The response of rat quadriceps muscle fibers to chronic streptozotocin (STZ) diabetes was studied. Transverse sections of rectus femoris muscle from diabetic and weight-matched control rats were assayed for myofibrilar adenosine triphosphatase (ATPase) and nicotinamide adenine dinucleotide-tetrazolium reductase (NADH-TR). A quantitative analysis was carried out by an automatic interactive analysis system focused on the fiber type size and distribution. STZ-induced diabetes caused important effects in this muscle, with changes in the distribution of oxidative enzyme reactions, type I fiber hypertrophy, and type II fiber atrophy, which was greater in type IIB than in type IIA. It is concluded that hypoinsulinism produces morphological alterations in proximal skeletal muscle fibers that are similar to those of neurogenic myopathy. Thus the pathological changes in these mammalian muscle fibers could explain the clinical syndrome seen in diabetic patients called "diabetic symmetrical proximal motor neuropathy," perhaps the least understood of the major neuropathic complications of diabetes.

Fundamento. Los lesionados medulares y sus cuidadores tienen acceso en internet a folletos que pueden usar como complemento educativo frente a formas tradicionales de educación. El objetivo del estudio es valorar la legibilidad de los documentos informativos en español, obtenidos de internet y dirigidos a lesionados medulares. Material y métodos. Se realizó una búsqueda en el buscador Google con las siguientes palabras clave: recomendación, consejo, guía, manual, autocuidado, educación e información, añadiendo lesión medular, paraplejia o tetraplejia con cada uno de los términos. Analizamos los primeras 50 resultados de cada bús-queda. La legibilidad de los folletos se estudió con los índices de Flesch-Szigriszt y el grado INFLESZ, ambos disponibles en el programa INFLESZ. También se indicó el año de publicación, el país y el número de autores de los documentos obtenidos. resultados. Se obtuvieron 16 documentos, elaborados entre 2001 y 2011. La legibilidad osciló entre 43,34 (algo difícil) y 62 (normal), con un valor medio de 51,56 (algo difícil). Solo 4 folletos (25%) presentaron un índice de Flesch-Szigriszt ≥ 55 (normal). No hay diferencias en la legibilidad según el año, los autores o el país de edición. conclusiones. La legibilidad del 75% de los documentos estudiados es "algo difícil" según la escala INFLESZ. Estos resultados coinciden con estudios previos, tanto en español como en inglés. Si conseguimos mejorar la legibilidad de este tipo de documentos, su objetivo educativo será más fácil de alcanzar. Palabras clave. Lesión medular. Legibilidad. Folletos educativos. Internet. abstract background. Patients with spinal cord injuries and their carers have access to leaflets on Internet that they can use as educational material to complement traditional forms of education. The aim of this study is to evaluate the readability of informative documents in Spanish, obtained from Internet and aimed at patients with spinal cord injuries. Methods. A search was made with the Google search engine using the following key words: recommendation, advice, guide, manual, self-care, education and information, adding spinal cord injury, paraplegia and tetraplegia to each of the terms. We analyzed the first 50 results of each search. The readability of the leaflets was studied with the Flesch-Szigriszt index and the INFLESZ scale, both available on the INFLESZ program. Also indicated were year of publication, country and number of authors of the documents obtained. results. We obtained 16 documents, developed between 2001 and 2011. Readability oscillated between 43.34 (somewhat difficult) and 62 (normal), with an average value of 51.56 (somewhat difficult). Only 4 pamphlets (25%) showed a Flesch-Szigriszt index of ≥ 55 (normal). There was no difference in readability by year, authors or country of publication. conclusions. The readability of 75% of the documents studied was "somewhat difficult" according to the IN-FLESZ scale. These results coincide with previous studies, in both Spanish and English. If the readability of thi...

The websites analysed present a medium quality. Mainly, they should improve the reliability of their contents and their readability, including more quality labels. For SCI information in Spanish to be understandable and to provide valuable content, websites analysed in our study need to improve the quality parameters.
