Microbial production of 5-aminolevulinic acid (5-ALA) by photosynthetic bacteria compared to other bacteria and algae was reviewed. During anaerobic cultivation of the Rhodobacter spaeroides mutant strain, control of the redox potential was effective or producing large amounts of extracellular ALA. ALA has been practically applied in agriculture as herbicide, pesticide and growth-promoting factor for plants. New agriculture applications including salt tolerance and cold temperature tolerance of plants were also desired. Finally recent medical application for cancer treatment, tumor diagnosis and other clinical uses were discussed.

Objective To elucidate the effect of human leukocyte antigen(HLA)cross-reactive groups(CREGs)matching on the patient/graft survival rate of renal transplant recipients positive for penal-reactive antibody(PRA).Methods The PRA level and the HLA antibody specificity of renal transplant candidates were assayed using the LAT1240,LM720R,and SSP2LB kits.The appropriate donors were selected according to the CREGs matching standard.Results 112 recipients included 43 positive cases of HLA classⅠantibody,39 positive cases of HLA classⅡantibody,and 30 positive cases of bothⅠandⅡ.The HLA mismatching cases of 0,1,2,3,4 and 5 allele(s)were 6,39,38, 21,7 and 1,respectively.Hyper-acute rejection(2 cases),acute rejection(18 cases),chronic rejec- tion(5 cases),delayed graft function(4 cases),graft excision(one case)due to rejection and deaths (13 cases,5 with a functioning graft)occurred after transplant.Ninety-nine recipients and 96 grafts survived.The 1-,3-,and 5-year graft survival rate was 91.96%,86.96%,and 86.21%,respec- tively.Conclusion The HLA matching rate of patient/graft was elevated significantly and the effect of high PRA level was decreased according to the principle of CREGs,which increased the patient/graft survival rate remarkably in sensitized recipients.

The microstructure of cationic cyclopeptide (TD-34) treated Caco-2 cell membrane was observed, and we discussed the relationship between membrane structure and insulin transmembrane permeability. Atomic force microscope (AFM) was used to observe living cell membrane in air condition and tapping mode. Results showed that the surface of Caco-2 cell membrane treated with TD-34 lost its smoothness and nearly doubled its roughness. Apparent permeability coefficients (P(app)) of insulin in Caco-2 cell monolayers increased 2.5 times. In conclusion, AFM can be used to observe microstructure of cationic cyclopeptide treated cell membrane and cationic cyclopeptide enhanced insulin delivery across Caco-2 cell membrane by increasing membrane fluidity.
