Résumé
Chronic administration of phenytoin has been associated to have a number of adverse effects. Falling serum folate levels is one such most often reported adverse drug sequelae of long term phenytoin usage. Folates administered at pharmacological doses, on the other hand, have been blamed for a decrease in the serum concentration of phenytoin, severe enough to precipitate seizures. This review substantiated with references from various studies focuses on the folic acidphenytoin interaction and discusses the feasibility of using folate supplements to avoid such inadvertent drug sequelae in epileptic patients kept on chronic treatment with phenytoin.
Résumé
Protein A linked latex antisera (PALLAS) test was used for detection of B. mori infectious flacherie virus (BmIFV) in silkworms. The test was found superior to direct latex agglutination (DLA) test for detection of BmIFV in infected larval and faecal matter extracts and purified preparations. Latex beads sensitized with anti-BmIFV IgG were able to detect up to 75 ng/ml BmIFV in PALLAS test and 300 ng/ml in DLA test. BmIFV was detected in diluted extracts of infected larvae (up to 1:200) and their faecal matter (up to 1:500). BmIFV progressive infection was detected at 12 and 24 hr of post infection in PALLAS and DLA tests, respectively in both larval and faecal matter extracts. PALLAS tests provides a simple, specific and highly sensitive test for detection of infectious flacherie virus.
