十四世紀,鼠疫襲擊東羅馬的首都君士坦丁堡。當時大規模的十字軍東征和日趨頻繁的商貿往來,將這場鼠疫迅速傳到了整個歐洲。在義大利,佛羅倫斯死掉了2/3 的居民,威尼斯死掉了3/4 (十萬人),。在法國,死掉了總人口 3/4,在亞威農,隆河被丟棄的屍體弄得擁塞不通。


Disease: dis (否定); ease (身心安樂)

  • 疾病的象形字,甲骨文中已經出現。疾,據《殷虛文字乙編》考“象矢著人腋下…知此亦疾字…按疾古訓急,訓速,最速者莫如矢,故從人旁矢,矢著人斯為疾患,故引申訓患、訓苦…”;另:卜辭有兩個字,前者像人臥於床上,後者像人在床上冒汗,釋作疾。若釋病應當也不錯,因為《說文》二字互訓:“疾,病也。”“病,疾加也。”只是疾病程度和分析的眼光不同罷了 (別人說的話)。

疾病是什麼: 不變的兩千年

  • 左昭元年 (541 B.C.)引醫和云:「天有六氣,降生五味,發為五色,徵為五聲,淫生大疾。六氣曰:陰、陽、風、雨、晦、明也。……陰淫寒疾,陽淫熱疾,風淫末疾,雨淫腹疾,晦淫惑疾,明淫心疾。」
  • 清代台灣歷史文獻中 (around 1800 A.D.),即常用「瘴」、「 瘴氣」和「瘴癘」等語詞,記載這些因地方環境條件而引 起的疾病。

  • Homer’s Iliad (800 B.C.) begins with a plaque sent by Apollo on the Greeks.
  • The arrows of Apollo and Artemis are often a symbol for the sudden onset of disease.

The plague doctor in clothing worn to protect from contagion, circa 1656. We are haunted by images of the horrors of disease and death, but with the current influx of data from microbial genomes, we can expect some answers to questions about how microorganisms have evolved, causing much fear. Apart from using these data to design new drugs and vaccines, we can also explore what the molecular signature of a microorganism may mean to a host population and predict more precisely the effects of intervention (2001A.D.).

在英國,英國女王伊麗莎白一世 (1558),帶著手下一干人馬逃到北部的溫莎避難,並在溫莎一帶豎起很多絞刑架,下令凡是抓到從倫敦來的人,一律格殺勿論。

  • 教會告誡人們這是上帝的懲罰,救贖的方法只能是懲戒撒旦的幫兇與集體贖罪。猶太人得黑死病的比率低(猶太人的「潔淨」觀念)─在上帝面前保持道德和身體的潔淨。但是基督徒,卻認為是猶太人和魔鬼合謀製造出災難。反猶太人暴動的結果是:沒有死於黑死病的猶太人,卻死在鄰居的刀下。二百多個猶太社區被摧毀,無數人被燒死。



Disease in religion

"I will say this: because these experiences I had were so tremendous, God was afraid I might be puffed up by them; so I was given a physical condition which has been a thorn in my flesh, a messenger from Satan to hurt and bother me and prick my pride. Three different times I begged God to make me well again. Each time he said, "No. But I am with you; that is all you need.

Theology and biology

  • 有些宗教….,還提出了一套有別於世俗醫學的疾病觀和治療方法。他們大多強調,人之所以生病,主要起因於道德上的敗壞和鬼神的責罰,因此,治療方法也偏重於懺悔、祭禱、齋醮、功德這一類的宗教療法,或是以符咒、厭勝為主的巫術療法。此外,他們也採納食療、沐浴、按摩、導引、房中之類的養生術。對於世俗的醫學,他們有時會加以貶抑或拒斥,但是,通常都會兼容並蓄。
  • 若從病人的角度來看,我們發現,宗教信仰似乎可以緩解病人在心理和道德上的焦慮和不安,而傳統中國及台灣社會面對瘟疫流行的因應之道,除了醫療救助之外,往往也採取政治改革、社會救濟和道德重整。

  • 桑塔格(Susan Sontag,美國的良心)2004年病逝。《疾病的隱喻》(Illness as Metaphor) 發表於1978年,自身離癌的桑塔格不滿意隱藏在癌症背後的文化隱喻,這使她非得要揭開隱喻不可(p.114-115)。而隨後,當愛滋病在八十年代取代癌症,成為各隱喻的對象後,桑塔格又寫了一篇『愛滋及其隱喻』(AIDS and Metaphors)。由大田出版的中文版同時收錄了這兩個篇章。

They were asking not "Who causes this sickness?" but rather, "By what process does this sickness occur?" However imaginative their mechanistic explanations may be, Hippocratics can defend them with arguments that appeal to process, not to a capricious or malevolent deity, and they can explain the therapies they prescribe in terms of the actions that their medicaments set in motion.

Hippocrates: Greek physician on the island of Cos, Greece : 460 BC-377 BC.

  • Hippocrates began teaching that every disease had only natural causes. He was the first physician known who actually considered medicine to be a science, and to be separate from religion.
  • He described many illnesses including pneumonia, * tetanus, * tuberculosis, * arthritis, * mumps, * and malaria *

Giovanni Battista Morgagni (1682-1772)

Morgagni showed beyond any doubt that specific disorders cause suffering and death. We find a ruptured appendix, syphilis of the aorta, and epidural hematoma. A lifetime of compassion and clear thinking lies behind this chamber of horrors.

Percussion: 敲診

Auenbrugger, Leopold, 1722–1809, Viennese physician. His findings on the use of percussion in diagnosing chest diseases were published in 1761 (tr. On Percussion of the Chest, 1936). Although ignored for some 40 years, his method, revived by Jean Nicolas Corvisart, was ultimately generally adopted.

中國的診法與辨證, 存而不論???

中醫在診斷上以"四診"(望, 聞, 問, 切)作為基本的診察方法。 以"八綱"(陰, 陽, 表, 裏, 虛, 實, 寒, 熱)作為辨證的綱領。 並結合氣血辨證, 六經辨證, 臟腑辨證, 經絡辨證, 三焦辨證, 等作為判斷疾病原因, 部位, 性質的主要方法, 從而為治療提供依據。

"The contagiousness of childbed fever": a short history of puerperal sepsis and its treatment; by Caroline M De Costa

For lecture only , BC Yang


Ignac Semmelweis

a native of Hungary

In 1844, Semmelweis was appointed assistant lecturer in the First Obstetric Division of the Vienna Lying-In Hospital, the division in which medical students received their training. He was appalled by the division's high mortality rate from puerperal fever — 16% of all women giving birth in the years 1841–1843. In contrast, in the Second Division, where midwives or midwifery students did the deliveries, the mortality rate from the fever was much lower, at about 2%. Semmelweis also noted that puerperal sepsis was rare in women who gave birth before arriving at the hospital

It is always hard for anyone to admit they are wrong. "Okay, so I was wrong about the Cubs winning the pennant." Not so hard to admit. But if the item is central to your profession, and admitting it not only questions your judgment but implicates you, although at the time unknowingly, in the many deaths your error has caused, that is a little harder to swallow. Obviously, many would, and did, deny the error rather than face the upset.

The Doctors' Plague by Sherwin B. Nuland

Semmelweis wrote a series of “open letters” to his former professors, accusing them — rightly, as it turned out — of being “medical Neros” and “murderers”. (錯誤的策略)

In 1866 Joseph Lister (1827-1912) suggested antiseptic surgery. His rational was:

  • Putrefaction is caused by microbes
  • Wound sepsis is a form of putrefaction
  • Wound sepsis is caused by microbes (未指名)

Joseph Lister was ridiculed, criticized, and harassed. The medical community didn’t like having its status quo questioned. The nurses regarded Lister’s procedures as eccentric, and they resented the extra work his obsessions with cleanliness were causing. The doctors were angered at the implication they were responsible for some of the deaths.
  • Louis Pasteur and Joseph Lister were personal friends and supported each other when the medical community viciously attacked them. Sometimes they felt they were alone in their struggles to bring the truth to light. People were needlessly dying, and it seemed nobody was listening.

  • In the medical field Redi promoted a reform of therapeutical methods recommending natural procedures (diet, purges and clysters) to purify the body of impurities, according to the Hippocratic rules.
  • The origin of scabies from mites, demonstrated by Giovan Cosimo Bonomo and Giacinto Cestoni. It was in fact Redi who published the Osservazioni intorno a' pellicelli del corpo umano (Observations On The Worms Of The Human Body) in 1687, with Bonomo's name only. This work proved that the disease was caused by a microscopic worm which introduced itself by laying eggs under the patient's skin. This discovery was a "Copernican revolution" in the history of pathology, since it shifted the attention of physicians from the sick subject to the pathological agent and suggested new therapeutic methods in the treatment of infectious diseases.

  • Redi entlarvte die jahrtausendealte Theorie über die Urzeugung der Insekten durch ein epochemachendes Experiment als falsch, und führte zugleich eine völlig neue Methode der Forschung in die Wissenschaft ein.
  • Diese Methode, bis heute die Grundlage der experimentellen Biologie, besteht darin, dasselbe Experiment auf verschiedene Weise durchzuführen, indem jeweils nur ein "Parameter", eine Bedingung, geändert wird, und zugleich passende Tests durchgeführt werden.

By making photomicrobiographs, I can reveal the bacteria true to nature and free of subjective misinterpretation

---Rober Koch


Privy Health Officer

Berlin W, 15, June 30, 1904

Dear Sir, I still remember very well the first time I took an oil system into my hands and myself witnessed the dramatic progress achieved by the optical workshop of Carl Zeiss under the direction of Professor Abbe's ingenious advisory board. Every time I subsequently used oil systems, I thought with admiration and gratitude of the magnificent gift made by the Zeiss optical workshop to everyone working with a microscope. After all, I owe a large percentage of the success I have had the privilege of achieving for science to your excellent microscopes which were of enormous benefit to me in the expedition to South Africa which I have just completed. Respectfully yours, R. Koch

The Amerindians of Mesoamerica and the Caribbean were hard hit by European diseases to which they had no immunity. The predominance of the slave trade in the region added African diseases to the mix, and the climate of the Caribbean was especially well suited to the proliferation of these epidemics. Smallpox, measles, typhus, yellow fever, malaria, tuberculosis, and pus infections decimated the indigenous populations. In 1492 it is estimated that there were approximately 250,000 Arawak and Carib living in the Caribbean. Within twenty years almost all of the indigenous population of the islands had died.





Sherwin B. Nuland 評論達文西

(in: Doctors: the biography of medicine)


"Good education is amongst the rarest things going; difficult to buy at any price“

The Lancet, 1886

The medical schools which developed in London did so in close alliance with the great voluntary hospitals. Private schools attached to the larger hospitals also existed in the provinces, but outside London medical education tended to become an integral part of multi-faculty universities as soon as these developed, in close association with their science departments. In Europe the medical schools also developed within a university milieu. In London, however, the schools were firmly established before the creation of the University of London in 1836. In most cases the school was established after the hospital, and it always had a closer relationship with its allied hospital than with the University.
