Abstract:
Phytophotodermatitis is a condition which is caused by contact with some plants containing furocoumarins. Furocoumarins in sap of fig tree are the main cause of its irritability when come in contact with the skin. The main symptoms are burning sensation and pain, itchy erythema, and edema, which usually begin 24 h after exposure. The leaf and root sap of the fig tree are the most potent parts causing irritant reaction. We report four children who were playing with fig tree leaves during a family picnic. They were referred to a burn center with second-degree burn in about 10% of total body surface area, due to phytophotodermatitis. Most people are not aware of the potential adverse effect of the plant. The improvement in general knowledge about the dangers of contacting fig tree leaves and sap and the benefits of suitable coverage at the time of harvesting or contacting fig tree may prevent such adverse effects.

Leaving Groups
In general, in a nucleophilic substitution reaction, a nucleophile displaces a functional group, called the leaving group, from the substrate to give a substituted product. A leaving group departs the substrate molecule through heterolytic cleavage, taking the pair of electrons with it to become a relatively stable weak base in the form of an anion or a neutral molecule.

Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
