A.; Salihoglu, Y. S.; Aktoz, M.; Dirlik, B.; Altun, A.Aim: This clinical study was planned to assess pulmonary microvascular permeability in patients with Syndrome X (SX) by using a functional imaging tool, technetium-99m-diethyltriaminepentaaceticacid (Tc-99m-DTPA) lung clearance scintigraphy, and the pulmonary functions test, which includes diffusion capacity of the lung for carbon monoxide (DLCO). Methods: The study population consisted of 22 non-smoker subjects divided into two groups. First group comprised 12 patients (4 male, 8 female, mean age: 48 +/- 4 years, range 36 to 65) with SX. Ten healthy subject (4 men, 6 female, mean age: 45 +/- 3 years, range 34 to 58) were served as control group. Volumetric pulmonary functions, including DLCO were also performed before lung scintigraphy. Alveolar epithelial permeability was assessed by measuring the pulmonary clearance of an inhaled Tc-99m-DTPA using a gamma camera. Results: Spirometric data was comparable in both groups. Although volumetric pulmonary measurements were similar, DLCO values of SX patients were lower than those in control (20.9 +/- 1.7 ml/min/mmHg vs. 27.8 +/- 1.3 ml/min/mmHg, p=0.002). The mean clearance rate of Tc-99m-DTPA in control subjects was 106 +/- 6 min, and this value was lower than patients with SX (179 +/- 19 min; p=0.0001). Conclusion: We conclude that lung is a target organ for SX. The pulmonary gas exchange and microvascular permeability, which is measured by 99mTc-DTPA scintigraphy, are restricted without change of volumetric pulmonary functions in patients with SX. Hippokratia 2012; 16 (2): 113-117Öğe Quantitative analysis of salivary gland scintigraphy in tobacco smoker(Springer, 2005) Sen, S.; Durmus-Altun, G.; Bedel, D.[Abstract Not Available]Öğe Radioiodine-induced kidney damage and protective effect of amifostine: An experimental study(Lithographia, 2012) Aktoz, T.; Durmus-Altun, G.; Usta, U.; Torun, N.; Ergulen, A.; Atakan, I. H.Background: Ablative radioiodine-131 (I-131) therapy is used in the standart treatment procedure of thyroid carcinoma and procedures using I-131 represent the majority of Nuclear Medicine therapeutic procedures. The principal route of I-131 excretion after the administration of I-131 is the urine. Amifostine is an organic thiophosphate ester prodrug and the kidney concentrations of the active metabolite WR-1065 are about 100 times higher than tumour concentrations. To our knowledge, there is no published data in literature presenting acute effect of radioiodine on renal tissue during high dose I-131 radioiodine treatment (RIT). Additionally, it is not known whether amifostine takes role in this process. Materials and methods: In this study, 50 healthy female Wistar albino rats, weighing 200-250 g and averaging 16 weeks old were utilised. The rats were randomly divided into ten groups. 1-Sham group (n=5), 2-Amifostine group (n=5): rats pretreated with 1 cc amifostine (200 mg/kg) by intraperitoneal injection, 3- Radioactive iodine first day group (RI-1) (n=5): rats treated with 1 cc oral 185 MBq radioactive iodine-131 and sacrification performed after 1st day, 4- Amifostine + Radioactive iodine first day group (A+RI-1) (n=5): rats pretreated with amifostine (200 mg/kg) by intraperitoneal injection and rats treated with 5mCi radioactive iodine-131 and sacrification performed after 1st day. 5- Radioactive iodine third day group (RI-3) (n=5), 6- Amifostine + Radioactive iodine third day group (A+RI-3) (n=5), 7- Radioactive iodine fifth day group (RI-5) (n=5), 8- Amifostine + Radioactive iodine fifth day group (A+RI-5) (n=5), 9- Radioactive iodine seventh day group (RI-7) (n=5) and 10- Amifostine + Radioactive iodine seventh day group (A+RI-7) (n=5). The renal cast formation and tubular damage are evaluated by a pathologist in a blinded manner. Results: Ablative radioiodine-131 therapy induced renal tubular damage was significantly higher in the radioactive iodine fifth day group (RI-5) when compared with the Sham group (p=0.01) and Amifostine group (p=0.01). Conclusions: A marked ablative radioiodine-131 induced renal toxicity was seen at fifth day of the therapy after a single RIT application and the main histopathological change was tubular damage. Amifostine have protective effects against ablative radioiodine-131 therapy and this effect is significant at fifth day of the therapy.
