BRIEF RESUME OF THE INTENDED WORK :
6.1 NEED FOR THE STUDY:
According to the findings of the National Vital Statistics Report (2008) and the
Morbidity and Mortality Weekly Report (2007) of the Centers for Disease Control
and Prevention (CDC), cardiovascular diseases including myocardial infarction (MI)
and the resultant complication in cardiac function represent the leading cause of
morbidity and mortality in developed countries1,2. Moreover, with advanced life style
in developing countries, such as India, particularly in metropolitan cities, MI is
making increasingly important contribution to mortality statistics of such countries3.
Although clinical care is improved, public awareness is raised and health innovations
are widely used, myocardial infarction remains the leading cause of death worldwide4.
It is the acute condition of myocardial necrosis that occurs as a result of imbalance
between coronary blood supply and myocardial demand. Experimental and clinical
studies have shown that there is increased generation of reactive oxygen species such
as superoxide anion (.O-2) and hydroxyl radicals (.OH-) in heart failure, which are
involved in the formation of lipid peroxides, damage of cell membrane, and
destruction of antioxidative defense system 5,6.
Cell injury occurring after ischemia-reperfusion (I/R) in the heart is attributed to
necrosis caused by calcium overload, acidosis, and oxidative stress. After I/R,
myocardial cell die by necrosis and/or apoptosis. Free radicals and antioxidants play
an important role in cellular damage that can cause atherosclerosis and myocardial
infarction. Both neutrophils and free radicals, such as superoxide anions, hydroxyl
radicals and hydrogen peroxide, can cause oxidative damage to cell lipids, proteins,
and nucleic acids. A consensus still exists that reactive oxygen species play an
important role in the pathogenesis of cardiac reperfusion injury.7
Because of high incidence of morbidity, various drugs and regimes have been
advocated for the control of CVS diseases. Many new drugs have been introduced
which may demonstrate better efficacy but possess side effects.8 Recently attention
has been focused towards herbal and mineral preparations which are traditionally used
as potential therapeutic agents in the prevention and management of cardiovascular
diseases such as Terminalia arjuna (arjun), Trigonella foenum-graecum (fenugreek),
Curcuma longa (turmeric), Garcinia indica (kokum) and Vitis vinifera (grapes).9
CRITERIA FOR SELECTION OF THE PLANT:
Roots of Pseudarthria viscida was proved for its anti diabetic, antioxidant, antidiarrhoeal activity and neuroprotective activity. Pseudarthria viscida consists of
phytochemical constituents like alkaloids, glycosides, flavonoids, tannins, phenolic
compounds and saponins. Alkaloids, glycosides, saponins and flavonoids were
reported to show cardioprotective activity.10Also in Ayurveda Pseudarthria viscida
was found in many formulations used for cardio protective action.11In present study,
cardioprotective effect of Pseudarthria viscida will be assessed by using different
experimental models in animals.

7.2.3ANIMALS
Wistar rats (150-200 g)of either sex will be procured from Indian Institute of
Sciences. They will be maintained under standard conditions (temperature 22 ± 2oC,
relative humidity 50±5% and 12 h light/dark cycle).The animals will be housed in
sanitized polypropylene cages containing sterile paddy husk as bedding. They will
have free access to standard pellet diet and water ad libitum. The Institutional Animal
Ethics Committee approved the experimental protocol. All the animals received
human care according to the criteria outlined in the “Guide for the Care and Use of
Laboratory Animals” prepared by the “National Academy of Sciences” and published
by the “National Institute of Health”. All the procedures will be performed in
accordance with Institutional Animal ethics committee constituted as per the direction
of the committee for the purpose of control and supervision of experiments on
animals (CPCSEA), under ministry of animal welfare division, Government of India,
New Delhi, India.
7.3 EXPERIMENTAL METHODS :
7.3.1.ISOPROTERENOL (ISO) INDUCED MYOCARDIAL NECROSIS IN
RATS12.
The albino rats (150-200 g) of either sex will be randomly divided into 5 groups of 6
each and assigned as below:
o Group-I- normal control (Normal saline)
o Group-II - toxic control (Isoproterenol: 150mg/Kg)
o Group-III–Reference standard (Propranolol: 10mg/Kg)
o Group-IV- Pseudarthria viscida roots extract (low dose: 200 mg/Kg)
o Group-V- Pseudarthria viscida roots extract(high dose: 400 mg/Kg)
Propranolol will be administered to group III animals one week before administration
of Isoproterenol. All the animals in group IV & V will be treated once daily post
orally for 4 weeks. On 29th and 30th day after the treatment, myocardial infarction will
be induced in group II – group V animals by sub cutaneous injection of Isoproterenol.
EVALUATION:
Symptoms and mortality in each group will be recorded and compared with animals
given with Isoproterenol alone. Forty-eight hours after the first Isoproterenol
administration, the rats will be sacrificed and autopsied. The hearts will be removed
and weighed and the frontal sections will be embedded for histopathological
examination.
BIOCHEMICAL ESTIMATION:
The collected blood as well as heart homogenate will be analyzed for endogenous
biological markers such as Lactate dehydrogenase (LDH), Creatine phosphokinaseMB (CK-MB) and antioxidant enzymes like Superoxide dismutase and Catalase.
7.3.2: ISCHEMIA-REPERFUSION INDUCED (IRI) MYOCARDIAL
DYSFUNCTION13
The albino rats (150-200 g) of either sex will be randomly divided into 5 groups of 3
each and assigned as below:
o Group-I-Normal control (saline)
o Group-II – Ischemia induced control
o Group-III – Ischemia induced + Reference standard (Propranolol: 10mg/Kg)
o Group-IV - Ischemia induced + Pseudarthria viscid roots extract (low dose:
200mg/Kg).
o Group-V- Ischemia induced + Pseudarthria viscid roots extract (high dose:
400 mg/Kg).
Propranolol will be administered to group III animals one week before producing
ischemia. All the animals in group IV & V will be treated once daily post orally for 4
weeks. The heart will be excised from deeply anesthetized rats (35 mg/kg sodium
pentobarbitone, i.p) and perfused with Kreb-Henseleit solution gassed with carbogen
at 37o C and a constant flow rate of 5ml/min by one-way circulation using modified
Langendorff setup. Measurement of contractile force will be done with displacement
transducer and recorded on Student physiograph. After a short period of equilibrium
(15 minutes), records will be taken for a control period of 15 minutes, followed by 15
minutes ischemia and then a washout period with Kreb-Henseleit solution. Recovery
in terms of inotropic and chronotropic effect will be studied and the extent of
cardioprotection due to Pseudarthria viscida will be evaluated by measuring the
developed tension.
BIOCHEMICAL ESTIMATION:
The collected blood as well as heart homogenate will be analysed for endogenous
biological markers such as Lactate dehydrogenase (LDH), Creatine phosphokinase
(CK) and antioxidant enzymes like Superoxide dismutase and Catalase.
7.3.3 ECG STUDIES14.
The albino rats (150-200 g) of either sex will be randomly divided into 5 groups of 3
each and assigned as below:
o Group-I- normal control (saline)
o Group-II - toxic control (Isoproterenol: 150mg/Kg)
o Group-III – Reference standard ( Propranolol : 10mg/Kg)
o Group-IV – Pseudarthria viscida roots extract (low dose: 200 mg/Kg ).
o Group-V- Pseudarthria viscida roots extract ( high dose: 400 mg/Kg).
Propranolol will be administered to group III animals one week before administration
of Isoproterenol. All the animals in group IV & V will be treated once daily post
orally for 4 weeks. On 29th and 30th day after the treatment, myocardial infarction will
be induced in group II – group V animals by sub cutaneous injection of Isoproterenol.
After anesthetizing the rat with a combination of Ketamine hydrochloride (75mg/kg,
