Protein-polysaccharide fractions, PJ-3 and PJ-4, were prepared from mycelial culture filtrate of an insect-born fungus, Paecilomyces japonica DGUM 32001, and subjected to a flow cytometrical analysis for their vivo antitumor and immunomodulating activity in ICR mice. When i.p. injected once daily for semen days at 100 mg/kg, PJ-4 exerted a strong antitumor activity showing the growth inhibition ratio of 85.1% against i.p. implanted sarcoma 180 cells, while PJ-3 showed only a weak activity. Moreover, PJ-4 signiscantly increased the expression level of CD25 (IL-2R $\alpha$-chain) as well as forward scatter (FSC) values of splenic CD8$^{8}$ T cells. It is also noteworthy that PJ-4 strongly induced the peritoneal exudate cells in the same experiment. In an in vitro study, PJ-4 slightly inhibited the growth of sarcoma 180 cells at the concentration of 50$\mu$g/ml or higher. These results strongly suggest that PJ-4 might exert its antitumor activity through immunostimulation as well as direct inhibitory activity on the tumor cells.

This study was carried out to investigate the antimicrobial and anti-inflammatory activities of ethanol extract from Glycyrrhizae radix (GR) and ethanol extract from Glycyrrhizae radix cultured with Paecilomyces japonica mycelium (GRPM). Antimicrobial activity was measured by paper disc diffusion assay and minimum inhibitory concentration (MIC). Anti-inflammatory activity was evaluated by measurement of NO production in LPS-stimulated RAW264.7 cells. For the results of the paper disc diffusion assay, GRPM showed high antimicrobial activities against Bacillus cereus, Listeria monocytogenes, and Staphylococcus aureus. In addition, the MIC of GRPM (100 ppm) was lower than that of GR (200 ppm) against L. monocytogenes. When the morphology of L. monocytogenes treated with GRPM was observed using a FE-SEM, the surface of cells treated with GRPM were damaged, and some parts of the cell wall were destroyed. The inhibitory effect on NO production in LPS-stimulated RAW264.7 cells was significantly increased by GRPM treatment. In conclusion, GRPM is superior to GR in terms of antimicrobial and anti-inflammatory activities.

The objective of this study was to investigate the effects of the feeding Cordyceps militaris extract on the improvement of the free fatty acid, lipid peroxide, creatinine and enzyme (creatine phosphokinase; CPK, lactate dehydrogenase; LDH, alkaline phosphatase; ALP, lecithin cholesterol acyltransferase; LCAT) activities in the sera of dietary hypercholesterolemic rats (SD strain, male) fed the experimental diets for 5 weeks. Concentrations of free fatty acid, lipid peroxide and CPK, LDH, ALP activities in sera were fairly reduced in the Cordyceps militaris extract administration group (CHE) than in the hypercholesterolemic diet group (CHD). However, no significance was found in the effect of an creatinine concentration among the groups. The LCAT activity in serum was increased in the Cordyceps militaris extract administration (CHE) than in the hypercholesterolemic diet group (CHD). From these results, Cordyceps militaris extracts were effective on the improvement of the lipid components and metabolic enzyme activities in sera of dietary hypercholesterolemic rats.

This study was conducted to investigate the quality of white pan breads as affected by various concentration of Cordyceps powder. Breads were prepared by addition of 0, 1, 2 and 3% of Cordyceps to flour of basic formulation. The moisture content of white pan breads decreased with increasing Cordyceps powder concentration. The pH of white pan breads also decreased with increasing Cordyceps powder concentration. In color values, with increase of Cordyceps powder concentration, L value decreased and a value increased in the crumb. The weights of breads cooled decreased with increasing Cordyceps powder concentration. The volume and height of dough decreased with increasing Cordyceps powder concentration. However, the specific volume and yield of dough were not significantly different among groups. The baking loss rate was higher in the breads with Cordyceps powder than in the control. In the texture characteristics, hardness and chewiness of breads significantly increased with increasing Cordyceps powder concentration and adhesiveness increased. In the sensory evaluation, when compared to the control, the breads added to 1% of Cordyceps powder was superior to in color and flavor, while was similar to texture and taste.

일반 상법으로 제조되는 코오지, 즉 밀 또는 대두에 A. oryzae만으로 제조하는 코오지에 Cordyceps sp.를 첨가하여 코오지의 품질에 미치는 영향을 조사하였다. A. oryzae만으로 제조하는 코오지에 Cordyceps sp.를 일정량 혼합 첨가하여 제국하여 생균수 및 포자수를 측정한 결과 48시간까지 급격히 증가했다. 이후 생균수 및 곰팡이의 포자수의 유의할만한 변화를 볼 수 없어 제국시간을 48시간 전후로 조정하는 것이 바람직한 것으로 나타났다. 또한 amylase 및 protease등의 효소역가를 측정한 결과 Cordyceps sp.를 첨가한 코오지가 Cordyceps sp.를 첨가하지 않은 코오지보다 효소역가가 높은 것으로 나타났다. 제국이 끝난 코오지에 대하여 맛, 향 및 색깔에 대하여 관능검사를 실시한 결과 A. oryzae와 Cordyceps sp.를 각각 0.5％(w/w)를 혼합 참가한 것이 더 좋게 나타났다.

Cordyceps sinensis has been clinically used for the treatment of recovering fatigue, promoting the production of body fluid and qi, resolving sputum and arresting cough. Recent studies showed that Cordyceps sinensis produced immune-modulatory, anticarcinogenic and antioxidative effects. But, there are lack of studies regarding the effects of Cordyceps sinensis on the asthma. So, this study was performed to investigate the oral administrated effects of this herb against the disease. Asthma was induced to Balb/c mouse by i.p. injection and aerosol immunization with ovalbumin, and the change of the eosinophil number in the bronchoalveolar avage fluid(BALF) was observed. Concentrations of Interleukine-4(IL-4), Interleukine-5(IL-5) in BALF and splenocyte were assessed by ELISA, ImmunoglobinG(IgG) and ImmunoglobinE(IgE) from serum were calculated by same method. We found that the effects of Cordyceps sinensis in asthma mouse was implicated in reductions of IL-4, IL-S released from type2 T helper (Th2) cell, and decreases of IgE from plasma cell. These findings suggest that Cordyceps sinensis can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.

The anti-diabetic effect of dried-silkworm Dongchunghacho water extracts was investigated in streptozotocin (STZ)-induced diabetic rats. Seven-week-old SD rats were randomly assigned to six groups: normal control (NC) group, diabetic control (DC) group, water extracts of Paecilomyces japonica grown on a dried-silkworm (PJ-DS, 50 mg/kg) group, PJ-DS (250 mg/kg) group, water extracts of Cordyceps militaris grown on a dried-silkworm (CM-DS, 250 mg/kg) group, and water extracts of dried-silkworm (DS, 250 mg/kg) group. These groups were orally provided with sample dissolved in water respectively for four weeks after an injection of STZ (60 mg/kg, ip) followed by identification of diabetic control (DC) group. After four weeks, body weight of all diabetic groups was significantly lower than that of the normal control (NC) group, but among diabetic groups there were no significant differences. Blood glucose levels of the PJ-DS (50 mg/kg), PJ-DS (250 mg/kg), CM-DS (250 mg/kg) and DS (250 mg/kg) groups were reduced compared to the DC group by 3.0 percent, 18.5 percent, 6.9 percent and 13.1 percent, respectively. Concentration of total cholesterol and triglyceride in blood plasma were to some degree decreased in PJ-DS (250 mg/kg) and DS (250 mg/kg) groups compared to the DC group. According to these results dried-silkworm Dongchunghacho water extracts (PJ-DS) boost protection against STZ-induced toxicity.
