  • The nutritional significance of essential amino acids, as well as non-essential amino acids, is well documented in poultry production with regards to growth performance and protein accretion. However, the function of amino acids in the stress response is still unclear. L-Pipecolic acid, a L-lysine metabolite in the brain, induced a hypnotic and sedative effect acting via the ${\gamma}$- aminobutyric acid receptors. L-Arginine also induced a sedative effect via its metabolism to L-ornithine. In addition, three-carbon nonessential amino acids like L-alanine, L-serine and L-cysteine also induced sedative effects. These facts suggest that the requirement for amino acids in both essential and non-essential types may require reconsideration to add the concept of stress amelioration in the future.

  • Ponies were administered at the level of 0.1mg per kg of body weight of acetylpromazine malate through the jugular vein. Sedative effect, clinical signs such as body temperature, and changes of red blood cell counts and serum glucose concentration were investigated. Sedation was induced 5 to 6 minutes after injection of acepromazine and sedative effect was lasted for 30 to 40 minutes. Responsive reactions, however, to external stimuli were remained. Change of body temperature was not observed and heart beat was increased at the stage of induction and respiratory rate was decreased during the sedative period. Red blood cell count was considerably decreased during sedation, and concentration of serum glucose showed a tendency to increase gradually from the induction.

  • This study was performed to assess clinical signs, sedative effect and clinicschemical profile of a mixture of fentanyl-azapemne-xylazine(Fentazine$^{(R)}$) in formed elk Twelve male elk(Cervus canadensis) were immobilized with Fentazine, and blood samples were taken of femoral venous blood. Samples were analyzed in the conditions of 10- and 30-minute after administration of the drug. Heart rates, respiratory rates, and body temperatures were in normal ranges during Fentazine anesthesia. After iqiection of Fentazine, most of elk were recumbency and did not respond to needle prick In young adult(3.5.4.5 years old) elk a high dose(>3.0 ml/head) of Fentazine does not result in more sedation, but it does prolong the duration of sedative effect. Fentazine induced sufficient analgesia far velvet antler removal and hoof trimming in elk Salivation, urination, intermittent apnea and mild bloat were observed in elk Globulin, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, calcium, magnesium and phosphorus values were in normal ranges for at least 30 minutes after Fentazine administration. Total protein, albumins cortisol and prothrombin values were slightly increased during sedation(p<0.05). It was concluded that Fentazine is effective analgesic drug being useful for velvet antler removal and hoof trimming.

  • The purpose of this study was to assess the sedative effect of intranasal spray with midazolam for management of the uncooperative 20 children aged from 24 months to 92 months who required extensive treatment. The patients were given randomly a dose of 0.2mg/kg of intranasal placebo, intranasal spray with midazolam, and intranasal drop with midazolam. All the children were restrained in a pediwrap and were monitored with pulse oximeter for assessing the pulse rate and peripheral oxygen saturation. According to Fukuta's behavior rating scale, behavior was checked for evaluation of the clinical sedative effect. The obtained results were as follows: 1. Behavior score of intranasal spray with midazolam was lower than intranasal drop with midazolam(P<0.01). 2. Pulse rate was a significant change as a function of dental procedure(P<0.001), however the peripheral oxygen saturation was not influenced significantly by either adiministration route of drug or dental procedure. Clinically, intranasal spray with midazolam were safe and effective sedation in young children undergoing pediatric dental procedures.

  • The present study investigated the sedative effects of Sophora flavescens (SF) and its bioactive compound, matrine through performing locomotor activity test and the electroencephalography (EEG) analysis in the rat. The underlying neural mechanism of their beneficial effects was determined by assessing c-Fos immunoreactivity and serotonin (5-HT) in the brain utilizing immunohistochemical method and enzyme-linked immunosorbent assay. The results showed that SF and matrine administration had an effect on normalization of caffeine-induced hyperactivity and promoting a shift toward non-rapid eye movement (NREM) sleep. c-Fos-immunoreactivity and 5-HT level in the ventrolateral preoptic nucleus (VLPO), a sleep promoting region, were increased in the both SF and matrine-injected groups. In conclusion, SF and its bioactive compound, matrine alleviated caffeine-induced hyperactivity and promoted NREM sleep by activating VLPO neurons and modulating serotonergic transmission. It is suggested that SF might be a useful natural alternatives for hypnotic medicine.

  • This study was performed to determine the composition of phenolic substances contained in the leaves of Cirsium setidens (Compositae), validate the high-performance liquid chromatography (HPLC) method, and determine the in vivo sedative effect of the main component pectolinarin. Six phenolic compounds isolated from C. setidens were spectroscopically identified as chlorogenic acid (1), hyperoside (2), 3,4-di-O-caffeoylquinic acid (3), caffeic acid methyl ester (4), linarin (5), and pectolinarin (6) and then used as standard compounds for HPLC analysis. HPLC proved to be precise, accurate, and sensitive for the simultaneous analysis of the phenolic substances. In particular, six compounds showed good regression ($R^2$ > 0.999) within test ranges and recovery was in the range of 95.4 - 104.8%. The content of pectolinarin was considerably higher (156.48 mg/g) than those of other phenolic substances including the other flavone glycoside, linarin (18.99 mg/g). The contents of other phenolic substances, in order, were chlorogenic acid (8.41 mg/g), 3,4-di-O-caffeoylquinic acid (5.74 mg/g), hyperoside (4.33 mg/g), and caffeic acid methyl ester (0.51 mg/g). Oral administration with compound 6 (10 and 20 mg/kg) enhanced the sleeping time induced by pentobarbital in mice, indicating that it has a sedative effect.

  • The aim of this study is to evaluate the sedative effects of ethanol extract and the three major constituents of Cimicifugae Rhizoma. They decreased locomotor activity significantly, and enhanced sleeping duration induced by thiopental sodium. The ethanol extract of Cimicifugae rhizoma and 24-epi-7,8-didehydrocimigenol-3-xyloside (24-epi.) increased the $Cl^-$ influx into the intracellular area of SH-SY5Y neuroblastoma cells significantly. The present results demonstrate that the sedative effects of Cimicifugae rhizoma are mediated via the GABA-gated $Cl^-$ channel, partly by 24-epi.
