The effects of liquid culture of Coriolus versicolor on weight gain, food intakes, food efficiency ratios, serum and hepatic lipid concentrations, serum protein levels and serum enzyme activities, were studied in growing male rats. Sprague-Dawley rats were given four different types of diets for a succeeding period of 5 weeks, respectively: a normal diet group (7% corn oil), a high fat diet group (7% corn oil+15% lard), a 20% or 30% C. versicolor diet groups (high fat diet+20% or 30% C. versicolor in water) according to the levels of C. versicolor supplementation. The body weight gains of the rats fed the 30% C. versicolor diets were lower than those in the rats fed high fat diet. The epididymal fat pad weight of the rats fed high fat diet and 20% or 30% C. versicolor diets were significantly higher than that of the rats fed normal diet. The concentrations of triglyceride in the serum and the liver of the rats fed the 30% C. versicolor diets were more significantly decreased compared to rats on the high fat diet. The concentrations of total cholesterol in the serum and the liver of rats fed the high fat diet, 20% and 30% C. versicolor diets were similar to those of rats fed the normal diet. The HDL-cholesterol concentration and the HDL-cholesterol/total-cholesterol ratio of the rats fed 20% and 30% C. versicolor diets were significantly lower than those of the rats fed high fat diet. But the antherogenic index of the rats fed 20% or 30% C. versicolor diets were significantly higher than those of the rats fed high fat diet. There were no differences in the activities of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and alkaline phosphatase in the serum among the experimental groups. These results showed that the 30% C. versicolor diet feeding decreased the triglyceride in serum and liver of the rats.

The effects of Paecilomyes japonica on weight gains, food intakes, food efficiency ratios, serum and hepatic lipid concentrations, serum protein levels and serum enzyme activities, were studied in adult male rats. Sprague-Dawley rats,35 weeks old, were given four different types of diets for a succeeding period of five weeks: either a normal diet (5% corn oil), a control diet (high fat; 5% corn oil + 15% lard), a PF diet (control diet + 3% fruiting body of Paecilomyes japonica), or a PM diet (control diet+.3% mycelium of Paecilomyes japonica). The body weight gains, hepatic weights and food efficiency ratios of rats fed the PF or PM diets were significantly lower than those fed the control diet, but were similar to those fed the normal diet. The concentrations of hepatic total lipids, cholesterol and triglyceric, and serum triglyceride, of rats given the PF or PM diets were significantly lower than those given the control diet. Hut the concentrations of total cholesterol, HDL-cholesterol, LDL-cholesterol and phospholipid in the serum of rats fed the control, PF or PM diets were significantly higher than those fed the normal diet. In the serum of rats fed the PF diet, the HDL-cholesterol/total cholesterol ratio was significantly higher and the atherogenic index was significantly lower than those fed the control diet, while such effect was not observed in rats fed the PM diet. The alkaline phosphatase activity in the serum of rats fed the control and PM diets was more significantly decreased compared to rats fed the PF and normal diet. No differences were noted in the weights of the pancreas, kidney and heart, the serum concentrations of glucose, hemoglobin and albumin, and the activities of GOT, GPT and ${\gamma}$-GTP, among the rats on all the experimental diets. In conclusion, the rats fed the PF or PM diets maintained normal body and hepatic weights. Despite of the high intake of fats in the PF and PM diets, the concentrations of hepatic total lipids, cholesterol and triglyceride, and serum triglyceride were decreased.
The technique of SCNT is now well established but still remains inefficient. The in vitro development of SCNT embryos is dependent upon numerous factors including the recipient cytoplast and karyoplast. Above all, the metaphase of the second meiotic division (MII) oocytes have typically become the recipient of choice. Generally high level of MPF present in MII oocytes induces the transferred nucleus to enter mitotic division precociously and causes NEBD and PCC, which may be the critical role for nuclear reprogramming. In the present study we investigated the in vitro development and pregnancy of White-Hanwoo SCNT embryos treated with caffeine (a protein kinase phosphatase inhibitor). As results, the treatment of 10 mM caffeine for 6 h significantly increased MPF activity in bovine oocytes but does not affect the developmental competence to the blastocyst stage in bovine SCNT embryos. However, a significant increase in the mean cell number of blastocysts and the frequency of pregnant on 150 days of White-Hanwoo SCNT embryos produced using caffeine treated cytoplasts was observed. These results indicated that the recipient cytoplast treated with caffeine for a short period prior to reconstruction of SCNT embryos is able to increase the frequency of pregnancy in cow.
Psychrophilic phytases suitable for aquaculture are rare. In this study, a phytase of the histidine acid phosphatase (HAP) family was identified in Morchella importuna, a psychrophilic mushroom. The phytase showed 38% identity with Aspergillus niger PhyB, which was the closest hit. The M. importuna phytase was overexpressed in Pichia pastoris, purified, and characterized. The phytase had an optimum temperature at $25^{\circ}C$, which is the lowest among all the known phytases to our best knowledge. The optimum pH (6.5) is higher than most of the known HAP phytases, which is fit for the weak acidic condition in fish gut. At the optimum pH and temperature, MiPhyA showed the maximum activity level ($2,384.6{\pm}90.4{\mu}mol{\cdot}min^{-1}{\cdot}mg^{-1}$, suggesting that the enzyme possesses a higher activity level over many known phytases at low temperatures. The phytate-degrading efficacy was tested on three common feed materials (soybean meal/rapeseed meal/corn meal) and was compared with the well-known phytases of Escherichia coli and A. niger. When using the same amount of activity units, MiPhyA could yield at least $3{\times}$ more inorganic phosphate than the two reference phytases. When using the same weight of protein, MiPhyA could yield at least $5{\times}$ more inorganic phosphate than the other two. Since it could degrade phytate in feed materials efficiently under low temperature and weak acidic conditions, which are common for aquacultural application, MiPhyA might be a promising candidate as a feed additive enzyme.

In medical selection of Daehan Education Insurance, We doubted that 140 cases(male 117 cases, female 23 cases) might have the fatty infiltration of the liver by ultrasonography. We examined the weight and the hypertension of 140 patients by biochemically analyzing the blood extracted under fasting according to the age-distribution. The results are as follows: 1. 90% out of them had body weight than normal subject. 34.29% out of them were hypertension patients and most of them were $30{\sim}39's$ and $40{\sim}49's$. 2. As compared with the normal subjects in serum lipid value, HDL cholesterol value was low, but total cholesterol, Triglyceride, phospholipid and total lipid value were significantly high. Especially the statistical value of Triglyceride was very significantly high. 3. Total abnormal rate of sGOT value in Liver function test is 34.43% and the mean value of it is 66 unit and the abnormal rate of sGPT value is all 3.14% and the value of it is 70 unit. 4. The abnormal rate of Alkaline phosphatase value is 9.29% and the abnormal rate of total Bilirubine value is 14.29%. As HBsAg positive rate is 2.14% and HBs Ab positive rate is 31.43%, the positive rate of HBsAg represents Lower positive rate than Korean mean value. 5. The abnormal rate of the fasting blood glucose is 15.00% and the abnormal rate of Blood sugar pc 2hrs is 30.71%. 6. The abnormal case of protein, Albumin, Globulin, BUN, craetinine and Hemoglobin value was not found to any of them and in the above liver function test except serum lipid value, the rate not showing the abnormal value represents 45.3%(male) and 52.17%(female).
Different herbs and spices have been used as feed additives for various purposes in poultry production. This study was conducted to assess the effect of feed supplemented with black pepper (Piper nigrum), turmeric powder (Curcuma longa), coriander seeds (Coriandrum sativum) and their combinations on the performance of broilers. A total of 210 (Cobb) one-d-old chicks were divided into seven groups of 30 birds each. The treatments were: a control group received no supplement, 0.5% black pepper (T1), 0.5% turmeric powder (T2), 2% coriander seeds (T3), a mixture of 0.5% black pepper and 0.5% turmeric powder (T4), a mixture of 0.5% black pepper and 2% coriander seed (T5), and a mixture of 0.5% black pepper, 0.5% turmeric powder and 2% coriander seeds (T6). Higher significant values of body weight gain during the whole period of 5 weeks (p<0.001) were observed in broilers on T1, T3, T5, and T6 compared to control. Dietary supplements with T1, T2, T3, and T6 improved the cumulative G:F of broilers during the whole period of 5 weeks (p<0.001) compared with control. The dressing percentage and edible giblets were not influenced by dietary supplements, while higher values of relative weight of the liver (p<0.05) were obtained in T5 and T6 compared to control. The addition of feed supplements in T5 and T6 significantly increased serum total protein and decreased serum glucose, triglycerides and alkaline phosphatase concentrations compared with the control group (p<0.05). Broilers on T6 showed significant decrease in the serum glutamate pyruvate transaminase concentration (p<0.05) compared to control. The broilers having T5 and T6 supplemented feed had relatively greater antibody titre (p<0.001) at 35 d of age than control. It is concluded that dietary supplements with black pepper or coriander seeds or their combinations enhanced the performance and health status of broiler chickens.
Objective: The objective of this study was to investigate the effects of low doses of organic trace minerals (iron, copper, manganese, and zinc) on productive performance, egg quality, yolk and tissue mineral retention, and fecal mineral excretion of laying hens during the late laying period. Methods: A total of 405 healthy hens (HY-Line White, 50-week-old) were randomly divided into 3 treatments, with 9 replicates per treatment and 15 birds per replicate. The dietary treatments included feeding a basal diet + inorganic trace minerals at commercial levels (CON), a basal diet + inorganic trace minerals at 1/3 commercial levels (ITM), and a basal diet + proteinated trace minerals at 1/3 commercial levels (TRT). The trial lasted for 56 days. Results: Compared to CON, ITM decreased (p<0.05) egg production, daily egg mass, albumen height, eggshell strength, yolk Fe concentration, serum alkaline phosphatase activity and total protein, and increased (p<0.05) egg loss and feed to egg ratio. Whereas with productive performance, egg quality, yolk mineral retention, and serum indices there were no differences (p>0.05) between CON and TRT. The concentrations of Fe and Mn in the tissue and tibia were changed notably in ITM relative to CON and TRT. Both ITM and TRT reduced (p<0.05) fecal mineral excretion compared to CON. Conclusion: These results indicate that dietary supplementation of low-dose organic trace minerals reduced fecal mineral excretion without negatively impacting hen performance and egg quality.

This study was initiated in order to investigate the anticancer and immunomodulating activities of crude polysaccharides extracted in methanol, neutral saline, and hot water (hereinafter referred to as Fr. MeOH, Fr. NaCl, and Fr. HW, respectively) from the fruiting bodies of Panellus serotinus. Content of ${\beta}$-glucan and protein in Fr. MeOH, Fr. NaCl, and Fr. HW extracts of P. serotinus ranged from 22.92~28.52 g/100 g and 3.24~3.68 g/100 g, respectively. In vitro cytotoxicity tests, none of the various fractions of crude polysaccharides were cytotoxic against sarcoma 180, HT-29, NIH3T3, and RAW 264.7 cell lines at the tested concentration. Intraperitoneal injection with crude polysaccharides resulted in a life prolongation effect of 23.53~44.71% in mice previously inoculated with sarcoma 180. Treatment with Fr. HW resulted in an increase in the numbers of spleen cells by 1.3 fold at the concentration of $50{\mu}g/mL$ compared with control. Treatment with Fr. NaCl resulted in improvement of the immuno-potentiating activity of B lymphocytes by increasing the alkaline phosphatase activity by 1.4 fold, compared with control, at the concentration of $200{\mu}g/mL$. Among the three fractions, maximum nitric oxide ($13.48{\mu}M$) was recorded at $500{\mu}g/mL$ in Fr. HW. Production of tumor necrosis factor alpha, interleukin-$1{\beta}$, and interleukin-6 was significantly higher, compared to the positive control, concanavalin A, at the tested concentration. Therefore, treatment with crude polysaccharides extracted from the fruiting body of P. serotinus could result in improvement of antitumor activity.
This study was conducted to investigate the effects of dietary Allium hookeri on growth performance, bone strength, and blood biochemical profiles in growing broiler chickens. Twelve hundreds of one-day old Arbor Acres male broilers were divided into 6 treatments with 4 replicates and 50 birds per replicate (n=200 chicks/treatment). Chickens fed basal diet (Control), basal diet with commercial X (Positive control) at 0.05% of diet, or each one of the experimental diets (L3, L5, R3, R5) supplemented with the powder of A. hookeri leaf or root at 0.3 and 0.5% of diet respectively for 5 weeks. At the 5th week of feeding the diets, body weight, tibia strength, and blood biochemical profiles including antibody titers were measured. Dietary A. hookeri (L3, L5, R3, R5) significantly increased final body weight than the control group. And the dietary leaf of A. hookeri effectively increased the growth performance than dietary root of A. hookeri. Interestingly dietary leaf of A. hookeri improved tibia strength than the control group and L3 showed the highest value. The antibody titers against infectious bursal disease (IBD) increased with the addition of dietary leaf of A. hookeri compared with positive control, R3, and R5 groups. But there was no significant difference in serum biochemical parameters such as albumin, globulin, glucose, cholesterol, Ca, P, total protein, total bilirubin, alanine aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase. These results suggest that A. hookeri can be used as a good supplement to improve growth performance and health by increasing bone strength and antibody titer against IBD without any anti-nutritional or toxic effects in growing broilers.

To prevent and treat the osteoporotic fracture, more attention should be paid in old age patients. Osteoclast which has ability to bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Rubi Fructus has been widely used in Oriental medicine. Extracts of the leaves and fruit of Rubus species have been used in various countries as natural remedies to treat diabetes, infections, colic, and burns. However, the effect of extract of Rubi Fructus (fruit of Rubus coreanus Miq.) in osteoclast differentiation remains unknown. Thus, we evaluated the effect of Rubi Fructus on receptor activator of nuclear factor-kB ligand (RANKL)-induced osteoclast differentiation. Here we found that Rubi Fructus significantly inhibited osteoclast differentiation induced by RANKL. Rubi Fructus suppressed the activation of p38 pathway and NFkB in bone marrow macrophages (BMMs) treated with RANKL. Also, Rubi Fructus significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Rubi Fructus greatly inhibited the protein expression of c-fos and NFATc1. especially in the case of NFATc1 expression, a master transcription factor of the differentiation of osteoclasts is very important step for osteoclastogenesis. Taken together, our results demonstrated that Rubi Fructus may be useful treatment option of bone-related disease such as osteoporosis and rheumatoid arthritis.
