Spontaneous Vulvar Hematoma in Labor: A Rare Presentation.

Vulvar hematoma during pregnancy is a rare event. Usually they develop due to trauma post-delivery. Rarely such hematomas appear spontaneously intrapartum without any underlying cause.

Biosorption of Pb and Zn by Non-Living Biomass of Spirulina sp.

Removal of heavy metals (Pb(2+), Zn(2+)) from aqueous solution by dried biomass of Spirulina sp. was investigated. Spirulina rapidly adsorbed appreciable amount of lead and zinc from the aqueous solutions within 15 min of initial contact with the metal solution and exhibited high sequestration of lead and zinc at low equilibrium concentrations.
