Sensibilizatsiya testi - bu tekshirilayotgan moddaning allergen ekanligini va sezgirlik intensivligini aniqlash uchun test. Keng miqyosli hujayra yoki to'qima madaniyatida keng qo'llaniladigan hujayra sarfi sifatida Sensibilizatsiya sinovi hayvonlari asosan gvineya cho'chqalari, sinov moddalari esa asosan sof kimyoviy mahsulotlardir. Qo'llaniladigan doz tizimli toksiklik yoki mahalliy tirnash xususiyati belgilarini keltirib chiqarmaydigan maksimal dozadan boshlab eksperimental tarzda aniqlanadi. EHMlar soni bir yoki bir nechta bo'lishi mumkin. Cheklov testi oxirgi sensibilizatsiya ta'siridan 2-4 hafta o'tgach amalga oshiriladi va sensibilizatsiya mavjudligi yoki yo'qligi va sensibilizatsiya intensivligi mahalliy yoki tizimli reaktsiyalarga ko'ra aniqlanadi. shuningdek, allergenlarni o'z ichiga olganligini va sezgirlik kuchini aniqlash uchun sensibilizatsiya sinovlaridan o'tkazilishi kerak. tananing antijenik yoki haptenik kimyoviy ta'sirga sezgirligi ortadi. Sensibilizatsiya qiluvchi ta'sirga ega bo'lgan kimyoviy moddalar kimyoviy allergenlar yoki kimyosensibilizatorlar deb ataladi. Kimyoviy sensibilizatorlar organizmga turli yo'llar bilan ta'sir ko'rsatadi va organizmdagi faol immunitetli hujayralar ularga o'ziga xos immunitet reaktsiyalarini ishlab chiqarishi mumkin. alomatlar va belgilar. Agar hujayra zavodida allergen bo'lsa, u hujayralarning o'sishi va ko'payishiga ta'sir qiladi.
Hujayra zavodining sensibilizatsiya testi orqali u mahsulot sifati malakali yoki yo'qligini aniqlash va keyingi hujayra madaniyati testining silliq o'tishini ta'minlash uchun kimyoviy allergenlarni o'z ichiga oladimi yoki yo'qligini aniqlash mumkin.
The sensitization test animals are mostly guinea pigs, and the test substances are mostly pure chemical products. The dose to be used is determined experimentally, starting with the maximum dose that does not produce symptoms of systemic toxicity or local irritation. The number of exposures can be one or more. The challenge test is carried out 2 to 4 weeks after the last sensitization exposure, and the presence or absence of sensitization and the intensity of sensitization are determined according to local or systemic reactions.
Through the sensitization test of the cell factory, it can be judged whether it contains chemical allergens, so as to identify whether the product quality is qualified or not, and to ensure the smooth progress of the later cell culture test.
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.
