We report in vitro and in vivo anti-inflammatory activities of a series of copper(II)-lawsone complexes of the general composition [Cu(Law)2(LN)x(H2O)(2-x)]·yH2O; where HLaw = 2-hydroxy-1,4-naphthoquinone, x = 1 when LN = pyridine (1) and 2-aminopyridine (3) and x = 2 when LN = imidazole (2), 3-aminopyridine (4), 4-aminopyridine (5), 3-hydroxypyridine (6), and 3,5-dimethylpyrazole (7). The comp...

The properties of smooth muscle cell hyperpolarization produced by acetylcholine (ACh) were investigated in mesenteric arteries isolated from mice. The resting membrane potential of the smooth muscle cells was about -60 mV. When ACh (10 microM) was applied for 1 min, the membrane hyperpolarized with a peak amplitude of about 5 mV which was reached in about 1 min, following which the potential s...

Mature adipocytes originate from fibroblast-like precursor cells, preadipocytes, which differentiate to obtain the characteristics of adipocytes. Our aim was to investigate how differentiation of human preadipocytes affects the distribution of insulin receptors (IR) and IGF-I receptors (IGF-IR) and other cell characteristics. Preadipocytes were differentiated using indomethacine, dexamethasone,...

1.1 Important aspects on ulcer pathogenesis World-wide, peptic Ulcer disease (PUD) is considered as a common gastrointestinal disorder. It develops as a result of altered balance between offensive and defensive factors. Offensive (aggressive) factors disrupt normal mucosal integrity and allow H+ back diffusion with a subsequent cellular injury. Helicobacter pylori (H. pylori) and nonsteroidal a...

The present investigation highlighted the formulation and release characterization of Ketorolac Tromethamine loaded matrix tablet. Various formulations of tablets were prepared by direct compression method along with Kollidon SR and Hydroxy Propyl Methyl Cellulose (HPMC) as release retardant polymers. Each of the formulated tablets contains 50mg Ketorolac Tromethamine. The evaluation involved p...

Introduction : Peptic ulcer occurs more frequently in men than in women, sex differences are less marked after 45 years of age probably because the incidence of ulcer increases in post menopausal women. The general assumption is that the ulcer differences between sexes are related in some way to sex hormones and that the female sex hormones protect against ulceration. The aim of the this study ...

Health benefit of garlic has been well established for a longtime during the history of mankind. Organosulfur compounds of garlic including δ-glutamyl-S-allyl-L-cysteins and S-allyl-Lcysteine (SAC) sulfoxides are known as major components of bioactivity; however, raw garlic is easy to be converted into bio-inactive form. Thus, many types of garlic extract or preparation with diverse composition...
