Indian researchers develop bone substitutes from eggshells

Topic : Indian researchers develop bone substitutes from eggshells

Topic in Syllabus: Science & Technology

 

Context:

Indian researchers develop bone substitutes from eggshells

Indian researchers have developed a process by which bone implant materials can be synthesized from waste eggshells.

 

Significance:

This research will produce bone substitute materials such as ß-tricalcium phosphate (ß-TCP), a commonly used bone substitute material from natural sources, without the use of toxic chemicals, shared the institute in a release.

 

Key facts:

Eggshells are made of largely calcium containing minerals (95.1%) along with small amounts of proteins and water.

Sushruta Samhita, an ancient Sanskrit text on medicine and surgery, describes ‘Asthipoorana’ or bone grafting in which materials having calcium were combined with the latex of the banyan tree to form bone substitutes.

 

Sample Question:

The researchers at which IIT have developed bone substitutes from eggshells?

a. IIT Bombay

b. IIT Delhi

c. IIT Madras

d. IIT Hyderabad

 

Answer: d

The researchers at IIT Hyderabad and BR Ambedkar National Institute of Technology (NIT) of Jalandhar have developed a process by which bone implant materials can be synthesized from waste egg shells. They seek to produce bone substitute materials such as – Tri-Calcium phosphate (TCP) without the use of toxic chemicals. The natural source of choice of the IIT-Hyderabad researchers is egg shells. Eggshells are made up largely of calcium (95.1%) along with small amounts of proteins and water. In modern medicine, damaged and missing bones are replaced with bone from either patient or donor, or by using artificial materials containing calcium, such as Plaster of Paris, and phosphate compounds like hydroxyapatite and calcium phosphate. TCP is a commonly-used bone substitute material from natural sources.
