    Notes: Abstract. A neuroendocrine peptide of the Leu-callatostatin family, LPVYNFGL-NH2, has been isolated from tissue extracts of 5th instar larvae of the codling moth, Cydia pomonella (Lepidoptera). It is identical to a peptide previously isolated from the blowfly, Calliphora vomitoria (Diptera). The distribution of this peptide within the tissues of C. pomonella has been mapped by immunocytochemistry using antisera raised against LPVYNFGL-NH2. Midgut endocrine cells contain Leu-callatostatin immunoreactivity, as do several paired Leu-callatostatin neurones in the brain and ventral nerve cord. Within the visceral nervous system, the frontal ganglion contains four Leu-callatostatin neurones. Axons from these cells combine with others originating from neurones in the brain and project within the nervi cardiostomatogastrici to innervate the tissues of the foregut. In particular, the oesophageal valve has a prominent ring of Leu-callatostatin-immunoreactive fibres. The synthetic peptide, LPVYNFGL-NH2, has a potent reversible inhibitory effect in vitro on all visible forms of spontaneous contractile activity of the foregut, including closure of the oesophageal valve. Complete myoinhibition is observed at peptide concentrations from 10−10 to 10−16 M. These results, in conjunction with the results of similar studies on cockroaches, crickets and flies, suggest that the Leu-callatostatins are a ubiquitous family of insect neuroendocrine peptides with an important role in the control of gut motility.

    Notes: Abstract: The estimation of glomerular filtration rate is important for the medical treatment of patients with rheumatoid arthritis (RA). However, the determination of endogenous creatinine clearance (Clcr) from a 24-h urine collection is an unreliable and time-consuming procedure. We therefore tested the accuracy of six equations and one nomogram for the prediction of Clcr from serum creatinine (Scr) in 38 patients with RA and 20 controls. A positive correlation was found for all methods in the controls (r= 0.83–0.94) and RA patients (r= 0.51–0.69). The methods did not overestimate Clcr in RA. In the RA group the simple formula published by Cockcroft [Clcr = ((140 − age) × body weight)/(72 × Scr), × 0.85 for females] showed the best correlation with the measured Clcr. In RA the Cockroft formula can reliably be used to predict Clcr from Scr.

    Notes: Abstract: Over the past 25 years, nailfold capillary microscopy (NCM) has gained diagnostic value in the field of rheumatology based on descriptive data from patients with distinct connective tissue diseases (CTD). We prospectively analysed NCM findings from 116 patients selected for NCM by one of the following indications: (1) suspected diffuse or limited scleroderma or dermatomyositis, (2) evaluation of Raynaud’s phenomenon (RP) or (3) suspected small-vessel vasculitis. Nailfold haemorrhages, and enlarged and tortuous nailfold capillaries (‘lupus pattern’) were found to comparable degrees in patients with CTD and primary RP. Only giant loops, bushy capillaries and avascular areas indicated CTD; 92% of patients with Wegener’s granulomatosis (WG) had avascular areas. From all nailfold capillary abnormalities, only bushy capillaries, giant loops and avascular areas support a suspected CTD. A lupus-like pattern is not diagnostic. Avascular areas are a typical abnormality in patients with WG, for which NCM findings have not been described previously.

    Description / Table of Contents: Corrosion Testing of Paints with the Aid of AerosolsIt is well known that opinions differ considerably about the value and usefulness of accelerated tests. On the other hand, it has been proved that the use of genuine aerosols for the corrosion testing of protective paints offers advantages as the testing technique is derived from the salt spray test. Spraying is not carried out by means of jets bat with the aid of suitably constructed aerosol as is used, for instance, in air conditioning. A 0,05 % solution of NaCl with a CO2 addition of 1 litre/hour is recommended as test medium. The corrosion test can be intensified by adding aggressive gases like CO2, HCl, NH3 and SO2.
    Notes: Bekanntlich gehen die Ansichten über Wert und Zweckmäßigkeit von Kurzzeitprüfungen stark auseinander. Dagegen ist erwiesen, daß die Verwendung echter Aerosole für die Korrosionsprüfung von Schutzanstrichen Vorteile bietet, wobei das Prüfverfahren den Methoden des Salzsprühtestes entstammt. Hierbei wird von einer Versprühung mit Düsen abgesehen und ein entsprechend konstruierter Aerosolapparat verwendet, wie er z. B. für die Raumlufterzeugung verwendet wird. Als Prüfmittel wird eine 0,05%-ige NaCl-Lösung mit einem CO2-Zusatz von 1 l/h empfohlen. Durch aggressive Gase wie CO2, HCl, SO2, NH3 läßt sich die Korrosionsprüfung verschärfen.
