摘要:
The present invention provides for a curable polyurethane composition comprising a keto compound and a liquid mixture of an organic aliphatic polyfunctional polyisocyanate and a compound having active hydrogen, the keto compound having the general formula: ##EQU1## wherein R.sub.1 and R.sub.2 are each an alkyl group, an aromatic group, and a heterocyclic group, which may be the same or different, and R.sub.2 is a lower alkylene or alkenyl group having 1 to 2 carbon atoms. The curable polyurethane composition is characterized by exhibiting a long pot life due to the existence of the aforementioned keto compound therein.

A method for producing a non-human animal suffering from a spinal cord injury, which comprises interrupting an aorta at least at two sites, thereby forming an isolated segment of the aorta including branched parts of radicular arteries feeding the spinal cord between the sites of interruption, bringing the spinal cord to ischemia, and regionally administering glutamic acid or aspartic acid to the segment and a method for evaluating a medicament for treating a spinal cord injury due to glutamic acid or aspartic acid, which comprises interrupting an aorta of a non-human animal at least at two sites, thereby forming an isolated segment of the aorta including branched parts of redicular arteries feeding the spinal cord between the sites of interruption, bringing the spinal cord to ischemia, and regionally administering glutamic acid or aspartic acid together with a medicament for treating a spinal cord injury to the segment or a method for evaluating a medicament for treating a spinal cord injury due to glutamic acid or aspartic acid, which comprises administering a medicament for treating a spinal cord injury to a non-human animal produced according to the above method.
摘要:
Topical cooling of spinal cord, brain, esophagus, etc. can be selectively and continuously carried out under convenient control without causing any changes in internal pressure of spinal cord cavity, brain pressure, etc. by inserting a catheter, which has no hole connecting to the outside and in which a heat- cooling medium is circulated in its inner space to thereby cool a topical site; into the spinal cord, the epidural cavity, the subdural cavity or the subarachnoid cavity of the brain or the esophageal cavity and placing therein and then circulating the heat/cooling medium within the inner space of the catheter.

摘要:
A sand mold composition for the metal casting comprising a molding sand and pullulan as a binder therefor. As compared with prior art, the present composition has following advantages: in the molding step, no gas, dust, noise, or vibration is generated; in the pouring and sand stripping steps, neither noxious gas nor offensive odor is emitted; although the mold has a sufficiently high strength at room temperature for the convenient handling, it is readily broken down after the casting and so renders the knock-out and sand stripping very easy; and the recovered sand can be reused as such, practically without any after-treatment. The molding cycle is comparable to that of conventional oil sand or carbon dioxide-bonded mold.
