Thirty Years of Physico-Chemical Studies

Physico-chemical studies of the Gum Acacia

Gum acacia is a potent drug having diverse pharmacological effects and wide therapeutic potential. It is used in diarrhoea and dysentery, irritations and ulcers of the stomach and intestine. It is also used in haemoptysis, bleeding piles, menorrhagia, leucorrhoea and spermatorrhoea. Keeping in view the high medicinal importance physico-chemical studies of the drug obtained from Dawakhana Tibbiy...

Thirty Years of Extragalactic H Ii Region Studies

I review a small part of the past thirty years of studies of extragalactic H II regions. Comparing a review of available results in 1975 to what we know today, we see a enormous increase in our knowledge of physical conditions and abundances in extragalactic H II regions, chemical evolution of galaxies, and the primordial helium fraction. Manuel Peimbert and Silvia Torres-Peimbert have made pio...

Physico-chemical Studies on Stability of Clopidogrel Tablet Formulations

Clopidogrel bisulphate (anti-coagulant drug) is an enantio-selective chrial drug and needs to be monitored for the active form in tablet formulation. Hence, a stable tablet formulation was developed for clopidogrel using two different disintegrants of LHPC (to match as closely as possible to innovator tablet) and PVPP XL. Tablets were evaluated for stability analysis using validated analytical ...

Cytomorphological and Physico-chemical Studies of Sida Rhombifolia

Objective: To investigate the cytomorphological and physico-chemical characteristics of Sida rhombifolia. Methods: Fresh leaves, stems and roots were studied for microscopical characters and dried powder of leaves, stems and roots were subjected to physico-chemical analysis using standard methods. Results: The detail microscopy of leaf revealed the presence of paracytic stomata, unicellular cov...
