引言在犯罪现场发现的指纹是重要而有价值的证据,因为它们对每个人都是独一无二的。从犯罪现场获得的血液样本中确定血型有助于识别一个人。然而,在没有血迹的地方,在犯罪现场获得的唾液可用于识别受害者。由于指纹模式和血型对每个人都是独一无二的,并且在整个生命中保持不变,皮纹和血型之间的相关性可以用于受害者识别。目的进行本研究的目的是找出指纹模式的分布与血型之间是否存在任何关联,以及这种关联是否可用于性别识别。材料和方法在200名年龄在18至24岁之间的牙科本科生(女性:n=152,男性:n=48)中确定了指纹模式。采用吸收-洗脱法对唾液进行ABO血型鉴定。为了确定使用唾液进行ABO血型测定的准确性,与血液中ABO血型相关.观察和结果发现最常见的指纹模式是环(87,43.50%),其次是螺纹(81,40.50%)和拱门(32,16.00%)。最常见的血型是B(68,34%),其次是O(46,23%)和A(42,21%),最不常见的是AB(12,6%)。女性(130,86%)的唾液分泌物百分比高于男性(38,79%)。性别与血型和指纹图谱的相关性显示,最常见的血型是B(20,42%),最常见的指纹模式是螺纹(21,44%)。在女性中,最常见的血型是B(48,32%),而最常见的指纹模式是loop(68%,45%)。结论本研究报告了血型和皮纹之间的关联,这可能有助于性别识别。在没有血迹的情况下,唾液可以用作受害者识别的有用工具。
Introduction Fingerprints found at the crime scene are important and valuable evidence, as they are unique to every individual. Determining the blood group from the blood samples obtained at the site of the crime helps in identifying a person. However, where blood stains are not available, saliva obtained at the crime site can be used to identify the victim. Since fingerprint patterns and blood groups are unique to every individual and remain unchanged throughout life, the correlation between
dermatoglyphics and blood groups can be of use in victim identification. Objectives The present study is conducted with the objective of finding out if there is any association between the distribution of fingerprint patterns and blood groups and if this association is of use in gender identification. Materials and method Fingerprint patterns were determined in 200 (females: n = 152, males: n = 48) dental undergraduate students in the age range of 18 to 24 years. ABO blood grouping was done on saliva by using the absorption-elution method. To determine the accuracy of ABO blood group determination using saliva, it was correlated with the ABO blood grouping in blood. Observations and result The most common fingerprint pattern was found to be loops (87, 43.50%), followed by whorls (81, 40.50%) and arches (32, 16.00%). The most common blood group was B (68, 34%), followed by O (46, 23%) and A (42, 21%), and the least common was AB (12, 6%). A higher percentage of secretors in saliva was observed in females (130, 86%) than males (38, 79%). The correlation of gender with blood group and fingerprint pattern showed that in males, the most common blood group was B (20, 42%), and the most common fingerprint pattern was whorls (21, 44%). In females, the most common blood group was B (48, 32%), while the most common fingerprint pattern was loop (68, 45%). Conclusion Present study reports an association between blood group and
dermatoglyphics, which may help in gender identification. Saliva can be used as a helpful tool in victim identification in cases where blood stains are not available.
