ABSTRACT

A pele representa parte importante do sistema tegumentar, pois desempenha funções como a proteção contra desidratação, lesões e infecções, além de apresentar alto poder de renovação. Histologicamente, a pele consiste de duas camadas funcionais, morfologicamente distintas, a epiderme e a derme. As glândulas mamárias, capsula ungueal e cornos também fazem parte deste sistema. Devido à escassez de dados na literatura sobre o desenvolvimento da pele e dos anexos de natureza córnea em bovinos, o objetivo deste trabalho foi descrever as características morfológicas do desenvolvimento do sistema tegumentar durante os períodos embrionário e fetal em bovinos. Os indivíduos foram divididos em três grupos: Grupo I -embriões de 20-26 dias (n=4); Grupo II -embriões 30-47 dias (n=6) e Grupo III -fetos de 74-140 dias (n=6). Durante o desenvolvimento da pele observou-se diferentes padrões morfológicos de acordo com as regiões analisadas, apresentando índice maior de diferenciação no intervalo entre 30-47 dias de gestação. O aparelho ungueal e a glândula mamária se desenvolvem mais tardiamente entre os dias 74-140 da gestação. Em resumo, estes resultados acerca do desenvolvimento do sistema tegumentar em bovinos, poderão auxiliar na interpretação e compreensão da formação dos órgãos que o constituem, assim como para a compreensão de alterações patológicas associadas à organogênese.


The skin is an important part of the integumentary system, which has important functions such as protection against dehydration, injury and infection, as well as present high potential of renewal. Histologically, the skin consists of two functional layers, that are morphologically distinct, the epidermis and dermis. The mammary glands, ungueal capsule and horn are also part of this system. Due the poor data available on literature about the development of skin and other cornea attachments in bovine, the aim of this study was to describe the morphological characteristics of the integumentary system development during the embryonic and fetal periods in bovine. Individuals were allocated in three groups: Group I -embryos from 20 to 26 days (n=4), Group II -embryos from 30 to 47 days (n=6) and Group III -fetuses from 74 to 140 days (n=6). During the development of the skin it was observed different morphological patterns according to the analyzed regions. Especially, a higher level of differentiation was observed during 30-47 days of gestation. The bovine claw and mammary gland develop later between 74 to 140 days of gestation. In summary, these results related to the development of the integumentary system in bovine may help the analysis and understanding of the development of their organs, as well as the pathological disorders associated to the organogenesis.

ABSTRACT

Among the body tissues nails are known to resist decomposition and disintegration. As such the study undertaken on the nails pattern and growth are presented. The idea came from the ink mark applied during the election voting. In 153 cases the growth rate in different fingers was recorded and statistically analyzed. The results are tabulated. It is possible that identity of the person can be established by growth pattern, unusual marks and history of trimming the nails etc. During the study it was observed that cutting of the nails encourages the growth. If allowed to grow the growth is retarded proportionately. Study was done from March 2000 to June 2000.

ABSTRACT

En el tratamiento de la onimicosis, el crecimiento ungueal es importante para la respuesta clínica del paciente. Se realizó un estudio prospectivo en 15 pacientes con diagnóstico clínico y micológico de onicomicosis a los que se administro fluconazol por vía oral en dosis de 150 mg. tres veces por semana durante tres meses. Se les practicó mensualmente controles médicos y de laboratorio, y se les midió la velocidad y aceleración del crecimiento ungueal en los tres meses durante el tratamiento. En este estudio, la velocidad y la aceleración del crecimiento ungueal mostraron un incremento, durante y al final del tratamiento, en comparación a los meses previos al tratamiento
