Abstract

Saliva is a biological evidence for forensic sciences. Obtaining saliva and performing DNA analysis is an important evidence for sexual assaultcases. In this study, the presence of salivary alphaamyla seenzyme activity in 100 volunteers was examined by SERATEC® Amylase Testcard test method to deter minewhet her human saliva was contamined with human skin. 3 circles with a diameter of 3 centimeters were drawn on the forearms of thevolunteers.Volunteers were askedtokis seach of the secircles by spreading saliva for 5 seconds. Eachcircledrawn on the fore arm was sampled at 0, 3, 6th hour swith swap bar. Samples were diluted in eppendorf tubes with buffer solution of 1 ml card test kit for 1 hour.The volunteers were questione dand recorded for the parameters that mayaffect salivary alphaamyla seenzyme activity.It was found to be negative in 3 cases at 0thhours, 5 cases at 3th hours and 10 cases at 6th hours.As a result, the presence of human alphaamyla seactivity was found to be positive in the are a where saliva was transmitted by kissing in 90% of the case seven at the 6th hour. The presence of salivaryamylase activity was not associated with other parameters. It has beenshown that human alphaamyla secard test can be used in practical life duetoi tsrapidandeasy application and not being affected by the parameters affecting saliva alpha amylase.

Özet

Tükürük, adli bilimler açısından biyolojik bir delildir. Cinsel saldırı olaylarında da tükrüğün elde edilmesi ve DNA analizinin yapılması önemli bir delildir. Bu çalışmada, insan derisine, insan tükürüğünün bulaşmış olup olmadığını tespit etmek amacıylaSERATEC® AmylaseTestkart test yöntemiyle 100 gönüllü üzerinde tükürük alfa amilaz enzim aktivitesinin varlığına bakılmıştır. Gönüllülerin ön kollarına 3 adet 3 santimetre çaplı daire çizilmiştir. Bu dairelerin her birine 5’er saniye tükürük bulaştırarak öpmeleri istenmiştir. Ön kola çizilen her bir daireden farklı saatte olmak üzere 0-3-6. saatlerde swap çubuğu ile örnek alınmıştır. Alınan örnekler eppendorf tüplerinde 1 ml kart test kitinin buffer solusyonu ile 1 saat dilüe edilmiştir. Dilüe edilen örneklerden pipet yardımıyla bir miktar alınıp 3 damla kart testin ilgili bölmesine damlatılmıştır. 10 dakika içinde çıkan sonuçlar kaydedilmiştir. Gönüllülerden tükürük alfa amilaz enzim aktivitesini etkileyebilecek parametreler sorgulanıp kaydedilmiştir. 0.saatte 3 olguda, 3. saatte 5 olguda, 6. saatte 10 olguda negatif saptanmıştır.Sonuç olarak 6. saatte bile olguların %90’ında öpme ile tükürük bulaşan bölgede insan alfa amilaz aktivitesi varlığı pozitif saptanmıştır. Tükürük amilaz aktivitesi varlığının diğer parametreler ile ilişkisinin olmadığı görülmüştür. İnsan alfa amilaz kart testin hızlı ve kolay uygulanması, tükürük alfa amilazını etkileyen parametrelerden etkilenmemesi nedeniyle pratik hayatta kullanılabileceği gösterilmiştir.
