Some pharmacological activities of acanthoic acid, isolated from Acanthopanax koreanum root was investigated in animals. It is revealed that the compound had analgesic and anti-inflammatory activities without actions on central nervous system and showed inhibition of lipid peroxidation. The anti-inflammatory activity might be related to inhibition of prostaglandin E$_2$ synthesis in exudates of inflammation.

Flavonoids are well-known anti-inflammatory agents that exert their effects via a variety of mechanisms including antioxidative action, inhibition of eicosanoid metabolizing enzymes and regulation of theexpression of proinflammatory molecules. In this review, synthetic approaches to obtain more useful flavonoid derivatives are summarized. Human clinical trials of flavonoid therapy are discussed. Through continual investigation to identify more potent and comparable flavonoids, new anti-inflammatory flavonoid therapy will be successfully launched, especially for the treatment of chronic inflammatory disorders.

This study was conducted to verify the availability of immature persimmon ethanol extract (IPEE) as a natural and functional ingredient in protecting inflammation and allergy of skin based on the mechanism. The major content analysis, antioxidant activities, anti-allergic activity, anti-inflammatory effect, and safety related to irritation of IPEE were evaluated. The gallic acid content per 10 mg/mL of IPEE was 0.522% (5.22 mg/g). The total polyphenol and flavonoid contents were 428.3 mg/g and 31.1 mg/g, respectively. In ABTS+ activity, DPPH ability and SOD-like activity, it showed a concentration-dependent increase, which indicated IPEE has excellent antioxidant activities. As for the anti-allergy test in RBL-2H3 cells, the IPEE showed a decrease in β-hexosaminidase secretion as the concentration increases, and IPEE tended to decrease IL-4 secretion in all RBL-2H3 cells compared to the IgE + HSA group. IPEE showed good anti-inflammatory effect in RAW 264.7 cells by decrease of NO production and inflammation cytokines (TNF-α and IL-6). Also IPEE showed non-irritant in BCOP assay. By the results of this study, the IPEE containing high tannins, had good antioxidant, anti-allergic, and anti-inflammatory effects, which indicated that the immature persimmon is considered to be a useful for the development of related functional ingredients.

Chronic inflammation plays a critical role in the development of obesity-associated metabolic disorders such as insulin resistance. Obesity alters the microenvironment of adipose tissue and the intestines from anti-inflammatory to pro-inflammatory, which promotes low grade systemic inflammation and insulin resistance in obese mice. Various T cell subsets either help maintain metabolic homeostasis in healthy states or contribute to obesity-associated metabolic syndromes. In this review, we will discuss the T cell subsets that reside in adipose tissue and intestines and their role in the development of obesity-induced systemic inflammation.

This study investigated the effects of triamcinolone acetonide by iontophoretic transdermal drug delivery on anti-inflammatory action into the rats and which had carrageenan-induced hyperalgesia and edema in the feet, trauma-induced tissue damage in the thigh. Each group was treated under the fellowing conditions. 1. Group I : Control group 2. Group II : Application of direct current 3. Group III : Application of 0.1$\%$ triamcinolone acetonide solution 4. Group IV : Iontophoresis of 0.1$\%$ triamcinolone acetonide solution The degree of anti-inflammation was evaluated by the paw withdrawal latency, the change in volume of foot the change of paw edema, histological change in rats. 1. In paw withdrawal latency, group IV showed the most significant therapeutic effect than the other groups at 0, 3, 6 and 9 hours(p < 0.001). 2. In paw edema experiment in the foot, group IV showed the most significant effect than group I at 0, 3, 6 and 9 hours. It meant that there was effective anti-inflammatory reaction in group I (p < 0.001). 3. In the light microscopic observation, group IV showed the most significant reduction of haemorrhage, hyperemia and infiltrative inflammation. From the results, the iontophoresis with triamcinolone acetonide is more effective than using each groups. It is one of the effective physical agent which delivered large molecular weight drug into the body. The continuous study is needed for many interesting issues of iontophoretic transdermal drug delivery in new future.

만성염증은 치주염, 대장염, 간염 및 관절염과 밀접한 관련성이 있다고 알려져 있다. 최근에 항염증제가 해양자원으로부터 개발되고 있다. 본 연구에서는 감태 (EC)가 항염증효과가 있다는 것이 발견되었다. 갈조류에 속하는 감태의 에탄올 추출물이 RAW 264.7 세포에서 tumor necrosis factor-${\alpha}$ interleukin-$1{\beta}$, interleukin-6 and prostaglandin $E_2$와 같은 염증매개체의 생성에 탁월한 효과를 나타내었다. 더욱이 reporter gene assay 및 western blot 분석 에 서 감태추출물은 대식세포에서 염증매개체의 발현을 조절하는 NF-${\kappa}B$ 전사인자의 불활성화를 통하여 항염증효과를 나타내었다. 뿐만 아니라 감태추출물은 만성염증에 중요한 역할을 하는 기질금속단백질의 활성을 억제 하였다. 이러한 결과는 갑태추출물이 만성염증을 억제하는데 잠재적으로 이용될 수 있다는 것을 암시하고 있다.

In our previous study, we have shown that berberine has both anti-adipogenic and anti-inflammatory effects on 3T3-L1 adipocytes, and the anti-adipogenic effect is due to the down-regulation of adipogenic enzymes and transcription factors. Here we focused more on anti-inflammatory effect of berberine using real time RT-PCR and found it changes expressions of adipokines. We hypothesized that anti-adipogenicity of berberine mediates anti-inflammtory effect and explored leptin as a candidate mediator of this signaling. We studied this hypothesis by western blot analysis, but our results showed that berberine has no effect on the phosphorylations of STAT-3 and ERK which have important roles on leptin signaling. These results led us to conclude that the anti-inflammatory effect of berberine is not mediated by the inhibition of leptin signal transduction. Moreover, we have found that berberine down-regulates NF-${\kappa}B$ signaling, one of the inflammation-related signaling pathway, through western blot analysis. Taken together, the anti-inflammatory effect of berberine is not mediated by leptin, and berberine induces anti-inflammatory effect independent of leptin signaling.

Bee venom (BV) has been used as a treatment for a wide variety of ailments such as inflammatory diseases in korean traditional medicine. Despite its well documented anti-inflammatory property, it has not been fully demonstrated regarding the influence of BV against Propionibactierium acnes (P. acnes), which promotes follicular inflammation (inflammatory acne). This study evaluated the anti-inflammatory property of BV against P. acnes in vivo. To induce inflammation in vivo using P. acnes, $1{\times}10^7$ CFU of living P. acnes were intradermally injected into the ear of mice. BV (1, 10, 100 ${\mu}g$) in vaseline was applied epicutaneously on the ear resulting in P. acnes-induced ear swelling and inflammation. Epicutaneous administration of BV with P. acnes decreased the number of infiltrated inflammatory cells and inflammatory cytokines in the ear, thereby relieving P. acnes-induced ear swelling and granulomatous inflammation, especially at the dose of 1 ${\mu}g$ of BV. In this report, we demonstrated the therapeutic effects of BV on P. acnes-induced inflammation in vivo using the mouse model. These data highlight the potential of using BV as an alternative treatment to the antibiotic therapy of acne vulgaris.

Neuronatin (NNAT) is known to regulate ion channels during brain development and plays a role in maintaining the structure of the nervous system. A previous in silico analysis showed that Nnat was overexpressed in the adipose tissue of an obese rodent model relative to the wild type. Therefore, the aim of the present study was to investigate the function of Nnat in the adipose tissue. Because obesity is known to systemically induce low-grade inflammation, the Nnat expression level was examined in the adipose tissue obtained from C57BL/6 mice administered lipopolysaccharide (LPS). Unexpectedly, the Nnat expression level decreased in the white adipose tissue after LPS administration. To determine the role of NNAT in inflammation, 3T3-L1 cells overexpressing Nnat were treated with LPS. The level of the p65 subunit of nuclear factor-kappa B ($NF-{\kappa}B$) and the activity of $NF-{\kappa}B$ luciferase decreased following LPS treatment. These results indicate that NNAT plays an anti-inflammatory role in the adipose tissue.
