  • This study was designed to examine effects of $\alpha$$_2$-Adrenergic Antagonists on blood chemical values in xylazine-sedated dogs. Twenty-four crossbred dogs of both sexes were intramusculary injected with a standard dosage of xylazine(2.2mg/kg of body weight). Righting reflex was uniformly lost and considered to be the point of maximum sedation. When the dogs were maximally sedated, tested groups were in-travenously injected with yohimbine 0.125mg/kg, 4-aminopyridine(4-AP) 0.3mg/kg, and a combination of yohimbine with 4-AP. Control group was intravenously 1 $m\ell$ of physiological saline solution. Total protein(T.P), albumin, glucose, aspartate aminotransferase(AST), alanine aminotrnasferase(ALT), blood urea nitrogen(BUN) were analyzed in the conditions of 0-, 30-, 60- and 120-minute after the administration of drugs. The results obtained in the study were as follows. 1. Changes of T.P, albumin, AST, ALT and BUN values in the control group were not significant during or after xylazine administration for at least 120minutes. 2. No changes of T.P, albumin, AST, ALT and BUN values in the tested groups were observed during or after $\alpha$$_2$-Adrenergic Antagonists treatment. 3. Serum glucose values of control group were getting remarkably increased after xylazine injection. 4. The xylasine-induced hyperglycemia was reversed in the dogs administrated with $\alpha$$_2$-Adrenergic Antagonists. Therefore, the results of the study show that the combined treatment with antagonists may be useful for accidental overdoses of xylazine and rapid reversal of animals sedated with xylazine.

  • BACKGROUND/OBJECTIVE: The blue honeysuckle berry (Lonicera caerulea var. edulis L.) is a small deciduous shrub belonging to the Caprifoliaceae family that is native to Russia, China, Japan, and Korea. The berry of this shrub is edible, sweet and juicy and is commonly known as the blue honeyberry (BHB). This study examined the anti-diabetic potential of BHB on high-fat-diet-induced mild diabetic mice. The hypoglycemic, and nephroprotective effects of the 12-week oral administration of blue honeyberry extract were analyzed. MATERIALS/METHODS: The hypoglycemic effects were based on the observed changes in insulin, blood glucose, and glycated hemoglobin (HbA1c). Furthermore, the changes in the weight of the pancreas, including its histopathology and immunohistochemical investigation were also performed. Moreover, the nephroprotective effects were analyzed by observing the changes in kidney weight, its histopathology, blood urea nitrogen (BUN), and serum creatinine levels. RESULTS: The results showed that the high-fat diet (HFD)-induced control mice showed a noticeable increase in blood glucose, insulin, HbA1c, BUN, and creatinine levels. Furthermore, growth was observed in lipid droplet deposition related to the degenerative lesions in the vacuolated renal tubules with the evident enlargement and hyperplasia of the pancreatic islets. In addition, in the endocrine pancreas, there was an increase in the insulin-and glucagon-producing cells, as well as in the insulin/glucagon cell ratios. On the other hand, compared to the HFD-treated mice group, all these diabetic and related complications were ameliorated significantly in a dose-dependent manner after 84 days of the continuous oral administration of BHBe at 400, 200 and 100 mg/kg, and a dramatic resettlement in the hepatic glucose-regulating enzyme activities was observed. CONCLUSIONS: By assessing the key parameters for T2DM, the present study showed that the BHBe could act as a potential herbal agent to cure diabetes (type II) and associated ailments in HFD-induced mice.

  • Objectives : To prove the channel-tropism theory in herbology, we investigated the anti-diabetic effect of six herbal plants used for lower wasting-thirst in streptozotocin-induced diabetic rats. Methods : Diabetes was induced in male Sprague-Dawley rats by consecutive injection of streptozotocin (30 mg/kg i.p.) for 5 days. The rats were divided into normal control, diabetic control, and diabetic treatment with Lycii Radicis Cortex (LRC, 300 mg/kg); Corni Fructus (CF, 300 mg/kg); Bombyx Batryticatus (BB, 50 mg/kg); Lycii Fructus (LF, 300 mg/kg); Phellodendri Cortex (PC, 300 mg/kg); Epimedii Herba (EH, 300 mg/kg); and glibenclimide (10 mg/kg) as a reference drug. Herbal extracts or reference drug were administered orally for 28 days. The changes of body weight, food intake and water intake, and serological markers such as blood glucose, serum total cholesterol, triglyceride (TG), blood urea nitrogen (BUN), and creatinine (Cr) were measured. Results : The decrease of body weight and the increase of food and water intake in STZ-induced diabetic rats was improved by the administration of CF and LF. Also, the enhancement of blood glucose and serum total cholesterol, TG, BUN and Cr in STZ-induced diabetic rats was significantly inhibited by the administration of CF, BB, LF and glibenclimide. On the other hand, EH strongly inhibited the increase of BUN and Cr in the sera of STZ-induced diabetic rats. Conclusions : These results suggest that among six herbal medicines used lower emaciation of emaciation-thirst disease, CF, BB, LF and EH show a characteristics including the channel-tropism theory.

  • 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.

  • Objective : The purpose of this study was to investigate the risk factors of dehydration from the subjects who underwent anthropometric and blood parameters testing during a comprehensive health screening. Methods : For the study analysis, 5,391 samples with valid data of the levels of Sodium($Na^+$), BUN (Blood Urea Nitrogen) and FBS(Fasting Blood Sugar) were selected to calculate a dehydration indicator of plasma osmolality. The study data was collected from the health screening examinees who visited Sahmyook Medical Center Seoul Adventist Hospital Comprehensive Health Check-up Center from 2014.01.01 to 2015.12.31. The relationship between dehydration and age group, BMI, disease exposures(hypertension, diabetes mellitus, dyslipidemia, kidney disorder) were analyzed by gender. Results : The odds ratio of dehydration showed statistical significance from age ${\geq}50$ in both male and female, respectively. The female obese group was vulnerable to dehydration while the male study group showed no statistical significance in the BMI difference. The disease exposed groups(hypertension, diabetes mellitus, dyslipidemia, kidney disorder) were vulnerable to dehydration. Also, the more types of disease carried by the exposed patients, the higher odds ratio and susceptibility to dehydration. Conclusions : Aging, increasing BMI, and exposed to diseases were found to be the risk factors for vulnerability to dehydration. To prevent dehydration, special caution to be taken for those in the ${\geq}50s$ group, along with controlling BMI and chronic diseases. Further studies are suggested to investigate the risk factors of dehydration that may affect increasing plasma osmolality as a potential stimulus mechanism in disease outbreaks.

  • This study was performed to evaluate the effects of reduced L-glutathione on the oxidant/antioxidant status(superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase(GPx), protein carbonyl and lipid hydroperoxide(LPO) concentration), renal function(blood urea nitrogen(BUN) and serum creatinine levels), and microscopy of renal tissues in pigs undergoing unilateral renal ischemia-reperfusion(I/R). Sixteen Landrace and Yorkshire mixed-breed pigs were divided randomly into two groups: untreated control group and reduced L-glutathione-treated group(4 mg/kg IV). Each group had 8 pigs. Pigs were unilaterally nephrectomized and the kidney was subject to 30 min of renal pedicle occlusion. Blood samples for biochemical assay were collected on days 1, 3, 5, 7, and 14 post nephrectomy. Renal I/R injury were evaluated histopathologically by the microscopic observation of renal tissue sections and biochemically by the measurement of the plasma creatinine and urea levels. Parameters of oxidative stress such as SOD, GPx, CAT, protein carbonyl and LPO were measured. The elevation of creatine and BUN levels was lower in the treated group, compared with the control group. The activities of antioxidant-enzyme were higher in the treated group, compared with the control group. In histological findings, the severity of damage in the reduced L-glutathione treated group was less when compared to the control group.

  • This study was conducted to investigate effects of honeybee venom (Apis mellifera L. BV) on the calving, the growth performance and blood chemistry occurrence of Hanwoo calves. A total of twenty, a 3 day old male experimental calves were allocated into four groups, BV treated (0.05 mg/kg, 0.1 mg/kg and 0.2 mg/kg BV, n=5, respectively) and non-treated (n=5, Control) of Hanwoo calves in Icheon, Kyonggi province. Treatment of BV in calves increased body weight and weight gain during 60 days compared with control group. The concentrations of IgG in blood were significantly increased in BV groups compared with control at 60 days after treatment with BV. Cholesterol and glucose concentrations in BV group were significantly lower with control at 60 days. There were no differences in plasma biochemical components including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphate (AKLP), total protein, albumin, globuline, total bilirubin, creatinine, blood urea nitrogen (BUN) and $Ca^+$. In conclusion, the BV treatment had effect on growth, the score of the calf scours and blood biochemical profile.

  • Objective: The objective of the study was to determine the effects of increasing levels of metabolizable protein (MP) on lactation performance and nitrogen (N) efficiencies in lactating dairy cows. Methods: Nine multiparous cows in mid lactation [$113{\pm}25$ days in milk] received three treatments in a $3{\times}3$ Latin square design with a period length of 21 days. The treatments were three diets, designed to provide similar energy and increasing supply of MP (g/d) (2,371 [low], 2,561 [medium], and 2,711 [high] with corresponding crude protein levels [%]) 15.2, 18.4, and 20.9, respectively. Results: Increasing MP supplies did not modify dry matter intake, however, it increased milk protein, fat, and lactose yield linearly. Similarly, fat corrected milk increased linearly (9.3%) due to an increase in both milk yield (5.2%) and milk fat content (7.8%). No effects were observed on milk protein and lactose contents across the treatments. Milk nitrogen efficiency (MNE) decreased from 0.26 to 0.20; whereas, the metabolic efficiency of MP decreased from 0.70 to 0.60 in low to high MP supplies, respectively. The concentration of blood urea nitrogen (BUN) increased linearly in response to increasing MP supplies. Conclusion: Increasing MP supplies resulted in increased milk protein yield; however, a higher BUN and low MNE indicated an efficient utilization of dietary protein at low MP supplies.

  • The renoprotective activities of white ginseng radix and rootlet were compared in spontaneously hypertensive rat (SHR) with diabetes. During oral administration of white ginseng radix (Ginseng Radix Alba, GRA) and white ginseng rootlet (Ginseng Radix Palva, GRP) for four weeks, arterial blood pressure and blood glucose levels were determined at every 10 days. In both GRA- and GRP-treatment groups, arterial blood pressures started to go down after 10 days of administration and maintained throughout the study period. After four weeks administrations of GRA and GRP, diastolic blood pressures were significantly decreased with 17% and 9%, respectively. GRA treatment also decreased blood glucose levels after 10 days of administration when compared with diabetic SHR group. At the end of the experiment, serum creatinine (Scr) and blood urea nitrogen (BUN) were not significantly different between the groups, except 62% higher value of BUN in diabetic SHR group when compared with SHR group. In the diabetic SHR group, the excretion of urinary albumin was increased significantly when compared with SHR. The level of urinary albumin in GRA treated group was markedly reduced when compared with diabetic SHR group $(67.8{\pm}4.7\;vs.\;131.3{\pm}13.5\;mg/24\;h).$ To examine the effects of ginseng radices on an overt diabetic nephropathy, index of kidney hypertrophy and transforming growth $factor-{\beta}1\;(TGF-{\beta}1)$ protein levels were evaluated. The glomerular and tubular cells stained positive for $TGF-{\beta}1$ seemed to be more abundant in diabetic SHR than in those with SHR, and GRA treated rats showed somewhat less $TGF-{\beta}1$ protein in glomerular and tubular cells when compared with diabetic SHR. Our results suggest that GRA might be a useful antihypertensive and antidiabetic agent with renoprotective effect.
