The effects of the KA on the sleep time were observed using a hypnosis test, and the tail-withdrawal latency was analyzed using the tail-withdrawal test. In the hypnosis test, KA (2.5, 5 or 10 ng; icy administered) treatment had no distinctive effects on the sleep time of mice treated with emulsified inhalation anesthetics. In the tail-withdrawal test, KA (0.2, 0.4 or 0.8 ng; it administered) treatment significantly and dose-dependently decreased the tail-withdrawal

latency of mice treated with emulsified anesthetics. These results suggested that KA receptors may modulate the analgesic but not hypnotic effects induced by emulsified en flurane, isoflurane or sevoflurane.”
“Lesch-Nyhan disease (LND), a genetic disorder associated with motor and psychiatric disturbance and self-injurious behaviour (SIB) is Caused by a complete deficiency of hypoxanthine-guanine Staurosporine phosphoribosyltransferase

(HPRT). The connection between enzyme deficiency and neurological involvement is still unclear. Evidence exists for a role of basal ganglia dysfunction with decreased dopamine and excess serotonin SBE-β-CD striatal content. In this Study, we investigate the role of serotonin receptor 2C (HTR2C) in the brains of HPRT gene knock-out mice, a model of LND. HTR2C expression is analyzed by real-time polymerase chain reaction (PCR) using SYBR-green detection methods. The percentage of edited HTR2C mRNA was determined by direct sequencing of amplification products of the region containing the editing sites. We found a 55% increase in the expression of HTR2C gene but no significant difference in mRNA editing levels between knock-out and control mice. The above alteration found in HPRT-deficient mice is similar to

those found in other animal models used to Study aggressive and self injurious behaviour. (C) 2009 Elsevier Ltd. All rights reserved.”
“Premature luteal demise or luteal insufficiency is not well characterised find more as a cause of pregnancy loss in domestic species, including horses. In this report, a mare inseminated with cooled-transported semen at our facility returned for a routine pregnancy diagnosis at 15 days post ovulation. Ultrasonography per rectum revealed endometrial oedema and the absence of visual indication of a corpus luteum on either ovary. Nonetheless, an embryonic vesicle small for the gestational age was identified. Daily oral altrenogest treatment was implemented immediately. Serum progesterone concentration was 0.67 ng/ml, which is below the threshold considered adequate for pregnancy maintenance in the mare. Examinations were repeated at 17, 25, 30, 39, 49, 72 and 120 days post ovulation. At 25 days post ovulation the embryonic vesicle presented normal development for the gestational age. In addition, sequential blood samples were collected to measure progesterone, equine 432 chorionic gonadotrophin and oestrone sulphate concentrations.
