Avaliação do efeito hipoglicemiante de Cissus sicyoides em estudos clínicos fase II

2008 
This study aimed to perform Phase II clinical trials with the infusion of the leaves of Cissus sicyoides L to investigate its therapeutic effectiveness in glucose-intolerant (GIG n = 14) and in type 2 diabetic (GD n = 12) volunteers, 30 to 59 years old, at Hospital Universitario Lauro Wanderley/UFPB. The tea was prepared with 1g of dust falling leaves diluted in 150 mL of hot water for 10 minutes (popular usage), in single doses, for 7 days (acute phase). In the GIG, the interaction between the glicemy and the insulin was verified through two oral tests of glucose tolerance, with and without infusion’s ingestion. The glicemy and the insulinemy were determined at 0, 1, 2, and 3 hours. For GD, the spontaneous variation of glicemy (during fasting and resting periods, at 0, 1, 2, and 3 hours), and the glicemic profile (before and 2 hours after meals) were evaluated in the absence and in the presence of the tea. For GIG, the tea of the leaves revealed considerable hypoglycemic activity at 120 minutes; however there was no insulinemy increase, beyond the physiological, suggesting that this effect did not happen because of insulinemy’s liberation or secretion. For GD, the tea did not demonstrate considerable hypoglycemic activity.
