Os autores definem mastalgia cíclica pré-menstrual, (MCPM), repassam os principais mecanismos do ciclo celular da mama, e com base nestes conhecimentos propõem a sua classificação em três tipos, segundo a fisiologia do ciclo mamário: tipo 1 - caracterizado pela distensão localizada de ductos e adensamento do tecido conjuntivo em volta de pequenas dilatações. tipo II - caracterizado pelo edema intersticial, e tipo III - caracterizado pela combinação dos dois processos etiopatogênicos. OBJETIVO: Por meio de estudo prospectivo, aleatório, triplo cego e controlado, comparar a ação de placebo com associação de vitaminas A-D-E e doses baixas de ácido acetilsalicílico. MÉTODOS: Foram observadas 259 portadoras de MCPM, acompanhadas durante seis meses para estudo comparativo das drogas empregadas no alívio da dor. Destas, foram selecionadas 81 pacientes por critérios rigorosos, divididas em três grupos de 27, que receberam, respectivamente, aspirina, associação de vitaminas e placebo. A dor foi classificada em grau I (sem dor), grau II (dor moderada) e grau III (dor intensa). Os métodos estatísticos realizados mostraram que o número de pacientes em cada grupo era satisfatório. Foi empregado o teste de Tukey para comparação dos resultados e significância a 5%. RESULTADOS: As características clínicas, idade, peso, altura e IMC, antecedentes obstétricos e duração da amamentação foram semelhantes nos três grupos. Houve redução de intensidade da dor nos três grupos, principalmente naquele que recebeu placebo. CONCLUSÃO: O estudo realizado, segundo metodologia aceitável, porque foi prospectivo, controlado, triplo cego e aleatório, não mostrou diferenças significativas no tratamento da mastalgia cíclica pré-menstrual entre aspirina e associação de vitaminas, mas revelou superioridade do placebo.

Questions of psychological interference have been white of the researchers, that identify in the emotional states, a key precious and important in the fight to get a significant result in the esportivo context. The present study it raised questions of interest of sciences of the sport, objectifying to check the influences of the emotional states of players of handebol and its possible interferences in the esportivo income. We work with a qualitative research, leading given next to the athletes and commission technique of the team of handebol of Sorocaba; using questionnaires structuralized and halfstructuralized for the collection of data. All the gotten results had been represented graphically and analyzed front to the theoretical referencial of the area. These results in had shown them that inside of the searched universe, consequentemente exist some factors that intervene with the esportivo income of the majority of the athletes , affecting in a generalized manner the income of the team. In this way we have that it is not only enough to give attention to the physical training, technician and tacticians. It is necessary to give a special attention to the psychological factors of the athletes, so that in a competition they can relieve everything that that has condition to relieve. Finally, we more suggest deepened research inside of this area so that let us can better understand and take attitudes with regard to subjects as the Daily paymenstrual Tension and the question of the leadership, in the form of case studies. We also suggest an intervention of work of a psychologist of the sport acting next to team since the phase of definition of objectives until the ends of the championship.

This project aimed to relate the efficiency of control of ACCase inhibiting herbicides applied post-emergence in Cenchrus echinatus under different soil water contents. The experiments were conducted in a greenhouse, with the application of three different herbicides (fluazifop-p-butyl, haloxyfop-methyl and sethoxydim + oil Assist) and the experimental design for each herbicide was completely randomized design with four replications, consisting a 3 x 4 factorial, with the combination of water management strategies (-0.03, -0.07 and -1.5 MPa) and four doses of these products (100, 50, 25 and 0% of the recommended dose). Herbicide application was made at vegetative stage of 2-3 tillers. The water management strategies were initiated in the development stage of two leaves, replacing the water until the soil reaches the potential of -0.01 MPa, when it came to severe pre-determined for each water management. The physiological parameters evaluated were: photosynthetic rate, stomatal conductance, transpiration, leaf temperature and plant dry matter. The visual assessments of phytotoxicity were performed at 7, 14, 21 and 28 days after application. The efficiency of these herbicides was influenced by soil management and water lowest in plants grown in the minimal potential of water in the soil of -1.5 MPa. All the herbicides were unsatisfactory controls in applications late (2-3 tiller plants).

Currently, the use of herbicides is essential in a practical and common in agricultural areas, but efficiency of these herbicides can be compromised when applied on plants that thrive in water deficit conditions, due to low uptake and translocation of the product. Therefore, the aim of this study was to compare the efficiency of control ACCase inhibiting herbicides applied post-emergence in plants of Eleusine indica under different soil water contents. The experiment was conducted in a greenhouse and the experimental design was completely randomized design with four replications, consisting of a 9x4 factorial, with the combination of three soil water potentials (-0.03, -0.07 and -1.5 MPa) three herbicides (fluazifop-p -butyl, haloxyfop-methyl and sethoxydim + oil) and four doses (0, 25, 50, and 100 % of the recommended dose). Herbicide application was made in plants in vegetative stage 2-3 tillers. The soil water potential was initiated in the development stage of two leaves, and the water was supplemented until the soil reaches the potential of -0.01 MPa, when it came to minimum pre-determined for each water management. The physiological parameters evaluated were: photosynthetic rate, stomatal conductance, transpiration leaf temperature and plant dry mass. The visual assessments of phytotoxicity were performed at 7 and 14 days after application. The herbicides behaved in different ways according to the used water management. In severe water stress conditions (soil moisture at 8%) only fluazifop-p-butyl herbicide achieved satisfactory control (> 90%) in E. indica plants.
