BACKGROUND There has been no dearth of scientific literature that genotoxic agents have a causative effect in the pathogenesis of carcinomas. 7,12 dimethylbenz(a)anthracene (DMBA), which is a potent organ specific carcinogen, has been found to produce mutagenic effects on cells. Annona squamosa has a long history in traditional Indian medicine for being used to treat several diseases including ...

Tyrosinase is a well-known key enzyme in melanin biosynthesis and its inhibitors have become increasingly important because of their potential use as hypopigmenting agents. In the present study, the anti-melanogenic effect of aqueous and ethanolic extracts from Euphorbia characias leaves, stems, and flowers in cell-free and cellular systems was examined. All the extracts showed inhibitory effec...

OBJECTIVE Regarding the anticonvulsant effects of Satureja hortensis (S . hortensis) in Avicenna's book: canon of medicine; the present study was undertaken to evaluate the anti- eplileptic effects of S . hortensis aqueous and ethanolic aerial part extracts. Furthermore, the mechanisms of their anticonvulsant activities were also evaluated. MATERIALS AND METHODS Seizure was induced by Pentyle...

Some plant extracts showed the ability to retard the diffusion of glucose across the dialysis tube. The present study was designed to investigate the effect of aqueous and ethanolic extracts of Teucrium polium (T. polium) on glucose movement across the dialysis tube. The T. polium powder was dissolved in ethanol and distilled water. Then glucose was added to make a final concentration of 0.2 - ...

The present study investigates a concentration-dependent assessment of scavenging property and antioxidant activity in the extracts of Emblica officinalis Gaertn. syn. Phyllanthus emblica L. fruit using various in vitro assays. A correlation of aqueous and ethanolic extract of Emblica fruit along with different known standards for its antioxidative properties was made by performing assays like ...

OBJECTIVE To identify the antihyperglycemic activity of various extracts, petroleum ether (60-80°), chloroform, acetone, ethanol, aqueous and crude aqueous, of the flower buds of Michelia champaca, and to identify the antidiabetic activity of active antihyperglycemic extract. MATERIALS AND METHODS Plant extracts were tested for antihyperglycemic activity in glucose overloaded hyperglycemic ra...

The effects of the aqueous and ethanolic extracts of Ocimum gratissimum (Linn) on the haematological indices and histology of the spleen of adult Wistar rats, as well as its antimicrobial properties were investigated in this study. Ocimum gratissimum (Linn) is widely distributed in tropical and warm temperate regions and is commonly called “fever plant”. Twenty five adult wistar rats with weigh...

Teucrium polium L. (Labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. In this study antimicrobial activity of two crude extracts obtained from Teucrium polium L. was tested against bacterial species. Minimum Inhibitory Concentration (MIC) and Minimum Bactericid...
