Garlic
can play 'a major role' in combating TB: Study
ALIGARH,
Dec 27:
Researchers at the Jawaharlal Nehru Medical
College of Aligarh Muslim University have claimed
that garlic can play "a major role" in
combating tuberculosis, especially the drug
resistant version of the disease.
"Garlic acts
as an effective herbal therapeutic. It is a
strong anti-oxidant and anti-inflammatory agent
having beneficial effects on the immune
system," said Najmul Islam, the head of a
research project on garlic.
Islam said allicin
from garlic is a valuable natural anti-oxidant
that helps combat tuberculous. "It serves as
a safe and economical alternative to
antibiotics."
The findings of
the researchers have been published in the latest
issue of the prestigious scientific journal of
the Federation of European Biochemical Societies
(FEBS).
In the past few
years, researchers of J N Medical College,
Holland's University of Utzech and South Korea's
Chungnam National University have been
independently conducting a study on immune
responses in human tuberculosis, a major health
hazard across the world today.
It was only in the
late 20th century that western scientists
accepted the benefits of garlic in controlling
blood pressure in the human body.
However, the
research in India, Holland and South Korea has
for the first time scientifically established
garlic's curative role in preventing TB and
treating the disease.
The promise held
by the "new garlic technology" has
excited western scientists to the extent that
they have been quoted as saying that it "may
have an enormous impact upon health challenges
faced by the world today, including
antibiotic-resistant influenza epidemic,
biological threat, weight control, chronic
diseases and even have an impact on strategic
military men in the field".
Referring to the
findings, Bill Sardi, president of knowledge of
health Incorporated in the US, said "this
achievement is long awaited and may rival the
discoveries made by Pasteur and Flemming".
Sardi, addressing
an international conference in New Jercy
recently, said "a fresh clove of garlic
macerated in a hand press will yield about 5250
micogrammes of allicin.
"But allicin
is a transient molecule that cannot be released
in garlic powder, only from fresh crushed cloves.
Two components of garlic must mix together when
garlic powder enters the stomach. An enzyme
called allinase must mix with alliin in order to
form allicin. But stomach acid quickly destroys
allinase and little or no allicin is
produced."
Islam, who has
been flooded with offers for collaborative work
in recent weeks, told PTI a very significant
aspect of the findings is that garlic capsules,
which till now were being widely promoted by drug
manufacturers, are not really effective for the
simple reason that digestive acids and enzymes in
the stomach prevent the formation of allicin.
In sharp contrast,
if a clove of garlic is simply chewed and kept
under the tongue for a couple of minutes, the
anti- oxidant role of allicin starts manifesting
itself within minutes, he said.
Islam said the
significance of this natural oxidant is that it
does not require any sophisticated storage and
delivery systems. Thus, the possibility of losing
its potency in any storage conditions and time in
comparison to known medicines for TB is nearly
nil. It is easily available globally and has
extremely low cost and is thus within reach of
all persons in developing countries.
Apart from Islam,
the study was conducted by Nazrul Hasan and
Nabiha Yusuf (University of Birmingham in the US)
and Zahra Tousse (Case Western Reserve University
at Cleveland in the US). (PTI)
Falling
research standards worry policy makers
NEW
DELHI, Dec 27: Indian science tasted both
successes and setbacks in 2006 which saw the
country join the select group of nations in
pursuing the unique fusion energy project while
concerns on falling standards of research worried
policymakers.
Scientists
suffered the biggest setback this year when the
launch of the heaviest communications satellite
failed as the Geosynchronous Satellite Launch
Vehicle (GSLV) veered off course and exploded in
July.
However,
undeterred by the loss, leading space scientists
backed the idea of undertaking a manned space
mission by 2014.
India, along with
six other partners - the European Union (EU),
Russia, China, Japan, South Korea and the US,
signed a formal agreement to build an
experimental nuclear fusion reactor that aims to
produce energy from nuclear reactions like those
that fuel the Sun.
The International
Thermonuclear Experimental Reactor (ITER) to be
built in Cadarache, in southern France, over a
decade starting 2007, if successful, could
provide energy that is clean and almost
limitless.
The ambitious
Indo-US civil nuclear deal also saw atomic
scientists come out of their highly secretive
world and get involved in the decision making
process.
The advocacy by
the scientific leaders made India's position in
negotiations stronger than before in putting
forth its views and reservations on the ongoing
process of reaching full cooperation on civil
nuclear issues with the US.
Top scientists
like former Atomic Energy Commission chairmen P K
Iyengar and Homi Sethna, with memories of their
experience with Tarapur project for which the US
cut off fuel supplies after the reactor was
built, intervened to see that deal does not
compromise the country's strategic programme.
The heavy
rainfall, experienced in Mumbai last year,
repeated this year in some parts of the country
inundating Bangalore, parts of Bihar and even
desert areas of Rajasthan.
Indian
meteorologists, in a study, claimed that global
warming was boosting the power and number of
storms and other extreme weather events across
the world. They also warned of increasing risk
from heavier rains during the season in parts of
Central India.
Prime Minister
Manmohan Singh expressed concern over the falling
standards of scientific and technological
research, and said the Government was evolving a
strategy to rejuvenate science.
It included not
only making a career in science an attractive
proposition but also simplifying the visa regime
and employment regulations in universities and
Government institutions to encourage a
"reverse brain drain."
The year began
with ISRO announcing that it had developed has
successfully carried out tests on the
indigenously designed and developed Supersonic
Combustion Ramjet (Scramjet), a precursor to
air-breathing rockets that would make space
launches cheaper.
It said that
through a series of ground tests, a stable
supersonic combustion had been demonstrated for
nearly seven seconds with an inlet Mach number of
six. (ie six times the speed of sound).
An aircraft having
scramjet engines could dramatically reduce the
travel time and put any place on earth within a
90-minute flight. At least 11 countries have
active scramjet programmes in place.
The year also saw
senior nuclear scientists, used to working in
their secretive worlds, come out in the open with
legitimate concerns on the Indo-US civil nuclear
deal and were involved by Prime Minister Singh in
the decision making process at various stages of
the crucial pact.
The year also saw
the Ministry of Earth Sciences carved out of the
Ministry of Science and Technology. The new
ministry comprises the Department of Ocean
Development and the Indian Meteorological
Department, which also includes the Seismological
Institute and the corresponding components like
Earthquake Risk Evaluation Centre and Programme
Personnel from the Department of Science and
Technology. Both the ministries are headed by
Union Minister Kapil Sibal.
The S&T
ministry released the first database of digitized
inventories on bio-resources containing
information onplant resources, animal resources,
microbial resources and marine resources in the
form of nine compact discs (CDs).
Called 'Jeeva
Sampada,' the inventory of India's vast
bio-resource provides data on 39,000 species
offers images, distribution maps and an
interactive data retrieval system.
It offers
information in 10 modules on taxonomy
distribution, uses, chemical composition,
economic potential and other literature on 2,700
medicinal and economically important plants,
9,000 species of animals, 17,000 microbes and
7,000 marine organisms.
A web-based portal
called the Indian Bioresource Information
Network, which seeks to network the otherwise
independent databases and information on the
country's biodiversity as one window system for
the benefit of research scientists, bio-resource
managers, policy makers, entrepreneurs and the
common man was also launched.
India ranks 14th
in the world in number of research papers
published in peer review journals every year.
Senior officials
said India's scientific competitiveness, as
measured by the number of publications in
research journals listed by the Science Citation
Index, was not proportional to its inherent
strength in science.
The ministry has
sought Rs 1.25 lakh crore allocation in the 11th
Plan to fund among others a series of
interventions that could improve India's global
Science Citation Index ranking from 14th to
seventh.
Among the measures
planed to attract talented school students to
careers in science include guaranteed funding
from the age of 17 through 32 so they can pursue
their education and early careers in research.
The ministry also
plans to organise scientific summer camps
attended by Nobel laureates and famous Indian
scientists for the top one per cent of students
passing out of schools.
With India hosting
the Commonwealth Games in 2010, efforts are on to
provide venue specific weather forecasts, real
time display of current weather observations and
five day predictions for each venue including on
rain, clouds, temperature, wind and visibility.
The system would
require deployment of a dense networks of
Automatic Weather Systems, Doppler Radars, wind
profilers and use of high-end computing systems.
Two years after
the Indian Ocean tsunami killed an estimated
300,000 people, progress has been made on setting
up basic early warning systems in the region.
An interim tsunami
warning system, comprising seismometers,
high-tech buoys, and communication systems, is
already in place and had generated alerts when
earthquakes shook the Indonesia-Andaman and
Nicobar islands region.
The year also saw
the ministry unveiling a slew of technology
intiatives to help a range of activities -- from
digital eyes to monitor illegal constructions in
the capital to digitisation of crime records.
India also signed
agreements for strentgthening cooperation in
scientific research with many countries including
China, Norway, Japan, the United States and the
ASEAN.
The thrust was to
develop the market in the India-China-ASEAN
region that is home to one half of the world
population.
The year was
marked with at least two key discoveries -- a new
species of bird and a rare medicinal plant --
both in the northeastern state of Arunachal
Pradesh.
The rare species,
found by an astronomer and an avid bird watcher
Ramana Athreya, has been named Bugun Liocichla -
only 14 of these birds are known to exist.
Begonia
Tessaricarpa, a rare medicinal plant, believed to
be extinct, was rediscovered after 115 years by
Kumar Ambrish and M Amadudin, scientists of the
Botanical Survey India (BSI) in Arunachal
Pradesh. (PTI)
