| Buchenavia tomentosa Eichler is a common plant in Brazilian cerrado. Fruits of this plant are employed in human feeding and folk medicine. Cattle producers affirm that consumption of the fruits cause abortion in cows, and even death. Considering that the plant may be consumed by pregnant women and animals, the present study was undertaken to evaluate the possible toxic effects of the ingestion of B. tomentosa fruit (10% added to the diet), from the first to the twenty-first days of gestation, on reproductive parameters and on physical and neurobehavioral development of rats offspring. An increase in food consumption at pregnancy days 11 and 17, and weight increase at day 17 of pregnancy were observed. Besides that, we verified an increase in weight of... |

| The aim of the present study was to evaluate the effects of sodium fluoride (NaF) on the male reproductive system. Adult male rats were exposed to NaF in drinking water for 30 days at three concentrations: 1.54 (control, tap water), 50 and 100 ppm. Body and organ weights, daily sperm production, sperm number and morphology were investigated. No difference was observed on the sperm number and morphology among the groups, as well as body weight and organ absolute and relative weights. Overall, despite the presence of a mild degree of dental fluorosis in the higher dose group, the results indicated that exposure to NaF at the doses used in the present study did not adversely affect sperm production and morphology of male rats. |

| The objective of this study was to evaluate the effects of boron (B) using as a biological model Drosophila malanogaster. Analizing specifically the responses over descendency to doses of 6,0 and 12 mg/L, comparing a control group which culture medium was prepared with water with boron concentrations of 0,6 mg/L, according to World Health Organization. The results show a significative alteration in the number of descendency from F1 to F3 and then a tendency to normalization in F4 and F5. Also a significant change in proportions between the males and females, with an acute effect on F1 and then a possible chronic effect from F2 to F5, increasing the proportion of females over males. This differences between genders are significant only until F4, on F5 these... |

| ABSTRACT Gossypol, a phenolic compound produced by the pigment glands of cotton, is known to affect male reproduction. In females, exposure to gossypol has been associated with interference with the estrous cycle and embryo development. In laying hens fed cottonseed, gossypol was found to reduce egg production and weight and to cause discoloration of the egg yolk and/or albumen. It is probable that gossypol directly affects ovarian follicles, but this has not been confirmed experimentally yet. Thus, the aim of the present study was to determine if gossypol affected cultivated ovarian follicles of the chicken. Ovarian follicles of adult female chickens were cultivated with different concentrations of gossypol (0, 5, 10 and 20 μg/mL) and classified according... |
