Resumen en español El estudio tuvo por objetivo investigar histométricamente los efectos tóxicos de la exposición al ión cadmio sobre la glándula submandibular en rata adulta. Ratas machos, de peso aproximado a 170 g, recibieron, en el bebedero, una solución de 300 mg de cloruro de Cd/l de agua, durante 6 meses. Otro grupo de animales, después del tratamiento, permaneció en recuperación durante un período adicional de 6 meses. El parénquima de las glándulas submandibulares mostr (mas) ó marcada diferencia entre los animales tratados y controles. Los acinos de las glándulas de las ratas intoxicadas con Cd, eran menores, de forma irregular y con células degeneradas. Los núcleos variaron de tamaño pero no de forma. Los ductos estriados, granulosos y excretores estaban desorganizados, mostrando núcleos menores. El cuadro histológico de la glándula submandibular de las ratas sometidas, a recuperación de la intoxicación, durante 6 meses fue semejante al de los controles. Este resultado fue confirmado mediante el estudio histométrico. Basados en la literatura, los autores afirman que la metalotioneína actúa como agente desintoxicante uniéndose al Cd y que la disminución de su síntesis aumenta la concentración de Cd libre, provocando daños al ADN e inhibiendo la síntesis proteica, como fue observado en el presente trabajo Resumen en inglés The present study has the objective to investigate histometrically the toxic effects of cadmium ion exposition on the submandibular gland of adult rats. White male rats, weighing around 170 g, received, in the drinking trough, a solution of 300 mg cadmium chloride/l of water, during 6 months. Another group of animals, after similar treatment, remained in recuperation during an additional period of 6 months. The parenchyma of the submandibular gland showed marked differenc (mas) es between intoxicated and control animals. The acini of the gland of the Cd-intoxicated group were smaller, with irregular shape and degenerating cells. The nuclei varied in size but not in shape. Striated, granulous and excretory ducts were disorganized showing smaller nuclei. The histologic picture of the gland in the 6 months recuperated rats was similar to that of the control. This result was confirmed by the histometrical study. Based in the literature, the authors conclude that the methallothionein can act as a detoxicant agent by joining to Cd, and its decreased synthesis rises the concentration of free Cd, that causes damages to DNA and inhibits the protein synthesis, as observed in the present study

Resumen en español Se estudiaron los daños primarios producidos por la radiación gamma en el ADN de cepas de Escherichia coli portadoras de la fusión génica sulA::lacZ y de mutaciones en diferentes genes de reparación del ADN. Además, se determinó su radiosensibilidad. Las cepas con mutaciones en los genes recN y uvrA fueron más sensibles que la tipo salvaje. Esto concuerda con estudios previos donde se demostró que los genes rec y uvr participaban en la reparación del daño en el (mas) ADN producido por los rayos gamma. En las cepas mutantes se encontraron diferencias significativas en los niveles de expresión del gen sulA en relación con el tipo salvaje. Se discute la utilidad de las cepas estudiadas como biosensores de genotoxicidad así como en estudios de radioprotección. Resumen en inglés The primary damages produced by the gamma radiation in the DNA of Escherichia coli strains carriers of the sulA::lacZ genic fusion and of mutations in different DNA repair genes were studied. Its radiosensititvity was also determined. The strains with mutations in the recN and uvrA genes were more sensitive than the wild type. This agrees with previous studies where it was proved that the rec and uvr genes take part in the repair of the DNA damage produced by the gamma ra (mas) ys. In the mutant strains, there were found significant differences at the level of expression of the sulA gene in relation to the wild type. The usefulness of the strains studied as genotoxicity biosensors and in radioprotection studies was discussed.

Resumen en español Existen evidencias que tanto los ácidos biliares como el Helicobacter pylori en la mucosa gástrica son capaces de desencadenar un proceso inflamatorio que según su intensidad y persistencia favorecen la aparición de fallas y mutaciones en la replicación celular que se expresan desde una metaplasia, displasia hasta un cáncer. Se realizó un estudio epidemiológico observacional, descriptivo, prospectivo de corte transversal en el Instituto de Gastroenterología, en p (mas) acientes con reflujo duodenogástrico y ácidos biliares totales elevados, con el objetivo de conocer la asociación entre la metaplasia intestinal y la presencia o no de Helicobacter pylori. Al concluir la investigación se observó que la metaplasia estuvo presente en 48,7 % de los 39 pacientes estudiados, que existió una asociación estadísticamente significativa (p Resumen en inglés The cytotoxic and cancerous action of bile acids on gastric mucosa is a very interesting subject within the gastroduodenal diseases due to they are able to alter the membrane, the cellular metabolism, to give rise to a inflammatory process, to increase the proliferation, the cell apoptosis and the DNA damage, that according to its intensity and persistence, favor the appearance of failures and mutations in cell replication. With the discovery and characterization of Helic (mas) obacter pylori it is considered that according to its intensity and the time of persistence in gastric mucosa provokes damages with failures and cellular mutations. In this sense, a prospective and descriptive study was conducted in the Institute of Gastroenterology in patients presenting with duodenogastric and high total bile acids to know the association between the intestinal metaplasia and the presence or not of Helicobacter pylori. Metaplasia was present in the 48.7 % of the 39 study patients, that there was a statistically significant association (p
