RESUMO
Infection by Echinococcus granulosus is the main zoonosis affecting the human population of the IXth Region in southern Chile. Prevalence rates vary from 18.2 to 48 per 100,000. Animals are affected with prevalence rates of 40% for bovines, 39.5% for sheep and 14.8% for pork as estimated at the central meat processing plant in the city of Temuco. A cost of approximately $300,000 is estimated to treat affected individuals. Much greater losses may be estimated from unnotified meat processing in rural areas and from reduced yield of animal products such as wool an milk. Accordingly, a regional program for control of this zoonosis is urgently required.

Chronaxie, rheobase, conduction velocity and nerve accommodation of 50 alcoholic subjects were studied by applying rectangular and exponentially rising currents to the median nerve. A statistically significant decrease in nerve accommodation indexes and a change in the slope of the accommodation curve were found. The results show that nerve accommodation is more sensitive than other excitability parameters and should be used in the diagnosis and prognosis of alcoholic neuropathies.
