We investigated whether an aqueous extract of Rehmannia glutinosa steamed root (RGAE) inhibits secretion of inflammatory cytolanes from primary cultures of mouse astrocytes. RGAE dose-dependently inhibited the $TNF-{\alpha}$ secretion by astrocytes stimulated with substance P (SP) and lipopolysaccharide (LPS). Interleukin-1 (IL-1) has been shown to elevate $TNF-{\alpha}$ secretion from LPS-stimulated astrocytes while having no effect on astrocytes in the absence of LPS. We therefore also investigated whether IL-1 mediated inhibition of $TNF-{\alpha}$ secretion from primary astrocytes by RGAE. Treatment of RGAE to astrocytes stimulated with both LPS and SP decreased IL-1 secretion to the level observed with LPS alone. Moreover, incubation of astrocytes with IL-1 antibody abolished the synergistic cooperative effect of LPS and SP. These results suggest that RGAE has an antiinflammatory activity on the central nervous system curing some pathological disease states.

The essential oil fraction was obtained from the underground parts o of Ligusticum chuanxiong (Umbelliferae) by steam distillation, and its main components, Z-ligustilide and butylidene phthalide, were isolated by column chromatography. Its essential oil fraction and the isolated main components were examined for effects on their anti-inflammatory properties in RAW 264.7 macrophage cells to develop a new natural anti-inflammatory drug. The results showed that the L. chuanxiong essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the production of nitric oxide significantly in lipopolysaccharide (LPS)-treated RAW 264.7 cells. LPS-induced interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-$\alpha$) production was also decreased in a dose-dependent manner. In addition, western blot analysis revealed that the L. chuanxiong essential oil fraction and also its main components, Z-ligustilide, and butylidene phthalide reduced the expression levels of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS).

A sesquiterpene was purified from Artemisia iwayomogi methanolic extract during the course of searching anti-inflammatory principle from medicinal plants. A sesquiterpene identified as armefolin inhibited the production of nitric oxide (NO) and attenuated inducible nitric oxide synthase (iNOS) protein level in lipopolysaccharide (LPS)-activated RAW 264.7 cells. Armefolin also down-regulated mRNA expressions of iNOS and pro-inflammatory cytokines, interleukin-$1{\beta}$ and interleukin-6 in LPS-activated macrophages. Moreover, armefolin suppressed the degradation of inhibitory-${\kappa}B{\alpha}$ (I-${\kappa}B{\alpha}$) in LPS-activated macrophages. These data suggest that armefolin from A. iwayomogi can suppress the LPS-induced production of NO and the expression of iNOS gene through inhibiting the degradation of I-${\kappa}B{\alpha}$. Taken together, armefolin from A. iwayomogi might be a candidate as promising anti-inflammatory agent.

Brain insults, including neurotrauma, infection, and perinatal injuries such as hypoxic ischemic encephalopathy, generate inflammation in the brain. These inflammatory cascades induce a wide spectrum of cytokines, which can cause neuron degeneration, have neurotoxic effects on brain tissue, and lead to the development of seizures, even if they are subclinical and occur at birth. Cytokines are secreted by the glial cells of the central nervous system and they function as immune system mediators. Cytokines can be proinflammatory or anti-inflammatory. Interleukin (IL)-$1{\beta}$ and IL-8 are proinflammatory cytokines that activate additional cytokine cascades and increase seizure susceptibility and organ damage, whereas IL-1 receptor antagonist and IL-10 act as anti-inflammatory cytokines that have protective and anticonvulsant effects. Therefore, the immune system and its associated inflammatory reactions appear to play an important role in brain damage. Whether cytokine release is relevant for the processes of epileptogenesis and antiepileptogenesis, and whether epileptogenesis could be prevented by immunomodulatory treatment should be addressed in future clinical studies. Furthermore, early detection of brain damage and early intervention are essential for the prevention of disease progression and further neurological complications. Therefore, cytokines might be useful as biomarkers for earlier detection of brain damage in high-risk infants.

Interleukin-2 (IL-2)는 많은 immunoenhancing lymphokine의 한 종류로서 lymphokine activiated killer (LAK) cell의 생성을 자극시켜 흑종의 종양세포를 죽인다고 알려져 있다. 최근 간종양에서 비장동맥 또는 간동맥으로 투여한 IL-2가 비장의 임파계를 자극하여 LAK cell을 생성하여 어느정도효과가 있음이 밝혀지면서, 여러가지의 투여 방법이 시도되고 있다. 그러나 각종의 투여 방법에서 실제로 투여한 IL-2의 인체내 분포에 관한 연구는 없다. 저자들은 비정맥과 간문맥에 이상이 없는 증례의 비동맥에 IL-2와 $^{99m}Tc-phytate$ 혼합물을 투여하고, IL-2의 생체에서의 비장과 간에 어떻게 분포하는지 알아보기 위하여 $^{99m}Tc$의 radioactivity를 계측하여 보았다. 6예의 간세포암과 3예의 위암으로부터의 전이성간암에서 동맥조영술적방법을 이용하여 초선택적 비장동맥에 투여한 IL-2와 $^{99m}Tc-phytate$ 혼합물이 비장 27%, 간73%의 분포를 보여 비장을 거쳐온 $^{99m}Tc$의 방사능이 간에 많이 침착함을 확인하였고 간과 비장이외의 부위 즉 골수, 복수 또는 폐장이나 늑막에는 전혀 방사능 분포가 없음을 알 수 있었다. 따라서 비정맥이나 간문백에 이상이 없는 증례에서 IL-2의 비장동맥 투여는 목적하는 바 IL-2의 생체내 분포를 이룩할 수 있을 것으로 사료된다.

The objective of the present study was to test the effect of platelet-activating factor (PAF) on rat alveolar macrophages. PAF alone did not stimulate superoxide secretion from alveolar macrophages. However, PAF $(10^{-5}\;M)$ significantly enhanced phagocytic activator zymosan-induced superoxide secretion from alveolar macrophages. This enhancement of PAF plus zymosan was 30% above the sum of the separate effects of PAF and zymosan. Similarly, PAF $1.3{\times}(10^{-5}\;M)$ was not a direct stimulant of alveolar macrophages, as it had no stimulatory effect on chemiluminescence generation, but potentiated zymosan-induced activation of chemiluminescence, i.e., 162% above the separate effects of each stimulant. PAF $10^{-16}{\pm}10^{-6}\;M$ also failed to stimulate IL-1 production from alveolar macrophages. In contrast, when both PAF $10^{-10}\;M$ and lipopolysaccharide(LPS) $(1 {\mu}g/ml)$ were added together at the initiation of the culture, IL-1 production was significantly increased indicating the potentiative effects of PAF on IL-1 production by alveolar macrophages. Collectively, these data suggest that PAF alone does not activate the release of bioactive products from alveolar macrophages. However, PAF appears to act as a priming mediator that potentiates stimuli-induced macrophage activity. These novel actions of PAF prove its role as a potent mediator of inflammatory and immune responses in the lung.

In this study, we examined transmission efficiency and expression level of the transgenes in the transgenic mice. The transgenic lines secreting a considerable amount of human lactoferrin(LF) thrombopoietin(TPO), interleukin-10(IL-10) into their milk were subjected to access the inheritance and maintenance of transgenic phenotype. They were bred through three generations. The transmission frequency for each generations(F9, F10, F11) of 3 lines was 38.03±10.43%(13/35), 48.33±3.76%(19/39) and 31.83±8.88%(9/28) in the LF line, 51.33±18.98%(20/38), 63.70±35.71%(12/20) and 29.57± 15.05%(8/26) in the TPO line, 38.27±17.74%(15/37), 47.47±29.88%(14/28) and 50.87±5.85%(14/28) in the IL-10 line, respectively.

The activity of N-acetylglucosamitnyltransferase(GnT) III and V on a Melanoma B-16 was examined after incubation with interleukin 1 (IL-1). While augumenting cell proliferation, IL-1 resulted in a decrease of GnT-III activity and an increase of GnT-V activities. Consistant with this, Melanoma B-16 cultured with IL-1 showed increased affinlity to Daturam stramonium lectin, which recognizes asialo-tri- and asialeo-tetra-antenery N-linked oligosaccharides. These results indicate that IL-1 modulate glycosyltransferase activity and the oligosaccharide structure of target cells. On the other hand, to investigate whether or not TKM-SG affect GnT-V gene expression in lung metastatic carcinoma, we used RT-PCR methods. TKM-SG treated cell lines showed low levels of secretion of GnT-V mRNA transcription as elucidated by RT-PCR. Thus, with together lower GnT-V activity levels in the medium, TKM-SG was highly effective for lung cancer metastasis treatment and it was concluded that the medicine can be used as a potent anti-lung cancer metastasis medicine.

The hawthorn fruit (Crataegus pinnatifida Bunge var. typica Schneider) is used as a traditional medicine in Korea. The objective of this study was to understand the mechanisms of the anti-inflammatory effects of the water fractionated portion of hawthorn fruit on a lipopolysaccharide (LPS)-stimulated RAW 264.7 cellular model. The level of nitric oxide (NO) production in the water fraction and LPS-treated RAW 264.7 cells were determined with an ELISA. The cytotoxicity of the water fraction and LPS was measured with an MTT assay. Expression of nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor (TNF)-${\alpha}$, interleukin 6 (IL-6), and interleukin $1{\beta}$ (IL-$1{\beta}$) mRNA were analyzed with a reverse transcription polymerase chain reaction (RT-PCR). The water fraction of hawthorn fruit was determined to be safe and significantly inhibited NO production in LPS-stimulated RAW 264.7 cells and suppressed COX-2, (TNF)-${\alpha}$, IL-$1{\beta}$, and IL-6 expression. The observed anti-inflammatory effects of the water fraction of hawthorn fruit might be attributed to the down-regulation of COX-2, (TNF)-${\alpha}$, IL-$1{\beta}$, and IL-6 expression in LPS-stimulated RAW 264.7 cells.
