Women's beliefs about the appetite and weight control properties of cigarette smoking, dietary restraint and disinhibition, and smoking status were examined. As hypothesized, dietary restraint and disinhibition predicted appetite and weight control expectancies and smoking rate, such that women higher in dietary restraint and disinhibition reported stronger beliefs in the appetite and weight control properties of cigarettes and were more likely to be smoking than those lower in dietary restraint and disinhibition. Consistent with previous research, smoking expectancies for appetite and weight control predicted smoking status and smoking rate. Smoking expectancies for appetite and weight control were found to mediate the relationship between dietary restraint and smoking, and between disinhibition and smoking. This relationship between smoking and dietary constructs should be considered in smoking cessation and dietary interventions with young women.  相似文献

Binary mixtures of dipyrone and pitophenone hydrochloride are assayed by zero-crossing second- and third-derivative spectrophotometry and by ratio-spectra first- and second-derivative spectrophotometry. In the first method, calibration plots are linear at 266.5 and 302.5 nm (dipyrone, second derivative), and 257 and 286 nm (pitophenone second derivative) and 242 and 278.3 nm (dipyrone third derivative), and 228.5 and 300 nm (pitophenone, third-derivative). By the second method, lines of regression are linear at 235 and 262 nm (dipyrone, first derivative), and 229.5 and 288.5 nm (pitophenone, first-derivative), and 249.7 and 268 nm (dipyrone, second derivative), and 280.5 and 300 nm (pitophenone, second-derivative). In all methods calibration curves follow the Beer's law up to 40 microg/ml of each drug. LOD and LOQ values were calculated. The developed derivative spectrophotometric methods were applied to laboratory mixtures and to vials for these drugs. The procedures are simple, rapid, and did not require any preliminary separation or treatment of the samples.  相似文献

Pharmacokinetic-pharmacodynamic (PK-PD) modeling is an integral part of the preclinical and clinical development of protein drugs. Bioanalytical data from appropriately selected and well-characterized PK and PD biomarker assays can be incorporated into mechanistic PK-PD models and allow a quantitative relationship between protein drug exposure, target modulation, and biochemical, physiological and pathophysiological effects to be established. The selection of PD biomarkers that assess target engagement and modulation in the extracellular milieu and downstream cellular effects can provide proof-of-mechanism and define the magnitude and duration of target modulation following drug administration. The PK-PD data can provide an important link between magnitude of target modulation and clinical efficacy and safety outcomes, and guide the selection of doses and dosing schedules for clinical trials. In this article, approaches to the selection and development of fit-for-purpose, PK and PD assays for protein drugs are reviewed, and the applications of the assay results in PK-PD models are discussed.  相似文献

Non-alcoholic fatty liver disease (NAFLD) is a major complication linked with the metabolic syndrome associated with dyslipidemia, inflammation, and oxidative stress. Impact of type 2 diabetes with hyperlipidemia in NAFLD has to be established, as well as the utility of commonly prescribed anti-diabetic and lipid-lowering agents in improving liver injury markers. Genetic type 2 diabetic Goto–Kakizaki rats were fed with a high-fat diet to test hepatic effects of type 2 diabetes with hyperlipidemia and the effect of atorvastatin and insulin, individually and in combination, in systemic and hepatic inflammatory and oxidative stress markers. High-fat diet aggravated fasting glycemia, systemic and liver lipids, and inflammatory and oxidative stress markers. Individual treatments improved glycemic and lipid profiles, but failed to improve inflammatory markers, whereas insulin was able to reduce liver oxidative stress parameters. Combination of insulin and atorvastatin further improved glycemic and lipid profiles and decreased circulating C-reactive protein levels and liver inflammatory and oxidative stress markers. Insulin and atorvastatin combination leads to better glycaemic and lipid profiles and to better protection against liver inflammation and oxidative stress, giving a superior level of liver protection in type 2 diabetic with hyperlipidemia.  相似文献

This article presents findings from an outpatient dual diagnosis demonstration project that investigated whether integrated treatment services for severely and persistently ill patients with co-occurring mental health and substance abuse disorders could result in improved outcomes and reduction of criminal justice and health care costs. Integrated treatment was defined as a simultaneous focus on both disorders through the provision of psychosocial rehabilitation, psychotherapeutic and psychopharmacologic treatment, and substance abuse recovery and relapse prevention by cross-trained staff. One hundred twenty six (126) patients with multiple DSM-IV Axis I and Axis II disorders were assessed on a variety of mental health, substance abuse, and quality of life measures at baseline and at six-month intervals up to three years post entry into treatment. Criminal justice and health care costs obtained from state and local databases were compared two years before and two years after initiation of treatment to determine cost differences. The study found statistically significant improvements in psychiatric symptoms, substance abuse, and quality of life outcomes. There were also decreases in criminal justice and acute and sub-acute mental health and alcohol and other drug (AOD) costs and increases in outpatient mental health and physical health care costs.  相似文献

Injection forms of potassium (K) and magnesium (Mg) aspartate (Asp) were compared in preventing cardiac disorders caused by electrolytic disturbances, primarily low K and Mg levels (e.g. caused by the treatment with cardiac glycosides and diuretic drugs). Widely used K- and Mg-Asp preparations (asparkam, panangin, pamaton) are synthesized from aspartic acid representing a racemic mixture of L- and D-stereoisomers. Differences in metabolism and utilization of D- and L-amino acids probably influence the pharmacological properties of K and Mg L- and D-aspartates. Moreover, the pharmacologically effective doses of Mg and K salts can induce toxicity, which depends on the nature of anions. The aim of this study was to compare of antiarrhythmic action of K and Mg L-, D-, and DL-Asp stereoisomers using calcium chloride (CaCl2) and aconitine induced arrhythmia models in rats and strophanthin-K induced arrhythmia model in guinea pigs. It was found that intravenously administered K- and Mg-L-Asp exhibited higher activity compared to K- and Mg-D- and DL-Asp on the strophanthin-K, CaCl2, and aconitine induced arrhythmia models. Indeed, K- and Mg-L-Asp more effectively decreased the incidence of arrhythmias, increased the time to onset of the first arrhythmia, decreased percentage loss of rats, and increased the survival life of animals after the first arrhythmia onset in rats with arrhythmias induced by strophanthin-K and CaCl2 as compared to K and Mg-D- and DL-Asp. At the same time K- and Mg-L-Asp was better than D- and DL-Asp with respect to acute toxicity (LD50), effective dose (ED50) and antiarrhythmic (therapeutic) ratio (LD50/ED50) in rats with aconitine-induced arrhythmia model.  相似文献

对药物的评价不仅决定于治疗剂量的大小,还取决于药物治疗剂量与中毒剂量差距的大小(即治疗指数及安全限).我们在寻找抗肿瘤新药的研究中,发现N-甲酸溶肉瘤素(以下简称N-甲)有明显的抗肿瘤作用.从化学结构看来,N-甲与溶肉瘤素非常相似,但临床观察表明,N-甲对溶肉瘤素不敏感的淋巴肉瘤、何杰金氏病却有明显疗效.因此,我们对N-甲及溶肉瘤素在三种动物肿瘤作用的效价进行了比较.本文即研究初步结果的简报.材料及方法药物系由我所药物化学系合成室供给.N-甲批号是6103,熔点为148-151℃,实验前将药物混悬于2%淀粉糊中.溶肉瘤素批号是S615,熔点为178-181℃,实验前将药物用70-80℃蒸馏水溶解,现用现配.  相似文献
