RESUMO

Total soluble sugar, reducing sugar, non-reducing sugar and starch contents of wheat, maize and sorghum grains were affected adversely at 25, 50 and 75 percent insect infestation caused by Trogoderma granarium Everts and Rhizopertha dominica Fabricius, separately and mixed population. R. dominica caused significant (P < 0.05) reduction in available carbohydrates at 50 and 75 percent. Mixture of both insect species caused intermediate losses. Storage of cereal grains up to 4 months resulted in substantial increase in sugars and decrease in starch content, but storage for a shorter period of time did not cause any significant changes in levels of carbohydrates (Summary)

RESUMO

Hemoglobin O Arab (O2á2 121 Glu leads to Lys) was found in 25 members of four apparently unrelated Negro families in the West Indian island of Jamaica. In each family the propositus had Hb SO disease. Two cases had been mistakenly diagnosed as Hb SC disease. Two persons heterozygous for both Hb C and Hb O Arab were found in these families, and Hb O Arab á thalassemia in one other relative. The clinical course and symptomatology of Hb SO disease is comparable to that in Hb SD(O2á2 121 Glu leads to GluNH2) disease and more severe than Hb SC disease. In vitro mixtures of Hb O Arab and Hb S change from a liquid to a gel phase at total hemoglobin concentrations weaker than those required to gel pure Hb S, whereas mixtures of Hb C require a stronger total hemoglobin concentration before gelling will occur. Oxygen dissociation studies on red cells containing Hb SO show a homozygous sickle-cell anemia and outside the range for subjects with sickle-cell Hb C disease.(AU)
