Establishing the identity of the living or the deceased, which is an essence of any crime investigation, is one of the most challenging matters that forensic science has to deal with. Cheiloscopy is one of the newly emerging tools that aid in this. It is the study of the grooves present on the human lips, at the zone of transition of outer skin and inner labial mucosa. The present study was conducted in the Department of Anatomy, Gauhati Medical College, Guwahati, Assam, amongst a group of 145 1st MBBS students comprising of 89 males and 56 females, with an aim to determine the predominant lip print pattern in different lip quadrants and also to find out any similarity in distribution of lip print patterns in different quadrants in males and females. The prints were analysed after dividing the lips into four quadrants: right upper as Quadrant I, left upper as Quadrant II, left lower as Quadrant III, and right lower as Quadrant IV. The patterns were analyzed following the classification of Suzuki and Tsuchihashi. The recorded data were then statistically analysed using Student's T-test. P value < 0.05 is considered as statistically significant. The data obtained in this study hopes to contribute to the knowledge and understanding of the uniqueness and distribution of lip prints and in turn help in certain medico-legal practices.Keywords

Introduction: Human identification by the use of finger prints is infallible, because the ridge arrangement on every finger of every human being is unique and does not alter with growth or age. The present study has been conducted with an aim to determine the most common thumb print pattern in both males and females and whether there is any relation between them. Methods: The study has been conducted in the Department of Anatomy, Gauhati Medical College, Guwahati, amongst a group of 145 1st MBBS students (89 males and 56 females), having different ethnic backgrounds after approval of the Institutional Ethical Committee. Participants were briefed about the purpose of the study and written informed consent was also taken from them. The thumb print of the dominant hand was taken using printer’s blue ink and was transferred on to a white bond A4 paper. The prints thus recorded were studied with a magnifying lens and were classified on the basis of Michael Kucken’s classification system as Loop, Arch, Whorl and Composite pattern. Results: The present study revealed that there is no significant difference between male and female as far as the distribution of the different types of thumb print is concerned. Also, it is seen that the ‘loop’ and ‘whorl’ variety is much higher than the ‘arch’ and ‘composite’ variety of print which is more evident in case of males. Discussion: The finding of our study has the similarity with the observations made by other researchers in this field. Conclusion: Such a study may be useful in establishing a database which may be useful in various medicolegal cases to identify an individual.Keywords

Introduction: At various times in the history of medicine the precise function of the small discrete pea-like structure we have in the centre of our brains, called the pineal gland (“corpus pineale”), was considered to be a memory valve, a valve controlling circulating vital fluids, the seat of the soul, and the site of a presumed pathology causing certain types of mental illness. In the mid nineteen fifties this confusion began to clear when the pineal gland’s true function was discovered. The gland is a neuroendocrine gland and consists of parenchymal cells, called pinealocytes and neuroglial cells. Melatonin, 5methoxy- N-acetyltryptamin, is a neurohormone of the brain produced by pineal gland. The modern systematic study of the pineal gland began in 1954. There are very few literatures where the size of the pineal gland has been described.
Material and Methods: In the present study 50 numbers of MRI cases done for various purposes, where no pathology of brain was detected were taken in the Radiology department of Gauhati Medical College after obtaining due consent. The length (Anteroposterior diameter) and breadth (Cranio-caudaldiameter) of the pineal gland was recorded. The data recorded was analysed statistically using Student’s T-test. P value d” 0.05 is considered as statistically significant.
Result: The maximum mean length of pineal gland was observed asbe 5.715±0.651 mm in the age group of ‘20 to below 40’ years.
Discussion: The findings of our study has the similar [ty with the observations made by other researchers f this field.
Conclusion: Such a study may be useful in establishing a database which may be useful in correlating the size of the gland with various brain pathology.
