  • Four technical grade organophosphate pesticides (Fenitrothion, Fenthion, Dizninon and EPN) were investigated for their effects on the murine immune function. Among the immunotoxicological assay parameters of NIEHS, humoral immune parameter and pathotoxicological indicators were examined in this study. Subchronic exposure of rodents to these pesticides resulted in marked suppression of humoral immune function and moderate histological changes of lymphoid organ any significant alterations of clinical status.

  • The nutritional status of host has a profound effect on immune response and its ability to defend aganinst invading pathogen. Almost all nutrient dificiencies impaired host defence, and more than recommended levels of certain nutrient enhance immune response beyond that observed with 'adequate'. But high-fat diets have been associated with various types of immune dysfunction in experimental animal models and humans. Also, high linoleic acid suppressed immune function and growth and metastasis of tumor than saturated fatty acids. The present review focused on the effect of dietary lipid on immune fuction, cytokine production and clinical conditions like infection, autoimmune disease and cancer.

  • The current study is the first paper on FPT(failure of passive transfer) of horse population in Korea. The object of this study was to comparison of immune status normal and patient horses. Failure of passive transfer is the most common immunodeficiency disorder of horses. Twenty-two foals and 18 horses from Jeju of the equine hospital were diagnosed with the SNAP Foal IgG Test Kit. All adult horses had normal immune functions (≥800 mg/dl). Thirteen of the 22 newborn babies (59%; ∠800 mg/dl) had a weak immune function but recovered and survived after treatment. Nine of these 22 are horses with strong immunity (≥800 mg/dl), indicating that high IgG concentrations in the blood can cause infectious diseases. There were a total of six dead, four of which were infectious diseases. In addition, early identification of infectious diseases in newborn foals is expected to help prepare systematic health management measures for the development of the disease.

  • Purpose: The study aimed at monitoring the immune status of health care workers (HCWs) of a tertiary hospital after accidental exposure to Hepatitis B virus (HBV). Methods: Between January 2004 and December 2006, 353 cases of exposure to Hepatitis B virus were reported. The HBV-exposed HCWs were required to undergo follow-up serum tests to analyze their immune status one year after the exposure. The obtained data were then analyzed to determine the incidence of exposure and of sero-conversion. Results: In this hospital, an average of 9.8 cases of Hepatitis B exposure among HCWs was reported in a month. Follow-up tests conducted after exposure revealed that 90.4% of the HBV-exposed HCWs were positive for Hepatitis B antibody and 66.9% of the HBV-exposed HCWs were reported to have antibody levels exceeding 10 mIU/mL. Results of serum tests for the HBV antigen conducted one year after exposure were negative for all the exposed HCWs. Conclusion: Among the 79.6% of the HCWs who underwent serum tests one year after exposure the HBV sero-conversion rate was 0.0%. However, a further investigation in the form of long-term and multi-center studies is required to confirm this result. Furthermore, an active system should be established to ensure that all exposed HCWs undergo follow-up serum tests.

  • Inflammation can be a causative factor for carcinogenesis or can result from a consequence of cancer progression. Moreover, cancer therapeutic interventions can also induce an inflammatory response. Various inflammatory parameters are used to assess the inflammatory status during cancer treatment. It is important to select the most optimal biomarker among these parameters. Additionally, suitable biomarkers must be examined if there are no known parameters. We briefly reviewed the published literature for the use of inflammatory parameters in the treatment of patients with cancer. Most studies on inflammation evaluated the correlation between host characteristics, effect of interventions, and clinical outcomes. Additionally, the levels of C-reactive protein, albumin, lymphocytes, and platelets were the most commonly used laboratory parameters, either independently or in combination with other laboratory parameters and clinical characteristics. Furthermore, the immune parameters are classically examined using flow cytometry, immunohistochemical staining, and enzyme-linked immunosorbent assay techniques. However, gene expression profiling can aid in assessing the overall peri-interventional immune status. The checklists of guidelines, such as STAndards for Reporting of Diagnostic accuracy and REporting recommendations for tumor MARKer prognostic studies should be considered when designing studies to investigate the inflammatory parameters. Finally, the data should be interpreted after adjusting for clinically important variables, such as age and cancer stage.

  • This study was performed to evaluate the effect of iron supplement for 4 weeks on iron status, immunity, and antioxidant status of national female soccer players (n = 25). This study was performed at summer hard training period right before competition. A single blind design was used to divide the subjects into iron-supplement (IS) or placebo group (P). Iron-supplement group was supplemented with iron (40 mg/d) for 4 weeks. The mean age of the subjects was 23.3 $\pm$ 2.5 years old. Mean height and body weight of the subjects were 164.4 $\pm$ 5.7 em and 57.4 $\pm$ 4.6 kg, respectively. The mean carrier as soccer player was 11.0 $\pm$ 2.6 years and mean training time was 7.0 $\pm$ 1.3 hr/day. The mean hemoglobin, hematocrit, total iron binding capacity and ferritin concentrations before iron supplementation were not different between two groups. After 4 weeks of summer training and iron supplementation, serum ferritin level was significantly increased only in IS group after supplementation. Mean corpuscular volume and total iron binding capacity were significantly decreased in both groups. Meanwhile, hemoglobin and red blood cell count were significantly lowered only in placebo group. The IgM concentration increased significantly in both groups, but IgG concentration had increasing tendency only in IS group (p < 0.064). Therefore, iron supplementation during hard training period may be helpful to improve work capacity of the athletes by improving ferritin status and humoral immune responses.

  • BACKGROUND/OBJECTIVES: We investigated the effect of Pycnogenol (Pyc) on survival and immune dysfunction of C57BL/6 mice induced by low micronutrient supplementation. MATERIALS/METHODS: Female C57/BL/6 mice were fed a diet containing 7.5% of the recommended amount of micronutrients for a period of 12 wks (immunological assay) and 18 wks (survival test). For immunological assay, lymphocyte proliferation, cytokine regulation, and hepatic oxidative status were determined. RESLUTS: Pyc supplementation with 50 and $100mg{\cdot}kg^{-1}{\cdot}bw{\cdot}d^{-1}$ resulted in partial extension of the median survival time. Pyc supplementation led to increased T and B cell response against mitogens and recovery of an abnormal shift of cytokine pattern designated by the decreased secretion of Th1 cytokine and increased secretion of Th2 cytokine. Hepatic vitamin E level was significantly decreased by micronutrient deficiency, in accordance with increased hepatic lipid peroxidation level. However, Pyc supplementation resulted in a dose-dependent reduction of hepatic lipid peroxidation, which may result from restoration of hepatic vitamin E level. CONCLUSION: Findings of this study suggest that Pyc supplementation ameliorates premature death by restoring immune dysfunction, such as increasing lymphocyte proliferation and regulation of cytokine release from helper T cells, which may result from the antioxidative ability of Pyc.

  • An experiment was conducted using 20 male buffalo calves to study the effect of vitamin E and selenium supplementation on their immune response and plasma ${\alpha}$-tocopherol and selenium status. These buffalo calves (10-12 months old, average body weight $75.30{\pm}2.20 $ kg) were randomly allotted to four treatments on the basis of their body weights and were fed on wheat straw and concentrate mixture to meet their nutrient requirements of 500 g/d body weight gain. The buffalo calves were fed either a control diet (neither supplemented with Se nor VE) or diets supplemented with Se at 0.3 ppm (+Se), DL-alpha tocopheryl acetate at 300 IU (+VE), and both DL-alpha tocopheryl acetate at 300 IU and Se at 0.3 ppm (+Se+VE). These experimental diets were fed for 180 days. Blood samples were collected at day 0 and subsequently at 45 day intervals up to 180 days of experimental feeding to monitor plasma ${\alpha}$-tocopherol and Se concentrations. To assess humoral immune response, all calves were sensitized with formalin inactivated Pasteurella multocida antigen at 135 days of experimental feeding and blood was collected on 0, 7, 14, 21 and 28 days post vaccination (DPV) to measure antibody production using indirect ELISA. Cell mediated immune response of calves was assessed after 180 days of experimental feeding by in vivo delayed type hypersensitivity (DTH) reaction using phytohaemaglutinin-P (PHA-P) as a mitogen. Results revealed that feeding of VE and Se improved the plasma levels of these nutrients. Plasma levels of Se were affected by supplementation of both VE (p<0.001) and Se (p<0.001); however, no interaction ($Se{\times}VE$) was observed. Supplementation of Se improved the humoral immune response (p<0.008), whereas, VE showed a tendency towards improvement in cell mediated immune response (p<0.064). It was concluded that vitamin E and Se supplementation improved the status of these micronutrients and humoral immune response in buffalo calves.

  • This study was to identify the levels of perceived stress, immunity cells, physical health and depression, and their relationships among those variables in the elderly who institutionalized comparing home residents. The result of this study can be used as basic data when applying nursing interventions to increase quality of life in the elderly. The questionnaires to estimate stress, health status and depression were collected through direct interview from July to August in 1999 and immunity cells were measured by venous blood specimen collected from 9 to 10 A.M. during the same period. The collected data were analysed using SAS program. The results were as follows. The score of perceived stress of all subjects was 38.49 and perceived stress score of institutionalized elderly(42.62) was significantly higher than that in home resident elderly(34.52). All immune cells tested in this study such as total T cell, helper T cell, suppressor T cell, T4/T8 ration, total B cell, and NK cell, were all under the standard criteria of cells distributions. Most elderly who institutionalized and reside home replied that their health status was not good. However their physical health activity was mostly good even though institutionalized elderly had more disability than home residents. The highest rate was 67.3% as disability due to arthritis. The score of depression in all subjects was 8.2 that indicated having depressive symptom. There was no difference in the depression level between institutionalized elderly and home resided elderly. There was a significant correlationship between physical health and depression, however, the rest of varibles did not show any significant relationships. In summary, the immune cells in the elderly who replied perceiving low level stress, was under normal range. Their health status was perceived as 'not good' but physical health activity was perceived as 'good'. The relationships of stress, immunity, physical health and depression were partially significant but not had evidence as enough as theoretically the suggested relationship. We suggest that further studies using large sample size and more diverse variables should be performed.

  • The purpose of this study was to compare the nutritional status and the immunocompetence of elderly women residing in urban and rural areas. Dietary food records and anthropometric measurements were used to evaluate the nutritional status of subjects. The immune function of subjects was assessed by total and differential white blood cell(WBC) counts. Total B and T Lymphocytes, and T cell subsets were quantified by flow-cytometer. Immunoglobulin G, A, and M concentrations were also measured as an index of humoral immunity. Elderly women in rural area showed a relatively lower dietary intake of total energy, protein, and iron than did urban elderly women. Total WBC, neutrophil counts, eosinophil counts, and the percentage of neutrophils among total leukocytes were significantly higher in urban elderly women than in rural women. Although the numbers of lymphocytes were not significantly different, the percentage of Lymphocytes among total leukocytes as greater in rural elderly women than in urban. Both groups did not show any significant differences in numbers of T cell subsets and NK cells. Immunoglobulin G, A, and M levels were not significantly different between the two groups, but the numbers of subjects placed under the deficient range of immunoglobulins were greater in rural than in urban elderly women. from the present study, it could be suggested that poor nutritional intake may selectively affect the number of immune cells, thereby influencing the immunocompetence of elderly women.
