  • Korean pine nut oil (PNO) has been reported to have favorable effects on lipid metabolism and appetite control. We investigated whether PNO consumption could influence weight gain, and whether the PNO-induced effect would result in an improvement of immune function in high-fat diet (HFD)-induced obese mice. C57BL/6 mice were fed control diets with 10% energy fat from either PNO or soybean oil (SBO), or HFDs with 45% energy fat from 10% PNO or SBO and 35% lard, 20% PNO or SBO and 25% lard, or 30% PNO or SBO and 15% lard for 12 weeks. The proliferative responses of splenocytes upon stimulation with concanavalin A (Con A) or lipopolysaccharide (LPS), Con A-stimulated production of interleukin (IL)-2 and interferon (IFN)-${\gamma}$, and LPS-stimulated production of IL-6, IL-$1{\beta}$, and prostaglandin $E_2$ ($PGE_2$) by splenocytes were determined. Consumption of HFDs containing PNO resulted in significantly less weight gain (17% less, P < 0.001), and lower weight gain was mainly due to less white adipose tissue (18% less, P = 0.001). The reduction in weight gain did not result in the overall enhancement in splenocyte proliferation. Overall, PNO consumption resulted in a higher production of IL-$1{\beta}$ (P = 0.04). Replacement of SBO with PNO had no effect on the production of IL-2, IFN-${\gamma}$, IL-6, or $PGE_2$ in mice fed with either the control diets or HFDs. In conclusion, consumption of PNO reduced weight gain in mice fed with HFD, but this effect did not result in the overall improvement in immune responses.

  • Background: This study was designed using a mouse model of atopic dermatitis [phthalic anhydride (PA)-treated mice], to investigate the anti-inflammatory effect of bee venom pharmacopuncture (BVP) in keratinocytes. Methods: Western blot analysis was performed to investigate inflammation related protein expression of iNOS, COX-2, phospho-ERK (p-ERK), and ERK, in LPS (1 ㎍/mL)-activated keratinocytes, following BVP treatment, and in PA-treated mice, after BVP treatment. Griess reaction was performed to investigate NO concentration. Enzyme-linked immunosorbent assays were used to determine the concentrations of interleukin (IL)-4+, IL-17A+, IL-13 and IL-4 in PA-treated mice after BVP treatment. In addition, monocyte, macrophage, neutrophil, and eosinophil counts were measured to observe the changes in white blood cell infiltration. Results: The keratinocytes of the BVP-treated group showed a decreased expression of iNOS, COX-2, ERK at 5 OX-2, ERK E, and p-ERK at 1, 2 and 5 RKRK ERK ERK, and a dose-dependent decrease in NO concentration at 2 and 5 ntrationof s. In the BVP-treated groups (0.1 μ.1-trea μ.1-treated gr), PA-treated mice showed recovery after 4 weeks which was dose-dependent, showing a significant decrease in clinical scores for AD, and a decreased concentration of IL-13 and IL-4 with BV treatment. There was a dose-dependent decrease in the infiltration of eosinophils, neutrophils, monocytes, macrophages, and a decreased thickness of the epidermis due to inflammation, and decreased expressions of iNOS, COX-2, p-ERK, ERK, especially in the 0.1 μ0/mL BVP-treated group, Conclusion: These results suggest that BVP may be an effective alternative treatment for atopic dermatitis.

  • Objective : This study is conducted to evaluate the efficiency of ethanol extracts of 4 mixed herbs(CP001 or CP002) on mouse model of atopic dermatitis induced by ovalbumin. Methods : Female BALB/c mice were internally sensitized with ovalbumin($20{\mu}g$) plus aluminum hydroxide hydrate(4mg) once per week. After 3 weeks, they were dermally challenged with patches containing ovalbumin ($100{\mu}g$) plus aluminum hydroxide hydrate(20mg) every other day for 3 weeks. After induction of atopic dermatitis, mice back skin were gently rubbed with CP001 or CP002(200mg/$m{\ell}$, $100{\mu}{\ell}$) for two weeks(every 2 days). Results : In CP001 or CP002 treated group, there was a remarkable reduction in infiltration of eosinophils on the skin areas and diminution of mast cells and total T cells in blood samples as compared with control group. Cutaneous expressions of interleukin-13, 17 were also decreased by CP001 or CP002. Moreover, blood immunoglobulin E level was decreased by drug administration while there was no decrease in OVA sensitization group. Conclusion : In summary, our result shows that herbal extracts(CP001 and CP002) could be potential candidates for the treatment of chronic atopic dermatitis.

  • We aimed to investigate any association between hepatitis C virus (HCV) infection and non-Hodgkin's lymphoma (NHL) in the view of cytokines that control inflammation/angiogenesis and their correlation with certain CD markers. NHL patients with or without HCV infection were studied. CD5, CD30, CD3, CD20 and CD45 were immunohistochemically evaluated. Plasma levels of vascular endothelial and platelet derived growth factors (VEGF, and PDGF), tumor necrosis factor (TNF-${\alpha}$), transforming growth factor (TGF-${\beta}$), interleukin-6 (IL-6), IL-8, IL-4, IL-12 and interferon gamma (IFN-${\gamma}$) were detected by enzyme-linked immunosorbent assay (ELISA). HCV+ve NHL patients showed a significant reduction in VEGF, PDGF, IFN-${\gamma}$, CD5 and CD45 and a significant increase in IL-12 and IL-8. In conclusion, there was a significant change in cytokine secretion and expression of CD markers in HCV+ve NHL patients. Based on our results, HCV infection in NHL patients requires more in-depth investigations to explore any role in lymphoma progression.

  • Purpose: The risk of cardiovascular disease (CVD) has been shown to be associated with systemic inflammation in obese adults with metabolic syndrome (MetS). The aims of this study were to evaluate the prevalence of MetS and its relation to inflammatory markers in obese Thai children. Methods: A cross-sectional study was conducted. Children with history of endogenous obesity, chronic diseases, drug ingestion, and any acute illness within 2 weeks prior to enrollment were excluded. Their fasting blood glucose (FBG) levels, oral glucose tolerance tests, insulin, lipid profiles, and selected inflammatory markers, including interleukin-6, tumor necrosis factor-alpha, and high-sensitivity C-reactive protein (hs-CRP) levels, were tested. Results: In this study, 58 obese Thai children (female, 20; male, 38) with a mean body mass index z score of $5.1{\pm}2.2$ were enrolled. The prevalence of MetS and prediabetes was 31% and 17.2%, respectively. None of the children had diabetes. FBG levels, 2-hour glucose levels, and lipid profiles were not statistically different between those with and without MetS. However, obese children with MetS had higher insulin levels and homeostasis model assessment of insulin resistance values. Elevated hs-CRP levels were found in 69% of the cases, although it was not statistically different between the 2 groups. Conclusion: We described a substantial prevalence of MetS in Thai obese children. Regardless of MetS status, two-thirds of the obese children had elevated hs-CRP level, indicating subtle ongoing inflammatory process. This chronic inflammation feasibly predisposes them to CVD in the future, even in children without MetS.

  • The aim of the present study was to prepare nanosample of fucoidan using lecithin as encapsulated material and to investigate the anticancer and immunomodulatory activity of nanoparticle in vitro. The nanoparticles have been characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM). Confocal microscopy confirmed the internalization of the fucoidan conjugates into the immune cells. The uptake of nanoparticles was confirmed with confocal microscopy demonstrating their localization in the cells. The anticancer activity was increased over 5-10% in different cancer cells of fucoidan nanoparticle as compare with fucoidan. The human B and T cells growth and the secretion of interleukin-6 and tumor necrosis factor-a from B cell were also improved by fucoidan nanoparticle because of the rapid absorption of nanoparticle into the cells as compare to fucoidan. At 0.6 mg/mL concentrations, the fucoidan nanoparticle showed better activity than 1.0 mg/mL concentration in T cell growth because the cells reached their saturation capacity. When the fucoidan was encapsulated in lecithin, its anticancer as well as its immunomodulatory activity proved to be superior from that of itself in pure form.
