dc.description.abstract50 ÖZET Çağımızın önemli görmezlik nedenlerinden olan kataraktın oluşumunda eser elementlerin rolünü araştırmak amacıyla 48 senil kataraktlı hastanın serumu, bunlardan 42' sinin lensi ve 10' unun hümör aközünde ve kontrollerde çinko, bakır ve selenyum düzeyleri atomik absorpsiyon spektrofotometresi ile ölçülmüştür. Kataraktlı hastaların serum bakır değerleri kontrollere göre yüksek, selenyum değerleri ise düşük bulunmuştur (p<0.05). Kataraktlı hastaların hümör aköz selenyum konsantrasyonları, kontrollere göre düşük bulunmuştur (p< 0.05). Hasta alt grupları da analiz edilmiş ve kortikal kataraktlı hastaların gerek serum, gerekse lens bakır konsantrasyonları, nükleer kataraktlı hastalarınkinden yüksek bulunmuştur (p<0.05). Çalışmamız sonucunda bakırın serum ve lens korteksindeki yüksekliğinin, selenyumun ise serum ve hümör aközdeki düşüklüğünün katarakt gelişim nedenlerinden olabileceği kanısına varılmıştır.
dc.description.abstract51 SUMMARY Zinc, copper and selenium levels in 48 serum, 42 lens and 10 humour aqueous samples of 48 patients with senile (nuclear and cortical) cataract were measured by atomic absorption spectrophotometry and the results compared with corresponding controls, in an attempt to determine the role of trace elements in the pathogenesis of cataract which is an important cause of blindness. Serum copper levels were increased whereas selenium levels were decreased in patients with senile cataract compared to the controls (p<0.05). Humour aqueous selenium levels were decreased in cataractous patients when compared to the controls and this was statistically significant (p<0.05). On the other hand, subgroups of patients were analysed and it was found that both lens and serum copper levels were significantly increased in patients with cortical cataract when compared to those with nuclear cataract (p<0.05). The results obtained suggest that increased levels of copper in sera and lens cortex and decreased levels of selenium in sera and aquous humour may be among the factors leading to the development of senile cataract.en_US
