The development of new pharmaceutical forms with classical active compounds generates new analytical problems. That is the case of sugar-free sachets of cough-cold products containing acetaminophen, phenylephrine hydrochloride and chlorpheniramine maleate. Two cyanopropyl stationary phases have been employed to tackle the problem. The Discovery cyanopropyl (SUPELCO) column permitted the separat...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

a study was made on the interaction between histon h1 and sodium n-dodecyl sulphate (sds) in the presence of sodium arsenate inside a phosphate buffer of ph 6.4, using spectroscopy and equilibrium dialysis at 27 °c. the binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the wyman binding potential. the binding data hs been analysed in terms of hi...

INTRODUCTION Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing. OBJECTIVE The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency...

The aim of this study was to analyse the genetic basis of excessive ethanol consumption and its relationship with emotional reactivity. The high-ethanol preferring line of rats used is characterized by a: (i) high voluntary consumption of alcohol; (ii) high sensitivity to taste reinforcement (saccharine, quinine); (iii) high locomotor activity in a novel environment; and (iv) low emotional reac...

The coexistence of upper airways disease with chronic obstructive pulmonary disease (COPD) is not well documented. The aim of this research was to assess sino-nasal inflammation in COPD by various tools, and look for the impact on quality of life, relation to smoking, disease severity and systemic inflammation. Current and ex-smokers with COPD (n = 42) and healthy never-smokers (n = 21) were in...

the methanolic leaf extract of thuja occidentalis was evaluated for possible sedative activities in mice. sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (epm) tests at 200mg/kg and 400 mg/kg.  the extract decreased the locomotor activity of mice in hole cross, open field and epm test and showed the remarkable resul...
