Purine has been identified in the preparation of follicular fluid and shown an activity in maintaining oocyte meiotic arrest. Therefore this study was performed to examine the inhibitory effect of purine on germinal vesicle break down(GVBD) in the presence and absence of human fetal cord serum(HFCS) or human mature follicular fluid(HMFF), as a protein source, in vitro culture. Immature oocytes(GV stage) were collected from ovaries of 21∼28 days old ICR mice by puncturing the antral follicles with a fine needle, at 48 hrs after PMSG injection. Some of the oocytes were denuded by drawing the cumulus-enclosed(complex) oocytes in and out of a pasteur pipet. Complex oocytes and denuded oocytes were cultured 3 hrs. in T6 media containing 0.75mM adenosine or/and 4mM hypoxanthine, with HFCS or HMFF. Their GVBD rates were observed at every 1 hr. during the culture time. Both adenosine and hypoxanthine have shown a time-dependent inhibitory effect on GVBD in complex and denuded oocytes and the inhibitory effect was maximized in culture medium containing hypoxanthine and adenosine. HFCS and HMFF increased the GVBD rates in the presence of the purines, thus HFCS and HMFF may contain a factor that could reverse the inhibitory effect of purines. Also complex oocytes were more sensitive to not only the inhibitory effect of purines but the promoting action of HMFF on GVBD than denuded oocytes. Therefore it was reconfirmed that granulosa cells play an important part in meiotic arrest and resumption.

When mice irradiated by neutron (Be) are fed with ginseng concentrate, ginseng powder, and adaptagen of which the major ingredient is ginseng alkaloid to neutron (Be source) irradiated mouse, the following results are obtained. 1. The 50% lethal dose (LD50) for the neutron irradiation were 4 days at 600 rad, 7 days at 500 rad, 16 days at 400 rad, 33 days at 375 rad, and 55 days at 350 rad. In thistest, the standard amollntofirradiation was set at 375 rad/8 min. 2. Some spots appeared in the tail of the neutron-irradiated mouse because of blood congestion, and some had its tip tails cut. But the group administered with adaptagen did not show any of these symptoms. 3. The neutron irradiated mouse showed darkening the color of their lung-chloasmas while none of the adaptagen group had this symptom. 4. The lung tissue of the neutron irradiated mouse showed an increase of the karyolysis and cytoplasmic vacuole. 5. When both neutron irradiation and the ginseng sllbstances were given to the mouse at the same day, the 50% lethal days were increased to 29-33 days for the group administered with ginseng extract. 67 days for the group given with the ginseng powder. and 80 days for the groilp arith the adaptagen. 6. The survival rate of those fed with adaptagen for 33 days before the neutron-irradiation was 100%, while the 50% lethal daysofthe group fed with ginsengextract were 39 days and that of the group fed with ginseng powder were 69 days. 7. The serum valued of ${\gamma}$-globulin, IgG, and albumin were returned to normal condition in the group fed with adaptagen for 33 days before the neutron-irradiation. But those of the group which were given the irradiation and the ginseng substances at the same day did not show such a recovery.

In order to know the mode of the action of gondotrophic hormone on the expansion of cumuli oophori, oocyte-cumulus complexes isolated from Graafian follicles of mice were stimulated to expand in vitro with human chorionic gonadotrophin (HCG), and the effects of puromycin and actinomycin D on the expansion were examined. THe complexes were cultured in medium TC 199 containing 10% bovine serum in the presence or absence of HCG and the inhibitors. Puromycin in the medium (0.5-4 $\\mu$g/ml) suppresseed the HCG-induced cumulus expansion dose-dependently. This effect of puromycin was reversible. Puromycin affected the complexes throughout the HCG-stimulating stage (3 hours) and hyaluronic acid synthesis stage (3-18 hours). Actinomycin D also inhibited the expansion of the cumulus from the concentration of 0.025 $\\mu$g/ml. But the effect of actinomycin D was not completely reversible and the drug appeared to give an irreversible damage to the complexes at 0.1 $\\mu$g/ml. From the above results, it is suggested that RNA or protein synthesis is involved in the process in which HCG stimulates the cumulus cells to expand therefore cAMP elevated by te gonadotrophin may control expansion at the transcriptional or translational level.

Purpose : This study was to investigate the anti-inflammatory effects of Kagamsunbanghwalmyungeum(KSBH) which has been medicated the patient such as breast abscess. Methods : In the study of anti-inflammatory effects, KSBH was investigated using cultured cells and a murine models. As for the parameters of inflammation, level of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cell(mLFC) and RAW 264.7 cells. Results : The cytotoxicity on mouse lung fibroblast cells(mLFC) was not served at all concentration of KSBH. KSBH in RAW264.7 cell inhibited IL-l${\beta}$, IL-6, TNF-${\alpha}$, COX-2 and NOS-II mRNA genes expression in a concentration-dependent manner, and specially inhibited NOS-II production very significantly at 100${\mu}$g/ ml. KSBH inhibited NO production significantly in a concentration-dependent manner and ROS production in a concentration-dependent manner. KSBH inhibited IL-l${\beta}$, IL-6 and TNF-${\alpha}$ production significantly in serum of acute anti-inflammation-induced mice. KSBH increased the survival rate from the 3rd day on LPS-induced lethal endotoxemia. Conclusion : These results suggest that Kagamsunbanghwalmyungeum(KSBH) can be useful in treating a lot of women mammary diseases caused by inflammation such as breast abscess.

The safety of a new natural plant composition (ADP) was assessed on the genotoxicity study and 14-day repeat dose toxicity study. ADP contains a mixed water extract obtained from the mixture of Phellodendron cortex (Phellodendron amurense) and Anemarrhena rhizoma (Anemarrhena asphodeloides), and poses the contractile properties mediated by alpha-adrenoceptor of the prostate and urethra as well as antioxidant and anti-inflammatory properties. In order to evaluate genetic safety, in vivo micronucleus test was performed in ICR mice orally administered with three dose levels of 1250, 2500, 5000 mg/kg body weight, and vehicle and positive control. In the 14 days study, Sprague-Dawley rats were treated with ADP at the dose levels of 500, 1000, 2000 mg/kg once a day, and clinical signs, body weights, hematology, serum biochemistry, necropsy findings and organ weights were monitored and examined. In experimental results, ADP treatment, compared with vehicle control, did not induce the micronucleated erythrocytes from mouse bone marrow. In the 14 days study, any significant and toxicological differences in all measurements of parameters were not observed in ADP treatment groups of animals, compared with vehicle treatment. The No-Observed-Adverse-Effect-Level (NOAEL) of ADP in the 14 days study was determined to be greater than 2000 mg/kg/day in both sexes.

The generation of secretory IgA antibodies (Abs) for specific immune protection of mucosal surfaces depends on stimulation of the mucosal immune system, but this is not effectively achieved by parenteral or even oral administration of most soluble antigens. Thus, to produce a possible vaccine antigen against urinary tract infections, the uropathogenic E. coli (UPEC) adhesin was genetically coupled to the heat-labile Escherichia coli enterotoxin A2B (ltxa2b) gene and cloned into a pMAL-p2E expression vector. The chimeric construction of pMALfimH/ltxa2b was then transformed into E. coli K-12 TB1 and its nucleotide sequence was verified. The chimeric protein was then purified by applying the affinity chromatography. The purified chimeric protein was confirmed by SDS-PAGE and westem blotting using antibodies to the maltose binding protein (MBP) or the heat labile E. coli subunit B (LTXB), plus the N-terminal amino acid sequence was analyzedd. The orderly-assembled chimeric protein was confirmed by a modified $G_{M1}$-ganglioside ELISA using antibodies to adhesin. The results indicate that the purified chimeric protein was an Adhesin/LTXA2B protein containing UPEC adhesin and the $G_{M1}$-ganglioside binding activity of LTXB. thisstudy also demonstrate that peroral administration of this chimeric immunogen in mice elicited high level of secretory IgA (sIgA) and serum IgG Abs to the UPEC adhesin. The results suggest that the genetically linked LTXA2B acts as a useful mucosal adjuvant, and that adhesin/LTXA2A chimeric protein might be a potential antigen for oral immunization against UPEC.

Objectives : We examined the effect of Jengjengamiyjin-tang, a traditional herbal formula, on the experimental pancreatitis induced by Dibutyltin Dichloride(DBTC). Methods : 15 mice were divided into 3 groups; the normal group and the control group which were administered water only after pancreatitis elicitation and the test group which were administered Jengjengamiyjin-tang for 7 days after pancreatitis elicitation. Results : In the activities of amylase, lipase and alkaline phosphatase in serum, the test group showed significant decrease compared with the control group after 21 days. In the common morphology and histochemical study, various injuries by hemorrhagic erosion were observed in the control group, while they were significantly decreased in the test group. In the immunohistochemical study, the manifestation of COX-1, 2, HSP27, HSP70, MAC387, Ki-67 decreased significantly in the 14th day in the test group, however, they increased in the 21st day more than the control group(p<0.05). Conclusion : According to the above results, it is supposed that Jengjengamiyjin-tang has anti-inflammatory effect on the experimentally induced pancreatitis and may be applicable to pancreatitis especially in the acute stage.

Effects of Mori Folium Ethanol Soluble Fraction (MFESF) on mRNA expression of glucose transporters, acetyl-CoA carboxylase (ACC) and leptin were examined in db/db mice. 500 and 1000mg/kg dose for MFESF (designated by SY 500 and SY 1000, respectively) and 5mg/kg dose for acarbose were administered for 6 weeks. Quantitations of glucose transporters (GLUT-2 and GLUT-4), ACC and leptin mRNA were performed by RT-PCR and in vitro transcription with co-amplification of rat ${\beta}$-actin gene as an internal standard. Muscular GLUT-4 mRNA expression in MFESF-treated groups were increased dose dependently. On the other hand, MFESF caused the GLLT-4 and leptin mRNA expressions in adipose tissue to decrease dose dependently, which means that triglyceride synthesis in adipocytes might be decreased and consequently signals adipocytes to inhibit the synthesis and release of leptin. Hepatic ACC mRNA expression in MFESF-treated groups was also decreased. and this may result in lowering of serum triiglyceride level. In contrast, liver GLUT-2 mRNA expressions in MFESF-treated and acarbose groups were increased. Higher rate of glucose uptake into hepatocytes is known to inhibit a phosphoenolpyruvate carboxykinase (PEPCK)-catalyzed reaction, which is a rate-limiting step in gluconeogenesis.

The present study was undertaken to investigate effects of ionizing radiation on DNA synthesis and chromosomal abnormality in cultured submandibular gland(SG) cells. SG cells from C57BL/6N Crj mice were cultured in Dulbecco's modified Eagle's medium (DME) supplemented with $10\%$ fetal bovine serum, antibiotics and fungizone. The cultured SG cells were irradiated with graded doses of gamma ray ($^{60}Co$) at a dose rate of 58.4rad/min. The effect of irradiation of $^{60}Co$ on DNA synthesis in cultured cells was evaluated by measuring the incorporation of 3H-TdR. Using conventional chromosome techniques and Giemsa staining methods, chromosomal abnormalities in cultured SG cells, induced by irradiation of $^{60}Co$ werw examined. Cytological observations were carried out by a light microscope with high resolving power. The results obtained were as follows : 1. DNA synthesis of SG cells was quantitatively dependent on a radiation dose compare to control. 2. A polyploids and few chromosome-type break, such as single and double breaks, deltions and triradial figures were more predominantly in irradiated SG cells than in control. This increase of chromosomal abnormality was in the proposition to the irradiation doses.
