1.  Effect of Selected Antiasthmatic Plant Constituents Against Micro Organism Causing Upper Respiratory Tract Infection 
Ancient Science of Life  2010;29(3):30-32.
Most exacerbations of asthma can be proven to be associated with bacterial infections and there is scientific evidence that frequent respiratory infections particularly bacterial infections provoke asthma attack. Considering these facts different plant extracts and phytoconstituents with proven anti asthmatic property had been selected for screening anti microbial activity in in-vitro models. In the present study, Coleus forskohlii Willd. extract (10% Forskolin), Piper Longum L. Extract (20% Piperine), Adathoda vasica Nees. extract (30% Vasicinone), Curcuma longa L. extract (60% Curcumin) were screened for the antibacterial activity against human pathogens causing upper respiratory infection namely Haemophilus influenzae , Streptococcus pneumoniae , Streptococcus pyrogene and Staphylococcus aureus, by taking Gentamycin, Optochin, Bacitracin and Amoxicillin as reference standards. Except for Adathoda vasica Nees. extract, all the other selected plant extracts exhibited a moderate activity antibacterial activity against selected strains.

2.  A comparative pharmacognostical evaluation of two Artemisia species found in Nilgiris biosphere 
Ancient Science of Life  2007;27(2):7-13.
Artemisia pallens Wall. ex DC commonly known as “Davana” in Kannada and Artemisia abrotanum Linn. known as “Southernwood” (Asteraceae) are aromatic herbs, erect in habit, upto 60 cm tall, leaves are very small, much divided, bluish green. These plants find use in traditional systems of medicine viz., anthelmintic, tonic and antipyretic properties. Since, these species have not been scientifically evaluated; the present study was aimed to bring these plants under a suitable pharmacognostical scheme.

3.  Pharmacological validation of Kantha chendooram for antiulcer activity in modified pylorus ligated (shay) rat model 
Ancient Science of Life  2007;27(2):38-43.
The use of metals and minerals is predominant in siddha system of medicine. As per siddha concept, peptic ulcer is known as Valigunmam, the basic abnormality appears to be the derangement of metabolism in the stomach and duodenum resulting in malfunctioning of the secretory process of gastric mucosa. Chendooram is a group of siddha drugs which is used for anemia, obesity, rheumatic diseases; abdominal tumours etc.During the present study standardized Kantha chendooram was selected and evaluated for its anti-ulcer activity, which could not be attempted by researchers earlier.

4.  STANDARDIZATION OF KANTHA CHENDOORAM 
Ancient Science of Life  2006;26(1-2):89-91.
Siddha is a traditional medical system of India. According to siddha system of medicine, chendooram is a red colour powder generally made of metallic compounds. Mercury is used in the form of rasa chendooram (red oxide of mercury). This paper deals with the standardization of Kantha chendooram. It is a Siddha preparation of 8 ingredients, viz. 1. Purified Lode Stone, 2. Purified Sulphur, 3. Lead wort root powder, 4. Eclipta juice, 5. Lime juice, 6. Milk, 7. Egg albumin, 8. Madar Latex. In this study an attempt was made to standardize Kantha chendooram which has not been attempted by researchers earlier. Standardization of Kantha chendooram was in terms of its organoleptic characters, qualitative identification of phytochemical constituents, metallic quantification and in terms of pharmacognostical standardization.

5.  PHARMACOLOGICAL VALIDATION OF Musa paradisiaca BHASMA FOR ANTIULCER ACTIVITY IN ALBINO RATS – A PRELIMINARY STUDY 
Ancient Science of Life  2006;25(3-4):67-70.
Siddha system of medicine is one of the ancient systems of medicine in India. According to Siddhars, peptic ulcer is known as Valigunmam with its signs and symptoms as detailed in Siddha literature matching modern terminology of peptic ulcer. Bhasma refers to calcinated metals and minerals. During this study the Bhasma of Musa paradisiaca Linn, is prepared and evaluated for its antiulcer effect in albino wistar rats which could not be attempted by researchers earlier.

6.  PURGATIVE AND ANTI-INFLAMMATORY ACTIVITIES OF CASSIA DIDYMOBOTRYA, FRESEN 
Ancient Science of Life  2002;22(1):9-12.
Aqueous and ethanol extracts of cassia didymobotraya were investigated for purgative and anit-inflammatory activities in albino mice and rats, respectively at a dose of 100 mg/kg body weight. Anti-inflammatory activity was screened by 1% carageenan induced paw edema method and purgative activity was screened by the method described by Akah etal, Both the extracts exhibited significant purgative and anti-inflammatory activities, which are comparable to standard drugs, Senna (20mg/kg) and indomethacin (20mg/kg). Ethanol extract showed higher purgative and anti-inflammatory than aqueous extract. The percentage of protection of aqueous, ethanol extracts and indomethacin were found to be 35.29,37.25 and 43.13.

7.  ANTI – TUMOUR EFFECT OF BERBERIS ASIATICA ROXB. EX. DC. ON DALTON'S LYMPHOMA ASCITE 
Ancient Science of Life  1998;17(4):290-299.
Berberis asiatica Roxb. Ex. Dc., non Griff. Belongs to the family berberidaceae commonly occurring in the dry outer Himalaya, Assam etc. Roots along with stem bark s a reputed drug in Ayurvedic medicine contain several alkaloids. 50% Ethaolnic extract of roots reported to posses anti-cancer activity. The present study examines the antitumour effect of ethanolic root extract (BRE) against Dalton's lymphoma ascites tumour cells and solid tumour in swiss albino mice, A significant enhancement of mean survival time of BRE treated tumour bearing mice was found. Oral administration of BRE reduced the solid tumour induced by DLE and restored the altered haematological parameters to normal.

8.  CYTOTOXIC AND ANTI –TUMOUR PROPERTIES OF ETHANOLIC EXTRACT OF BACOPA MONNIERI (L) PENN 
Ancient Science of Life  1998;17(3):228-234.
Bacopa Monnieri (L) penn. Belongs to the family scrophulariaceae is commonly used in Ayurvedic system of medicine to treat various disease. The present stud examines the anti-tumous effect of ethanolic extract of whole plant bacopa monnieri (L) (EEMB) by in vitro short term chemosensitivity and in vivo tumous model test systems. EEBM dose dependently inhibited the proliferation of transformed cell lines significantly. Fifty percent dose on 3 hour exposure to EEBM was 150 μg/ml for Dalton's lymphoma ascites tumour cells (Dla). Oral administration of the EEBM retarded the development of solid tumour and restored the altered hematological parameters near to normal.

9.  ANTI-PYRETIC ACTIVITY OF SOME PLANTS IN FEMALE ALBINO RATS: A PRELIMINARY REPORT 
Ancient Science of Life  1995;14(4):253-257.
Ethanolic extracts of Ailanthus exceisa (AE). Toddalia asiatica (TA) and Araucaria bidwilli (AB) were screened by the anti-pyretic activity in yeast induced hyperthermic test model in the laboratory. Dose of AE (100), TA (60) and AB (30) mg., equivalent of the plant material per kg. Body weight of the extracts were administered orally to the female albino rats. Acute toxicity and preliminary phytochemical screening were conducted for all the extracts. LD 50 values on oral administration of the extracts were found to be AE (1000), AB (350) and TA (250) mg. per kg. body weight respectively. Both the root and aerial part fractions of TA displayed a pronounced anti-pyretic activity comparable to the standard drug paracetamol. AB oleoresin fraction was also found to show anti-pyretic effect. These observations however, confirm the folk-medical practices still prevailing among the tribes.
