Estudio morfológico de la segmentación esplénica / Morphological study of the spleen segments

Se estudiaron 46 bazos humanos, donde se evidencia que: el tipo I de distribución extrabilial con dos ramas., (incluyendo arterias polares como ramas) 71.7% y del tipo II con tres ramas en el 28.2% de los órganos. La incidencia de polar superior en forma global, alcanzó el 19%, mientras la polar inferior alcanzó el 47.8% ya dentro de hilio esplénico, demostramos el tipo I en el 67.3% mientras el tipo II se demostró en el 32.6% de nuestro estudio. En la distribución segmentaria o parenquimatosa, nuestro estudio. En la distribución segmentaria o parenquimatosa, la presentación en cuatro segmentos fué la dominante con 54.3%, seguida por la de tres con 23.9% y finalmente la de cinco con 21.7%. Con el presente estudio se demuestran las observaciones sobre las características morfológicas de la circulación esplénica en nuestro medio, las cuales nos sirven de base fundamental para realizar la cirugía planificada y conservadora del bazo

Distribution of 5-hydroxytryptamine and histamine in tissues of WLH chicken.

5-Hydroxytryptamine and histamine were estimated in lungs, liver, spleen and adrenals of chicken. A substantial amount of both the amines was found in all the organs. The highest level of both the amines was found in adrenals followed by spleen, lungs and liver. The level of 5-hydroxytryptamine was, however, higher than histamine in all the tissues except adrenals.

Acetylcholine content of the brain and visceral organs of the teleostean fish; Heteropneustes fossilis and Clarias batrachus.

The acetylcholine content of various organs of two teleostean fish, Heteropneustes fossilis and Clarias batrachus has been estimated biologically on the eserinized frog rectus muscle. The acetylcholine content in the stomach of both the fish was 0.341 and 0.22 mug/g, respectively. Values were lower than those of other parts of the alimentary tract. The ilia contained the most acetylcholine, being 0.644 and 0.551 mug/g respectively, for the two fish. In the brain, heart, kidney and liver of both the fish, a considerable amount of acetylcholine was detected. Acetylcholine was not found in the spleen of Clarias batrachus, but it was present in the spleen of Heteropneustes fossilis.
