BACKGROUND The genus Camellia, belonging to the family Theaceae, is economically important group in flowering plants. Frequent interspecific hybridization together with polyploidization has made them become taxonomically "difficult taxa". The DNA content is often used to measure genome size variation and has largely advanced our understanding of plant evolution and genome variation. The goals o...

The ELISA-inhibition test using Clonorchis sinensis specific monoclonal antibody (CsHyb 0605-23) for diagnosis of clonorchiasis was carried out. It demonstrated sensitivity and high specificity in comparison with the conventional ELISA.

Tea, a beverage produced by steeping processed top leaves and buds of the tea plant in freshly boiled water, originated in China 2700 BC, but its medicinal properties were know much before that. China was the first country to cultivate tea. In Japan the cultivation began about 200 AD. The use of tea later spread to the other Asian countries. Tea cultivation in India was suggested as early as 17...

Tea plants (Camellia sinensis) are well known for their ability to accumulate high concentrations of aluminium (Al). Aluminium distribution in tea leaves has been previously estimated on a qualitative basis using energy dispersive X-ray microanalysis (EDXMA). However, no comprehensive studies have been carried out to quantitatively determine the distribution of Al, especially in young leaves wh...

Effect of aqueous extracts of Ocimum sanctum and Camellia sinensis on restraint stress-induced oxidative damage in the central nervous system (CNS) of R. norvegicus were evaluated in terms of lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). Restraint stress was used for 3h/day for 6 days consecutively, caused a significant elevation in LPO and ...
