Item Anthropometric knee profile measurements on articulator surface of femur among Sri Lankan population.(Sri Lanka Medical Association, 2023) Fernando, G.K.S.; Ranaweera, L.; Cabral, L.L.E.; Dissanayaka, P.; Bandara, I.D.M.R.N.; Sovis, W.F.U.N.INTRODUCTION: In Sri Lankan context there are no published data for articulator surface measurements for knee joints. Forensic, Anatomical, Archaeological, Bio-medical engineering, development of knee S145 prosthesis beneficial with anthropometrics. Digital Vernier Caliper (measuring range 0-140mm, resolution 0.02mm, accuracy ±0.01mm) used to obtain measurements. OBJECTIVES: The aim of this study, was to provide standard anthropometrics for the distal femur in Sri Lankan context. METHODS: Dried adult Femurs (42 male and 28 female) were analysed for the measurements of Medial condyle Antero-Postero Length (MAP), Anteroposterior length of intercondylar area (AP), Medial-Lateral Length (ML), Aspect Ratio (ML/AP) and Epi Condylar breadth (EB). Sex Dimorphism Ratio (SDR) were calculated for dry femurs. RESULTS: The mean values for male; MAP 24.95(±2.22), AP 25.47(±2.27), ML 20.82(±2.56), Aspect Ratio 0.82(±0.11) and EB 7.68(±0.43). The mean values for female; MAP 24.95(±3.08), AP 25.47(±3.16), ML 20.82(±2.28), Aspect Ratio 0.82(±0.18) and EB 7.68(±0.37). SDR values are MAP 107.74, AP 107.12, ML 99.04, and EB 106.55. CONCLUSIONS: The majority of SDR values lie above 100. Therefore, a difference between male and female values can be observed. Findings offer assistance to develop knee joint prostheses with culture-particular values, fitting for the Sri Lankan setting and pave the pathway to the studies on the above-mentioned fields in the local and international context. Sex determination is a crucial element in the creation of a biological profile since it offers information for identities.Item Changes in erythrocyte glucose-6-phosphate dehydrogenase (G6PD) and reduced glutathione (GSH) activities in the development of senile and diabetic cataracts(SEAMEO Regional Tropical Medicine and Public Health Project, 2008) Chandrasena, L.G.; de Silva, L.D.R.; de Silva, K.I.; Dissanayaka, P.; Peiris, H.Oxidative and osmotic stress have been implicated in the pathogenesis of cataracts. Reactive oxygen intermediates (ROI) mediate peroxidation of membrane lipids and cause irreversible damage to lens proteins. The purpose of this study was to assess the changes in erythrocyte glucose- 6-phosphate dehydrogenase enzyme (G6PD) and reduced glutathione (GSH) levels in the development of senile and diabetic cataracts. The activity of erythrocyte G6PD and the concentration of GSH were measured to assess changes in oxidation-reduction status. The oxidation-reduction status of 26 non-diabetic non-cataract (control) subjects were compared with 24 diabetic non-cataract, 30 diabetic cataract and 28 non-diabetic cataract subjects. The results revealed that the GSH and G6PD levels of the subjects with senile cataracts were significantly lower than the subjects without cataracts. The present study reveals the risk of developing senile cataracts is associated with decreased levels of erythrocyte G6PD and GSH. In the formation of diabetic cataracts an adequate supply of NADPH (G6PD activity) is essential to produce osmotically active sorbitol in the lens
