    Plant regulated aspects of nodulation and N2 fixation (1988)

    Notes: Abstract. Root nodule organogenesis is described. Plant regulated aspects of nodulation and N2 fixation are reviewed and discussed. Since the effective N2 fixing symbiosis requires the interaction of the host plant and bacterium in an appropriate environment (the rhizosphere and the root nodule) it is essential that research aimed at improving N2 fixation involve a knowledge and understanding of the plant genes that affect nodule development, growth, and function. Current knowledge of host plant genes involved in N2 fixation is summarized. Various experimental approaches to the study of the host plant's contribution to nodulation are noted. The functions of nodule specific proteins (nodulins) in symbiosis are delineated. Future areas of research are suggested.

    Notes: Summary. Post harvest soil samples taken during the autumn of 1985 and 1986 were split and estimates made of the weed seedbank using two methods: (1) a physical separation of seed from the soil mineral fraction by a sieving/flotation procedure and (2) by placing soil in shallow containers in a greenhouse where seeds could germinate and be periodically counted over a period of eight months. Seedbank estimates derived from each procedure were analysed to determine the suitability of each technique for detecting treatment differences from an experiment evaluating tillage/herbicide effects on weed populations. Both techniques were suitable for determination of seedbank changes due to different tillage treatments and herbicide inputs. The two techniques also proved effective for detection of individual species in the seedbank and the two techniques provided comparable estimates of the relative density of individual weed species in the seedbank. Weed seedbank estimates obtained by the physical extraction procedure from the autumn 1985 soil samples were correlated with weed seedling counts made in the spring of 1986. In most cases, weed seedlings represented less than 10% of the number of seeds estimated by physical extraction the preceding autumn. Individual species seed estimates and subsequent weed counts were poorly correlated which indicated that the seed count estimates alone were poor predictors of weed flora.

    Local infusion of prostaglandin E1 stimulates mandibular bone formation in vivo (1988)

    Notes: The maintenance of alveolar bone is a major clinical objective in dentistry. This is particularly difficult following such local inflammatory episodes as those of periodontitis or the loss of dentition (residual ridge resorption). We present evidence from beagle dogs that local infusion of prostaglandin E1 (PGE) for 3 weeks at doses of 500 to 2000μg per week produces a dramatic, localized formation of alveolar bone in the mandible which exhibits a normal lamellar architecture and mineralization pattern when evaluated by fluorescence microscopy and microradiography. Whether this newly formed bone becomes functionally integrated into the skeleton and can replace bone lost from surgical resections or trauma remains to be established. Nevertheless, these data indicate that predictable local osteogenesis may eventually be produced by infusions of PGE.

    Enprostil inhibits post-prandial gastrin release: a dose—response study (1988)

    Notes: In a double-blind placebo-controlled study in nine healthy volunteers, the effects of single doses of oral enprostil (8.75, 17.5, 35 and 70 μg), taken before a standard breakfast, were assessed on the post-prandial release of gastrin into the plasma. All doses of enprostil caused a significant dose-related decrease in median post-prandial plasma gastrin concentration (range from — 29 to — 44%). In the same subjects, two doses of 25 mg indomethacin caused a significant (38%) increase in median post-prandial plasma gastrin concentration.

    Twenty-four-hour intragastric acidity and plasma gastrin concentration in healthy subjects and patients with duodenal or gastric ulcer, or pernicious anaemia (1987)

    Notes: Twenty-four-hour intragastric acidity and plasma gastrin concentration were measured in healthy subjects (n= 16), and patients with duodenal (n= 12) or gastric (n= 10) ulceration, or pernicious anaemia (n= 8). Median integrated 24-hour intragastric acidity was highest in duodenal ulcer patients and lowest in pernicious anaemia patients (1148 and 0 mmol. hour litre−1, respectively). Median integrated 24-hour plasma gastrin was highest in pernicious anaemia and lowest in the healthy subjects (9886 and 238 pmol. hour litre−1, respectively). Pernicious anaemia patients have unremitting hypergastrinaemia throughout the 24 hours. The results of this study not only provide a reference range of acidity and plasma gastrin in health and disease, but also will act as a baseline for future studies using antisecretory drugs.

    Twenty-four-hour intragastric acidity and plasma gastrin concentration before and during treatment with either ranitidine or omeprazole (1987)

    Notes: Simultaneous 24-hour intragastric acidity and plasma gastrin concentrations were measured in 12 duodenal ulcer patients before and on the twenty-eighth day of treatment with either ranitidine 150 mg b.d. or omeprazole 20 mg o.m. Median integrated 24-hour intragastric acidity was decreased significantly from 1148 to 490 and 36 mmol. hour litre−1 during treatment with ranitidine and omeprazole, respectively, whilst median intragastric 24-hour plasma gastrin was raised significantly from 328 to 799 and 1519 pmol. hour litre−1 respectively. When the results of all 48 experiments were considered together, there was a significant inverse correlation between the 24-hour integrated values for intragastric acidity and plasma gastrin concentration. Both drugs caused a significant elevation of plasma gastrin throughout the 24 hours, although ranitidine had no effect on intragastric acidity from 1900 to 2200 hours. When compared with similar profiles of acidity and gastrin in pernicious-anaemia patients, the modest elevations of plasma gastrin observed in this study suggest that neither drug will be associated with clinically relevant enterochromaffin-like cell proliferation in duodenal ulcer patients.

    The Effect of Bearing Tumours on the Ability of Mice to Reject Bone Marrow Transplants (1988)

    Notes: To examine the possible relationship between the cells mediating resistance to tumour cells and those mediating rejection of foreign bone marrow transplants (BMT), the effect of tumour-bearing on BMT rejection has been measured by means of the spleen colony assay. Moderate doses (〈5.0 × 106) of bone marrow cells from DBA/2 strain mice, which normally produce few haemopoietic spleen colonies in γ-irradiated (950R) CBA/J strain mice, gave numerous (confluent) colonies when given soon after injection of Ehrlich ascites tumour (EAT) cells. Transfusion of [3H]UdR-labelled DBA/2 bone marrow cells demonstrated that the increased spleen colony formation in tumour-bearing mice was not due simply to changes in the total number of injected cells homing to the spleen. Injection of EAT ascites fluid alone, given to CBA/J mice before 950R+BMT, transiently reduced spleen colony development, the effect being more marked when fluid from older tumours was used. Supernatant fluid from EAT cells grown in vitro also depressed growth of BMT in vivo. The results reveal two processes in progress in mice bearing an ascites tumour: (1) an early reduction in the natural resistance to BMT allowing successful grafting and spleen colony formation, and (2) a progressive production by the tumour cells of short-acting soluble factors tending to suppress the proliferation of colony forming bone marrow cells in the transplant. The effect of the tumour-bearing state in weakening the natural resistance to foreign BMT strongly suggests that both tumour and foreign marrow graft resistance are mediated by the same or closely related effector cells.
