The effects of the mouth care using cool sterile normal saline on oral stomatitis were investigated in 59 patients on chemotherapy. The subjects were divided into two groups, one was experimental group(N=31) in which the subjects were provided mouth care 4 times a day (after meals, before bedtime)with cool normal saline, the other was the control group(N=28), The Oral Assessment Guide(OAG) which it includes eight items(voice, swallowing, lips, tongue, salivation, oral mucous membrane, gingiva & teeth) was used to assess oral status six times(once in the Prechernotherapy Period, and on the third, 5th, 7th, 10th & 14th day postchemotherapy). The means of the total scores at each time were analyzed by repeated ANOVA The results are as follows : 1. The incidence of stomatitis was higher in the control group than in experimental group. The incidence of third grade stomatitis characterized by bleeding, sore, infection & severe pain was 3.3% in the experimental group, and while 21.4% in the control group(p=0.01). 2. The number of stomatitis sites which were occurred in the experimental group were significantly lower than in the control group(p=0.046). 3. The grade of stomatitis(mean of total score) for patients in the control group was significantly higher than for patients in the experimental group (p=0.005). 4. In the control group, voice change increased in the period between the seventh and tenth day after chemotherapy (p=0.04). 5. In the control group, swallowing difficulty was mest severe in the period between seventh and tenth day(p=0.05), and decreased by the fourteenth day(p=0.01). 6. Changes in the lips gradually increased after chemotherapy in the control group(p=0.0025), while they were significantly lower in the experimental group(p=0.0002). 7. The increment of tongue changes started on the third day after chemotherapy reached a peak on the tenth day and decreased by the fourteenth day in both groups(p=0.0016). 8. Driness of the mouth reached a peak on the seventh day after chemotherapy in the control group (p=0.05). 9. The degree of oral mucositis was significantly higher in the control group than in the experimental group(p=0.02) . In the control group, the mucosal change started three days after chemotherapy and reached a peak on the tenth day(p=0.03). 10. Changes in the gingia were significantly higher in the control group(p=0.03). In control group, the degree of gingivitis reached a peak on the tenth day. In conclusion, meuth care with normal saline four times a day could reduce the incidence and grade of stomatitis. Stomatitis was shown to begin on the third day after chemetherapy, reach a peak on the tenth day and be reduced by fourteenth day.

The objective of this study was to evaluate the effect of electric fan installation for milk production improvement of dairy cattle in Thailand. The study was conducted using 2 small-holder dairy farms in Chiang Mai province, during April to August 2004. Electric fans were installed in front of each row of cows. Each of the two rows of cows in the barn was defined as an experimental unit, thus each farm had two experimental units. The fans were operated alternately in 7-day intervals between rows of cows within each farm during the day or between 8.00 am to 8.00 pm. Non-operation periods were used as control. Milk yields were recorded. Data on environmental temperature and humidity were obtained from Chiang Mai Meteorological Center. Result from statistically analysis of milk record suggested an interaction between lactation period and fan installation. Therefore, this interaction term of lactation period and fan installation (PERIOD_FAN) was added as a variable to the regression model. Due to the repeated data collection of milk yield from the same cow (alternate week), milk yield was analyzed by repeated measure analysis (Mixed model). Least square means were calculated for all levels and used to compare between each pair-wise values. The final data were collected from the total of 18 cows with 2,072 data. Overall means and SEM of milk yields and days in milk separated into farm were $14.7{\pm}0.06kg/day$ and $176.3{\pm}2.2days$, and $15.2{\pm}0.22kg/day$ and $202.5{\pm}3.7$ days for farm A and farm B, respectively. For multivariable analysis, only PERIOD_FAN and humidity were significantly associated with milk yield. Only the first period of lactation showed that the amount of milk yields during fan installation was higher than that of non-fan installation (p<0.05). Cows with fan installation produced approximately 1.2 kg/cow more milk than cows without fan installation during this period. In conclusion, the use of electric fan operated during the day time increased milk production of cows during the first period of lactation.

The aim of this study was to examine the correlation between bovine casein (CN) mRNA expression levels in mammary epithelial cells and lactation period, the yields of milk proteins and other parameters. The cells were collected from each cow's milk, which contained somatic cell counts (SCC) of less than 100,000 cells/ml. The levels of ${\alpha}s1-$, ${\alpha}s2-$, ${\beta}$- and ${\kappa}$-CN mRNA expression were significantly correlated with each other in mammary epithelial cells (p<0.01). All cows produced either less than 30 kg/day/cow or a over 30 kg/day/cow level of milk yield (MY). It was shown that the CN mRNA expression levels decreased gradually from the calving period to late lactation, when MY was over 30 kg/day/cow. The SCC tended to increase gradually during the course of lactation, but it was negatively correlated with milk protein and CN yields (p<0.01) when MY was less than 30 kg/day/cow. Moreover, there was a tendency for a negative correlation between SCC and ${\alpha}s1$-CN and ${\beta}$-CN mRNA expression level, when MY was less than 30 kg/day/cow (p<0.05).

The purpose of this study was to enhance the quality of kochujang Apple juice was added to traditional Kochujang at 0%, 20%, 40%, 60 and 80%. Physicochemical and microbial characteristics were periodically investigated during at room temperature during a 90 day fermentation period. The moisture content of the apple Kochujang was higher than that of the control, while the salt content of the apple Kochujang was lower than that of the control, At first, the sweetness of the apple Kochujang showed no significant difference from the control; however, its sweetness increased during the 90 days. In all treatments, the pH value decreased during the fermentation period, while the titratable acidity increased during the fermentation period. Viscosity decreased greatly after 30 days. Sugar reduction was higher in the apple Kochujang than in the control, and its concentration increased with apple juice content. According to the analysis of free sugar, glucose, fructose, and maltose had an especially high ratio in the apple Kochujang. The organic acids detected in Kochujang were citric acid, malic acid, oxalic acid and lactic acids. The content of citric acid and malic acid were higher than the other acids in the apple Kochujang. L, a, and b values generally decreased during the fermentation period. When the Kochujang was made, the number of the total viable cells was $10^7\;CFU/g$. At room temperature, the number steadily increased up to the 30th day, then steadily decreased on the 90th day. After that, there was no significant change. The number of yeasts was $10^6\;CFU/g$ at the end of the 90th day. After the 90th day of fermentation, sensory results showed that the 60~80% apple juice Kochujang showed the best taste, appearance, texture, and overall quality.

The aim of this study was to evaluate the growth performance between two different crossbred strains of Korean native chickens denoted as 1A and 2A compared to white semi broilers and Ross (RR) from hatching to 40 days. In total, 576 one-day-old chicks were allocated in a completely randomized design to give 18 replicate cages each (eight chicks per cage). The two-phase feeding program consisted of the starter (day 1 - 21: Crude protein [CP] 20% and metabolizable energy [ME], 3,050 kcal·kg^-1) and the grower (day 22 - 40: CP 18%, 3,100 kcal·kg^-1). The results revealed that 1A and 2A had a lower (p < 0.05) body weight (BW) from day 1 to day 40 compared with the other groups. A lower (p < 0.05) average daily gain (ADG) was observed in 1A and 2A during the entire period when compared with the other groups. The 1A and 2A groups had the minimum (p < 0.05) average daily feed intake (ADFI) compared with the other groups for the whole period. The RR had an improved (p < 0.05) FCR compared with the other groups during the whole period. The 1A and 2A groups were observed to have the lowest (p < 0.05) shank length compared with the other groups during the entire period.

This study was performed to establish a new parameter for estimating gestational age and predicting parturition day by ultrasonographic measurement of deep portion of telencephalic vesicle (DPTV) diameter in small dogs. Fetal head diameter (HD) and DPTV diameter were measured in 15 pregnant Pekingese bitches, from Day 15 to the parturition day, and evaluated the correlation between gestational age. HD was measured from day 29 of pregnancy to parturition day and increased from $4.9{\pm}2mm$ to $25.5{\pm}0.7mm$. Especially, from day 38 of pregnancy to parturition day, HD uniformly increased about 0.6 mm per day and was significantly and linearly relative to gestational age during this period ($r^2$ >0.99). DPTV diameter was measured from day 35 to day 60 of pregnancy and increased from $3.2{\pm}0.9mm$ to $11.5{\pm}0.7mm$. Especially from day 38 to day 60 of pregnancy, DPTV diameter uniformly increased about 1 mm per 3 days and was significantly and linearly relative to gestational age during this period ($r^2$ >0.99). In conclusion, DPTV diameter could to be a useful parameter for the estimation of gestational age and the prediction of parturition day when used alone or in combination with HD during the second half of pregnancy.

The aim of this study was to provide basic haematological information to allow improved nutritional management for velvet production in spotted deer (Cervus nippon) by investigating biochemical changes in blood values during the antler growth period. Blood samples, obtained from the jugular vein of twenty-five deer, were taken every 10 days from casting (day 0) to harvesting (day 50) of velvet antler. Negligible changes were found in the concentrations of total protein, albumin, and creatinine during the antler growth period, but there were significant changes in the concentrations of urea (p<0.05) and uric acid (p<0.01). The concentration of triglyceride was significantly higher (p<0.05) during the antler growth period compared to casting time, while serum high-density lipoprotein concentrations were low and remained unchanged during the antler growth period. Serum glucose concentration increased (p<0.05) significantly and was slightly changeable during antler growth. The serum concentrations of Ca and P did not fluctuate during antler growth, while those of Na, K and Cl showed slight differences between the time of casting and the rest of the antler growth period. No significant changes in concentrations of AST, ALT, amylase, CK, GGT and LDH were detected during the antler growth period. However, the concentration of ALK-P increased during antler growth reaching its peak on day 50 after casting. We found a significant difference in the concentration of ALK-P between the time of casting and the rest of the antler growth period (p<0.01). Consequently, antler growth was associated with mild changes in measured serum biochemical values with the exception of ALK-P activity in spotted deer.

This study investigated the effect of the addition of alcohol on the quality change of Chungkukjang during the aging, The Cung-kuk-jang was made by the degree of 3, 5, 10%, respectively, and determined NH2-N, NH3-N, total acidity, cell numbers, lactate, succinate and phenolic acid to measure the change of flavor component in the aging of 2$0^{\circ}C$. 1. In the treatment groups of different amount of alcohol and salt added and aging period of Chung-kuk-hang, NH2-N was more decreased with more addition of alcohol and salt in the 3-and 10-day of aging. NH3-N was increased gradually in the addition of up to 2.0% alcohol and then decreased in the 3-and 10-day of aging. 2. In the treatment groups of different amount of alcohol added and aging period Chung-kuk-hang, the total acidity was more decreased with more addition of alcohol and higher degree of salt. Cell number was decreased rapidly with the addition of 1.0% alcohol in the 3-day and then decreased relatively and in the 10-day of aging, and it was increased with the addition of alcohol 3. With the addition of alcohol and the different growing temperature, the content of phenolic acid was more browning changed at 3$0^{\circ}C$ than that of at 2$0^{\circ}C$ and the phenol content of each group was decreased with increasing the addition amount of alcohol. Thus, the more addition of alcohol amount would the more extend the period of Chung-kuk-hang aging.
