Ofloxacin presents an ample spectrum of antimicrobial action, including combating Mycobacterium leprae, and is currently employed as a substitute when the use of rifampicin is impossible. The objective of this work was to study alterations in testicular cell nuclei of suckling rats, whose dams were submitted to oral application of ofloxacin, and respective control groups. The method utilized was morphometry by the karyometric technique. The main structures observed in histological preparations of the testicles were interstitial cells, spermatogonias, and sustentacular cells. 10 Wistar rats were utilized, four treated and five controls, in the period of the first 25 days of life, whose dams received ofloxacin 12 mg/ Kg of body weight / day orally, before...

This study evaluated the structure and the volume of interphase nuclei from root meristems of the genotypes of napier grass (Pennisetum purpureum), pearl millet (Pennisetum glaucum) and hybrids resultant of such breeding. In napier grass, nuclei were areticulate. Both pearl millet and the triploid hybrid had semi-reticulate nuclei; also, the hybrid presented a small proportion (6%) of areticulate nuclei. Pearl millet had the highest averages of nuclear dimensions, such as volume, diameter and radius, followed by the interspecific hybrid and napier grass. There was no intraspecific variation for the type of nuclear structure, which indicates this feature is important for cytotaxonomic studies involving the genus Pennisetum. Results demonstrated that...
