Few studies have shown the correlation between metabolic syndrome and bone mineral density (BMD). The main pathogenic mechanisms of metabolic syndrome rely on chronic low-level inflammatory status and oxidative stress. There are few studies that examine the gender-specific effects of inflammation and antioxidants on BMD. In this study, we evaluated the relative contribution of these factors in patients with metabolic syndrome. We conducted a cross-sectional study of 67 men and 46 postmenopausal women with metabolic syndrome; metabolic syndrome was defined as having three or more metabolic syndrome risk factors. BMD, body fat mass, and lean body mass were evaluated. We also examined the levels of high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6), adiponectin, vitamin E, and C in serum. Log-transformed hs-CRP levels were significantly higher in lumbar spine osteoporotic subjects than in normal subjects for women but not for men. There was no significant difference between the normal group and the osteoporotic group in other inflammatory markers. Stepwise regression analyses for BMD of the lumbar spine showed that lean body mass and vitamin E were significant determinants in men. Lean body mass and log-transformed hs-CRP were significant determinants in women Analysis for BMD of the femoral neck showed that lean body mass was a significant determinant for both men and women. There was no significant factor among the inflammatory markers or antioxidant vitamins affecting the femoral neck BMD for either gender. In conclusion, while hs-CRP is an independent predictor of the BMD of the lumbar spine in women, vitamin E showed profound effects on BMD in men but not women with metabolic syndrome.

In order to know the mode of the action of gondotrophic hormone on the expansion of cumuli oophori, oocyte-cumulus complexes isolated from Graafian follicles of mice were stimulated to expand in vitro with human chorionic gonadotrophin (HCG), and the effects of puromycin and actinomycin D on the expansion were examined. THe complexes were cultured in medium TC 199 containing 10% bovine serum in the presence or absence of HCG and the inhibitors. Puromycin in the medium (0.5-4 $\\mu$g/ml) suppresseed the HCG-induced cumulus expansion dose-dependently. This effect of puromycin was reversible. Puromycin affected the complexes throughout the HCG-stimulating stage (3 hours) and hyaluronic acid synthesis stage (3-18 hours). Actinomycin D also inhibited the expansion of the cumulus from the concentration of 0.025 $\\mu$g/ml. But the effect of actinomycin D was not completely reversible and the drug appeared to give an irreversible damage to the complexes at 0.1 $\\mu$g/ml. From the above results, it is suggested that RNA or protein synthesis is involved in the process in which HCG stimulates the cumulus cells to expand therefore cAMP elevated by te gonadotrophin may control expansion at the transcriptional or translational level.

This study was performed to compare propofol, thiopental, etomidate and diazepam plus ketamin as induction agents for the isoflurane anesthesia in dogs. Experimental groups were divided into low groups (thiopental group: thiopental 15 mg/kg IV, propofol group: propofol mg/kg IV, etomidate group: etomidate 1.5 mg/kg IV, DZP+KET group: diazepam 0.5 mg/kg + ketamine 5 mg/kg, IV) and each group was consisted of 4 dogs. Cardiorespiratory changes (heart rate, $SpO_2$, respiratory rate, End-tidal $CO_2$ and body temperature), blood serum chemistry values (alkaline phosphatase, alanine aminotransforase, and total protein), and recovery and walking time were measured. The end tidal carbon dioxide level was significantly increased in the thiopental group (P<0.05). Heart rate and respiratory rate higher in the DZP+KET groups. There was hypothermia in all groups and significant decrease in body temperature was showed in thiopental group (p<0.05). Mean arousal time and mean walking time were significantly longer in thiopental group (P<0.05). Cardiovascular stimulating effects were minimal in etomidate group. Etomidate provides uneventful and rapid recovery.

A 8-month-old, spayed female, Domestic shorthair cat lived in a shelter was presented with pelvic limbs ataxia and dysuria. Serum biochemical profile abnormalities were hyperproteinemia and decreased albumin/globulin (A:G) ratio (0.70). Results of cerebrospinal fluid (CSF) analysis were mixed cells pleocytosis with predominance neutrophils and an increase in protein concentration. In addition, feline coronavirus was detected by realtime RT-PCR in CSF. Magnetic resonance imaging (MRI) findings revealed lesions of the lumbar spinal cord. Based on clinical signs, MR finding, CSF analysis and realtime RT-PCR result in CSF, this case was diagnosed as feline infectious peritonitis (FIP) associated meningomyelitis. Although prednisolone and mycophenolate mofetil were administrated, clinical signs were not resolved and progressed to tetraplegia and coma status. This case presentation describes that feline infectious peritonitis virus could affect the lumbar spinal cord only and cause meningomyelitis with pelvic limbs ataxia without other neurological signs.

This study examined the effects of the daily noise stress on body weight, feed intake and clinicopathological findings in Korean indigenous goats. A total of 14 male goats was divided into 2 groups (test and control) with same number (n=7), and exam was started 2 weeks later. This study composed 2 stages. First was noise stage i.e., noise (80-100 dB) inflicted on the test for 70 minutes each time (5 times/day), and have continued for 2 months. Second was no noise for 2 months. Body weight and daily gain in stress group was decreased compared with control group after imposing noise (first stage). However, these results were reversed after ceasing noise (second stage). Average daily feed intake was not significant different between two groups throughout the experimental periods. But, feed conversion ratio was lowerin control group than another. Clinicopathological findings including total protein, albumin, globulin, total bilirubin, total cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose, amylase, blood urea nitrogen (BUN), cortisol, total leucocytes and hemoglobin value showed no significant different between stress and control group.

Objectives : We examined the effects of electroacupuncture on the cholecystokinin-octapeptide-induced acute pancreatitis in rats. Methods : Rats were administered with $75{\mu}g/kg$ cholecystokinin-octapeptide subcutaneously three times (1, 3 and 5h after shaving) for 5days. Three days after finishing cholecystokinin-octapeptide administration, high frequency electroacupuncture (100Hz) and low frequency electroacupuncture (2Hz) were applied to acupoint equivalent to ST36 (Zusanli) for 7 days. The author determined the pancreatic weight/body weight ratio, the levels of pancreatic heat shock protein HSP60 and HSP72. The author also assay the secretion of ${\beta}-amylase$, lipase and pro-inflammatory cytokines in serum. Repeated cholecysokinin-octapeptide treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. Results : Eelectroacupuncture significantly decreased the pancreatic weight/body weight ratio in cholecystokinin-octapeptide-induced acute pancreatitis, increased the pancreatic levels of HSP60 and HSP72, and decreased ${\beta}-amylase$ and lipase levels in cholecystokinin-octapeptide-induced acute pancreatitis. Additionally, the secretion of $Interleukin-1{\beta}$ and tumor necrosis $factor-{\alpha}$ was decreased in the animals treated with electroacupuncture. Conclusion : These results suggest that electroacupuncture may have protective effects against cholecystokinin-octapeptide-induced acute pancreatitis.

The effects of the an immunosuppressive drug cyclosporine A (CsA), on the salivary gland are largely unknown, even though clinical trials for the stimulation of salivation using CsA have been attempted. Cyclophilin A (CypA) is known to be a binding protein for CsA. CypA has cell proliferation and tissue matrix change activities. In our present study, the presence of CypA in the gland and effects of CsA on CypA expression were investigated by immunohistochemistry, immunoblotting and RT-PCR analyses. CypA was immunohistochemically detected in various kinds of ducts in the submandibular glands of Sprague Dawley rats. The CypA mRNA level was highest at postnatal day 1 and gradually decreased in a time-dependent manner up to adulthood. The expression of CypA increased after a 10 day subcutaneous administration of CsA in postnatal day 1 rats. Surgical sections of the chorda-lingual nerve with impaired salivation showed no changes in CypA expression. A cell proliferation assay using PCNA anti-serum showed increased cell division following CsA treatment. These results suggest that CsA and CypA may act on ductal cells to regulate saliva composition rather than salivation levels.

Purificationi of egg yolk immunoglobulin(IgY) was performed to understand the property of egg immunoglobulin. IgY differs from mammalian IgY in the molecular size(larger), isoelectric point(more acidic), and binding ability with mammalian complement and protein A(nonbinding ability). IgY is also known as ${\gamma}$-livetin and exists in egg yolk together with other two water-solubel proteins, ${\alpha}$-livetin(chicken serum albumin) and ${\beta}$-livetin(${\alpha}_2$-glycoprotein) and various lipoproteins(Low density lipoprotein, LDL and High density lipoprotein, HDL) which are the major components of egg yolk. The first step of isolation of IgY is to separate the water-solube proteins from lipoproteins. We report a simple method for separation of water soluble proteins using k-carrageenan and sedimentation. k-carrageenan was found to be effective for removal of yolk lipoprotein as a precipitate. IgY remained supernatant, and was isolated by chromatography on columns of DEAE-Sephacel and G 75 gel filtration chromatography.

The ability of fibroblasts attach to teeth is of paramount imporance in re-establishing the lost connective tissue attachment after periodontal therapy. Tobacco contains a complex mixture of substances including nicotine. various nitrousamines, trace elements. and a variety of poorly characterized substances. The effects of nicotine on fibroblasts have reported an altered morphology and attachment of fibroblasts to substrates and disturbances in protein synthesis and secretion. This study examined the effect of nicotine, a major component of the particulate phase of tobacco smoke, on human gingival fibroblasts and periodontal ligament cells attachment to tissue culture surfaces and cellular activity of human gingival fibroblasts and periodontal ligament cells. Pooled human gingival fibroblasts made from extraction of 3rd molar were utilized between passage 4 and 5 and plated in 96 well plate at 20,000 cells per well. Cell number were determined using 3-(4,5-dimethylthiazole-2-y)2,5-diphenyltetrazolium bromide(MTI) , which is reflection of mitochondrial dehydrogenase activity. The concentration of nicotine used were 0.025, 0.05, 0.1, 0.2 and $0.4{\mu}M$, the average serum concentration for a smoker being approximately $0.1{\mu}M$. The results were as follows : 1. Attachment effects of nicotine on human gingival fibroblasts and periodontal ligament cells Excepts of $0.4{\mu}M$, the effects on attachment with increasing numbers of cells attaching with increasing nicotine concentrations, compared to control group. But over the 60min, return to control value. 2. The effect of cellular activity on human gingival fibroblasts and periodontal ligament cells. The cellular activity of human gingival fibroblasts and periodontal ligament cells were similar or decrease to control value at 1st incubation day. At 2nd incubation day, 0.05, 0.1, 0.2, $0.4{\mu}M$ concentrations were statistically different from control value on gingival fibroblasts group. But at 3rd incubation day, cellular activities of all experimental group were significantly decrease than control group.
