Background : The poor prognostic factors of far-advanced pulmonary tuberculosis(FAPTB) are lymphocytopenia in the peripheral blood(PB)(< $1,000/mm^3$) and $T_4$-cell count ${\leq}500/mm^3$. However, the cause of PB lymphocytopenia in FAPTB is unclear. The aim of this study was to analyze the lymphocyte proportion and cytokines of the bone marrow(BM) in FAPTB patients with peripheral lymphocytopenia in order to clarify whether the limiting step of the lymphocytopenia occurs in production, differentiation, or circulation. Methods : This study included patients with FAPTB between August 1999 and August 2002 who visited Gachon Medical School Gil Medical Center. The exclusion criteria were old age(${\geq}65years$), cachexia or a low body weight, shock, hematologic diseases, or BM involvement of tuberculosis. The distributions of cells in PB and BM were analyzed and compared to the control group. The interleukin(IL)-2, IL-7, IL-10, TNF-${\alpha}$, Interferon-${\gamma}$, and TGF-${\beta}$ levels in the BM were measured by ELISA. Result : Thirteen patients(male : female=9:4) were included and the mean age was $42{\pm}12$years. The proportion and count of the lymphocytes in the PB were significantly lower in the FAPTB group ($7.4{\pm}3.0%$, $694{\pm}255/mm^3$ vs. $17.5{\pm}5.8%$, $1,377{\pm}436/mm^3$, each p=0.0001 and 0.002). The proportion of immature lymphocyte in the BM showed a decreasing trend in the FAPTB group($9{\pm}4%$ vs. $12{\pm}3%$, p=0.138). The IL-2($26.0{\pm}29.1$ vs. $112.2{\pm}42.4pg/mL$, p=0.001) and IL-10($3.4{\pm}4.7$ vs. $12.0{\pm}8.0pg/mL$, p=0.031) levels in the BM were significantly lower in the FAPTB group than those in control. The levels of the other cytokines in FAPTB group and control were similar. Conclusion : These results suggest that the cause of lymphocytopenia in PB is associated with a abnormality IL-2 and IL-10 production in the BM. More study will be needed to define the mechanism of a decreased reservoir in BM.

Objective : This study was carried out to investigate the effects of the hormones and cytokines associated with bone metabolism in ovariectomized rats. Method : Twenty-four Female-Sprague-Dawley rats were divided into sham operated(normal) group, ovariectomized(control)group, ovariectomized and treated with extract Caraganae Sinicae Radix(treated) group. Each group was investigated the changes of body weight at 3,5,7weeks after treatment, and femur weight, femur/body weight, thickness of compact bone of body of femur, area of cancellous bone of distal epiphysis of femur, serum estrogen, serum calcitonin, serum parathormone, serum Tumor Necrosis $Factor-{\alpha}$, serum $lnterleukin-1{\beta}$ at 7weeks after treatment. The results were summerized as follows; 1. The treated group showed significant change in body weight compared with the control group at 5,7weeks after treatment. 2. The treated group revealed significant increases in femur/body weight compared with the control group. 3. The treated group showed a little thicker compact bone of body of femur than the control group. 4. The area of cancellous bone of distal epiphysis of femur in treated group was increased significantly compared with control group. 5. The level of serum estrogen showed no change compared with control group. 6. The level of serum calcitonin showed no change compared with control group. 7. The level of serum parathormone was decreased in treated group significantly compared with control group. 8. The level of serum $TNF-{\alpha}$ was decreased in treated group significantly compared with control group. 9. The level of serum $interleukin-1{\beta}$ showed no change compared with control group. The results indicate that Caraganae Sinicae Radix inhibits bones resorption in ovariectomized rats by it's lowering effects on serum parathormone and $TNF-{\alpha}$.
Calcium ions play an important role in the establishment and maintenance of pregnancy, but molecular and cellular regulatory mechanisms of calcium ion action in the uterine endometrium are not fully understood in pigs. Previously, we have shown that calcium regulatory molecules, transient receptor potential vanilloid type 5 (TRPV6) and calbindin-D9k (S100G), are expressed in the uterine endometrium during the estrous cycle and pregnancy in a pregnancy status- and stage-specific manner, and that estrogen of conceptus origin increases endometrial TRPV6 expression. However, regulation of S100G expression in the uterine endometrium and conceptus expression of S100G has been not determined during early pregnancy. Thus, we investigated regulation of S100G expression by estrogen and interleukin-$1{\beta}$ (IL1B) in the uterine endometrium and conceptus expression of S100G during early pregnancy in pigs. We obtained uterine endometrial tissues from day (D) 12 of the estrous cycle and treated with combinations of steroid hormones, estradiol-$17{\beta}$ ($E_2$) and progesterone ($P_4$), and increasing doses of IL1B. Real-time RT-PCR analysis showed that $E_2$ and IL1B increased S100G mRNA levels in the uterine endometrium, and conceptuses expressed S100G mRNA during early pregnancy, as determined by RT-PCR analysis. To determine if endometrial expression of S100G mRNA during the implantation period was affected by the somatic cell nuclear transfer (SCNT) procedure, we compared S100G mRNA levels in the uterine endometrium from gilts with SCNT-derived conceptuses with those from gilts with conceptuses derived from natural mating on D12 of pregnancy. Real-time RT-PCR analysis showed that levels of S100G mRNA in the uterine endometrium from gilts carrying SCNT-derived conceptuses was significantly lower than those from gilts carrying conceptuses derived from natural mating. These results showed that S100G expression in the uterine endometrium was regulated by estrogen and IL1B of conceptus origin, and affected by the SCNT procedure during early pregnancy. These suggest that conceptus signals regulate S100G, an intracellular calcium transport protein, for the establishment of pregnancy in pigs.
Objective: An experiment was conducted to evaluate the effects of Lonicera japonica extract (LJE) on milk production, rumen fermentation and blood biomarkers of energy metabolism, inflammation and oxidative stress during the perinatal period of Holstein dairy cows. Methods: Eighteen Holstein dairy cows were used in a complete randomized design experiment with 3 dietary treatments and 6 cows per treatment. All cows received the same basal total mixed ration (TMR) including a prepartal diet (1.35 Mcal of net energy for lactation [NEL]/kg of dry matter [DM], 13.23% crude protein [CP]) from -60 d to calving and a postpartal diet (1.61 Mcal of NEL/kg of DM, 17.39% CP) from calving to 30 days in milk (DIM). The 3 dietary treatments were TMR supplemented with LJE at 0 (control), 1 and 2 g/kg DM, respectively. LJE was offered from 21 d before calving to 30 DIM. Dry matter intake (DMI) and milk production were measured daily after calving. Milk and rumen fluid samples were collected on 29 and 30 d after calving. On -10, 4, 14, and 30 d relative to calving, blood samples were collected to analyze the biomarkers of energy metabolism, inflammation and oxidative stress. Results: Compared with control diet, LJE supplementation at 1 and 2 g/kg DM increased DMI, milk yield and reduced milk somatic cell count. LJE supplementation also decreased the concentrations of blood biomarkers of pro-inflammation (interleukin-1β [IL-1β], IL-6, and haptoglobin), energy metabolism (nonesterified fatty acid and β-hydroxybutyric acid) and oxidative stress (reactive oxygen metabolites), meanwhile increased the total antioxidant capacity and superoxide dismutase concentrations in blood. No differences were observed in rumen pH, volatile fatty acid, and ammonia-N (NH3-N) concentrations between LJE supplemented diets and the control diet. Conclusion: Supplementation with 1 and 2 g LJE/kg DM could increase DMI, improve lactation performance, and enhance anti-inflammatory and antioxidant capacities of dairy cows during perinatal period.

Objectives: This study was performed to identify the anti-inflammatory effects of Salvia miltiorrhizae radix Water extract (SMW) on lipopolysaccharide (LPS) induced inflammation. Methods: RAW 264.7 cells were treated with 500 ng/ml of LPS. SMW (0.1, 0.25, 0.5 mg/ml) was treated 1 h prior to LPS. Cell viability was measured by MTT assay. Levels of nitric oxide (NO) were measured with Griess reagent and pro-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (PCR). We also examined molecular mechanisms such as mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B ($NF-{\kappa}B$) activation by western blot. In addition, we observed mice survival rate after LPS and examined their cytokine levels of serum and liver tissue. Results: SMW itself did not have cytotoxic effects in RAW 264.7 cells less than 0.5 mg/ml. SMW treatment inhibited the production of NO, and interleukin $(IL)-1{\beta}$ which is pro-inflammatory cytokine. And SMW treatment inhibited the LPS-induced activation of MAPKs such as extracellular signal-regulated kinase1/2 (ERK1/2), p38 kinases (p38), c-Jun NH2-terminal kinase (JNK) and $NF-{\kappa}B$. In addition, it also showed reducing the level of $IL-1{\beta}$ on the serum and liver tissue of mice. Also, death of LPS-induced mice was inhibited by SMW. Conclusions: The result suggests that treatment of SMW could reduce the LPS-induced inflammation. Thereby, SMW could be used as a protective agent against inflammation. Also, this study could give a clinical basis that SMW could be a drug or agent to prevent inflammatory diseases.
Background: Air pollution has led to an increased exposure of all living organisms to fine dust. Therefore, research efforts are being made to devise preventive and therapeutic remedies against fine dust-induced chronic diseases. Methods: Research of the respiratory protective effects of KRG extract in a particulate matter (PM; aerodynamic diameter of <4 ㎛) plus diesel exhaust particle (DEP) (PM4+D)-induced airway inflammation model. Nitric oxide production, expression of pro-inflammatory mediators and cytokines, and IRAK-1, TAK-1, and MAPK pathways were examined in PM4-stimulated MH-S cells. BALB/c mice exposed to PM4+D mixture by intranasal tracheal injection three times a day for 12 days at 3 day intervals and KRGE were administered orally for 12 days. Histological of lung and trachea, and immune cell subtype analyses were performed. Expression of pro-inflammatory mediators and cytokines in bronchoalveolar lavage fluid (BALF) and lung were measured. Immunohistofluorescence staining for IRAK-1 localization in lung were also evaluated. Results: KRGE inhibited the production of nitric oxide, the expression of pro-inflammatory mediators and cytokines, and expression and phosphorylation of all downstream factors of NF-κB, including IRAK-1 and MAPK/AP1 pathway in PM4-stimulated MH-S cells. KRGE suppressed inflammatory cell infiltration and number of immune cells, histopathologic damage, and inflammatory symptoms in the BALF and lungs induced by PM4+D; these included increased alveolar wall thickness, accumulation of collagen fibers, and TNF-α, MIP2, CXCL-1, IL-1α, and IL-17 cytokine release. Moreover, PM4 participates induce alveolar macrophage death and interleukin-1α release by associating with IRAK-1 localization was also potently inhibited by KRGE in the lungs of PM4+D-induced airway inflammation model. KRGE suppresses airway inflammatory responses, including granulocyte infiltration into the airway, by regulating the expression of chemokines and inflammatory cytokines via inhibition of IRAK-1 and MAPK pathway. Conclusion: Our results indicate the potential of KRGE to serve as an effective therapeutic agent against airway inflammation and respiratory diseases.
Purpose : Fungal infection is one of the important causes of morbidity and mortality in patients with hematologic malignancies. Amphotericin B(ABV) and itraconazole(ITZA) have been used as the standard empirical antifungal therapy in neutropenic patients with acute leukemia who have persistent fever that does not respond to antibiotic therapy. ABV is an antifungal drug associated with side effects such as fever and chills, symptoms which may be mediated by pro-inflammatory cytokines such as interleukin-$1{\beta}$(IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$). We assessed modulation of these pro-inflammatory cytokines as well as the anti-inflammatory cytokines(IL-4, IL-1Ra) by ABV and ITZA. Methods : From March 2004 to February 2005, a total of 30 episodes from acute leukemia patients with febrile neutropenia were analyzed for this study. They were randomly allocated to receive intravenous ABV or ITZA for 14 days. Clinical responses were evaluated at the completion of therapy, and cytokine IL-$1{\beta}$, TNF-${\alpha}$, IL-4, and IL-1Ra were measured for determination to know the correlation between two antifungal agents and inflammatory cytokines. Results : Empirical antifungal agents were given to 37 patients(ABV 20, ITZA 17), and 30 patients(ABV 15, ITZA 15) were evaluable for efficacy. White blood cell and absolute neutrophil count in the group treated with ITZA increased early days of treatment, so the duration of neutropenia in ITZA group is shorter. Serum creatinine level is lower in ITZA group than in ABV group but this is not statistically significant. There was no significant difference in response rate between two groups. The IL-$1{\beta}$ was increased in ABV treatment group and the ratio of IL-1Ra/IL-$1{\beta}$ is markedly decreased in ABV treatment group while increased in ITZA group. Conclusion : ITZA and ABV have at least equivalent efficacy as empirical antifungal therapy in neutropenic children with acute leukemia. However ITZA is associated with significantly less toxicity in clinical and molecular aspects.
Objective: Adipose tissue is no longer considered as an inert storage organ for lipid, but instead is thought to play an active role in regulating insulin effects via secretion adipokines. However, conflicting reports have emerged regarding the effects of adipokines. In this study, we investigated the role of adipokines in glucose metabolism and insulin sensitivity in obese Bama mini-pigs. Methods: An obesity model was established in Bama mini-pigs, by feeding with high-fat and high-sucrose diet for 30 weeks. Plasma glucose and blood biochemistry levels were measured, and intravenous glucose tolerance test was performed. Adipokines, including adiponectin, interleukin-6 (IL-6), resistin and tumor necrosis factor alpha ($TNF-{\alpha}$), and glucose-induced insulin secretion were also examined by radioimmunoassay. AMP-activated protein kinase (AMPK) phosphorylation in skeletal muscle, which is a useful insulin resistance marker, was examined by immunoblotting. Additionally, associations of AMPK phosphorylation with plasma adipokines and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed by Pearce's correlation analysis. Results: Obese pigs showed hyperglycemia, high triglycerides, and insulin resistance. Adiponectin levels were significantly decreased (p<0.05) and IL-6 amounts dramatically increased (p<0.05) in obese pigs both in serum and adipose tissue, corroborating data from obese mice and humans. However, circulating resistin and $TNF-{\alpha}$ showed no difference, while the values of $TNF-{\alpha}$ in adipose tissue were significantly higher in obese pigs, also in agreement with data from obese humans but not rodent models. Moreover, strong associations of skeletal muscle AMPK phosphorylation with plasma adiponectin and HOMA-IR index were obtained. Conclusion: AMPK impairment induced by adiponectin decrease mediates insulin resistance in high-fat and high-sucrose diet induction. In addition, Bama mini-pig has the possibility of a conformable model for human metabolic diseases.
Ultra-fine powder (FA) extracts from persimmon were investigated as potential food materials in industrial processes because such extracts have various useful biological activities. We examined the antioxidant and anti-allergic activity of FA extracts using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing activity of plasma (FRAP) models, and by measuring interleukin 4 (IL-4) expression in spleen cells and in an atopy animal model. FA extracts were prepared using solvents including distilled water and 50% (v/v) acetone. The results showed that FA extracts had potent DPPH and FRAP activities, decreased IL-4 expression in spleen cells, and inhibited ear thickness and inflammation in a mouse animal model. The data indicate that a FA extract could be used as an antioxidant and/or anti-inflammation agent, and in industrial food preparation processes.

Platycodon grandiflorus (P. grandiflorus) flower is a perennial plant belonging to the family Campanulaceae and has many excellent pharmacological effects, so it has been used as a medicinal ingredient since ancient times. In addition, anthocyanin is a purple or blue natural pigment contained in plant flowers and fruits, and is known as a powerful antioxidant. The purpose of this study was to confirm the dermatological functionality of P. grandiflorus flower extract and the value of the bluish anthocyanin contained in flowers as a cosmetic material as a natural pigment. Firstly, 50% ethanol and 80% ethanol were added to the P. grandiflorus flower and extracted under reflux for 4 h at 25, 60, and 80 ℃, and the pH of each treatment group was similar. Based on the anthocyanin content and chromaticity (E*ab), 50% ethanol 60 ℃ extraction conditions showing the color development most similar to the natural color of the P. grandifloras flower were selected, and a sample was prepared by concentrating and lyophilizing. The analysis results showed that the total phenol, total flavonoid, and total anthocyanin contents were in the ranges of 23 ㎍/mL, 16 ㎍/mL, and 0.17 ㎍/mL, respectively. The P. grandiflorus flower extract suppressed the production of nitric oxide (NO) and interleukin-6 (IL-6) in lipopolysaccharide (LPS) induced RAW264.7 cells. Furthermore, the P. grandiflorus flower extract showed wound healing effects through the promotion of skin cell migration in TNF-α stimulated human keratinocytes. The stability of anthocyanin and extract color was studied during a storage period of 50 days at various temperatures (4 ℃, 25 ℃, and 45 ℃). Color values (L, a, and b) of the P. grandiflorus flower extract changed over 50 days, whereas the bluish-purple color of the extract was stabilized using 5% maltodextrin. These results suggest that P. grandiflorus flower extract may be useful as a natural cosmetic pigment.
