Fifty female patients who were selected to schedule for mammary gland tumor excision surgery, were divided into 2 groups(n=25 in each group): group A: received propofol's half-effective concentration at 3.0 μg/ml in Marsh model by TCI; group B: received propofol's half-effective concentration at 4.0 μg/ml in Marsh model by TCI. All patients were given remifentanil in Minto model by TCI after being given propofol which reached the balance between effect-site concentration and blood plasma concentration. The target concentration of remifentanil was determined by a modification of Dixon's up-and-down method. Laryngeal mask insertion was attempted after 10 mins, the insertion condition and success rate were observed, then the suitable target concentration of remifentanil(ECe50) were calculated.

The experts behind the discovery say elephants are capable of vocal imitation, joining a select group of animals that includes parrots, songbirds, dolphins, and humans.Zoologist Joyce Poole was the first to notice some rather unelephantine noises emanating from a group of semiwild, orphaned elephants in Tsavo National Park, Kenya. She managed to track the sounds to a female named Mlaika. But the ten-year-old's powers of mimicry were so developed that the task wasn't easy."I was sometimes unable to distinguish between the distant trucks and Mlaika's calling," said Poole, the scientific director of the Amboseli Elephant Research Project."This is what first made me wonder whether she could possibly be imitating the truck sounds."Poole said others in Mlaika's group have been heard to make a similar noise, which is quite different from any call previously recorded in elephants.
