  • 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.

  • A 12-year-old male American Cocker Spaniel was diagnosed with a type of chronic hepatits (CH) called cholangioheaptits. Routine supportive medication was administered to the patient, and ex vivo boosted immune cell (EBI-C) therapy was used for the treatment. A histopathologic examination of the liver 19 months later revealed that the cholangiohepatitis had progressed to cholangiocarcinoma. The medication and immune cell therapy was maintained. Two months after the new diagnosis, the patient's state worsened, and the dog died 635 days after the first visit. EBI-C therapy is a type of immunotherapy, where immune cells are isolated from the patient's peripheral blood mononuclear cells, expanded ex vivo, and then infused into the patient intravenously every two weeks. EBI-Cs (mean: 2.78 × 108 cells) were obtained 38 times and infused every two weeks. Most EBI-C were T-lymphocytes (99.24% of total EBI cells). T-lymphocytes produce large interferon (IFN)-γ, and IFN-γ inhibits liver fibrosis in dogs with CH. Moreover, in bile duct cancer, an increase in T-lymphocytes correlates with decreasing tumor invasion and metastasis. Thus, we propose that EBI-C therapy is applicable as a new supportive therapy for canine liver disease if other treatments like drug medication, surgery, or radiation are unavailable.

  • Background: Patients with colorectal cancer are usually treated with chemotherapy, which reduces the number of blood cells, especially white blood cells, and consequently increases the risk of infections. Some research studies have reported that aromatherapy massage affects the immune system and improves immune function by, for example, increasing the numbers of natural killer cells and peripheral blood lymphocytes. However, there has been no report of any study which provided good evidence as to whether aromatherapy with Thai massage could improve the immune system in patients with colorectal cancer. The objectives of this study were to determine whether the use of aromatherapy with light Thai massage in patients with colorectal cancer, who have received chemotherapy, can result in improvement of the cellular immunity and reduce the severity of the common symptoms of side effects. Materials and Methods: Sixty-six patients with colorectal cancer in Phichit Hospital, Thailand, were enrolled in a single-blind, randomised-controlled trial. The intervention consisted of three massage sessions with ginger and coconut oil over a 1-week period. The control group received standard supportive care only. Assessments were conducted at pre-assessment and at the end of one week of massage or standard care. Changes from pre-assessment to the end of treatment were measured in terms of white blood cells, neutrophils, lymphocytes, CD4 and CD8 cells and the CD4/CD8 ratio and also the severity of self-rated symptom scores. Results: The main finding was that after adjusting for pre-assessment values the mean lymphocyte count at the post-assessment was significantly higher (P=0.04) in the treatment group than in the controls. The size of this difference suggested that aromatherapy with Thai massage could boost lymphocyte numbers by 11%. The secondary outcomes were that at the post assessment the symptom severity scores for fatigue, presenting symptom, pain and stress were significantly lower in the massage group than in the standard care controls. Conclusions: Aromatherapy with light Thai massage can be beneficial for the immune systems of cancer patients who are undergoing chemotherapy by increasing the number of lymphocytes and can help to reduce the severity of common symptoms.

  • A macromolecular fraction from fresh ginseng root containing mainly polysaccharide showed mild mitogenic activity in human cord blood lymphocytes. 2) When lymphocytes were transformed by Con A or PHA, this fraction could greatly enhance the activity of these lectin mitogens, thus showing a potentiation effect. 3) Although this macromolerular fraction contains saponin and is susceptible to trypsin digestion, it is probably a peptido-glycan in nature on account of its important carbohydrate content and thermal stability. 4) This fraction could not support cancer cell (EAT, K562) growth : its inhibitory effect on these cells remains to be explored.

  • Endocrine disruptors have been implicated in carcinogenesis in animal studies, but carcinogenetic effects on human remain controversial. In order to examine the genotoxicity of two common endocrine disruptors, Bisphenol A and Diethylstilbestrol, cytogenetic endpoints including chromosome aberration (CA), sister chromatid exchange (SCE), micronuclei (MN) analyses and DNA damage by single cell gel electrophoresis (SCGE) were assessed. The effects of Bisphenol A and Diethylstilbestrol on the frequencies of CA and MN were increased in a dose-dependent manner and that of Bispheol A was more significant by Kendall'$\tau$test. Bisphenol A and Diethylstilbestrol also increased the frequency of SCE. Bisphenol A and Diethylstilbestrol induced DNA damage in a dose-dependent manner and the DNA damage induced by Diethylstilbestrol in human blood lymphocytes was more significant.

  • A population monitoring studies for assessing the genotoxicity of occupationally exposed mixed organic solvents to printers were performed by using the chromosome aberration assay and the cytokinesis-blocked micronucleus assay. The incidence of chromosome aberrations and micronuclei was studied in the peripheral blood lymphocytes of 51 male printers and their matched controls in Seoul area. Smoking habits and duration of employment were taken into account. The frequencies of micronucleus in peripheral lymphocytes of printers were significantly different in comparision with control subjects. Also there were significant increase in the frequencies of micronucleus by duration of exposure. The frequencies of chromosome aberrations showed no significant differences between printers and their matched controls.

  • Guinea pigs were administrated with T-2 toxin at a rate of 1 and 0.6mg/kg body weight per day for 21 days to study the immunological and pathological effects of T-2 toxin in guinea pigs. Blood was collected before T-2 treatment and on days 7, 14 and 21 of the trial for hematological and biological examinations and for the mitogen assay using lymphocytes. Myeloid: erythroid ratios were examined from the fernur bone marrow samples taken a day before T-2 toxin treatment began, on day 12 and at death. Guinea pigs received with 1mg/kg body weight of T-2 toxin daily showed leukopenic, lymphopenic and anemic signs on day 7 and 14. The mitogenic responses to the T-cell mitogen, Concanavalin A and B-cell mitogens, lipopolysaccharide were significantly depressed on day 7. Histologically, marked cellular damages including karyorrhexis and depletion of lymphocytes were observed in the actively dividing cells of the gastrointestinal tract, lymph node, spleen and bone marrow of guinea pigs.

  • The present study has been carried out to investigate the optimal condition on lymphocyte blastogenesis of rabbit lymphocytes, whole blood culture and microculture system in conjunction with a semiautomatic multiple sample harvester(SAMSH) was used to study the In vitro optimal condition of rabbit lymphocytes. Data were presented to show many variables that are involved in studying the phytohemagglutinin(PHA) and lipopolysaccharide(LPS) response of rabbit lymphocyte in a microculture system. Analysis indicated that the conditions for optimal PHA as measured by incorporation of $^3H$-TdR include: (1) use of RPMI-1640 as culture medium. (2) use of $6{\mu}g$ of PHA, per culture. (3) 48-hours culture period. Conditions for optimal stimulation with LPS mitogen were similar to those used for PHA.

  • Twenty species of higher fungi growing in the wild were collected and studied extensively for their lectin activities by using erythrocytes of human, rabbit and mouse blood. In total, 14 species demonstrated hemagglutination with some kinds of erythrocytes. Of twenty species, eight (Boletus edulis, B. splendidus, Clavaria zollingeri, Lactaritis subzonarius, L. volemus, Russula cutefracta, Pholiota squarrosa, and P. aspera) were shown lymphoagglutination with murine splenic lymphocytes. Protein contents were estimated from the crude lectin fraction. Above mentioned eight species contained relatively high amounts of proteins than other mushrooms. Since these species had coincidently, hiig emagglutinating activity as well, we could define them as lectin-containeing mushrooms. Some species also contained mitogenic lectins toward murine splenic lymphocytes.

  • The immunomodulating activity of a polysaccharide isolated from Morus alba (PMA) root bark was examined in murine splenic lymphocytes. PMA enhanced proliferation of splenic lymphocytes in a synergistic manner in the presence of mitogens. However, PMA suppressed pri-may IgM antibody production from B cells, which was activated with lipopolysaccharide, a polyclonal activator, or immunized with a T-cell dependent antigen sheep red blood cells. Our observations showed that the immunomodulating activity of PMA increased lymphocyte proliferation and that PMA decreased antibody production from B cells, which was distinct from those of other plant-originated polysaccharides.
