Effects of distraction. Histology of epiphyseal plates in rabbit tibia.

Effects of distraction on histology of epiphyseal plates of tibia in 30 Rabbits were studied by applying traction in long axis of right tibia. Animals were divided into three equal groups. Experimental, Sham operated and control group. Proximal and distal epiphyseal plates were prepared for histological study. On comparison of thicknesses of epiphyseal plates of all the groups no statistically significant difference was noted. Histological morphology was also similar in all the groups

Obsessive compulsive neurosis [contemporary concepts]

Obsessive compulsive neurosis is a troublesome but a rare disease, with a prevalence of less than 5 percent of all psychiatric disorders. The scientific concepts on the subject are the outcome of the long continued hard work of many benefactors condensed in the historical background. Glossary of mental disorders and guide to their classification, published by the world Health Organisation, settles many disputes and provides a sound footing for the re-evaluation of previous claims -and for the guidance of future studies. The clinical features, natural history, family studies and personal influences have been tabulated in sequence of the classical history taking, Aetiological factors include only the accepted views, while diagnosis portion includes all the conditions which may present with obsessional symptoms. Current views on complications and various forms of treatment have been summarised, followed by the general prognostic factors
