131I-induced changes in rat thyroid gland function BJMBR
Torlak,V.; Zemunik,T.; Modun,D.; Capkun,V.; Pesutic-Pisac,V.; Markotic,A.; Pavela-Vrancic,M.; Stanicic,A..
Therapeutic doses of 131I administered to thyrotoxic patients may cause thyroid failure. The present study used a rat model to determine thyroid function after the administration of different doses of 131I (64-277 µCi). Thirty male Fisher rats in the experimental group and 30 in the control group (untreated) were followed for 6 months. The animals were 4 months old at the beginning of the experiment and were sacrificed at an age of 9 months. Hormone concentration was determined before 131I administration (4-month-old animals) and three times following 131I administration, when the animals were 7, 8, and 9 months old. The thyroid glands were removed and weighed, their volume was determined and histopathological examination was performed at the end of the...

Effect of hyperbaric oxygenation on the regeneration of the liver after partial hepatectomy in rats BJMBR
Kurir,T.T.; Markotic,A.; Katalinic,V.; Bozanic,D.; Cikes,V.; Zemunik,T.; Modun,D.; Rincic,J.; Boraska,V.; Bota,B.; Salamunic,I.; Radic,S..
The aim of the present study was to assess the influence of hyperbaric oxygenation (HBO) on rat liver regeneration before and after partial hepatectomy. Rats were sacrificed 54 h after 15% hepatectomy, liver and body weights were measured, and serum alanine transaminase (ALT) and aspartate transaminase (AST) activity and albumin levels were determined. The lipid peroxide level, as indicated by malondialdehyde production in the remnant liver was measured, and liver sections were analyzed by light microscopy. Five groups of 10 rats in each group were studied. The preHBO and pre-hyperbaric pressure (preHB) groups were treated before partial hepatectomy with 100% O2 and 21% O2, respectively, at 202,650 pascals, daily for 3 days (45 min/day). The control group...
