Renal artery resistance index, thyroid hormones, and thyroid volume in the early kidney transplants recipients.
BACKGROUND: Thyroid hormones could affect renal function, and, on the other hand, renal dysfunction may affect thyroid function. Disturbances of concentrations of thyroid hormones are often associated with thyroid gland enlargement. The aim of the study was to assess the function and morphology of the thyroid (volume and hormones concentration) and kidney function after transplantation (creatinine concentration and resistance index [RI] of transplant artery). MATERIAL AND METHODS: The group included 13 females, 19 males; aged 19-69 years, mean 44.75 +/- 14.8 years after transplantation with stable graft function. Thyroid volume, renal artery RI, creatinine concentration, and concentrations of T3, rT3, FT3, FT4, and TSH were estimated the day before surgery, and at 1, 3, 6, and 10 days after transplantation. RESULTS: The statistical analysis revealed a negative correlation between delta RI (difference between RI at 3 and 6 days after transplantation) and serum creatinine concentration, 10 days after transplantation (r = -0.63; P < 0.01). We also observed a negative correlation between creatinine serum concentration at 10 days after transplantation and delta thyroid volume (Delta Vol; r = - 0.48; p < .05), a positive correlation between delta FT4 (Delta FT4) serum concentration, and delta creatinine (Delta Crea; r = 0.73; P < .001). CONCLUSIONS: The dynamics of RI changes in the transplant kidney artery between 3 and 6 days after transplantation may predict graft function. Together with improved kidney function at 10 days after transplantation, we observed a regression of goiter.

Activity and localization of cathepsin B, D and G in aortic aneurysm.
The activities of cathepsin B, D and G, and their distribution in the walls of normal aorta and those of aneurysms of abdominal aorta were studied. The immunohistochemical reaction for these cathepsins was positive in the aneurysm wall both in the cells and in the extracellular matrix. It was more apparent than in normal aortas. The activities of cathepsin B, D and G in aneurysm were 1.5 times higher than in normal aortas. It may be suspected that besides the action of collagenases and elastases the cathepsins participate in an enhanced degradation of collagen and elastin fibers of aneurysm wall.
