The effects of radiation on their immunological functions and membrane damage were studied. The non-specific cytotoxicity and specific phagocytosis of AM irradiated with dose of 0, 100, 300 and 500 Gy decreased with the increase in dose. The relative fractions of Lactate Dehydrogenase and Beta-glucuronidase (β-glu) activity in supernatant increased with the increase in dose. There was a correlation between the suppression of immunological functions and the degree of damage of cytoplasmic and lysosomal membranes of AM after irradiation. Na2SeO3, a protective agent of cell membranes, alleviated this effect on the suppressive cytotoxicity indices of irradiated AM.展开更多

Similar to group of antibiotic and herbal medicine, fermented herbal medicine was additived to basic diet in four trials with eight replications per trial, determining effect on the growth performance, biochemical and immunological indicators. Compared with the control group, the group of fermented herbal compound had higher Average Daily Gain(ADG), higher content of immune globulin M(IgM) and immune globulin A(Ig A)(p〈0.05). There was no significant effect on the indicators of ADG, Average Daily Feed Intake(ADFI) and diarrhea rate(p〉0.05) between groups of antibiotic and fermented herbal were observed; however, the concentrations of Total Protein(TP), Growth Hormone(GH), IgG, IgM and IgA significantly increased(p〈0.05) compared with the control group.展开更多

Methods: Twenty five male Wistar rats of SPF grade were randomly divided into 5 groups: normal group, model group, Xiaoyao Powder (逍遥散) group, Gong-tone group and combined group (the combination of Gong-tone and Xiaoyao Powder), with 5 rats in each group. The rat model for the Chinese medicine syndrome of LSSD was induced by chronic bandage and irregular diet. The course of treatment was 21 days. After the treatment, the levels of serum gastrin and IgG were detected by enzyme-linked immunoabsorbent assay (ELISA). Phagocytosis of macrophages was detected by the neutral red uptake assay and T cell proliferation was investigated by 3-(4,5-dimethylthiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. Results: The serum gastrin, macrophage phagocytosis, IgG level and proliferation ability of T cells in the model group were significantly decreased compared with those in the normal group (P〈0.05). Compared with those in the model group, the serum levels of gastrin, macrophage phagocytosis, IgG level and proliferation ability of T cells in Gong-tone, Xiaoyao Powder, and combined groups were significantly increased (P〈0.05). The combined group was superior to either Gong-tone group or Xiaoyao Powder group. Conclusion: Gong-tone music may upregulate the immunological function and play a role in adjuvant therapy in the Chinese syndrome of LSSD.展开更多

The results were as follows: In acupuncture group,NK cell activity and T-lymphocyte positive rate of acid a-naphthyl acetate esterase (ANAE) and lymphocytetransformation rate were all increased. Compared with the control group, there was a significant difference( P < 0. 01 ) . The difference was insignificant when compared with normal group ( P >0 . 05) . Comparing thepathology grading of acupuncture group with control group, it showed marked difference in pathological sec-tion ( P< 0 . 01 ) . Adenoid structure and the degree of lymphocytic infiltration also have marked difference be-tween acupuncture and control group ( P < 0. 05 ) . Less tumour volume in acupuncture group than in controlgroup were observed ( P< 0. 01 ) . This indicated that acupuncture might increase the immunologic function oftransplanted mammary cancer in mice and inhibit the growth of mammary cancer and enhance both differentia-tion level of mammary cancer cells and lymphocytic infiltration. Possibly acupuncture might reduce the malig-nancy of mammary cancer cells.展开更多
文摘Alveolar macrophages (AM) from BCG activated Wistar rat were irradiated with different doses of Gamma rays in vitro. The effects of radiation on their immunological functions and membrane damage were studied. The non-specific cytotoxicity and specific phagocytosis of AM irradiated with dose of 0, 100, 300 and 500 Gy decreased with the increase in dose. The relative fractions of Lactate Dehydrogenase and Beta-glucuronidase (β-glu) activity in supernatant increased with the increase in dose. There was a correlation between the suppression of immunological functions and the degree of damage of cytoplasmic and lysosomal membranes of AM after irradiation. Na2SeO3, a protective agent of cell membranes, alleviated this effect on the suppressive cytotoxicity indices of irradiated AM.

文摘The surgical treatment methods for cirrhosis patients complicated with portal hypertension are complicated.In this study,we evaluated the effectiveness of a new treatment strategy:splenic auto-transplantation and oesophageal transection anastomosis on 274 patients from three aspects:clinical observation,splenic immunology and portal dynamics.From 1979 to 2005,274 cirrhosis patients with portal hypertension who underwent the new treatment strategy were followed up to observe different clinical indexes,which were then compared with those of the traditional surgery treatment.From 1999 to 2002,a randomized control trial(RCT)was performed on 40 patients to compare their immune function after operation.From 1994 to 2004,another RCT was carried out on 28 patients to compare the portal dynamics through three-dimensional dynamic contrast enhanced MR angiography(3D DEC MRA)investigation after operation.Among 274 patients(mean age 41.8 years),the emergency operative mortality(4.4%),selective operative mortality(2.2%),complication rate(17.9%),morbidity of hepatic encephalopathy(<1%),bleeding rate of portal hypertension gastritis(PHG)(9.1%),and morbidity of hepatic carcinoma(8%)were similar to those under traditional operation;the spleen immunology function(Tuftsin,IgM)decreased among the groups 2 months after operation.Through 3D DCE MRA,the cross section area,the velocity and volume of blood flow of main portal vein decrease significantly after operation in both groups,the auto transplantation group was significantly lower in velocity and volume of blood flow than in the control group.Splenic auto transplantation and esophageal transection anastomosis are a safe,effective,and reasonable treatment strategy for portal hypertension with varicial bleeding.It can not only correct hypersplenism but also completely stanch blood,and auto transplanted spleen in the retroperitoneal space can preserve immune function and establish abroad collateral circulation.
文摘This experiment mainly describes the effects of acupuncture on immunologic function andhistopathology of transplanted mammary cancer in mice. The results were as follows: In acupuncture group,NK cell activity and T-lymphocyte positive rate of acid a-naphthyl acetate esterase (ANAE) and lymphocytetransformation rate were all increased. Compared with the control group, there was a significant difference( P < 0. 01 ) . The difference was insignificant when compared with normal group ( P >0 . 05) . Comparing thepathology grading of acupuncture group with control group, it showed marked difference in pathological sec-tion ( P< 0 . 01 ) . Adenoid structure and the degree of lymphocytic infiltration also have marked difference be-tween acupuncture and control group ( P < 0. 05 ) . Less tumour volume in acupuncture group than in controlgroup were observed ( P< 0. 01 ) . This indicated that acupuncture might increase the immunologic function oftransplanted mammary cancer in mice and inhibit the growth of mammary cancer and enhance both differentia-tion level of mammary cancer cells and lymphocytic infiltration. Possibly acupuncture might reduce the malig-nancy of mammary cancer cells.
