| Agenesia es la ausencia de dientes por alteraciones genéticas aisladas o sindrómicas. La agenesia del tercer molar está asociada a malformaciones y considerada por diversos autores consecuencia de la evolución humana (Larmour et al., 2005). Son los dientes con mayor prevalencia de agenesia junto a los segundos premolares e incisivos laterales (Fuller & Denehy, 1984). La prevalencia varía entre 9 y 37% (McNamara & Foley, 2006), en tanto, Arboleda et al. (2006) señalan una prevalencia del 20%. La literatura señala variables estadísticas porcentuales, por género, por arcada dentaria, por lado y por diente, con escasos artículos sobre grupos originarios de Chile. La población en estudio consistió en 33 hombres y 57 mujeres de 16 a 55 años, de... |

| The aim of this study is to evaluate the prevalence of agenesis of palmaris longus muscle tendon among school children in Ogun state, Southwestern Nigeria and also, to verify the symmetry of the agenesis of the muscle in relation to sex. The presence of the palmaris longus muscle tendon was determined in 564 individuals, 285 male and 279 female, with age varying from 2 to 20 years old. Four different tests were used; Schaeffer's test, Thompson's test, Mishra's test 1 and Pushpakumar's "two-finger sign" method. The data obtained were further analyzed statistically and the agenesis of palmaris muscle was found to be 26.7% (unilateral 13.0%; bilateral 13.7%). Prevalence was higher in female (32.3%) than male (21.4%) (P>0.05). Besides, we observed higher... |

| ICAM-1 which is expressed by endothelial cells and leukocytes are observed as first markers in diseases such as transplant rejection, diabetes and atherosclerosis and in infections caused by various pathogens. In the present study, it is aimed to reveal the age-related changes in the expression of ICAM-1 on rats. Therefore, a total of 30 albino rats were taken at the age of 6, 18 and 24 months without gender discrimination. Rats were fed with standard pellet feed during the study. Afterwards, rats were sacrificed and tissue samples were collected from their rats, and the samples were evaluated under the light microscope by staining with immnunohistochemical method. It was determined that the expression of both aortic endothelial cells and endothelial cells... |

| Disturbances of the urinary bladder functions are common in the elderly people particularly women. So, it was the aim of the present work to detect the age-associated changes in the urinary bladder that might play a role in the bladder dysfunctions. Twenty albino rats were used in the present work. They were divided into two equal groups, each consisted of ten rats. The first group included the adult rats (aged 3 months) and served as control group, while the second group was the senile rats (aged 24 months). Specimens of the urinary bladder were taken, processed and examined using the light microscope (LM) and the scanning electron microscope (SEM). Light microscopic examination of the urinary bladder of the aged rats showed marked mucosal damage, ranging... |

| Oral pyogenic granuloma is a hyperplastic inflammatory lesion commonly associated to local irritation or trauma. Females are more affected than men probably due to the vascular effects of hormones that occur during puberty, pregnancy and menopause. In the pregnancy, the lesions are known as "pregnancy tumor" and tend to occur more frequently during the second and third trimester. In the oral cavity, histopathological examination is required for diagnosis, since the lesion is clinically indistinguishable from other reactive lesions and, usually, there is no evidence of bone involvement. The authors report a rare case of pyogenic granuloma with destruction of alveolar bone mimicking a malignant tumor in a 20-year-old woman in the 19th week of pregnancy. |

| En este trabajo son descritas alteraciones en la erupción de los caninos permanentes, su etiología, diagnóstico temprano y posibilidades terapéuticas. El canino recoge todos los problemas de espacio que puedan existir en la arcada y es frecuente la erupción en una zona alta. La inclusión de los caninos tiene una etiología compleja, favorecida por factores evolutivos, anatómicos y mecánicos. La impactación mandibular es menos frecuente y su incidencia se describe como veinte veces menos que la impactación del canino maxilar. La erupción ectópica de los caninos maxilares puede estar asociada a la reabsorción de las raíces de los incisivos adyacentes. A la edad de 8 a 10 años empieza a palparse la prominencia del canino en el fondo del vestíbulo. Los métodos... |

| En América Latina la presencia del arsénico en el ambiente y en las fuentes de agua para consumo humano, se debe a factores naturales de origen geológico como a actividades antropogénicas. El arsénico en las aguas naturales se encuentra principalmente como trivalente (arsenito) o pentavalente (arsenato). El objetivo de este trabajo fue determinar las alteraciones que provoca el trióxido de arsénico a nivel de la morfología del bazo de ratas (Rattus norvegicus - Sprague-Dawley). Se utilizaron 24 ratas de ambos sexos de 55 días de vida. Las ratas fueron pesadas y divididas en 3 grupos (4 hembras y 4 machos). Los grupos tratados fueron inyectados con 5 mg y 10 mg de As2O3 respectivamente, en dosis única diaria vía intraperitoneal por 15 días. Al grupo control... |

| Petiveria alliacea, es conocida con diferentes nombres según el lugar donde se le encuentre. Estudios con hojas, tallo, raíz o extractos describen múltiples usos medicinales. Sin embargo, son pocos los que describen efectos tóxicos. En este estudio se evaluó el efecto morfológico de los vapores de la raíz de P. alliacea sobre el tracto respiratorio de ratas Wistar. Se emplearon 15 ratas divididas en 5 grupos (n=3): control absoluto, 0, 5, 15 y 30 minutos post-exposición (grupos I-V, respectivamente). Las ratas se sacrificaron y se colectaron muestras representativas del tracto respiratorio que posteriormente se procesaron por la técnica histológica convencional, hasta su inclusión en bloques de parafina. Los cortes histológicos se tiñeron con H-E,... |
