The first thing to do is activate
EMS. Use cool or cold water to cool the burn for 10 minutes as soon as
possible. ( Do not use ice or frozen compress.) Early cooling will minimize the
depth of injury and decrease pain. Remove jewelry near the affected area. Cover
the injury with dry, clean pad loosely
to protect it. Do not give food or drink to injured person. Keep him comfortable
until EMS arrives and takes over.
A team of scientists is working to formulate a drug that can treat children who are diagnosed with gigantism. Gigantism is caused by the excess production of growth hormone by the pituitary gland present in the fore-brain. Growth hormone in turn signals the liver to produce a second harmone, Insulin-like Growth Factor-1 (IGF-1). The growth hormone and IGF-1 together tell the cells in the muscles, bones and skin to increase their number. Hence the possible effect of the administered drug will be to decreases the secretion of substances from the pituitary gland that cause growth.
