Two protein-polysaccharide fractions, GLA and GLB, respectively, were prepared from the pileus of the fully grown carpophores and the tips of the growing carpophores of Ganod erma lucidum. At a dose of 100mg/kg/day ip, GLA and GLB inhibited the growth of sarcoma 180 solid tumor in ICR mice by 56.3% and 81.8%, respectively. In a flow cytometric (FCM) analysis, GLA and GLB enhanced the formation of lymphoblasts of BALB/c, splenic leukocytes at a concentration of 100 ${\mu}$g/ml, by 38.3% and 61, 3%, respectively. When ip injected into ICR mice, GLB exerted anti-leukopenic effect against cyclophospamide (75mg/kg, ip) in that the leukocyte counts of the peripheral blood of the normal and the cyclophosphamide-treated mice. respectively. was (11.1 ${\pm}$ 3.8) ${\times}$ 10$^3$ and (4.0 ${\pm}$ 1.8) ${\times}$ 10$^3$, while the GLB-cyclophosphamide treated mice showed a leukocyte count of (10.8 ${\pm}$ 5.1) ${\times}$ 10$^3$ CELLS/${\mu}$l. These results suggest that GLB is a promising candidate for an effective, cancer immunotherapeutic agent.

GLB1-related disorders comprise two phenotypically unique disorders: GM1 gangliosidosis and Morquio B disease. These autosomal recessive disorders are caused by b-galactosidase deficiency. A hallmark of GM1 gangliosidosis is central nervous system degeneration where ganglioside synthesis is highest. The accumulation of keratan sulfate is the suspected cause of the bone findings in Morquio B disease. GM1 gangliosidosis is clinically characterized by a neurodegenerative disorder associated with dysostosis multiplex, while Morquio B disease is characterized by severe skeletal manifestations and the preservation of intelligence. Morquio B disease and GM1 gangliosidosis may be on a continuum of skeletal involvement. There is currently no effective treatment for GLB1-related disorders. Recently, multiple interventions have been developed and there are several ongoing clinical trials.

GM1 gangliosidosis is a rare autosomal recessively inherited metabolic disease due to deficiency of ${\beta}$-galactosidase caused by mutations in the GLB1 gene. There have been three clinical subgroups in GM1 gangliosidosis, however it is difficult to differentiate because there is considerable overlap between classical phenotypes and clinical and imaging findings among the subgroups. Here, we report a Korean girl with type 2 GM1 gangliosidosis, who showed dysostosis multiplex and progressive neurological deterioration. Developmental regression was first noted at the age of 9 months, and she was diagnosed as GM1 gangliosidosis by ${\beta}$-galactosidase enzyme analysis and GLB1 mutation analysis at the age of 16 months.

In our search for natural products affecting blood circulation, the n-butanol fraction from whole plant of Glehnia littoralis Fr. Schm. (GLB) improved blood lipid parameters, and ameliorated obesity in high-fat-diet (HFD)-fed C57BL/6 mouse model. Hyperlipidemia was induced by high-fat-diet for 4 weeks, and then GLB was orally administrated with 400 mg/kg/day for 4 weeks. GLB-treated group showed that the gain in body weight was significantly attenuated, the levels of total cholesterol and triglyceride significantly lowered on blood chemical analysis, and significantly prolonged the mice bleeding time when compared with those of HFD control group. Concomitantly, phytochemical composition of GLB was investigated by HPLC-hyphenated spectroscopy, and two major phenolic compounds, rutin and chlorogenic acid were identified in the GLB. Taken together, these results indicate that GLB has cardiovascular protective effects and could be a natural medicine candidate for the prevention of cardiovascular disease.

In order to investigate the immunomodulatory mechanism of Ganoderma lucidum, the effects of protein-bound polysacchride of Ganoderma lucidum on the proliferation and cytokine gene expression of mouse peritoneal macrophages was studied. In the macrophage proliferation assay using the BrdU labeling reagent, the GLA component extracted from Ganoderma lucidum or GLB from the bud of Ganoderma lucidum were added to the medium at the concentration of 0 to 256ug/ml. DNA synthesis of the macrophage was increased at 16ug/ml of GLA and 64ug/ml of GLB, respectively. In the reverse transcription polymerase chain reaction(RT-PCR), the cytokine(TNF, IL-1, and IL-12) gene and $\beta$-actin expression were also analyzed. 20$\mu\textrm{g}$/ml of either GLA or GLB increased TNF and IL-1 expression of the macrophages.

The viability of low-temperature sulfate reduction with hydrogen as electron donor was studied with a bench-scale gas-lift bioreactor (GLB) operated at $9^{\circ}C$. Prior to the GLB experiment, the temperature range of sulfate reduction of the inoculum was assayed. The results of the temperature gradient assay indicated that the inoculum was a psychrotolerant mesophilic enrichment culture that had an optimal temperature for sulfate reduction of $31^{\circ}C$, and minimum and maximum temperatures of $7^{\circ}C$ and $41^{\circ}C$, respectively. In the GLB experiment at $9^{\circ}C$, a sulfate reduction rate of 500-600 mg $l^{-1}d^{-1}$, corresponding to a specific activity of 173 mg ${SO_4}^{2-}g\;VSS^{-1}d^{-1}$, was obtained. The electron flow from the consumed $H_2$-gas to sulfate reduction varied between 27% and 52%, whereas the electron flow to acetate production decreased steadily from 15% to 5%. No methane was produced. Acetate was produced from $CO_2$ and $H_2$ by homoacetogenic bacteria. Acetate supported the growth of some heterotrophic sulfate-reducing bacteria. The sulfate reduction rate in the GLB was limited by the slow biomass growth rate at $9^{\circ}C$ and low biomass retention in the reactor. Nevertheless, this study demonstrated the potential sulfate reduction rate of psychrotolerant sulfate-reducing mesophiles at suboptimal temperature.

The present study was conducted ill. order to get the normal blood chemical values of Korean Jindo dogs. Blood samples were taken from 160(♂34, ♀126) healthy Jindo dogs in Jindo area. The results obtained in this study were summarized as follows: 1. The mean values of serum total protein(TP), albumin(Alb) and globulin(Glb) content, cholesterol(Chole), magnesium(Mg), calcium(Ca), inorganic phosphate(P), potassium(K), sodium(Na) and chloride(Cl) concentration in the group of less than one year old were 6.64(♂6.62, ♀6.64), 3.63(♂3.57, ♀3.65) and 3.00(♂3.05, ♀2.99)g/100ml, 170.97(♂166.46, ♀172.68)mg/100ml, 1.45(♂1.43, ♀1.46), 5.76(♂5.62, ♀5.81), 4.80(♂4.95, ♀4.75), 4.84(♂4.72, ♀4.89), 148.93(♂148.79, ♀148.98) and 110.22(♂110.42, ♀110.14)mEq/L, respectively, whereas the TP, Alb and Glb content, Chole Mg, Ca, P, K, Na and Cl concentration in the group of one year old and more were 6.88(♂6.84, ♀6.89), 3.65(♂3.63, ♀3.66) and 3.23(♂3.21, ♀3.23)g/100ml, 167.48(♂173.80, ♀166.48)mg/100ml, 1.40(♂1.36, ♀1.40), 5.69(♂5.53, ♀5.71), 4.62(♂4.73, ♀4.60), 4.88(♂4.90, ♀4.87), 149.86(♂149.60, ♀149.90) and 110.03(♂110.70, ♀109.92)mEq/L, respectively. The ratios of mean serum albumin to globulin(A/G), calcium to inorganic phosphate(Ca/P) and sodium to potassium(Na/K) in the group of less than one year old were 1.21(♂1.17, ♀1.22), 1.20(♂1.14, ♀1.22) and 30.77(♂31.52, ♀30.47), respectively, whereas the A/G, Ca/P and Na/K in the group of one year old and more were 1.13(♂1.13, ♀1.13), 1.23(♂1.17, ♀1.24) and 30.71(♂30.53, ♀30.78), respectively. 2. The mean values of Alb content, Mg, Ca and K concentration, A/G and Ca/P ratio appeared to be higher in the female than in the male, whereas the reverse was the case with P concentration. No differences were found between male and female in the TP and Glb content, Chole, Na and Cl concentration and Na/K ratio. 3. The mean values of Glb content appeared to be higher in the group less than one year old than in the group of one year old and more, whereas the reverse was the case with A/G ratio. The mean values of TP and Alb content and Ca/P ratio in the age groups less than one year tended to increase with aging, whereas the reverse was the case with Ca and P concentration. No differences were found between age groups in the Mg, K, Na and Cl concentration and Na/K ratio.

The effects of Lactobacillus buchneri 40788 and buffered propionic acid on preservation, intake and digestibility of alfalfa (Medicago sativa) and timothy (Phleum pratense) hay were investigated. During baling, forages were treated with L. buchneri 40788 (1.2${\times}$10$^6$ CFU/g) as a liquid (LLB) or as a granular preparation (GLB), with buffered propionic acid (10 mL/kg, BPA), or left untreated (control). Triplicate 500 kg round bales of each treatment were put up at two moisture levels for each forage: 17%${\pm}$0.33% and 20%${\pm}$0.30% for timothy and 17%${\pm}$0.20% and 19%${\pm}$0.27% for alfalfa (mean${\pm}$SD). Bales were sampled for chemical and microbiological analyses after 0, 30 and 60 d of storage. Compared to controls, all preservatives reduced (p<0.05) heating of both forages at all moisture levels with the exception of alfalfa baled at 19% moisture. After 60 d of storage, GLB reduced (p<0.05) moulds in 17% timothy hay as compared to other treatments, but at 20% moisture, moulds were reduced in LLB- and BPA-treated timothy as compared to controls. In alfalfa at 17% moisture, total bacteria were lower (p<0.05) in GLB-treated bales than LLB or control bales, but yeast and total bacteria were only reduced in BPA-treated alfalfa at 19% moisture. In situ DM disappearance of timothy (both moisture levels) and alfalfa (19% moisture level) increased (p<0.05) with LLB treatment compared to control. Digestibility of both forages did not differ (p>0.05) among treatments, however, voluntary DM intake of LLB-treated timothy (1.32 kg/d) was 22.3% higher (p<0.05) than control, and 14.1% higher than BPA-treated timothy. Treating timothy and alfalfa hay with L. buchneri 40788 or buffered propionic acid may improve the nutritive value of the hay when baled at 17 to 20% moisture.

Objective: This study was conducted to evaluate the effects of concentrate level and chromium-methionine (Cr-Met) supplementation on the growth performance, carcass characteristics, meat quality, and fatty acid composition of Tan lambs. Methods: Sixty male Tan lambs (21±1.23 kg body weight) fed a finishing diet (concentrate-to-forage ratio: 35:65 [LC group] or 55:45 [HC group]) with daily Cr-Met supplementation (0, 0.75, or 1.50 g) were used in a completely randomized design with a 2×3 factorial arrangement of treatments. Results: Lambs from the HC group had higher average daily gain, dry matter (DM) digestibility, dressing percentages, leg proportions, intramuscular fat (IMF) contents, and saturated fatty acid levels, but lower feed conversion ratios, globulin (GLB) and total protein (TP) concentrations, shear force, and monounsaturated fatty acid (MUFA) levels (all p<0.05). Cr-Met supplementation increased the DM digestibility, GLB and TP concentrations, rack and loin percentages, and cooking loss, but decreased the IMF contents and leg proportions (all p<0.05). Cr-Met supplementation at 0.75 g/d increased the conjugated linoleic acid (CLA) content in both the HC and LC groups (p<0.01). Significant interactions between the concentrate level and Cr-Met dosage were observed for MUFA (p<0.01) and polyunsaturated fatty acid (PUFA) (p<0.01) levels. Meat from the lambs fed an unsupplemented LC diet presented the highest PUFA and MUFA levels (p<0.01). However, the MUFA and PUFA levels decreased significantly with increasing Cr-Met supplementation levels in the LC group (p<0.01), whereas the opposite trend was seen in the HC group. Conclusion: The HC diet improved the growth performance of Tan lambs, increased their profitability by increasing leg and rack joint proportions, and improved meat quality by promoting an IMF content that was more visibly acceptable to consumers. Cr-Met supplementation at 0.75 g/d in a HC diet was the best choice and may be economically beneficial.

An experiment was conducted to determine the effects of different mycotoxin adsorbents including esterified glucomannan (EGM), hydrated sodium calcium aluminosilicate (HSCAS) and compound mycotoxin adsorbent (CMA) on performance, blood parameters, and liver pathological changes in broilers fed mold-contaminated feed. Two hundred and forty 10-day-old broilers were randomly assigned to one of the five dietary treatments including: i) control diet; ii) mold-contaminated diet; iii) moldcontaminated diet+0.05% EGM; iv) mold-contaminated diet+0.2% HSCAS; v) mold-contaminated diet+0.1% CMA. At 35-days-old, blood and liver tissue samples were collected for analysis. 0.1% CMA improved ADG and ADFI during 10-42 d compared to the moldcontaminated group (p<0.05). The mold-contaminated diet increased total white blood cell (WBC) number, haemoglobin (Hgb) concentration, hematocrit (Hct) level, serum aspartate aminotransferase (AST) and ${\gamma}$-glutamyl transferase (GGT) activities, and decreased red blood cell (RBC) number and serum globulin (GLB) and urea nitrogen (BUN) concentrations (p<0.05). The three mycotoxin adsorbents alleviated the alteration of RBC, WBC, Hgb and AST caused by the mold-contaminated diet. Furthermore, 0.1% CMA increased GLB concentration and decreased Hct level and GGT activity (p<0.05). Liver superoxide dismutase (SOD) activity was reduced, and myeloperoxidase (MPO) activity was increased by the mold-contaminated diet (p<0.05). Both EGM and HSCAS prevented the increase of MPO activity (p<0.05). Liver lesion, including severe vacuolar degeneration of hepatocytes, was observed in chicks fed the mold-contaminated diet. 0.05% EGM prevented these effects except for biliary hyperplasia and mild vacuolar degeneration. 0.2% HSCAS showed medium vacuolar degeneration of hepatocytes. Liver of broilers fed 0.1% CMA revealed a mild vacuolar degeneration. These results indicate that a mold-contaminated diet results in adverse effects on blood parameters and liver morphology. 0.05% EGM and 0.2% HSCAS partially alleviated the adverse effects. However, 0.1% CMA almost completely ameliorated the adverse effects.
