    Notes: The incidence of thrombocythaemia (a platelet count 〉600×l09/l) in a 10-year survey was 7 per 106 population per year (R. M. Pettit, personal communication). It is generally a disease of late middle age, but a second population of young and mainly female patients has been described (Hoagland & Silverstein 1978). An increased platelet count can be secondary (after splenec-tomy, associated with inflammation, malignancy or iron deficiency) or due to a primary myeloproliferative disorder. We describe four patients in whom a series of miscarriages before 20 weeks gestation appears associated with thrombocythaemia and estimate the prevalence of this association in patients with unexplained repeated miscarriage.

    Notes: A case of prolonged action of suxamethonium in a patient with gestational trophoblastic disease is reported. Postoperatively the patient was found to have markedly reduced plasma cholinesterase activity (363 IU/litre) with a normal cholinesterase phenotype. Consequently plasma cholinesterase activity and phenotype were measured in six other patients with the condition and these results compared with those of 22 patients with normal first trimester pregnancies undergoing therapeutic abortion. Plasma cholinesterase phenotype was normal in all patients studied. The activity was significantly decreased (p 〈 0.05) from the normal range (620–1370 lU/litre) in all patients with trophoblastic disease. In the 22 patients with normal pregnancies, 14 had activity values in the abnormal range (〈 620 IU/litre) while the mean cholinesterase activity of the group as a whole was significantly decreased (561.8 IU/litre, p 〈 0.05) below the normal range. These results confirm the presence of a decrease in plasma cholinesterase activity in early pregnancy and provide new evidence for a decrease in activity in a pseudopregnancy state.

    Notes: Eighty newborn babies were studied by ultrasound brain scan before and after their first general anaesthetic. Periventricular haemorrhage or ischaemia occurred in 23 patients (29%) and affected both term and premature babies. Four new lesions developed but only three of 19 existing lesions deteriorated. The very premature (〈 33 weeks gestation) were most at risk (four of eight deteriorated). Deterioration or development of lesions occurred only in very ill babies with known risk factors. Anaesthesia did not appear to be implicated in any case.

    Notes: Abstract Strings of moored sediment traps were deployed in a 150 m water column over a period covering the growth and collapse of the spring bloom (4 April–3 June 1976) in an area of the northern North Sea. The efficiency of collection of material in the moored traps was compared to collections in free-drifting traps in the same area of deployment. The ways in which the data from the trap collections may be interpreted was considered at some length and a best estimate of the flux of organic carbon and nitrogen to the sediment was made. For the period prior to the spring bloom (4–23 April) this flux was 50 mg C m−2 d−1 (about 20% of primary production). During the bloom (24 April–19 May) it was about 185 mg C m−2 d−1 (35% of production) and during early summer (20 May–3 June) it was 115 mg C m−2 d−1, about 25% of the overlying production. The organic carbon and nitrogen content of the material collected was measured and the material was examined microscopically. There was evidence of a large settlement of diatoms immediately after the spring bloom which was reflected in changes in the C:N and C:chlorophyll ratios of the material collected. This change in biochemical composition of the material may affect its nutritional quality and have a stimulatory effect on the growth and reproduction of the animals living in the sediment.

    Notes: Abstract Previous studies have shown that severe neonatal asphyxia and hypoxia lead to a redistribution of cerebral blood flow (CBF) with a preferential perfusion of the brain stem. The present study shows that this mechanism is operative also in moderately hypoxic newborn lambs (oxygen saturation 32.7–65.2) with a threshold of about 25% reduction in oxygen saturation. In hypoxia, the mean increase in total CBF, brain stem and telencephalic blood flow was 44%, 68% and 43%, respectively (five lambs). We found that naloxone reverses this redistribution, and that the effects of naloxone on telencephalic perfusion and cerebral metabolic rate of oxygen (CMRO2) were proportional. In hypoxia + naloxone (1 mg/kg), a further increase in total CBF, brain stem, and telencephalic blood flow of 30%, 7% and 31% was noted. We therefore suggest that the redistribution of CBF is an important opioid-mediated homeostatic mechaism, which diminishes the metabolic requirements of the newer part of the brain in hypoxia and allows a preferential perfusion of the vital structures of the brain stem.

    Notes: Abstract This paper describes an experimental and theoretical study of the torsional vibrational properties of rubber cylinders. Experiments were carried out on long cylinders using a modified Weissenberg Rheogoniometer. A comparison is made with a theory based on a modified generalized Maxwell model.
