Effect of Excessive Iodine on Immune Function of Lymphocytes and Intervention with Selenium

In order to study the effect of excessive iodine on immune function of lymphocytes and the role of selenium supplementation with excessive iodine intake, the changes of T lymphocyte number, ratio of subsets, activity of natural killer （NK） cells and lymphocytes proliferation response were investigated. 150 female BALB/C mice were randomly divided into 5 groups in terms of their body weight （n=30 in each group）, and 10 of each group were taken as one batch for test. Mice in the 5 groups were orally administrated with iodine 0 （group Ⅰ ）, 1500 （group Ⅱ）, 3000 （group Ⅲ）, 6000 μg/L （group ）, iodine 6000 μg/L plus selenium 0.3 mg/L （group Ⅴ） respectively for 30 days. Lymphocyte proliferation response, CD4^＋/CD8^＋, Th1/Th2 and the activity of NK cells were measured. CD4^＋/CD8^＋ was significantly lower, while lymphocyte proliferation response stronger, and Th1/Th2 and the activity of NK cells significantly higher in group Ⅳ than in group Ⅰ （P〈0.01）. There was no significant difference in all indexes between group Ⅴ and group Ⅰ （P〉0.05）. It was suggested that excessive iodine as exogenous chemical materials can induce disorders of T lymphocyte immune function in mice. 0.3 mg/L selenium supplementation can protect mice against toxicity induced by 6000 μg/L iodine.

Effects of Echinacea Compound on the Immune Function of Weaned Piglets

[Objective] This study aimed to investigate effects of Echinacea compound on the immune function of weaned piglets. [Method] Eighty Duroc x Landrace x Yorkshire crossbred piglets were randomly divided into four groups： control group （drug-free group）, 1.5% close group, 1.0% dose group and 0.5% dose group. Blood samples of piglets were collected at 20, 35, 50, 60, 70 and 80 days old, respective- ly, to determine neutrophil leukocyte percentage in peripheral blood, lymphocyte trapsformation rate and the levels of antibodies against classical swine fever, porcine reproductive and respiratory syndrome disorder. [Result] Applying a certain dose of Echinacea compound could significantly increase neutrophil leukocyte per- centage in peripheral blood and lymphocyte transformation rate （P〈0.05）, and ex- tremely significantly improve the levels of antibodies against classical swine fever, porcine reproductive and respiratory syndrome disorder （P〈0.01）. [Conclusion] Echi- nacea compound has played a certain role in promoting nonspecific and specific im- mune function of piglets.

Changes in count and function of splenic lymphocytes from patients with portal hypertension

AIM: To investigate changes in numbers and proliferative function of splenic lymphocytes in patients with hypersplenism due to portal hypertension (PH), to provide evidence for further study of immune status of the spleen during PH. METHODS: Twelve spleens from patients with hypersplenism due to PH served as the PH group, and four spleens from cases of traumatic spleen rupture were regarded as the control group. After weighing the spleen, lymphocytes were separated and counted using a cell counting plate to calculate the lymphocyte count per gram of spleen tissue (relative quantity) and total lymphocyte count in whole spleen (absolute quantity). The immunohistochemical SP method was used to observe the density and distribution of lymphocytes in the spleen. The MTT method was used to observe changes in lymphocyte proliferative function. RESULTS: As compared to the control group, the splenic lymphocytes in the PH group showed that: (1) There was no difference in distribution but a significant decreasein density; (2) the number of lymphocytes per gram of spleen (relative quantity) decreased significantly (0.822 ± 0.157) × 108 vs (1.174 ± 0.254) × 108, P < 0.01]; (3) with the significant increase in the weight of the PH spleen (832.6 ± 278.2 g vs 211.7 ± 85.6 g, P < 0.01), the total quantity of lymphocytes (absolute quantity) increased significantly (0.685 ± 0.072) × 1011 vs (0.366 ± 0.057) × 1011, P < 0.01]; and (4) the proliferative function of lymphocytes was enhanced: T lymphocytes, (0.022 ± 0.005 vs 0.015 ± 0.003, P < 0.05), and B lymphocytes (0.034 ± 0.006 vs 0.023 ± 0.001, P < 0.01). CONCLUSION: Although lymphocyte density in the spleen decreased in patients with PH, the total quantity of lymphocytes increased because spleen weight increased greatly, along with the proliferating function. With respect to changes in lymphocytes, PH spleens may still have immune function, although it may be disordered. However, complete evaluation of the immune function of the spleen in PH requires more research.

Effect of Early Intensive Insulin Therapy on Immune Function of Aged Patients with Severe Trauma

This study examined the effect of intensive insulin therapy on immune function and inflammatory factors at the early phase after severe trauma. At day 1, 3, 5, 7 after admission, subsets of CD4＋ helper T lymphocytes （Th1/Th2） and human leukocyte antigen （HLA）-DR expression on CD14＋ monocytes were flow cytometrically measured. Levels of cytokines, including tumor necrosis factor-alpha （TNF-α）, interleukin-6 （IL-6）, interleukin-10 （IL-10） and other immunity markers, such as IgA, IgG, IgM, C3, C4 and C reaction protein （CRP） were examined in two groups. The results showed that TNF-α, IL-6 and CRP levels in the intensive insulin therapy group were significantly lower than those in the conventional therapy group, whereas IL-10 levels were substantially increased after intensive insulin therapy. C3 level at day 3, 5, 7 and C4 levels at day 5, 7 were lower in the intensive therapy group than in the conventional therapy group. Th1/Th2 ratios decreased gradually over time in both groups, and were much lower at day 3, 5, 7 in intensive therapy group. There were significant differences among day 3 to day 7 after admission in HLA-DR expression in CD14＋ monocytes. It was concluded that the intensive insulin therapy could decrease pro-inflammatory cytokines and increase anti-inflammatory cytokines in the elderly suffering from severe trauma, at the same time, with complement recovery being delayed. Moreover, intensive insulin therapy promoted immune suppression and, therefore, measures need be taken to address the issue.

Effect of liniment levamisole on cellular immune functions of patients with chronic hepatitis B

AIM: To explore the effects of liniment levamisole on cellular immune functions of patients with chronic hepatitis B. METHODS: The levels of T lymphocyte subsets and mlL-2R in peripheral blood mononuclear cells (PBMCs) were measured by biotin-streptavidin (BSA) technique in patients with chronic hepatitis B before and after the treatment with liniment levamisole. RESULTS: After one course of treatment with liniment levamisole, the levels of CD3+, CD4+, and the ratio of CD4+/CD8+ increased as compared to those before the treatment but the level of CD8+ decreased. The total expression level of mIL-2R in PBMCs increased before and after the treatment with liniment levamisole. CONCLUSION: Liniment levamisole may reinforce cellular immune functions of patients with chronic hepatitis B.

T lymphocyte proportion in Alzheimer’s disease prognosis

Bai et al investigate the predictive value of T lymphocyte proportion in Alzheimer's disease(AD)prognosis.Through a retrospective study involving 62 AD patients,they found that a decrease in T lymphocyte proportion correlated with a poorer prognosis,as indicated by higher modified Rankin scale scores.While the study highlights the potential of T lymphocyte proportion as a prognostic marker,it suggests the need for larger,multicenter studies to enhance generalizability and validity.Additionally,future research could use cognitive exams when evaluating prognosis and delve into immune mechanisms underlying AD progression.Despite limitations inherent in retrospective designs,Bai et al's work contributes to understanding the immune system's role in AD prognosis,paving the way for further exploration in this under-researched area.

Impairment of innate immune responses in cirrhotic patients and treatment by branched-chain amino acids

It has been reported that host defense responses, such as phagocytic function of neutrophils and natural killer (NK) cell activity of lymphocytes, are impaired in cirrhotic patients. This review will concentrate on the impairment of innate immune responses in decompensated cirrhotic patients and the effect of the treatment by branched-chain amino acids (BCAA) on innate immune responses. We already reported that phagocytic function of neutrophils was significantly improved by 3-mo BCAA supplementation. In addition, the changes of NK activity were also significant at 3 mo of supplementation compared with before supplementation. Also, Fisher&#x02019;s ratios were reported to be significantly increased at 3 mo of BCAA supplementation compared with those before oral supplementation. Therefore, administration of BCAA could reduce the risk of bacterial and viral infection in patients with decompensated cirrhosis by restoring impaired innate immune responses of the host. In addition, it was also revealed that BCAA oral supplementation could reduce the risk of development of hepatocellular carcinoma in cirrhotic patients. The mechanisms of the effects will also be discussed in this review article.

Methods： Twelve cases of stage III NSCLC in Tumor Radiotherapy Center of our hospital （the Affiliated Hospital of Medical College Qingdao University, China） were collected from July 2011 to July 2012; all patients were under 75 years old with clear pathology, measurable lesions and good personal statement. They were randomly divided into combined treatment group （D1 ＋ D2） and control group （D1）. The control group （D1） only received radiotherapy to the chest; combined treatment group （D1 ＋ D2） received low-dose splenic irradiation plus conventional dose irradiation. Flow cytometry was used to detect the peripheral blood T lymphocyte immune indexes of patients before, during and after the treatment, classification by five blood cell analyzer was used to determine white blood cells, neutrophils, hemoglobin and platelet count. The radiation induced toxicity including esophagitis, pneumonia and gastrointestinal reaction was observed, as well as the dose when it happened. Results： There was no significant difference in the ratio between two groups in cells CD4＋, CD8＋ and CD4＋/CD8＋ after radiotherapy （P 〉 0.05）. There was no change in these indicators in combined treatment group after treatment （P 〉 0.05）, but it decreased in control group （P 〈 0.05）. There was no significant difference in the incidences of radiation esophagitis, pneumonia, gastrointestinal reactions and bone marrow suppression between two groups （P 〉 0.05）, but the patients in combined treatment group seemed to tolerate high dose well （P 〈 0.05）. Conclusion： Low-dose splenic irradiation combined with radiotherapy to the chest can alleviate the injury degree of acute radiation induced the toxicity of locally advanced NSCLC patients, through affect the patient＇s immune function.
