Effect of Dietary Protein Levels on the Manifestation of Gramoxone Toxicity in Rat Liver
Kim, Sung-Ro ; Lee, Hyun-Ki ; Jo, Un-Bock ; Park, Byung-Tae ;
Journal of the Korean Society of Food Science and Nutrition, volume 21, issue 3, 1992, Pages 231~240
Effects of dietary protein levels on the manifestations of the toxicity of gramoxone, a bipyridine herbicide, in the liver of rats were investigated. The addition of gramoxone, with regard to the body weight and feed efficiency ratio of rats, had a move dramatic effect on animals fed a low or intermediate protein diet than for those similarly treated among rats fed a relatively high protein diet. Lipid content in the rat liver tended to increase with the addition of gramoxone into each protein diet, with the exception of the high protein-gramoxone diet. The addition of gramoxone tended to increase hepatic TBA value significantly in rats, especially among those fed the low protein-gramoxone diet or the control-gramoxone diet. Significant morphological changes, including fat changes of hepatic cells and increases in the number of Kupffer cells, were found both in rats fed the low protein diet and those fed any of the gramoxone-treated diets. fat changes within hepatic cells were found to be especially severe in rats fed the low protein-gramoxone diet. Distributions of glycogen in rat liver appeared to increase in rats fed any of the diets to which gramoxone had been added.

To clarify the requirement of L-ascorbic acid (AsA) in collagen synthesis, the incorporation of 1-
C-proline into the tissues of guinea pigs and the specific radioactivity ratio (proline/hydroxyproline) in collagen were investigated. Male guinea pigs maintained on the AsA-deficient diet were divided into three groups ; group A (AsA-deficient animals) : group B (control animals) supplemented with 5mg AsA/day ; group C (high dose animals) with 300mg AsA/day, and orally supplemented with or with-out AsA for 14 days. Collagen synthesis was estimated by measuring the incorporation of labeled pro-line into collagen in lung and dorsal skin, and the hydroxyproline contents in lung and skin. The AsA contents in the tissues were determined by high-peforrnance liquid chromatography (HPLC), and serum alkaline phosphatase activity was also measured. The serum alkaline phosphatase activity of AsA deficient group was very low as compared with those of AsA supplemented group. Incorporation of labelled proline into collagen and its specific radioactivity ratio in collagen increased with increasing levels of AsA in the tissues. There was a significantly positive relationship between the levels of AsA and hydroxyproline in the tissues.

Journal of the Korean Society of Food Science and Nutrition, volume 21, issue 3, 1992, Pages 247~254
In the experiment in which young chicks were fed the semisynthetic diet devoid of choline or the same diet with butanolamine supplementation, the weight gain was decreased significantly accompanied by the reduction of feed consumption in choline deficient chicks as compared to control chicks. However, the overall effects of choline deficiency on the relative liver weight, lipid contents of liver, and plasma lipid and lipoprotein levels were not observed, nor was the response to choline deficiency on the incorporation of
C-oleic acid into lipids in the liver microsomes. When hyperlipidemia was induced by estrogen treatment, the liver lipids, as well as relative liver weight, showed a tendency to be increased only in the chicks fed the semisynthetic diet devoid of choline with butanolamine supple-mentation. And the magnitude of elevation of VLDL lipids by estrogen treatment was the lowest in the above group. These results indicated that young chicks were not able to synthesize considerable choline for normal growth ; nevertheless, the release of VLDL by hepatocytes was performed normally. But it was also implied that there might be some problems of VLDL release under the condition of hyperlipidemia in chicks in choline deficiency accelerated by butanolamine supplementation.

In vitro digestibility of filefish, protein was substantially decreased by fiber constituents in the follow-ing order : pectin (9.97%), gum karaya (7.03%), sodium alginate (6.12%),and cellulose (1.52%). The order of reduction by fibrous residues from vegetables ranked as follows : sea tangle (12.36%), Ro-maine lettuce (11.12%), perillar leaf (8.96%), and green pepper (5.15%). The inhibitory effect of the dietary fibers towards filefish protein digestion, expressed as soybean trypsin inhibitor equivalents, in-creased with added levels, but the inhibition differed with the sources of dietary fibers. Sea tangle and sodium alginate were most active in decreasing the concentration of essential amino acid from filefish protein hydrolysis. Sodium alginate exerted an inhibitory effect on the activity of trypsin, but the other fiber constituents did not have an inhibitory potency on trypsin and bacterial pretense (Streptomyces griceus). Results supported that dietary fiber components may reduce protein digestibility through the interaction of dietary fiber components with filefish protein.

Radish green juice was used as a dual source for the production of plant protein precipitate and Candida utilis biomass. Precipitates ranging from 10.0 to 16.5g were obtained from a liter of radish green juice by heating at 80-10
C for 1 to 10 min or by modification of the pH of radish green juice. Crude protein content of the precipitate was between 25 and 38%. The residue remaining after protein precipitation was used in turn for the cultivation of the yeast, C. utilis, in order to produce yeast biomass. C. utilis grew well in radish green residual juice and completed growth within 24 hr at 3
and 200rpm in shake flask experiments. Maximum dry cell weight obtainable from a liter of radish green residual juice was 19.5g, when the yeast was grown on the juice residue diluted 3 times or more with water to make sugar content be equal to or less than about 1.0%. Supplementation of 3-fold diluted radish green residual juice with yeast extract and (NH
enhanced yeast biomass production and cell protein content significantly. Total high protein material obtainable from a liter of radish green juice was 33.0g.

Two of the Hard White Winter (HWW) wheats had higher farina yield than mixed Hard Red Winter (HRW) wheat. Optimum steaming time for HRW farina spaghetti was 3min under 86-98
. Optimum cooking time decreased after steam treatment. Steam treated spaghetti showed much higher strength of dried spaghetti, lower cooking loss, and cooked weight, less stickiness, and total organic matters (TOM) value than in treated spaghetti after cooking. The rooking qualities except stickiness were significantly different between treated and untreated steam. The quality of hard wheat farina spaghetti was more affected than that of durum spaghetti after steam treatment. HWW farina spaghetti im-roved all the qualities of steam treated and untreated spaghetti than those of HRW farina spaghetti except stickiness. From the observations of scanning electron microscope (SEM), maybe two general principles of steaming can be explained by : i) forming hydrophobic protein film on surface of pasta, ii) higher retrogradation of starch, which cause less swelling of starch.

Cytidine deaminase (EC 188.8.131.52) from Aspergillus fumigatus IFO 5840, which was the first cytidine deaminase to be found in a mold, was fractionated with ammonium sulfate (35-60%). When the enzyme solution in 0.25M of Tris-HCI buffer (pH 7.2) was preincubated at
for 25min, the enzyme activity was reached to maximum state. The optimum pH and temperature for the enzyme activity were found to be 6.8 to 7.2 and near
, respectively. The enzyme was stable in a pH 7.2 to 9.0, and was generally stable at 4
, but after treating at 6
for 20min at the optimal pH, 17% of the enzyme activity was inactivated, and disappeared completely by treating at 1
for 25min. Activation energy (Ea) of fungal cytidine deaminase was calculated as 14.190 Kcal /mol by the Arrhenius plot, and temperate coeffient (
) of the enzyme was calculated as 2.163.

Journal of the Korean Society of Food Science and Nutrition, volume 21, issue 3, 1992, Pages 286~290
From the leaves of Allium tuberosum (Liliaceae), . the purine nucleoside, adenosine was isolated and its structure was characterized on the basis of spectral data. Besides this nucleoside, the composition and relative content of free amino acids and related compounds, compared to standards determined under identical conditions was also investigated using automatic amino acid analyzer. Major free amino acids were alanine, glutamic acid, aspartic acid and valine.

The methanol extracts from different parts of Ixeris sonchifolia (Compositae) were evaluated for their total cholesterol lowering effect in mice. Mice were rendered hypercholesterolemic with 1% cholesterol and 0.5% cholic acid. Significant lowering in serum cholesterol was observed in mice with the methanol extract from leaves (MeOH-LF), whereas the methanol extract from roots (MeOH-RT) was devoid of this effect. In rats with cholesterol-induced hyperlipidemia MeOH-LF in a dose of 100mg/kg body weight caused significant decrease of total cholesterol, and the atherogenic index was also improved. On the other hand, total cholesterol in rats fed a stock diet was not affected by administration of the MeOH-LF. Thus, it is suggested that this MeOH-LF probably may increase the metabolic utilization only when fed with excess cholesterol.
The Pharmaco-chemical Study on the Plant not Ixeris spp. 2. Flavonoids and Free Amino Acid Composition of Ixeris sonchifolia
Young, Han-Suk ; Im, Kwang-Sik ; Park, Jae-Sue ;
Journal of the Korean Society of Food Science and Nutrition, volume 21, issue 3, 1992, Pages 296~301
From the leaves of Ixeris sonchifolia (Compositae), luteolin and its glucoside and apigenin glucuronide were isolated and their structures were characterized on the basis of spectral data. Besides these flavonoids, the composition and relative content of free amino, acids and related compounds, compared to standards determined under identical conditions was also investigated using automatic amino acid analyzer. Major free amino acids were glutamic acid, aspartic acid, serine, proline, valine and arginine.

Journal of the Korean Society of Food Science and Nutrition, volume 21, issue 3, 1992, Pages 302~307
The methanol extract of perilla leaves contained compounds to reduce the mutagenicity of aflatoxin B
) in Salmonella typhimurium TA98 and 100. They were separated by solvent extractions and identified by GC and GC-MS as 2-ethoxy acetate, 1, 2, 3, 4-tetramethyl-cis-cyclobutene, two isomers of methyl 11, 14, 17-eicosatrienoate, 12-acetyl-9-octadecanoic acid, and phytol. The antimutagenicities of phytol and methyl 11, 14, 17-eicosatrienoate were dependent on the mutagens tested. Phytol reduced the mutagenicity of Trp-p-2 but not of AFB
and methyl 11, 14, 17-eicosatrienoate reduced the activities both of the mutagens.

Journal of the Korean Society of Food Science and Nutrition, volume 21, issue 3, 1992, Pages 308~313
Volatile aromatic compounds collected from raw and roasted mugwort (Artemisia asictica nakai) leaves by the Tenax trap and some major volatile compounds were separated and identified by GC-MS. The identified compounds were tested for the antimutagenic and mutagenic activities against aflatoxin B
) using their authentic compounds. Six compounds (myrcene, cineole, camphor, caryophyllen, coumarin, and farnesol) showed antimutagenic activities, but 2-pyrrolidine and thujone showed mutagenic activities. 1-Acetylpiperidine formed during roasting mugwort leaves exhibited mutagenic activities. When the mutagens and antimutagens were mixed, the mixture reduced the mutagenicity of AFB
. These results suggested that the extract of mugwort leaves is not mutagenic and so the mugwort leaves might be used as a food and as medicinal sources without mutagenicity.

The sarcoma 180 cells were treated with ursolic acid which was previously extracted from leaves of Eriobotrya japonica Lindy (Rosaceae) and identified as a potent anticarinogenic agent. Suppressing effects of the compounds with testing changes in selected oncogenes expression were examined by using the northern hybridization method. Ursolic acid significantly suppressed c-myc oncogene expression. However, c-ha-ras oncogene expression was lowered slightly with the ursolic acid treatment. Therefore, it was concluded that preproven anticarcinogenic effects of ursolic acid should be partly ascribed to the modified oncogenic expression.

The Louisiana crawfish industry comprises the largest concentration of crustacean aquaculture in the United States. Processing plants throughout the culture region annually generate as much as 80 million pounds of peeling waste during recovery of the 15% (by weight) edible tail meat. A commercial oil extraction process for recovery of carotenoid astaxanthin from crawfish waste has been developed. Crawfish pigment in its various forms finds applications as a source of red intensifying agents for use in aquaculture and poultry industries. Crawfish shell, separated in the initial pigment extraction step, is an excellent source of chitin. Applicable physicochemical procedures for isolation of chitin from crawfish shell and its conversion to chitosan have been developed. Crawfish chitosan has been demonstrated to be both an effective coagulant and ligand-exchange column material , respectively, for recovery of valuable organic compounds from seafood processing wastewater.
