The effects of acetylsalicylic acid （ASA）, CaCl2, and ASA ＋ CaCl2 on the photosynthetic apparatus and antioxidant enzyme activities were investigated in chrysanthemum Jinba （a cut flower cultivar） under low temperature stress with low light （TL stress）（16/12℃, day/night, PFD 100 μmol m^-2 s-1）. The results showed that under TL stress, the net photosynthesis rate （Pn）, carboxylation efficiency （CE）, apparent quantum yield （AQY）, maximal photochemical efficiency （Fv/Fm） of PSII, quantum yield of PSII electron transport （ФPSII）, and photochemical quenching （qP） of the chrysanthemum leaves in all treatments were significantly decreased, but the decreases were alleviated by ASA, CaCl2, and ASA ＋ CaCl2 treatments compared with the controls. The alleviating effect of ASA ＋ CaCI2 was better than either ASA or CaCl2 single treatment. Moreover, the ASA ＋ CaCl2 treatment highly improved the chlorophyll content, relatively improved the number and size of chloroplast and starch grain in the leaves of chrysanthemum plants compared with ASA and CaCl2 treatments. It was indicated that ASA and/or CaCI2 could regulate the photosynthetic functions in the leaves of chrysanthemum plants to enhance the resistance against TL stress. On the other hand, reduction in relative conductance rate implied that ASA and/ or CaCl2 could protect from membrane injury in leaves of chrysanthemum plants. The activities of SOD, POD, and CAT in the treated leaves of chrysanthemum were increased as compared with the controls. It was suggested that ASA and/or CaCl2 had positive regulation effects on the defence enzyme activities in chrysanthemum leaves which could protect the photosynthetic apparatus to a certain degree under the TL stress. In brief, the treatment of ASA together with CaCl2 was better for chrysanthemum plants to adapt TL stress than single ASA or CaCl2 treatments.

In some experiments, organs were treated with ASA for 48 h and then transferred either to control media alone or control media containing 10 μmol/L prostaglandin E2 （PGE2） for a further 5 d. Fetal kidneys were additionally obtained from prostaglandin synthase 2 homozygous null or heterozygous （PTGS2-/- and PTGS2-/＋） embryos and grown in culture.

Addition of 10 μmol/L PGE2 to culture media after exposure to 0.2 mg/mL ASA for 48 h resulted in a return of growth area to control levels. Application of control media alone after cessation of ASA exposure showed no benefit on kidney growth. Despite the apparent recovery of growth area with 10 μmol/L PGE2, no obvious renal tubular structures were formed. The number of epithelial tips generated after 48 h exposure to ASA was reduced by 40% （0.2 mg/mL; P 〈 0.05） and 47% （0.4 mg/mL; P 〈 0.01）.

Type 2 diabetes mellitus and its complications are associated with oxidative stress and the depletion of antioxidant defenses. The influence of acetylsalicylic acid on reversing the decrease in antioxidants, insulin resistance, glucose homeostasis, and inflammatory cascade can help prevent diabetes complications. Purpose: The aim of the study was to evaluate the effect of acetylsalicylic acid on the antioxidant enzymatic system in patients with diabetes. Methods: A randomized, double-blind, placebo-controlled clinical trial was carried out in 21 patients of both sexes with Type 2 diabetes for less than five years at the time of diagnosis, without pharmacological treatment, and randomly selected. acetylsalicylic acid (300 mg) was administered orally for three months to the study group (n = 11) compared to the placebo control group (n = 10). Before and after the intervention, anthropometric and metabolic measurements were taken, fasting plasma glucose, glycated hemoglobin A1c, lipid profile panel, glutathione peroxidase, superoxide dismutase, catalase, and antioxidant capacity/activity were determined;values are presented as mean ± standard deviation. Intra- and intergroup differences were tested by Wilcoxon signed rank and Mann-Whitney U test, respectively;p-value ≤ 0.05 was considered statistically significant. Results: The acetylsalicylic acid group showed a decrease in weight (85.6 ± 19.3 vs. 84.1 ± 19.0 kg p = 0.01), cholesterol (205.9 ± 16.6 vs. 186.0 ± 23.2 mg/dL p = 0.02), and glycated hemoglobin A1c (7.8% ± 0.9% vs. 7.0% ± 0.7% p = 0.02). The placebo group exhibited reduction in weight (76.1 ± 14.9 vs. 74.9 ± 15.0 kg p = 0.04), glycated hemoglobin A1c (6.9% ± 0.6% vs. 6.2% ± 0.4% p = 0.004), and total antioxidant capacity (4.1 ± 0.5 vs. 4.8 ± 0.3 mmol/L p = 0.002). Conclusion: The administration of acetylsalicylic acid did not modify the antioxidant enzyme system.

A method for adsorption involving banana peel (BP) was studied to remove the pollutant acetylsalicylic acid (ASA) in aqueous medium. The results show that bioadsorbent has satisfactory maximum adsorption capacity (2.29 mg/g) for removing this analgesic and anti-inflammatory drug in aqueous solution (pH 7.0) using the Langmuir mathematical model. The tested concentrations of this pollutant were higher than the levels commonly found in the aquatic environment. This and other results suggest the BP as an alternative to ASA removal in water contaminated with pharmaceuticals pollutants.

引用

Journal of Chinese Pharmaceutical Sciences 2005年第3期14卷 186-192页

作者：徐英库宝善耿兴超姚海燕张永鹤韩继生齐世荃北京大学医学部基础医学院药理学系北京100083 南宁枫叶药业有限公司广西南宁530012

Aim To study the effects of tetrodotoxin （TTX） combined with acetylsalicylic acid （ASA） on nociceptive stimulus in mice. Methods To assess the antinociceptive effects of TTX, ASA or TTX plus ASA, the acetic acid-induced abdominal constriction test and formalin pain test were used. Results TTX （0.5 - 4.0 μg· kg^-1 ） or ASA （25 - 200 mg· kg^-1 ） im produced a significant inhibition of acetic acid-induced abdominal constriction. The median inhibitory doses （ID508） were 2.1 μg· kg^-1 for TTX（ and 64 mg· kg^-1 for ASA. TTX and ASA also showed a dose-dependent inhibition of the second phase response in the formalin pain model, the ID508, being 2.3μg·kg^-1 and 74.2 mg· kg^-1, respectively. The ihteraction between TTX and ASA was synergistic, as evidenced by the fact that （1） when ASA alone compared with the combination of TTX （0.79 μg · kg^-1 or 0.39μg· kg^-1 ） and ASA, the ID508, of ASA reduced from 64.0 mg· kg^-1 to 5.8 mg· kg^-1 or 12.6 mg· kg^-1, and from 74.2 mg· kg^-1 to 7.4 mg· kg^-1 or 13.0 mg· kg^-1 on tile two models of nociceptive tests, respectively; and that （2） synergism in the analgesic effects was shown by isobiolographic analysis. Conclusion TTX, ASA and the combination of the two drags produce analgesic effects in acetic acid-induced abdominal constriction test and formalin-induced pain test. The interactions between TTX and ASA may be useful in developing novel analgesic agents.

Grafting of MIPs from PVDF Membranes via Reversible Addition-fragmentation Chain Transfer Polymerization for Selective Removal of p-Hydroxybenzoic acid

引用

Chemical Research in Chinese Universities 2018年第6期34卷 1051-1057页

作者： DONG Yanying YU Ping SUN Qilong LU Yang TAN Zhenjiang YU Xiaopeng School of Computer Science Key Laboratory of Numerical Simulation of Jilin Province School of Management Jilin Normal University Siping 136000 P. R. China

Effective molecularly imprinted membranes（MIMs） were developed as an efficient adsorbent for the selective removal ofp-hydroxybenzoic acid（p-HB） from acetylsalicylic acid（ASA, aspirin）. The MIMs were grafted successfully from poly（vinylidene fluoride） microfiltration membranes via reversible addition-fragmentation chain transfer（RAFT） polymerization. The graft copolymerization of acrylic acid（AA） in the presence of template p-hydroxybenzoic acid led to molecularly imprinted polymer（MIP） film coated membranes. The obtained MIMs were characterized by scanning electron microscopy（SEM）, Fourier transform infrared spectrophotometer（FTIR） and Raman spectra, and batch mode adsorption studies were carried ont to investigate the specific adsorption equilibrium, kinetics and selective recognition properties of different MIMs. The kinetic properties of the MIMs could be well described by the pseudo-second-order rate equation. Selective permeation experiments were performed to evaluate the permeation selectivity of the p-HB imprinted membranes. The observed performances of the MIMs are applicable to the further purification of aspirin.
