| Cadmium (Cd), is an environmental and industrial pollutant that affects the male reproductive system. Cd induces its effect by affecting tissue antioxidant enzyme systems. Green tea extract (GTE) is an antioxidant and free radicals scavenger and has a chelating property. The purpose of this study was to investigate the protective effect of GTE against testes damage induced by Cd. Four groups of male rats, were utilized as following: Controls, GTE treated, Cd treated and Cd + GTE, treated rats at the same doses. The rats received GTE and or Cd orally in drinking water. After 5 weeks, the animals were sacrificed and testes were removed for microscopic and Biochemical evaluation. The levels of lipid peroxides (LPO) and glutathione (GSH) were detected in the... |

| Los trastornos temporomandibulares (TTM) son prevalentes en la población, siendo su etiología multifactorial. Los factores etiológicos pueden agruparse en estructurales, funcionales y psicosociales. Los estudios demuestran que el 75% de la población presentan signos y 33% síntomas de TTM.Los factores estructurales, como las asimetrías de los componentes de la articulación temporomandibular, juegan un rol importante. La asimetría condilar se ha estudiado en diferentes patrones esqueletales. Se evaluaron 331 radiografías panorámicas y telerradiografías de sujetos de edades entre 8 a 18 años. Se evaluó el ángulo ANB y la altura del proceso condilar mediante el método de Habets et al. (1988). De acuerdo a la medición de la ángulo ANB, las clases esqueletales... |

| All organs of the immune system are innervated and almost all neurotransmitter receptors are present on immune cells. We studied the effects of sympathetic innervation in the development of amebic liver abscess (ALA) in rats. Our results showed that lack of sympathetic innervation promote a decrease in size of ALA. We found scarce amoebas, increased the number of neutrophils and a few collagen fibers surrounding the abscess, meanwhile in control group, we observed abscesses areas with typical necrosis including trophozoites and neutrophils. Macrophages were differentially distributed surrounding abscess area in control and vehicle groups, but equally located in and outside of the abscesses in sympathectomized rat. No significant differences were observed... |

| This study provides a detailed description of the arteries supplying the soft palate via: (i) ascending palatine; (ii) tonsillar; (iii) ascending pharyngeal; and (iv) lesser palatine arteries. Detailed dissections were performed on each side of thirty fetal and twenty adult head and neck specimens (n=100). This investigation documents the arteries terminating at the respective parts (superior, middle and inferior) of the soft palate and demonstrated that the majority of arteries terminated at the superior (83%) and middle (63%) parts, whereas the inferior part (34%) was documented to receive the poorest arterial supply. The present study recognized anastomotic connections in 6% of fetal specimens i.e. (i) between the ascending palatine and lesser palatine... |

| Sacrum is formed by the fusion of five sacral vertebrae and forms the lower part of vertebral column. The opening present at the lower end of sacral canal is known as sacral hiatus. Anatomical variations in morphology and morphometry of sacral hiatus are important clinically as well as surgically. 159 dry clean human Sacra were taken from Department of Anatomy, Sri Guru Ram Das Institute of Medical Sciences and Research Vallah (Amritsar). Various shapes of sacral hiatus were observed which included inverted U (42.95%), inverted V (27.51%), irregular (16.10%), dumbbell (11.40%) and bifid (2.01%). The apex of sacral hiatus was commonly found at the level of 4th sacral vertebra in 56.36%. The mean length of sacral hiatus was 22.69 mm. The mean anteroposterior... |

| Knowledge of the varying drainage patterns of superficial veins of head & neck, in particular, jugular veins are not only important for anatomists but also for the surgeons operating at this level and to clinicians in general. The variations are important for interventional radiologists too who perform transjugular procedures, such as port implantations and the transjugular intrahepatic portosystemic shunt or selective venous samplings. Results of recent studies report that the superficial veins, especially the external jugular vein (EJV), is been increasingly utilized for cannulation to conduct diagnostic and therapeutic procedures. We report a very unusual presentation of external jugular vein on left side of an embalmed male cadáver.... |

| This study aimed at answering the question whether production of new colour variants of American mink in mink farms using mutations may entail changes in skull morphology and relationships between the bone elements building it. Analyses were made on the skulls of 56 eight-month-old males and females of two American mink colour variants (standard Brown and mutant Sapphire) from the same farm. Mean values, standard deviations and coefficients of variation were determined for carcass weight, cranial and mandibular weights and 7 dorsal surface, 8 lateral surface and 11 basal surface traits of the skull. The values of 24 cranial and mandibular indices and the values of sexual size dimorphism (SSD), i.e. a coefficient describing differences between sexes, were... |

| A multimedia program has been developed at the Departament of Human Anatomy, Medicine School of Universidad Autónoma de Nuevo León. It offers an alternative to support the traditional laboratory practice and resolve, during the dissection, the most common problems that we have already identify in our students. Some features of this program are: photography's, diagrams, information about the structures, clinical correlation and tests. All this tools were integrated in a software using Macromedia Flash. The final result is a multimedia program that will be used by students during their laboratory practice. At present, we are making a study to determine the effect that is produced in the development of the students in the anatomy lab |

| The jugular foramina (JF) are bilateral openings situated between the lateral part of the occipital bone and the petrous part of the temporal bones in the human skull. It is a bony canal transmitting neurovascular structures from the posterior cranial fossa through the base of the skull to the carotid space. Since the JF depicts variations in shape, size, height and volume between different racial and gender groups, along with distinctive differences in laterality from its intracranial to extracranial openings, knowledge of the JF may be necessary to understand intracranial pathologies. Therefore, the purpose of this study was to evaluate the morphometric measurements of the jugular foramen. Various morphometric parameters of the JF and its relation to... |

| The mandibular condyle is the rounded protuberance that articulates with the mandibular fossa to form the temporomandibular joint (TMJ). The shape of the mandibular condyle may be classified according to five basic shapes viz. flattened, convex, angled, rounded and concave. Previous research indicated that variation in the shape and size of the mandibular condyle, exists and that population-specific differences may also occur. This study aimed to document the shapes and size of the mandibular condyle and determine their relationship with regard to sex, age and race (if any). The morphometric and morphological parameters of the mandibular condyle were measured and assessed in 54 dry mandible specimens (n= 108). The Wedel et al. (1978) classification scheme... |
