Physiologic measures of nonhuman primates during physical restraint and chemical immobilization.

The arterial acid-base balance and other selected physiologic measures of physically restrained and chemically immobilized nonhuman primates from the families Callithricidae, Cebidae, Cercopithecidae, and Pongidae were compared. The physically restrained primates had significantly lower pH, pCO2, and base excess values, but they had significantly higher pO2 values, rectal temperatures, and pulse and respiration rates. Of 56 physically restrained primates, 30 (54%) experienced severe metabolic acidosis, with pH values less than 7.2; 15 (27% of total) had pH values less than 7.1. Two types of behavior were observed during the physical restraint of golden marmosets. Some of the marmosets were excited during restraint, with a great deal of struggling and vocalizing. The other marmosets were quiet and calm, with minimal struggling. The excited group had significantly lower pH, pCO2, and base excess values, but significantly higher pO2 values, rectal temperatures, and pulse and respiration rates. Primates immobilized with ketamine or tiletaminezolazepam had a near normal acid-base balance and were handled more easily than the physically restrained animals.  相似文献

Dermatophilosis in Australian bearded lizards.     

R J Montali  E E Smith  M Davenport  M Bush 《Journal of the American Veterinary Medical Association》1975,167(7):553-555

Dermatophilosis (Dermatophilus congolensis) was diagnosed in 3 Australian bearded lizards. Each lizard died of causes associated with stress and poor adaptability, although the lesions appeared to be regressing at the time of death.  相似文献

Anaesthesia of roan antelope (Hippotragus equinus) with a combination of A3080, medetomidine and ketamine     

Citino SB  Bush M  Grobler D  Lance W 《Journal of the South African Veterinary Association》2001,72(1):29-32

A dose range was determined for anaesthesia of 20 recently boma-captured roan antelope (Hippotragus equinus) with the synthetic opiate A3080 combined with medetomidine and ketamine. A dose of 10-30 micro/kg A3080 (x = 20+/-8 microg/kg) combined with 5-21 microg/kg medetomidine (x = 13+/-7 microg/kg) plus 0.29-1.11 mg/kg ketamine (x = 0.71+/-0.24 mg/kg) was found to be safe and effective for the field conditions in this study. The anaesthesia produced by this drug combination was predictable and characterised by a short induction time, good muscle relaxation, and acceptable physiological parameters for anaesthesia periods ranging from 49-103 min (x = 64+/-19 min). The wide range (3-4-fold) of doses with acceptable results is also an indication that this drug combination has a wide margin of safety in roan antelope, making it desirable for field use. When 2 dose levels (2-3-fold dif ference) were retrospectively evaluated, no statistical difference was found in induction times, and no observable clinical differences in the anaesthetic episodes were seen. Based on this study, the recommended dose range in roan antelope for this combination is 10-13 microg/kg A3080, 5-6 microg/kg medetomidine and 0.3-0.6 mg/kg ketamine. The anaesthesia produced by this combination was rapidly and completely reversed by i.m. or i.v. injections of naltrexone at 30 times the A3080 dose (x = 0.60+/-0.25 mg/kg) and atipamezole at 3 times the medetomidine dose (x = 38+/-20 microg/kg). No residual effects from ketamine were noted following reversal of A3080 and medetomidine. No mortality was associated with this protocol.  相似文献   

Anaesthesia of gemsbok (Oryx gazella) with a combination of A3080, medetomidine and ketamine     

Grobler D  Bush M  Jessup D  Lance W 《Journal of the South African Veterinary Association》2001,72(2):81-83

An effective anaesthesia protocol was developed for adult free-ranging gemsbok (Oryx gazella) using a combination of A3080, medetomidine and ketamine. A short induction time; good muscle relaxation, adequate oxygenation and stable heart rate and respiration rate characterised this anaesthetic regime. Equal doses of A3080 and medetomidine (22-45 microg/kg) plus 200 mg of ketamine were administered to each animal. The anaesthesia was rapidly and completely reversed by intramuscular naltrexone at a dose of X = 0.9 +/- 0.2 mg/kg and atipamezole at a dose X +/- 90 +/- 20 microg/kg. No mortality or morbidity occurred with this protocol.  相似文献   

白肋烟晾制过程中硝酸还原酶活动的变化   总被引：4，自引：0，他引：4

 烟叶采收晾制后,体内硝酸还原酶活动剧烈下降,晾制后4d,叶肉内该酶活性即下降至0,晾制后两周主脉内此酶活性下降至0.且两种电子供体间无显着差异.烟叶体外硝酸还原酶活动晾制开始时很低,晾制3周后增加.整个晾制过程中叶肉、主脉硝酸盐含量均无显着变化.晾制后两周主脉亚硝酸盐含量很低,但是晾制后3周开始逐渐增加,叶肉亚硝酸盐在整个晾制过程中无变化.晾制后3周,主脉亚硝酸盐含量增加,与体外硝酸还原酶活动相关,这可能是微生物的酶起作用.  相似文献

Numerical Simulation of the Cretaceous Tethys Circumglobal Current     

ABG Bush 《Science (New York, N.Y.)》1997,275(5301):807-810

Certain paleobiogeographical reconstructions of ocean currents during the Cretaceous (about 144 to 65 million years ago) suggest that a circumglobal tropical current flowed westward through the continental configuration of that time. Although some numerical climate models failed in initial attempts to simulate this current, simulations with a coupled atmosphere-ocean model with relatively high spatial resolution and a late Cretaceous continental distribution show that a circumglobal current is a robust feature even though local surface currents in the Tethys Seaway reverse during the south Eurasian monsoon months.  相似文献   

Transmission of HIV in Belle Glade, Florida: lessons for other communities in the United States   总被引：4，自引：0，他引：4

The high cumulative incidence of AIDS and the large percentage of AIDS patients with no identified risks in Belle Glade, Florida, were evaluated through case interviews and neighborhood-based seroepidemiologic studies. It was found that of 93 AIDS patients reported between July 1982 and 1 August 1987, 34 could be directly linked to at least one other AIDS patient or to a person with AIDS-related complex by sexual contact, sharing of needles during intravenous drug abuse (or both), or perinatal exposure; of 877 randomly selected adults, 28 had antibodies to HIV; no person over age 60 and none of 138 children aged 2 to 10 years had antibodies to HIV; no clustering of infected persons within households occurred, except in sex partners; and HIV-seropositive adults were more likely than HIV-seronegative adults to be from Haiti, have a lower income, report sex with intravenous drug abusers, and have a history of previous treatment for sexually transmitted diseases. The presence of antibodies to five arboviruses prevalent in South Florida or the Caribbean did not correlate significantly with HIV infection. The high cumulative rate of AIDS in Belle Glade appears to be the result of HIV transmission through sexual contact and intravenous drug abuse; the evidence does not suggest transmission of HIV through insects.  相似文献
