A series of novel benzene sulfonamides (previously evaluated as selective cyclooxygenase-2 inhibitors) has been profiled against human carbonic anhydrases I, II, IV and VII in an attempt to observe the manifestation of the well established "tail" approach for designing potent, isoform-selective
Calcium dobesilate ("Doxium", O.M. Laboratories, Geneva) was tested in two high-protein edemas. While at a high dose level it had no effect on burn edema of the ratfoot, it did at a low dose. It greatly reduced (to 26%) acute lymphedema in the rat thigh (although not in the foot). Electron
The purpose of this study was to evaluate the effects of mannitol (Man), dexamethasone (DM), dichloroacetic acid (DCA) and 1,3-butanediol (BD) in reduction of posttraumatic cortical edema following brain deformation injury to rats. Ten minutes prior to fluid percussion injury, each animal received
Chronic effects following repeated exposure to low doses of benzene have been well assessed, whereas few data are available about acute exposure to benzene. We report a case of fatal acute intoxication which occurred aboard a chemical cargo ship. Autopsy findings included blood clots inside the
Three benzene sulfonate compounds, benzene sulfonate, benzene meta-disulfonate, and para-phenol sulfonate, were reported to be present in groundwater sampled from residential wells near a former disposal site. Concentrations ranged from < 0.005 mg/L to 474 mg/L. Acute dermal irritation studies were
With the aim of assessing of dextran-benzene-tetracarboxylate hemoglobin as an oxygen carrier, we studied histological changes in the intestinal loop in anesthetized guinea pig. The intestinal tissue being very sensitive to hypoxia, an innervated loop was vascularly perfused with open-flow during
This study evaluated the effect of Yucca schidigera (YS) extract on the physiological, reproductive, and endocrine indexes of New Zealand White rabbit does. Six-week-old rabbit does were fed a standard diet (control group) or a diet enriched with 5 or 20g of Y powder extract per 100-kg feed mixture
Nineteen new 2-pyrazoline bearing benzenesulfonamide derivatives were synthesized by condensing chalcones with 4-hydrazinonbenzenesulfonamide hydrochloride. Their chemical structures were proved by means of IR, (1)H NMR, (13)C NMR, mass spectroscopic and elemental analyses data. These compounds were
Thirteen new 2-pyrazoline derivatives bearing benzenesulfonamide moiety (2a-m) were synthesized by condensing appropriate chalcones with 4-hydrazinonbenzenesulfonamide hydrochloride and tested for anticancer and anti-inflammatory actions. According to the protocol of the National Cancer Institute
Eight novel 2-pyrazolines (2a-h) were synthesized by the reaction of appropriate chalcones/flavanones with 4-hydrazinonbenzenesulfonamide hydrochloride and tested for anti-inflammatory and anti-cancer activities. Two compounds 2c and 2e showed good anti-inflammatory activity which is comparable to
Plants of the genus Wikstroemia have long been used as traditional medicines to treat diseases like pneumonia, rheumatism, and bronchitis. This study was designed to determine the effect of chamaejasmine, a biflavonoid present in W. dolichantha, on atopic dermatitis (AD)-like skin
The skin exposure to solar irradiation and photoreactive xenobiotics may produce abnormal skin reaction, phototoxicity. Phototoxicity is an acute light-induced response, which occurs when photoreacive chemicals are activated by solar lights and transformed into products cytotoxic against the skin
BACKGROUND
Smoke inhalation injury is the main cause of fatalities for fire victims. Understanding in the pathophysiology of the injury has not been fully explored in recent years. To further explore the pathophysiological mechanism, a dynamic and controllable animal model is necessary.
OBJECTIVE
To
Illicium lanceolatum is a traditional Chinese medicine (TCM) for treating inflammatory diseases. Anti-inflammatory activities of I. lanceolatum stems and leaves were tested using ear edema models induced by dimethyl benzene in mice. Bioassay-guided fractionation of the ethanol extract of I.
The effects of chemical modification with 4-NN-dimethyl amino azo benzene-4'-isothiocyanate on various biological activities of phospholipases A2, NN-XIII-PLA2 from Naja naja naja and VRV-PL-VIIIa from Vipera russelli snake venoms were investigated. Modification of the enzymes resulted in
