Introduction
The Mood Elevator: Take Charge of Your Feelings, Become a
Better You. Human beings means we, all ride the mood elevator.
We want to get relief from huge work pressure or changing our
mood by using few mood elevators. We start our day in a great
place and high mood after a morning run and a good breakfast.
Betel quid (BQ) is one of the mood elevating food in the
world. An estimated 600 million people worldwide, 10% of the
world’s population, chew betel quid [1]. Betel quid chewing has
been common in South and Southeast Asia, Asia Pacific Region
for a long time [2]. Betel Quid (BQ) chewing, a habit practiced in
India and other Asian countries, has known to be associated with
cancer of the oral cavity. India has largest betel quid consuming
population in the world.The habit of chewing betel quid is due to
low cost, easily available and also as a mood elevator in the day
to day busy scheduled life.
There are several types of chewing habits in India featuring
use of betel quid (fresh betel leaf, fresh areca nut, slaked lime,
catechu and tobacco), pan masala (areca nut, slaked lime,
catechu, condiments and tobacco), mawa (areca nut, tobacco
and slaked lime). BQ products have been classified by the
International Agency for Research on Cancer (IARC) as group I
human carcinogens.
The major areca nut alkaloids are arecoline, arecaidine,
arecolidine, guvacoline and guacine [3]. Arecoline (1, 2, 4,
5,-tetrahydro-1-methylpyridinecarboxylic acid; molecular
weight 155.19) is the most abundant alkaloid of areca. These
alkaloids undergo nitrosation and give rise to N-nitrosamines
[4], which may produce a variety of Betel Quid-Specific
Nitrosoamines (BQSN). The BQSN interact with DNA, proteins
or other target forming adducts to exert its carcinogenic activity.
Slaked lime is also included in betel quid. It causes inflammation
in the submucosal area.
It was reported that the Ca(OH)2 of slaked lime in the
presence of the areca nut is responsible for the formation of
reactive oxygen species which cause oxidative damage in the
DNA of buccal mucosa cells those who chew the betel quid [5].
In addition to these ingredients of betel quid, tooth
attrition caused by the chewing action is also important for the
establishment and development of oral cancers.
Micronuclei (MN) have been proposed as good biomarker to
assess cytogenetic damage. MN formation has been observed in
cancer and pre-cancerous lesions of the oral cavity of betel quid
chewers. Statistically increased MN frequencies are observed
in the buccal cells of various stages of oral cancer cases either
may be in Pre Cancerous lesion or Pre cancerous condition. MN,
which acts as a cancer biomarker, highly increase than normal
in cancer cases and pre cancerous cases who had betel quid
chewing habit [6].
M. Sulkowska [7], observed that mitotic index count was
high in oral squamous cell carcinoma cases [7]. Mitotic Index
(MI) activity has proven to be an efficient prognostic indicator
of squamous cell carcinoma of various sites. Mitotic index are
higher in cancer and pre cancer (both betel quid and non betel
quid chewers) cases than normal. It was found that percentage
Abstract
Betel chewing is a popular habit in Asia. Oral squamous cell Carcinoma or Oral cancer is one of the most common malignancies in South
and South East Asian countries with betel quid chewing habit. Nitrosamines formed from alkaloids in betel nut during betel quid chewing may
be implicated in the etiology of oral cancer. Reactive Oxygen Species (ROS) are generated due to slaked lime which is also present in betel quid.
Mitotic activity has proven to be an efficient prognostic indicator of squamous cell carcinoma of various sites. Micronuclei (MN) have been
proposed as a good biomarker to assess cytogenetic damage. The present review focuses on the adverse effects of betel quid with different
abnormalities which acts as a mood elevator on Indian population.
