Fifteen 1-yr old roosters were employed in order to investigate the influence of various dietary fibers on the water and Na metabolism of chicken. Wheat bran, pure cellulose and ground rice straw replaced corn in the control diet at 10% level; Pectin replaced corn at 8% level. Three roosters were allotted per dietary treatment and one rooster per replicate. The limit of probability accepted as being significant was P$\leq$.05. The dry matter metabolizabilities of cellulose and rice straw diets were significantly lower, and those of control and pectin diets were significantly higher than that of the wheat bran diet. Pectin fed roosters seemed to drink more water than did the other birds. Also, excreta from roosters fed the pectin diet were significantly wetter than those from other treatments. However, no difference in water intake and fecal moisture were found when !he roosters were colostomized. It was also found that the colostomized birds drank more water than did intact ones. Data of water holding capacity and bulk density of dried excreta showed that cellulose, rice straw and wheat bran in decreasing order were strong in fibrous property. There were no significant differences in C$_{Na+}$ , Cosm and C$_{{H_2}O}$ among all treatments. When the values of urine volume, urine osmolality and C$_{{H_2}O}$ were put together, it can be concluded that 11 out of 15 roosters developed diuresis. More severe diuretic symptoms were developed in roosters when they were fed more fibrous diets. In conclusion, when the four dietary fibers were graded in terms of fibrous property, it turned out to be pectin, cellulose, rice straw and wheat bran in decreasing order.

The Fluid and electrolytes balance in the body is of critical importance in maintaining good health. When the fluid and electrolyte imbalance is present, patients are in great danger. They must be assessed immediately by a nurse so that appropriate treatment can be started as soon as possible. Patients' fluid intake and output records contain highly important information for the diagnosis and treatment of fluid imbalance, but, these records are often inaccurate and the method of recording the fluid intake is not universal for every hospital. Be-cause they are few quantitative measurements of a patient's hydration, the need to improve the accuracy of fluid intake records is very important. However, very few studies have been done to investigate the accuracy of measurements of patients' fluid intake and output. The purpose of this study was to investigate the methods used for calculation of fluid intake which is most similar to fluid output in normal adults and hospitalized patients. This study focused on three different calculation methods for fluid intake and compared these to fluid output and developed suggestions as to the ideal way to record fluid in-take. Data for 43 hospitalized patients and 37 normal adults were analyzed. The findings of this study are as follows ; 1) In normal adults, the daily intake of water which enteres by the oral route was 2415m1 (the first method of calculation). The daily intake of water in the form of pure water or some other beverage was 1365m1 (the third method of calculation) The daily intake of water including fresh fruits and vegetables, rice, porridges, and Me m which have water content more than 80% were 2186m1 (the second method of calculation). 2) The urine output of the normal adults was 1350m1. This apprroximates the amount of fluid an adult takes in the form of pure water. 3) In patient group, the total intake of water was 2550m1 (the first method of calculation). The in-take of water in the form of pure water or as some other beverage and IV fluid was 1661m1 (the third method of calculation). The daily in-take of water including foods which have high water content was 2356m1 (the second method of calculation). 4) The urine output of the patient's group was 1728m1. This approximates the amount of fluid an adult takes in the form of pure water. 5) Investigation of the method of calculation of the patient fluid intake showed that among the 31 hospitals studied, only eight use the third method of calculation which reflects the most close value to urine output. From the results obtained in this study, it was indicated that the amount of fluid taken in the form of pure water reflects the most close value to urine output. Therefore, it can be suggested that the third method of calculation which includes water in-take only in the form of pure water or beverage should be used as patients' fluid intake record.

This work was conducted to investigate the amount and major compositions of excreta from broilers. One hundred fifty 1-d-old male and female Ross broilers were used in this work and ten broilers were selected to measure excreta. Average amount of excreta per broiler was 85.4 g, and average moisture content was 76.9%. N, $P_2O_5$ and $K_2O$ in excreta were 1.19, 0.29 and 0.49%, respectively. pH, $BOD_5$, $COD_{mn}$, and SS were 7.80, 42,134 mg/L, 52,668 mg/L, and 106,669 mg/L, respectively. Pb in poultry excreta was 0.803 mg/kg and highly lowed compared with the standard contents (150 mg/kg). Cd was not founded in excreta. Hg was founded in excreta as 0.002 mg/kg, but it was low compared with the standard level (2 mg/kg).

The present study was aimed to investigate whether ethanol-extract of Nelumbo nucifera has an ameliorative effect on the renal function in high fructose-diet induced hypertensive rats. The urine osmolality (Uosmel) was decreased in rats with high fructose-diet ($60\%$) during the whole experiment period without change of the urine volume (UV). The urinary excretion of sodium and chloride were decrease significantly in rats with fructose induced hypertensive rats, wheras urinary excretion of potassium was increased. The creatinine clearance (CCr) and solute-free water reabsorption were also decreased by treatment of fructose rich diet. Among these renal functional parameters, CCr was partially restored by the administration of ethanol-extract of Nelumbo nucifera. The Uosmol was also partially restored by the administration ethanol-extract of Nelumbo nucifera at the end of the experimental period. Taken together, ethanol-extract of Nelumbo nucifera has the ameliorative effect on glomerular filtration rate in rats with high fructose-diet induced hypertension.

This study was conducted to determine the volume of Holstein heifers manure excreted and its characteristics. The average dry matter intake of heifers was 6.7 kg/head/day. The intake rate was lowest in spring among four seasons. The average dry matter intake rate during spring, summer, fall, and winter was 4.6, 8.3, 7.1, and 6.8 kg/head/day, respectively. The average water intake of heifers was $19.3{\ell}/head/day$. The wale. consumption was highest value ($21.8{\ell}/head/day$) in summer and lowest values ($18.3{\ell}/head/day$) in spring and winter. Values were found not to be statiscally different for the four seasons. The average manure production of heifers (average live weight was 363.1 kg) was 20.3 kg/head/day and it was 5.6% of live animal weight. The manure production during spring, summer, fall, and winter was 13.7, 23.5, 25.0, and 20.2 kg/head/day, respectively. Production during spring was lower than the other seasons (p<0.05). A higher correlation between live weight and manure production ($R^2=0.7816$) and between live weight and feed intake ($R^2=0.7296$) was observed for heifers. Correlations between manure production and water intake and between manure production and feed intake were found to be relatively low for heifers. The moisture content of feces was 83.5% and that of urine 94.6%. The pH of feces and urine were in the ranges of 7.4 and 7.5, respectively. The $BOD_5$, COD, SS, T-N, T-P concentrations of the heifer feces were 18,048, 50,114, 119,833, 2,519, and $427mg/{\ell}$, respectively. Heifer urine showed lower levels of $BOD_5(5,434mg/{\ell})$, COD$(6,550mg/{\ell})$, SS$(825mg/{\ell})$, T-N$(3,616mg/{\ell})$, and $T-P(28mg/{\ell})$ than feces. The fertilizer nutrient concentrations of heifer feces was 0.25% N, 0.1% $P_2O_5$ and 0.14% $K_2O$. Urine was found to contain 0.36% N, 0.006% of $P_2O_5$ and 0.31% $K_2O$.

Last year, an epidemic of infantile urinary stone disease developed in China. Investigation revealed that melamine-tainted diary product caused urinary stone in these infants. Young infants were susceptible to the melamine toxicity and dehydration or other stone-prone factors aggravated the toxicity. Melamine-related urinary stones were small, multiple, and mainly composed of uric acid, thus conservative treatment of hydration and urine alkalinization worked well in majority of the patients.

Sawdust biofiltration is an emerging bio-technology for control of ammonia emissions including compost odors from composting of biological wastes. Although sawdust is widely used as a medium for bulking agent in composting system and for microbial attachment in biofiltration systems, the performance of agitated bed composting and sawdust biofiltration are not well established. A pilot-scale composting of hog manure amended with sawdust and sawdust biofiltration systems for practical operation were investigated using aerated and agitated rectangular reactor with compost turner and sawdust biofilter operated under controlled conditions, each with a working capacity of approximately $40m^3\;and\;4.5m^3$ respectively. These were used to investigate the effect of compost temperature, seed germination rate and the C/N ratio of the compost on ammonia emissions, compost maturity and sawdust biofiltration performance. Temperature profiles showed that the material in three runs had been reached to temperature of 55 to $65^{\circ}C$ and above. The ammonia concentration in the exhaust gas of the sawdust biofilter media was below the maximum average value as 45 ppm. Seed germination rate levels of final compost was maintained from 70 to 93% and EC values of the finished compost varied between 2.8 and 4.8 ds/m, providing adequate conditions for plant growth.

The effects of microbial feedstuff additives on feed conversion rate and physical and chemical characteristics of excreta in growing pigs were investigated. Three different products (A, B and C) were compared. Microbial population tests showed B contained higher numbers of total bacteria, Lactobacillus spp. and yeasts. The amylase activity of B was also higher than that of A and C. The daily feed intake rates fer control, A, B and C were 2.06, 2.13, 2.17 and 2.34 kg, respectively. Pigs feed product C had the highest liveweight gain(2.89 kg). However, the results of feed conversion rate were not significantly different between treatments. Amount of faces excreted for control, A, B and C was 1.18, 1,19, 1.23 and 1.32 kg, respectively. Urine volume for control, A, B, and C was 1.91, 1.80, 2.19 and 2.31 kg respectively. Moisture content, T-N, $P_2O_5$ and $K_2O$ in pig manure were not significantly different between treatments. The range of BOD values was 63,453 to $73,758mg/\ell$ for faeces, and 5,678 to $7,428mg/\ell$, for urine. SS values of solid and liquid excreta ranged from 142,200 to 176,000 and from 710 to $1,025mg/\ell$, respectively.

We investigated the cholesterol-lowering and body-weight loss effects of Cheonggukjang fermented using Bacillus subtilis DJI in rats fed a high-fat/high-cholesterol diet for 4 weeks. Weight-matched male Sprague-Dawley rats were assigned to one of four groups: a normal diet group (N), a high-fat/high-cholesterol diet group (HFC), a high-fat/high-cholesterol diet with DJI Cheonggukjang group (HFC-SCK), and a high-fat/high-cholesterol with commercial Cheonggukjang group (HFC-CCK). All of body weight and liver and adipose tissue weights increased in animals fed a high-fat/high-cholesterol diet, but decreased significantly in rats fed Cheonggukjang powder, compared with the HFC group. Food intake was lower in the HFC group than in the N group, and that of the HFC-CCK group was the lowest among the four groups. Serum total cholesterol levels were significantly lower in the Cheonggukjang-powder fed groups than the other groups. Serum phospholipid and HDL-cholesterol concentrations were significantly decreased in HFC animals and were markedly increased upon feeding of a Cheonggukjang-containing-diet. Levels of serum LDL-cholesterol, the atherogenic index, and cardiac risk factor assessment indications tended to be decreased in Cheonggukjang powder-fed groups, compared with the HFC group. The total cholesterol level in liver tissue was increased by feeding of a high-fat/high-cholesterol diet, and was significantly reduced when Cheonggukjang powder was present in the diet. The levels of total lipids and triglycerides in adipose tissues were lower in the HFC-SCK group than in the HFC group, whereas no significant differences were evidence when the HFC and the HFC-CCK groups were compared. Fecal weight, moisture level, and total lipid content increased in animals fed Cheonggukjang powder. The activities of HR-LPL and TE-LPL in adipose tissues were increased in the HFC group compared with the Cheonggukjang powder-fed groups. These results indicate that dietary Cheonggukjang may improve lipid metabolism and prevent obesity and hyperlipidemia.

The purpose of this study was to investigate the fluid balance of the patients who were either on soft fluid diet or total parenteral nutrition. We studied 19 patients with neurologic disorders and 22 patients with oromaxillary surgery who were admitted to either D university hospital in Choognam or S general hospital in Seoul between May and November 1995. The mean age for the patients who had oromaxillary surgery was 24 years and their average hospital stay was 9 days. The mean age of the patients with neurologic disorders was 54 years and they were bedridden for average of 71 days. For the maxillary bone surgery patients we did not limit the range of their activities in the ward during data collection period. The patients with neurological disorders were bedridden and did not move around the ward. They were all either on soft fluid diet, or total parenteral nutrition. The findings of this study are as follows ; 1) The difference of the triceps skinfold thickness between the baseline and the final measurement was 0.4cm for neurologic patient group and 0.5cm for oromaxillary surgery patient group. The difference was not statistically significant in each group. 2) In the oromaxillary surgery patient group, the daily intake of fluid in the form of pure water, other beverages, fluid diet as well as IV fluid was 4581m1 while urine output was 2979ml. The difference between fluid intake and output was statistically significant, indicating that fluid intake was far more than urine output. In neurologic patient group, the daily intake of fluid including water from fluid diet and IV fluid was 2701m1 whereas urine output was 2253m1 and they were statistically significant. 3) For a more accurate assessment we adjusted the fluid balance based on weight changes during data collection period. In the oromaxillary surgery patient group. the difference between fluid intake and output was 1238m1 after weight changes being adjusted. The difference was statistically significant, suggesting fluid overload in this patient group. In neurologic patient group, the difference between fluid intake and output considering weight changes was 124ml. The difference was not statistically significant, suggesting that the fluid intake and output was well balanced in this patient group.
