It was investigated that how the periodic exposure to heat environment, and the treatment of korean white and red ginseng extracts had effects on the weight, diet uptake, blood components, organ weight, and the lipid peroxidation of liver in male S.D. rats. In the result of experiments using rats, chronic heat environment for 7 days at $38^{\circ}C$, 5 hrs per day, induced significant decrease of an average increase rate of body weight, but diet uptake was not affected clearly. In heat environment, the number of red blood cells and hemoglobin were not changed, but the number of white blood cells was significantly increased. The liver weight against body weight was decreased in rats. Also, MDA contents, related to lipid peroxidation, were remarkably increased in rat liver by heat environment. These physiological changes were attenuated by treatments of white and red ginseng extracts before and after exposure to heat environment, particularly in growth rate and lipid peroxidation of liver in rats. Also, red ginseng extracts had a better effect, though it was not that significant, than the white ginseng on the inhibition of lipid peroxidation and the weight change of liver. Although the investigation on the effective components and the study on the activity changes of associated materials are needed to perform, these present results imply that Korean ginseng may contribute to protection of body homeostasis against drastic climate changes.

Background: Viruses can cause either meningitis or encephalitis. It is unclear why some people suffer from aseptic meningitis, and others acquire aseptic encephalitis when infected with the same viral pathogens. The aim of this study was to compare demographic and laboratory factors between patients with aseptic meningitis and encephalitis. Methods: The demographic and laboratory differences were analyzed according to age, sex, diabetes, hypertension, C-reactive protein in the blood, white blood cell and protein in the cerebrospinal fluid, and glucose ratio (cerebrospinal fluid/blood). Additionally, we analyzed the nation-wide differencesin age between the patients with aseptic meningitis and those with encephalitis in Korea. Results: The patients with aseptic encephalitis were older, more likely to have hypertension, and had higher levels of C-reactive protein than did the patients with aseptic meningitis. However, the numbers of white blood cells in the cerebrospinal fluid were significantly higher in the patients with meningitis than in the patients with encephalitis. Multivariable analysis revealed that age >49 years, hypertension and a C-reactive protein level >5.81 mg/dL were independent and significant variables in the prediction of aseptic encephalitis. Additionally, the patients with aseptic encephalitis were older than those with aseptic meningitis in the nation-wide Korean database. Conclusions: Older age, hypertension, and higher levels of C-reactive protein are useful factors for the prediction of aseptic encephalitis.

We previously demonstrated that water-soluble egg yolk extract is not related to elevation of serum immunoglobulin E, which can initiate allergic reactions; however, it increases the level of high density lipoprotein (HDL)-cholesterol and the activity of B lymphocytes. In this study, egg white (EW) was fed to BALB/c mice to determine its influence on growth efficiency, immune modulation, and changes in serum lipid levels. A total of 50 five-wk-old BALB/c male mice were divided into 5 groups, 4 of which were fed 0, 10, 50, or 100 mg/d EW for 4 wk. Mice with an uptake of 10, 50 and 100 mg/d EW showed no significant changes in daily weight gain, feed efficiency rate, or populations of white blood cells. However, the activities of both B and T lymphocytes were significantly increased in all three EW groups at the final week of treatment. Interestingly, serum levels immunoglobulin E were not altered by EW consumption, but the IgG level was significantly increased in the 100 mg/d EW group. Serum lipid profile analyses showed no significant changes in total cholesterol, HDL, low density lipoprotein, or triglyceride levels by EW consumption. Taken together, these data demonstrate that consumption of EW promotes immune cell activities and the upregulation of serum IgG levels. However, we found no changes in serum lipid profiles and IgE levels. Therefore, our study suggests that consumption of EW might not be related to the risk of food allergy, but could be an excellent candidate for the maintenance of physiological homeostasis.

Five hundred and forty crossbred (Korean native black pig${\times}$Landrace) F2 were selected at a commercial pig farm and then divided into six different coat color groups: (A: Black, B: White, C: Red, D: White spot in black, E: Black spot in white, F: Black spot in red). Birth weight, 21st d weight, 140th d weight and carcass weight varied among the different coat color groups. D group (white spot in black coat) showed a significantly higher body weight at each weigh (birth weight, 140th d weight and carcass weight) than did the other groups, whereas the C group (red coat color) showed a significantly lower body weight at finishing stage (140th d weight and carcass weight) compared to other groups. Meat quality characteristics, shear force, cooking loss and meat color were not significantly different among the different coat color groups, whereas drip loss was significantly higher in F than in other groups. Most blood characteristics were not significantly different among the different groups, except for the red blood cells.

In this study, we investigated the immune-enhancing activity of water extracts from Hydrangea macrophylla subsp. serrata (WE-HML). WE-HML increased cell viability and production of immunomodulators, which contributed to activating phagocytic activity in RAW264.7 cells. Inhibition of JNK and NF-κB reduced the production of immunomodulators by WE-HML. ROS inhibition suppressed the production of immunomodulators, and the activation of JNK and NF-κB signaling by WE-HML. TLR4 inhibition attenuated the production of immunomodulators, and activation of JNK and NF-κB signaling by WE-HML. In the immunosuppressed mouse model, WE-HML increased the spleen index, the levels of the cytokines, the numbers of white blood cells, lymphocytes, and neutrophils. However, WE-HML inhibited LPS-mediated overproduction of pro-inflammatory mediators in RAW264.7 cells, which indicated that WE-HML may have anti-inflammatory activity under excessive inflammatory conditions. Taken together, WE-HML may be considered to have immune-enhancing activity and expected to be used as a potential immune-enhancing agent.

Leukemia is a neoplastic disease with an excessive proliferation of immature white blood cells and their precursors. Common oral manifestations of acute myeloid leukemia (AML) include ulceration, petechiae, spontaneous bleeding, and gingival hyperplasia. The estimated prevalence of AML is 19 per 100,000 populations, the median age of diagnosis is over 65 years, and of all the subtypes of leukemia, AML accounts for the highest percentage of leukemic deaths. The purpose of this study is to report the case of a 77-year-old female patient, who visited our outpatient clinic due to consistent inflammatory findings. Though she received surgical treatment, she was diagnosed with AML by chance after a preoperative blood test. We also discuss the necessity of performing a preoperative blood test prior to invasive dental procedures such as tooth extraction or biopsy.

During an 8 month period from January to August 2007, complete blood count (CBC) samples were taken from various wards and from the outpatient department at Samsung Medical Center. In order to determine whether or not the total white blood cells were over counted, results were obtained from both the 4Diff/channel and the white blood cell channel from the automated blood analysis equipment from S company for comparison. Among patients who were on long term treatments, the number of cases determined to be over counted by comparing the WBC counts during this 8 month period was 25. Clinical chemistry tests were also conducted on the same day on the 25 samples taken. 68% of the patients showed to exceed normal range of aspartate transaminase (AST) and alanine aminotransferase (ALT) indicating abnormal liver function, and the total bilirubin range were also in excess in 60% of the total samples taken. Further clinical information which was obtained from the patients showed 98% of the patients were administered with cefepime which is the 4th generation cephalosporin at the time when the WEC were over counted. It is assumed that a multiple of factors investigated caused the over count of the WEC rather than a single factor.

Seeds or beans of 55 plants belonging to 31 families were screened by using several different types of red blood cells to find new lectins. In this paper, white kidney been (phaseolus vulgaris C.) was chosen to study biochemical properties of hemagglutinating proteins(lectins). An anion exchanger, DEAE Sephadex A-50, and polyacrylamide disc gel electrophoresis were main techniques used. From three main fractions eluted by stepwise NaCl gradient in 25mM Tris-HCI buffer on DEAE Sephadex column, principal lectin was identified.

This study was undertaken to elucidate the mechanism of the cyclophosphamide(CY)-induced potentiation of cell-mediated immune response by observing the effect of the phytohemaggllutinin(PHA) treatment before the CY administration into mice. Cy administration reduced the circulating white blood cells especially lymphocyte. PHA pretreatment before CY administration enhanced the depressing effect of CY administration on white blood cells. CY administration suppressed both the antibody formation to sheep red blood cells(SRBC) and rosette formation on the spleen cells with SRBC severely. On the other hand, CY administration potentiated the delayed-type hypersensitivity(DTH) strongly. Injection of PHA into mice slightly inhibited both the antibody formation and the DTH. PHA pretreatment before CY administration into mice suppressed not only humoral immune response but also cell-mediated immune response and the degrees of suppression were most remarkable when the PHA pretreatment was performed 5 days before CY administration. This depression of DTH caused by PHA pretreatment before CY administration may be the result that PHA stimulation make the helper cell sensitive to CY. The potentiation of cell-mediated immune response by CT may be due to the destruction of CY-sensitive suppressor T cell.
