ABSTRACT
Present authors had recently demonstrated a highly significant double logarithmic linear relationship between time since death and serum sodium/potassium concentration ratio and also with the serum chloride concentration in humans. Consecutively the present study was carried out to substantiate this disposition in vitreous humour. The data on postmortem vitreous sodium/potassium electrolytes concentration ratio in 1026 subjects, revealed a highly significant relationship between logarithm of vitreous sodium/potassium electrolytes concentration ratio and logarithm of time since death upto 66 hrs. of death. Postmortem interval can be predicted from vitreous sodium/potassium electrolytes concentration ratio with standard error of estimate 0.1800 hrs. However, factors like environmental temperature, age & gender also influences it significantly.

Mean organ weights in 2025 subjects who died and autopsied at Postgraduate Institute of Medical Education and Research, Chandigarh revealed that they in general were heavier than reported from other parts of India. Various organs continued to attain their maximum weight up to 40-50 years of age.

Lie detection techniques are utilized by investigating agencies in a wide variety of fields, such as Defence, Secret Services, Terrorism, as the veracity of statements cannot be taken at face value.
