Ocimum sanctum described as a sacred and medicinal plant in ancient literature, commonly known as Tulsi is derived from ‘Sanskrit,’ which means “the incomparable one.” This plant belongs to the family Lamiaceae which is native throughout the old world tropics and cultivated for religious and medicinal purposes. Several medicinal properties have been attributed to the plant not only in Ayurveda and Siddha but also in Greek, Roman, and Unani. It is widely known across South Asia as a medicinal plant and an herbal tea. Medicinal properties of Tulsi (Ocimum sanctum Linn.) are known for a thousand years to various civilizations of the world. This medicinal herb is considered as a sacred plant by the Hindus in the Indian subcontinent. Scientific explorations of traditional belief of medicinal properties of Tulsi have got momentum mostly after the middle of the 20th century. The wide numbers of phytochemical constituents have been isolated from the plant, e.g., aesculetin, orientin, vallinin, eugenol, alkaloids and is proved to have the potential for medical effects like...

A survey was carried out from 2005 to 2010 to invent the invasive alien plant species and their economic uses in urban and adjoining rural areas of Uttarpara, Hooghly district, West Bengal. The study revealed the occurrence of 103 alien angiospermic plant species under 32 families, of which four families (Araceae, Poaceae, Cyperaceae, Pontederiaceae) are monocots. Dicot family Fabaceae dominated with 20 plant species, followed by Asteraceae with 17, Amaranthaceae with 8, Solanaceae with 7, Euphorbiaceae with 5, and then other families. Rise in number of alien species was evidenced in year-wise quadrat studies, screening 11 most invasive species namely Parthenium hysterophorus, Eupatorium odoratum, Ageratum conyzoides, A. haustonianum, Chromolaena odorata, Cassia sophera, Leucaena leucocephala, Alternanthera sessilis, Amaranthus spinosus, Lantana camara and tree, Trema orientralis distributed within Asteraceae (5 taxa), Fabaceae (2 taxa), Amaranthaceae (2 taxa), Verbenaceae (1 taxon) and Ulmaceae (1 taxon). Remarkably, the alien species have been used in diverse economic and commercial purposes by local village folks, showing the use of nearly 49% plants in local health-care...

The Characean alga, Chara zeylanica was experimentally exposed to Cadmium ion concentrations ranging from 1, 3, 5, 7 and 10 ppb for 7 days. The ultrastructural studies and TEM X-ray microanalysis were performed on the alga exposed to 10 ppb cadmium ion concentration after 7 days of the treatment period. A fine structural examination of the cells revealed that in Cd-treated cells, the cell wall showed the absence of undulating layers, more compactness in their arrangement and much lesser in thickness than the control cells. TEM studies showed striking changes in the plastids of treated algae. They were completely devoid of starch grains. The cell organelles were lacking in the cytoplasm, but it showed the presence of several myelin-like...

Endodontic irrigating solution used in root canal treatment in dental specialty is to eliminate root canal pathogens in necrotic pulp tissues. A microorganism like Staphylococcus aureus, Candida albicans, Enterococcus faecalis were commonly seen pathogens in necrotic pulp tissues. Commonly used root canal irrigating solutions to kill bacteria’s in the dental root canal are hydrogen peroxide (H2O2), chlorhexidine (CHX) and sodium hypochlorite (NaOCl). These root canal irrigating solutions has detrimental effects on the tissues underlying tooth (periradicular tissues) and affects post-operative healing. NaOCl has tissue toxicity and inhibits phagocytosis. Chlorhexidine inhibits protein synthesis in periodontal ligament cells. CHX and NaOCl exhibit an inflammatory effect in mitochondrial activity in human periodontal cells. Natural products are in great demand for their extensive biological properties and their bioactive molecules. Nontoxic Piper betel leaves extract obtained by methanolic extraction method of 500 mg/ml was tested against Staphylococcus aureus and Candida albicans which are commonly associated with root canal treatment and in failure cases using well agar diffusion method. The result shows piper betel leaves...
