Passive anaphylaxis induced in the rat hind paw and peritoneal cavity with rat serum containing immunoglobulin E antibody was inhibited by N-(2-oxo-3,5,7-cycloheptatrien-1-yl)-aminooxoacetic acid ethyl ester (AY-25,674). In contrast with disodium cromoglycate (DSCG), AY-25,674 was orally active.
The purpose of this study was to investigate the antimicrobial activity and mechanisms of Nα-lauroyl arginate ethyl ester (LAE) against Penicillium digitatum and Pectobacterium carotovorum subsp. carotovorum. The minim inhibitory concentrations of LAE against P. digitatum and P. carotovorum were
The charge transfer (CT) probe ethyl ester of N,N-dimethylamino naphthyl acrylic acid (EDMANA) bound to Human Serum Albumin (HSA) serves as an efficient reporter of the polarity and conformational changes of protein in aqueous buffer (Tris-HCl buffer, pH=7.03) and in presence of denaturant, quencher
The anticancer efficacy of the new anticancer tripeptide, L-proline-m-bis (2-chloroethyl) amino-L-phenylalanyl-L-norvaline ethyl ester hydrochloride (MF13), was investigated in mice. MF13 showed a therapeutic effect in liquid tumors and induced complete remission even in late stage malignancies.
Ethanol diffuses rapidly into saliva during the drinking, and immediately after its salivary concentration is temporarily much higher than in plasma. Within 30 minutes, salivary ethanol concentration equilibrates with the plasma level, thus suggesting that ethanol easily penetrates the whole body,
The purpose of this study was to evaluate complexes of vinpocetine (VIN), a poorly water-soluble base type drug, with hydroxypropyl-beta-cyclodextrin (HP-beta-CD) in aqueous environment and in solid state, with or without citric acid (CA) as an acidifier of the complexation medium. The apparent
Two new retinoic acid esters and retinamides synthesized in China, N-(4-ethoxycarbophenyl)retinamide (RI) and N-(4-carboxyphenyl)retinamide (RII), significantly inhibited carcinogenesis induced in the epithelium of the forestomach of mice by N-nitrososarcosine ethyl ester. RI also markedly inhibited
Proteolytic activity was studied in human saliva, gingiva and in other tissues of oral cavity by means of hydrolysis of N-alpha-benzoyl-L-arginine ethyl ester (BAEE), protamine and hemoglobin. Alkaline proteinases were mainly observed in gingiva, leukocytes and in a precipitate of mixed saliva. Acid
We immortalized oral keratinocytes by transfection with recombinant human papillomavirus type 16 (HPV-16) DNA and established two cell lines, human oral keratinocytes-16A (HOK-16A) and -16B (HOK-16B). These cell lines were morphologically different from the normal counterpart, contained HPV-16 DNA
Spinal cord injury (SCI) is a cause of paralysis. Although some strategies have been proposed to palliate the severity of this condition, so far no effective therapies have been found to reverse it. Recently, we have shown that acute transplantation of ependymal stem/progenitor cells (epSPCs), which
There is an expectation that ocular inserts, regardless of the nature of the polymer, will faithfully reduce systemic drug absorption. This may not necessarily be so, however, since not all polymers would release drug at the same rate and to the same extent. The objective of the present study was to
OBJECTIVE
This study is to assess the antibacterial activity of omega-6, -7, -9 (n-6, n-7, n-9) fatty acids against various oral microorganisms.
METHODS
The n-6, n-7, n-9 fatty acids, such as gamma-linoleic acid (GLA), linoleic acid (LA), arachidonic acid (ARA), palmitoleic acid (PA), and oleic acid
We have evaluated the efficacy of 13 analogues of retinoic acid (retinoids) in producing in vivo feathers on the normally scaly foot integument (ptilopody) of the chick embryo. The retinoids were dissolved in dimethylsulfoxide and injected at doses from 1.25-250 micrograms into the amniotic cavity
An alpha-chymotrypsin-like enzyme was isolated from mast cells of the rat peritoneal cavity by extraction with 0.8 M potassium phosphate, 2 per cent protamine sulfate followed by affinity chromatography on hen ovoinhibitor-agarose and adsorption on barium sulfate. This procedure yielded over 9 mg of
The fungus Geotrichum candidum produces two lipase isoenzymes, GCL I and GCL II, with distinct differences in substrate specificity despite their 86% identical primary structure. GCL I prefers ester substrates with long-chain cis (delta-9) unsaturated fatty acid moieties, whereas GCL II also accepts
