This paper introduces the physicochemical characteristics of garlic shoots investigated in the 8 areas of Namhae, Gohyeon-myeon (GHM), Nam-myeon (NM), Samdong-myeon (SDM), Namhae-eup (NHE), Seo-myeon (SM), Seolcheon-myeon (SCM), Idong-myeon (IDM) and Changsoen-myeon (CSM). The moisture was $80.15{\pm}0.37{\sim}83.87{\pm}0.15g/100g$. The crude protein and lipid were $1.59{\pm}0.02{\sim}2.25{\pm}0.09g/100g$ and $0.35{\pm}0.01{\sim}0.48{\pm}0.03g/100g$, respectively. Ash was $0.65{\pm}0.03{\sim}0.71{\pm}0.03g/100g$. In addition, the total levels of phenol and flavonoid were searched as $33.02{\pm}1.78{\sim}58.41{\pm}1.08mg/100g$ and $11.60{\pm}3.36{\sim}23.95{\pm}2.04mg/100g$, respectively. The garlic shoots in IDM, where the highest total chlorophyll level detected as $170.58{\pm}1.04{\mu}g/g$ and in CSM, where the lowest total chlorophyll level investigated as $116.65{\pm}0.00{\mu}g/g$, were unveiled. The mineral elements (S, Ca, Fe, K, Mg, Na, Mn and Zn) were analyzed by ICP-OES, and K was the most highly contained mineral with $7257.0{\pm}87.9{\sim}10070.0{\pm}9.7mg/kg$. Significant feature of garlic shoots in IDM and NHE was that the total amounts of mineral were relatively higher than other regions as 21,143.5 mg/kg and 20,581.2 mg/kg, respectively. The cultivating regions were revealed as the one of important matters with the level of allicin ($78.03{\pm}6.15{\sim}203.43{\pm}18.47mg/kg$). In particular, the level of allicin of garlic raised in SDM ($203.43{\pm}18.47mg/kg$) was approximately 2.2~2.6 times higher than those in CSM ($92.86{\pm}8.70mg/kg$) and SCM ($78.03{\pm}6.15mg/kg$). The sulfur compounds content of diallyl trisulde was remarkably higher, especially the garlic shoots in IDM with $830.62{\pm}14.69{\sim}1281.10{\pm}27.71mg/kg$.
The studies were carried out to disclose the physical and chemical properties of sericin fraction obtained from silk cocoon shells and its characteristics of swelling and solubility. The following results were obtained. 1. The physical and chemical properties of sericin fraction. 1) In contrast to the easy water soluble sericin, the hard soluble sericin contains fewer amino acids include of polar side radical while the hard soluble amino acid sach as alanine and leucine were detected. 2) The easy soluble amino acids were found mainly on the outer part of the fibroin, but the hard soluble amino acids were located in the near parts to the fibroin. 3) The swelling and solubility of the sericin could be hardly assayed by the analysis of the amino acid composition, and could be considered to tee closely related to the compound of the sericin crystal and secondary structure. 4) The X-ray patterns of the cocoon filament were ring shape, but they disappeared by the degumming treatment. 5) The sericin of tussah silkworm (A. pernyi), showed stronger circular patterns in the meridian than the regular silkworm (Bombyx mori). 6) There was no pattern difference between Fraction A and B. 7) X-ray diffraction patterns of the Sericin 1, ll and 111 were similar except interference of 8.85A (side chain spacing). 8) The amino acids above 150 in molecular weight such as Cys. Tyr. Phe. His. and Arg. were not found quantitatively by the 60 minutes-hydrolysis (6N-HCI). 9) The X-ray Pattern of 4.6A had a tendency to disappear with hot-water, ether, and alcohol treatment. 10) The partial hydrolysis of sericin showed a cirucular interference (2A) on the meridian. 11) The sericin pellet after hydrolysis was considered to be peptides composed with specific amino acids. 12) The decomposing temperature of Sericin 111 was higher than that of Sericin I and II. 13) Thermogram of the inner portioned sericin of the cocoon shell had double endothermic peaks at 165$^{\circ}C$, and 245$^{\circ}C$, and its decomposing temperature was higher than that of other portioned sericin. 14) The infrared spectroscopic properties among sericin I, II, III and sericin extracted from each layer portion of the cocoon shell were similar. II. The characteristics of seriein swelling and solubility related with silk processing. 1) Fifteen minutes was required to dehydrate the free moisture of cocoon shells with centrifugal force controlled at 13${\times}$10$^4$ dyne/g at 3,000 R.P.M. B) It took 30 minutes for the sericin to show positive reaction with the Folin-Ciocaltue reagent at room temperature. 3) The measurable wave length of the visible radiation was 500-750m${\mu}$, and the highest absorbance was observed at the wave length of 650m${\mu}$. 4) The colorimetric analysis should be conducted at 650mu for low concentration (10$\mu\textrm{g}$/$m\ell$), and at 500m${\mu}$ for the higher concentration to obtain an exact analysis. 5) The absorbing curves of sericin and egg albumin at different wave lengths were similar, but the absorbance of the former was slightly higher than that of the latter. 6) The quantity of the sericin measured by the colorimetric analysis, turned out to be less than by the Kjeldahl method. 7) Both temperature and duration in the cocoon cooking process has much effect on the swelling and solubility of the cocoon shells, but the temperature was more influential than the duration of the treatment. 8) The factorial relation between the temperature and the duration of treatment of the cocoon cooking to check for siricin swelling and solubility showed that the treatment duration should be gradually increased to reach optimum swelling and solubility of sericin with low temperature(70$^{\circ}C$) . High temperature, however, showed more sharp increase. 9) The more increased temperature in the drying of fresh cocoons, the less the sericin swelling and solubility were obtained. 10) In a specific cooking duration, the heavier the cocoon shell is, the less the swelling and solubility were obtained. 11) It was considered that there are differences in swelling or solubility between the filaments of each cocoon layer. 12) Sericin swelling or solubility in the cocoon filament was decreased by the wax extraction.. 13) The ionic surface active agent accelerated the swelling and solubility of the sericin at the range of pH 6-7. 14) In the same conditions as above, the cation agent was absorbed into the sericin. 15) In case of the increase of Ca ang Mg in the reeling water, its pH value drifted toward the acidity. 16) A buffering action was observed between the sericin and the water hardness constituents in the reeling water. 17) The effect of calcium on the swelling and solubility of the sericin was more moderate than that of magnecium. 18) The solute of the water hardness constituents increased the electric conductivity in the reeling water.

The formation of astaxanthin by Xanthophyllomyces dendrorhous mutant JH1 depends on the culture conditions. Therefore, the effects of inoculation rate (1-5%, v/v) and medium compositions (various carbon and nitrogen sources) on cell growth and astaxanthin formation in X. dendrorhous mutant JH1 were investigated. Inoculation at 3% (v/v) was optimal for cell growth and astaxanthin formation. The most effective carbon source for cell growth and astaxanthin formation was glucose, and the best nitrogen source was yeast extract. The 3% (w/v) glucose and 0.2% (w/v) yeast extract showed the best effect on cell growth and astaxanthin formation, compared with others tested. The 3% glucose, 0.2% yeast extract, $0.15%\;KH_{2}PO_{4}$, $0.05%\;MgSO_4$, $0.01%\;MnSO_4$, and $0.01%\;CaCl_2$ were selected for cell growth and astaxanthin formation. Under the conditions selected, the maximum concentrations of cell and astaxanthin obtained after 168 h of cultivation were 5.43 g/l and 28.20 mg/l, respectively.

Two feeding trials were conducted to evaluate the effects of inclusion levels of dietary vitamin and trace mineral (VTM) premixes on growth and nutrient digestibility in growing pigs. A total of 112 pigs ($24.82{\pm}3.22kg$) were employed for 49 days (exp. 1), and 168 pigs ($21.64{\pm}1.41kg$) for 40 days (exp. 2) in completely randomized block designs. Treatments were: 1) 100%, 2) 150%, 3) 200% and 4) 250% NRC (1998) requirement of VTM in exp. 1, and the ratio of vitamins to trace minerals at 1) 100:100%, 2) 100:150%, 3) 150:100% and 4) 150:150% of NRC (1998) requirement in exp. 2. Basal diets for feeding trials were formulated to contain 3,310 kcal ME/kg and 18% crude protein, and contained 0.25% chromic oxide as an indigestible marker for digestibility trials. Increasing dietary VTM premix in growing pigs had linear and quadratic effects (p<0.05) on ADG, and feed conversion ratio was also improved (p<0.05) as VTM premix was increased by 150-250% of NRC (1998) requirements in exp. 1. Adding vitamin to trace mineral premixes at 150% NRC (1998) over the control improved (p<0.05) ADG and feed efficiency in growing pigs, but performances were not improved by vitamin nor by trace mineral premixes alone (p>0.15) (exp. 2). There were no differences (p>0.05) in the digestibilities of energy, crude protein and fat among dietary treatments. However, increasing dietary VTM premix in growing pigs had a linear effect (p<0.05) on the digestibilities of calcium and phosphorus. The 200 or 250% fed group showed improved (p<0.05) calcium digestibility, and 250% fed group also showed improved (p<0.05) phosphorus digestibility as compared to 100% or 150% fed group (exp. 1). The digestibilities of Ca and P were higher (p<0.05) in 150% addition of vitamins than in 150% addition of trace minerals in the diet (exp. 2).
Although each part of Trichosanthes kirilowii is frequently used as medicinal herbs, study on the chemical composition is not sufficient. It was found that sarcocarp consists of 70% of carbohydrate, 13% of crude protein, 5% of crude fat, 6% of crude fiber and 6% of crude ash; seed consists of 62.59% of carbohydrate, 12.75% of crude protein, 14.80% of crude fat, 6.50% of crude fiber and 3.36% of crude ash; and root consists of 89.40% of carbohydrate, 4.10% of crude protein, 0.50% of crude fat, 3.50% of crude fiber and 2.50% of crude ash. Sarcocarp and seed contain fifteen kinds of amino acids such as Asp, Ser, Glu, Gly, His, Arg, Thr, Ala, Pro, Try, Cys, Met, Val, Leu, and Phe. Sarcocarp contain large quantities of phenylalanine and glycine and seed does not contain leucine but lysine. The mineral contents in Trichoxanthes kirilowii are 0.55% Ca, 0.91% Mg, 10.29% Na, and 0.17% K.

Crude fucoidan was extracted from the sporophyll of Korean Undaria pinnatifida collected at a coastal area ofWando, Korea, mainly by dilute acid extraction, ethanol precipitation, CaCU Precipitation, with an yield of approxi-mately 3.9% in mass. It was further purified by DEAE-cellulose column chromatography and its chemical composi-don and in vitro anticoagulant activity was determined. The average molecular mass of the purified fucoidan wasestimated about 2.1 x 103 kDa by size-fractionation HPLC and it consisted of neutral sugar (52.34% in mass), uronicacid (26.2%), and sulfate esters (7.4%). From the HPAEC-PAD analysis, the monosaccharide composition of thepurified fucoidan was shown to be fucose, galactose, xylose, and mannose, with a molar ratio of 1, 0.2, 0.02, 0.15,respectively, demonstrating that major monosacd-iande was fucose (72.3% in mol percentage) and other sugars,xylose (1.5%), galactose (14.6%), and mannose (10.9%) were present as minor component. The results suggested thatthis fucoidan is a sulfated, U-type fucoidan. The activated partial thrombloplastin time (APTT) assay of the purifiedfucoidan showed that the purified fucoidan elicited anticoagulant activity in a dose-dependent manner. Five jUg ofsporophyll fucoidan delayed the blood clotting time up to 5 times than untreated control and also up to 1.5 timesthan the same amount of the commercial fucoidan, respectively. Although it is preliminary, these results suggestthat the fucoidan of Korean Undaria vinnatifida sporophyll would be promising candidates for the development ofan anticoaeulant.
In order to demonstrate whether ovoperoxidase hardens the zona of oocytes activated by incubating in M-S buffer supplemented with 20$\mu$M of Ca-ionophore A 23187, the effect of peroxidase inhibitors(250mM pheylhydrazine, 28mM sodilum sulfite, 350mM glycine ethyl ester and 50mM sodium azide), tyrosine analogue(12.5mM tyramine) and exogeneous peroxidase(50$\mu\textrm{g}$/ml horseradishperoxidase ; HRP) on zona hardening in ionorphore-treated oocytes were investigated. The results obtained from thses experiments were summarized as follows : 1. The zona solubility (t50) of ionophore-activated and DMSO-treated oocytes at 1, 2 and 3 hr of culture were 25.0, 31.6 and 40.6min., and 9.7, 10.8 and 15.5 min., respectively. The longest time required for zona lysis of ionophore activated oocytes at 1 hr after onset of ionophore treatment. The diferences int50 for zona was significantly greater as compared to DMSO-treated controls(P<0.01). 2. The inhibition rates of hardening in the oocytes treated with the phenylhydrazine, sodium sulfite, glycine ethyl ester and sodium azide, were 23.8, 61.9, 95.2 and 23.8%l, respectively, and the tyramine, was 14.3%. Several known peroxidase inhibitors and tyrosine analogue were blocked zona hardening in ionophore activated oocytes. 3. The treatment of exogeneous peroxidase promoted the zona hardening of activated oocytes but not unactivated oocytes. These resuls indicate that the ovoperoxidase apparently catalyzes the hardening of the zona following ionophore activation of mouse oocytes.
The effects of adenosine analogues on the electrically-evoked norepinephrine(NE) release and the influence of ischemia on the effects were studied in the rat hippocampus. Slices from the rat hippocampus were equilibrated with $0.1{\mu}M$$[^3H]-norepinephrine$ and the release of the labelled product, $[^3H]-NE$, was evoked by electrical stimulation(3 Hz, 2 ms, 5 $VCm^{-1}$ and rectangular pulses for 90 sec), and the influence of various agents on the evoked tritium-outflow was investigated. Ischemia(15min with 95% $N_2$ +5% $CO_2$) increased both the basal and evoked NE release. These increases were abolished by addition of glucose into the superfused medium, and they were significantly inhibited either by $0.3\;{\mu}M$ tetrodotoxin pretreatment or by removing $Ca^{++}$ in the medium. MK-801$(1{sim}10\;{\mu}M)$, a specific NMDA receptor antagonist, and glibenclamide $(1\;{\mu}M)$, a $K^+-channel$ inhibitor, neither alter the evoked NE release nor affected the Ischemia-Induced increases in NE release. However, polymyxin B(0.03 mg), a specific protein kinase C inhibitor, inhibited the effect of ischemia on the evoked NE release. Adenosine and $N^6-cyclopentyladenosine$ decreased the NE release in a dose-dependent manner in ischemic condition, though the magnitude of inhibition was far less than those in normal (normoxic) condition. Also the treatment with $5{\mu}M$ DPCPX, a potent $A_1-adenosine$ receptor antagonist did not affect the ischemia-effect. These results suggest that the evoked-NE release is potentiated by ischemia, and this process being most probably mediated by protein kinase C, and that the decrease of NE release mediated through $A_1-adenosine$ receptor is significantly inhibited in ischemic state.
The crystal structure of dehydrated $Rb^+$-exchanged zeolite X, stoichiometry $Rb_{71}Na_{21}-X\; (Rb_{71}Na_{21}Si_{100}Al_{92}O_{384})$ per unit cell, has been determined from single-crystal X-ray diffraction date gathered by counter methods. The structure was solved and refined in the cubic space group Fd3, a=25.007(3) Å at 21(1) ℃. The crystal was prepared by ion exchange in a flowing stream using a 0.05 M aqueous RbOH solution (pH=12.7). The crystal was then dehydrated at 360 ℃ and $2{\times}10^{-6}$ torr for two days. The structure was refined to the final error indices, $R_1=0.047$ and $R_2=0.040$ with 239 reflections for which I> 3σ(I). In this structure, 71 $Rb^+$ ions per unit cell are found at six different crystallographic sites and 21 $Na^+$ ions per unit cell are found at two different crystallographic sites. Four and a half $Rb^+$ ions are located at site Ⅰ, the center of the hexagonal prism. Nine $Rb^+$ ions are found at site Ⅰ' in the sodalite cavity (Rb-O=2.910(15) Å and O-Rb-O=78.1(4)°). Eighteen $Rb^+$ ions are found at site Ⅱ in the supercage (Rb-O=2.789(9) Å and O-Rb-O=92.1(4)°). Two and a half $Rb^+$ ions, which lie at site Ⅱ', are recessed ca. 2.07 Å into the sodalite cavity from their three O(2) oxygen planes (Rb-O=3.105(37) Å and O-Rb-O=80.6(5)°). Thirty-two $Rb^+$ ions are found at site Ⅲ deep in the supercage (Rb-O=2.918(12) Å and O-Rb-O=71.9(4)°), and five $Rb^+$ ions are found at site Ⅲ'. Seven $Na^+$ ions also lie at site Ⅰ. Fourteen $Na^+$ ions are found at site Ⅱ in the supercage (Na-O=2.350(19) Å and O-Na-O=117.5(6)°).
