Effects of Ginseng Saponin on the Lysosomal Enzyme Activities in Streptozotocin-induced Diabetic Mice
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 105~109
Lysosomal enzymes might play a most important role in the pathogenesis od diabetic microangiopathy. Some glycosidases, which participate in the catabolism of glycoprotein, are significantly decreased in diabetic mice. In search of new potential lysosomal enzyme inducers, we examined the effects of crude red-ginseng saponin fraction on N-acetyl-
-D-mannosidase activities in the liver and kidney of normal and streptozotocin induced diabetic mice. It was found that i.p. administration of ginseng saponin produced the induction of lysosomal enzymes in the kidney more intensively than in the liver. The obtained results suggest the possibility that ginseng saponin might prevent the diabetic microangiopathy.
Acute Toxicity Study of Yan-Sheng Health Liquid in Rats and Mice
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 111~116
The acute toxicity of orally administered Yan-Sheng health liquid (YSHL), water extracts from twelve Chinese drugs (Cervi Cornu, Lonicerae Flos, Foeniculi Fructus, Glycyrrhizae Radix, Liriopis Tuber, Raphani Semen, Bombyx, Ginseng Radix alba, Cinnamomi loureirii Cortex, Epimedii Herba, Zingiberis Rhizoma, Lycii Fructus) was evaluated in male and female Sprague-Dawley rats and ICR mice. Rats and mice aging 5 weeks were gavaged with 0, 2.0, 3.0, 4.4, 6.7, 10.0, 66.7, or 100.0 ml/kg of YSHL. No animal died by oral treatment and no toxic symptom was observed in the treated animals during 5 days. The body weight of the treated animals was not significantly different from the controls. The results of macroscopic examination on the organs of the treated animals revealed no abnormal findings. Therefore, it was concluded that YSHL was practically non-toxic when it was orally administered to rats and mice, and its LD50 was suspected to be greater than 100 ml/kg in rats and mice.
Study on Characterizations of Campylobacter jejuni Isolated from Street Vended Foods
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 117~121
On the purpose of epidemiological survey related to foods poisoning, a total of 316 specimens collected from street vended foods in Pusan area were examined for the presence of Campylobacter Jejuni(C. jejuni) and also the isolation rates, biochemical properties and antibiotic susceptibility were investigated. Of the 316 specimens, 13 strain(4.1%) of Campylobacter jejuni were isolated. Isolation rate for each food was 37.5% in gizzard, 4.1% in Korean sausage and 3.9% in kimpop. Isolated C. jejuni were grouped as biotype I(84.6%), II(7.7%) and IV(7.7%). C. jejuni isolated from street vended foods were resistant to cephalothin(100%), penicillin(84.6%) and erythromycin(76.9%), but sensitive to gentamicin(92.3%), kanamycin(84.7%) and chloramphenicol(77.0%).
Competitive Enzyme-Linked Immunosorbent Assay for Detection of Gentamicin Residues in Edible Animal products
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 123~131
An enzyme-linked immunosorbent assay(ELISA) was developed for the detection of residual gentamicin(GM) in edible animal products. The immunogen(GM-KLH conjugate) and coating antigen(GM-BSA conjugate) were prepared by coupling GM sulfate to keyhole limpet hemocyanin(KLH) and bovine serum albumin(BSA) in the presence of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, respectively. Polyclonal antibody to GM was produced in rabbits(New Zealand White, female) by using the immunogen and the antibody titer was measured by indirect ELISA. A competitive ELISA was developed using GM-bovine serum albumin conjugate as a coating antigen, GM(as standards or sample), polyclonal antibody to GM, secondary antibody conjugated with horseradish peroxidase as an enzyme, and H2O2 and o-phenylenediamine dihydrochloride as a substrate and a chromophore, respectively. The detection limit of GM was 10 ng/ml and the standard curve of GM(n=26) was linear up to 10
/ml in this competitive ELISA system. There were no cross-reactivities of the partially purified antibody between GM and the various antibiotice such as amikacin, benzyl-penicillin, chloramphenicol, erythromycin, furazlidone, kanamycin, neomycin, oleandomycin, streptomycin, sulfathiazole and thiamphenicol(CR50<0.05%)
Pyrolytic Formation of Benzo[a]pyrene in Foods During Heating and Cancer Risk Assessment in Koreans
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 133~139
The pyrolytic formation of benzo[a]pyrene during the cooking procedure was analysed in beef, pork, pacific saury, rice, and soybean by HPLC. In raw foods, benzo[a]pyrene (B[a]P) was not detected or negligible, but it was increasingly formed when foods were boiled (0.010~0.037 ppb) and more dramatically during broiling (0.302~0.851 ppb) in a time dependent manner. Human daily intake of B[a]P in Koreans and cancer risk assessment were estimated based on food consumption per capita and carcinogenic potency of B[a]P. When cooked foods were consumed for entire life time, cancer risk was estimated to bo 1.77
10-8 by the order of broiled, boiled, and raw foods consumption. These data suggest that broiled foods produce more benzo[a]pyrene than water boiled foods. Thus cooking procedure is an important factor for the formation of carcinogens and needs to bo modified to reduce cancer risk for man.
Antimicrobial Effect of Grapefruit Seed Extract on Vibrio parahaemolyticus Isolated from the Southern Adjacent Sea of Korea
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 141~149
To investigate the distribution of Vibrio parahaemopyticus in the southern 4 coastal areas, Vibrio parahaemolyticus was isolated from seawater, shellfish and sediment from May to October in 1991, and antimicrobial effect of grapefruit seed extract (GFSE) on the growth of isolated strains were examined. In the 120 sample from 4 coastal areas, 16 strains of Vibrio parahaemolyticus were isolated and identified. The distribution serotype of isolated strains was 10 types of monovalent k-antiserum. Especially k-5 and k-28 were highly distribyted with 3 and 4 strains. 31.3% of isolated strains showed positive on Kanagawa phenomenon test. All isolated Vibrio parahaemolyticus were sensitive to chloramphenicol and gentamycin, 5 and 6 strains were resistant to streptomycin and colistin, respectively. Isolated strains were compared with geographical, month and sample. The distribution of 16 isolated Vibrio parahamolyticus was high at Hadong with 50%(8 strains), on July with 43.8%(7 strains) and from seawater with 37.5%(6 strains) respectively. Minimal inhibitory level of GFSE to Vibrio parahaemolyticus was 50 ppm. With 100 ppm treatment of GFSE, the destroy of cell membrane function, outflow of cell ingredients and ghost morphology of cell were investigated.
Application of Gamma Irradiation for Quality Improvement of Red Ginseng
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 151~161
Gamma irradiation was applied to red ginseng for improving its quality. Irradiation at 5~7 kGy was effective for sterilizing all contaminated microorganisms of red ginseng. At the dose levels, no significant shanges in physicochemical properties (color, saponin, lipid rancidity and fatty acids etc.) were observed even after 6 months storage. Gamma irradiation was also effective for the improving hygienic quality of packed red ginseng with high moisture content (up to 20%), without any quality deterioration.
Effect of Capsaicin and Its Novel Derivative on the Isolated Guinea Pig Bronchi
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 163~168
In the present study we investigated the peripheral function of capsaicin and KR-25018, a newly synthesized capsaicin derivative, which was demonstrated to have a potent analgesic activity through different mechanism from morphine and nonsteroidal antiinflammatory drugs. Capsaicin (10-8~10-5 M) and KR-25018 (10-8~10-5 M) produced concentration-dependent contractions of the isolated guinea pig bronchi. There were no significant differences in the maximum response and the EC50 values (EC50: 0.137
M and 0.097
M for capsaicin and KR-25018, respectively, P>0.05). Phosphoramidon (10
M) and indomethacin (10
M) had no significant effect on contractile response to the submaximal concentration range of capsaicin and KR-25018 (3
10-7 M). The response to KR-25018, like that to capsaicin, was significantly inhibited by ruthenium red with reduction in the maximum response, which is indicative of non-competitive antagonism. A further common feature of the responses to capsaicin and KR-25018 in the guinea pig bronchi was their sensitivity to capsazepine. Capsazepine caused a rightward parallel shift in concentration-response curves obtained by capsaicin and KR-25018. the pA2 values of capsazepine were 5.90 and 5.99 against capsaicin and KR-25018 response, respectively. In conclusion, KR-25018 and capsaicin exert their contractile effects in the isolated guinea pig bronchial muscle by common mechanisms, probably via the activation of a specific receptor.
Inhibitory Effect of Bovine Milk on the Progression of Atherosclerosis in Rats
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 169~174
This stydy was performed to investigate the inhibitory effect of bovine milk on the atherosclerotic rats. Eighty male rats of 5-weeks of age were divided into 4 groups, control, active treatment control fed the atherogenic feed, and skim milk and whole milk groups fed powdered skim or whole milk mixed with the atherogenic feed and observed for 13 weeks. Growth, clinical and pathological changes of the rats were examined. Rats of the 4 groups did not show significant difference of feed intake and weight gain. The level of serum cholesterol, high density lipoprotein cholesterol (HDL-cholesterol) fraction, and inorganics between skim milk and whole milk groups were not significantly different though significant difference was shown between active treatment control and milk groups. Milder calcification and nearosis in aorta, heart and kidney and fat degeneration in liver were seen in the milk groups than were in active treatment control. Marked difference, however, was not found between the skim milk and whole milk groups. Both powdered skim and whole milks could have a helpful effect of vitamin D2-and -cholesterol-induced atherosclerosis in rats.
The Antiulcer Effects of Alove vera on the Stomach ulcer Induced by Stress in rats
Journal of Food Hygiene and Safety, volume 9, issue 3, 1994, Pages 175~184
This was performed to investigate the antiulcer effects of Aloe vera on the stomach ulcer induced by restraint and water-immersion stress in rats. For this experiment, 60 male Sprague-Dawley strain were used. The experimental groups were divided into five: a control(CA) and 4 aloe treatment groups. Each dose of aloe was 50 mg/kg BW(AA), 100mg/kg BW(AB), 200 mg/kg BW(AC), and 400 mg/kg BW(AD). The rats were allocated to each group by 12 and observed for 4 weeks. The results are as following. 1. The stomach surface pH in each group showed no significant difference, byt the values of aloe treatment groups were higher than the value of the control group. 2. The gastric wall mucus was significantly increased in all aloe treatment groups(p<0.05) compared with the control group. Especially in AC and AD group the differences were higher(p<0.01). 3. At shear rate rate 11.25, 45.0, 90.0, 225.0 sec-1, whole blood viscosity and plasma viscosity were measured. Most of the values of aloe treatment groups were significantly low compared with those of the control group(P<0.05). 4. The ulcer index of aloe treatment groups were significantly low campared with control group(p<0.05). Especially in AC and AD group the differences were more significant(p<0.01). 5. Less severe ulcers were observed in AA and AB group than in the control group. Tissues of AC and AD group had only slight ulcers and necrosis of tissue was not observed in these groups. Especially in AD group, there was more mucus than other groups and it seemed that alove vera stimulated the epithelial regeneration. From the results of this study, it can be concluded that the oral administration of Alove vera results in protection of stomach ulcer by stimulating the secretion of gastric mucus and the circulation of blood.
