ABSTRACT
O crescente interesse na substituição de antioxidantes sintéticos por naturais em alimentos tem fomentado a pesquisa sobre fontes vegetais, caracterização de matérias-primas e identificação de novos compostos antioxidantes. As reações de oxidação não são uma preocupação exclusiva das indústrias alimentícias, seu estudo é também amplamente necessário para evitar implicações indesejáveis na saúde humana. O objetivo desta revisão, depois de apresentar aspectos gerais sobre a oxidação, é concentrar-se nos benefícios da utilização das especiarias como antioxidantes naturais, em especial as da família Labiatae, amplamente utilizadas na culinária brasileira.
The growing interest in replacing synthetic antioxidants by natural antioxidants in food has stimulated research on vegetable sources, raw material characterization and identification of new antioxidant compounds. Oxidation reactions are not an exclusive preoccupation of the food industry; studies regarding this issue are widely necessary in order to prevent undesired implications for human health. The aim of this review, after presenting overall aspects about oxidation, is to concentrate on the benefits of using spices as natural antioxidants, especially those from the Labiatae family, which are widely used in the Brazilian cuisine.

CASE REPORT: Gastric cancer in a 29 years old pregnant woman. A total of 109 cases were collected in the whole from 1916 to 1988; to these, we add one new case of a 29 years old pregnant woman observed in 1993 in Verona University Surgical Sciences Department. DISCUSSION: Cancer of the digestive tract during pregnancy is really rare and has poor prognosis. The diagnosis during pregnancy is difficult because the symptoms are frequently masked by factors related to the normal first trimester in pregnancy. X-ray are often restricted. Gastroendoscopy is applied to pregnant women only when evident symptoms are present such as: severe anemia, jaundice and weight loss. The incidence of inoperable cases is elevated such as the mortality in the operated cases. The whole survival rate after three years is 21%. CONCLUSION: Gastric cancer in pregnancy has a poor prognosis. The possible reasons are: delayed detection, low differentiation degree, restricted therapeutic approach because of pregnancy, personal factors as the patients' desire for a child, religious, ethical considerations.
