Abstract: objective: to quantify the percentage of contractility of different myocardial segments in patients with chagas' disease by measuring myocardial strain and to assess the differences in the radial and longitudinal ventricular contractile function in the undetermined and dilated forms of chronic chagasic cardiomyopathy as compared with those in a group of healthy individuals. methods: the study comprised 39 individuals [20 (51.3%) of the male sex] divided into the following 4 groups: 1) nl: 17 (43.6%) healthy individuals; 2) und: 7 (17.9%) patients with the undetermined form of chagas' disease; 3) c1: 7 (17.9%) patients with the chronic form of chagas' disease with ejection fraction < 50%; and 4) c2: 8 (20.5%) patients with the chronic form of chagas' disease with ejection fraction > 50%. after performing baseline echocardiography, doppler tissue images were recorded to measure myocardial strain in different segments on longitudinal and transversal parasternal, and apical 2- and 4-chamber views. results and conclusion: the percentage of contractility in the different myocardial segments, both the radial and longitudinal components, is greater in healthy individuals than in patients with the chronic form of chagas' disease, and in those with the undetermined form of the disease as compared with that of chronic chagasic patients with ef < 50%. left ventricular radial contractility is greater than left ventricular longitudinal contractility in all groups (nl, und, and chronic). the data presented allow us to propose a progressive character of myocardial impairment in patients with chagas' disease.

Abstract: The interaction genotypes by environments is of fundamental importance in phenotypic manifestation. In order to verify the phenotypic stability of guava genotypes and to identify groups of accessions with alternative potentials for genetic improvement and for commercial exploitation, 63 accessions from the germoplasm bank of Instituto Agron mico (IAC, Campinas, SP) were evaluated. The evaluation period included six harvests, from 1987 until 1992. The methodology of simple linear regression was used to study phenotypic stability over time. The evaluated traits were fruit weight, crop duration and precocity. The most outstanding accessions were Campos and Creme Arredondada, which showed desirable averages and phenotypic stability for the three traits, besides stable accesses for two traits simultaneously and stable accesses for isolated traits. KEY-WORDS: GE interaction; adaptability; improvement; Mirtaceae; guava. A intera o de genótipos com ambientes é de fundamental importancia na manifesta o fenotípica. A fim de verificar a estabilidade fenotípica de genótipos de goiabeira e identificar grupos de acessos com potenciais alternativos para o melhoramento genético e/ou para a explora o comercial, foram avaliados 63 acessos do banco de germoplasma do Instituto Agron mico (IAC, Campinas, SP). O período de avalia o compreendeu seis safras, de 1987 a 1992. A metodologia de regress o linear simples foi utilizada para estudo de estabilidade fenotípica no tempo. Os caracteres avaliados foram peso de fruto, dura o de colheita e precocidade. Destacaram-se os acessos Campos e Creme Arredondada como de valores médios e estabilidade desejáveis para os três caracteres, além de acessos estáveis para dois caracteres simultaneamente e acessos estáveis para caracteres isolados.

Abstract: purpose: to study the hormonal production of the thyroid transplanted into the mesenteric fatty tissue. methods: forty-two wistar rats were used, 30 in the experimental group and 12 as controls, to test survival after 100 days of transplantation. half of the thyroid was removed and implanted into the mesenteric tissue. ten days later the half of the gland left in situ was removed. levels of thyroid hormones were measured at several different periods after transplantation, in serum from peripheral blood. removed tissue was submitted to histological, morphometric and ultrastructural analysis. results: morphologic studies were within normal limits. . the t3 and t4 hormones maintained their normal levels. tsh levels showed marked elevation, which subsided around the 75 day of transplantation, but remained elevated during the entire experimental period. levels of gamma-globulin remained within normal limits. conclusion: levels of t3 and t4 reflected the preservation of good thyroid function during mesenteric transplantation. the increased tsh levels revealed pituitary stimulation to a reduced amount of thyroid tissue. the autologous implantation of thyroid tissue is thus feasible and safe.

Abstract: this paper presents a social and environmental behaviour assessment of northeast brazil textile industry using the strategic assessment framework, named the triple-scp model. this model is an expansion of the structure-conduct-performance paradigm adding the assumption that the triple performance (economic, environmental and social) of a company is the result of its competitive practices or conduct standards, depending on the industrial structure in which it operates. the data were collected from textile companies located in ceará, paraíba, pernambuco and rio grande do norte states through in-depth personal interviews. the study categorized companies by size and identified social and environmental strategic conduct profiles. the conduct of the companies was rated as strong, medium or weak. the results show that most of firms adopt weak conduct on both social and environmental matters. overall companies are more concerned about environmental issues than social ones. in general, larger firms and those which have international markets tend to have a stronger environmental and social conduct.

Abstract: objective: we compared the shouldice (s) technique, a repair in four layers of continuous suture and the falci-lichtenstein (fl) technique that uses polypropylene prothesis. method: one hundred and eighteen male patients underwent surgery, on a total of 124 hernias. fifty-eight of them underwent inguinal hernia surgery by the fl technique, and the other 60 patients by the s technique. in each group 62 inguinais hernias with 85% of the patients were followed for four years. the average age was 52 years old. fifty-three type 3 a hernias, 57 type 3b and 10 type 4 hernias were operated, according to the nyhus classification. concerning the side, there was a predominance on the right with 65 ruptures (52.4%). the anesthesia was spinal in (89.8%) of the patients. results: the bruise and the seroma were the most common postoperative complications, occuring more frequently with the fl technique. in this one there was a recurrence (0,8%), because the bandage and the inguinal ligament broke up. in another patient, a femoral rupture turned up. the patients operated through the s technique complained more about pain on the immediate postoperative period and returned to work later. the observation time wasn't the ideal, because the largest index of recurrence can be in the non controlled patients, as it's known that 40% of the recurrence occur 5 years after the primary operation and 20% 25 years after. conclusions: both repairs presented low rates of recurrence. the shouldice technique is more complex, as it allows a safe exploration of the femoral channel, requires a more solid anatomical knowledge of the region and a better experience with the surgery of the inguinal hernia and it's a low cost procedure. the falci-lichtenstein repair is effective,rapid, causes fewer pain, fast recovery and allows less experienced inguinal hernia surgeons to accomplish it successfully.

Abstract: prediction of variety composite means was shown to be feasible without diallel crossing the parental varieties. thus, the predicted mean for a quantitative trait of a composite is given by: yk = a1 svj + a2stj + a3 - a4, with coefficients a1 = (n - 2k)/k2(n - 2); a2 = 2n(k - 1)/k2(n - 2); a3 = n(k - 1)/k(n - 1)(n - 2); and a4 = n2(k - 1)/k(n - 1)(n - 2); summation is for j = 1 to k, where k is the size of the composite (number of parental varieties of a particular composite) and n is the total number of parent varieties. vj is the mean of varieties and tj is the mean of topcrosses (pool of varieties as tester), and and are the respective average values in the whole set. yield data from a 7 x 7 variety diallel cross were used for the variety means and for the "simulated" topcross means to illustrate the proposed procedure. the proposed prediction procedure was as effective as the prediction based on yk = - ( -)/k, where and refer to the mean of hybrids (f1) and parental varieties, respectively, in a variety diallel cross. it was also shown in the analysis of variance that the total sum of squares due to treatments (varieties and topcrosses) can be orthogonally partitioned following the reduced model yjj? = m + ?(vj + vj?) + + hj+ hj?, thus making possible an f test for varieties, average heterosis and variety heterosis. least square estimates of these effects are also given
