Ifekthri yeseliubuchwepheshe bezamasiko buyindlela yesiko esetshenziswa kakhulu kumasiko amaningi amakhulu. Lapho uhlakulela amangqamuzana, uzothinteka yizici eziningi, ezivimbela ukukhula okuvamile nokukhiqizwa kwamaseli. Imisebe namaza e-ultrasonic angenye yawo.
Ukukhanya okubonakalayo: Ubude begagasi bokukhanya obubonakalayo bungu-390~780nm. Ukukhanya okumibalabala okuhlukahlukene kungabangela ukuwohloka kwamangqamuzana, kunwebe i-interphase yokuhlukaniswa kwe-nuclear, futhi kunciphise kakhulu amandla amaseli okunamathisela odongeni. Ngakho-ke, lapho usebenzisa imboni yamangqamuzana ukwenza isiko le-in vitro lamaseli, ukukhanya kwelanga okuqondile kufanele kugwenywe, futhi isiko kufanele senziwa ebumnyameni noma ligcinwe isikhathi esifushane ngangokunokwenzeka.
Imisebe ye-Ultraviolet: Amaseli ebekezelela kakhulu imisebe ye-UV ebuthakathaka ayishintshi kakhulu, kodwa amaseli azwelayo alimele. Lapho imisebe ye-ultraviolet inamandla, amangqamuzana angawodwa abonisa ukuthi: i-mitosis ephelele ayikwazi ukwenziwa; i-syneresis yanda ngesikhathi se-mitosis; I-cytoplasmic blebbing iyancipha ngesikhathi se-mitosis. Amabhamuza akheka endaweni enomsebe, kulandele ukwanda kwamaseli kanye nokulimala okwengeziwe.
Ukukhishwa kwemisebe: I-X-ray inomonakalo osobala kumaseli, ama-B-ray angaphazamisa ukuhlukana kwe-nucleus, futhi ama-R-ray anciphisa isibalo sokuhlukana kwe-nuclear futhi kubangele ukuhlukana kwenuzi okungavamile, okungabangela ukufa kwamangqamuzana.
Ultrasound: Ngaphansi kokudlidliza kwe-ultrasonic, amaseli azophuka maduze, futhi i-cytoplasm izogeleza ngokuphazamiseka ekuqaleni, futhi ukwakheka kwe-colloidal ye-protoplasm nakho kuzoshintsha kakhulu. Uma ukudlidliza kwe-ultrasonic kumisiwe, kungabuyiselwa. Isizathu sokufa kweseli kungenxa ye-cavitation. Uma igagasi le-ultrasonic liku-2.5W/cm2, amaseli alimele futhi ama-chromosome awashintshile. Ama-chromosome enyukliya awokuqala ukuhlanekezelwa.
Ukukhishwa kwemisebe kanye namagagasi e-ultrasonic yizici ezibalulekile lapho kusetshenziswa izimboni zamaseli ukwenza isiko lamaseli. Ngaphezu kwalokho, izici ezifana nezinga lokushisa, ingcindezi ye-osmotic, kanye nenani le-pH nakho kuzothinta ukukhula nokukhiqizwa kwamaseli. Ukulawula lezi zici kungaqinisekisa ukukhula kwamaseli okuvamile.
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.
