    Notes: Summary Managanese deficiency (〈 18 μg g−1 Mn) resulted in decreased levels of phenols in wheat shoots and decreased levels of lignins in both roots and shoots. These observed reductions in phenol contents was due largely to a decrease in the alkaline labile phenol component. Levels of nitrate supplied in solution influenced both phenol and lignin production; high nitrate levels (15 mM) resulted in a reduction in phenol and lignin in the shoot but stimulated lignin production in root tissue.

    Notes: Summary Nine elderly and 11 young hypertensives underwent continuous ambulatory monitoring of blood pressure (BP), assessment of cardiovascular reflexes and M-mode echocardiography as hospital in-patients prior to treatment with once-daily indapamide (2.5 mg). They were followed as out-patients for 4 months during which time casual BP was measured at monthly intervals. The patients were then readmitted to hospital and studied using the same protocol under similar standardised conditions. The results showed that indapamide reduced casual and ambulatory BP in both young and elderly although the most marked effect was seen on systolic BP. Assessment of cardiovascular reflexes indicates that at least part of the hypotensive action of indapamide is due to a diuretic effect. Treatment with indapamide has comparable results on both young and elderly.

    Notes: Summary The hypothesis that wheat plants deficient in managenese are predisposed to infection byGaeumannomyces graminis is outlined, and a test of the hypothesis in a soil system is reported. The results supported the hypothesis: wheat plants growing in managanese-deficient soil, although not showing foliar symptoms, were markedly more susceptible to infection; plant analysis confirmed the nutrient status of the plants. A review of the literature on take-all in wheat coupled with the results of our experiments suggests a reinterpretation of the etiology of this disease, since those edaphic factors which promote infection by this organism are those which also render managese unavailable to the host. Managenese nutrition is proposed as a common factor in many of the environmental conditions which influence the host-pathogen balance.

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The role of acetylator phenotype in determining the response to hydralazine when it was added to diuretic and β-blocker at doses not exceeding 200 mg daily was examined in 57 hypertensive patients. 81% of rapid acetylators needed 200 mg hydralazine daily compared to 38% of slow acetylators (p〈0.01). Despite higher doses of hydralazine the blood pressure was controlled in only 27% of rapid acetylators compared to 65% of slow acetylators (p〈0.02). The relation of acetylator phenotype to blood pressure response was statistically independent of initial blood pressure, age, sex, body weight and serum creatinine (p〈0.005). Current recommendations on hydralazine dosage are unsatisfactory for the 40% of hypertensive patients who are rapid acetylators. We suggest measurement of the acetylator phenotype in patients who respond incompletely to 200 mg hydralazine daily. About 70% of these patients will be rapid acetylators in whom the dose of hydralazine can be increased safely.

    Notes: Summary A multicentre study of 6–10 weeks duration was performed in 60 ambulant hypertensive patients aged over 60 years to compare the efficacy of methyldopa and propranolol with particular reference to the occurrence of cold extremities and sleep disturbances. Blood pressure was effectively controlled by both drugs being reduced from a mean of 180/108 mmHg to 161/93 with methyldopa and 180/108 to 162/94 with propranolol. More patients treated with methyldopa (74%) achieved the target diastolic blood pressure of 95 mmHg or below compared with those treated with propranolol (58%). Side effects were more frequent in the propranolol group necessitating the withdrawal of four patients from the study. Only one patient on methyldopa was withdrawn. The incidence of cold extremities was significantly greater with propranolol. The occurrence of sleep disturbances was similar in both groups. In this group of elderly patients methyldopa was better tolerated than propranolol.

    Notes: Summary Patients with essential hypertension were interviewed prior to entering therapeutic studies in general practice. Patients' age, sex and details of antihypertensive therapy (if any) were noted, as were their spontaneously reported symptoms. Complaints of cold extremities were highest in those taking a beta-blocker (4.1%). Those untreated or taking other therapies complained less often. Those patients taking a beta-blocker with ISA complained less often (3.1%) of cold extremities than those taking a beta-blocker without ISA (5.2%).

    Notes: Summary The efficacy of once-daily bopindolol, a nonselectiveβ-adrenoceptor blocking agent with partial agonist activity, and of pindolol and atenolol in the treatment of essential hypertension has been compared. 369 patients were investigated in a double-blind parallel-group study. The treatment period was 10 weeks. Blood pressure normalisation (diastolic BP equal to or less than 90 mmHg) was to be achieved by a stepwise increase in the dose of the test drugs, and, if required, by addition of a diuretic. Normalisation of blood pressure was achieved in 71 to 76% of the subjects, with no significant differences between bopindolol, pindolol, and atenolol. Special attention was given to evaluation of side effects by using two methods for registration of all adverse events during the study. A low incidence of drug-induced side effects was observed, with no significant difference between bopindolol, pindolol, and atenolol. There was no evidence of unsuspected adverse reactions due to bopindolol.

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary A new vasodilator drug, pinacidil, N″-cyano-N-4-pyridyl-N′-1, 2,2-trimethylpropylguanidine, was studied in an open trial in 15 patients with moderate to severe hypertension. Four patients received pinacidil monotherapy, and in 11 patients it was used with a diuretic or a beta-blocker. In all but one patient normotension was achieved with a mean daily pinacidil dose of 46.7 mg b.i.d. (range 20–100 mg). Side effects were few and were action-related. There was no evidence of early toxicity. Pinacidil is a promising new antihypertensive vasodilator, which deserves further clinical evaluation.

    Notes: Summary Two-dimensional gel electrophoresis of denaturated proteins were performed at five developmental stages or organs (hereafter referred to as stage-organs) on two wheat lines with four different cytoplasms. Five hundred and fifty to 712 reproducible spots were scored depending on the stage-organ. Each stage-organ is unambiguously characterized and several types of control of protein quantity are recorded. Post-translational modifications are hypothetized and may sometimes be stagespecific. Two cytoplasmic patterns are found: one for the euplasmic lines with Triticum aestivum cytoplasm and one for the alloplasmic lines with Aegilops juvenalis, Ae. ventricosa and Ae. kotschyi cytoplasms. Cytoplasmic variation is observed for 28 spots showing position difference, all of which are probably products of the LS gene, and for four spots showing differences for regulation of protein quantity. Nuclear variation between ‘Chinese Spring’ and ‘Selkirk’ is found for 20 allelic differences and for 20 regulatory systems, the latter number being probably underestimated.
