On the other hand, I suspect that they fear too broad a dissemination of the Caste knowledge.Physicians, interestingly, perhaps for a similar reason, tend to keep records in archaic Gorean,which is incomprehensible to most Goreans." ~ Magicians of Gor, pg 394

"I was pleased that she would go to Ar, where she,
though a woman, might learn the craft of medicine under the masters appointed by Kazrak ( Kazrak was city administrator of Ar )." ~ Priest Kings of Gor, pg 306

"Though one is commonly born into a Caste one is often
not permitted to practice the caste craft until a suitable apprenticeship has been served." ~ Fighting Slave of Gor, pg 209

"A notable exception to the generalization that woman of a Caste normally do not engage in Caste work is the Caste of Physicians, whose women are commonly trained, as are the boys, in the practice of medicine." ~ Fighting Slave of Gor, pg 210

"On the first day the Physician, a quiet man in the green garments of his Caste, examined me, thoroughly. The instruments he used, the tests he performed, the samples he required were not unlike those of Earth. Further, certain pieces of his instrumentation were clearly far from primitive. For example, there was a small machine with gauges and dials. In this he would place slides, containing drops of blood and urine, flecks of tissue, a strand of hair. with a stylus he would note readings on the machine, and on a small screen at the top of the machine, I saw, vastly enlarged, what reminded me of an image witnessed under a microscope." ~ Captive of Gor, pg 92-93

"At any rate, disease is now almost unknown among the Gorean cities, with the exception of the dreaded Dar-Kosis disease or the Holy disease, research on which is generally frowned upon by the Caste of Initiates, who insist the disease is a visitation of the displeasure of the Priest-Kings on its recipients. The fact that the disease tends to strike those who have maintained the observances recommended by the Caste of Initiates, and who regularly attend their numerous ceremonies, as well as those who do not, is seldom explained, though, when pressed, the Initiates speak of possible secret failures to maintain the observances or the inscrutable will of the Priest-Kings." ~ Assassin of Gor, pg 29-30

"On the other hand, you will learn that in lighting, shelter, agricultural techniques, and medicine, for example, the Mortals, or Men Below the Mountains, are relatively advanced." ~ Tarnsman of Gor, pg 31

"certain pieces of his instrumentation were clearly far from primitive. For example, there was a small machine with gauges and dials. In this he would place slides, containing drops of blood and urine, flecks of tissue, a strand of hair. With a stylus he would note readings on the machine, and, on the small screen at the top of the machine, I saw, vastly enlarged, what reminded me of an image witnessed under a microscope. He would briefly study this image, and then make further jottings with his stylus. The guard had strictly forbidden me to speak to the physician, other than to answer his questions, which I was to do promptly and accurately, regardless of their nature." ~ Captive of Gor

"Flaminius, swiftly wrapping a white cloth about the wound, securing it with four small metal snap clips." ~ Assassins of Gor


Stabilization Serums


"The Player was a rather old man, extremely unusual on Gor, where the stabilization serums were developed centuries ago by the Caste of Physicians in Ko-ro-ba and Ar, and transmitted to the Physicians of other cities at several of the Sardar Fairs. Age, on Gor, interestingly, was regarded, and still is, by the Castes of Physicians as a disease, not an inevitable natural phenomenon. The fact that it seemed to be a universal disease did not dissuade the caste from considering how it might be combated. Accordingly the research of centuries was turned to this end." ~ Assassin of Gor, pg 29

"The Stabilization Serums, which are regarded as the right of all human beings, be they civilized or barbarian, friend or enemy, are administered in a series of injections, and the effect is, incredibly, an eventual, gradual transformation of certain genetic structures, resulting in indefinite cell replacement without pattern deterioration. These genetic alterations. moreover, are commonly capable of being transmitted. For example, though I received the series of injections when first I came to Gor many years ago I had been told by Physicians that they might, in my case, have been unnecessary, for I was the child of parents who, though of Earth, had been of Gor, and had received the serums. But different human beings respond differently to the Stabilization Serums, and the Serums are more effective with some than with others. With some the effect lasts indefinitely, with others it wears off after but a few hundred years, with some the effect does not occur at all, with others, tragically, the effect is not to stabilize the pattern but to hasten its degeneration. The odds, however, are in the favor of the recipient, and there are few Goreans who, if it seems they need the serum’s, do not avail themselves of them." ~ Assassins of Gor, pg 30

“Of course,” said Misk, “but we have allowed them to develop in many areas - in medicine, for example, where something approximating the Stabilization Serums has been independently developed.” 
“What is that?” I asked. 
“You have surely not failed to notice,” said Misk, “that though you came to the Counter-Earth more than seven years ago you have undergone no significant physical alteration in that time.” 
“I have noticed,” I said, “and I wondered on this.” 
“Of course,” said Misk, “their serums are not as effective as ours and sometimes do not function, and sometimes the effect wears off after only a few hundred years.” 
“This was kind of you,” I said." ~ Priest-Kings of Gor, pg 124

"'You spoke of knowing the Cabots for four hundred years,' I said. 'Yes,' said Misk, 'and your father, who is a brave and noble man, has served us upon occasion, though he dealt only, unknowingly, with Implanted Ones. He first came to Gor more than six hundred years ago.' 'Impossible!' I cried. 'Not with the stabilisation serums,' remarked Misk." ~ Priest-Kings of Gor, pg 126
