Surgical standards before antiseptics starkly contrasted to the surgical art today. Conditions were especially atrocious for amputations and for compound fractures in which the bones penetrated the skin and were exposed to the air. Patients who did not die from the surgery often died of postsurgical infections and subsequent blood poisoning. James Young Simpson, a Scottish surgeon and obstetrician who was the first to use chloroform as an anesthetic (see chapter 7), once said of surgical operations: “A man laid on the operating table in one of our surgical hospitals is exposed to more chance of death than the English soldier on the battlefield of Waterloo.” The mortality rate in hospitals after surgeries was 40–60%. During the American Civil War, the surgical fatalities were just as horrific as those from combat. A commonly used antiseptic in the battlefield was exceedingly corrosive nitric acid (HNO3— ouch!). However, in 1867, Joseph Lister’s use of carbolic acid, whose chemical name is phenol, as an antiseptic changed the prospect of surgery. In Greek, septic means “rotten.” Antiseptics, in turn, are substances used to treat a person to prevent the occurrence of infection. They are also known as germicides. Joseph Lister (1827–1912) was born to a Quaker family in southern England. His father, Joseph Jackson Lister, was a wine merchant and a wellknown microscopist. In his youth, Joseph Lister practiced surgery under the tutelage of James Syme in Edinburgh and married Agnes, his mentor’s daughter. He had to give up his religion because Quakers at that time did not allow marriages outside the faith. That turned out to be a worthwhile sacrifice, because his marriage brought him lifelong joy. Lister became a surgeon at Glasgow Royal Infirmary in 1860. He was acutely conscious of the appalling conditions in the infirmaries and determined to do something about postsurgical infections. In 1865, Lister was introduced to Louis Pasteur’s exploits with germs by Thomas Anderson, chair of the chemistry department at Glasgow. Afterward, he personally repeated all the experiments that Pasteur published. However, simple and direct applications of the Pasteurization process would not be ideal during surgery—after all, boiling patients would not be acceptable.

This paper proposes a new method to discriminate vascular conditions from changes of biological signals and arterial wall impedance using a neural network. Since strong individual differences cause difficulty in discriminating the vascular conditions, we introduce an impedance ratio of the arterial wall and attempt to discriminate the vascular conditions during surgical operations. From experimental results, it is shown that various stimulations during operations cause changes in the impedance parameters of the arterial wall, and vascular conditions such as vasodilation, vasoconstriction, and shock can be discriminated accurately using the proposed method. This method will be useful for monitoring the vascular conditions during operations.

A new method of performing Oriental diagnosis using Meridian Imbalance Diagram which, consisting of 23 different ratios, has a highly discriminatory significance. Using this method, Oriental and Western diagonsis in the same patients were compared. To do this we compared the Meridian Imbalance Diagrams of 22 patients entering our hospital for surgical operations with those 19 in a healthy control group. Four significantly different ratios became evident. The postoperative reports showed that 10 of the patients were suffering from stomach cancer. The Oriental diagnosis data of this new group were then compared to the data of the control group. This time, 10 ratios were found to be significantly different. This shows the existence of a pattern of Oriental diagnosis corresponding to a specific Western diagnosis.

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
