  • The quality characteristics of seasoned pork with sauces containing different concentrations of fermented Oenothera biennis juice such as 5% (5-SP), 10% (10-SP) and 15% (15-SP) during storage for 15 days at $10^{\circ}C$ were investigated. The pH level decreased after storage for 6 days and pH 4.83~4.90 after storage for 15 days in all tested seasoned pork. The titratable acidity increased significantly after 6 days but did not show significant differences between seasoned pork. The total bacteria of seasoned pork were $10^7CFU/g$ (control) and $10^6CFU/g$ (5-SP and 10-SP) after storage for 9 days. The total bacteria showed a lower 1~2 log cycle in seasoned pork with fermented Oenothera biennis juice compared to control. The volatile basic nitrogen contents of seasoned pork were 18.02 mg% (control), 15.41 mg% (5-SP), 14.47 mg% (10-SP), and 17.51 mg% (15-SP) after storage for 15 days at $10^{\circ}C$, respectively. The a value (red) of pork seasoned with fermented Oenothera biennis juice was higher than that of control and decreased during storage. Cooking loss and water holding capacity of 5-SP and 10-SP were better than those of control and 15-SP during storage. The 5-SP showed the best sensory score in taste (4.00), color (4.00), flavor (3.91), and overall acceptability (4.09) among various seasoned pork groups.

  • The mechanism of the contractile response of longitudial muscle of rabbit ileum to substance P (SP) has been investigated. The contractions in rabbit ileum under various conditions were recorded isometrically The following results were obtained. 1) The contractions by SP increased according to concentrations. SP·induced contraction was not sustained but faded rapidly at $10^{-7}M$. The response to the commutative addition of SP was decreased in comparison to the response to separate administration of each concentration . 2) The response to $10^{-8}M$ SP after 5 min application cf $10^{-7}M$ SP was increased with increasing the time interval between the administration of $10^{-7}$ and $10^{-8}M$ SP. 3) The treatment of rabbit ileum by $10^{-7}M$ SP for 5 min didn't decrease the response to $10^{-6}M$ acetylcholine. 4) $10^{-6}M$ atropine had no effect of the contractile response to $10^{-7}M$ SP. The response to $10^{-7}M$ SP was normal or subnormal in the presence of 3 mM tetraethylammonium(TEA). 5) 100k solution, $10^{-4}M$ ouabain, and Na-free solution inhibited the response to $10^{-8}M$ SP and 3 mM TEA completely, and to $10^{-7}M$ SP incompletely. 3 mM TEA induced a considerable contraction in K-free solution, but $10^{-8}M$ SP didn't induce the contraction. $10^{-6}M$ norepinephrine decreased the contractile responses to SP and TEA. 6) The contractile response to $10^{-7}M$ SP was dependent on the extracellular $Ca^{2+}$ concentrations to 1.8 mM. 7) The contractile response to $10^{-7}M$ SP remained 15% of the maximal response after bathing the ileum in a Ca-free solution for 2.5 min. 8) The responsiveness to SP was completely lost within 10 min of bathing in Ca-free solution, but was restored by the exposure to $Ca^{2+}$. The restorative effect of $Ca^{2+}$ depended on the concentration of $Ca^{2+}$, and on time for which the tissue exposed to this $Ca^{2+}$ concentration. These results suggest that there are two mechanisms of the action by which the low concentrations of substance P causes the contraction of intestinal smooth muscle: the reduction of K conductance and a mechanism dependent on the extracellular $Ca^{2+}$, and that high concentration of SP may elicit a contraction by releasing $Ca^{2+}$ from an intracellular store, which is not as sensitive to removal of extracellular $Ca^{2+}$ or as easily accessible to EGTA as the extracellular space of the muscle. The location of this store is not known; it may be associated with the internal side of the cell membrane.

  • The crystal structures of two alditol acetates, D-glucitol hexaacetate and xylitol pentaacetate, have been determined by diffraction methods with Mo-K$\alpha$radiation, using direct methods for phase determinations. The crystal data are: for D-glucitol hexaacetate, P2$_1$, with a = 10.275 (2), b = 8.363 (1), c = 12.560 (5) $\AA;\beta$ = 95.97 $(2)^{\circ}$, Z = 2; for xylitol pentaacetate, P2$_1$/C with a = 18.126 (1), b = 11.422 (2), c = 8.649 (1) $\AA$, $\beta = 95.03 (1)^{\circ}$, Z = 4. Both molecules have extended zigzag carbon chain conformations which differ from previous studies of the structures of D-glucitol and xylitol and also differ from NMR studies on alditol acetates. The bond lengths and angles are normal, with mean values over both structures of C($sp^3)-C(sp^3): 1.514 (10),\; C(sp^3)-O: 1.444 (6),\; C(sp^2)-O: 1.347 (9),\; C(sp^2)=O: 1.197 (6),\; C(sp^2)-C(sp^3): 1.479(9){\AA},\; C(sp^3)-C(sp^3)-C(sp^3): 114.6 (17),\; O-C(sp^3)-C(sp^3): 109.4 (23),\; C(sp^2)-O-C(sp^3): 117.4 (6),\; O=C(sp^2)-O: 122.6 (6),\; C(sp^3)-C(sp^2)-O: 111.8 (7),\; C(sp^3)-C(sp^2)=O: 125.5 (4)^{\circ}$. The atoms of acetate groups are in coplanar. There are no particularly short intermolecular contacts and the molecules are held together by van der Waals force only.

  • The pathogenic organisms occurred in cultured marine fishes in Kamak Bay were investigated from March to November in 1993. The samples were collected at 7 sampling stations once a month. Nine species of pathogenic organisms (Vibrio sp., Edwardsiella sp., Flexibacter sp., Streptococcus sp., Micrococcus sp., Caligus sp., Trichodina sp., Lymphocystis and Staphylococcus sp.) were identified as pathogenic organisms from four different species of fish (Sebastes schlegeli, Paralichthys olivaceus, lateolabrax japonicus and Pagrus major) collected in the study areas. Most of pathogenic organisms were found at over 20^{\circ}C$ of sea water temperature from June to October in 1993. On the test of drug sensitivity, Vibrio sp. (KS-9303) was sensitive to oxytetracycline and chloramphenicol ; Edwardsiella sp. (KP-9315) to oxytetracycline ; Flexibacter sp. (KP-9318) to oxytetracycline, chloramphenicol and oxolinic acid ; Streptococcus sp. (KP-9319) to erythromycin, chlorampheicol and oxytetracycline. However, all these 4 isolated bacteria were resistant to ampicilin, steptomycin, sulfamethoxazole and nitrofurazone.

  • The qualities of Deodeok Doenjang including physicochemical characteristics and sensory properties were investigated over the following range of Deodeok levels: 5, 10, 15 and 20% (all w/w). The strains used in the manufacturing of Doenjang were Bacillus sp. B-3 and Aspergillus sp. M-9 with the highest enzyme activities like amylase and protease. In case of Deodeok Doenjangs prepared with Bacillus sp. B-3, the amino-type nitrogen of Doenjang containing 10% (w/w) Deodeok was produced more than others during fermentation for 40 days. Amino-type nitrogen produced in Deodeok Doenjang prepared with Aspergillus sp. M-9 was more than one of Deodeok Doenjangs with Bacillus sp. B-3 and a commercial Doenjang. When Deodeok content exceeded 15% (w/w), higher content resulted in lesser amino-type nitrogen production. The results showed that Deodeok had influenced growth of Bacillus sp. and Aspergillus sp. Sensory evaluation showed that Deodeok Doenjangs containing 10% (w/w) Deodeok and 1% (w/w) Bacillus sp. B-3 and containing 20% (w/w) Deodeok and 1% (w/w) Aspergillus sp. M-9 were superior to the other Doenjangs tested.
