The effects of intravenous infusion of hypotonic lactated Ringer's (LR: n=14) on plasma volume and venous blood gases were compared to those of hypotonic Ringer's solutions (RS: n=7) in diarrheic Japanese Black breed calves with metabolic acidosis. Venous blood samples were collected immediately before and after, and at 24 hr after the fluid infusion therapy. The LR and RS infusions increased relative plasma volume to 147.1 +/- 25.5% and 134.2 +/- 18.6%, respectively, just after the fluid therapy. The LR infusion induced an increase in the BE value (+5.1 +/- 4.8 mM) at 24 hr compared to that of RS. LR infusion should be explored as a treatment for dehydration and moderate metabolic acidemia caused by naturally occurring diarrhea in calves. 相似文献

After intravenous (i.v.) infusion of various volumes of 1.35%-isotonic sodium bicarbonate solution (ISB), acid-base equilibrium, blood pressure, plasma volume and biochemical parameters in healthy Holstein calves were studied. Four calves each were randomly assigned to the low-dose (LD; i.v. infusion of 5 ml/kg ISB), middle-dose (MD; i.v. infusion of 10 ml/kg ISB) and the high-dose groups (HD; i.v. infusion of 15 ml/kg ISB). Administration volumes of ISB in the LD, MD and HD groups were decided based on the first half volumes of 5, 10 and 15 mEq of base requirement by the acceptable equation. Systemic, pulmonary artery and central venous pressures, cardiac output and plasma osmotic pressure were not changed by ISB infusion and remained constant throughout the experiment for all groups. There was good correlation (r(2) = 0.950) between relative changes in base excess and infused volume of bicarbonate (y=2.491x). The coefficient of distribution for bicarbonate ions was calculated to be 0.401 (=1/2.491). Therefore, it is suggested that a value of 0.4 would be most appropriate when calculating the base requirements in calves. Therefore, the first half volumes of ISB correcting base deficits of 5, 10 and 15 mEq in calves were estimated to be 6, 12 and 18 ml/kg, respectively. On the basis of the findings in this study, ISB may be used to correct metabolic acidosis without altering the plasma osmotic pressure, hemodynamic status and respiratory function in the calves. 相似文献

The effect of 1.35% isotonic sodium bicarbonate solution (ISB) administered intravenously on acid-base equilibrium was examined in 18 acidemic Japanese black beef calves with spontaneous diarrhea. The infusion volumes of ISB were decided based on the first half volumes of base needed. In 72.2% (13/18) of calves, improvement of acidemia was detected. There was good correlation (r=0.693, p<0.01) between infused volume of ISB and changes in base excess (y=1.097x + 4.762). Infusion volumes of ISB were 7.5, 10.2, 12.9 and 15.7 ml/kg, respectively, enough to correcting the first half of 5, 10, 15 and 20 mEq/l of base deficit in acidemic calves. Our finding suggested that ISB could be used to correct metabolic acidosis without altering electrolyte concentrations in calves. 相似文献

We investigated the optimal timing of simeconazole (RS-2-(4-fluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-trimethylsilylpropan-2-ol) application for controlling rice kernel smut in field trials in Miyagi Prefecture,
Japan, using formulations of simeconazole (1.5% granules). The field tests revealed that a submerged application of simeconazole
granules (450–600 g ai/ha) at 1–5 weeks before heading was highly effective against kernel smut, with treatments 1–2 weeks
before heading being the most effective. Submerged application of the fungicide at 2–5 weeks before heading was also highly
effective against false smut, with treatment 3 weeks before heading being the most effective. These periods overlap the timing
for optimal application of simeconazole to control rice sheath blight and ear blight. Consequently, we concluded that treatment
with simeconazole 2–3 weeks before heading can be a useful tool for controlling all four diseases. 相似文献

The relationship between soil air volume and CH4 consumption in brown forest soils was investigated. The CH4 consumption was negatively affected when the soil air volume decreased in experiments carried out bothin situ and in the laboratory. A strong dependence of the CH4 consumption on the soil air volume was found in the laboratory experiment. These results indicate the possibility that the
soil air volume is the primary rate-limiting factor for the CH4 consumption in forest soil. Thus our work suggests that the other factors by which CH4 consumption might be affected should be examined under the same air volume condition in the soil. To obtain accurate data,
we need to be careful not to change the air volume by trampling or disturbing during the measurement of the natural methane
fluxin situ. 相似文献

The pharmacological effects of the anesthetic alfaxalone were evaluated after
intramuscular (IM) administration to 6 healthy beagle dogs. The dogs received three IM
doses each of alfaxalone at increasing dose rates of 5 mg/kg (IM5), 7.5 mg/kg (IM7.5) and
10 mg/kg (IM10) every other day. Anesthetic effect was subjectively
evaluated by using an ordinal scoring system to determine the degree of neuro-depression
and the quality of anesthetic induction and recovery from anesthesia. Cardiorespiratory
variables were measured using noninvasive methods. Alfaxalone administered IM produced
dose-dependent neuro-depression and lateral recumbency (i.e., 36 ± 28 min, 87 ± 26 min and
115 ± 29 min after the IM5, IM7.5 and IM10 treatments, respectively). The endotracheal
tube was tolerated in all dogs for 46 ± 20 and 58 ± 21 min after the IM7.5 and IM10
treatments, respectively. It was not possible to place endotracheal tubes in 5 of the
6 dogs after the IM5 treatment. Most cardiorespiratory variables remained
within clinically acceptable ranges, but hypoxemia was observed by pulse oximetry for 5 to
10 min in 2 dogs receiving the IM10 treatment. Dose-dependent decreases in rectal
temperature, respiratory rate and arterial blood pressure also occurred. The quality of
recovery was considered satisfactory in all dogs receiving each treatment; all the dog
exhibited transient muscular tremors and staggering gait. In conclusion, IM alfaxalone
produced a dose-dependent anesthetic effect with relatively mild cardiorespiratory
depression in dogs. However, hypoxemia may occur at higher IM doses of alfaxalone. 相似文献

To determine the reference level of central venous oxygen saturation (ScvO2)
and clinical efficacy of central venous blood gas analysis, partial pressures of oxygen
and carbon dioxide, pH, oxygen saturation, base excess (B.E.) and HCO3
concentration were compared between simultaneously obtained central venous and arterial
blood samples from conscious healthy 6 dogs and 5 cats. Comparisons between arteriovenous
samples were performed by a paired t-test and Bland-Altman analysis.
Between arteriovenous samples, B.E. showed good agreement, but there were significant
differences in other parameters in the dogs, and no good agreement was detected in cats.
The ScvO2 in dogs and cats were 82.3 ± 3.5 and 62.4 ± 13.5%, respectively.
Central venous blood gas analysis is indispensable, especially in cats. 相似文献
