ABSTRACT The aim of this study was to determine the anesthetic efficacy of the essential oils (EOs) of Aniba rosaeodora (EOAR) and Aniba parviflora (EOAP) and one of their main compounds, linalool, in two forms: synthetic and extracted from EOAR (linalool-AR) in tambaqui (Colossoma macropomum). In the first experiment, the anesthetic induction and recovery of juveniles exposed to 25- 200 µL L-1 of EOAR or 50- 300 µL L-1 of EOAP or synthetic linalool or linalool-AR was evaluated. The second experiment observed the behavioral effects of long-term exposure (12h) of these EOs and linalools (5 and 10 µL L-1). Fish exposed to 50-200 µL L-1 of EOAR and 100-300 µL L-1 of EOAP and both linalools reached deep anesthesia between 1-10 min. Induction time for all...

This study analyzed the chemical composition and anesthetic potential of essential oil (EO) of Nectandra megapotamica in fat snook (Centropomus parallelus). For the extraction of EO by hydrodistillation, leaves were separated in young (EO-Y) or old (EO-O), and the chemical composition of the EOs was determined by CG-MS. The anesthetic potential was assessed by the evaluation of induction and recovery time of anesthesia and stress response from anesthesia and transport. Three experiments were carried out: i) four different concentrations of each EO were tested to evaluate anesthesia induction and recovery time; ii) two concentrations of EO-O were tested for the evaluation of its effects on stress parameters (glucose, lactate, and Na+ and K+ plasma levels)...

Provedor de dados: 42
Autores: NETTO,JOSÉ D. LIMMA; OLIVEIRA,REBECA S.M.; COPATTI,CARLOS EDUARDO.
ABSTRACT This study aimed to verify the sedative and anaesthetic effect of the essential oils of basil (Ocimum basilicum) (EOOB) and lemongrass (Cymbopogum flexuosus) (EOCF) in Nile tilapia juveniles. The fish were transferred to aquaria containing different concentrations of each essential oil: 10, 25, 50, 100, 200, 400 and 600 μL L-1. The time of sedation ranged from 7 to 31 seconds and the recommended concentration was 10 or 25 μL L-1 for both essential oils. The best times for anaesthesia and recovery were found for the concentrations of 400 μL L-1 for EOOB (135.2 and 199.1 seconds, respectively) and 600 μL L-1 for EOCF (327.1 and 374.8 seconds, respectively). In conclusion, we recommend the use of EOOB and EOCF for the sedation and anaesthesia of Nile...

Comparative study of the sedative and antinociceptive effects of levomepromazine, azaperone and midazolam in laboratory animals
Provedor de dados: 45
Autores: Mataqueiro,M.I.; D’Angelis,F.H.F.; De-Caroli-Neto,A.; Rossi,C.A.; Queiroz-Neto,A.
The sedative and antinociceptive effects of levomepromazine, azaperone and midazolam were studied in rats and mice using three behavior evaluation methods. Both exploratory behavior and spontaneous locomotor activity were significantly diminished in a spontaneous locomotor activity test in open field when using levomepromazine and azaperone. However, the azaperone effects were short lived in comparison to levomepromazine effects. Midazolam caused reduction in exploratory activity with no effect in spontaneous locomotion. When assessing the antinociceptive effect in the tail flick reflex latency test after infliction of a pain stimulus in rats, tested drugs did not show any antinociceptive effect. The drugs studied were able to abolish the writhing reflex...

Sedative and antinociceptive effects of romifidine and xylazine in Thoroughbred mares
Provedor de dados: 45
Autores: Christovão,F.G.; Zamur,G.; Mataqueiro,M.I.; Queiroz-Neto,A.
The sedative and antinociceptive effects of romifidine (0.1mg/kg) and of xylazine (1.0mg/kg) on Thoroughbred mares were studied. Sedation was evaluated by quantifying spontaneous locomotor activity (SLA) and head height (HH) in animals placed in automated individual behaviour stalls. Antinociception was determined utilizing a heat irradiation lamp recording the latency time for the hoof withdrawal reflex (HWRL) and the latency time for the skin twitch reflex (STRL) in a randomised block design with 10 replicates. Comparison of the sedative effects of romifidine and of xylazine on SLA showed a faster effect for xylazine. Regarding the sedative effect of the substances based on HH, romifidine caused a longer-lasting effect. Romifidine caused an increase in...

Comparison of behavioral and clinical effects of intravenous amitraz or romifidine administration in horses
Provedor de dados: 45
Autores: Mendes,M.C.; Reis,R.G.; Valadão,C.A.A.; Marques,J.A.
Clinical and behavioral effects of intravenous injection of romifidine (60mcg/kg) or amitraz (0.4mg/kg) were compared in six horses, over 120 min. Romifidine caused head ptosis (HP), reduced respiratory rate (RR) and ileo-cecal sphincter activity (IC) until 120 minutes; produced posture changes (PC) until 90 minutes, upper eyelid drop (ED) and sedation (SD) until 60 minutes, intestinal motion (IM) reduction and lower lip drop (LD) until 45 minutes. Amitraz reduced heart rate (HR), RR, IM and IC, and promoted HP, ED, LD, penis drop (PD) and sedation with posture changes until 120min. At 90min amitraz produced HP and ED more intensively than romifidine. The LD was similar between 45 and 60 minutes. Romifidine produced intense sedation at 10min while amitraz...

Effects of sedation during upper gastrointestinal endoscopy on endocrine response and cardiorespiratory function
Provedor de dados: 56
Autores: Yetkin,G.; Oba,S.; Uludag,M.; Paksoy,I.; Akgün,I.; Eren,N.
Upper gastrointestinal endoscopy is often accompanied by tachycardia which is known to be an important pathogenic factor in the development of myocardial ischemia. The pathogenesis of tachycardia is unknown but the condition is thought to be due to the endocrine response to endoscopy. The purpose of the present study was to investigate the effects of sedation on the endocrine response and cardiorespiratory function. Forty patients scheduled for diagnostic upper gastrointestinal endoscopy were randomized into 2 groups. While the patients in the first group did not receive sedation during upper gastrointestinal endoscopy, the patients in the second group were sedated with intravenous midazolam at the dose of 5 mg for those under 65 years or 2.5 mg for those...

Autores: Garlet,Q.I.; Pires,L.C.; Silva,D.T.; Spall,S.; Gressler,L.T.; Bürger,M.E.; Baldisserotto,B.; Heinzmann,B.M.
(+)-Dehydrofukinone (DHF) is a major component of the essential oil of Nectandra grandiflora (Lauraceae), and exerts a depressant effect on the central nervous system of fish. However, the neuronal mechanism underlying DHF action remains unknown. This study aimed to investigate the action of DHF on GABAA receptors using a silver catfish (Rhamdia quelen) model. Additionally, we investigated the effect of DHF exposure on stress-induced cortisol modulation. Chemical identification was performed using gas chromatography-mass spectrometry and purity was evaluated using gas chromatography with a flame ionization detector. To an aquarium, we applied between 2.5 and 50 mg/L DHF diluted in ethanol, in combination with 42.7 mg/L diazepam. DHF within the range of...

Autores: Silva,L.L.; Garlet,Q.I.; Benovit,S.C.; Dolci,G.; Mallmann,C.A.; Bürger,M.E.; Baldisserotto,B.; Longhi,S.J.; Heinzmann,B.M.
This study evaluated the sedative and anesthetic effects of the essential oils (EO) of Hyptis mutabilis (Rich.) Briq. and their isolated components on silver catfish (Rhamdia quelen). Quantitative chemical differences between the EOs obtained from leaves and inflorescences were verified, and a new chemotype rich in globulol was described. Although there were no significant differences in the time of induction for sedation and anesthesia between the EOs, only the leaf EO at 344 mg/L anesthetized all fish without side effects. Fractionation of the leaf EO was carried out by column chromatography. The isolated compounds [(+)-1-terpinen-4-ol and (-)-globulol] showed different activity from that detected for the leaf EO in proportional concentrations and...

Provedor de dados: 65
Autores: Zeppenfeld,Carla Cristina; Brasil,Marisa Teresinha de Bastos; Cavalcante,Gisela; Silva,Lenise Vargas Flôres da; Mourão,Rosa Helena; Cunha,Mauro Alves da; Baldisserotto,Bernardo.
ABSTRACT: Anesthetics are effective to reduce or minimize stress in handling operations related to fish cultures. Aiming to avoid residual effects of synthetic drugs, several natural agents, such as essential oils (EOs), have been tested. The aim of this study was to determine the optimal concentration of the EO of Ocimum micranthum for induction of anesthesia in juveniles of silver catfish (Rhamdia quelen) and grass carp (Ctenopharyngodon idella). Results demonstrated that the most suitable concentration to sedate silver catfish and carp is 25μL/L, while to anesthetize 200μL/L is more suitable for silver catfish and 100μL/L for grass carp, because these concentrations induce deep anesthesia in less than three min and recovery in less than five min....
