Screening and evaluation of ethanolic extract from Casuarina equisetifolia inflorescence on isolated chick rectum, frog rectum and frog rectus abdominus muscle for identification of muscarinic and nicotinic receptor’s action
Authors: Umamaheswar Rao O. , Chinna Eswaraiah M. 
Published: January 2019

The present experiments were undertaken to justify the use of an ethanolic extract from inflorescence of Casuarina equisetifolia, Family: Casuarinaceae, influencing the nicotine responses on isolated chick rectum and frog rectum (Smooth Muscles) and frog rectus abdominus muscle (Skeletal Muscle). The isolated tissues were mounted in organ bath filled with physiological solution and was suitably aerated. After equilibration, responses were taken to different doses of nicotine (log doses) till a ceiling response was obtained. A sub-maximal dose of nicotine was selected and responses to this dose was taken and ensured that there is reproducibility of response. The drum was allowed to move for 1min., different concentrations of extracts into the organ baths were added and allowed to act for 1min without flushing the baths, then the sub-maximal dose of nicotine was added and allowed to act for 1min. this procedure was repeated (without extract) till the original response was obtained. The inference drawn from these experiments, the ethanolic extract of inflorescence of Casuarina equisetifolia antagonised the action of nicotine on isolated chick rectum, relaxed the effect of nicotine on frog rectum and it potentiated the effect of nicotine on frog rectus abdominus muscle. The nicotine receptors of rectus abdominus is activated, perhaps by the prevention of hydrolysis of acetylcholine by the extract. Based on the results obtained from the isolated chick rectum the ethanolic extract is having antinicotinic activity and it may act on the nicotinic acetylcholine receptors (nAChRs) as well as muscarinic acetylcholine receptors (mAChRs) on other isolated tissues. The extract might contain ganglionic blocking activity or non-specific activity or membrane stabilising activity also.

Phytochemical evaluation and in vitro antioxidant studies of selected species of Gomphostemma Wall. ex Benth. from Western Ghats
Authors: Sajitha M. K , Thoppil J. E. 
Published: January 2019

Plants are a rich source of bioactive compounds and have played a vital role in traditional medicine. Plant derived compounds are proved to have less side effects as compared to synthetic compounds. However, a truncated history on the contribution of plants to medicine together with lack of validation of plant derived components have led to massive research in phytochemistry and allied fields. Present study was intended to identify as well as to assess and compare different phytochemicals and antioxidant potential of selected taxa of Gomphostemma endemic to Western Ghats. Methanolic extracts of aerial parts of Gomphostemma heyneanum var. heyneanum, Gomphostemma heyneanum var. rottleri and Gomphostemma eriocarpum were subjected to preliminary phytochemical screening. Quantitative estimation of phenols and flavonoids was done with Folin-Ciocalteu method and modified Aluminium chloride method respectively. Antioxidant potential was examined by DPPH assay, Hydroxyl radical scavenging assay and Reducing power activity. Preliminary screening indicated the presence of many secondary metabolites like phenols, flavonoids, alkaloids, terpenoids and steroids. Results of quantitative estimation revealed that G. heyneanum var. heyneanum has the highest concentration of phenols and flavonoids. Antioxidant potential determined in terms of inhibition percentage also displayed that Gomphostemma species have significant radical scavenging activity. The antioxidant potential exhibited by the plant species may be attributed to their phenol and flavonoid content.

Published: January 2019

The mosquito-borne arbovirus Zika virus (positive-stranded RNA virus, ZIKV, Flavivirus, Flaviviridae), has caused an outbreak imposing by its extent and quick spread. This became the focus of a current pandemic and public health crisis all around the world because of the incessant geographic growth of both the virus and its mosquito vectors; it is often misdiagnosed with other disease like yellow fever, west nile, dengue and chikungunya because of same clinical manifestation. After unprecedented huge scale outbreak of ZIKV in Pacific, Micronesian island of Yap in 2007, though ZIKV infections are in general sporadic cases or causing mild self-limiting illness, harsh symptoms have been explained including neurological disorders, autoimmune disorder, fetal anomalies, impaired central nervous system of the fetus, microcephaly in newborns, meningoencephalitis, myelitis and Guillain Barre´Syndrome supposed to be linked with ZIKV. The virus is transmitted mainly by a mosquito Aedes aegypti, whereas, other routes of viral broadcast includes monkey bite, coitus and body fluids such as semen, blood and saliva which needs further corroboration. The relationship between these conditions with ZIKV infection is still not established and is under assessment. Till now there is no vaccine or specific antiviral against ZIKV, therefore the public health authority focuses on preventing infection, mainly in pregnant women and virus transmitted area. WHO and other health officials are working on the expansion of new projects and mosquito control techniques to manage up with infection as there is very fewer literature present on the pathogenesis of the ZIKV to help understand the clinical disease spectrum and target treatments to decrease or stop infection. The future status of ZIKV dispersal to other parts of the world is still unknown. The present review emphasizes various features of ZIKV and its history, epidemiology, transmission, clinical manifestations, progress and advances in developing effective diagnostics, vaccines and drugs/therapeutics along with accepting suitable avoidance and control strategies to undertake this deadly emerging disease.

Authors: Gupta Ankita , Dubey Shaifali , Mishra Mayuri 
Published: January 2019

Dendrimers are novel three dimensional, hyperbranched globular nano polymeric architectures. Attractive features like nanoscopic size, narrow polydispersity index and excellent control over molecular structure afford dendrimers with ideal drug delivery ability through encapsulating drugs in their interior or covalently conjugating drugs on their surfaces. The adaptable surface functionalization ability enables covalent conjugation of various targeting molecules onto the surface of dendrimers, thereby allowing for generation of various multifunctional nanodevices for targeted drug delivery applications. Drug delivery researchers are especially enthusiastic about possible utility of dendrimers as drug delivery tool. However, to get the maximum benefits of these novel class macromolecules, a research by collaboration is very much essential. Finally, it is one of the youngest and exciting fields of polymer researches where all branches of science can take part and hence, deserves more intensive attention.

Cardiovascular disease (CVD) is a disorder of heart and blood vessels. CVD is one of the major causes of deaths in India, which contributed around 30 to 40%. The aim of the study was to study the prescribing pattern of drugs, identification of drug related problems and therapeutic intervention in CVD patients. A hospital based prospective and observational study was carried out for a period of nine months in a south Indian tertiary care hospital. Among 120 selected patients, 79 were male (65.83%) and 41 were female (34.16%), more number of patients (35) were between the age group of 55-64 (29.16%) of which 27 were males & 8 were females, and very less number of patients (6) were between the age group 85-94 (5%) of which all the 6 were male. Hypertension is the most commonest and dominant disorder, which affected 47(39.16%) patients, in which 30 were male (25%) and 17 were female (14.16%). Most common risk factor is HTN followed with smoking and diabetes of 45 patients (37.5%). The most often prescribed pattern adopted in CVD is Dual therapy, it is most frequently used therapy 50 (41.66%) and quadruple therapy is less frequently 6(6.5%) used. The diuretics and calcium channel blocker combination were maximally prescribed class of drugs as a dual therapy. A total of 47 drug-drug interactions were found, among 12 were major, 15 were moderate and 20 were minor interactions. Clinical pharmacist has intervened with the help of other health care professionals in order to reduce the risk factor and minimise the drug-drug interactions. The study provides the benefits of presence of clinical pharmacist in a hospital setting, in order to prevent the medication related errors and provide the expertise pharmacotherapy opinion in CVD patients, which improves the patient compliance. Hence study justifies a need of active collaboration between clinical pharmacist, physician and other health care professionals for the better management of CVD patients.

Authors: Phuse Shital S. , Khan Zia. H. 
Published: January 2019

RBC membrane can be affected by consumption of bioactive compounds from herbs and medicinal plants. This study aimed to assess hemolytic effect of crude ethyl acetate and acetone extract from Cassia glauca flowers. Both the extracts of Cassia flowers were prepared, using Soxhlet apparatus. RBCs were washed with phosphate buffered saline and resuspended in 0.9% normal saline. These RBCs were added to different concentrations of the extracts and then incubated. After centrifugation, absorbance of the supernatant was determined by UV spectrophotometer at 540 nm. The present work shows that the fractions exhibited anti-hemolytic potential as extracts of Cassia flower showed very less percent of hemolysis when compared to standard quercetin. IC50values were found to be 23.77μg/ml for (CF EA) and 12.50μg/ml for Cassia flower in acetone(CF A)against standard which was found to be 41.75μg/ml. Extracts of Cassia flower exhibited very low hemolytic activity. Hence, it can be considered as safe to human RBCs. In future recommend further in vitro and in vivo studies to evaluate the clinical efficacy of Cassia glauca extracts for treated several diseases.

Authors: Jayaseelan T , Damodaran R , Ganesan S , Mani P 
Published: January 2019

Environmental pollution has been identified as a major problem in the modern world. Dyeing effluents have become a vital source of water pollution. Release of coloured textile effluents is undesirable in the aquatic environment as they reduce light penetration, thereby affecting aquatic life and limits utilization of the water media. In Tirupur, the textile factories discharge millions of litres of untreated effluents into the drains that eventually empty into river, Noyyal. The release of coloured compound into water bodies is undesirable not only because of their impact on photosynthesis of aquatic plants but also due to the carcinogenic nature of these dyes and their breakdown products. The ability of bacterial strains isolated from the dye effluent of textile mill sites. Morphological and biochemical characterization was done to identify isolates and was found to be Pseudomonas spp, Bacillus spp and Serattia spp. The isolated strains were finally identified by 16S rRNA sequence analysis. Bacteria are generally identified by 16S rRNA sequencing. The rRNA is the most conserved (least variable) gene in all cells. They were identified as Pseudomonas aeruginosa, Bacillus amyloliquefaciens and Serattia liquefaciens. The sequences were deposited in GENBANK. The accession numbers were KU041528, KU041530 and KU041531 respectively. The identification was conformed by 16S rRNA sequencing.
