A 6-kilobase fragment extending at the 5'-end of the c-erbB2 protooncogene was isolated from a normal human lymphocyte genomic DNA library. The full-length fragment and five subfragments with identical 3'-ends were obtained by progressive unidirectional deletion from the 5'-end and were cloned in front of the luciferase reporter gene. The hybrid genes were analyzed for transcriptional activity in human mammary cell lines synthesizing low (HBL-100 and T-47D), moderate (MDA-MB-453), or high (BT-474) amounts of the c-erbB2 mRNA and were also analyzed in HeLa cells. Gene-specific expression was observed, indicating the presence of multiple cis-acting sequences in the c-erbB2 promoter. A major negative element is located in the -2- to -4-kilobase region. It is flanked on both sides by positive elements that display enhanced transcriptional activity in the BT-474 tumor cells only. While predominant in the low-expressing cells, the effect of the repressor appears to be overcome by the distal transactivator in the high-expressing BT-474 cells, resulting in a 15 to 50 times increase in luciferase activity relative to the HBL-100 and T-47D cells, respectively. Cell-specific expression relies on the trans-acting factors present in the different cell lines. The formation of cell-specific protein-DNA complexes was demonstrated by gel retardation assay.

The aim of this paper was to evaluate the long-term (5 years) efficacy of nasal salmon calcitonin in prevention of trabecular postmenopausal bone loss, which was a follow-up of a previously published study (3 years); a randomized, controlled group comparison. One hundred healthy postmenopausal women were randomly chosen from those (186) having completed the 3 year protocol. The 100 women were allocated to an additional 2 year period (total of 5 years) of treatment with either 500 mg d-1, 5 days week-1 of calcium or the same amount of calcium plus 50 IU d-1, 5 days per week of nasal salmon calcitonin, 87 (87%) women complied with the protocol throughout. The main outcome measures were the bone mineral density of the lumbar spine (1-BMD) (DPA) and biochemical parameters reflecting bone turnover (serum alkaline phosphatases, urinary calcium/creatinine and hydroxyproline/creatinine ratios). The women receiving calcium alone presented a significant decrease in 1-BMD after 6 months [-1.6 (0.5)%] [mean(SEM)] (P < 0.01) and this decrease remained significant after 36 months [-6.1(0.8)%] (P < 0.01) and until the end of the trial [-6.6(1.0)% at t60] (P < 0.01). In women receiving calcium and calcitonin, 1-BMD significantly increased after 36 months [+2(0.7%] (P < 0.01) and 42 months [+2.5(0.7)%] (P < 0.01 and was unchanged at the other times of investigation [+1.1 (1.1)% at t60] (NS). The evolution of BMD in the two groups was highly significantly different (P < 0.001) since the sixth month of the study and remained so until the end of the study.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Based on results from the Belgian External Quality Assessment (EQA) Scheme, we studied the main factors affecting the between-laboratory variation of C-reactive protein determination. Participants using homogeneous systems with several calibration points generally achieved better performance. Working temperatures influenced the results to a lesser extent. The present study stresses the importance for EQA organizers to collect more detailed information about CRP analytical methods used by the participants. It also suggests that manufacturers should be more involved in the management of quality, in particular by striving for standardization of the material (kit and calibrator) they produce for CRP assay.

To evaluate the role of carotid surgery in elderly patients 75 years and older, we reviewed 912 carotid endarterectomies performed on 806 patients between 1987 and 1990. There were 151 patients (19% of the whole series) aged 75 years and older (160 endarterectomies, group A), including 29 octogenarians, vs 655 patients under 75 years of age (group B). There were more women in the elderly age group (44%) than in the younger one (38%). Symptoms, risk factors, operative outcome and follow up data of the two groups were compared. The risk profile was similar for the two age groups, with exception for coronary heart disease, less frequent in the older patient group (25% had previous infarction vs 44%). Indication for carotid endarterectomy was different in the two age groups: 41% of group A underwent prophylactic thrombendarterectomy for high degree stenosis, while only 30% of group B had asymptomatic carotid disease. In group A, 6% of the patients had carotid endarterectomy after recovering from a mild stroke, vs 2% in group B. Angiography revealed bilateral carotid disease in 59% of the group A patients (including 15% with contralateral occlusion) vs 40% in group B. Operative mortality was 1.5% for the younger age group vs 2.5% for the older age group. The cause of death was cardiac in 60%. A follow up is available for all patients who benefited carotid endarterectomy since 1976, including 180 patients aged 75 years or older.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Biochemical parameters reflecting bone resorption [urinary calcium/creatinine (Ca/Cr) and hydroxyproline/creatinine (OH/Cr)] were related to serum estrogens [estrone (E1) and estradiol (E2)] in 262 healthy women including 158 patients receiving estrogen replacement therapy (ERT) for at least 6 months, 49 eugonadal women, and 55 untreated postmenopausal women. A significant (P < 0.001) correlation exists between serum E2 and Ca/Cr: Ca/Cr (mg/dl) = -0.00044 E2 (pg/ml) + 0.129 (n = 262; r = -0.37), serum E2 and OH/Cr: (OH/Cr (mg/g) = -0.049 E2 (pg/ml) + 18.76 (n = 262; r = -0.36), serum E1 and Ca/Cr: Ca/Cr (mg/dl) = -0.0003 E1 (pg/ml) + 0.127 (n = 261; r = -0.28) but not between serum E1 and OH/Cr. Women with circulating levels of E2 between 60 and 90 pg/ml have a significant (P < 0.01) reduction of Ca/Cr and OH/Cr when compared with those with lower levels of E2. Higher values of E2 do not provide additional benefit. We conclude that in postmenopausal women receiving an estrogen replacement therapy (ERT), a significant reduction of bone resorption is achieved when circulating levels of estradiol reach a value (60 pg/ml) corresponding to the one measured, in eugonadal women, during the last days of the early follicular phase of the menstrual cycle. We suggest that oral or percutaneous ERT should induce a minimal value of 60 pg/ml to prevent postmenopausal bone loss. [less ▲]

In order to evaluate the potential inhibition of the acute anti-osteoclastic activity of salmon calcitonin (SCT) by specific antibodies (Ab), we compared the SCT-induced hypocalcemic effect in young male rabbits with significant titers of high affinity Ab and in matched animals without Ab. Immunization of rabbits was performed by repetitive s.c. injections of SCT and Freund adjuvant. Ab were present in four-fifths of SCT-treated rabbits (Ab+). Their titer varied from 0.8 x 10(-9) to 30 x 10(-9) M/liter and their constant of affinity from 0.97 x 10(9) to 4.2 x 10(9) L/M. Intravenous injection of 1 IU/kg SCT to Ab+ rabbits induced a significant decrease (P less than 0.01) of ionized serum calcium (Ca2+) after 30 minutes (mean +/- SD: -9 +/- 0.6%) and until the 240th minute of the test (-16.7 +/- 4.7%), with a maximum after 120 minutes (-22.6 +/- 2%). This was not significantly different from the hypocalcemic effect measured after the same procedure performed in matched animals without Ab (Ab-): significant decrease in Ca2+ (P less than 0.01) after 30 minutes (-8.2 +/- 2.2%), maximal after 150 minutes (-23.2 +/- 4.9%), and lasting until 210 minutes (-14.5 +/- 3.7%). We conclude that, in the particular model of the male young rabbit, specific anti-SCT Ab do not block or reduce the acute anti-osteoclastic activity of SCT. [less ▲]

To determine if the occurrence and the consequences of spontaneous predischarge postinfarction ischemia could be predicted early after hospital admission, a consecutive series of patients with acute myocardial infarction was studied and followed for 3 years. No patient was treated by thrombolysis. Spontaneous predischarge ischemia was defined as angina that occurred at rest before hospital discharge, at least 3 days after the acute event, and that was accompanied by electrocardiographic changes, but not by an increase in cardiac enzymes. Patients who died within the first 3 days were excluded from analysis. Among the 943 patients who survived at least 3 days, 165 (17.5%) had spontaneous ischemia before discharge. They had a higher 1-year post-hospital mortality (16 vs. 10%), but did not have significantly higher total 3-year mortality rates. Four independent, early available variables predictive of the occurrence of spontaneous ischemia were selected from a stepwise logistic discriminant analysis: history of angina before infarction, non-Q-wave infarct, absence of smoking, and higher age. Among the 165 patients with spontaneous ischemia, 3 independent variables predictive of 3-year mortality were selected stepwise: left ventricular function score, history of previous infarction, and absence of smoking.

A prognostic index for nonfatal recurrences of ventricular tachycardia (VT) was developed using a retrospective analysis of a group of 206 patients with sustained monomorphic VT or ventricular fibrillation (VF) after healing of acute myocardial infarction. 74 patients (36%) (64 with VT and 10 with VF) had recurrences of sustained monomorphic VT during 3.4 +/- 9 years of follow-up. Three clinical variables were selected and weighted by stepwise logistic discriminant analysis of the study group. They were coded as follows: interval of myocardial infarction to arrhythmia (less than 2 months = 1; 2 to 6 months = 2; greater than 6 months = 3), drug therapy with or without sotalol (with = 1, without = 2), and VT or VF as the presenting arrhythmia (VT = 1, VF = 2). The prognostic index was: 3.41 - (0.56 x interval) - (1.94 x therapy) + (0.86 x arrhythmia). This index was validated prospectively in a test group of 158 consecutive patients with VT or VF after healing of acute myocardial infarction. Patients were allocated into different classes with decreasing prognostic index values associated with increasing risk for recurrences of VT. In the test group, 27 of 158 (17%) patients (22 with VT and 5 with VF) had recurrences of VT (follow-up of 2 +/- 2 years). Two risk classes of patients were identified: high risk for recurrences of VT (61%) corresponding to patients with a negative index; and low risk (4%) consisting of those with a positive index. Thus, using O as the cutoff point, the sensitivity, specificity, and positive and negative predictive values were 81, 89, 62 and 96%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Fifty patients, twenty-five suffering from severe knee osteoarthritis and twenty-five from acute hip osteoarthritis, received pentazocine or a new preparation of tilidine-naloxone for a period of 2 weeks, in a double-blind study. The two drugs were found to have the same efficacy and tolerance in both diseases with a minor but not statistically significant superiority for tilidine-naloxone. Similar quantities of drugs were taken over the study period, while patients were allowed to take as many as 8 capsules per day to relieve pain. There were quite equivalent side-effects and no marked changes in laboratory tests. [less ▲]
