Organ weights in autopsy cases from an urban apex hospital.

The available limited anatomical and physiological data have been compiled for Indian adult as a part of ongoing efforts in the country to formulate an Indian Reference Man for radiation protection purposes. The parameters included weight, height, body surface area, weight of various organs (brain, heart, kidney, lung, liver etc.), total body water, extra-cellular water, blood volume, specific gravity, total lung capacity, vital capacity etc. The data have been drawn from post-mortem studies (566 males and 185 females) and other data from published work on 433 healthy male and 137 female volunteers. Data gaps have been filled by the method of pooling wherever necessary. This paper presents the intercomparison of the present data with the data available from other sources. The data from various Indian sources indicate a similar trend. However, a significant difference (P less than 0.01) was observed in organ weights and total body weights, in comparison to the Bhabha Atomic Research Centre (BARC) values. The present data are not comprehensive enough to suggest definitive norms of the Indian Reference Man.
