Frankincense has been used as a traditional medicine for treating rheumatoid arthritis, dermatitis, and muscle pain. In this study, the anti-tuberculosis effects of Frankincense were evaluated in immune responses of macrophages. Frankincense methanol extract was not cytotoxic to the host. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction assay using human macrophage (THP-1) cells did not show cytotoxic effects or morphological changes with treatments of 31.3, 62.5, and 125 ㎍/mL Frankincense methanol extract (FRM). Inhibitory effects of Frankincense methanol extract on the growth of Mycobacterium tuberculosis in human macrophages were investigated. The immune response was measured by monitoring the levels of TNF-α and IL-1β in THP-1 cells with or without M. tuberculosis infection under Frankincense methanol extract treatment. Inflammatory cytokine levels and M. tuberculosis numbers were reduced in THP-1 cells treated with Frankincense methanol extract. Therefore, Frankincense methanol extract could be used as a potential anti-tuberculosis agent.

This study saw the anti-allergy effect by the immunity regulation action of Yanghyelyoonbotang (YHYBT) consists 12 kinds of herbal medicine agents. Consequently, YHYBT controlled the amount of secretion of various infla- mmatory cytokines, chemokine, monocyte chemotactic protein and histamine from cells (HMC-1, THP-1, EoL-1) stimulated by PMA, A23187 or HDM. 1. YHYBT did not show cytotoxicity on cultured human fibroblast cells under 250 ${\mu}g/m\ell$ concentration. 2. YHYBT suppressed IL-8, TNF-$\alpha$, IL-6 mRNA expression in the HMC-1 cell stimulated with PMA and A23187. 3. YHYBT significantly suppressed IL-6 release in the THP-1 and EoL-1 cell stimulated with HDM. 4. YHYBT significantly suppressed histamine release in the HMC-1 cell stimulated with PMA and A23187 in a dose-dependent. 5. YHYBT significantly suppressed $\beta$-Hexosaminidase release in the HMC-1 cell stimulated with A23187 in a dose-dependent. 6. YHYBT suppressed NF-$\kappa$B gene expression in the RBL-2H3 cell stimulated with PMA in a dose-dependent. These results suggested that YHYBT has suppressive effects on allergic reaction and pro-inflammatory cytokines in various cell lines through the regulation of immune system. YHYBT has potential to use as an antiallergic agents.

We investigated the effect of bovine lactoferricin (Lfcin-B) on cell cycle regulation and caspase activation in tumor cells. Treatment with Lfcin-B resulted in the production of intracellular reactive oxygen species (ROS) during apoptosis of THP-1 cells. Biochemical analysis revealed that Lfcin-B-induced apoptosis. the cell cycle arrest and caspase activation were completely abrogated by addition of an antioxidant such as N-acetylcysteine(NAC).

This study is to investigate the effects of Chinemys reevesii (CR) on allergic inflammation mechanism related chronic dermatitis. To investigate the effects of CR, we study inhibitory effect of CR on the levels of pro-inflammatory cytokines released from RAW 264.7 cell stimulated with lipopolysaccaride (LPS), and EoL-1, THP-1, Jutkat cell stimulated with Dermatophagoides pteronyssinus (DP), and LPS induced acute inflammatory BALB/c mouse model. CR reduced the levels of IL-$1{\beta}$ released from RAW 264.7 cell stimulated with LPS at 20 ug/ml, 10 ug/ml concentration. CR significantly reduced the levels of MCP-1 released from EoL-1 cell, IL-6 from THP-1 cell, and IL-4, IL-5, TNF-${\alpha}$ from Jutkat cell stimulated with DP at all the concentration. CR significantly reduced the levels of TNF-${\alpha}$, IL-6, IL-$1{\beta}$, in LPS induced inflammatory BALB/c mouse model, in a dose-dependent manner. These results suggested that CR has suppressive effects on pro-inflammatory cytokines in various inflammation related cell lines through the regulation of immune system. CR could be a therapeutic agent for treatment of chronic inflammatory dermatitis in the future.

The viruses of Herpes Simplex Virus 1 (HSV-1), Herpes Simplex Virus 2 (HSV-2) and Varicella-Zoster virus (VZV) which belong to the alpha herpes subfamily are important human pathogens. When eruptions were not fully developed from these viral infections, clinical diagnosis was not always easy and required virological confirmation test. The above viruses were reactivated in individuals who were compromised in immune competence for one reason or another. Polymerase chain reaction (PCR) enables rapid and sensitive detection of HSV and VZV DNAs. Its sensitivity was largely influenced by choice of primers. Authors conducted a study to detect of those three viruses in human specimens including vesicle fluid and joint fluid and serum using PCR methods. Primers used for this study were the general primer pair GPHV-RU which was known to amplify within the genes enjoying the highest degree of homology between UL15 of HSV and UL42 of VZV. PCR with primers hybridized pair GPHV-RU amplifies a 396 bp with THP-1 and HSV-2 standard strain DNA and 405 bp with VZV standard strain DNA. Restriction enzyme cleavage with HpaII and DdeI were used to detect and distinguish DNAs of THP-1 and HSV-2 and VZV. The purpose of this study was a rapid and easy detection of VZV and THP-1 or HSV-2 from various clinical specimens (vesicle fluid, serum and joint fluid) by PCR method. Used methods were: HSV PCR with primer 1, 2 and HpaII RE digestion; VZV nested PCR; HSV PCR with primer A, Band BssHII RE digestion. 1) In 33 cases (33/42, 78.6%) VZV was detected single or mixed infection from 42 clinical specimens which included vesicle fluid (5), serum form respiratory infected children (10), serum from immune suppressed adult cancer patients (7) and joint fluid from arthritis patients (20). 2) In 20 cases (20/42, 47.6%) HSV was detected singly or mixed infection and 19 of those cases were HSV-2 and 1 case was THP-1. 3) In 19 cases (19/42, 45.2%) VZV was singly detected which included serum from respiratory infected children (6 cases), joint fluid from arthritis patients (9 cases), vesicle fluid (2 cases) and serum form immunosuppressed cancer patients (2 cases). 4) HSV was singly detected in 6 cases (6/42, 14.3%) which included joint fluid from arthritis patients (5 cases) and serum form respiratory infected children (1 cases). 5) 14 cases of VZV and HSV mixed infection (14/42, 33.3%) were detected. They included vesicle fluid (3 cases), serum form immunosuppressed cancer patients (4 cases), serum from respiratory infected children (2 cases) and joint fluid from arthritis patients (5 cases). 6) HSV-1 and HSV-2 detection and typing by HSV PCR with primer A, Band BssHII RE digestion method was more sensitive and the results were easier to detect than on other method.

The anti-inflammatory activity of onion juices prepared from sulfur-fertilized onions was investigated by measuring the secretion of proinflammatory cytokines from human monocytes cultured under hyperglycemic condition. Human monocytic (THP-1) cells were cultured under normoglycemic (NG, 5.5 mM glucose) or hyperglycemic (HG, 25 mM glucose) conditions, with or without onion juice. Without onion juice, cell viability decreased significantly in the HG state for 48 h, compared to that in the NG state. With onion juice ($50-150{\mu}L$) treatment, the cell viability was not different from that under the NG condition, suggesting that onion juice prevented HG-induced monocytes cytotoxicity. While the HG condition in vitro significantly induced TNF-${\alpha}$ release from THP-1 cells and its gene expression, onion juice ($50{\mu}L$) significantly suppressed them. This indicates that onion juice inhibited HG-induced cytokine production in monocytes. These results suggest that onion juice from sulfur-fertilized onions can be used for the prevention of diabetes and related diseases.

Little is known about the cardiovascular effects of Lycopene, an anti-cancer and anti-oxidative agent. In this study, we executed a series of experiments with vascular endothelial cells to disclose the cardiovascular functions of lycopene. From our in vitro experiments, lycopene was determined to act as a stimulant to induce endothelial cell proliferation and migration. In addition, lycopene was shown to inhibit lipopolysaccharide (LPS)-induced adhesion of THP-1 leukocytes to endothelial cells, as well as activating mitogen activated protein kinase (MAPK) family members, ERK, JNK and p38 MAPK. Both ERK and p38 MAPK were involved in lycopene-induced cell proliferation, while JNK was involved in lycopene-dependent cell migration. Taken together, lycopene activates MAPK family members which regulate cell proliferation and migration. Lycopene differentially blocks LPS-dependent adhesion for THP-1 to endothelial cells, indicating that lycopene is likely to regulate a variety of vascular functions.
