Hanaoka Seishū
was a Japanese surgeon of the Edo period with a knowledge of Chinese herbal medicine, as well as Western surgical techniques he had learned through ''Rangaku'' (literally "Dutch learning", and by extension "Western learning"). Hanaoka is said to have been the first to perform surgery using general anesthesia. History Hanaoka studied medicine in Kyoto, and became a medical practitioner in Wakayama prefecture, located near Osaka, where he was born. Seishū Hanaoka learned traditional Japanese medicine as well as Dutch-imported European surgery. Due to the nation's self-imposed isolation policy of ''Sakoku'', few foreign medical texts were permitted into Japan at that time. This limited the exposure of Hanaoka and other Japanese physicians to Western medical developments. Perhaps the most notable Japanese surgeon of the Edo period, Hanaoka was famous for combining Dutch and Japanese surgery and introducing modern surgical techniques to Japan. Hanaoka successfully operated for hyd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinese Herbology
Chinese herbology () is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A ''Nature'' editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action. The term herbology is misleading in the sense that, while plant elements are by far the most commonly used substances, animal, human, and mineral products are also utilized, among which some are poisonous. In the ''Huangdi Neijing'' they are referred to as () which means toxin, poison, or medicine. Paul U. Unschuld points out that this is similar etymology to the Greek '' pharmakon'' and so he uses the term "pharmaceutic". Thus, the term "medicinal" (instead of herb) is usually preferred as a translation for (). Research into the effectiveness of traditional Chinese herbal therapy is of poor quality an ...

Records Of Three Kingdoms
The ''Records or History of the Three Kingdoms'', also known by its Chinese name as the Sanguo Zhi, is a Chinese historical text which covers the history of the late Eastern Han dynasty (c. 184–220 AD) and the Three Kingdoms period (220–280 AD). It is widely regarded as the official and authoritative source historical text for that period. Written by Chen Shou in the third century, the work synthesizes the histories of the rival states of Cao Wei, Shu Han and Eastern Wu in the Three Kingdoms period into a single compiled text. The ''Records of the Three Kingdoms'' is the main source of influence for the 14th century historical novel ''Romance of the Three Kingdoms,'' considered one of the great four novels of Chinese classical literature. Major chunks of the records have been translated into English, but the tome has yet to be fully translated. Origin and structure The ''Records of the Grand Historian'', ''Book of Han'' and '' Book of the Later Han'', and the ''Re ...

Hua Tuo
Hua Tuo ( 140–208), courtesy name Yuanhua, was a Chinese physician who lived during the late Eastern Han dynasty. The historical texts ''Records of the Three Kingdoms'' and ''Book of the Later Han'' record Hua Tuo as the first person in China to use anaesthesia during surgery. He used a general anaesthetic combining wine with a herbal concoction called ''mafeisan'' (; literally "cannabis boil powder"). Besides being respected for his expertise in surgery and anaesthesia, Hua Tuo was famous for his abilities in acupuncture, moxibustion, herbal medicine and medical Daoyin exercises. He developed the ''Wuqinxi'' (; literally "Exercise of the Five Animals") from studying movements of the tiger, deer, bear, ape and crane. Historical accounts The oldest extant biographies of Hua Tuo are found in the official Chinese histories for the Eastern Han dynasty (25-220) and Three Kingdoms period (220-280) of China.

Amputation
Amputation is the removal of a limb by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventive surgery for such problems. A special case is that of congenital amputation, a congenital disorder, where fetal limbs have been cut off by constrictive bands. In some countries, amputation is currently used to punish people who commit crimes. Amputation has also been used as a tactic in war and acts of terrorism; it may also occur as a war injury. In some cultures and religions, minor amputations or mutilations are considered a ritual accomplishment. When done by a person, the person executing the amputation is an amputator. The oldest evidence of this practice comes from a skeleton found buried in Liang Tebo cave, East Kalimantan, Indonesian Borneo dating back to at least 31,000 years ago, where it was done whe ...

Necrosis
Necrosis () is a form of cell injury which results in the premature death of cells in living tissue by autolysis. Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, apoptosis is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always detrimental and can be fatal. Cellular death due to necrosis does not follow the apoptotic signal transduction pathway, but rather various receptors are activated and result in the loss of cell membrane integrity and an uncontrolled release of products of cell death into the extracellular space. This initiates in the surrounding tissue an inflammatory response, which attracts leukocytes and nearby phagocytes which eliminate the dead cells by phagocytosis. However, microbial damaging substances released by leukocytes would cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oral Cancer
Oral cancer, also known as mouth cancer, is cancer of the lining of the lips, mouth, or upper throat. In the mouth, it most commonly starts as a painless white patch, that thickens, develops red patches, an ulcer, and continues to grow. When on the lips, it commonly looks like a persistent crusting ulcer that does not heal, and slowly grows. Other symptoms may include difficult or painful swallowing, new lumps or bumps in the neck, a swelling in the mouth, or a feeling of numbness in the mouth or lips. Risk factors include tobacco and alcohol use. Those who use both alcohol and tobacco have a 15 times greater risk of oral cancer than those who use neither. Other risk factors include HPV infection, chewing paan, and sun exposure on the lower lip. Oral cancer is a subgroup of head and neck cancers. Diagnosis is made by biopsy of the concerning area, followed by investigation with CT scan, MRI, PET scan, and examination to determine if it has spread to distant parts of the body ...

Breast Cancer
Breast cancer is cancer that develops from breast tissue. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin. Risk factors for developing breast cancer include obesity, a lack of physical exercise, alcoholism, hormone replacement therapy during menopause, ionizing radiation, an early age at first menstruation, having children late in life or not at all, older age, having a prior history of breast cancer, and a family history of breast cancer. About 5–10% of cases are the result of a genetic predisposition inherited from a person's parents, including BRCA1 and BRCA2 among others. Breast cancer most commonly develops in cells from the lining of milk ducts and the lobules that supply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Surgery
Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic (or aesthetic) surgery aims at improving the appearance of it. Etymology The word ''plastic'' in ''plastic surgery'' means "reshaping" and comes from the Greek πλαστική (τέχνη), ''plastikē'' (''tekhnē''), "the art of modelling" of malleable flesh. This meaning in English is seen as early as 1598. The surgical definition of "plastic" first appeared in 1839, preceding the modern "engineering material made from petroleum" sense by 70 years. History Treatments for the plastic repair of a broken nose are first mentioned in the Egyptian medical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fistula
Anal fistula is a chronic abnormal communication between the epithelialised surface of the anal canal and usually the perianal skin. An anal fistula can be described as a narrow tunnel with its internal opening in the anal canal and its external opening in the skin near the anus. Anal fistulae commonly occur in people with a history of anal abscesses. They can form when anal abscesses do not heal properly. Anal fistulae originate from the anal glands, which are located between the internal and external anal sphincter and drain into the anal canal. If the outlet of these glands becomes blocked, an abscess can form which can eventually extend to the skin surface. The tract formed by this process is a fistula. Abscesses can recur if the fistula seals over, allowing the accumulation of pus. It can then extend to the surface again – repeating the process. Anal fistulae ''per se'' do not generally harm, but can be very painful, and can be irritating because of the drainage of p ...

Hydrocele
A hydrocele is an accumulation of serous fluid in a body cavity. A hydrocele testis, the most common form of hydrocele, is the accumulation of fluids around a testicle. It is often caused by fluid collecting within a layer wrapped around the testicle, called the tunica vaginalis, which is derived from peritoneum. Provided there is no hernia present, it goes away without treatment in the first year. Although hydroceles usually develop in males, rare instances have been described in females in the Canal of Nuck. Primary hydroceles may develop in adulthood, particularly in the elderly and in hot countries, by slow accumulation of serous fluid. This is presumably caused by impaired reabsorption, which appears to be the explanation for most primary hydroceles, although the reason remains obscure. A hydrocele can also be the result of a plugged inguinal lymphatic system caused by repeated, chronic infection of ''Wuchereria bancrofti'' or ''Brugia malayi'', two mosquito-borne parasi ...
