The Brain

Metallic cobalt acts as an epileptogenic agent when placed on the brain surface of some experimental animals. The mechanism by which this substance produces abnormal neuronal discharge is unknown. One potentially useful approach to this problem is to study the cellular and extracellular distribution of elemental cobalt in the meninges and adjacent cerebral cortex. Since it is possible to demonstrate the morphological localization and distribution of heavy metals, such as cobalt, by correlative x-ray analysis and electron microscopy (i.e., by AEM), we are using AEM to locate and identify elemental cobalt in phagocytic meningeal cells of young 80-day postnatal opossums following a subdural injection of cobalt particles.

Cardiopulmonary System

In recent years, non-human primates have become indispensable as experimental animals in many fields of biomedical research. Pharmaceutical and related industries alone use about 2000,000 primates a year. Respiratory mite infestations in lungs of old world monkeys are of particular concern because the resulting tissue damage can directly effect experimental results, especially in those studies involving the cardiopulmonary system. There has been increasing documentation of primate parasitology in the past twenty years.

The renal radiopharmaceutical preparations 99mTc-DMS and 99mTc-GH were examined chemically, biologically and clinically. Both preparations are of high radiochemical purity. The biodistribution of both preparations was examined in experimental animals at different time intervals, from 15 min to 4 hr; the percentage of incorporation of 99mTc-DMS into kidneys is much higher (29.4% to 52.0%) than that of 99mTc-GH (12.80% to 22.20%). Both preparations accumulate to a greater extent in the renal cortex than in the medulla.The most suitable time for renal scintigraphy for "mTc-DMS is 90-150 min while for 99mTc-GH it is 60-90 min. It is concluded that 99mTc-DMS is more suitable for static scintigrams on the scanner and 99mTc-GH for dynamic studies with the gamma camera.

Objetivo: Elaborar películas comestibles con la pectina extraída de la cáscara de piña, (Ananas comosus L.) y evaluar características de color, resistencia a la perforación y degradabilidad. Diseño/metodología/aproximación: Las películas comestibles se elaboraron utilizando el método de vaciado en placa (7ml y 10ml). Resultados: Las películas de pectina de cáscara de piña tuvieron valores de luminosidad y resistencia a la perforación menores (entre 42.18 ±0.47 y 31.07 ±0.66; entre 8.87 ±0.82 N y 3.61 ±0.4 N) que las del control (cítricos) (entre 86.0 ±0.26 y 85.46 ±0.99; entre 26.01 ±2.9 N y 18.82 ±1.9 N) pero su degradabilidad (% pérdida de peso) al primer día fue significativamente mayor (P<0.05); al final (7 d) ambos tipos de películas mostraron una degradabilidad similar (99%). Limitaciones del estudio/implicaciones: Se deben mejorar las propiedades físicas y mecánicas de las películas comestibles hechas con pectina extraída de la cáscara de piña. Hallazgos/conclusiones: Este trabajo demostró que las películas a partir de pectina de cáscara de piña son altamente biodegradables y no se descarta su uso y aplicación en alimentos; sin embargo, se requieren más estudios para la optimización de sus características físicas y mecánicas.
