Gumma

a prefecture in Japan, in the central part of Honshu. Area, 6,300 sq km. Population, 1.6 million (1968), 56 percent urban. Its administrative center is the city of Maebashi. The prefecture is situated on the southeast slope of the Etigo volcanic range, which reaches an altitude of 2,578 m, and on the adjacent parts of the Kanto plain near the Tone River. On the mountain slopes there are fir forests. The rivers of the area have great hydroelectric potential.

Gumma is part of the Kanto economic region. Of the economically active part of the population (about 50 percent, or 812,000), 33 percent are involved in agriculture, 25 percent in processing industries, 15 percent in commerce, and 12 percent in service occupations. In the postwar period, there has been a trend away from an agriculturally specialized economy to a more industrial-agrarian one. The leading branches of industry, in terms of percentage of the total monetary value of production of the prefecture, are as follows: food-processing (16.5 percent), textiles (16 percent), electric machine building (13 percent), and transport machine building (13 percent). Manganese ore is mined, and potassium nitrate is extracted from the craters of extinct volcanoes. Another important branch of the economy is silk culture, which involves 30,000 hectares and provides 24 percent of Japan’s production of silk cocoons. A total of 120,000 hectares is under cultivation, of which 40 percent is used for rice cultivation (160,000 tons harvested per year). Horticulture and timber are also important.

gum·mas

(gŭm'ă, ă-tă, -ĕz), An infectious granuloma that is characteristic of tertiary syphilis, but does not always develop, and that may be solitary (as large as 8-10 cm in diameter) or multiple and diffusely scattered (1 mm or less in diameter). Gummata are characterized by an irregular central portion that is firm, sometimes partially hyalinized, and consisting of coagulative necrosis in which "ghosts" of structures may be recognized; a poorly defined middle zone of epithelioid cells, with occasional multinucleated giant cells; and a peripheral zone of fibroblasts and numerous capillaries, with infiltrated lymphocytes and plasma cells. As gummas become older, an irregular scar or rounded fibrous nodule persists. Synonym(s): syphiloma [L. gummi, gum, fr. G. kommi]

gumma

One of the principle features of late (tertiary) SYPHILIS. The gumma is a localized mass of GRANULATION TISSUE, with a necrotic centre of a gum-like consistency. It occurs as a result of toxic destruction of tissue and can occur anywhere in the body, including the intestines, the liver and the brain.
