Video: Biotechnology in Medicine Video Lecture - NEET

hello friends this video on applications
of biotechnology part 6 is brought to
you by exam for your calm no more fear
from exam so with this we discussed
about biotechnology in agriculture now
let us look at the role of biotechnology
in the field of medicine so now we will
look at the application of biotechnology
in medicine now some of the few things
which have been developed or produced
with the help of biotechnology are
genetically engineered insulin now many
of you might know what does insulin it
is used for it is extremely useful thing
for diabetic patients so I will be
discussing about what is insulin why do
we use it and what is a genetically
engineered insulin so what are you in
this consider that it is a sort of
medicine for those who are suffering
from diabetes and we can as well
genetically engineer insulin gene
therapy gene therapy can again be useful
for a treatment of several diseases
biotechnology also turns out to be very
useful in the field of molecular
diagnosis that is an early detection of
several diseases now we will be talking
about all of these three different
applications of biotechnology one by one
question is is human insulin enough to
handle diabetics now what happens when a
diabetic patient is feeling really
uneasy because of because when the level
of glucose increases too much in the
blood there are many consequences of it
there are many things by through due to
which the patient might suffer for
example the heels do not wound fast
similarly and the wound do not heal fast
serval I need up he might have problems
of say heart or BP or any other disease
can attack that person quite easily he
gains a lot of weight so there are many
consequences when a person becomes
diabetic
now how to handle a baby
this happens due to the lack of insulin
so one simple way else to provide human
insulin from outside so if you are able
to provide human insulin from outside as
well as soon as insulin gets into the
body what will you do it will start
reducing the level of glucose in the
blood now the question is in a sense you
want to insert that insulin inside human
body you need human insulin and is human
now how do you create more and more
human insulin because we do not know
there might be several people who are
suffering from diabetes so we need a lot
of human insulin so how do we get that
human insulin so sometimes the stop of
human insulin is not enough so what is
there for replacement now I hear insulin
was extracted from pancreas of
slaughtered cattle and then that insulin
was inserted into the human body so
insulin was used from other animals when
human insulin was not available now you
can just understand that the body
structure of other animals and human
beings they are not exactly similar so
there might be several differences
between the human body and animal body
so when something from animals comes on
gendell inside the human body there are
chances that the body might not accept
it or there might be some adverse
reactions from the body so there were
certain disadvantages associated with
the usage of insulin from animals and
then inserting them into the human body
so some of the disadvantages where this
process was an expensive one now taking
out insulin from pancreas of slaughtered
cotton the process itself was quite
expensive it is a conflict process as
well because you actually need to check
the compatibility of that particular
insulin and the human being in inside
what it is going to be injected allergic
reactions can take place as a result of
different response of the human body due
to the entrance of that foreign insulin
so these are some of the disadvantages
which are associated with the use of
insulin obtained from other animals now
it was found later with the progress of
biotechnology and genetic engineering it
was found later that genetically also
insulin can be prepared so that genetic
engineering process can be used to
prepare insulin from bacteria so there
it is not that insulin which is present
inside the bacteria tis just that with
using bacteria human insulin can be
prepared so it is like human insulin is
getting prepared by making use of some
other organisms and bacteria they're
extremely easy to grow so now it is
under our control
the more insulin we want the more
bacteria we can grown and bacteria are
very easily available microorganisms
because they multiply very fast so you
can actually get a large number of
bacteria so this was extremely useful
and there started the story of
genetically engineered insulin from
bacteria so that is one very important
application of biotechnology in the
medical field sana thank you please
