提高集成材出材率的措施

集成材生产是木材综合利用的有效途径,是木材加工业的重要组成部分,我国集成材生产中普遍存在出材率低、成本高、影响经济效益等问题,结合我国集成材生产实践,提出几点提高集成材出材率的措施。     

Flow cytometry: An aid in monitoring lymphocyte transformation in whole blood cultures

A combination of whole blood cultures, hypotonic fluorescent staining of nucleated cells, and flow cytometry resulted in a greatly improved technique for measuring lymphocyte blastogenesis. Sample preparation was reduced to two steps with no centrifugation. The technique was successfully used to analyze blood cultures derived from experimentally and naturally infected cows. The technique was also shown to be ideally suited for analyzing lymphocytes cultured in whole blood cultures and (1) avoids the problems of tritiated thymidine analysis and (2) provides a direct analysis of the number of cells responding to antigenic stimulation.
