Capsule

 

in biology:

  1. In animals and man, the membrane surrounding various organs and their parts (for example, the kidney, liver, or joint capsules) and also pathological formations (parasites that have implanted themselves in tissue, necrotic masses, foreign bodies). A capsule is composed primarily of fibrous connective tissue and sometimes of adipose cellular tissue.
  2. The gelatinous layer around a cell characteristic of the capsulated bacteria, formed from macromolecular substances produced by these microorganisms[11–1083^]

Capsule

 

(1) A dry dehiscent fruit with many seeds (sometimes with one seed), formed of two or several carpels. Capsules dehisce by means of a lid (plantain, henbane), tiny holes (poppy, bellflower), denticles on top of the capsule (primrose, pinks), or longitudinal splits (valves) along the septum (tobacco, hellebore) or along the valves (tulip, lily, hyacinth).

(2) The spore-bearing part of the sporangium of mosses. These capsules are either cylindrical or spherical.

The Bureau of Indian Standards ( BIS) has already come up with standards for vegetarian capsules. A BIS document claims that the cross- linking of gelatin and drug incompatibilities and the strict regulations regarding the use of animal derived gelatin requiring the absence of bovine spongiform encephalopathy ( BSE) ( commonly known as mad cow disease, a fatal neurodegenerative disease in cattle that causes a spongy degeneration of the brain and spinal cord) have encouraged the search for gelatin replacement.
