Objectives: This case study reports the effectiveness of Korean medical treatment in a patient with cyclic vomiting syndrome. Methods: A 29-year-old female Korean patient with cyclic vomiting syndrome received acupuncture, electroacupuncture, herbal medicine, and moxibustion for 2 weeks in hospital. Changes in symptoms were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS), Visual Analog Scale (VAS), Index for Nausea, Vomiting, and Retching (INVR), Nausea Severity Scale (NSS), Nepean Dyspepsia Index-Korean version (NDI-K), quality of life using the Functional Dyspepsia Related Quality of Life questionnaire (FD-QoL), and gastric motility using electrogastrography (EGG). Results: Post-treatment, the patient showed high satisfaction and improvement in symptoms of nausea and vomiting. The following changes were observed in scores: GSRS: 23 to 19; VAS of nausea: 88 to 95; VAS of dyspepsia: 95 to 12; INVR: 13 to 1; NSS: 17 to 5; NDI-K: 107 to 78; and FD-QoL 84 to 27. We also found positive results in Channel 3 of EGG parameters, implying the improvement of gastric motility disorder. Conclusion: Korean medical treatment can be a therapeutic option for cyclic vomiting syndrome.

The term quality or freshness of eggs in industrial production still poses concerns regarding whether washing is necessary. Therefore, the aims of this study were to examine the effects of different storage times and temperatures and to perform a comparison between washed and unwashed eggs. A total of 1000 washed and 1000 unwashed egg samples were stored at three different temperatures (5, 10, and $25^{\circ}C$) for 0 - 8 weeks and were used for the data collection. On the designated day, the eggs were processed to evaluate their internal and external quality traits, such as the Haugh unit, airspace volume, eggshell strength, pH, and microbiological profile. Significant differences (p < 0.05) were observed between the washed and unwashed eggs for each quality trait. The results indicate that storage between 5 and $10^{\circ}C$ better preserved the quality of eggs compared with the storage at $25^{\circ}C$ throughout the days of the storage. Overall, this study suggests that the storage time and temperature have a vital role in maintaining the quality of eggs which were significantly affected during storage. In addition, all the quality parameters differed between the washed and unwashed samples which is further responsible for deteriorating the quality of the eggs.

This study conducted a diallel-crossbreeding test using four Korean native chicken parent stock lines (YC, YD, CK, and CF) to develop a native commercial layer with high egg-laying performance. A total of 312 chickens in six combinations were examined for various traits, including livability, body weight, age at first egg-laying, hen-day, and hen-housed egg production, egg weight, and egg quality, from hatching to 60 weeks of age. The results showed that the average survival rate was 77.1±18.8% with the YDYC combination having the highest survival rate along with excellent specific combining ability. The YDYC combination exhibited significantly higher body weight compared to the other combinations (P<0.01). The average age at first egg-laying was 121.3±2.5 days, with no significant difference between the combinations. The average hen-day egg production was 74.0±6.4%, and the hen-housed egg production was 181.4±33.8 eggs with the YDCF and YCCK combinations demonstrating the highest laying performance, while the YDYC and CKCF combinations had the lowest (P<0.05). Laying performance was more influenced by specific combining ability than general combining ability. The eggs from the YDYC combination were significantly lighter and had the darkest shell color (P<0.01), whereas the YDCF combination exhibited the thickest eggshells. There was no difference in internal egg quality among combinations, except the YDCF combination had the darkest yolk color. Overall, we concluded that the YCCK combination, characterized by high laying performance and livability, and the YDCF combination with high laying performance and good egg quality are the most desirable combinations for Korean native commercial layers.

The objective of this study was to investigate the effect of feeding organic acid mixture and yeast culture on the Performance and e99 quality of laying hens fur sixteen weeks. Four hundred and fifty 19-wk-old ISA Brown layers were alloted to five treatments with five replications of each. The supplemental levels of organic acid mixture(OAM) and yeast culture(YC) in the experimental diets were 0(control), OAM 0.1, 0.2%, and YC 0.1, 0.2%, respectively. Corn -Soy basal diet containing 16.0% CP and ME 2,770 kca1/kg ME. Eggs were collected and weighed every day. Eg3 Production, fred intake and fled conversion were recorded in every four weeks. Fatty acid composition of e99 Yolk, e99she11 breaking strength, thickness and Haugh unit were measured a(her every eight weeks. Egg Production and daily egg mass of birds fed 0.2% OAM and 0.1% YC tended to be higher than those of the other treatment groups. Egg weight was the highest in hens fed with 0.2% OAM treatment, but was not significantly different. Feed conversion of hens in all OAM and YC treatments was lower than those of control, but was not statistically different. Eggshell breaking strength of hens on OAM treatments tended to be higher than those of YC treatment and control. Haugh units of the birds fed OAM was significantly higher than controls (P<0.05). 599 yolk color score of OAM treatment was higher than those of YC treatments and control, but the difference was not significant. At 27-wk-old, arachidonnic acid content in eggs from the birds fed 0.1% OAM diet was significantly higher(P<0.05) than controls. The results of this experiment indicated that dietary organic acid mixture and yeast culture tended to improve the egg Production and internal egg quality.

A 3 yr experiment was conducted to evaluate the influence of diet and feeding location on animal performance, carcass characteristics, whole blood counts, and internal parasite burden of lambs assigned to 1 of 4 treatments: 1) confinement fed 71% alfalfa, 18% barley pellet, 5% molasses, 0.013% Bovatec, 6.1% vitamin/mineral package diet (CALF), 2) confinement fed 60% barley, 26% alfalfa pellet, 4% molasses, 2.5% soybean-hi pro, 0.016% Bovatec, 7.4% vitamin/mineral package diet (CBAR), 3) field fed 71% alfalfa, 18% barley pellet, 5% molasses, 0.013% Bovatec, 6.1% vitamin/mineral package diet (FALF), and 4) field fed 60% barley, 26% alfalfa pellet, 4% molasses, 2.5% soybean-hi pro, 0.016% Bovatec, 7.4% vitamin/mineral package diet (FBAR). A year × location interaction was detected for ending body weight (BW), average daily gain (ADG), and dry matter intake (DMI); therefore results are presented by year. In all years, cost of gain and DMI were greater for CALF and FALF than for CBAR and FBAR feed treatments (p ≤ 0.03). In yr 2 and 3 field treatments had greater ending BW and ADG than confinement treatments. For all years, diet did not affect ending BW or ADG. In yr 1 dressing percent and rib eye area were greater for field finished lambs than confinement finished (p ≤ 0.02) and Warner-Bratzler shear force was greater for CALF and FALF (p = 0.03). In yr 2 lambs in FALF and FBAR treatments had greater leg scores and conformation than CALF and CBAR (p = 0.09). In yr 1, FALF had a greater small intestine total worm count than all other treatments. In yr 1, ending Trichostrongyle type egg counts were greater for FALF (p = 0.05). In yr 2, ending Nematodirus spp. egg counts were greater for FALF and lowest for CBAR (p < 0.01). Abomasum Teladorsagia circumcinta worm burden was greater in CALF than all other treatments (p = 0.07) in yr 2. While field finishing lambs with a grain- or forage-based diet we conclude that it is possible to produce a quality lamb product without adverse effects to animal performance, carcass quality or increasing parasite burdens.

This study was conducted to assess the effects of flaxseed oil and dried whitebait as a source of ${\omega}$-3 fatty acids (${\omega}$-3 FA), which could be used to produce eggs enriched with ${\omega}$-3 FA, and of fructo-oligosaccharide (FOS) as a source of prebiotics on performance of hens (commercial Hy-Line Brown laying hens), and FA composition, internal quality, and sensory characteristics of the eggs. Dietary FOS increased egg weight. The amounts of ${\alpha}$-linolenic (ALA), eicosapentaenoic (EPA) and docosahexaenoic acids (DHA) in the eggs from the hens fed the flaxseed oil alone or flaxseed oil+dried whitebait diets were higher than those of the control. Hedonic scores for off-flavor, fishy flavor, buttery taste and overall acceptability of the eggs from the hens fed the diet containing flaxseed oil+dried whitebait were lower (p<0.05) than those of the control. Overall acceptability of the eggs from the hens fed the diet containing soybean oil+dried whitebait was lower (p<0.05) than that of the control. However, all the sensory attributes of the eggs from the hens fed the diet containing flaxseed oil, dried whitebait and FOS were not significantly different from those of the control. These results confirmed that flaxseed oil increases the ALA content in the eggs and a combination of flaxseed oil and dried whitebait increases EPA and DHA in the eggs. Of significance was that addition of FOS to the flaxseed oil+dried whitebait diet improves the sensory characteristics of the eggs enriched with ${\omega}$-3 FA.

Gestational diabetes mellitus (GDM) is defined as glucose intolerance discovered or onset during pregnancy and attention is needed because of increased risk of perinatal morbidties and higher incidence of diabetes afterward. This study was performed to identify dietary factors associated with the development of gestational diabetes mellitus (GDM). Developed food frequency questionnaire containing 192 food items were used to assess nutritional status of 246 control subjects and 104 GDM subjects. Food habits of subjects were examined in the questionnaire. The more irregularity and less variety of meal were found in GDM group compared to control group and GDM group tended to eat rapidly and do not like vegetables and greasy foods. Total score of food habits in GDM was lower than control group, which suggests that GDM group have undesirable food habits. Mean daily energy and carbohydrate intakes of GDM group were higher than those of control group, and percent energy from protein was significantly higher in control. Nutrient density of protein, calcium, phosphorus and vitamin BI of GDM group was significantly lower than those of control group. Therefore dietary quality of GDM group was lower than that of control group. Odds ratio for GDM was high when energy and carbohydrate intakes were high. And when the intakes of rice, noodle, shiruduk, hamburger, boiled egg, steamed pork shank were high, the odds ratio for GDM was high. These results indicate that the amount and frequencies of several foods and dish items were related with the occurrence of GDM subjects. On the whole, GDM subjects consumed more cereals and less vegetables and less legumes. From these results, pregnant women with GDM tended to have unhealthy food habits, and carbohydrate intake was important dietary factors on the onset of GDM.
