IM To investigate the effects of garlic on micronuclei frequency (MNF) of peripheral blood lymphocytes (PBL) in gastric carcinoma (GC) and precancerous lesion (PL) in Wistar rats induced by NmethylN′nitroNnitrosoguanidine (MNNG). METHODS Gastric carcinoma and precancerous lesions were induced by MNNG 125mg/5ml per day for 10 months. 10% garlic 10ml per day were given to the experimental group, and running water to control group. MNF of PBL in the control CG (n=16), MNNG (n=30), prevention (n=30) and treatment groups (n=20) were detected at 10 and 16 months by the technic of micronucleus cell culture. RESULTS MNF of MNNG group at the 10th and 16th month was similar; that of MNNG, GC and PL was remarkably higher than the control group (P<001), respectively; and that of PL was lower than GC (P<001). MNF of prevention and treatment groups was decreased, with significant difference from MNNG group (P<001). MNF of the prevention group at the 16th month was lower than that at the 10th month (P<001), the difference between the prevention and treatment groups was not significant. CONCLUSION MNNG was a continuous mutagenicity and carcinogenicity, and garlic has a remarkable antimutagenic and anticarcinogenic effect. The micronucleus frequency of PBL may be a new marker of earlystage gastric carcinogenesis. 展开更多

METHODS:... AIM: To investigate the features of various blood- borne virus infections and co-infection in intravenous drug users (IDUs), and to examine the correlation of T lymphocyte subsets with virus co-infection. METHODS: Four hundred and six IDUs without any clinical manifestation of hepatitis and 102 healthy persons were enrolled in this study. HBV-DNA and HCV-RNA were detected by fluorescence quantitative PCR. HBsAg, HBeAg, anti-HBc, anti-HCV, HDV-Ag, anti-HGV, anti-HIV, and HCMV-IgM were assayed by enzyme-linked immunosorbent assay (ELISA) and immunochromatographic tests. The levels of Th1 and Th2 cytokines were measured by ELISA and radioactive immune assay (RIA). The T lymphocyte subpopulation was detected by using fluorescence immunoassay. The similar indices taken from the healthy persons served as controls. RESULTS: The viral infection rate among IDUs was 36.45% for HBV, 69.7% for HCV, 47.3% for HIV, 2.22% for HDV, 1.97% for HGV, and 3.45% for HCMV. The co- infection rate of blood-borne virus was detected in 255 of 406 (62.81%) IDUs. More than 80% (161/192) of subjects infected with HIV were co-infected with the other viruses, such as HBV, HCV. In contrast, among the controls, the infection rate was 17.65% for HBV and 0% for the other viruses. Our investigation showed that there was a profound decrease in the proportion of CD4/CD8 and the percentage of CD3 and CD4, but not in the percentage of CD8. The levels of PHA-induced cytokines (IFN-γ and IL-4) and serum IL-2 were obviously decreased in IDUs. On the other hand, the level of serum IL-4 was increased. The level of IFN-γ and the percentage of CD4 were continuously decreased when the IDUs were infected with HIV or HIV co-infection. IDUs with HIV and HBV co-infection was 15.1% (29/192). Of those 29 IDU with HIV and HBV co-infection, 51.72% (15/29) and 37.93% (11/29) were HBV-DNA-positive and HBeAg-positive, respectively. But, among IDUs without HIV infection, only 1.68% (2/119) of cases were HBV- DNA-positive.CONCLUSION: HCV, HBV and HIV infections are common in this population of IDU, leading to a high incidence of impaired Thl cytokine levels and CD4 lymphocyte. IDUs with HIV and HBV/HCV co-infection have lower expression of Th1 cytokine with enhancement of the Th2 response. HIV may be causing HBV replication by decreasing Thl function. 展开更多

Tumor infiltrating lymphocytes (TIL) were cultured with “moxibustion serum”(MS), and the results were examined by flow cytometry. The results indicated that MS could enhance the proliferation of TIL,accelerate it to reach the exponential growth phase, and assist recombinant interleukin 2 (rIL-2) to enhance successively the percentage of CD3^+ positive cells, maintain the number of CD4^+ positive T cells, promote greatly the percentage of CD8^+ positive T cells among TILs, and reverse the CD4^+/CD8^+ ratio. Such cooperative effects rely on relative specificity of acupoints. It is suggested that MS is beneficial to the growth of TIL both in the aspects of proliferation and phenotypes. 展开更多

In the twenty first century research works, there may be a need to achieve a more reliable research result through a synergy between engineers and biological researchers. The peak absorbance data for various interacting systems were measured. These were used to show that the antiretroviral drug has the effect of increasing the peak absorbance values of both the uninfected and infected blood components, i.e., the drugs are made able to increase the light absorption capacity of the blood cells. For drug 2 that contains three components including Efavirenz, the drug effect on lymphocytes was increased by about 38% for patients that had been on antiretroviral drug treatment. Mathematical models were proposed and used in determining the coating effectiveness of antiretroviral drugs in the presence and absence of HIV. The use of the findings of this work by pharmaceutical industries may help in the search for more effective antiretroviral drugs for the treatment of HIV patients. 展开更多

Objective: To analysis the uptake of free MTX and MTX conjugated to tumor specific monoclonal antibody by target and nontarget cells. Methods: The folate antagonist methotrexate (MTX) was conjugated to two monoclonal antibodies (Mab) directed against human chronic lymphocytic leukemia (CLL), Dal B01 and Dal B02, by an active ester method. Both conjugates were more cytotoxic toward the target tumor cell line D101 than to the nontarget cell line MOLT3, and Dal B02MTX conjugate was more inhibitory to D101 cells than free MTX in a 6 h pulse exposure assay. Results: Drug uptake studies revealed that D101 cells took up much more Dal B01 and Dal B02conjugated MTX than free MTX. The amounts of drug taken up by D101 cells incubated with Dal B01 and Dal B02conjugated MTX were always 3 to 5fold higher than that taken up by MOLT3 cells, although the latter took up more drug when incubated with free MTX. Furthermore, tumor cells incubated with Dal B01 or Dal B02conjugated MTX retained much larger amounts of drug for a prolonged period of time than those incubated with free MTX. Conclusion: The enhanced specific cytotoxicity of Dal B01 and Dal B02MTX conjugates toward target tumor cells is therefore likely due to (I) delivery of larger amounts of MTX to target cells when the drug is conjugated to Mab; (ii) longer retention of Mabconjugated MTX by target cells; and (iii) slow, prolonged release of MTX from the surfacebound or endocytosed conjugates, rendering them into a sustained release dosage form. 展开更多

Hamaker coefficient approach was used as a surface thermodynamic tool in determining the HIV- blood interactions in the antiretroviral drug environment. The methodology involved the absorbance measurement using a digital Ultraviolet Visible MetaSpecAE1405031Pro Spectrophotometer of blood samples collected from ten HIV infected persons who had not commenced treatment with antiretroviral drugs (No ARV), ten HIV infected persons who had already commenced treatment with antiretroviral drugs (with ARV) and ten blood samples of uninfected persons all in each of five different antiretroviral drugs environment. The variables required for the computations with the Lifshiftz formula in the determination of Hamaker constants/coefficients were derived from the absorbance data. The values of the various Hamaker coefficients for each antiretroviral drug on both infected and uninfected blood samples were calculated. MATLAB software tools were employed in the computations. The absolute values for the combined Hamaker coefficient for the drugs ranged from -0.02481 × 10-21 Joule for drug 4 to -0.05845 × 10-21 Joule for drug 3. The negative senses of the absolute combined Hamaker coefficient imply net negative van der Waals forces indicating a possible repulsion between HIV and drug coated lymphocyte cells. For the virus interacting with blood samples not coated with the drugs, the Hamaker coefficients are positive indicating the vulnerability of the lymphocytes in the absence of the drugs. This effect suggests effective coating or binding of the lymphocytes with the drugs is needed for possible blocking of the virus from the surface of the lymphocyte cell. A thermodynamic criterion for HIV-drug interaction prediction was suggested and found to be a valuable tool in HIV-blood interaction study. The use of the findings of this work by pharmaceutical industries may be possible in the area of drug design. 展开更多

Objective: To explore the prognostic factors for very severe aplastic anemia (VSAA) patients treated mainly with Chinese Kidney (Shen)-invigorating drugs (CKID) combined with anti-lymphocyte globulin (ALG) or anti-thymocyte globulin (ATG). Methods: Twenty-seven VSAh. patients were treated with CSID+ALG/ ATG therapy in conjunction with cyclosporine A, androgen, hemopoietic growth factor, etc. The relationship of the effectiveness and some factors (age of patients, course of illness, blood and bone marrow figures, etc.) were analyzed. Results: In the 25 evaluated VSAA patients who had been followed up for over 1 year, 9 patients (36.0%) were basically cured, 5 (20.0%) remitted, 6 (24.0%) were markedly improved, and 5 (20.0%) were treated in vain, with the total effective rate of treatment being 80.0% (20/25). Better clinical therapeutic effects were shown in patients newly diagnosed with VSAA, of male sex (P=0.037), 〉20 years old (P=0.045), with an illness course ≤ 1 month (,P=0.048), with peripheral neutrophil count 〉0.1 × 10^9/L (P=0.023), and with reticulocyte count 〉10 × 10^9/L (P=0.002). Platelet count (P=0.620) and bone marrow lymphocyte percentage (P=0.736) showed no correlation with the therapeutic effectiveness. Multi-factor analysis by the Kaplan-Meier procedure on the factors influencing survival showed that rather longer survival times occurred in patients 〉 20 years old, with peripheral neutrophil count ≤〈0.1 × 10^9/L, reticulocyte count ≤10 × 10^9/L, and platelet count 〉 10 × 10^9/L (allP=0.0001). Bone marrow lymphocyte percentage and the initiation time of ALG/ATG application (from onset of the illness) showed no significant influence on patients' survival time (P=0.085 and P=0.935, respectively). Conclusions: CSKD+ALG/ATG therapy for treatment of VSAA could enhance the current clinical therapeutic effects and elevate patients' survival rate. Conditions including male sex, age 〉20 years, illness course ≤1 month, neutrophil count 〉0.1× 10^9/L, and reticulocyte count 〉10 × 10^9/L are the likely effective indices for predicting favorable therapeutic effectiveness in newly diagnosed VSAA patients. 展开更多
