Hujayra madaniyati jarayonida noto'g'ri ishlash va boshqa sabablarga ko'ra yuzaga keladigan turli ifloslanish muammolari doimo tadqiqotchilarning diqqat markazida bo'lib kelgan. Ayniqsa, hujayra fabrikalari kabi keng miqyosli hujayra madaniyatida hujayraning ifloslanishi muammosini e'tibordan chetda qoldirib bo'lmaydi.
Aslida hujayra madaniyati uchun hujayra zavodlaridan foydalanganda, agar barcha ishlar joyida bajarilsa va oldini olish bo'yicha xabardorlik o'rnatiladi, ko'plab ifloslanishlarning oldini olish mumkin. Xususan, u quyidagi jihatlarni o'z ichiga oladi:
1. Yaxshi qoidalar va qoidalar: Hujayra madaniyati hududida qat'iy qoidalar va qoidalar o'rnatilishi kerak va faqat tegishli xodimlar kirishi mumkin. Kerakli narsalar yaqin joyda joylashtirilishi va hujayralar bilan ishlashda keraksiz harakatlarning oldini olish uchun uni oqilona tartibga solish kerak.
2. Aseptik operatsiya: Bu hujayra madaniyati jarayonida juda muhim nuqta, shu jumladan madaniyat muhitini tayyorlash, suyuqlik quyi qadoqlash, material bilan ishlash, suyuqlikni nafas olish yoki aspiratsiya qilishda qanday ishlash kerakligi va hokazo, bularning barchasi qat'iy bajarilishi kerak. bepushtlik tamoyiliga muvofiq.
3. Ish joyini toza tuting: hujayra madaniyati atrof-muhitga nisbatan juda yuqori talablarga ega va ish joyini muntazam ravishda toza saqlash kerak, bu erda pollar va stol usti, karbonat angidrid inkubatorlari, biologik xavfsizlik shkaflari, chiqindilar, suv hammomlari va boshqalar.
4. Antibiotiklardan oqilona foydalanish: Antibiotiklar hujayralar ifloslanishini kamaytirishi mumkin, ammo haddan tashqari ishonish aseptik operatsiyalarni e'tiborsiz qoldirishga intiladi va antibiotiklardan foydalanish ham hujayralarning biologik xususiyatlarini o'zgartirishi va eksperimental natijalarni noto'g'ri yo'naltirishi mumkin, shuning uchun ularni ehtiyotkorlik bilan ishlatish kerak.
5. Hujayra bankini tashkil qilish: Shartli muassasalar o'zlarining hujayra banklarini yaratishlari kerak va kriosaqlangan hujayralarning biologik xususiyatlari o'zgarmaydi, bu yashirin ifloslanishning potentsial zararini bartaraf etishi mumkin.
Hujayralarning ifloslanishi ularning o'sishi va ko'payishiga ta'sir qiladi va bular hujayralar odatda tashlanadi. Yuqoridagi fikrlarni bajarish hujayra zavodidagi hujayralarning ifloslanishini oldini oladi va tajribaning rivojlanishini 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.
