New era is an era of novel drug delivery systems. Pediatric, Geriatric and bed ridden patients have difficulties in swallowing tablets. The purpose of the present study was to develop and characterize mouth dissolving tablets of Levocetrizine Hydrochloride by using direct compression technique. Formulations were designed by factorial design technique. Sodium starch glycolate, Crospovidone and C...

The effect of moderate exercise on jejunal absorption was examined in seven healthy subjects using a triple lumen perfusion technique. Moderate exercise on a bicycle ergometer significantly reduced net absorption of water from 32.0 (4.0) to 16.2 (6.1) ml/30 cm/50 min (p less than 0.02), sodium from 2.4 (0.4) to 0.5 (0.9) mmol/30 cm/50 cm (p less than 0.05), chloride from 2.0 (0.4) to 0.3 (0.7) ...

It was assumed that the enlarged caecum and the accumulation of semiliquid contents in germfree rats is accompanied by changes in sodium absorption. Transepithelial sodium fluxes were studied under Ussing chamber conditions across epithelial sheets of the caecum and colon of germfree (GF) and specific-pathogen free (SPF) rats. Net sodium transport was highest in the proximal colon and in the pr...

Dysregulation of gallbladder ion and water absorption and/or secretion has been linked to cholesterol crystal and gallstone formation. We have recently demonstrated that obese, leptin-deficient (Lep(ob)) mice have enlarged gallbladder volumes and decreased gallbladder contractility and that leptin administration to these mice normalizes gallbladder function. However, the effect of leptin on gal...

Steady-state rates of potassium ion and sodium ion absorption by excised barley roots accompanied by various anions were compared with the rates of anion absorption and the concomitant H(+) and base release by the roots. The cation absorption rates were found to be independent of the identities, concentrations, and rates of absorption of the anions of the external solution, including bicarbonat...

Optimal growth of euhalophytes requires moderate concentrations of salt and, in dicotyledons, is associated with succulence and accumulation of Na(+) in plant tissues. However, reports of salt-stimulated growth in monocotyledons are rare. Relative growth rate (RGR), biomass accumulation, and water content were studied in Sporobolus virginicus (Poaceae), a C(4) chloridoid grass, grown hydroponic...

Roughly 80% of Ultraluminous Infrared Galaxies (ULIRGs) show blue shifted absorption in the resonance lines of neutral sodium, indicating that cool winds are common in such objects, as shown by Rupke et al and by Martin. The neutral sodium (NaI) columns indicated by these absorption lines are ∼ 10 − 3 × 10 cm, while the bolometric luminosity varies by a factor of only four. We show that the gas...
