OBJECTIVETo investigate the effect of Kangning granules on inflammatory and immunology.
METHODPedal swelling induced by 1% agar in mice, dermal capillary hyper-permeability induced by histamine in rats were used to evaluate the anti-inflammatory of Kangning granules, and the clearance rate of intravenous charcoal particles was used to study its effect on non-specific immunologic functions. Serum haemolysin level and the number of antibody secretory cells in spleen were determined to assess its effects of specific immunologic functions. MTT colored method was used to determine the effect of Kangning granules on T- or B-Lymphocytes proliferation.
RESULT5, 10, 20 g x kg(-1) of Kangning Granules significantly inhibited pedal swelling induced by agar in mice (P < 0.05, P < 0.01). 2.4, 4.8, 9.6 g x kg(-1) of Kangning Granules evidently decreased dermal capillary hyper-permeability induced by histamine in rats (P < 0.05, P < 0.01). 10, 20 g x kg(-1) of Kangning Granules enhanced the phagocytic function and phagocytosing velocity in mice (P < 0.05). 5, 10, 20 g x kg(-1) of Kangning Granules obviously increased serum haemolysin level and the number of antibody secretory cells in spleen (P < 0.05, P < 0.01). 20 g x kg(-1) of Kangning Granules promoted B-Lymphocytes proliferation (P < 0.05).
CONCLUSIONKangning granules significantly inhibited inflammatory reaction and increase immune functions in animals.

The present study aimed to determine the role of tissue injury in migration of mesenchymal stem cells (MSCs) intravenously transplanted into heart and to establish experimental basis for improving stem cell therapy in its targeting and effectiveness. MSCs were isolated from bone marrow of male Sprague-Dawley rats and purified by density centrifuge and adhered to the culture plate in vitro. Female rats were divided randomly into four groups. Myocardial ischemia (MI) transplanted group received MSCs infusion through tail vein 3 h after MI and compared with sham-operated group or normal group with MSCs infusion, or control group received culture medium infusion. MI was created in female rats by ligating the left anterior descending coronary artery. The heart was harvested 1 week and 8 weeks after transplantation. The characteristics of migration of MSCs to heart were detected with expression of sry gene of Y chromosome by using fluorescence in situ hybridization (FISH). Ultrastructural changes of the ischemic myocardium of the recipient rats were observed by transmission electron microscope (TEM). One week or 8 weeks after transplantation, sry positive cells were observed in the cardiac tissue in both of MI transplanted group and sham-operated group, the number of sry positive cells being significantly higher in MI transplanted group (P<0.01). No significant difference was found in the number of sry positive cells between 1 week and 8 weeks after transplantation. No sry positive cells were observed in the hearts of control and normal group. In addition, the ultrastructure of some cells located in the peri-infarct area of MI rats with MSCs transplantation was similar to that of MSCs cultured in vitro. These results indicate that MSCs are capable of migrating towards ischemic myocardium in vivo and the fastigium of migration might appear around 1 week after MI. The tissue injury and its degree play an important role in the migration of MSCs.
