BRIEF RESUME OF THE INTENDED WORK:
6.1. NEED OF STUDY:
Liver disease is considered as the major problem worldwide, as liver has supreme
importance due to its functional involvement in metabolism, detoxification of xenobiotics, drugs, chronic alcoholism, in the alteration of homeostatis1.
Liver plays a important role in detoxification and excretion of many endogenous
and exogenous compounds. Any impairment in the functions of liver may lead to many
implications on health. Management of liver disease is still a challenge to the modern
scientific community2.
Liver injury is caused due to infections, certain drugs, environmental and social factors such as alcoholism3 resulting in severe pathological conditions such as hepatitis,
liver cirrhosis, hepatosis4. Conventional or synthetic drugs used in the treatment of liver
diseases are often inadequate and can have serious adverse effects. As a result, there is a
worldwide trend to go back to traditional medicinal plants. Many natural products of
herbal origin are in use for the treatment of liver ailments5.
There are number of polyherbal formulations which have been widely marketed,
claiming to be highly effective in the treatment of above mentioned organ disorder.
Many polyherbal formulations are widely used but most of them are not scientifically
validated yet.
COMPOSITION OF LIVOPICK:
Each capsule contains processed extracts of:
Latin Name
Quantity
Rheum emodi
50mg
Picrorhiza kurroa

The above medicinal plants possess antioxidants, hepatoprotective, antidiabetic,
antihistaminic, antibacterial properties. Rheum emodi7, 8- anthelmentic, hepatoprotective, laxative. Picrorrhiza kurroa9, 10-antipyretic, hepatoprotective, cathartic, tonic, laxative, anti-allergic, anti-anaphylactic, anti-epileptic, anti-paralytic, anthelmentic, appetizer, anti-ulcer. Plumbago zeylanica10- anti diabetic, antioxidants, hepatoprotective activity, anticancer, antifungal activity. Phyllanthus niruri11, 12- dysentery, influenza, vaginitis, tumours, diabetes, diuretics, jaundice, kidney stones and hepatoprotective. Andrographis paniculata20, 21- hepatoprotective and hepatostimulative agent. Eclipta alba13, 20-inflammation, anthelmentic, digestive, anti-hepatotoxic. Boerhavia diffusa13, 20asthma, dyspepsia, tumours, abdominal pain, diuretic and liver disorders. Tinospora
cordifolia14,15-hepatoprotective,
immunomodulatory
activity.
Triphala16-anti-
inflammatory, anticancer, hepatoprotective, anti oxidant property.
LIVOPICK is the polyherbal formulation contains the extract of the above medicinal
plant. Individually all the above is proved to be hepatoprotective but no scientific report
is available for its combined hepatoprotective effect. Hence the present study is aimed
to investigate the hepatoprotective activity of the Polyherbal formulation “LIVOPICK”.
6.2. REVIEW OF LITERATURE:
Liver diseases have become one of the major causes of morbidity and mortality in
man and animals in the world. Liver is an important target of the toxicity of drugs, xenobiotics, and oxidative stress. The major causes for the liver disorders are excessive
alcohol consumption, viral influenced liver diseases, drug induced, environmental toxins like lead, phosphorus, petrochemicals, etc17. The major liver disorders are hepatitis,
fatty liver, liver cirrhosis, and genetic diseases.
The mechanism behind the Carbon tetrachloride toxicity is in the liver. CCl4 is metabolized to the highly reactive trichloromethyl radical. The free radical generated
would lead to auto-oxidation of the fatty acids present in the cytoplasmic membrane
phospholipids and causes functional and morphological changes in the cell
4
membrane22. In acetaminophen toxicity, nitric oxide (NO) scavenges superoxide to produce peroxynitrite, which then causes protein nitration and tissue injury18. In thioacetamide induced hepatotoxicity is mediated by oxidative stress caused by the action of
cytokines through lipid peroxidation23.
Livopick is a polyherbal formulation, developed by Wilson Drugs and Pharmaceutical
Pvt. Ltd. India and is intended to use in jaundice, infective hepatitis, cirrhosis and also
loss of appetite, indigestion, habitual alcoholism.
 Rheum emodi belongs to the family Polygonaceae. The most important constituents of the Rheum emodi are anthraquinone derivatives such as chrysophanol,
aloe-emodin, emodin, physcion, rhein and its glycosides. This reportedly to have
purgative, anthelmentic and hepatoprotective actions6 and its tuber as bitter tonic, laxative, appetite stimulant, diuretic, anti-bilious, and curative for sore eyes
and bruises. It has also been reported to have antifungal7 and hypoglycaemic
properties 8. Rheum emodi root is being commonly used in traditional medicine
as hepatoprotective .
 Picrorrhiza kurroa belongs to the family Scrophulariacea contains picrorrhizin,
kutkin, picroside, and apocynin. The plant is used for anti-pyretic, hepatoprotective9, cathartic, laxative, anti-allergic, anti-anaphylactic, anti-epileptic, antiparalytic, anthelmentic, apetizer, anti-ulcer, skin diseases, antidote for dog bite
and as a anti-histaminic activity.
 Plumbago zeylanica belongs to the family Plumbagenaceae. It is having anti diabetic, antioxidants, hepatoprotective activity10 , anticancer, antifungal activity.
 Phyllanthus niruri 12 belongs to family Euphorbiaceae. It has been claimed to be
an excellent remedy for jaundice and infective hepatitis. The whole plant is used
as remedies for many conditions such as dysentery, influenza, vaginitis, tumours, diabetes, diuretics, jaundice, and kidney stones. The plant is also useful
for treating hepatotoxicity, hepatitis B, hyperglycaemia and viral and bacterial
diseases 11.
 Andrographis paniculata20 (Kalmegh) belongs to the family Acanthaceae. It is
used extensively in the Indian traditional system of medicine as a hepatoprotective and hepatostimulative agent12. The aqueous extract of the
5
leaves of this plant has traditionally been used for treatment of various liver disorders and jaundice.
 Eclipta alba13 belongs to the family Astragenaceae contains wedelolactone, thiophene, furanocoumarins, demethylwedelolactone, ecalbutin, echinocystic acid,
flavones: luteoline, oleanic acid and ursolic acid. The plant used for antiinflammation, anthelmentic, digestive, anti-hepatotoxic20.
 Boerhavia diffusa
13
belongs to the family Nyctagenaceae contains sitosterol,
tetracosanoic, arachidic acid, hentriacontane, ecdysone and triacontanol. The
plant is used for blood impurities, asthma, dyspepsia, tumours, abdominal pain,
diuretic and liver disorder.
 Tinospora cordifolia belongs to the family Menispermaceae. It has been reported
that the extract of this is has free radical scavenging and antioxidant properties14.
It is also reported to have hepatoprotective, immunomodulatory activity15.
 Triphala16,
19
is the most commonly used in the Indian Ayurvedic formulation
comprising the equal parts of Terminalia chebula(Combretaceae) Extract, Terminalia bellerica (Combretaceae) Extract, Emblica Officinalis (Euphorbiaceae)
Extract. It possess antiinflamatory, hepatoprotective, anti oxidant property.

RATS25,26,29:
PROCEDURE:
Carbon tetrachloride (CCl4) induced liver injury. The animals will be divided into 5
groups consisting of six animals. The animals will be then subjected to either one of the
following treatments for 9 days. The CCl4 will be administered after dilution with liquid
paraffin the ratio of 1:1. Food will be withdrawn 12 hrs before CCl4 administration to
enhance liver damage in animals of groups 2, 3, 4 and 5. The animals will be sacrificed
24 hrs after the administration of CCl4. Blood samples will be collected by retro-orbital
puncture method and serum is used for assay of marker enzymes.
The liver will be isolated and washed with normal saline, dried using filtered paper and
weighed immediately. The liver will be then subjected to histopathological examination.
