BACKGROUND: Although antibiotic-induced hepatotoxicity is recoverable with mild impairment, and few of them were reported to cause morbidity. Hence, an adjuvant is essential in reducing such incidences. OBJECTIVE: The aim of this study to evaluate the protective effect of ascorbic acid on antibiotic induced liver toxicity using liver slices. METHOD: Fresh liver slices collected from leghorn chicken were incubated with different concentrations of sulfamethoxazole tetracycline and clavulanic acid along with ascorbic acid (200μg/ml) for 2 hours...

Natural compounds have always played a key role in drug discovery. Anthocyanins are secondary metabolites belonging to the flavonoids family responsible for the purple, blue, and red colour of many vegetables and fruits. These phytochemicals have attracted the interest of researchers for their important implications in human health and for their use as natural colorants. Many in vitro and in vivo studies demonstrated the potential effects of anthocyanins and anthocyanins-rich foods in the prevention and/or treatment of diabetes, cancer, and cardiovascular and neurodegenerative diseases...

From ancient times, medicinal plants have been usually utilized to treat many disorders, but today, interest in these herbs is again aroused, because of their fewer side effects and low-cost. In traditional medicine, for many diseases, various medicinal herbs have been suggested so far. Drimia maritime, also named squill, is an important medicinal plant for the treatment of many diseases, especially respiratory diseases. In the current evidence-based study, we conducted a review of the general characteristics, ingredients, administration form, and side effects of squill in traditional medicine...

The research work aims to investigate Schiff bases of Cinnamaldehyde as biologically potent analogs. In the past decade CADD has emerged as a rational approach in drug development so with the help molecular docking approach we planned to perform virtual screening of the designed data set of Schiff bases. This will be helpful to put some light on the drug receptor interactions required for anti-inflammatory activity. For carrying out virtual screening of the developed Schiff base data set, AutoDock 4.0 was used...

The unique nature of microgravity encountered in space provides an opportunity for drug discovery and development that cannot be replicated on Earth. From the production of superior protein crystals to the identification and validation of new drug targets to microarray analyses of transcripts attenuated by microgravity, there are numerous examples which demonstrate the benefit of exploiting the space environment. Moreover, studies conducted on Space Shuttle missions, the International Space Station and other craft have had direct benefit for drug development programmes such as those directed against reducing bone and muscle loss or increasing bone formation...

Atherosclerosis is a chronic arterial disease characterized by vascular inflammation, accumulation of lipids in the arterial wall, and formation and growth of atherosclerotic plaques followed by ischemia. In subclinical atherosclerosis, cholesterol retention in subendothelial cells leads to induction of local inflammation, generation of foam cells and lesion formation, followed by a chain of other pathogenic events. Atherosclerotic progression can frequently be fatal, since plaque rupture may lead to thrombosis and acute events, such as myocardial infarction, stroke and sudden death...

BACKGROUND: Some lactones prevent protein Myb-dependent gene expression. OBJECTIVE: The object is to calculate inhibitors of Myb-brought genetic manifestation. METHOD: Linear quantitative structure-potency relations result expanded, among sesquiterpene lactones of a huge macrocycle variety (pseudoguaianolides, guaianolides, eudesmanolides and germacranolides), to establish which part of the molecules constitutes their pharmacophore, and predict their inhibitory potency on Myb-reliant genetic manifestation, which may result helpful as leads for antileukaemia therapies with a new mechanism of action...

Cardiovascular disease (CAD) remains the leading cause of morbidity and mortality in the western world. Hypolipidemic drugs have long been used for the primary and secondary prevention of heart disease. However, the high frequency of recurrent events in patients despite on hypolipidemic therapy has increased the need for new more targeted therapeutic approaches. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are monoclonal antibodies to the PCSK9 gene and represent a new class of drugs that have been shown to further decrease LDL-C when administered as a monotherapy or in combination with statins...

Herbal medicines have been used by mankind from time immemorial. Moreover, many modern medicines are originated from plant sources. In earlier days, patients were dependent on herbs for treatment and well-being. However, due to advent of industrial revolution and modern science, scenario of treating diseases has changed over a period of time. Majority of patients started preferring allopathy medicines due to their several advantages over herbal medicines. However, due to long term treatment by allopathic medicines for chronic diseases have led to side effects, hence, patients are now drifting back to the traditional medicines...

BACKGROUND: Vitiligo is a pigmentary disorder characterizing by white macules due to loss of melanocytes. Vitiligo affects about 1 to 4% of people around the world. The treatment of vitiligo has a high cost and the long process of treatment in spite of no complete remedy. It has various psychological side-effects such as depression and anxiety affecting the quality of life seriously. Avicenna in his Canon treated these patients over a thousand years ago. This study aimed to introduce some herbal drugs in vitiligo based on the Canon of Avicenna besides the conventional medical treatments...
