BACTERICIDAL ACTIVITY OF RASA SINDOORA

Infectious diseases are the health disorders that are caused by infection causing organisms which use human body for surviving, reproducing and colonizing. These organisms are known as pathogens. Gradually increasing microbial resistance has made it more complicated. Therefore, everyone wants to explore remedies from natural source. Rasa sindoora is a Kupipakva Rasayana which is very popular and is widely used in therapeutics. In vitro evaluation of its bactericidal activity against the strains of some bacteria those are responsible for disease was carried out in microbiology laboratory, SBLD Ayurved Vishwabharti. Agar well diffusion method and disc diffusion methods was followed to assess the bactericidal activity like bacteria Salmonella Sp., Staphylococcus aureus subsp. aureus, Pseudomonas aeruginosa, and Escherichia coli and the zone of inhibition were calculated. Staphylococcus aureus subsp.aureus and Escherichia coli show maximum zone of inhibition result. All the bacteria were found susceptible against samples of Rasa sindoora with different concentration. When Rasa sindoora concentration will be increasing the gradually microbial concentration will be decreasing. After calculation of minimum inhibitory concentration E.Coli Show Maximum susceptibility against Rasa sindoora on concentration of 0.50 mg/ml and Pseudomonas aeruginosa show minimum inhabitation against Rasa sindoora on concentration of 0.50 mg/ml

EVALUATION OF CALCIUM OXIDE NANOPARTICLES TO ENHANCE HEAVY METAL STRESS TOLERANCE IN PLANTS

Heavy metal contamination is a severe environmental problem affecting global food production and safety. Heavy metal stress due to its toxicity, bioaccumulation, and non-biodegradability, it become quite serious in nature. The available strategies for preventing heavy metal contamination are not frequently used because of their inefficient and time- or money-consuming properties. Recent developments in nanotechnology have been made based on ameliorative strategies which have a potential alternative to physic-chemical methods. Under heavy metal stress, the application of calcium oxide nanoparticles (CaO-NPs) significantly boosts plant biomass, anti-oxidative enzyme activities (such as catalase (CAT), ascorbate peroxidase (APX), superoxide dismutase (SOD), and glutathione reductase (GR)), and the level of non-enzymatic antioxidants (ascorbate and glutathione). Additionally, CaO-NPs enhance the gene expression linked to anti-oxidative enzymes. It can be suggested that CaO-NPs could be used as a potential chemical to reduce heavy metal uptake and toxicity in the plants grown under heavy metal contaminated soil. This review provides an overview of plant-CaO-NPs research in increasing heavy metal stress tolerance in plants. View Article DOI: 10.47856/ijaast.2022.v10i01.00

23-28<span style="mso-bidi-font-size: 9.0pt" lang="EN-GB">Present study has shown that differentiated cell types may loose their definitive characteristics and acquire features of another specialized cell type. Young (3 toe stage) and mature (5 toe stage) tadpoles of the frog, Euphylictis cyanophlyctis were employed as experimental animals. Experiments were completed in two phases: in the first part of experiment, lenses were extracted from right eye balls of tadpoles and treated with vitamin A; in the second part of the experiment, meshed lentectomized eye ball tissues were implanted into the pit made on mid lateral position of the tail of young and mature tadpoles and were treated with vitamin A. The results obtained gave clear evidence of plasticity and reprogramming of terminally differentiated ocular tissue into lens, retina and even complete eye. Vitamin A was found to be good model for accelerating the reprogramming of differentiated ocular tissue in anuran frog tadpoles. </span
