ENCLOSURE-I

06. Brief resume of Intended Work:

Need for the study:

Several plants and herbs are used in medicine to treat different types of gastrointestinal disorders including peptic ulcer and diarrrhoea. Ulcerative lesions of gastrointestinal tract are one of major side effects associated with the use of non-steroidal anti-inflammatory drugs, alcohol, and stress1. Therefore there is an urgent need to identify novel anti-ulcer agents derived from plant sources. The use of the medicinal plants for curing disease has been documented in history of all civilization.

Tylophoraindica (family: Asclepidaceae) commonly known as Antmul is a twining perennial plant distributed through southern and eastern plant of India2.

There are several plants very effective in treating ulcer / diarrhea, such plants include mermia emerginata3,vernonia cinerea4oroxylum indium vent5. One such plant Tylphoraindica, contain alkalods viz., Tylophorine, tylophorinine, tylophorinidine, sterols, flavanoids, wax, resins and tannins6. the active constituent mention above has reported many biological activities, such as anti inflammatory, anti-cancer, anti-oxidant, anti-asthmatic and anti-microbial activity7, 8, 9.However the literature reveals that no scientific data on anti-ulcer and anti diarrhoea.

ENCLOSURE-II

6.2. Review of Literature:

The plant Tylophoraindica, (family Asclepidaceoe) commonly known as antmul is a twining perennial plant distributed through southern and eastern plant of India in plans, forests and hilly places10. The plant is found growing normally in Uttar Pradesh, Bengal, Assam, Orrisa, Himalayas and sub-himalayas in India. It is a branching climber or shrub that grows up to 1.5 meter leaves or obvate-oblong to ellipstic-oblong, 3-10 cm long and 1.5-7 cm wide11.

Chemical Constituents

The literature survey reveals that the plant contain major chemical constituents TylophorineKaempferol, -amyrin,-sitosetrol, and quercetin, tannins, flavanoids, other major alkaloide like tylophorindine, desmethylthlophorine, desmethyltylophornine and other alkaloids (+) septicine and (+) isotylocerebrine from fresh leaf12.

The literature reveals of Tylophoraindica has been posses diuretic activity13, hepato protective activity (paracetamol induced liver damage)14, immunomodulatory effect15, antiulcer activity (histamine and naproxen induced gastric ulcer)16. However the litrerature reveals that there is no scientific data on anti-ulcer and anti-diarrhoeal. Hence, purpose of safe compound with lesser side effects to treat gastrointestinal disorders by using herbal plants. Tylophoraindica use as herbal drug in Ayurveda traditional medicinal system, hence present study is purpose to investigate the TylophoraIndica leaves for anti-ulcer and anti diarrhoeal activity.

Review of literature till date regarding Tylophoraindica was carried out by referring chemical abstracts, biological abstracts, medicinal and aromatic plant abstracts and other scientific journals.

In view of this the present study is taken up to investigate the anti ulcer and anti diarrhea activity of tylophoraindica so this study is essential and justifiable.

ENCLOSURE-III

3). Objectives of the study:

1)The study is aimed to investigate and validate the anti-diarrhoeal and anti-ulcer activities of pharmacological methods of evaluation.

2)In view of this, the leaves of the Tylophoraindica have been selected for the present study.

ENCLOSURE-IV

7. Material & methods:

7.1 Source of data:

Whole work is aimed to generate data from the laboratory i.e. experiments on animals. Albino mice and rats will be used for this purpose.

The experiments, which involves:

1)Extraction of leaves of the Tylophoraindica with suitable solvent(70% alcohol).

2)Phytochemical investigation.

3)Evaluation of 70% alcoholic extract of Tylophoraindica leaves for anti-diarrhoeal and anti-ulcer potential by employing experimentally induced ulcer and diarrhoea models.

ENCLOSURE-V

7.2Methods of collection of data:

a)Chemical studies:

The leaves and Tylophoraindica were dried in shade and processed to a coarse powder. The powder is used for extraction purpose by using different solvents.

Pharmacological studies:

1)Determination of acute toxicity17:

Fixed dose method (OECD guide line No. 420) of CPCSEA will be followed to carry out LD50 of the extracts. For this purpose albino mice of either sex (20-25gm) will be used.

2)Evaluation of the extract for antidiarrhoel and antiulcer activities by different experimentally induced diarrhoea and ulcer models. The experimental models (screening models) will be used in the study are outlined as below.

Anti-diarrhoeal activity:

a)Castor-oil induced diarrhoea18:

  1. Inclusion criteria: In the present study only healthy albino rats of either sex (wistar strain), 150-200g body weight are selected

Any animals not satisfying above criteria will be excluded.

  1. Four groups of rats containing six animals each

b)Gastro-Intestinal motility test19.

  1. Albino rats of either sex weighing 15-200gm should be selected
  2. Four groups of rats containing six animals each.

Group-I: Control (0.2ml 2% w/v of gum acacia p.o)

Group-II:Atropine sulphate (5mg/kg. i.m)

Group-III:70% Ethanolic extract (p.o)

.

All the results were subjected for the statically analysis by ANOVA. Followed by student ‘t’ test

Anti-ulcer activity:

a)Aspirin induced ulcer20:

ii)Inclusion criteria: Only healthy albino rats of either sex weighing between 150-200g should be selected

iii)Four groups of rats containing six animals each.

Group I:Control (Aspirin 500mg/kg p.o)

Group II:Standard (Lansoprazole 8mg/kg p.o)

Group III:70% Ethanolic extract (p.o)

The test drugs should be administered orally in 2% gum acacia solutions 45min prior to aspirin treatment

After 4hrs animals were sacrificed and stomach is dissected out for scoring ulcer index.

b)Pylorous ligation induced gastric ulcer21:

i)Inclusion criteria: Only healthy albino rats of either sex weighing between 150-200g should be selected

ii)Four groups of rats containing six animals each.

Group I:Control

Group II:Standard (Ranitidine 50mg/kg)

Group III:70% Ethanolic extract

The drugs were given orally 2hrs prior to pylorus ligation as reported by shay (shay et.al. 1945). 5% w/v Acacia mucilage was used as vehicle at a dose of 5ml/Kg.

The animals were sacrificed 6hrs after pylorus ligation for observation of gastric lesion as described by Gupta (Gupta et.al. 1985).

iii)Now follow up as all the animals will be sacrificed

The data obtained from the above study will be subjected to statistical analysis using one-way ANOVA. Followed by student’s ‘t’ test.

Total duration for the completion of whole project may be eight months

  1. Leaves collection and shade drying:One month
  2. Duration of experimentation :Four months
  3. Literature survey:One and half month
  4. Thesis writing :One and half month

ENCLOSURE-VI

7.3.Does the study require any investigation or interventions to be conducted on patients or other humans or animals? If so, please describe briefly.
