ABSTRACT
@#Necrotising pneumonia or lung gangrene is a challenging problem and it is diagnosed more often today, especially in tertiary hospitals. It is always a challenge to treat these patients as they are usually immunocompromised and are often ill when the diagnosis is made. We report three immunocompromised patients with necrotising pneumonia who were treated surgically. We share the outcomes of these patients and discuss the management of necrotising pneumonia in the immunocompromised.
ABSTRACT
Cellulose is a linear homopolymer polysaccharide having water insoluble property. Various cellulose derivative prepared by etherification gains water solubility and shows thermoresponsive gelation. Thermoresponsive polymers are sensitive to thermal environment surrounding them and in response to it they show change in their property. Thermogelation behaviour of cellulose derivatives varies with degree and type of substitution. The main aim behind presenting this article is to summarize the thermosensitive property and application of various cellulose derivatives. This review stresses mainly on cellulose derivatives, methyl cellulose, hydroxypropyl methylcellulose and ethyl (hydroxyethyl) cellulose.
