Ethylene glycol (EG) intoxication in dogs can pose a diagnostic challenge. We investigated the effect of a lethal dose of EG to the Shepherd on blood, urine test, and histopathologic observation. Shepherds were treated orally with EG at $10\;m{\ell}/kg$ body weight. Clinically, EG caused the vomition, depression of central brain. Anion gap was increased, which was decreased pH of blood, The blood osmorality was increased at 3 hours, and BUN and creatinine was increased at 24 hour significantly. The pH of urine decreased. The crystal of calcium oxalate appeared at 6 hours. The amount of crystals increased at 12 and 24 hours. Microscopically, the degeneration of proximal tubules were shown at 1 hour and finally progressed as acute tubular nephrosis at 24 hours. These results suggest that the blood and urine test accompanied with histopathological examination be helpful to investigate the EG intoxication.

Objectives: The purpose of this study was to examine correlation between Heart Rate Variability and urine analysis of women with urinary disturbance. Methods: We studied 34 patients visiting ${\bigcirc}{\bigcirc}$hospital from January 2010 to September 2010. The subjects were categorized in two groups, symptom group (n=11) and no symptom group(n=23). We studied the difference of Heart Rate Variability and urine analysis between two groups by Student T-test and correlation between Heart Rate Variability and urine analysis by Pearson's correlation coefficient test using SPSS for windows (version 17.0). Results: Occult blood of symptom group was significantly higher than no symptom group. SDNN, TP and HF of symptom group was significantly lower than no symptom group. Occult blood and SDNN, occult blood and RMS-SD, occult blood and HF significantly showed negative correlation coefficient. pH and TP, pH and LF significantly showed positive correlation coefficient. Conclusion: The results suggest that urinary disturbance can be related to decreased activity of autonomic nervous system. Also urine from women with urinary disturbance tend to show higher occult blood.

Purpose: A few Korean studies have reported that low urine acidity and hyperuricemia are related to metabolic syndrome. Therefore, we evaluated the relationships between urine pH, serum Uric Acid (UA), and metabolic risk factors in university students. Methods: Data were obtained from student health examinations in one university. Participants were 3,412 male and 4,214 female students. Descriptive statistics, t-test, logistic regressions and multiple logistic regression using SPSS version 18.0 were performed. Results: No significant relationship was found between metabolic risk factors and urine pH. From the univariate analysis, serum UA was significantly higher in obese ($BMI{\geq}25$), elevated blood pressure ($SBP{\geq}130$ and $DBP{\geq}85$), and higher triglyceride (${\geq}150$) groups for males and in obese, higher triglyceride and fasting blood sugar (${\geq}100$), and lower HDL-cholesterol (<50) groups for females. From the results of multivariate analysis, age, BMI, and triglyceride were significantly related to serum UA in males, BMI and HDL-cholesterol were significantly related to serum UA in females. Conclusion: Although there was no significant relationship between urinary pH and metabolic risk factors, significant associations between some of the metabolic risk factors and serum UA were found in the young adult population. Further studies are required to know the exact pathway between serum UA and metabolic syndrome.

Present study was undertaken in order to find out the most significant laboratory test for the early diagnosis of ethylene glycol poisoning in dogs. Seven dogs weighing from 5.0kg to 19.3kg were administered orally 6ml or l0ml of ethylene glycol per kilogram of body weight. In addition to clinical observations, blood samples were taken from the jugular vein on 0, 1, 3, 6, 12, 24 and 48 hours or until death after the adminisration and examined for the hematological, blood chemical, venous blood gas and electrolyte changes. Urine samples were simultaneously taken and examined for pH, protein, glucose and calcium oxalate crystals in the sediments. The results were as follows : 1. All dogs showed marked hypothermia in addition to the characteristic signs of ethylene glycol poisoning until death. 2. No significant hematological changes were observable after the administration of ethylene glycol except the secondary dehydration and stress leukogram. 3. Chemical values related to the liver function(serum glutamic pyruvic transaminase, total serum protein, serum albumin, serum total bilirubin) showed no significant changes during the experimental period in all dogs. 4. Chemical values related to the renal function(BUN and creatinine) showed significant(p<0.0l, p<0.001) increase from 24 hours to death in all dogs. 5. All dogs showed significant(p<0.01, p<0.001) decrease in blood pH from 3 hours to death after the ethylene glycol administration. 6. All dogs showed significant(p<0.05, p<0.01, p<0.001) increaes in anion gap from 1 hour to death after the ethylene glycol administration. 7. All dogs showed significant(p<0.05, p<0.01) decrease in urine pH from 1 hour to 6 hours after the administration of ethylene glycol. 8. Characteristic envelope form of calcium oxalate crystals were found in the urinary sediment from 6 hours after the administration of ethylene glycol in all dogs. 9. Histologically calcium oxalate crystals were found in the renal rubles in all dogs. 10. From these results, it may be concluded that the examinations of urinary sediments for the calcium oxalate crystals, blood or urinary pH and blood anion gap are most reliable tests for the early diagnosis of ethylene glycol poisoning in dogs.

Pulmonary function is the determinant of blood gas tension. However, Acid-Base disturbances can also alter partial pressures of oxygen and carbon dioxide in arterial blood. During respiratory acidosis $PO_2$ will be lowered and reverse changes will be produced during respiratory alkalosis. On the other hand, in metabolic acidosis $PO_2$ will be elevated and $PCO_2$ will be lowered by the respiratory compensation, and reverse response will be induced in metabolic alkalosis. Urinary gas tension has many influencing factors than arterial blood and difficult to estimate the tendency of its alterations. Urinary $PO_2$ and $PCO_2$ are not always identical level as venous blood. It is to be altered by blood gas tension, flow rate of urine, metabolic rate of kidney, and Acid-Base status of blood. Particularly countercurrent exchange of oxygen and carbon dioxide in the renal medulla will make larger alteration of gas tension than venous blood. After induction of Acid-Base disturbances [disturbances] arterial and urinary $PCO_2$, $PO_2$, urinary volume, and osmolarity were determined in dogs, and the relationships between arterial and urinary $PCO_2$ , $PO_2$ Acid-Base disturbances, urinary volume, and osmolarity were investigated. 1. During the acute Metabolic and Respiratory disturbances urinary pH did not respond on respiratory origin. However, there were immediate urinary response in pH on metabolic origin. 2. Urinary $PO_2$, $PCO_2$, did not always follow arterial or venous gas tension and Acid-Base disturbance. Urinary $PCO_2$, correlate well with the urinary volume. The larger the urinary volume, $PCO_2$ lowered to the venous level. The smaller the urinary volume, urinary $PCO_2$ tends to be higher. However urinary $PO_2$ did not have any particular correlation with urinary volume. 3. Correlation between urinary $PCO_2$ and $PO_2$ were inversely proportional to arterial blood. Differences of $PCO_2$ between arterial blood and urine also did not have any particular correlation with urinary volume. This may suggest that changes on blood gas tensions can influence on urinary $PCO_2$. 4. There were eminent clear inverse correlation between urinary $PCO_2$ and osmolar concentrations of urine. Above results strongly suggest that partial pressure of gas in urine primarily depend upon counter-current exchanges in renal medullary tissues.

The changes of acid-base status in vitro of the venous blood for 24 hours in ten Korean native goat were investigated. The acid-base parameters were measured within ten minutes after collection of the blood, and every hour during the first six hours and finally after twenty four hours of storage. Blood samples were stored at two different temperatures ($0-4^{\circ}C$ and $21-24^{\circ}C$). Twelve goats were induced acute acid-base disturbances by intravenous infusion of either hydrochloric acid or sodium bicarbonate and inhalated with $CO_2$ gas mixture (20% $CO_2$, 80% $O_2$) or hyperventilation were performed by means of respirator. The results were as follows; 1. Blood samples could be stored during the first two hours in ice water ($0-4^{\circ}C$) and one hour at room temperature without significant changes in pH. The magnitudes of changes were similar to those of cow, and lower than those of men and dogs. 2. The mean values of acid-base parameters in normal goat were arterial pH, 7.40; $P_{CO_2}$, 35.4mmHg; $HCO_3{^-}$, 21.8mEq/L. 3. Both the base excess and the bicarbonate showed high correlation (r=0.99) during the metabolic disturbance and were represented as $B.E.=1.38\;HCO^-{_3}-29.7$. 4. The slope of blood buffer curve obtained from the in vivo experiment was 16.3mEq/L/pH. 5. The magnitudes of changes in hydrogen ion concentration per unit change of $P_{CO_2}$ were 0.8nM/mmHg in hypercapnia and 1.0nM/mmHg in hypocapnia. 6. The ranges of acid-base parameters in normal goat urine were pH, 6.0-8.1; $P_{CO_2}$, 42-61mmHg; $HCO_3{^-}$, 2-110mEq/L. The concentration of potassium was higher (60-200mEq/L), and that of sodium was lower (8-70mEq/L) than those of human urine.

The urinalysis is an essential part of the diagnostic work-up for kidney disease and other renal system disorders. The dipstick test allows rapid and simultaneous chemical analyses of urine, including factors such as pH, specific gravity, protein, glucose, ketones, occult blood, bilirubin, urobilinogen, nitrite, and leukocyte-esterase. The chemical reactions on dipstick are complicated and can be affected by oxidizing, reducing, and discoloring substances in the urine. Therefore, false positive and false negative results are common in dipstick testing. To obtain reliable results with the dipstick, it is necessary to collect urine cleanly and examine the urine carefully. It is mandatory to clearly understand the principles of dipstick testing to evaluate abnormal findings. If the urine dipstick results suggest hematuria, proteinuria, or urinary tract infection, microscopy of the urine should be performed to confirm the findings.

This article is to investigate the effects of Euphorbia Pekinensis RUPR. on rats with acute renal failure induced by gentamicin sulfate. So this experimental research was focused on measuring (1)the levels of creatinine, blood urea nitrogen, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, total protein, sodium, potassium, chloride in the serum and (2)the levels of protein, blood, sodium, potassium, chloride, pH, specific gravity and volume in the urine and (3)intake water. The results were summarized as follows. 1. While the levels of creatinine and glutamic oxaloacetic transaminase, glutamic pyruvic transaminase in the serum were significantly increased, the level of BUN in the serum were partially increased and the levels of sodium and potassium in the serum were partially decreased on the Euphorbia Pekinensis $R_{UPR}$. group. 2. While the urine volume was significantly increased, the levels of protein, blood, sodium and chloride in the urine were partially increased and the specific gravity, pH in the urine were partially decreased. According to the above results, it is shown that Euphorbia Pekinensis $R_{UPR}$. without refinning had a diuretic effect on rats with acute renal failure induced by gentamicin sulfate, but aggravated the glomerular filtration rate and tubular reabsorption. So, it is supposed that Euphorbia Pekinensis $R_{UPR}$. without refinning needs to be used carefully on renal disease and futhermore research about the kinds of extracts form is necessary.

The effect of hemicellulose extracted from Shiitake mushroom(Lentinus edodes) on the level of blood sugar and cholesterol in the diabetes-induced rat by streptozotocin(STZ) was investigated. The yield of hemicellulose by extraction process of 5% salt extraction, preparation of alcohol insoluble substance, IN KOH extraction, acid precipitation(pH 3.0), and dialysis was 9.24%. The experimental plots divided to 1% cellulose group(control), 0.5% hemicellulose group(H-l) and 1% hemicellulose group(H-2). The groups were fed for 6 weeks, then continuously fed for 1 week after induction of diabetes by STZ. Feed intakes, weight gain and feed efficiency of the each groups were not significantly different, while water intakes and liver weight of H-2 group were lower than those of control and H-l group. Weight of liver in the H-2 group was significantly lower than those of control and H-l groups. The amounts of feces were 0.32 g/day in the control group, 0.43∼0.44 g/day in the H-l and H-2 groups, while the amounts of urine were 15.28 mL/day in the control group, 10.83∼11.20 mL/day in the H-l and H-2 groups. The content of blood glucose before diabetes induction(fed for 3∼5 weeks) was 111.2-132.6 mg/dL in the control group, not significantly different from others; After diabetes induction, however, the contents were 212.8 mg/dL in the control group, 140.0-144.0 mg/dL in the H-l and H-2 groups, which showed significant difference. Urine glucose contents of H-2 group before and after diabetes induction were lower than those of control and H-l groups. There was no significant difference in the content of neutral lipid between each groups. Total cholesterol contents were 101.6 mg/dL in the control group, 56.∼64.0 mg/dL in the hemicellulose groups. HDL-cholesterol content and atherogenic index of hemicellulose groups were lower than those of control group, respectively. In conclusion, the hemicellulose extracted from Shiitake mushroom represented improving and preventing effects for diabetes.

Objective: Combination of two stressors on alteration of mineral footprints in animals needs due attention to meet maximum production and welfare, particularly in grazing sheep. This study tested whether ewes (Ovis aries) exposed to water deprivation and thermal-humidity stressors had altered mineral footprints in their wool, serum, urine, and feces. Methods: Nine ewes (age = 3 years; mean body weight = 41±3.5 kg) were divided among a control group with free access to water, and treatment groups with water deprivation lasting either 2 h (2hWD) or 3 h (3hWD) after feeding. Using a 3×3 Latin square design, animals were assigned to treatment groups for three sampling periods of 21 days each (n = 9). Blood was collected by jugular venipuncture. Wool was collected at the end of periods 2 and 3. Metabolic crates designed with metal grated floors were used for urine and feces collection. We measured sodium (Na), magnesium (Mg), phosphorus (P), chloride (Cl), calcium (Ca), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn). Results: The wool mineral levels did not differ between the treatment groups, although K was marginally lower (p = 0.10) in the 2hWD group. The serum and urine mineral levels did not differ between the treatments (p>0.05). Fecal K was significantly lower in the 2hWD group than in the other groups (p≤0.05). Conclusion: In conclusion, water deprivation and thermal-humidity exposure altered the excretion of K, but not of other minerals, in the wool, urine, feces, or serum of ewes. Thus, no additional mineral supplementation is needed for water deprived ewes during thermalhumidity exposure.
