Effects of Catuaba Cristal (R) on the Testis of Wistar rats

The aim of this study was to evaluate the possible beneficial effects of Catuaba Cristal (R) (CC), an alcoholic drink made from wine and Erythroxylum catuaba Ar. Cam on testis. Wistar rats either received CC solution (n=8) or water (n=9). Results showed significant body weight reduction within the CC group, although, no weight changes were observed for liver, kidney, testis, epididymis, seminal vesicle and prostate. The volumetric proportion and volume of interstitial tissue and lymphatic space were reduced in the treated group. In the CC group, although the nuclear volume of Leydig cells (LC) decreased, the number of LC per testis increased. These results suggested that CC had no beneficial effect on spermatogenesis of Wistar rats.545901906Fundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG

The effects of Tynnanthus fasciculatus (Bignoniaceae) infusion on testicular parenchyma of adult Wistar rats

Traditional medicine provides strong guidance for scientific experiments involving plant products used by the Brazilian people. The species "cipo-cravo" (Tynnanthus fasciculatus) is a plant commonly used either to combat indigestion and stomachaches, or as a general stimulant and aphrodisiac. In this study, the effects of "cipo-cravo" infusion were investigated within the testicular parenchyma of adult Wistar rats. Rats were divided into 3 groups: a control (distilled water) and two treated groups, which received the plant infusion (100 and 200mg/animal/day). The 200mg dose promoted a significant increase of the testicular parenchyma weight and of the volume and total length of the seminiferous tubules, as well as in total daily sperm production and sperm production per gram of testis.434445450Fundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG)FAFILE/UEMG (Fundacao Fafile de Carangola
