Patentirt im Deutschen Reiche vom 17. November 1897 ab.Patented in the German Empire on November 17, 1897.

In der Schilddrüse findet sich, wie durch eingehende Untersuchungen nachgewiesen ist, ein Eiweifskörper, welcher zum Theil mit Jod substituirt ist. Dieser Eiweifskörper erhöht, ■per os oder subcutan eingegeben, die Eiweifs- und Fettumsetzungen im Körper des Menschen oder der Thiere. Das Jodothyrin (Thyrojodin) ist nur ein Spaltungsproduct der Eiweifssubstanz der Schilddrüsen und lä'fst sich durch das Fehlen der Biuretreaction von dem ursprünglichen Präparat unterscheiden; auch beweist der hohe Jodgehalt des Jodothyrins gegenüber demjenigen des Ausgangsmateriales, da fs bei seiner Darstellung eine weitgehende Spaltung eingetreten ist.In the thyroid gland, as has been shown by detailed investigations, there is a protein body, which is partly substituted with iodine. This protein body, when introduced per os or subcutaneously , increases the protein and fat conversions in the body of man or animals. The iodothyrin (thyroiodine) is only a product of splitting the protein substance of the thyroid gland and can be distinguished from the original preparation by the absence of the biuret reaction; The high iodine content of iodothyrin, compared with that of the starting material, also shows that extensive splitting occurred when it was prepared.

Extrahirt man die Schilddrüsen mit Hülfe einer schwachen Formaldehydlösung (etwa ι : 2000), so gewinnt man nicht nur die jodhaltige und wirksame Substanz in sterilem Zustande, sondern der Schilddrüsensaft verliert dabei auch seine Gerinnungsfähigkeit. Man erkennt dies ohne Schwierigkeit beim Aufkochen des Schilddrüsensaftes mit Salzlösung.If the thyroid glands are extracted with the aid of a weak formaldehyde solution (approx ι: 2000), not only is the iodine-containing and active substance obtained in a sterile state, but the thyroid juice also loses its ability to clot. You can see this without difficulty when boiling of thyroid juice with saline solution.

Giebt man keinen Formaldehyd hinzu, so tritt Gerinnung ein; anderenfalls bleibt die Lösung klar.If no formaldehyde is added, coagulation occurs; otherwise the Solution clear.

Dasselbe Verhalten wurde bereits für Eier- und Blutalbumin nachgewiesen, vermuthlich handelt es sich dabei um das Auftreten einer Methylenverbindung.The same behavior has already been demonstrated for egg and blood albumin, presumably it is the appearance of a methylene compound.

Bei dem Schilddrüsenextract tritt offenbar eine analoge Verbindung ein, bei deren Bildung aber selbst ein Ueberschui's von Formaldehyd eine Entgiftung des toxischen Principes der Thyreoidea nicht hervorruft.In the thyroid extract there is evidently an analogous connection when it is formed but even an excess of formaldehyde detoxifies the toxic principle the thyroid gland does not cause.

Es vermag also der Formaldehyd den Schilddrüsensaft zwar zu sterilisiren und ungerinnbar zu machen, er hebt aber trotz seiner sonstigen antiseptischen Eigenschaften die eigentümliche Toxicität des Saftes nicht auf.So the formaldehyde can indeed sterilize the thyroid juice and cannot coagulate it to make, but despite its other antiseptic properties it highlights the peculiar Toxicity of the juice does not arise.

Dadurch unterscheidet sich der mit Formaldehyd behandelte Schilddrüsenextract charakteristisch von den Protogenen.This distinguishes the thyroid extract treated with formaldehyde in a characteristic way from the protogens.

Das Verfahren der Darstellung ist folgendes:The method of presentation is as follows:

Gut zerkleinerte Schilddrüsen werden so lange mit Formaldehydlösung (ι :200ο) extra-, hirt, bis keine nennenswerthen Mengen mehr in Lösung gehen. Nunmehr wird im Vacuum eingeengt, bis die Lösung etwa 1 g trockenes Schilddrüseneiweifs in 50 ecm Flüssigkeit enthält. Well-shredded thyroid glands are so long with formaldehyde solution (ι: 200ο) extra, until no more significant quantities go into solution. Now is in the vacuum concentrated until the solution contains about 1 g of dry thyroid protein in 50 ecm of liquid.
