| ABSTRACT In view of the traditional use of Tabebuia aurea for treating pain and inflammation, the antinociceptive pharmacological potential of T. aurea ethanolic extracts (TAEE) was investigated through in vivo experimental models. First, the MTT assay was conducted to determine the potential cytotoxicity of the TAEEs. Afterwards, the acetic acid-induced writhing test and the formalin-, and glutamate-induced nociception tests were performed on Swiss adult mice treated with TAEEs (100 and 200 mg/kg doses, p.o.), or saline solution (control groups, 10mL/kg, p.o.), or standard drugs: dipyrone 40 mg/kg (p.o.), and morphine 5,7 mg/kg (i.p). In the MTT assay, none of the tested concentrations demonstrated signals of cytotoxicity. In the in vivo experimental... |

| The effect of a compound combining Valeriana officinalis and Passiflora alata extracts was tested on two mouse memory models: habituation and step-through inhibitory avoidance. Diazepam (1.0 and 2.5 mg/kg) was used as a positive control. Acute diazepam (2.5 mg/kg) before training impaired the habituation and performance in the inhibitory avoidance. On the other hand, acute phytotherapeutic compound (40-160 mg/kg), also before the training session, did not alter mouse behavior in these models. Repeated (15 days) treatment with the compound also did not impair the habituation. At the doses used, no locomotor effect was found. Taken together, the results suggest that, contrary to diazepam, the anxiolytic Valeriana officinalis and Passiflora alata compound did... |

| Rhododendron honey, made by bees from rhododendron pollen, contains a toxic substance called grayanotoxin. Depending on the dose, the poisonous honey can result in serious effects such as cardiac arrhythmia, fibrillation, and myocardial infarction. The purpose of this study is to investigate the effects of the poisonous RH of the Black Sea Region on the liver. Male mice were divided into five groups of twelve mice each, two being the control groups (distilled water) and the others being the rhododendron honey (RH) groups (25, 50, and 75 mg/kg) and 0.01 mg/kg grayanotoxin (GTx) groups. Liver tissues were collected 24 and 48 h later. The sections were stained with hematoxylin, eosin and PAS, then the histopathological score was performed. Significant... |

| Vasectomy is a common contraceptive procedure in men. The present study is aimed to explore the impact of vasectomy on epididymal morphology and sperm parameters in adult male Balb/c mice. Twenty adult (age: 8 weeks) male Balb/c mice, weighting 20-30 g were used in the experiments. They were divided into 2 groups (vasectomy and sham). The operations were performed under sodium pentobarbital (40 mg/kg body weight, IP) anesthesia via a lower mid-abdominal incision. The left epididymis caput was fixed for histological studies and the right one was used for sperm count and motility. Progressive fast and slow sperm motility were significantly decreased in the vasectomized compared to the sham operation group (P<0.05) and the number of immotile sperm in the... |

| The present work aimed to verify the effects of Baypamun®HK on the survival of albinic mice, experimentally infected with Toxoplasma gondii RH strain, treated or not with sulfadiazine-pirimetamine, as well as on the formation and the number of brain cysts. Four groups of 20 mices were inoculated with 10(5) tachizoites, subcutaneously, and undergone to different treatments. Serum tests were carried out by indirect immunofluorescence and samples of brain, liver and lung were collected from animals who died for cytological and brain cysts examinations. After 60 days, all survivors were sacrificed. Isolated Baypamun®HK didn't present a protective action against the infection by T. gondii, but its association sulfadiazine-pirimetamine, a specific treatment... |

| Acute toxicity test (LD-50) using toxic shock syndrome toxin (TSST-1) was tested in BALB/c, C57BL/6 and Swiss mice. Animals (n = 10) were intraperitoneally injected with TSST-1 (0.01-10.0µg/mouse) followed 4h later by potentiating dose of lipopolysaccharide (75.0µg of LPS - E. coli O111:B4) and cumulative mortality was recorded over 72h. Control animals received either TSST-1 or LPS alone. The data were submitted to qui-Square test and acute toxicity test was calculated by probit analysis (confidence limits expressed as µg toxin/kg). BALB/c mice was the most sensitive (20.0µg/kg, 95% confidence limits: 9.0-92.0) followed by C57BL/6 (38.5µg/kg, 95% confidence limits: 9.11- 401.6). Data from Swiss mice was not conclusive, indicating only low sensitivity.... |

| Mesenchymal stem cells (MSC) are present in specialized niches in perivascular regions of adult tissues and are able to differentiate into various cell types, such as those committed to repairing. Bone marrow derived MSC from eight young mice C57BL/ 6 gfp+ were expanded in culture for repairing critical defects in calvarial bone produced in twenty-four young isogenic adult C57BL/6 mice. The animals were subjected to a cranial defect of 6.0mm diameter and divided into two equal experimental groups. Control group did not receive any treatment and the treated group received a MSC pellet containing 1.0 x 10(7) cells/mL into the defects. The group treated with MSC showed increased angiogenesis and amount of new bone deposited on the defect limits than that... |

| The objective of this study was to describe some changes in spermatids differentiating events during spermiogenesis, leading to spermatozoa final formation. The animals were sacrificed with ethylic acid inhalation and, then, testis fragments were collected, fixed in Karnovsky and post-fixed in osmium tetroxide. After dehydration, the sections were stained with uranyl acetate 2%. It was observed in early spermatids at Golgi phase, formation of acrosomal granule contained in the acrosomal vesicle, spheroidal nucleus with rugous reticulum around it, and Golgi apparatus made up of lamellae and vesicular structures. At cephalic hood phase, the granule suffers flattening and the marginal fossa is formed. In both phases, it was possible to observe the presence of... |

| The neuromuscular junction of the extensor digitorum longus muscle of fingers was analyzed in 21 young (three months) and old (from six to 25 months) mice, from both genders. Morphologic changes were found throughout the mouse life, being more frequent and visible with aging. According with the data described in the literature consulted and the observations taken in this research, it becomes clear that a continuous process of morphological remodeling occurs in all neuromuscular ultrastructural junctions of the extensor digitorum longus muscle of fingers, during the life of the animal. Theses changes are characterized by figures of myelin in the cytoplasm of Schwann cells, pleomorphic and multivesiclar bodies, mitochondrias with morphologically altered... |
