It is curious that so little was praziquantel online done toward the study of the intestines in the early davs, for their ajipearance ninsi Ikivc been quite fan'iiliar to the 374 IIIHLSCHER: THE APPEXDIX .IXU ITS DISEASES. (Nkw York KinCAL Journal. priests who offered sacrifices, because their duly was to inspect them for omens, and observe that they were in a health)' condition ; for the gods were supposed to abhor disease in praziquantel price any of their victims. War also of the kind that was waged in early days must have often e.xposed them in the living human subjects, and the custom of embalm- ing afforded the Egyptian priests, who were also the physicians, great opportunity for their study, as the intestines were removed from the body cav- ity in order that it might be tilled with spices. Yet no advances seem to have been made in their study. ^\s a matter of fact, the intestines were looked on merely as tubes for reception of waste matter, and quite beneath the notice of the scientist. Cicero, in his De Xattira Deorum, informs the reader thit "he knows the alimentary purchase praziquantel canal, but order praziquantel online from motives of delicacy omits the details," and Boerhaave, writ- ing in the seventeenth century, prefaces his chapter on the praziquantel tablets e.xpulsion of the feces in the Institutes and Comments with this apology, "now we come to a nasty, but necessary part of the business,'' though he traced the food moxidectin praziquantel through the upper part of the tract apparently without shame. This feeling as to the inferiority of the intestines may account for the neglect that was their portion until they ex- praziquantel 600 mg alted themselves by disease to that "bad eminence'" which they occupy at the present time. \'esalius died in 1564, and a little more than a century afterward, Boerhaave was born ( 1668) . During the period between \'esalius and Bcerhaave many independent searchers sprang up, some of them of such transcendent genius that their light shines even to this day. There were Eustachius. the contemporary of Vesalius, whose beautiful an- atomical plates are still the delight of the anatom- ist's heart, and which he was, alas, too poor to have the jov of seeing published in his lifetime: Fallopius, the pupil of \''esalius, and \'arolius, the physician of Gregory the Thirteenth, whose name lives In the "pons Varolii." Then, there was the priest Servetus, whose deplorable death at the stake set back the discovery of the circulation of the blood at least half a century ; Harvey, who de- scribed this in 1600. and Fabricius, his teacher, praziquantel uk whose observation of the valves in the veins of the lower extremities must have been such an aid to his brilliant pupil. It was about this time that an interest began to l)e manifested in the intestines, delicately at first. "Wie die Katze um den heissen Brei." They be- ;.;an with the mesentery, and the upper or more honorable parts of the tract. It should be remem- bered that there was already some work done on the where to buy praziquantel mesentery as early as 270 B. C, for Erastratus and Hierophilus described the white buy praziquantel vessels, or lacteals. in the living kid. and the recep- taculum chyli generic praziquantel and thoracic duct in the horse, named the twelve inch portion of the intestines and noticed the likeness of the convolutions of the jejunum to those of the brain. In 1637 High- more was able to distinguish between the lac- teals and the mesenteric veins. Some time after- ward Olaus Rudbeek distinguished the lacteals from the lymphatics, describing for the first time the latter order of vessels. In 1652 this 3'oung anatomist traced the lymphatics to the thoracic duct and hence to ihe subclavian vein, in a iiublic dem- onstration before Christina, queen of Sweden. It .seems to have been a custom of those times to make public demonstrations of any newly acquired knowledge, as if a victory that concerned every- lx)dy had been won over ignorance. This practice did not fail to bring glory to the individual, hut was not order praziquantel without its dangers, for Wirsung was enviously assassinated on the evening of the day upon which he demonstrated so beautifully the pan- creatic duct. Peyer and P>runner were at work praziquantel biltricide also about this time, and with the aid of the mi- croscope, that Leeuwenhoek was bringing to a high stage buy praziquantel online of usefulness, they opened up new fields to both the anatomist and the physiologist. Then Ruysch was pursuing his methods of research by injecting the hollow chambers of the buy praziquantel for humans body, so that it was said praziquantel cost of him that "nothing in the human economy escaped his pipette." The advent of Boerhaave into the scientific world marks an epoch in the development of knowledge concerning the appendix, for he was the first to give it the dignity of physiological utility. His de- scription is confined to a few lines, and his physi- ology is incorrect : yet his buy cheap praziquantel teachings are of such a nature as to make them highly important. Boer- haave himself is a striking figure in an important era. He was professor in the University of Ley- den when that institution was at the height of its glory. His fame drew students from all parts of the world. Peter the Great, of Russia, spent some time in his classes. His contemporaries were Val- salve, Santorini, and Morgagni. Yon Haller was for some time his pupil, and he collaborated w'ith the brilliant young Xuck, of whom he writes : "I praziquantel mg have seen him more than a hundred times spread out the mesentery on a table, and. with a steel tube inserted into the least of the lymphatics, demon- strate the whole system." Boerhaave's standing, and his place in the scientific world, is gone into here in order that due weight may be given purchase praziquantel online to his teachings, and that an ignorance of his subject may not be suggested as an excuse for the contradiction
