Serum and Tissue Levels of Vitamin a and E in Gastric and Esophageal Cancer
(1996) Turkdogan, M.K.; Testereci, H.; Kahraman, T.; Tuncer, I.; Algun, E.; Yoruk, I.H.
Vitamin A and Vitamin E have antioxidant properties and their role in the prevention of gastrointestinal cancers by way of scavenging lipid peroxidation products is very important. Vitamin A ester (retinol acetate) and vitamin E isomers (alpha, gamma and total tocopherols) have been investigated in the serum samples and tissue biopsies of 7 esophageal, 12 gastric cancer patients and a control group consisting of 12 healthy subjects. The serum mean retinol acetate level was significantly higher in the gastric cancer group but not in patients with esophageal cancer when compared to the control group. Serum mean tocopherol levels were low in both cancer groups when compared to the control group but this did not reach biological significance. Tissue mean retinol acetate and tocopherol levels were found significantly low in both of the cancer groups (p<0.03 and p<0.08). These findings suggest that the low tissue levels of the antioxidant vitamin A and E may be related to the etiopathogenesis of the gastrointestinal cancers.
True Hermaphroditism Presenting as an Inguinal Hernia
(Brazilian Society of Urology, 2007) Ceylan, K.; Algun, E.; Gunes, M.; Gonulalan, H.
A 21-year-old patient with cryptorchidism was found to have a left inguinal mass on physical examination. The patient was operated with a diagnosis of bilateral cryptorchidism and left inguinal hernia. Besides bilateral inguinal undescended testicles, female genital organs like fallopian tubes, uterus and ovary were found on the exploration.
Value of Fibrinogen as a Marker in Gastrointestinal Cancers
(1997) Turkdogan, M.K.; Akman, N.; Ercan, M.; Tuncer, I.; Algun, E.
Increase of some coagulation factors and tendency to venous thrombosis have been reported in gastrointestinal cancers. In this study, plasma fibrinogen levels have been investigated in 24 patients with gastrointestinal cancer (esophageal, gastric and pancreatic cancer). Significant increase has been found in the esophageal cancer group (p < 0.01). Plasma fibrinogen levels were also elevated in two pancreatic cancer patients (9.52 and 6.45 gr/lt) but they were normal in gastric cancer patients. These results suggest that fibrinogen may be a useful tumor marker in some gastrointestinal cancers and further investigations are required in a large number of patients.
