Introduction
In the industrial world people are having some kind of problem
which may be largely man-made and iatrogenic in origin. Still, we ignore
and dismiss their growing incidence to factors which we assume are
not preventable. Alcohol abuse is one of the major problems in Indian
continent and is responsible for a signifcant percentage of hospital
admission. Ethanol molecule is small and soluble in both water and
lipids. It permeates all tissues of the body and afects most vital functions
of virtually all organs including brain, liver, kidney, heart and pancreas
[1]. Metabolism of alcohol leads to the generation of free radicals and
the chain reaction of lipid peroxidation that causes damage to the brain
and other vital organs. Terefore inhibition of free radical generation
is important in providing protection against hepatic damage. Toxicity
due to the alcohol consumption in the body leads to the changes in the
main organs, especially the brain. Te morbidity and mortality rate of
heavy alcohol drinkers have since been reported to have reached 6.1%
[2]. Alcoholic liver disease (ALD) is one of the most serious results of
chronic alcohol abuse in the world [3,4] have reported that the factors
that mediate the occurrence of ALD are acetaldehyde, oxidative stress,
hypoxia, immune response and membrane alterations. Antioxidants
play a signifcant role in protecting living organism from the toxic efect
of various chemicals by preventing free radical formation [5]. Now a
days, alcohol produces various dysfunctions in the human being. A
number of fsh has venomous sting, including the family Scorpaenidae.
Venomous species are only a few [6], as people consider it for edible.
Due to venom extracts storing have some technical difculties [7], the
source of marine organisms especially fsh, remain a largely unused
source of novel compounds. Te piscine venoms are efective on the
cardiovascular systems and mostly all the piscine venoms produce
profound cardiovascular changes. Generally, the piscine venom has
diferent components even though the similarities exist between
the responses to the venoms of all species of fsh. Numerous fsh
venom has been examined for activity in rats. Te oxidative stress is
involved in many diseases and reactive oxygen species can be useful
for immune system which might cure diseases. Terefore, these species
still represent sources of pharmacological compounds that may be
useful as research tools or lead compounds for drugs, and as such,
their pharmacological actions have been the focus of recent work [8,9].
Venom is delivered when the spine pierces the tissue of the victim, the
integumentary sheath enclosing the spine and venom is ruptured, and
the venom enters the wound [10,11]. Marine toxins represent a vast
source of novel pharmacological compounds that may prove useful
either as research tools or therapeutic agents [12]. Te venom of the
greater Weever fsh Trachinus draco contains high concentrations of
both histamine and catecholamine’s, and possesses cholinesterase
activity [13]. Te venom of the stingray Urobatix halleri contains
5-hydroxytryptamine (5-HT), 5-nucleotidase and phosphodiesterase
[14]. Te venom of all three species of stonefsh Synanceia trachynis, S.
horrida and S. verrucosa contain catecholamines [15], as well as a variety
of enzymatic activities [16]. In addition, the venoms of the stonefsh
S. trachynis, the lionfsh P. volitans and the freshwater stingray
Potamotrygon motoro are believed to contain either acetylcholine or a
cholinomimetic [9,17]. Hence, in the present study, attempts to evaluate
the toxicity of lionfsh P. volitans administered to rats and the incidence
of oxidative stress and neurotoxicity are made.
Materials and Methods
Specimens of P. volitans (Figure 1) were obtained from the local
aquarium, killed (by cooling), and the venomous spines were removed
and stored in 10% glycerol solution at -80°C. Te spines were thawed
and ground in a chilled mortar and pestle in 10% glycerol solution. Te
suspension was then centrifuged (7000 g, 10 mins) the supernatant
removed, the pellet resuspended again in approximately 1 ml of 10%
glycerol and recentrifuged. Te fnal supernatants were pooled, assayed
for protein concentration using a Bio-Rad Dc protein assay kit, and
adjusted to a concentration of 1mg/ml protein, before being aliquoted
and stored at -20°C until use and the venom was prepared as described
by [11]. Te protein was estimated by [18]. Te concentration was
adjusted to 1 mg/ml; aliquoted and stored at -20°C until use.
Abstract
The P. volitans generally is an edible fsh, it protein are considered to be a source of food for human and the venom
use for the development of new drugs. Pharmacological character of its venom were characterised during the study
period. The lionfsh venom shows the neuroprotective effcacy in alcohol intoxicated albino rat brain. These fndings are
further confrmed by histopathological observations. Therefore, the lionfsh venom could be used as a neuroprotective
agent.
