Grave disease.(hyperthyroidisim)...c

In Graves ophthalmopathy the volume of the retro-orbital connective tissues and extra-ocular muscles is increased as a result of several causes

(1) marked infiltration of the retro-orbital space by mononuclear cells, predominantly T cells

(2) inflammatory edema and swelling of extra-ocular muscles;

(3) accumulation of extracellular matrix components, specifically hydrophilic glycosaminoglycans such as hyaluronic acid and chondroitin sulfate;

(4) increased numbers of adipocytes (fatty infiltration).

Grave disease.(hyperthyroidisim)...a


characterized by a triad of

Thyrotoxicosis, caused by a diffusely enlarged, hyperfunctional thyroid

Myxedema




apathy and mental sluggishness that may mimic depression

cold intolerant, and often obese.

Mucopolysaccharide-rich edema accumulates in skin and tissues, causing broadening and coarsening of facial features, enlargement of the tongue, and deepening of the voice.

may also result from inborn errors in metabolism (e.g., enzyme deficiencies)

What do you know about Bacteriophages?


nBacteriophages ( phages ) are obligate intracellular parasites that multiply inside bacteria by making use of some or all of the host biosynthetic machinery . They are viruses that infect bacteria.
Composition of Bacteriophage
nNucleic acid: either DNA or RNA but not both
nds DNA, ss RNA, ss DNA
nunusual or modified bases
nencode 3-5 gene products to over 100 gene products
nProtein: function in infection and protect the nucleic acid
