    Notes: Breeding planning and variety valuation can be supported only if weighting factors for the economically relevant performance traits are available. In plant breeding they are necessary for the calculation of selection indices as well as for the comparison of varieties and for quantifying the monetary impact of breeding progress.In this article the economic weights for the most important performance traits of sugar beet are calculated from the farmer's, the sugar factory's, and the national economy's point of view. Based upon economic weights for beet yield, sugar content, potassium, sodium, and ammo nitrogen content, a total of 19 varieties was compared with regard to physical and economic performance. The investigation shows that “best” and “worst” varieties differ in gross margin per ha by 270.— to 330.— DM.Indications were given for possibilities and limitations of the application of economic weights in breeding planning.

    Notes: Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) Karst.) and Sitka spruce (Picea sitchensis Bong. Carr.) were planted as 2-year-old seedlings in an open-air fumigation facility at Liphook in southern England in March 1985. The soil was a humoferric podzol of pH 4. SO2 fumigation began in May 1987 and continued until December 1990. Long-term mean SO2 concentrations were 4,13 and 22 nmol mo−1. Three plots, one at each SO2 level, were also exposed to O3 at an average of 1–3.times the ambient level. O3 fumigation ran from March to December 1988, May to December 1989 and February to December 1990. Each species reacted differently to treatment. Scots pine showed no growth response to either pollutant, although other work on the site demonstrated a number of deleterious effects of SO2 on this species, including increased leaf loss and foliar injury. Stem basal diameter growth of Norway spruce was depressed in SO2-treated plots. In contrast, extension growth of shoots of Sitka spruce increased in SO2-treated plots, in apparent response to codeposition of NH3-N. However, diameter growth of Sitka spruce main stems did not increase. No effects of O3 on growth were recorded for any species.

    Notes: The effect of increasing doses (15 mg, 30 mg and 60 mg) of the substituted benzimidazole, AG-1749, on gastric acid secretion and fasting serum gastrin concentration has been studied after repeated administration to healthy volunteers.AG-1749 produced a dose-dependent and profound decrease in basal and stimulated gastric acid secretion in all volunteers, with almost total suppression at the highest dose. The extent of inhibition increased between Day 2 and Day 8 with the 15 and 30 mg doses of AG-1749. The inhibitory effect of AG-1749 appears to be fully reversible as control levels of acid output were reached 7 days after drug withdrawal.Seven days’dosing with 60 mg AG-1749 induced a more than threefold increment of fasting serum gastrin concentration, but this increase was still within the normal range. Seven days after cessation of dosing, fasting serum gastrin concentration returned to a pre-dose level.

    Notes: There are two major principles of ulcer therapy. Today, the most widely accepted drugs are those which substantially reduce aggressive factors (i.e. acid and pepsin), namely histamine H2-receptor antagonists, antimuscarinics and antacids. Less frequently applied are mucoprotective agents like colloidal bismuth compounds and sucralfate. Prostaglandins both reduce acid secretion substantially and are believed to enhance mucosal resistance. Their anti-ulcer efficacy, however, is solely explicable by their antisecretory activity. Although mucosa-strengthening agents and H2-receptor blockers have nearly identical healing rates, mucosa-strengthening agents have inconvenient dosage regimens (four times or twice daily) and are probably less effective in relieving pain. The same holds true for antacids. Prostaglandins, antimuscarinics and antacids have dose related side effects. In contrast, H2-receptor blockers are characterized by a clear mechanism of action, convenient dosage regimes, good tolerance and a low incidence of side-effects. H2-receptor antagonists are the most effective anti-ulcer drugs presently available.

    Notes: One hundred and twenty-five patients with duodenal ulcer disease were given continuous ranitidine therapy after initial acute healing. Cumulative remission rates indicated that 95 % of patients were ulcer-free after 1 year, 89% at 2 years, 81% at 3 years, 70% at 4 years and 60% at 5 and 6 years. Nine patients had a second recurrence after healing of the first. No patient developed an ulcer complication. These results support the view that long-term continuous ranitidine therapy prevents ulcer recurrence and complications.

    Notes: Pentagastrin stimulated gastric secretion was measured in 12 healthy male subjects after repeated once daily oral administration of 20 and 40 mg BY 1023/SK&F 96022 – a new substituted benzimidazole derivative.Twenty milligrams inhibited acid output compared with placebo by 24% (2.5–3.5 h) and 26% (24.5–25.5 h) after the first oral intake. Inhibition increased to 56% and 50%, respectively, after the seventh oral dose. Forty milligrams inhibited acid output by a mean of 51% (2.5 to 3.5 h) and 52% (24.5–25.5) after the first oral intake. After the seventh dose mean inhibition rose to 85% and 66%, respectively.

    Notes: The effects of the H+, K+-ATPase inhibitor BY 1023/SK&F 96022 on pentagastrin-stimulated acid secretion have been studied in healthy male volunteers (n= 12). The gastric acid response to submaximal pentagastrin-stimulation (0.6 μg/h/kg b.w.) was dose-dependently inhibited. A single dose of 5 mg decreased acid output by 22% while after 60 mg and 80 mg secretion was almost completely abolished.A good dose linearity was observed for AUC (0, 〉) and Cmax over the dose range from 5 to 80 mg. Elimination half-life, total clearance and volume of distribution of the parent compound were independent of the dose.The drug was well tolerated up to the highest dose of 80 mg. No clinically relevant influence was found on either laboratory screen or cardiovascular parameters.

    Notes: Lansoprazole (AG 1749) is a novel substituted benzimidazole which inhibits gastric acid secretion by blocking H+, K+-ATPase. This randomized, double-blind multicentre trial studied the dose–response relationship of lansoprazole on ulcer healing and compared it with ranitidine in 314 out-patients with endoscopically assessed, symptomatic duodenal ulcer. Cumulative healing rates with Lansoprazole 7.5, 15, and 30 mg o.m. were 48, 59, and 74% at 2 weeks and 75, 84, and 95 % at 4 weeks, respectively (intention-to-treat); the difference of the healing rates between 7.5 and 30 mg groups was significant (P 〈 0.001).Corresponding healing rates for 300 mg ranitidine nocte were 51 and 89 %. Pain relief was similar in all treatment groups. Lansoprazole was well tolerated. During a follow-up of 6 months relapse rates after lansoprazole 7.5, 15, and 30 mg were 21, 29, and 22%, respectively; the relapse rate after ranitidine 300 mg was 20%. In conclusion, lansoprazole provides faster healing of duodenal ulcer than ranitidine and a similar relapse pattern. For further trials in peptic ulcer disease a daily dose of lansoprazole 30 mg o.m. is recommended.
