Abstract

Alteration in the pattern of heterocysts is observed when suspending ammoniaโ€grown filaments of Anabaena ARM 314 in a medium devoid of combined nitrogen source but supplemented with rifampicin. Paired as well as strings of 3โ€“9 heterocysts were noticed. The electrophoretic protein pattern of nonโ€heterocystous, heterocystous and multiple heterocystous filaments revealed that multiple heterocystous filaments are characterized by the presence of two additional protein transients. It is speculated that rifampicin may lead to an alteration in the enzyme system involved in the synthesis of inhibitory substances or, alternatively, to the formation or activation of enzyme systems involved in the sequestering of inhibitory substances.

Tuberculosis chemotherapy involves combination of the drugs isoniazid (INH), rifampicin (RMP) and pyrazinamide (PYR) for a 6-month period. The present work investigated the influence of RMP and PYR on the pharmacokinetic parameters of INH when groups of rats were pre-treated for 21 days with INH alo
