  • The abilities of instant gruel manufactured with colored barley and oats to improve diabetic conditions were investigated using diabetes-induced mice and rats. Mice or rats were divided into a diabetic control group and one experimental group (seven animals per group). The control groups were fed without instant gruel and experimental groups were fed basal diets supplemented with 10% instant gruel for 8 weeks. The streptozotocin (STZ)-induced diabetic rats experimental group showed a significant decrease in food intake compared to the control group. Both Type II diabetic mice and STZ-induced diabetic rats experimental groups showed higher increases in body weight than the control groups. The blood glucose levels of the experimental groups ($352{\pm}12.2$ mg/dL in Type II diabetic mice; $296.4{\pm}13.2$ mg/dL in STZ-induced diabetic rats) were lower than the untreated control groups ($426.0{\pm}15.4$ mg/dL in Type II diabetic mice; $514.0{\pm}17.6$ mg/dL in STZ-induced diabetic rats). The serum insulin levels of Type II diabetic mice increased by 38.3% in the experimental group ($12.8{\pm}1.1$ ng/mL) compared to the control group ($7.9{\pm}0.5$ ng/mL). The immunohistochemical density of insulin-secreting cells and glucagon-like peptide-1 (GLP-1)-secreting cells in the pancreas were significantly higher in the experimental groups than the control groups for Type II diabetic mice and STZ-induced diabetic rats. Therefore, we conclude that instant gruel manufactured with colored barley and oats stimulates the secretion of insulin and decreases blood sugar by activating insulin-secreting cells in the pancreatic islets of diabetic animals.

  • Two experiments were conducted to study the nature of protein degradation in fish muscle postmortem, first one with English sole (Paraphyrus vetulus) followed by another with rockfish (Sebastodes spp.). In the first one, proteolysis was measured by the increase of amino-N in gutted fish during storage in ice and in the homogenates prepared from fish of different ice storage during $20^{\circ}C-incubation$. In order to test the possible involvement of fish muscle a cathepsin, a portion of each homogenate sample was exposed to 0.5 Mrad of gamma radiation to destroy viable microorganisms prior to the incubation. Proteolysis was not detected until viable count reached a level above $10^7$ cells per gm fish flesh, corresponding to 31 days of ice storage. Even if fish flesh were mechanically disrupted by means of homogenization and subsequently incubated at $20^{\circ}C$, proteloysis attributable to muscle cathepsin was not detected. In the second with rockfish muscle aseptically prepared from freshly killed fish, the samples were inoculated with a proteolytic strain of fish spoilage Pseudomonad or irradiated at 0, 0.5 and 3.0 Mrad. The four samle groups were stored at $0-2^{\circ}C$ to compare the spoilage pattern of sterile and non-sterile muscle. In sterile muscle both total-N (extracted in 0.5M KCl) and amino-N $(soluble\;in\;70\%\;ethanol)$ declined slightly while the inoculated muscle showing increase in parallel with the increase of number of inoculated bacterium. The results indicate that proteolysis is a part of normal fish spoilage and the onset of proteolysis is delayed until viable count reaches its maximum level. Contribution of fish muscle cathepsin to protein degradation in white flesh fish muscle post-mortem is nil.

  • The purposes of this study were to identify the contents and satisfaction level of the patients received home care service, and to compare the differences of the contents by the characteristics of the patients. Seventy eight patients received home care service from 1st Jan. to 30th Sept., 1996 were data-collected to analyze the contents and outcomes of home care service. Sixty-nine patients currently receiving home care service were participated to evaluate the satisfaction level of home care service. The data were analyzed using mean, standard deviation, $x^2$ test, and ANOVA by SPSS $PC^+$ program. The findings of this study were as follow : 1. The contents & outcomes of home care service 1) The mean age of the subjects was 64.4 years: 58% of them were female. Those who living in Seoul were 83% and the rest of the subjects was living in Kyung-Gi. 2) The subjects who had one diagnosis were 41%. Over 60% of them had the disease of neurologic & sensory system. 3) The mean number of visit was 6. Only one visit was 22%. The mean time of care was 79 minutes. Duration of visit from 31 minutes to 60 minutes were 47 %. The subjects who terminated the visit because of death were 67.3%. 62% of the persons who referred them to the home care service were nurses. 4) The pain after the service was more relieved than before. The amounts of intake, the degree of bed sore, edema & fracture after the service were more improved than before. Health status after the service was improved in general. 5) There were significant differences between initial and last conscious level in tracheostomy care & oxygen inhalation care. There was significant difference between initial and last degree of activity in blood sugar check. 6) There were significant differences on the number of visit in assessment of the status, evaluation & observation, vital sign check, skin care, injection, medication, bed sore care, colostomy care, relaxation therapy for pain relief, patient education, family care, exercise therapy, position change, supply of disinfected equipments and infection control. There were significant differences on visiting time in nasogastric tube care, drainage tube care and oxygen inhalation care. 2. The satisfaction level of home care service 1) 50% were male. Over 60 years of the subjects was 61 %. Those who living in Seoul were 82%. 2) The subjects who had one or two diagnosis were 32% respectively. 55% of the persons who referred them to the home care service were nurses. 3) Total level of satisfaction of home care service was very high. 4) The older the age, the higher the satisfaction level. The larger the number of visit, the higher the satisfaction level. 5) The subjects who were in cloudy state were higher level of satisfaction than in alert or coma state. The subjects whose activity were normal or who needed assistance were higher level of satisfaction than bedridden or immobilized subjects. These findings suggested that the patients had substantial need for posthospital care. They tended to be elderly and to have experienced the wide range of health problems associated with aging, chronicity, including limitations in activities, and other serious health problems. So, the nationwide home care systems beyond the limit of demonstration program by local association and the development of the effective financial system of home based health care are necessary for the clients who are in need of home care.

  • The objective of this study was to construct multi-element ultrasound applicators for the treatment of gynecologic cancer with high dose rate brachytherapy. For the treatment of uterus, piezo-ceramic crystal transducer (PZT -5A) with outer diameter of 4 mm, wall thickness of 1.3 mm, and length of 24.5 mm was selected. For the treatment of cervix or vagina, it should be possible to insert the applicator into the vagina. Thus, a cylindrical PZT -8 material with outer diameter of 24.5 mm, wall thickness of 1.3 mm, and length of 15.2 mm was selected. The operating frequencies determined by vector impedance measurement were 3.2 MHz for the PZT 5A cylinder (OD=4 mm) and 1.7 MHz for the PZT -8 cylinder (OD: 24.5 mm). The ratios of generated acoustic output power to applied electric power were 33% and 61% for the tandem type crystal and the cylinder type crystal, respectively. The radiated acoustic pressure fields from both transducers were calculated using a Matlab code and measured in water using hydrophone. There was good agreement between measured and calculated acoustic pressure field distribution. For a tandem type transducer, the calculated acoustic pressure field decreased from 0.023 MPa at 10 mm to 0.010 Mpa at 30 mm, the reduction of 57%. For the cylinder type transducer which will be used for the treatment of vagina showed 78% reduction at 15 mm and 66% at 25 mm as compared to values at 5 mm from the surface. Based on the characteristics of the transducers, this study demonstrated the possibility of using the crystals as a heating source. Finally, a 3-element and 4-element prototype applicators were constructed. The 3-element applicator is 75 mm long and 4 mm thick and will be used for the treatment of uterus. The 4-element applicator is 61 mm long and 24.5 mm thick and will be used for the treatment of vagina. Using these applicators, it is possible to generate enough power to increase temperature to therapeutic level.

  • In this paper, we evaluated the performance of 3D CRT, IMRT and three kind of RA plannings to investigate the clinical effect of RA with liver cancer case. The patient undergoing liver cancer of small volume and somewhat constant motion were selected. We performed 3D CRT, IMRT and RA plannings such as 2RA, limited triple arcs (3RA) and 3MRA with Eclipse version 8.6.15. The same dose volume objectives were defined for only CTV, PTV and body except heart, liver and partial body in IMRT and RA plannings. The steepness of dose gradient around tumor was determined by the Normal Tissue Objective function with the same parameters in place of respective definitions of dose volume objectives for the normal organs. The approach between the defined dose constraints and the practical DVH of CTV, PTV and Body was the best in 3MRA and the worst in IMRT. The DVHs were almost the same among RAs. Plans were evaluated using Conformity Index (CI), Homogeneity Index (HI) and Quality of coverage (QoC) by RTOG after prescription with dose level surrounding 98% of PTV in the respective plans. As a result, 3MRA planning showed the better favorable indices than that of the others and achieved the lowest MUs. In this study, RA planning is a technique that is possible to obtain the faster and better dose distribution than 3D CRT or IMRT techniques. Our result suggest that 3MRA planning is able to reduce the MUs further, keeping a similar or better targer dose homogeneity, conformity and sparing normal tissue than 2RA or 3RA.

  • This study was carried out in order to develop a biological control of anthracnose of red pepper caused by fungal pathogens. In particular, this study focuses on the Colletotrichum species, which includes important fungal pathogens causing a great deal of damage to red pepper. Antagonistic bacteria were isolated from the soil of pepper fields, which were then tested for biocontrol activity against the Colletotrichum gloeosporioides anthracnose pathogen of pepper. Based on the 16S rRNA sequence analysis, the isolated bacterial strain CS-52 was identical to Bacillus sp. The culture broth of Bacillus sp. CS-52 had antifungal activity toward the hyphae and spores of C. gloeosporioides. Moreover, the substances with antifungal activity were optimized when Bacillus sp. CS-52 was grown aerobically in a medium composed of 0.5% glucose, 0.7% $K_2HPO_4$, 0.2% $KH_2PO_4$, 0.3% $NH_4NO_3$, 0.01% $MnSO_4{\cdot}7H_2O$, and 0.15% yeast extract at $30^{\circ}C$. The inhibition of spore formation resulting from cellulase, siderophores, and indole-3-acetic acid (IAA), were produced at 24 h, 48 h, and 72 h, respectively. Bacillus sp. CS-52 also exhibited its potent fungicidal activity against anthracnose in an in vivo test, at a level of 70% when compared to chemical fungicides. These results identified substances with antifungal activity produced by Bacillus sp. CS-52 for the biological control of major plant pathogens in red pepper. Further studies will investigate the synergistic effect promoting better growth and antifungal activity by the formulation of substances with antifungal activity.

  • Backgrounds: Sticking warm and hot herbs to acupoint in Dog-Days where the strongest Yangqi takes place, Acupoint sticking in Dog-Days is one of Oriental medical treatment to cure winter diseases in the summer. This treatment is widespread in China and Taiwan, and is becoming popular in South Korea nowadays. Objectives: The research has been conducted to evaluate the influencial factors and efficacy in Acupoint sticking in Dog-Days. Methods: We visited one kindergarten in Dog-Days of 2010, and attached pills which are made of Sinapis Semen(白芥子), Corydalis Tuber(玄胡索), Asari Herba Cum Radix(細辛), Juice of Zingiber Officinale(薑汁) to BL-13(肺兪), BL-15(心兪), BL-17(膈兪) of 56 children for 4-6 hours(34 boys, 22 girls, $52.64{\pm}16.85$ months, 19-78 months). Exacerbating effect or non-significant changes in respiratory symptoms before and after the treatment were ified.. The influentialfactors of efficacy were analyzed by Pearson's $x^2$-test and Fisher's exact test. In addition, the efficacy and satisfaction among once, twice, and three times treatment groups were verified by ANOVA. Results: 27 children (48.2%) were effective, but efficacy felt by parents is 45 cases (80.4%). Sex, perspiration, stool, urine, sleep, cold of hands and feet, cold sensitivity, and frequency of Acupoint sticking in Dog-Days has no relation to efficacy(p>0.05). However, the efficacy is poor in 1 and 2 age(p=0.030). Difference among efficacy of once, twice, and three times treatment groups is not significant(p=0.069), whereas there are linear association in frequency of Acupoint sticking in Dog-Days and efficacy(p=0.030). 36 parents (64.3%) are satisfied with Acupoint sticking in Dog-Days, and we observed significant difference among once, twice, three times treatment groups(p=0.041). 19 parents (33.9%) had been known about Acupoint sticking in Dog-Days, but 53 parents (94.6%) wanted repetition, and 41 parents (73.2%) intended to recommend it to acquaintance. Side effects are minor itching in two cases. Twenty seven participants showed positive effect, and forty five people (80.4%) felt beneficial. Sex, perspiration, stool, urine, sleep, cold hands and feet, sensitivity in cold, and frequency of Acupoint sticking in Dog-Days has no relation to the efficacy(p>0.05). Though the efficacy was poor in one and two year old infants, it was linearly correlated with the frequency count and responses from the treatment (p=0.030). Thirty six participants (64.3%) satisfied with the treatment, and so did the first, second, and third participant groups (p=0.041). Even though, only nineteen participants (33.9%) were familiar with Acupoint sticking in Dog-Days, fifty three participants (94.6%) preferred to repeat the treatment, and 41 parents were preferable to recommend the treatment to others. Side effects of minor itching has been reported in a couple cases. Conclusions: Acupoint sticking in Dog-Days is effective in children older than three year old. The effect would be greater when going through the treatment three times. Based on significant satisfaction, intention of repetition and recommendation, strong promotion on Dog-Days are needed to make a better use of Acupoint sticking in Dog-Days for the effective treatment.

  • The chemical properties of olive and bay leaves were investigated and analyzed to provide basic data for food materialization and processing. The moisture contents of olive and bay leaves were $3.95\%$ and $8.50\%$, respectively. The contents of crude protein, crude fat, crude ash and carbohydrates of olive leaf were $11.04\%,\;7.45\%,\;5.05\%\;and\;76.46\%$, respectively. And the contents of same those components of bay leaf were $7.23\%,\;7.21\%,\;3.72\%\;and\;81.84\%$, respectively. Glutamic acid $(1086.8\;mg\%)$and aspartic acid $(918.8\;mg\%)$ in olive leaf were major amino acids, glutamic acid $(621.2\;mg\%)$ and leucine $(558.6\;mg\%)$ in bay leaf were the major amino acids. The major free sugar of olive leaf was sucrose $(1.55\%)$. Whereas major free sugar of bay leaf was glucose $(1.54\%)$. Palmitic acid $(olive\;33.0\%,\;bay\;17.8\%)$ and linolenic acid $(olive\;31.1\%,\;bay\;35.2\%)$ were major fatty acid in crude fat of both olive leaf and bay leaf. The Ca contents were the highest in olive leaf $(929.6\;mg\%)$and bay leaf $(836.2\;mg\%)$. Vitamin A contents of olive and bay leaves were 5.10 mg/100 g and 6.49 mg/100 g, respectively. Vitamin C contents of olive and bay leaves were 36.64 mg/100 g and 13.86 mg/100 g, respectively. But vitamin $B_6$ and $B_{12}$ were not detected.

  • In an attempt to analyze the clonorchicidal activity of linoleic acid and ethyl linoleate in vitro, the wormicidal effects on Clonorchis sinensis were chronologically monitored in dose titration experiments. Encysted metacercariae were killed within a period of 31, $0{\pm}4.0$ min, 149.3k4. 1 min and $207.0{\pm}13.5$ min with 100.0 mg, 0.1 mg and 0.001 mg linoleic acid, respectively. The time required for the linoleic acid to kill adult worms was 167, $0{\pm}0.8$ min with 100.0mg, $253.0{\pm}0.8$ min with 0.1mg, and $277.0{\pm}0.8$ min at 0.001mg titration. Clonorchicidal activity of ethyl linoleate was relatively delayed as death was observed within $263.3{\pm}2.9$ min, $286.0{\pm}0.5$ min, and $318.0{\pm}0.8$ min for 100.0 mg/ml, 0.1 mg/ml and 0.001 mg/ml concentrations, respectively. The wormicidal effects observed with these pure anti-clonorchal substances were found to be similar to the biological activity of native products derived from the mucus of the fresh water fish.

  • Worm recovery rates and pathologic changes in small intestine of albino rats were observed after concurrent and challenge infections with metacercariae (MCI of Fibricota seouLensis and MetaBonimus vokogaupci, and compared with those of single Infection groups. Albino rats In concurrent Infection group were killed 20 days after feeding with 1,000 MC of each fluke. Rats in challenge. infection group were fed with 1.000 MC of f seouleni,s and challenged by 1,000 MC of M. yokogawai 10 days after primary infection, then killed 10 days thereafter. In concurrent infection group, mean number of F. seoulensis and M. yokogawai recovered, 250 and 118 respectively, were similar to those of single infection groups. However, more flukes were collected from the duodenum and less flukes were from the ileum than from single infection group. In challenge Infection group, the recovery rate of F. seoulensis was similar to that of sin91e infection group and the distribution of thIn flukes was similar to that of concurrent infection group. Mean number of M. yokogculat, 69, was signiflcantly lower than that of single infection group. Its distribution, however, extended to the duodenum and most of the flukes were recovered from the jejunum. In concurrent infection group, villi of the duodenum were more markely thickened, fused and shortened than those in F. seoulensis sing1e Infection group. The crypt epithelium appeared to be hyperplastic and inflammatory cell infiltration into the villous stroma was mild. Villous atrophy in the jrlunum and ileum was ndlder than in M. yokogawai single infection group. In challenge Infection group, the fhldlngs were simuar to those of concurrent Infection group. Crypt epithelium hyperplasla was not severe in duodenum. Inflammatory reaction was observed in submucosa of the Jrjunum and ileum. From the above results, it Is considered that F. seoulenis ikabiting in upper part of small intestine affect the settlement of M. yokoguwai introduced later In lower part of the intestine.
