The effects of ketamine anesthesia on both hematological and serum biochemical variables were investigated in 19 male and 15 female cynomolgus monkeys. Blood samples were obtained from the cephalic vein within 30 minutes of an intramuscular injection of ketamine hydrochloride (10 mg/kg). Ketamine anesthesia caused a reduction in leukocyte counts and a significant reduction in lymphocytes percentages. Ketamine anesthesia also increased the serum activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine phosphokinase (CPK), but reduced the serum concentrations of glucose, inorganic phosphate, sodium and potassium. The alterations of hematological and serum biochemical values will be discussed. These alterations should be considered when designing studies for and interpreting data from cynomolgus monkeys. 相似文献

Background Non-human primates are frequently sedated to permit handling that can alter physiological values. The purpose of this study was to identify the effects of daily serial sedation using ketamine (K) or ketamine combined with medetomidine (KM). We hypothesized KM would reduce observed effects of repeated sedation.
Methods Eight rhesus macaques were anesthetized for three consecutive days. Physiological data were recorded daily at 5-minute intervals. Time intervals from injection to ataxia, recumbency, first movement and recovery were recorded. Depth of anesthesia was evaluated.
Results Data showed an 11.7% increased heart rate at 5 minutes between the first and third day of injection with K and 17.9% with KM. Time from injection to ataxia increased 13.7% with K and 14.3% with KM. Time to recumbency increased 34.7% with K and 37.1% with KM.
Conclusion These findings demonstrate repeated anesthesia with ketamine can initiate changes suggesting a tolerance effect. 相似文献

Hematologic, protein electrophoresis, serum biochemistry, and cholinesterase values were determined in 36 free-living black stork nestlings (Ciconia nigra) between 25 and 53 days of age in order to establish normal reference values for this population. The following values were evaluated: white blood cell counts, red blood cell counts, packed cell volume, hemoglobin, heterophils, lymphocytes, monocytes, eosinophils, prealbumin, albumin, alpha-globulin, beta-globulin, gamma-globulin, total protein, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatine kinase, calcium, phosphorus, iron, cholesterol, glucose, triglycerides, uric acid, urea, creatinine, total solids, bile acids, and butyrylcholinesterase. Sex-dependent differences were observed in hemoglobin, prealbumin, albumin, gamma-globulin, total protein, alkaline phosphatase, and triglycerides. Packed cell volume, butyrylcholinesterase, aspartate aminotransferase, creatine kinase, and creatinine increased with age, whereas albumin, mean cell volume, calcium, phosphorus, cholesterol, and total solids decreased with age. These hematologic and serum biochemistry values can be used as reference ranges in free-living black stork nestlings. 相似文献

Local myotoxicity of ketamine hydrochloride in the marmoset 总被引:1,自引:0,他引:1
An investigation of raised plasma aspartate aminotransferase (AST) in marmosets after intramuscular ketamine injection suggested a local myotoxicity. This was confirmed by a range of histopathological findings from myofibrillar striation loss to necrosis. In addition to the elevations in AST levels, creatine kinase and the lactate dehydrogenase-5 isoenzyme levels were elevated. It was further demonstrated that, although the physical properties of the injectable solution (pH, osmolality) and to a lesser extent the injection procedure itself caused slight changes in plasma enzyme levels, the ketamine was predominantly responsible for the lesion. No hepatic interactions were seen. This effect should be taken into consideration when this anaesthetic is used in the marmoset if the primary objectives of the experiment entail routine blood analyses. 相似文献

The effects of ketamine anesthesia (15 mg/kg body weight) on hematological and serum biochemical values were examined in six female cynomolgus monkeys (Macaca fascicularis) who were born in the wild. As control, another six female cynomolgus monkeys of the same origin were injected with physiological saline. The white blood cell count, total protein concentration, albumin concentration and calcium concentration decreased after the injection of ketamine, whereas the red blood cell count, hematocrit value, hemoglobin concentration, total cholesterol concentration, free cholesterol concentration, triglyceride concentration, transaminase activities (GOT, GPT) and alkaline phosphatase activity were not affected. A transient increase of the serum glucose level was observed within 10 minutes after ketamine injection. The relationship between these effects of ketamine anesthesia and serum cortisol levels measured by radioimmunoassay was discussed. 相似文献

We evaluated the effects of koumiss on some hematological and biochemical characteristics of persons who exercise. Eighteen sedentary males were assigned to three equal groups: koumiss (K), koumiss + exercise (KE) and exercise alone (E). Leukocytes (WBC), differential leucocyte count, erythrocytes (RBC), hemoglobin (HGB), hematocrit (HCT), platelet (PLT), glucose, total cholesterol, triglycerides, high density lipoprotein (HDL), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were assessed In blood samples. By the end of the study, triglycerides (TG) and cholesterol levels tended to decrease in all groups, but the decrease was significant only at day 15 for the KE group. HDL tended to be increased in all groups at day 15, but the increase was significant only in the KE group. We found that koumiss had beneficial effects on some hematological and biochemical characteristics. 相似文献

Serum biochemical values were determined in blood samples collected from 48 shot fallow deer from the Brijuni islands and 45 sedated fallow deer (Dama dama L.) from hunting grounds in the continental part of Croatia. The parameters were compared with regard to age, sex and habitat. Statistically significant differences were found for serum total protein concentration, alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase activity between young and adult island deer, as well as for total protein, triacylglyceride, cholesterol concentration and alkaline phosphatase activity between young and adult continental deer. In young animals, island males had higher albumin concentrations, while continental males had higher alkaline phosphatase values than females. In adult animals, island males had a higher blood urea nitrogen concentration, while continental males had higher albumin and cholesterol concentrations, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and creatine kinase activities. In this group, males exhibited lower bilirubin and triacylglyceride concentrations than females. Our results indicate that besides age, sex and sampling method, nutritional and environmental factors should be considered when evaluating serum biochemical parameters of fallow deer 相似文献

Cypermethrin is a highly active type II pyrethroid that is widely used to control harmful insects. The present study was conducted to investigate the possible effects of the sublethal concentration of cypermethrin (0.05 μL/L) on the biometric, hematological, and biochemical parameters of Van fish (Alburnus tarichi Guldenstadt 1814) for 24, 48, 72, and 96 h. Behavioral and physiological changes were observed in the fish treated with cypermethrin. Hematological parameters revealed a significant decrease in the erythrocyte (RBC), hemoglobin (Hb), and hematocrit (Hct) values (p ≤ .05). Serum enzymes, aspartate aminotransferase (AST, EC 2.6.1.1), alanine aminotransferase (ALT, EC 2.6.1.2), and lactate dehydrogenase (LDH, EC 1.1.1.27) activities and serum cortisol level were significantly increased (p ≤ .05). The results showed that changes in the biometric, biochemical, and hematological values of the Van fish exposed to cypermethrin can be used as biomarkers for monitoring toxicity. 相似文献

This study was undertaken to investigate the hematological and biochemical changes in experimentally infected goats with Besnoitia caprae from the time of infection till 360 days post-infection (PI). Six male goats were inoculated subcutaneously with 13 × 10(7) bradyzoites of B. caprae, and blood samples were collected from the jugular vein. The total erythrocyte and total leukocyte counts, hematocrit value, and differential leukocyte counts were determined. Serum biochemical analysis, including the total protein, albumin, total globulin, cholesterol, triglyceride, chloride, testosterone, calcium (Ca(2+)), inorganic phosphorus, sodium (Na(+)), potassium (K(+)), iron (Fe(2+)), glucose, serum amyloid A (SAA), haptoglobin (Hp), fibrinogen, ceruloplasmin, aspartate aminotransferase, alanine aminotransferase, creatine kinase, lactate dehydrogenase, and alkaline phosphatase, was undertaken. Skin biopsy from the limbs were collected at weekly intervals and histologically examined for Besnoitia cysts. Cysts were present in the skin biopsies of the leg of the infected goats from day 28 PI. There were variations in hematological analyses, but no significant difference was seen. From day 30 to 360 PI, results showed that SAA, Hp, fibrinogen, and ceruloplasmin concentrations increased, whereas testosterone concentrations decreased. Infected goats exhibited decrease of albumin and increase of serum total protein and globulin concentrations. By contrast, there were no significant differences in the remained analyses concentrations. 相似文献

Ketamine hydrochloride is frequently administered to non-human primates as a means of chemical restraint. This procedure can be a frequent source of stress to monkeys at research facilities, impacting animal health, well-being and research quality. This study was designed to measure ketamine's effect on daily food intake, a parameter that reflects and influences animal well-being and directly impacts research studies. On five occasions, baseline daily food intake was compared to daily food intake occurring 24, 48, 72, 96, and 120 h after an intramuscular injection of 10 mg/kg ketamine in male African green monkeys (AGMs) (Cercopithecus aethiops) and male and female rhesus macaques (Macaca mulatta). AGMs and female rhesus macaques had significantly reduced daily food intake during the first 4 days after receiving ketamine. The AGMs continued to display significantly reduced daily food intake on the fifth day after ketamine. The male rhesus macagues showed a trend toward reduced daily food intake, greatest during the first 2 days and remaining less than baseline intake through the fifth day following ketamine. The degree of observed food intake reduction was most severe at the 24 h (mean percent intake reduction: AGMs: 57%; rhesus males: 48%; rhesus females: 40%) and 48 h time points (AGMs: 24%; rhesus males: 14%; rhesus females: 13%). A subset of the AGMs that did not receive ketamine, but observed other animals in the room receive ketamine, showed reduced food intake at 24 and 48 h after ketamine, though not to the degree associated with ketamine administration. These results indicate that ketamine anesthesia is associated with a prolonged reduction in daily food intake in AGMs and rhesus macaques. Frequent use of ketamine in non-human primates may have a significant impact on animal health and well-being, and alternatives to its use warrant consideration. 相似文献

In this study, to identify mercury (Hg) toxicity and whether selenium (Se) has any role in alleviation of this toxicity, it was investigated the changes in hematological and serum biochemical parameters of Oreochromis niloticus. Fish were exposed to 0.01 and 0.1 mg/L Hg and 0.01 mg/L Hg + 0.1 mg/L Se and 0.1 mg/L Hg + 1.0 mg/L Se for 7 and 14 days. The exposure of O. niloticus to Hg alone resulted in decreases in red blood cell, white blood cell, hemoglobin, hematocrit values, and cholinesterase activity while it increased in alanine aminotransferase and aspartate aminotransferase activities and cortisol and glucose levels. Se, in combination with Hg, partially or totally caused an alleviation for the toxic effect of Hg on the above mentioned hematological and biochemical parameters. The results of our study showed that Se has a protective effect against toxicity induced by Hg. 相似文献

Hematologic and serum chemistry reference intervals were determined from 33 wild caught Eurasian otters (Lutra lutra lutra) between November 1995 and May 1998 during a reintroduction project. Blood was obtained by jugular venipuncture after administration of ketamine and medetomidine. The mean, standard deviation, and range for 19 hematology parameters and 28 serum chemistry values are presented. There were no significant differences between sexes in most analytes. The results are in agreement with those reported previously for Eurasian otters with the exception of higher leukocyte and neutrophil counts, lower eosinophil and lymphocyte counts and higher activities for aspartate aminotransferase and creatine kinase. The Eurasian otters have lower erythrocyte counts but higher mean corpuscular volume and mean corpuscular hemoglobin values than the river otter (Lutra canadensis) in North America. 相似文献

To identify an anesthetic regimen that produces more complete relaxation and analgesia than ketamine hydrochloride (Ketaset®) alone, a combination of ketamine (15 mg/kg body weight) and the hypnotic xylazine (Rompun®, 0.33 mg/kg) was evaluated. Since the desired experimental application required that the anesthetic not interfere with normal hormonal events during the menstrual cycle, this combination administered on day 6 of the cycle was tested to determine whether hormonal surges, incidence of ovulation, or cycle length would be altered relative to the use of ketamine alone. In five of six animals, ketamine plus xylazine had no effect on the occurrence of timely surges of estrogen, luteinizing hormone (LH), or follicle-stimulating hormone (FSH), or on ovulation as determined by the presence of a corpus luteum at laparoscopy and normal serum concentrations of progesterone. There were no significant differences between the cycle during treatment and previous cycles in the same animal for length of the menstrual cycle (26.0 ± 2.3 [5] days; X? ± S.D. [n] or luteal phase (13.4 ± 2.4 [5] days). Likewise, these values did not differ from those of ten control monkeys treated with ketumine only on day 5 or 6 of the cycle (incidence of ovulation, 10/10; cycle length, 27.9 ± 1.8 [10]; luteal phase length, 15.1 ± 1.4 [10], P > 0.05). Patterns of circulating progesterone were not altered by the addition of xylazine anesthesia. These findings indicate that xylazine, given in the midfollicular phase, did not alter ovulatory events or menstrual cycle characteristics in rhesus monkeys. Ketamine plus xylazine apparently provides anesthesia appropriate for laparoscopy. 相似文献

The following 10 enzymes were assayed in 187 amniotic fluid and maternal serum samples at 15-42 weeks of gestation: alkaline phosphatase, heat-stable alkaline phosphatase (only in amniotic fluid), acid phosphatase, alanine aminotransferase, aspartate aminotransferase, alpha-amylase, gamma-glutamyltransferase, creatine kinase, lactate dehydrogenase, and lysozyme. The normal reference ranges are reported for amniotic fluid and maternal serum enzymes, together with the abnormal values accompanying neural tube defects and EPH-gestosis. The determination of gamma-glutamyltransferase, heat-stable alkaline phosphatase and creatine kinase was found to be of appreciable diagnostic significance in clinical practice. 相似文献

Physiological stress responses in big gamefish after capture: observations on plasma chemistry and blood factors 总被引:4,自引:0,他引:4

The plasma electrolytes, Na+, K+, Ca2+, Cl- and osmolarities had high values in capture-stressed big gamefish. Blood metabolites measured after stress showed glucose and lactate elevations. The activity of the plasma enzymes alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, creatine kinase and lactate dehydrogenase suggested tissue disruptions following severe capture stress. Haematocrit values and methaemoglobin were high in capture-stressed gamefish. The plasma chemistry of resting and capture-stressed snapper (Chrysophrys auratus) was studied for comparison. Specific differences in plasma biochemistry appeared to be the result of different strategies of fish behaviour during capture. 相似文献

The effect of cold exposure on the sympathoadrenal system in primates was studied with and without ketamine anesthesia in eight adult rhesus monkeys. Each monkey was placed in a primate chair at a thermoneutral temperature (25 degrees C) for 1 h (control) followed by cold exposure (12 degrees C) for 3 h or placed in a circulating water bath (28 degrees C) to induce a decrease in core temperature (Tre) to 35 and 33 degrees C. Plasma catecholamines were analyzed by high-pressure liquid chromatography with electrochemical detection (60-65% recovery, coefficient of variation = 15%). The 3-h cold exposure was associated with a 175% increase above control levels of norepinephrine (NE) and a 100% increase in epinephrine (E). Decreases were evident in Tre (0.5 degree C), mean skin temperature (Tsk, 5.5 degrees C), and mean body temperature (Tb, 2.0 degrees C). Continuous infusion of ketamine (0.65 mg . kg-1 . min-1) resulted in no change in the plasma levels of NE and E from the control levels. Tre, Tsk, and Tb all showed greater declines with the addition of ketamine infusion to the cold exposure. Water exposure (28 degrees C) under ketamine anesthesia resulted in a drop in Tre to 33 degrees C within 1 h. Plasma levels of NE and E were unchanged from control values at Tre of 35 and 33 degrees C. The data suggest that the administration of ketamine abolished both the thermoregulatory response and the catecholamine response to acute cold exposure. 相似文献

Serial physiological responses were examined for 150 min from captive collared peccaries during immobilization with ketamine hydrochloride. Rectal temperatures decreased significantly (P less than 0.01) during anesthesia. Serum concentrations of total proteins, albumin, cholesterol, alanine aminotransferase, and calcium declined significantly (P less than 0.05) during the first 45 min post-immobilization before stabilizing. Concentrations of lactate dehydrogenase and alkaline phosphatase in sera showed similar but nonsignificant (P greater than 0.05) trends. Inorganic phosphorus and aspartate aminotransferase concentrations increased significantly (P less than 0.05) throughout the trial. Concentrations of serum glucose and glucocorticoid during the immobilization period were highly variable between individuals. Serum electrolytes, urea nitrogen, creatinine, gammaglutamyl transferase and progesterone were not significantly (P greater than 0.05) affected by immobilization. Elevations in serum testosterone were noted. Results indicated appropriate sampling times relative to immobilization for assay of particular serum biochemicals and steroid hormones during investigations of the physiology of the collared peccary. 相似文献

To establish baseline hematologic and plasma biochemistry values in free-ranging Humboldt penguins (Spheniscus humboldti), heparinized blood samples were collected from 51 apparently healthy, adult Humboldt penguins residing at two colonies off the Chilean coast. Thirty samples were collected in April, 1992, from penguins inhabiting the Ex-islote de los Pájaros Niños in Algarrobo, Chile. In September, 1992, 21 samples were collected from birds inhabiting Isla de Cachagua, Chile. Hematologic values measured include packed cell volume, leucocyte count, leucocyte differential, and the presence of blood parasites. Plasma biochemistry values measured include glucose, blood urea nitrogen, creatinine, uric acid, calcium, inorganic phosphorous, sodium, potassium, chloride, total protein, albumin, globulin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, and creatine kinase. Only the mean values for chloride and for the number of eosinophils differed significantly between the two sample groups. No blood parasites were seen. © 1995 Wiley-Liss, Inc. 相似文献

Between October 2002 and September 2004, 70 free-ranging Spanish ibex (Capra pyrenaica) were captured in Catalonia, northeastern Spain, using two different physical methods, drive-net (n=26) and box-trap (n=44). Blood samples were taken to determine 20 hematologic and 23 biochemical variables. Values obtained fell within already published reference intervals, with the following exceptions: higher values for red blood cells (RBC), packed cell volume (PCV), white blood cells (WBC), eosinophil count, triglyceride concentration, creatine kinase (CK; in box-trap), chloride, sodium, alpha-1, alpha-2, and gamma electrophoretic fractions of serum proteins; and lower values for hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), urea concentration, CK (in drive-net), albumin, and albumin:globulins ratio (A:G). Published values for aspartate aminotransferase (AST) concentration are both higher and lower than observed in this study. In our study, monocyte and eosinophil counts, as well as triglyceride and potassium concentrations, were lower in animals captured via box-trap than those captured via drive-net. Conversely, MCHC, neutrophil count, total bilirubin concentration, urea, and AST were higher in animals captured via box-trap. Hematologic and biochemical values obtained from Spanish ibexes show that the drive-net is a newer, less-stressful method of capture than the box-trap. 相似文献
