujayralarni oʻldirish hodisalari. Ushbu test orqali hujayra zavodining xom ashyosida hujayra o'sishiga yordam bermaydigan moddalar bor yoki yo'qligini aniqlash mumkin.
Sezuvchanlik testi: kimyoviy sensibilizatorlar organizmga turli yo'llar bilan ta'sir qiladi va organizmda immunitet hujayralarini hosil qilishi mumkin. ularga maxsus immun javoblarni hosil qiladi. aniq alomatlar va belgilarni ko'rsatadigan zarar. Ushbu test orqali tekshirilayotgan moddaning allergen ekanligini va sensibilizatsiya intensivligini aniqlash mumkin.
Gemoliz testi: Gemoliz testi milliy standartda belgilangan bakteriyalarni skrining va identifikatsiyalash usulidir. Odatda streptokokklar, vibrionlar, difteriya va boshqalarni aniqlashda foydalaniladi. Ko‘pgina bakteriyalar gemolizin ishlab chiqarishi mumkin, bu esa plastinkani gemoliz qilishi mumkin, shuning uchun bu bakteriyalar atrofida gemolitik halqa paydo bo‘ladi.
Tizimli toksiklik testi: tizimli toksiklik testining boshlang‘ich nuqtasi tibbiy asbobdan foydalanish paytida mahsulotning mumkin bo'lgan salbiy ta'sirini yoki uning materialini yuvishni hisobga olishdir. Chunki bu ekstraktlar mahsulot bilan bevosita aloqada bo'lmagan to'qimalar yoki organlarga inson tanasining so'rilishi, tarqalishi va metabolizmi orqali zarar etkazishi mumkin.
Bundan tashqari, biologik test shuningdek, intradermal stimulyatsiya testini va intradermal reaktsiya testini ham o'z ichiga oladi. Ushbu test elementlarining barchasi hujayra zavodida hujayra o'sishiga ta'sir qiluvchi moddalarni o'z ichiga olmaydi, shuning uchun hujayralarning normal ko'payishini ta'minlaydi.
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.
