    Notes: A case of Whipple's disease is described where the lymphatics in the regional lymph nodes appear to be obstructed by embolized macrophages, containing the characteristic PAS positive bacillary material. It is suggested that the regional lymphangectasia in Whipple's disease may in part result from such cellular embolism.

    Notes: Eighty-eight patients in ASA classes 1 or 2 and aged between 18 65 years, who were to undergo anaesthesia, were allocated randomly to a group with or without an airway. Methohexitone, nitrous oxide, alfentanil and enflurane were used, with the patients breathing spontaneously. This study showed that there was no significant difference between the two groups in the incidence of sore throat, or any other related symptom, and concludes that the use of an oropharyngeal airway does not increase morbidity among nonintubated patients.

    Notes: Summary The indications and results of transsphenoidal surgery for pituitary adenomas are analysed. The advantages and disadvantages of Bromocriptine and radiotherapy are considered. Transsphenoidal surgery does not damage pre-existing pituitary function. It produces excellent results in micro and mesoadenomas, curing about 70–80% of patients irrespective whether the tumour produces ACTH,prolactin or growth hormone. Moreover there is a very small relapse rate. Macroadenomas of non-functioning type are also well treated by transphenoidal surgery, with a small recurrence rate as judged by CT scan follow-up. But macroadenomas secreting prolactin or growth hormone are less effectively treated by transsphenoidal surgery, only about 40% being cured. Invasive macro prolactinomas are not helped by surgery and should be treated with Bromocriptine and radiotherapy. Radiotherapy should be used sparingly and has inevitable complications. Post-operative delayed visual deterioration is caused either by recurrent tumour or radiotherapy. There is no good evidence to support the secondary empty sella syndrome as a cause of such delayed visual deterioration.

    Notes: Summary Several studies have shown the use of non-radioactive labelled DNA probes for in situ hybridisation, mainly to identify cellular DNA. In this study mRNA in situ hybridisation was performed on rat pituitary with biotinylated complementary (c) RNA probes for rat prolactin and growth hormone (GH), and compared with radioactive 35S-radiolabelled probes. Biotinylated cRNA probes were labelled with either biotin-11-UTP or with allylamine-UTP, the latter method being able to produce a higher yield of labelled RNA. Different detection systems were tested, and hybridisation signal was seen in cells of anterior pituitary with both types of biotinylated probes. The signals were detected using either avidin-biotin-complex with peroxidase (ABC), peroxidase-anti-peroxidase (PAP) or gold-silver methods. ABC peroxidase detected using glucose oxidase-diaminobenzidine (DAB)-nickel solution appeared to be the best method for detecting labelled RNA probes, with very strong signal and low background. The biotinylated probes were comparable in sensitivity to the radiolabelled probes in detecting prolactin and GH mRNAs in the anterior lobe of the rat pituitary. These results indicate an alternative methods of labelling and detection of biotinylated probes which could have a potential role in research and diagnostic techniques.

    Notes: Summary Luteinizing hormone (LH) binds to the Leydig cells of several mammalian species where it stimulates steroidogenesis, protein synthesis and protein phosphorylation. In the present study, standard immunoperoxidase (PAP) and avidin-biotin complex (ABC) techniques were used to detect the binding of endogenous and exogenous LH to the epididymis of the mature mouse. Throughout the epididymal duct, a positive reaction for peroxidase, indicating LH binding, occurred in the Golgi area of principal cells. In segment 1, positive reactions were also visualized in the perinuclear area and in the region located between the Golgi area and the apical surface of the principal cells (supra-Golgi area). In the corpus and cauda epididymidis, scattered entire principal cells were also positive. Throughout the epididymal duct, the reactions indicating the binding of exogenous LH were more intense than those of endogenous LH. The significance of LH binding to the epididymis is uncertain but LH may perform the same functions in epididymal principal cells as it does in Leydig cells.

    Notes: Abstract Phosphoenolpyruvate carboxylase (PEPCase; EC 4.1.1.31) from Flaveria trinervia Mohr (C4), F. floridana Johnston (C3−C4), and F. cronquistii Powell (C3) leaves were compared by electrotransfer blotting/enzyme-linked immunoassay (Western-blot analysis), mobility of the native enzyme in polyacrylamide gels and in isoelectric focusing (IEF) gels, peptide mapping, and in-vitro translation of RNA isolated from each plant. The PEPCases from the C3 and C3−C4 plants were very similar to each other in terms of electrophoretic mobilities on gels and isoenzyme patterns on IEF gels, and identical in peptide mapping. Quantitative differences were noted, however, in that the C3−C4 intermediate plant contained more PEPCase overall and that the relative activity of individual isoenzymes shifted between the C3 and C3−C4 intermediate PEPCases. The PEPCase from the C4 plant had a different isoenzyme pattern, a different peptide map, and was far more abundant than the other two enzymes. Western blot analysis demonstrated the cross-reactivity of PEPCases from all three Flaveria species with antibody raised against maize PEPCase. The results provide evidence, at the molecular level, that supports the view of C3−C4 intermediate species as C3-like plants with some C4-like photosynthetic characteristics, but there are differences from the C3 plant in the quantity and properties of the PEPCase from the C3−C4 intermediate plant.

    Notes: Summary The complete sequence of a sunflower (Helianthus annuus) gene, HaG5, encoding a 2 S albumin storage protein was determined. The predicted unprocessed precursor has 295 amino acids, is rich in glutamine residues (24%) and contains a hydrophobic amino-terminus that is similar to the consensus signal peptide. Amino acid sequencing of the mature protein revealed extensive post-translational processing. Nuclease protection and primer extension analysis indicated a major transcriptional start 30 nucleotides 5′ of the predicted ATG start codon. Additional sequence data, determined from a nearly full length cDNA recombinant, indicate that HaG5 is a member of a small gene family comprised of at least two divergent genes. Comparison of the predicted HaG5 gene product with sequences of other known plant proteins revealed distant but significant homology with the napins of Brassica and other heterogeneous seed proteins in the albumin superfamily.

    Notes: Abstract The abilities of foliage of selected agricultural crop and native boreal forest species to neutralize acidic raindrops were compared. The species differed widely in their responses. Neutralization was influenced to a large extent by leaf wettability and was poorly related with species' susceptibility to foliar injury from acid rain sprayings. Little neutralization of pH 3.0 droplets occurred on very waxy leaves, e.g. cabbage (Brassica oleracea L.), due to the small contact area between the leaf surface and raindrops. In contrast, on sunflower (Helianthus annuus L.) and radish (Raphanus sativus L.) leaves, which are pubescent and easily wettable, neutralization was considerable. For all agricultural crop species examined, the pH of droplets drying on cotyledons was consistently higher than on the leaves. The pH values of raindrops were also higher when the foliage was injured by the acid rain, probably due to leakage of cellular contents. Among boreal forest species examined, bunchberry (Cornus canadensis L.) was particularly good at neutralizing natural acid rain, increasing the pH from 3.9 to 6.6 after 9 hr of foliar contact, while the response of other boreal species ranged from a final pH of 4.8 to 5.7 under the same conditions. Simulated raindrops on wild sarsaparilla (Aralia nudicaulis L.) were never neutralized but increased in acidity as they evaporated. Chemical analyses of droplets collected from foliage showed calcium (Ca) and potassium (K) to he the major cations entering the neutralized droplets. Neutralization of acidic raindrops appears to occur through two processes: solubilization of alkaline dusts and exudates on the leaf surface, and ion exchange removal of H+ by the foliage.
