The aim of the study was to investigate the relationship between serum EPO, serum creatinine and hematologic parameters. Complete restoration of hemoglobin and hematocrit levels was obtained in 99 patients (70.7%), moderate degree of anaemia with average hemoglobin level 114.7 +/- 12.3 g/l was seen in 37 patients (26.4%) and four patients (2.9%) had posttransplant erythrocytosis. Normal hemoglobin values are generally restored during 3 months after successful renal transplantation. Statistical analysis confirmed significant correlation (p < 0.001) between graft function and hematologic parameters, but none correlation was found neither between serum EPO levels and serum creatinine and not between serum EPO levels and hemoglobin/hematocrit values. Plasma creatinine is not reliable indicator of renal EPO secretory capacity. The degree of correction of anemia is limited by the stage of graft function and correlates with the serum creatinine concentration.

The possibility of modulating DR by successful combined kidney and pancreas transplantation thus holds an attractive promise for the ophthalmologist. From June 1983 until April 1997, a total of 86 combined kidney and pancreas transplantation procedures were performed at the Prague-based Institute for Clinical and Experimental Medicine. All recipients are on close follow-up in terms of their ophthalmic status. However, evaluation of the effect of transplantation is problematic because of the advanced status of DR prior to the procedure. We divided the transplant recipients into two groups according to type of transplantation. In Group I (segmental transplantation), proliferative DR was present in 100% eyes, 70% had undergone vitrectomy, and there were 21% of blind eyes. All eyes had been treated by laser. In this group, long-term stabilization of the finding was observed in three patients. In Group II (whole pancreas transplantation), proliferative and non-proliferative DR was diagnosed in 86% and 14%, respectively. There were 12% of blind eyes, and 70% had been treated by laser prior to transplantation. After a successful transplantation, stabilization was found in 60%, improvement in 18%, and deterioration in 22% of eyes in this group. The stabilization and improvement can be explained by subsequent normoglycemia (HbAlc 5.6%). By contrast, we were unable to provide a satisfactory explanation for the deterioration and progression of these findings.

Its cell morphology is established and maintained at least in part by the cell wall, a rigid but dynamic structure that affords mechanical protection. Although fungal cell walls represent an unique phenomenon, recent progress in research has shown striking parallels between yeast and mammalian cells in the area of cell morphogenesis and proliferation. Further studies promise to shed common light on the processes of cell morphogenesis including the intersections with proliferation control. This review focuses on the recent progress in this promising area in the yeast Saccharomyces cerevisiae. The process of cell wall synthesis in Saccharomyces cerevisiae was reviewed by several authors recently. Briefly, the cell wall represents a complex structure of cross-linked chitin, beta-(1,6)-d-glucan, beta-(1,3)-D-glucan and mannoproteins. Chitin and beta-(1,3)-D-glucan are synthesized by enzymatic complexes at the cell membrane and extruded into the periplasmic space, mannoproteins are synthesized along the yeast secretory pathway, and the site of beta-(1,6)-D-glucan synthesis is still unknown. The principal motif which interconnects individual cell wall constituents was recently identified by Kollár et al. The mechanisms of cross-linking of the polymers in the wall remain unknown, however. Recently, nevertheless, substantial progress has been achieved in understanding the signalling pathways which target the cell wall construction.</p>","PeriodicalId":75423,"journal":{"name":"Acta Universitatis Palackianae Olomucensis Facultatis Medicae","volume":"141 ","pages":"7-16"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20601267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To make HRV analysis more practical, we evaluated prospectively prognostic role of short-term HRV in comparison with other risk stratifiers. Study population consisted of 48 patients with acute MI (mean age 59.6 +/- 10.6 years, 38 males), who were off betablockers. All patients underwent 30-minute ECG recording at supine rest on day 2 and 5 after admission, between 9 and 11 a.m. One ECG channel from a commercial bedside monitor was A/D converted, and subsequently analysed using a purpose-built interactive software. Short-term HRV was computed as the standard deviation of all normal-to-normal RR intervals (SDNN) as well as the square root of the mean of the sum of the squares of differences between adjacent normal RR intervals (rMSSD). Left ventricular ejection fraction (LVEF, in %) was determined using 2D-echocardiography. During one-year follow up, 5 patients (10.4%) died of sudden cardiac death (SCD) and one of non-cardiac death. Subjects who died of SCD presented with significantly lower SDNN parameter on day 5 (28.8 +/- 4.3 vs 39 +/- 18.4, p < 0.006) and similar trend was revealed for rMSSD (12.22.8 vs 24.321, N.S.). Similarly, LVEF was significantly decreased in these patients (35.4 +/- 5.5 vs 49.7 +/- 11.3, p < 0.007). Positive predictive accuracy for prediction of SCD was 17% for rMSSD, 20% for SDNN, 29% for LVEF, and 40% for combination of depressed SDNN (< or = 33 ms) and LVEF (< or = 40). In conclusion, depressed HRV computed from short-term predischarge ECG recordings obtained under standardised conditions is associated with an increased risk of SCD. Such predictive power is substantially increased in combination with depressed LVEF, and this approach seems to be effective as a simple screening method to identify high risk subjects.</p>","PeriodicalId":75423,"journal":{"name":"Acta Universitatis Palackianae Olomucensis Facultatis Medicae","volume":"141 ","pages":"69-73"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20601712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
