Structural changes in ocular trauma and the visual outcome.

This is the presentation of one year prospective study on the anatomical structural lesions in ocular traumas with their visual outcome among those cases admitted and treated at Nepal Eye Hospital, Kathmandu. The changing life style of the people and environmental changes around with the changing nature of the causative objects on eye injuries have been observed for causing more serious structural lesions or complications including loss of vision.

A study on 'Vermiform Appendix'--a caecal appendage in common laboratory mammals.

The vermiform appendix, a small structure without any known function in human being has been regarded as a vestigial remnant of a more developed distal caecum in man's herbivorous ancestors. A detailed study of the morphological and histological changes in the appendix and the caecum of different mammals with varying dietary habits revealed a distinctly well-defined vermiform appendix in rabbit only. However, the apical part of caecum among the carnivorous animals like cat and dog showed a clear histological picture with heavy infiltration of lymphoid tissue in the mucous & sub-mucous coats as seen in rabbit or human being. Thus, the vermiform appendix is in no way a vestigial organ but a specialized structure without any definitely known function, probably concerned with the establishment and maintenance of the body defence and immunity of the body.
