In a search for plant extracts with potent antimicrobial activity, turmeric (Curcuma longa) was extracted to get volatile oil and total curcuminoids .Further total curcuminoids portion was isolated by column chromatography to get curcumin , bisdemethoxycurcumin and demethoxycurcumin. The isolated curcuminoids were identified and characterized by melting point, thin layer chromatography, infra r...

BACKGROUND Edible plants such as Cratoxylum formosum (Jack) Dyer, Curcumin longa Lin, Momordica charantia Lin and Moringa oleifera Lam have long been believed in Thai culture to relieve ulcers and the symptoms of liver disease. However, little is known about their anti-liver cancer properties and antiviral activity against hepatitis B virus (HBV). The aim of this study was to investigate the an...

1. Exposure of Astasia longa to oxygen+ carbon dioxide (95: 5) at atmospheric pressure leads to an inhibition of growth rate and of respiration. Growth resumes at the normal rate as soon as the oxygenation is discontinued, but respiration recovers more slowly. 2. Mitochondria prepared from cells exposed to oxygen + carbon dioxide (95: 5) during growth have considerably decreased activities of s...

Curcumin [1, 7-bis (4-hydroxy-3-methoxyphenyl)-1, 6 heptadiene-3, 5-dione] is an orange-yellow component of turmeric (Curcuma longa), a spice often found in curry powder. It is known to have a variety of biologic and pharmacologic activities, including anti-inflammatory, anti-oxidant, and anticarcinogenic potential. It is a potent inhibitor of cytochrome P450 with capacity to simultaneously ind...

It was investigated the efficiency of two extracts of plants and one fraction of their properties against the local effects of bothropic envenomation. Bothrops alternatus venom (1.25μg) diluted in 100μl of sterile saline solution was inoculated (intradermally) into the shaved dorsal back skin of 30 New Zealand rabbits. The animals were divided in six groups receiving the following treatments: g...

The Nicodrilus genus is not accepted in the nomenclature according to ICZN; Aporrectodea term is used. However, according to Bouché, Aporrectodea and Allolobophora genera are not homogeneous and are supposed as polyphyletic genera. The aim is to study the phylogenetic structure of Aporrectodea genus in order to verify its cladistic nature and its taxonomical validity. In this work, five species...

The intraluminal filament model of middle cerebral artery occlusion (MCAO) in mice and rats has been plagued by inconsistency, owing in part to the multitude of variables requiring control. In this study we investigated the impact of several major variables on survival rate, lesion volume, neurological scores, cerebral blood flow (CBF) and body weight including filament width, time after reperf...

Background: Different treatment and protective approaches for radiation-induced oral mucositis have been practiced and have varieties of success. Of which, radioprotective agents, synthetic or natural, have been of great interest for researchers. This study aims to evaluate the effect of curcuma longa topical gel as a herbal production on mucositis induced by radiation therapy of head and neck ...

Root canal treatment aims to remove vital and necrotic tissue, microorganisms, their products from the root canal. In this case, chemical endodontic irrigants such as NaOCl Chlorhexidine (CHX) are required. Unfortunately, both have side effects. Twenty percent of C. longa rhizome extract may be a potential alternative due its antibacterial activity ability dissolve smear layer. However, it cont...
