ABSTRACT
Resumen Una de las obras, probablemente menos conocidas, de Antoine van Leeuwenhoek (1632-1723) es su Arcana naturae detecta (Secretos detectados de la naturaleza) publicada en su primera edición en 1695. Esta obra es una recopilación de 38 cartas sobre temas científicos y está bellamente ilustrada. Una sección notable de ella es la observación y descripción por primera vez de levaduras de la fermentación y sus experimentos sobre la generación espontánea de microorganismos.
Abstract One of the works, probably less known, of Antoine van Leeuwenhoek (1632-1723) is his Arcana naturae detecta (Detected secrets of nature) published in its first edition in 1695. This work is a compilation of 38 letters on scientific issues and it is beautifully illustrated. A notable section of the work is the observation and description for the first time of fermentation yeasts and his experiments on the spontaneous generation of microorganisms.

Resumen Antoine van Leeuwenhoek (1632-1723) fue un comerciante de telas holandés y microscopista autodidacta, a quien se le considera el padre de la Microbiología. Sus sorprendentes lentes y agudas observaciones microscópicas durante casi cinco décadas posibilitaron por primera vez desentrañar los secretos del microcosmos. Este trabajo de investigación tiene como objetivo principal que el lector pueda acceder de manera directa a algunas de sus famosas cartas dirigidas a la Sociedad Real de Londres, anunciando el descubrimiento de sus celebérrimos animálculos.
Abstract Antoine van Leeuwenhoek (1632-1723) was a Dutch cloth merchant and self-taught microscopist who is considered the father of Microbiology. His marvellous lenses and keen microscopic observations over nearly five decades made it possible for the first time to unravel the secrets of the microcosm. The main objective of this work is that the reader can directly access some of his famous letters addressed to the Royal Society of London, announcing the discovery of his famous little animals.

From the theory of Girolamo Fracastoro in 1530, suggesting the participation of invisible seeds in the contagion of some diseases, to the universal genius Athanasius Kircher, who saw little worms in the blood of patients suffering from plague in 1659 and the final discovery of Anthony Van Leeuwenhoek in 1674, the existence of bacteria was surely in the mind of a few investigators. Kirchner, who seems to be the winner of this race, did not give any special meaning to his observations. Leeuwenhoek, instead, was deeply concerned about the importance of his discovery in the field of biology, but was unable to establish a link between these animalcula and human epidemic diseases.

Marcello Malpighi, (1628-1694), Italian physician, anatomist, botanist, histologist and biologist developed methods to study living things by using the newly invented microscope to make a number of important discoveries about living tissue and structures, and initiated the science of microscopic anatomy. For almost 40 years he used the microscope to describe major types of plant and animal structures and, in doing so, discovered major areas of research in botany, embryology, human anatomy and pathology for future generations of biologists. He provided anatomical basis for eventual understanding of human physiological exchanges. Marcello Malpighi was the founder of microanatomy. Many microscopic anatomical structures are named after him: the basal layer, renal corpuscles, as well as insect excretory organs.
Marcelo Malpighi, (1628-1694), médico italiano, anatomista, botánico, histólogo y biólogo, usando el microscopio, recientemente inventado en esa época, desarrolló métodos para estudiar organismos vivos, con lo cual contribuyo al inicio del desarrollo de la ciencia de la anatomía microscópica. Por casi 40 años Malpighi utilizó el microscopio para describir los tipos principales de estructuras de algunas plantas y animales, facilitando el inicio de campos de investigación importantes en botánica, embriología, anatomía humana y patología. Marcelo Malpighi fue fundador de la anatomía microscópica. Muchas estructuras anatómicas microscópicas se nombran en su honor, como; la capa de Malpighi, los corpúsculos renales, así como los túbulos renales.

The history of science should be incorporated into science teaching as a means of improving learning and also to increase the students' understanding about the nature of science. In biology education, the history of microscopy deserves a special place. The discovery of this instrument not only opened a new and fantastic microworld but also led to the development of one unifying principle of biological sciences (i.e., cell theory). The microscopes of Leeuwenhoek and Hooke opened windows into the microworld of living organisms. In the present work, the knowledge of these themes was analyzed in a group of students beginning an undergraduate biology course. Our data suggest that the history of microscopy is poorly treated at the secondary school level. We propose a didactic activity using a replica of Leeuwenhoek's microscope made with Plexiglas and a lens obtained from a key chain laser pointer or from a broken CD drive. The proposed activity motivated students to learn about microscopy and helped them to appreciate scientific knowledge from a historical perspective.

Johannes Vermeer and Anthon van Leeuwenhoek are among the greatest geniuses in Art and Science respectively. During the seventeenth century, they achieved innovative advances. Vermeer, in painting, created a new intimate view of people specially women, developing the treatment of light and details. Leeuwenhoek, friend of Vermeer, influenced him in the use of the obscure camera in his works. In spite of having no formal academic education, he made extremely relevant discoveries with the use of microscope. He showed for first time human spermatozoids, red blood cells, brain, nerve and muscle structures and described many living animals. These two brilliant contemporary Dutch men made a great contribution to our civilization.

El conocimiento sobre el cuerpo humano y la curiosidad que desde siempre ha despertado en el propio Hombre para tratar de comprender su composición, funcionamiento, reacciones, actitudes, e intentar responder a las múltiples interrogantes que por el solo acto de ser organismos vivientes y racionales nos plantea, ha sido objeto del desarrollo y evolución de la Anatomía Humana. A los estudios realizados sobre esta disciplina del saber se han incorporado en el transcurso del tiempo los efectuados por la Embriología, Histología, Citología, Fisiología, Patología y la Genética, lo cual ha ido configurando un contexto en el cual el sujeto -desde el punto de vista estructural y funcional- ha sido parcialmente o casi totalmente develado. En la presente revisión se analizan los distintos métodos empleados en el desarrollo y evolución de la Tecnología Médica en el área de la morfofisiohistocitopatología en el campo de la investigación y su integración mediante aportes concretos en el ámbito de la Anatomía Microscópica y su proyección y aplicación al diagnóstico clínico.
