| MicroRNAs (miRNAs) have been identified in cells as well as in exosomes in biological fluids such as milk. In mammary gland, most of the miRNAs studied have functions related to immunity and show alterations in their pattern of expression during lactation. In mastitis, the inflammatory response caused by Streptococcus uberis alters the expression of miRNAs that may regulate the innate immune system. These small RNAs are stable at room temperature and are resistant to repeated freeze/thaw cycles, acidic conditions and degradation by RNAse, making them resistant to industrial procedures. These properties mean that miRNAs could have multiple applications in veterinary medicine and biotechnology. Indeed, lactoglobulin-free milk has been produced in transgenic... |

| Com o intuito de observar o efeito da aplicação do laser de baixa intensidade sobre a contagem de células somáticas no leite foram selecionadas 12 cabras lactantes mantidas em sistema semi-confinado de criação. Os animais devidamente identificados foram distribuídos aleatoriamente em dois grupos de seis, sendo que um grupo recebeu a aplicação de laser e o outro não. Diariamente, por um período de seis dias consecutivos foi retirada uma amostra de leite por animal, sendo que ao término da terceira, quarta e quinta ordenha foi aplicada uma dose de laser na intensidade de 0,6 J numa área depilada correspondente ao acuponto "Baihui posteior" pressionando-o com um laser de hélio-neônio com uma potência de 10 mW. No planejamento foi definido um delineamento... |

| Cadmium in the air, drinking water and food has the potential to affect the health of people, mainly those who live in highly industrialized regions. Cadmium affects placental functions, can cross the placental barrier and directly disturbs fetal development. It is also excreted into milk. The organism is particularly susceptible to cadmium exposure at perinatal period. The effect on rat maxillary molar junctional epithelium a continuous exposure to drinking water containing low level of cadmium during lactation was studied. Female rats received drinking water ad libitum containing 300 mg/l CdCl2 throughout the whole lactation. Control animals received a similar volume of water without cadmium. Lactent rats (21 day-old) were killed by lethal dose of... |

| 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... |

| The objective of this study was to analyze the effects of passive smoking, in soleus and gastrocnemius muscles associated with physical exercise by swimming during pregnancy and lactation of rats. Twenty-four rats were divided: GF (exposed to cigarette smoke), GC (control), GFN (underwent to the swimming program and exposed to cigarette smoke) and GN (underwent to the swimming program). On the first day of pregnancy procedure of exposure to cigarette smoke began, consisting in 30 minutes twice a day for six weeks. During the same period the swimming program began, which lasted 60 min every day untilthe 21st day of lactation. Soleus and gastrocnemius muscles, were obtained for histological, histochemical, morphometric analysis and fiber profiling. In... |

| The present work studied the adverse effects of maternal exposure of rats to alcohol during lactation, on the development of their offspring. Histometric evaluation by karyometry and of the palatine epithelium of the sucking was performed. Two groups of animals, one coming from mothers exposed to drinking water containing 20% ethanol during the total lactation period and the other of controls coming from mothers receiving only alcohol-free drinking water during this period. On the 21 first day of lactation the young of each group were aleatorily selected and following anesthesia, their heads severed; after histological treatment, serial 6 |J,m sections on the frontal plane at the molar level, stained with hematoxilin and eosin, were obtained. The... |

| The purpose of this study was to evaluate the effects of zinc, during lactation, on the junctional epithelium and inserted gum of the first upper molar of rats. The study used one-day old male rats, divided into two groups: those whose mother had been treated with 300 mg zinc chloride (ZnCl2) in the drinker water (treated group), and those whose mothers did not receive ZnCl2 (control group). After 21 days, the rat pups were sacrificed. Using karyometrical techniques, the greater (D) and smaller (d) nuclear diameters of the different layers of the junctional and inserted gum epithelia were determined, and the mean geometric diameter, D/d ratio, perimeter, area, volume, volume/area ratio, eccentricity, shape coefficient, and the contour index were estimated.... |
