[Biomass allometric equations of nine common tree species in an evergreen broadleaved forest of subtropical China].

Biomass allometric equation (BAE) considered as a simple and reliable method in the estimation of forest biomass and carbon was used widely. In China, numerous studies focused on the BAEs for coniferous forest and pure broadleaved forest, and generalized BAEs were frequently used to estimate the biomass and carbon of mixed broadleaved forest, although they could induce large uncertainty in the estimates. In this study, we developed the species-specific and generalized BAEs using biomass measurement for 9 common broadleaved trees (Castanopsis fargesii, C.

[Primary exploration on immune associated genome of patients with Pi-Qi deficiency syndrome].

Objective: To investigate the abnormal change of immune function in patients with Pi-Qi deficiency Syndrome, and to explore the genomic mechanism of its genesis by cDNA chip techniques.

Methods: The cross probe was made by extracting and microamplifying the total RNA and mRNA of peripheral white blood cells (WBC) in healthy subjects and patients with chronic gastritis and ulcerative colitis, which were labeled by Cy3 and Cy5 respectively. Then equal quantity of the two labeled probes were mixed and hybridized with cDNA chip, fluorescent signal of the chips were scanned with scanner.
