Megjegyzések:	The present study evaluates the impact of hypoxia related carbonic anhydrase IX and XII isoenzyme expression as a basic adaptive mechanism to neutralize intracellular acidosis in classical Hodgkin's lymphoma (cHL). METHODS: 81 primary biopsies and 15 relapsed tissue samples diagnosed with cHL were analyzed for necrosis, CAIX and CAXII expression and cell proliferation to compare hypoxia related histological and functional data with survival characteristics. RESULTS: Variable, but highly selective cell membrane CAIX expression could be demonstrated in Hodgkin-Reed-Sternberg (HRS) cells in 39/81 samples (48.1%) while virtually no staining presented in their microenvironment. In contrast, CAXII expression in HRS-cells could be demonstrated in only 18/77 samples (23.4%) with significant stromal positivity (50/77, 64.9%). The CAIX+ phenotype was strongly associated with lymphocyte depletion (4/4, 100%) and nodular sclerosis (29/51, 56.9%) subtypes. CAIX/Ki-67 dual immunohistochemistry demonstrated suppressed cell proliferation in CAIX+ compared to CAIX- HRS-cells (p<0.001). 72 months progression free survival (PFS) was significantly lower for the CAIX+ group (0.192) compared with the CAIX- group (0.771)(p<0.001) while the overall survival (OS) did not differ (p=0.097). CONCLUSION: Hypoxic stress related adaptation - highlighted by CAIX expression - results in cellular quiescence in HRS-cells potentially contributing to the short term failure of the standard chemotherapy in cHL.

Cím:	Evaluation of the corneal endothelium in patients with diabetes mellitus type I and II / Módis L. Jr., Szalai E., Kertész K., Kemény-Beke A., Kettesy B., Berta A.

Megjegyzések:	The aim of the present study is to determine corneal physiology and endothelial morphology after proper image analysis technique in type I and II diabetic patients. The HbA1c level and the grade of retinopathy were also recorded and correlated with the endothelial parameters. METHODS: 41 eyes of 21 patients with type I and 59 eyes of 30 patients with type II diabetes mellitus (mean age was 40.97 ± 15.46 and 64.36 ± 10.47 years) were examined and compared to age-matched controls. Endothelial cell density (ECD), mean cell area, coefficient of variation of cell area, central corneal thickness, intraocular pressure, and grade of retinopathy were recorded. RESULTS: There was a statistically significant decreased endothelial cell density in type I disease (2428 ± 219 cell/mm2) in comparison with healthy subjects (2495 ± 191 cell/mm2, P=0.02). The diabetic corneas were thicker than normal (P=0.001). The HbA1c level was inversely correlated with the ECD (r=-0.60; P<0.0001) and correlated with the mean endothelial cell area (r=0.60, P<0.0001). Significant correlation was observed between the endothelial morphology and grade of diabetic retinopathy (r=-0.40, ECD; r=0.38, mean cell area; P=0.01 for both). In type II diabetes mellitus no significant difference was found in the evaluated values. CONCLUSIONS: The present study disclosed the alteration of the corneal endothelial morphology in type I diabetes mellitus as compared to normal subjects. The results indicated that type I diabetic corneas are more susceptible to environmental changes than type II corneas.
