Paperback. Condizione: New. Print on Demand. This book analyzes the chemical problems of medicine and the reasons that have delayed their resolution. It explores the impact of unproven hypotheses and the presence of false facts, which have hindered progress in the field. The author argues that these problems have led to a lack of trust in chemical methods among medical practitioners, and he provides several examples to illustrate the extent of the problem. The author also discusses the challenges involved in establishing professorships in physiological chemistry and the difficulties that researchers face when attempting to secure funding for their work. Ultimately, the book highlights the significance of addressing these issues in order to advance the understanding and application of chemistry in the field of medicine. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Giessen, J.Richer'sche Buchhandlung, 1851, 8°, 3 Bl., 43 pp., 23 Holzschnitte, Halbleinenband der Zeit, mit beigebundener original Broschur. His rare medical thesis! J.L.W. Thudichum (1829-1901) - "The interests, avocations, publications, and research career of Johann Ludwig Wilhelm Thudichum were unusually rich and diverse, although his primary devotion-lasting to the end of his life in 1901-was the relatively unknown field of brain chemistry. He performed chemical analyses on over a thousand brains, both human and animal, and has been called the first English biochemist and the world's first pathological chemist. His career was characterized by voluminous work, although during life he failed to achieve the acclaim he deserved. His greatest work, A Treatise on the Chemical Constitution of the Brain, raised great criticism and garnered outright rejection by the most prominent scientists of the era, those with the most to lose if surpassed by one of lesser prominence and reputation. Thudichum was born in Büdingen, Germany, on August 27, 1829. In 1847, at the age of 18, he began medical school at the University of Giessen, where he worked after hours in the laboratory of Julius Liebig, the foremost chemist of his day. It was in Liebig's laboratory where Thudichum developed an interest in biological chemistry. Over his 50-year career as lecturer, practitioner, chemist, author, laboratory director, public health official, and researcher, his creative and pragmatic nature spawned both innovation and a deeper understanding of the human body. He is honored by ear, nose, and throat physicians for his invention of the nasal speculum; by gastrointestinal physicians for his classic early work on gallstones; and by urologists for A Treatise on the Pathology of Urine, Including a Complete Guide to Its Analysis . Outside the field of medicine he gained recognition as the author of seminal works on the history and science of wines and cookery. Neuroscience honors Thudichum for his visionary understanding of the brain as an organ that could be understood chemically, i.e., that the pathway to treating brain disease could become available once a chemical profile of the brain was achieved. Over years of meticulous toil, usually performed in his home laboratory, he isolated, characterized, and named numerous brain-derived compounds such as cephalin, sphingomyelin, galactose, lactic acid, and sphingosine. He criticized and disproved the concept that brain matter was composed of a single giant molecule, protagon, that determined the various specialized properties of the brain. Like his contemporaries Darwin and Mendel, many of his ideas were beyond the conventional thinking of his day. His attempts to understand the chemistry of the brain were often hotly debated and mocked. At times, even his personal character was attacked, as well as his honesty and motives. In the scientific press, he was called a "liar" and accused of "patent falsification." Time, however, has awarded him victory. Ultimate vindication came in the 1930s when samples of his carefully extracted brain isolates were rediscovered, re-analyzed via modern techniques, and found to be both chemically pure and of the molecular composition that Thudichum had asserted. An innovative and inscrutable scientist, Thudichum lived and worked by the maxims he preached: "Scientific work, unless accurately done, had better not be done at all," and "Preconceived opinion is the pretended assumption by man of godly attributes which he does not possess." Thudichum promised in his treatise that students of the brain would find it "the most diversified chemical laboratory of the animal economy," suggesting that the most elaborate chemical structures and combinations, processes, and conditions would render previously unfathomable "mental phenomena and their aberrations under the influence of disease. much less difficult" (2). As with Galileo's theory of heliocentrism, no .

Cbl. med. Wiss., 7/ 1. - Berlin, August Hirschwald, 2. Januar 1880, 8°, 16 pp., Rückenbroschur. First printing of the Preliminary Notice and the naming "Lutein". "Verschiedene Theile von Thieren und Pflanzen enthalten eine gelbe crystallisirbare Substanz, welche bisher nicht unterschieden worden ist, und der ich nach ihrer hervorstechendsten Eigenschaft den Namen Lutein beilege." Thudichum "At about the same time that the Palermo workers were isolating the luteal pigment, Johann Ludwig Wilhelm Thudichum was conducting research on the "yellow organic substances contained in animals and plants." "One of the techniques Thudichum (1829-1901) used in his work was spectroscopic analysis, which he had learned in Heidelberg from Bunsen in 1855 during an interlude in his medical studies. In 1868 he published a classic paper in the Proceedings of the Royal Society (Results of Researches on Luteine and the Spectra of Yellow Organic Substances Contained in Animals and Plants, Proc. R. Soc., London, 1868-69, 17, pp.252-256), in which he provided spectroscopic details for a multitude of colored substances, among them Wackenroder's carotene. Although Thudichum was aware of Holm's paper, but apparently not of the work of the Palermo chemists, the spectrum for carotene proved to be virtually identical to that of Piccolo and Lieben's luteal pigment. Thudichum assigned the name "luteine" to this yellow crystallizable substance. He pointed out that: [I]n the vegetable world it is observed in seeds, such as maize; in the husks and pulps of fruits, such as annatto; in roots, such as carrots; in leaves, such as those of the coleus; and in the stamina and petals of a great variety of flowers. He examined 42 different plants in this study. Thudichum's luteine, insoluble in water, was easily soluble in alcohol, ether, and chloroform, forming yellow solutions. The chloroform solution when concentrated had an orange-red color. Thudichum is widely acknowledged as the first to define these yellow organic pigments as belonging to a new class of organic compounds." Theodore L.
