Choice of a dissolution medium is an important and critical variant for drug dissolution testing. The reported choices range from a simple solvent (water) to complex solutions, often drug and/or product dependent. However, making a choice is not so simple or straightforward, but confusing and often scientifically or logically not convincing or valid. This article provides a discussion in this r...

Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...

Axenic shoot culture of Mentha arvensis was established from young shoots of plants cultivated in a field. In the shoots cultured on Murashige-Skoog solid and liquid media for 3-4 weeks, pulegone was the main constituent in both cases, and the content of pulegone in liquid medium was much more than that on solid medium. The shoots cultured in the dark for 3 weeks produced only pulegone. However...

The aim of the method described in the present paper is to maintain tissues in a condition of uninterrupted growth in a medium which does not deteriorate spontaneously. This simple idea has doubtless occurred to many experimenters, but great technical difficulties have so far prevented the development on this principle of a method of cultivating tissues. The problem consists of giving the cells...
