Objective: Atopic dermatitis is the most common chronic inflammatory skin disease in childhood. Phellinus linteus, an orange color mushroom, has been used as a traditional herb medicine for years. Recent preliminary animal experiments suggest that Phellinus linteus grown on germinated brown rice is effective in chronic inflammatory disease. The aim of this study was to evaluate the efficacy of Phellinus linteus grown on germinated brown rice in the treatment of atopic dermatitis(AD). Methods: 35 patients, 2 to 14 years of age, with mild to moderate AD were treated with Phellinus linteus grown on germinated brown rice powder per oral, $6{\sim}12g$/day adjusted by the body weight, divided three for up to 12 weeks without other treatment. The mean age of patients was 7.3 years. The disease activity has been monitored by objective SCORAD index. The symptom score of the pruritus was measured by using a traditional visual analogue scale (VAS). In addition, the global assessments of clinical response were also monitored by patients or their parents. Results: After 12 weeks of the study, significant reductions in mean severity scores and mean symptom scores were observed. The mean objective SCORAD indices of 35 patients decreased from 25.31${\pm}$8.96 to 18.73${\pm}$13.89(p<0.05). And the mean symptom score of pruritus assessment decreased from 7.37${\pm}$1.33 to 4.6${\pm}$2.3(p<0.05). The patient's global assessment of clinical response were also improved through the period of treatment(p<0.05). Conclusions: Phellinus linteusgrown on germinated brown rice may play a role in the treatment of mild and moderate AD in Children.

Thirty five AD patients were treated with Phellinus linteus grown in germinated brown rice(PB) p.o., at 6, 9, and 12 g/day to the patients with their body weight for 12 weeks. A significant reduction in mean severity scores and mean symptom scores was observed after PB treatment. The mean SCORAD indices pre and post PB treatment were $31.28{\pm}10.01$ and $22.39{\pm}15.59$ (p<0.05), respectively. And the mean symptom score of pruritus assessment decreased from $7.37{\pm}1.33$ to $4.6{\pm}2.34$ (p<0.05) after PB treatment. These results suggest that PB shows alleviation of atopic dermatitis symptoms.

The present study describes the preliminary evaluation of the anti-inflammatory activities of Phellinus linteus (PL) and Phellinus linteus Grow in Germinated Brown Rice (BRPL). In order to effectively screen for anti-inflammatory agents, we first examined the extracts' inhibitory effects on the expression of pro-inflammatory cytokines activated with lipopolysaccharide. Moreover, we examined the inhibitory effects of the PL and BRPL extracts on pro-inflammatory factors such as NO, iNOS, $TNF-{\alpha}$ and $IFN-{\gamma}$ in murine macrophage RAW 264.7 cells. NO production and iNOS expression was significantly augmented in LPS treated cell, the production of NO and iNOS was greater in the BRPL than in the PL group. In addition, protein and mRNA levels of $TNF-{\alpha}$ and $IFN-{\gamma}$ in BRPL showed relatively more potent pro-inflammatory-activity inhibition compared to that of PL. These results suggest that BRPL may have significant effects on inflammatory factors, and may be a potential anti-inflammatory therapeutic materials.

The purpose of this study was to develop a muffin recipe that included germinated brown rice powder soaked in a mycelial culture broth of Phellinus linteus (GBRP). Muffins were made using various quantities of GBRP, butter, and milk. An assessment was conducted using the response surface methodology (RSM), which included 16 experimental points with three replicates for the three independent variables: GBRP, butter, and milk. The physical and chemical evaluation using the RSM showed no significant differences; whereas the hardness, cohesiveness, springiness, gumminess, and chewiness indicated significant differences in the relationships between the factors (p<0.05). The sensory evaluation using the RSM was highly effective in describing the relationships between overall acceptability and taste (p<0.001). Thus, the optimal combination of ingredients in a GBRP muffin, as assessed with numerical and graphical methods, was 84.041 g GBRP, 110.224 g butter, and 80.0 g milk.

This study investigated the effects on the biological activities of germinated brown rice soaked in mycelial culture broth of Phellinus linteus. The level of free amino acid was higher in the GBRP extract than those of BR and GBR. The major free amino acids were alanine, valine, isoleucine and methionine in both extracts. The level of ${\gamma}$-aminobutyric acid (GABA) was also increased significantly in the GBR and GBRP. Antioxidant activities of methanol extract of BR, GBR and GBRP were measured by using DPPH radical scavenging and SOD-like activity. Antioxidant activities showed the highest level of 83% and 76% when 100 mg/ml GBR and GBRP, respectively. Stimulation of the macrophages RAW264.7 cells with lipopolysaccharide (LPS) resulted in increased production of nitric oxide (NO) in the medium. However, the methanol extract of GBR and GBRP showed marked inhibition of NO synthesis in a does-dependant manner. These results showed that GBR and GBRP were significant role for activation of immune system in the pathogenesis of inflammatory diseases.

The purpose of this study was to examine the qualities of optimized muffins with germinated brown rice soaked in mycelial culture broth of Phellinuslinteus (GBRP) using response surface methodology. Firstly, general compositions of optimized muffins with GBRP were higher than that of control and total sugar contents were similar. However, the total free amino acid and constitutional amino acid contents except for GABA were lower than those of control. Starch hydrolysis in control was higher than in optimized muffins with GBRP, whereas protein digestibility and protein efficiency ratio were not. The weights of optimized muffins with GBRP were higher than that of control (p<0.01), whereas height (p<0.01) and pH (p<0.001) were similar. The hardness (p<0.05) and chewiness (p<0.05) of optimized muffins with GBRP were higher compared to control; adhesiveness, springiness, and gumminess were similar, but cohesiveness (p<0.01) was not. The flavor (p<0.05) and taste (p<0.01) of optimized muffins with GBRP were higher than those of control; appearance, texture and overall acceptability were similar, but color (p<0.05) was not. The total polyphenol contents (p<0.01), DPPH radical scavenging activity (p<0.01), and superoxide dismutase-like activity (p<0.05) of optimized muffins with GBRP were higher than those of control, but nitrite scavenging activity was similar.
