Mast cells (MCs) play a key role in the pat hogenesis of allergic diseases. Tissue MCs are originated from hematopoietic ste m cells in bone marrow. In recent years, it was reported that human mast cells c ould be differentiated from stem cells of umbilical cord blood. In this review, we summarize the development in this novel area.
5.Induction of monocyte chemoattractant protein-1 secretion from lung epithelial cells by trypsin
Chinese Journal of Pathophysiology 1986;0(04):-
AIM: To investigate the actions of trypsi n on the secretion of monocyte chemoattractant protein-1 (MCP-1) from human lung e pithelial cells. METHODS: A549 cells were cultured in a 12-well culture plate. Th e challenge was performed by addition of various concentrations of trypsin or tr ypsin inhibitor into each well, respectively. After 2 h, 8 h or 16 h, the reacti ons were terminated by removal of the supernatant from each well. A sandwich ELI SA was used to determine the levels of MCP-1 in supernatants. RESULTS: Following 16 h incubation, trypsin was able to induce c oncentration-dependent secretion of MCP-1. As low as 3 ?g/L trypsin was able to induce MCP-1 release from epithelial cells, and the maximum of accumulated rele ase of MCP-1 was observed with 100 ?g/L trypsin, which was 3 fold more than bas eline release. However, trypsin at 300 ?g/L did not induce significant MCP-1 se cretion. Soybean trypsin inhibitor (SBTI) inhibited trypsin-induced MCP-1 secret ion, but ? 1-antitrysin (? 1-AT) did not. The time course showed that the actions of trypsin initiated at 2 h and reached their peak at 16 h. CONCLUSION: Trypsin is a potent secretogogue of MCP-1 release fr om cultured human lung epithelial cells, and itself action can be inhibited by S BTI.

Objective: To compare the different therapeutic effects of acupuncture and Phenolphthalein for constipation due to intestinal qi stagnation. Methods:A total of 50 patients with constipation due to intestinal qi stagnation were randomly divided into an acupuncture group and a medication group by the random digital table, 25 cases in each group. The patients in the acupuncture group were treated by puncturing Gongsun (SP 4), Sanyinjiao (SP 6), Taichong (LR 3), Zusanli (ST 36), Shangjuxu (ST 37), Hegu (LI 4), Lieque (LU 7), and Tianshu (ST 25), once every day, and 7 d as one course, for continuous 3 courses; while the patients in the medication group were given Phenolphthalein, 7 d as one course, for continuous 3 courses. Compared the Cleveland clinic constipation score (CCS) between the two groups after one course, 3 courses and 3 months after the treatment, as well as the frequency of defecation within one week. Results:After one week of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the medication group than in those of the acupuncture group (P<0.01). After 3 weeks of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significant in the patients of the acupuncture group than in those of the medication group (P<0.05). Three months after the end of treatment, CCS scores and frequency of defecation per week were significantly changed in both groups compared with those before treatment (P<0.05), and CCS scores and frequency of defecation per week were improved more significantly in the patients of the acupuncture group than in those of the medication group (P<0.05). Conclusion:Acupuncture and medication are effective in the treatment of constipation due to intestinal qi stagnation. Their short-term therapeutic effect is similar, but the long-term therapeutic effect is better in the acupuncture group than in the medication group.

In this paper, a new imaging method to determine the position of blood effusions or edemas in the deep position of the brain by using electric current flowing through the brain is presented. Its principle is that the existence of non-normal matters in the brain cause a disturbance to boundary potentials, while a low frenqency current flows through the brain. In terms of the measurement for the change value of boundary potentials a reconstruction for the blood effusion or the edema in the deep position of the brain can be done.
