control sum
2.Same condition was found between the experimental and the control, (2) The sum total of the bacteria, rod-shaped bacteria, and spirochetes were decreased in the liquid of gingivd groove after the 0.1% CTP toothpaste being used in periodontitis patients(P<0. 01). Also the ratio of rod-shaped bacteria to spirochetes was decreased(P<0. 01). The results showed that CTP can prevent and treat periodintits.
4.With DNase I as a probe, the sensitivity of chromatin of these two tissue cells to DNase I was determined. It was observed that there was no apparent difference between the regenerating liver and the sham operation control liver, suggesting that the sum of the sites of active transcription in chromatin of the two cell types remained unchanged;
7.Quality requirements, cost control, progress schedule and execution supervision that the owner demands can be reflected in the lump-sum contract.
