Avaliação dos efeitos promovidos pela sibutramina, associadas ou não à nicotina, nos tecidos reprodutivos de ratas albinas

Sibutramine is a drug recommended clinically for the treatment of obesity, but there are women that use the drug for maintenance of body weight. Many time this use occur associate to habit of tabagism, being the nicotine the main toxic compound in the cigarette. The goal of study was to evaluate the side effects promoted by sibutramine, associated or not to nicotine, in the reproductive tissue of adult female rats. Wistar animals (n = 30), were distributed in the groups: a) Control A (0.3 mL of distilled water; oral); b) Sibutramine (15 mg/kg of body weight; oral); c) Control B (0.3 mL of saline solution; intraperitoneal); d) Nicotine (4.0 mg/kg of body weight; intraperitoneal); e) sibutramine + nicotine. The treatments were conducted during 30 consecutive days (single dose, daily). Sibutramine, associated or not to nicotine, affected the folliculogenesis and luteogenesis. There were significant alterations (p<0.05) in the thickness of uterine layers, considerate each treatment. In conclusion, the administration isolated of sibutramine or nicotine promoted deleterious effects in the reproductive tissues of female rats and these effects were potential in the group that received both drugs.

Avaliação da atenção concentrada e memória em tabagistas com baixa carga tabágica

Introduction: Smoking is considered by World Health Organisation (WHO) a disease, since nicotine is addictive and cause physical, emotional and behavioral disorders in people who smoke. The objective of this study was to evaluate the concentrated attention and memory in smokers and nonsmokers, and the influence of one cigarette in this variables. Material and Methods: We selected two groups of subjects between 18 and 25 years, with no history of acute or chronic respiratory disease. Group 1 (G1) consist of 40 nonsmoking individuals and group 2 (G2) 40 smokers (who smoked less than 20 cigarettes per day, for up to 10 years). The subjects were tested for concentrated attention and memory test (AC Test), nonsmokers performed the test once, smokers performed the test twice, before smoking and after five minutes after smoking one cigarette. Smokers stayed without cigarret for one our before the first test. Results: Comparing the tests nonsmokers versus smokers first test, there was no significant difference (p> 0.05), however, the analysis of the two trials of smokers, showed improvement in concentrated attention and memory after smoke (p <0.0001). Conclusions: There was no difference in Concentrated Attention and Memory among nonsmokers and smokers in abstinence, however smokers showed significant improvement in AC Test after smoking.

Ocorrência de tabagismo e dependência nicotínica em universitários

In Brazil, smoking incidence varies between 9.5% and 21.2% and it is more common among men. In college students incidence can reach 14% depending on the region, which is quite disturbing. Joining college is a crucial period for the commencement or maintenance of smoking. The Knowledge among college students about tobacco use is critical to devise strategies for intervention in this population. The objectives were to establish the occurrence of smoking and risk factors, nicotine dependence in college students and college goers. We interviewed students, teachers and administrative personnel from the Philosophy and Science School at UNESP at Marilia, from both sexes, regardless their age, which visited the First Week Against Tobacco event. The sociodemographic data, smoking status, time as a smoker, cigarettes smoked, date when they started smoking, history of smoking in the family, friends or associates were questioned. We also assessed the degree of motivation to quit smoking and the degree of nicotine dependence. Data were presented using descriptive statistics. Comparisons between categorical variables were made using the chi-square test (p <0.05). A total of 432 people, 180 men and 252 women, average aged 22.6 ± 6.9 years were researched. From the volunteers studied, 267 (61.8) had tried cigarettes and 171 of them (64%) reported that they were offered by friends. As a whole, 79 (18.3%) of these people were smokers, 52 (65.8%) reported intending to quit smoking and in 37 of them (46.8%), the degree of nicotine dependence was very low. Of all the smokers, 63 had smokers in the family and all of them had friends who smoked. 28.9% of all men were smokers and 10.7%of all women. The occurrence of smoking was 18.3% and the risk factor associated to smoking habit is related to friendship and family, and very low nicotine dependence.

Síntese de tetra-hidropiridinas por meio de reações multicomponentes

Multicomponent Reactions are defined as reactions between three or more reagents in a single reaction step in the same reaction vial, forming a product that includes the majority of atoms and structural characteristics of the reagents. Thus these reactions save time and energy. One of the ways to improve the yield and reaction time of a multicomponent reaction is to use different catalysts, an example of catalyst that shows great potential and has been studied in recent years is the molecular iodine is known to be a Lewis acid with high catalytic power. The functionalized piperidines, also known as tetrahydropyridines, are alkaloids that have pharmacological potential, this is due to the piperidine ring present in many natural product structures with muscarinic activity, nicotine, analgesic, antipsychotic, anti-proliferative, among others. In this paper we describe studies about on the application of molecular iodine (I2) in the multicomponent reaction between aniline derivatives, benzaldehyde and β-ketoester (methyl acetoacetate) for the synthesis of functionalized piperidines and the synthesis of a corresponding piperidone by acid hydrolysis. Data analysis allowed us to demonstrate the efficacy of molecular iodine in the synthesis of functionalized piperidines, obtaining results with yields 44-87% and short reaction time of 8 to 24 hours, and the efficacy of acid hydrolysis of enamine in the structure of the tetrahydropyridine derivative in a yield of 81%
