In order to establish basic data of SAMP6 as an animal model for osteoporosis, present study has been designed to concentrate on the various biological aspects of SAMP6 such as growth index, hematology, blood biochemistry, biochemical characteristics, and bone and cortical thickness. Investigation period was for 15 months (3 months to 18 months of age) and biological characteristics have been examined throughout the study period. The results were summarized as follows : Decreased body weight of male SAMP6 was noticed from 7 months of age compared to from 18 months of age in female. Although there were no significant differences in organ weights, generally those of male mice were greater than those of females, especially in liver, kidney and lung. According to the analysis of blood biochemistry and hematology, the number of leukocytes in male mice was greater than that of female mice. There was a decrease in bone thickness in both male and female mice starting around from 7 months of age. Peak cortical thickness index was noticed at 5 months of age in both sexes. In femur, the highest $Ca^{2+}$ content for both sexes was noticed at 5 months of age, whereas the highest P$^{3+}$ content was noted at the age of 5 and 7 months in male and female mice, respectively. The contents of both elements were gradually decreased with age after peaks for both sexes. In summary, SAMP6 mice in KRICT colony show osteoporotic characteristics starting from 5 to 7 months of age, suggesting that at least 5 months of old animals should be used for studying the mechanism of osteoporosis or screening anti-osteoporosis drugs. This study also suggests that the cortical index thickness, $Ca^{2+}$ and P$^{3+}$ contents, and alkaline phosphatase activities can be used as indexes for drug screening.

The purpose of this study was to obtain reference data of parameters for hematological health diagnosis in marine fish and also evaluate application of veterinary chemistry analyzer used to those blood tests. A blood profile of total 522 fish for black rockfish (Sebastes schlegeli), red seabream (Pagrus major), rock bream (Oplegnathus fasciatu) and black seabream (Acanthopagrus schlegeli) cultured in mari-floating netcage of Gyeongnam province was determined by hematocrit (Ht), hemoglobin (Hb) and blood chemistry tests (total protein, albumin, alkaline phosphatase, blood urea nitrogen, lactate dehydrogenase, triglyceride, total cholesterol, creatinine, aspartate aminotransferase, alanine aminotransferase, glucose). Ht was measured by microhematocrit method. Hb and plasma chemistry were analysed by establishing baseline ranges for a dry chemical system of FUJI DRI-CHEM 3000. Actually recorded values of Hb and plasma chemistry by the analyzer were notably outside from the minimum and/or maximum of the established reference value. Albumin and alanine aminotransferase were not detectable in the range of 68～66%. Lactate dehydrogenase, total protein, alkaline phosphatase and glucose were not detectable in the range of 42～21%. Total cholesterol, aspartate aminotransferase, triglyceride, hemoglobin and creatinine were not detectable in the range of 18～3%. However, the values of blood urea nitrogen were below the detectable limits of the analyzer.

This study was conducted to make on-site survey on the output pattern and utilization situation of 19 by-products selected, to evaluate their nutritional characteristics, to find out a reliable index with which digestion of by-products can be predicted on the basis of chemical compositions analyzed and to diagnose the risk of using book values in the absence of the actual values analyzed for diet formulation. Production and utilization situations of by-products were quite various. Nutritionally, fruit processing by-products such as apple pomace (AP), pear pomace (PP), grape pomace (GP), and persimmon peel (PSP), and bakery by-products (BB) were classified as energy feeds. Soybean curd meal (SCM), animal by- products such as blood (BD), feather meal (FM) and poultry by-products (PB), and activated milk processing sludge (AMS) were classified as protein feeds. Soy hulls (SH), spent mushroom compost (SMC), barley malt hulls (BMH), waste paper (WP) and broiler litter (BL) were classified as roughage. Rumen contents (RC) and restaurant food waste (FW) were nutritionally analogous to complete diets for cattle and swine, respectively. Compared to soybean meal (SBM), BD and FM contained high (P<0.05) levels of amino acids and barley malt sprouts (BMS), AMS and FW contained low (P<0.05) levels of amino acids. Enzymatic (pepsin) digestibilities of proteinaceous feeds ranged between 99 and 66%. In vitro DM digestibility was high (P<0.05) in the order of FW, BB, AP, SH, PP, PSP, BMH, BMS, SCM, GP, RC, PB, BL, WP, SMC, AMS, FM and BD. In vitro DM digestibility had the highest correlation (r=0.68) with nonfibrous carbohydrate among chemical components. Differences between analyzed values of chemical components and book values were considerable. Caution is required in using book values when large amount of by-products are used in diets.

The present study was carried out to investigate the serum enzyme activities of racehorses. The enzymes investigated were aspartate and alanine aminotransferase (GOT, GPT), ${\gamma}$-glutamyl transpeptidase(${\gamma}$-GTP), Lactic dehydrogenase(LDH), creatine phosphokinase(CPK), and alkaline phosphatase(ALP). Animals used were 30 healthy racehorses(♀17, ♂13) average weighing 435kg and were from 2 to 8 years of age. LDH activity was progressively decreased with age and next in the order of GOT and CPK activities. GOT and ${\gamma}$-GPT activities were not changed with age but ALP activity tended to be decreased wish age. Activities of GOT, GPT, ${\gamma}$-GTP and ALP were higher in female than in male. There was no difference in CPK activity by sex, and no difference was found out among breeds.

Objectives: The purposes of this study were to investigate 1) the incidence of insomnia, 2) the clinical characteristics of the insomniacs, 3) the correlation of severity of insomnia with somatic complaints and psychological distresses, and 4) the beliefs and attitudes about sleep in patients with chronic renal failure on hemodialysis. Methods: The author evaluated 153 patients, receiving hemodialysis therapy at the four outpatients hemodialysis units in Pusan, Korea. The patients had completed a self-administered questionnaire package, which consisted of basic demographic findings, questions characterizing insomnia, Beck Depression Inventory(BDI), Spielburger's State-Trait Anxiety Inventory(STAI), and visual analogue scales measuring quantitatively the severity of the self-perceived psychological and somatic symptoms. And several laboratory data were collected. Diagnosis of insomnia was made in the base of insomnia criteria of DSM-IV and international classification of sleep disorders. Subjects were dichotomized into those who reported any characteristics of insomnia or those who had no insomnia during the preceding two weeks. Results: Insomnia was found in 100(65.4%) of 153 patients. No statistical differences were found between the patients with and without insomnia in terms of age, gender, education, marital status, mean duration of hemodialysis and all considered laboratory findings except serum albumin. The patients with insomnia had significantly higher BDI score and predialysis systolic blood pressure, and lower serum albumin as compared to non-insomnia group. Significant differences were found between two groups in terms of self-perceived distress such as sadness, anxiety, worry, pruritus, and dysfunction of daily life. The data showed statistically significant correlation between insomnia severity and some variables such as physical dysfunction, pruritus, bone pain, sadness, anxiety, worry, dysfunction of daily life and excessive daytime sleepiness. The patients with insomnia had significantly several dysfunctional beliefs and attitudes about sleep than those without insomnia. Conclusion: These results indicate that insomnia is very common in hemodialysis patients and likely contribute to the impaired quality of life experienced by many these patients. The author suggests that physical and psychological distresses would be reduced and the quality of life could be improved if their sleep disturbances are properly ameliorated in patients on hemodialysis.

To evaluate the physiological status of laying flocks, the blood chemistry values were measured and analyzed in various ages under different feeding conditions. Total 671 birds from 48 Hyline brown hens flocks from 13 different poultry farms were bled at the ages of day(s) 1, 11, 21, 50, 80, 120, 180, 240, 300, 400, and 500. The 17 blood chemistries including glucose, lipids, proteins, enzymes, electrolytes and metabolic by-products were measured with an autoanalyzer. Blood glucose showed the highest at the hatching day not relate with the dietary carbohydrates and energy, but tended to decrease during the rest of growth stage in hens. Total blood protein, albumin and globulin increased depending on the ages even though dietary protein was decreased. Blood lipid was greatly changed at different growth stages. Cholesterol was the highest at hatching period and maintained consistently until the 120 days of age. It was increased in birds after 180 days of age. HDL was also highest in hatchery, but decreased greatly after 180 days of age. However, TG was the lowest at one day old, but was increased up to 10 times after 180 days of age compared to that of one day old. The enzyme activities were different. AST, ALT, and GGT showed comparatively contained consistently, whereas amylase was slowly decreased. Blood P, Na, K and Cl showed consistency, but Ca content was increased upto two times of the one day of age. The results from this study showed that the blood chemistry values were affected by the general metabolic status of the host with ages not by feeding conditions. Further, the standard data of age-dependent blood chemistry values in the laying flocks were obtained, which can be utilized for early detection of the changes in the physiological status occurred by the infectious or metabolic diseases. The results of these analyses seemed to be useful to increase the productivity of laying flocks through rapid and proper veterinary medical treatments.

A 10-year-old Paint horse was presented with gradual changes in behavior, characterized as stallion-like including aggressiveness towards people and other horse. The abnormal right ovary was detected via transrectal ultrasonography and rectal palpation. A complete blood count and biochemical panel values were within reference ranges. The hormone analysis revealed increased testosterone 46.00 pg/mL and inhibin 0.856 ng/mL, and progesterone concentration consistent with absence of luteal tissue 1.2 ng/mL more than normal values. The purpose of the study reported was to describe a ovariectomy of enlarged ovary by using the diagonal paramedian approach. This method is useful to minimize surgical exposure and hemorrhage. This ovary was confirmed fibroma by histological examination post operation. Behavior problems and the hormone values were alleviated after surgery, and clinical signs of complication were not showed.
