  • The objective of this study was to examine the effects of antioxidant vitamins on the cellular oxidant damage by observing the mitogenicity in the mouse spleen and the strand breaks of DNA in mouse blood induced by $AFB_2$. Intraperitoneal(i.p.) injections of vitamin C(VC) of 10 mg/kg and vitamin E(VE) of 63.8 mg/kg were repeatedly administered to male ICR mice of 6 weeks old at intervals of 4 times every 2 days. After one hour vitamin treatments, $AFB_1$ of 0.4 mg/kg was injected into the $AFB_2$ plus vitamin treated groups in the same way. On the other hands, into the $AFB_2$ only treated group, only $AFB_2$ was injected without vitamins in the same method as above. The results of the experiment are as follows ; as regard to comet assay, DNA strand breaks were clearly present and they formatted a typical comet tail in the mice blood of the $AFB_2$ only treated groups. However, comet tails apparently disappeared in $AFB_2$ plus antioxidant vitamins treated groups since oxidant damage was controlled in an almost similar level to the control group. Mitogenicity of the spleen also showed a similar tendency as before, and these differences were more remarkably observed in the reaction against Con-A, which is a T-cell mitogen. In these data, the statistical significance was p<0.01. The LDL and VLDL levels were 408.72, 504.47 mg/dl respectively in the $AFB_2$ only treated groups. Compared with the $AFB_1$ only treated groups, those of $AFB_2$ plus antioxidant vitamin treated groups decreased to 272.06(VC), 305.28 mg/dl(VE), respectively. On the other hand, HDL levels were diminished to 32.60, 29.60 mg/dl in $AFB_2$ only treated groups, compared to 42.23, 41.14 mg/dl in the $AFB_2$ plus antioxidant vitamins treated groups. But, blood glucose levels were not statistically significant.

  • Hot water-extracts prepared from Cordyceps militaris of silkworm pupa (CMP) or Cordyceps militaris of silkworm larva (CML) were tested for tumor growth inhibitory and immunomodulatory activities in ICR mice bearing sarcoma-180 cells solid tumor, and compared with those of the known compound, cordycepin, found in Cordyceps militaris. Mice were subcutaneously injected with sarcoma-180 cells, and i.p. injected with either saline (Control), 50 mg/kg or 100 mg/kg of CMP (CMP50 or CMP100, respectively), or CML (CML50 or CML100, respectively), or 1 or 2 mg/kg of cordycepin (C1 or C2, respectively) for 10 days. Mice injected with CMP50 or CMP100 showed a 47.3% or 57.6% inhibition in the solid tumor growth (P<0.05), while those injected with CML50 or CML100 exhibited a 35.5% or 37.1% reduction (p<0.05) in solid tumor size compared to the value for control mice treated with saline. Animals injected with corcycepin showed a 26∼30% inhibition in the solid tumor growth (P<0.05). Mice bearing solid tumor and injected with CMP or CML showed a significantly increased thymus weight (38∼44% increase), lymphocyte percentages of CD4+ T-cell, CD8+ T-cell, and NK-cell (63∼110% increase) in the spleen, and interleukin-2 excretion (33∼51% increase) by the isolated splenocytes compared to those in control mice (p<0.05). These results indicate that the anti-tumor activity of hot water extracts of Cordyceps militaris, raised on both silkworm pupa and silkworm larva, appears to be associated with their immunomodulatory activity, and these activities found in Cordyceps militaris are superior to those for the single compound, cordycepin.

  • This study was conduct to compare the efficacy to produce male and female somatic cloned piglets. Maturation of porcine COCs was accomplished by incubation in NCSU-23 medium supplemented with 0.6 mM cysteine, 10% porcine follicular fluid, 1mM dibutyryl cyclic adenosine monophosphate (dbc-AMP, Sigma, USA), and 0.1 IU/ml human menopausal gonadotrophin (hMG, Teikokuzoki, Japan) for 20h and then cultured without dbcAMP and hMG for another 18 to 24 h. Female and male fetal cells were isolated from each fetus, cultured in ES-DMEM medium containing 10% FCS. Enucleated oocytes were fused with fetal fibroblasts (passage 4 to 15). Reconstructed embryos were cultured in NCSU-23 with 4 mg/ml BSA under mineral oil at 39$^{\circ}C$ in 5% $CO_2$ in air. A total of 12,328 nuclear-transferred embryos (1- to 4-cell stage) were surgically transferred into 69 surrogate gilts. Three recipients aborted during the period of conception. Three gilts delivered eleven female piglets, and five recipients gave rise to birth 22 male piglets. The average birth weigh of the cloned piglets was 1.52 kg (1.38~1.83 kg) in female piglets and 0.84 kg (0.45~1.25 kg) in male piglets. Alive cloned pigs was seven in female piglets (63.6%) and four in male piglets (18.2%). The other two recipients is ongoing. This study suggests that female-derived fetal cell as a nuclear donor has more capability on production of cloned piglets than male.

  • The hepatotherapeutic effect of the extract of Lycii fructus has been studied in rats against $CCl_4$ induced liver toxicity. The rats were orally treated with $CCl_4$ (corn oil/$CCl_4$ 1:1, $1m{\ell}/kg$) and then $CCl_4$ ($0.5m{\ell}/kg$) administered four times for 2 weeks. The extracts of L. fructus have been administered every day for 2 weeks after the last $CCl_4$ injection. The experimental groups consisted of negative control (G1), positive control ($CCl_4$ alone; G2), extract of L. fructus (50 mg/kg; G3, 100 mg/kg; G4, 200 mg/kg; G5), respectively. There was a significant decrement to G2 on the serum level of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase in G5. Also, the content of thiobarbituric acid reactive substance, and phosphatidylcholine hydroperxidase, a marker of lipid peroxidation, in the liver were decreased significantly G5 and G4 compared with G2. Although, catalase or superoxide dismutase, antioxidant enzyme, in the liver were decreased significantly too, it would not be a good sign for the liver. In histopathological findings, such a hepatocellular vacuolar degeneration, lobular restructure, cellular infiltration, necrosis, and so on were shown severely in G2. However, G4 and G5 was shown a mild cytoplasmic vacuolation and inflammatory cell. In conclusion, as a protection against cell damage, lipid peroxidation and serum level, it suggested that the extract of Lycii fructus would have been a therapeutic effect of liver injury directly.

  • The physicochemical properties and antioxidant activities of fermented mulberry by lactic acid bacteria were investigated. The viable cell counts of lactic acid bacteria slowly increased up to 8.31 log CFU/mL. The pH and titratable acidity were 3.90 and 0.15%, respectively, after 24 h of fermentation. Color in terms of L and a values decreased, whereas b and ${\Delta}E$ values increased. The total anthocyanin contents of fermented mulberry (171.40 mg/100 g) was higher than that of mulberry (144.70 mg/100 g). The cyanidin-3-glucoside and cyanidin-3-rutinoside contents of fermented mulberry were 61.39 mg/100 g and 85.45 mg/100 g, respectively. Total phenolic and flavonoid contents of fermented mulberry (10.75 g/100 g and 5.02 g/100 g, respectively) was higher than those of mulberry (4.53 g/100 g and 1.77 g/100 g, respectively). The oxygen radical absorbance capacity of fermented mulberry was $292.94{\mu}M/g$. The 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity and superoxide radical scavenging activity of fermented mulberry at $250{\sim}2,500{\mu}g/mL$ were 17.40~58.21% and 32.63~87.34%, respectively. The ferric reducing antioxidant power and reducing power of fermented mulberry at $250{\sim}2,500{\mu}g/mL$ were $37.03{\sim}762.13{\mu}M$ and 0.12~0.74, respectively. The results suggest that mulberry fermented by lactic acid bacteria has potential as functional materials in food industry.

  • The purpose of this research was to investigate the effect of Sabaek-San(SBS) on the activity of immune cell and leukemia cell. The addition of SBS(1 ㎍/㎖) enhanced the proliferation of cultured-splenocytes and thymocytes. And also, administration of SBS(250, 500 mg/kg) accelerated subpopulation of splenic T lymphocytes in BALB/c mice. Administration of SBS eminently enhanced the production of IFN-γ, and IL-4. The treatment of high dose of SBS inhibit the proliferation of Jurkat cells and dose-dependently increased the apoptosis of cultured-Jurkat leukemia cells. These results suggest that SBS have a cell mediated immuno-regulatory effect.

  • Objectives : In this study, we investigated anti-allergic effect of Okbyeongpungsan-Hap-Changijasan (KOB01) in allergic rhinitis(AR) experimental animals and mast cells. Methods : The potential anti-allergic effect of KOB01 was investigated in a rat model of compound 48/80-induced systemic anaphylactic shock and a mouse of ovalbumin(OVA)-induced AR, and human mast cell line, HMC-1 culture. Each animals were divided into four groups: normal, control, KOB01-treated(100 and 200 mg/kg) and anti-histamine drug, dosodium cromoglycate (DSCG)-treated(50 mg/kg). Animals were orally treated with KOB01 and DSCG and intraperitoneally injected with compound 48/80($10\;{\mu}g/kg$) or sensitized with 0.1% OVA. The mortality and serum histamine levels were measured in compound 48/80-induced anaphylatic rats. The histological changes in nasal mucosa were investigated in OVA-induced AR mice. Also, mast cell degranulation was observed in compound 48/80-stimulated HMC-1 cells. Results : KOB01 increased mortality and significantly decreased serum histamine levels in compound 48/80-induced anaphylatic rats. The abnormal histological changes such as expansion of grandular cells and hypertrophy of epithelium in nasal mucosa of OVA-induced AR mice was improved by KOB01 treatment nearby a normal group. Therefore, KOB01 inhibited compound 48/80-induced degranulation in HMC-1 cells. Conclusions : These results indicate that KOB01 decrease allergic response through suppressing the mast cell activation in AR and suggest a potential role for KOB01 as a source of anti-allergic agents for use in allergic disorders including of AR.

  • In order to examine the functionality of broccoli sprout (Brassica oleracea, BS), solvent extracts were prepared and their anti-oxidative and immunomodulating activities were compared with those of broccoli (B). EtOH extracts (E) were potently higher than hot-water extracts (HW) in the antioxidant contents and radical scavenging activity. In particular, the total polyphenolic contents in addition to ABTS and DPPH radical scavenging activity were significantly higher in EtOH extract of broccoli sprout (BS-E; 9.15 mg GAE/g, 4.52 mg AEAC/g, and 1.14 mg AEAC/g) compared with that of broccoli (B-E; 7.83 mg GAE/g, 3.63 mg AEAC/g, and 0.97 mg/AEAC/g). Whereas, total flavonoid content was significantly higher in B-E (1.60 mg QE/g) than BS-E (1.43 mg QE/g). Anti-inflammatory activity was investigated using LPS-induced cell line model at a concentration of $10{\sim}100{\mu}g/mL$, in which all solvent extracts of both broccoli sprouts and broccoli were not toxic to RAW 264.7 cell lines. In anti-inflammatory activity of broccoli sprouts, EtOH extracts also showed significantly more potent activity than hot-water extracts in all sample concentrations tested. In addition, BS-E ($100{\mu}g/mL$) inhibited nitric oxide (NO) and IL-6 production to 60.9% and 68.9% compared with the LPS inflammation group (without extracts), whereas B-E inhibited 49.6% and 54.9%. On the other hand, in immunostimulating activity by splenocytes and macrophages, hot-water extract showed significantly higher activity than EtOH extract. Especially, BS-HW stimulated the splenocyte proliferation (1.2-fold against saline group) and IFN-${\gamma}$ production (264.39 pg/mL) at $100{\mu}g/mL$, and the production of IL-6 (1.33-fold), IL-12 (1.09-fold) and TNF-${\alpha}$ (1.49-fold) from macrophages was also significantly enhanced over broccoli. In conclusion, broccoli sprouts showed more potent anti-oxidative, anti-inflammatory and immunostimulating activity than broccoli, suggesting the possibility of using broccoli sprouts as functional food materials.

  • The production and secretion of growth hormone (GH) in the anterior pituitary gland can be induced by several natural products to control cell proliferation, differentiation, and migration. To investigate whether Chungkookjang (CKJ) produced by the fermentation process affects GH-related metabolism, the secretion and the response of GH were observed in pituitary cells and GH target cells. Among six CKJs manufactured by different strains of glycine max, only three CKJs, including Daewon (DW), Daepung (DP), and Taegwang (TG), induced GH secretion from GH3 cells at 5.0 mg/ml concentration. There were no significant changes detected in the viability of any of the cells treated with these CKJs. In addition, the increase in GH secretion from the GH3 cells was dependent on the concentration of the three types of CKJs. The proliferation of cell lines, including MG63 and HepG2 cells, that originated from those derived from the GH target organs was significantly activated by treatment with the GH-containing conditional medium (GCM) harvested from the three CKJ-treated GH3 cells, although their induction rate was different from each other. In these cells, p-STAT5 was maximally translocated into the nucleus of MG63 cells 30 min after DW treatment, while it was translocated in HepG2 cells at 60 min. These results suggest that these three types of CKJ could enhance the secretion of GH, as well as the GCM-derived response, in the two target organs.
