A simple medium without blood modified for successful isolation & cultivation of LD bodies.

A simple growth medium for primary isolation and subsequent cultivation of Leishmania donovani promastigotes without using whole blood is described. This medium is modified from Aljeboori's biphasic medium (used originally only for cultivation), containing only beef extract, peptone, sodium chloride, bactoagar and foetal calf serum (FCS). We have modified the medium by adding glucose and ascertaining the pH in the solid phase and by drastically reducing (91%) FCS in the liquid phase. The medium helps in isolation of L. donovani promastigotes from kala-azar patients, in addition to luxurious growth of parasites. The medium is simple, reliable, reproducible and convenient, with minimal interference in using the parasitic cells for immunological, molecular and isoenzyme studies.

A retrospective study on scorpion sting in a pediatric age group in a hospital in Calcutta.

During 1985-1989, in Calcutta Medical College Hospitals, of 152 children of 1-6 year age group admitted with the history of scorpion sting 18 (11.8%) died. Maximum numbers of stings were inflicted in the fingers. Important clinical features recorded were circulatory failure, breathlessness, profuse sweating, vomiting, local oedema and convulsion.
