RESUMO
Piper betle leaf commonly known to be a Paan in India is eaten raw and sometimes with a mixture of areca nut. The leaf is consumed usually after a lunch or dinner. Traditionally the leaf is well known for a health benefits and also chewed as a mouth freshener. A wide range of researches on a Piper betle leaf suggest excellent nutritional benefits on the health. The edible leaf is also known for its specialized essential contents. The current research attempt is carried out to extract the essential oil from the leaf of Piper betle L. by a Hydro distillation method (Clevenger method). The research successfully concludes the extraction of oil with its efficacy towards the percentage of oil achieved during an extraction process.
RESUMO
A child with Jervell-Lange Nielsen syndrome is presented from Kolkata. Family study showed that the other family members are suffering from long QT syndrome. The child had frequent syncopal attack and very prolonged QT interval requiring left cardiac sympathetic denervation and beta-blocker therapy as patient could not afford implantable defibrillator and cardiac pacing.

Studies in newborn humans have demonstrated alteration in the lipid, phospholipid and cholesterol content when compared with age-matched control. Membrane bound (Na+ + K+)ATPase activity is found to be significantly increased in jaundiced neonates. Alteration in membrane permeability characteristics in jaundiced neonates causes severe microenvironmental changes in red blood cell profile.

Alteration in the antioxidant defence mechanism of erythrocytes with rise in serum unconjugated bilirubin level in neonates has been observed. The cellular glutathione level was found to be significantly low. The activity of glutathione reductase in erythrocyte increased to combat the cellular loss of reduced glutathione in neonatal jaundice. In plasma fraction the level of glutathione (reduced) was found to be significantly higher with lowering of glutathione reductase level. Glutathione peroxidase was reduced in cellular level whereas an increase was observed in plasma fraction. Gamma glutamyl transpeptidase level was barely detectable in erythrocyte whereas an increase was observed in plasma fraction. In all the cases erythrocyte G-6-PDH activity level was found within normal limits.
