BACKGROUND In patients with limited disease staged small-cell lung cancer (SCLC), overall survival is still poor. Therefore, a retrospective study was carried out of 48 patients with limited disease staged SCLC to select a parameter which can identify prognostic subgroups at the time of diagnosis. MATERIALS AND METHODS Follow-up varied from 3 to 96 months during which 38 patients died. Based ...

The influence of single oral dose of anti-inflammatory, antipyretic and analgesic agents on urinary enzymes was investigated in rats as a indicator of nephrotoxic effect. Urinary LDH activity was significantly elevated by aspirin, ketophenylbutazone, aminopyrine, phenacetin and acetaminophen. These drugs increased also H/M ratio of LDH isoenzymes. Although other test drugs have no effect on LDH...

Four pyridine nucleotide-linked dehydrogenases, glucose-6phosphate dehydrogenase (G6PDH),3 isocitric dehydrogenase (ICDH), lactic dehydrogenase (LDH), and malic dehydrogenase (MDH), and their isozymes have been studied in the normal virgin rat breast, in the breast of tumor-bearing rats, in the breast cancers themselves, and in these tissues following ovariectomy. Enzyme activity expressed per ...

INTRODUCTION LDH-A, the enzyme responsible for transforming pyruvate into lactate, has been demonstrated to be up-regulated in many types of cancer and to give rise to more aggressive behavior by regulating proliferation and anti-apoptosis. However, its expression in gastric cancer (GC) has not been characterized thoroughly. The purpose of this study was to clarify the expression and potential ...

Background: To determine relationship between the levels of serum Lactate Dehydrogenase (LDH)on admission and prognosis of dengue fever. Methods: Patients (n=62) admitted with the diagnosis of dengue fever were included. On admission, serum LDH levels were measured in all patients and to find relationship we monitored all patients upto discharge. Monitoring was done for vitals, different blood ...

Abstract: Risk stratification of Coronavirus disease 2019 (COVID-19) patients is very important to determine patient care and prognosis. The reliable parameters include C-reactive protein (CRP), lactate dehydrogenase (LDH), neutrophil-lymphocyte ratio (NLR). This study aimed the relationship between CRP, LDH, NLR levels with severity COVID-19 patients. An observational a cross-sectional approac...

Platelets (Plt) accumulate in reperfused myocardium but their effect on myocardial necrosis has not been established. We tested the hypothesis that the effect of Plt depends on their activation status. Pig Plt were obtained before 48 min of coronary occlusion (pre-CO-Plt), 10 min after reperfusion (R-Plt), or after a 60-min sham operation (sham-Plt). Plt were infused into isolated rat hearts (n...

PURPOSE To investigate the relationship between lactate dehydrogenase A (LDH-A) expression, lactate concentration, cell metabolism, and metastases in murine 4T1 breast tumors. EXPERIMENTAL DESIGN Inhibition of LDH-A expression and protein levels were achieved in a metastatic breast cancer cell line (4T1) using short hairpin RNA (shRNA) technology. The relationship between tumor LDH-A protein ...

We prospectively evaluated 150 consecutive patients with Pneumocystis carinii pneumonia (PCP) as their sole initial manifestation of AIDS (group 1). Admission laboratory and radiographic criteria were analyzed for diagnostic and prognostic indicators and compared with those of patients presenting with non-PCP pulmonary manifestations of AIDS (group 2). Mean admission serum LDH level was 465 +/-...

The pathogenesis of Epstein-Barr virus-positive (EBV+) mature T-cell and natural killer (NK)-cell neoplasms is challenging to understand. The clinical features are diverse, with no typical manifestation. Therefore, it is important to analyze the association of the clinical characteristics and prognoses of patients with various factors associated with EBV+ T/NK-cell neoplasms, particularly extra...
