The induction of apoptosis by Piper betel leaf extracts during 7, 12 dimethylbenz [a] anthracene (DMBA) induced hamster buccal pouch (HBP) carcinoma was studied in male Syrian hamsters using DNA fragmentation and the apoptosis-associated proteins, tissue transglutaminase (tTG) and Bcl-2. Hamsters were divided into four groups of six animals each. Animals in group 1 were painted with a 0.5% solu...

ion of a hydrogen atom from poly unsaturated fatty acids (PUFA); the hydroxyl radical is capable of starting this reaction sequence [4, 5]. While Piper species are reported to have wide spectrum of biological activity but its antioxidant potential has not been established so far, making it important and interesting to analyze the antioxidant potential of Piper betle leaf extract in the present ...

The antifungal effect of 10 plant extracts viz., Thevetia peruviana, Ocimum basilicum, Piper betel, Murraya koenigii, Chrysanthemum coronarium, Polyalthia longifolia, Catharanthus roseus, Pelargonium graveolens, Moringa officinalis and Lawsonia inermis were evaluated by poisoned food technique against Rhizoctonia solani Kuhn, the causal organism of sore shin disease of tobacco. Among all the pl...

OBJECTIVE To examine the anti-bacterial activity of leaf extracts of Morus alba L. (Moraceae) and Piper betel L. (Piperaceae), and seed extracts of Bombax ceiba L. (Borabacaceae). METHODS We have partially purified plant extracts by solvent extraction method, and evaluated the effect of individual fractions on bacterial growth using Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aerug...

Natural infection of Cucumber mosaic virus (CMV) in Indian long pepper (Piper longum L.) and betel vine (Piper betle L.) was detected by reverse transcription polymerase chain reaction (RT-PCR). The coat protein gene sequences of CMV infecting these hosts were amplified. The resulting amplicons were cloned and sequenced. In both the cases coat protein gene consisted of 657 nucleotides, potentia...

A study was conducted in Intercropping at Betel Research Station, to evaluate alternative types of supporting materials for betel (Piper betle L.) cultivation. Coir ropes were the most suitable supporting material to achieve higher yield and quality betel. The durability of coir ropes was high in comparison to other supporting materials and the use of coir ropes as a supporting material was the...

© 2000 Canadian Medical Association or its licensors Chewing betel quid or the combination of chewing betel quid and smoking cigarettes is associated with an increased risk of oral squamous cell carcinoma. The composition of betel quid varies with geographic location. In Taiwan betel quid is composed of areca nut (Areca catechu, an Asian tropical palm), slaked lime, and the inflorescence or lea...

Aqueous and methanol extract of the leaves of Terminalia catappa L., Manilkara zapota L. and Piper betel L. were evaluated for antibacterial activity against 10 Gram positive, 12 Gram negative bacteria and one fungal strain, Candida tropicalis. Piperacillin and gentamicin were used as standards for antibacterial assay, while fluconazole was used as standard for antifungal assay. The three plant...

but we occasionall}7 come across cases where the victims have contracted the habit from the very beginning. We do not know how the people of Calcutta have derived their knowledge of the intoxicating property of a costly drug which has hitherto been only handled by medical men, but facts collected tend to show that they have got it from their Bhagalpore brethren where cocaine has become a social...

The aim of this work was to evaluate the inhibitory activities of methanolic extracts of Artocarpus altilis, Cinnamomum zeylanicum, Piper betel and Artocarpus heterophyllus on Wheat alpha amylase and Baker’s yeast alpha glucosidase at varying concentrations. Diabetes mellitus is a clinical condition characterized by hyperglycaemia in which an elevated amount of glucose circulates in the blood p...
