Abstract The present work discusses the development of cotton and cotton gauze-based bandage using mahogany. The biological properties of mahogany bark extract have been identified. The 25% concentration of mahogany extract have been treated directly and kept at room temperature for conditioning. Further the antibacterial activity of mahogany-treated samples have been evaluated against wound infecting pathogens (AATCC- 147) Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Serratia marcescens and Staphylococcus aureus. It was found that mahogany has good antibacterial property against wound infecting pathogens.

Keywords: Herbs, Mahogany, Pathogens, Wound contact layer

An Outline of Poisoning at Kadapa (South India) Mohan B.*, Thomas S., Basha S. A., Parveen S., Reddenna L., Kumar E. S. J. Department of Pharm-D, P. Rami Reddy Memorial College of Pharmacy, Kadapa, Andhra Pradesh 516003, India Abstract The epidemiology of poisoning can be studied from different perspectives. Early correct diagnosis and appropriate treatment, conversely, are often lives saving. Therefore, the knowledge of the general pattern of poisoning in a particular region would help in early diagnosis and management of poisoning, which in turn should result in a reduction of morbidity and mortality. Retrospective observational Study was conducted for a period of six months in the general medicine and emergency (ICU) units at Rajiv Gandhi Institute of Medical Sciences (RIMS), Kadapa. In our study we found that the poisoning was due to various products such as paraphenylene diamine (a hair dye), Gammexane, Kerosene, Nail polish, Rat poisons, petrol, etc. There is high incidence of 0.7 came in the vasmol poison. A total of 08 (7.2%) deaths were reported throughout the study period and remaining were shifted to general medicine wards and got discharged after complete recovery and some were absconded, referred to higher institution for better care. Psychological counseling may be helpful in elimination in the poisoning consumptions.

Keywords: epidemiology, poisoning, paraphenylene diamine

Rotenone Beyond Just An Insecticide: A Review Ghosh I.*, Maurya N., Agarwal N. R. Environmental Toxicology and Biochemistry, School of Environmental Science, Jawaharlal Nehru University, New Delhi, India Abstract Pesticides have received the most attention due to their global application and widespread implications on human health. In recent years, both epidemiological and toxicological studies have provided evidence that pesticides have the potential to act as toxicants contributing to the development of pathogenesis such as neuronal degenerations as well as may be utilized to induce signalling for reversal, suppress or prevent carcinogenic progression. Rotenone, an isoflavones naturally found in the roots and stems of several plants, is used as a broad-spectrum pesticide. Surprisingly, being a known toxicant, rotenone is used in organic food farming, based on its label as a natural product. Highly lipophilic, it easily crosses the cellular membrane without depending on a transmembrane protein. Once inside the cell, it accumulates at mitochondrial complex I where it is known to inhibit the transfer of electrons and increases reactive oxygen species (ROS) production, causing oxidative damage to DNA and proteins. More recently, rotenone was also shown to inhibit proteosome activity and catalyze the degradation of ubiquitin tagged proteins which may be implicated in pathogenesis of diseases. Numerous plant derived flavonoids compounds, with mitochondrial electron transport chain interrupter, such as rotenone, are currently used by cancer patients as dietary supplements to complement chemotherapy. Excess generation of ROS and its involvement in down-regulation of cellular proliferation by rotenone may be significant in chemotherapeutic assistance in prolonged treatment of tumourigenesis in future.

Cadmium Toxicity: Oxidative Stress and Organ Dysfunction Nazima B., Manoharan V., Prabu S. M.* Faculty of Science, Department of Zoology, Annamalai University, Annamalai Nagar, Tamil Nadu, India Abstract Due to continued anthropogenic mobilization, cadmium accumulation in the environment causes various health problems because of its diverse toxic effects, extremely lingering biological half life (20–30 years), low rate of excretion from the body and storage predominantly in soft tissue primarily liver and kidney. Cadmium is known to have numerous noxious effects, including nephrotoxicity, hepatoxicity, osteoporosis, cardiovascular toxicity, lung toxicity, and reproductive toxicity. The biologically significant ionic form of cadmium, Cd2+, binds to many bio-molecules and these interactions underlie the toxicity mechanisms of cadmium. Some of the molecules (Mg 2+, Ca 2+) and transition metal ions (e.g., Zn 2+, Cu 2+, Fe 3+/2+) is particularly sensitive to the presence of Cd 2+ because they enclose cationic sites to which the toxic metal can bind. Alterations in reactive oxygen species (ROS) production during chronic exposures are less significant compared to the acute cadmium toxicity probably due to induced adaptation mechanism such as metallothionein and glutathione which in turn diminish cadmium induced oxidative stress. Many low molecular weight antioxidants (ascorbic acid, vitamin E, glutathione, Flavonoids) and other antioxidants are capable of chelating cadmium ions reducing their catalytic activity to form ROS. This mini review focused on direct evidence on cadmium induced ROS production, how different organ system responds to cadmium stress and pathological outcomes. For the treatment of cadmium intoxications a therapy with chelating agents has been applied. A better understanding of cadmium toxicity to tackle the environmental challenges lying ahead thus requires properly designed studies implementing biologically relevant cadmium concentrations on different cell types and use of these data in a theoretical framework integrating all cellular aspects of cadmium effects.
