curare

(kyo͝orär`ē), any of a variety of substances originally used as arrow poisons by Native South Americans in hunting and in warfare. The main active substance of curare, tubocurarine, is an alkaloid extracted from Chondodendron tomentosum, Strychnos toxifera, and other plant species. The poison produces muscle paralysis by interfering with the transmission of nerve impulses at the receptor sites of all skeletal muscle. Muscles with many nerves, such as eye muscles, are affected first. In recent years curare has been put to medical use. When given in small quantities with general anesthesiaanesthesia
[Gr.,=insensibility], loss of sensation, especially that of pain, induced by drugs, especially as a means of facilitating safe surgical procedures. Early modern medical anesthesia dates to experiments with nitrous oxide (laughing gas) by Sir Humphry Davy of England

, especially in abdominal surgery, curare ensures the desired relaxation of muscle tissue with a minimal concentration of the anesthetic, lessening the possibilities of anesthesia-induced complications. Curare is also used to relieve spastic paralysis, to treat some mental disorders, and to induce muscle relaxation for the setting of fractures.

Curare

 

(from Carib kurari), a mixture of condensed extracts from plants of the genera Strychnos, Chondodendron, and other South American groups.

Upon entering the blood, curare blocks the transmission of neural impulses from the motor nerves to the skeletal musculature, causing muscular relaxation. Curare was used for centuries by natives of South America as an arrow poison. It contains a large number of alkaloids of the curarine group. Curariform agents are used for therapeutic purposes.

[kyü′rä·rē]
(organic chemistry)
Poisonous extract from the plant Strychnos toxifera containing a mixture of alkaloids that produce paralysis of the voluntary muscles by acting on synaptic junctions; used as an adjunct to anesthesia in surgery.

If one recalls that the subtitle to the first play is Alle radici di un sogno, and that, according to Curino, the roots of that dream begin with Sacerdoti and grow with Revel, it is possible to see how her muted enthusiasm stems from different origins than those critically condemned by others.
In her plays, Curino takes pains to distinguish between the industrial work culture at FIAT in Settimo Torinese and that of Olivetti in Ivrea.
Passione begins with Curino recounting the move with her seamstress mother from Torino to Settimo Torinese in FIAT housing during the 1960s.
In a reference to Pasolini's depiction of political corruption and urban ruin, Curino further stresses how industry conquered the natural world in her descriptions of Settimo Torinese, a land where not even fireflies roam since the fields where they once flocked no longer exist.
Almost ten years before Curino wrote Passione, she and her theater company, the Laboratorio Teatro Settimo, described the grotesque character of their city, which they likened to the peripheries of industrial metropolises that were also constructed for the sole purpose of corporate profit rather than public benefit.
Curino and her company here emphasize the ways in which capitalism triumphs over the needs of ordinary people.
The Olivetti that Curino celebrates is a company that managed to be profitable while providing a positive living experience for its workers, in sharp contrast with the companies that built the city that she calls home.
