    Notes: Summary The oral bioavailability of methotrexate is variable and may be dose-dependent. The absorption of ‘interval’ oral methotrexate, which is given between cycles of chemotherapy, is unknown. The bioavailability of oral methotrexate has been studied in eight patients, acting as their own controls, to assess the effect of subdivision of the dose, the formulation, and the timing of the methotrexate within the chemotherapy cycle. The mean bioavailability for all the oral methods of administration was 28.2%±3.7% compared with the same dose given IV. Absorption was uninfluenced by subdivision of the dose, liquid or tablet formulation, or administration on day 1 or day 10 of the chemotherapy cycle.

    Notes: Summary A range of clinical and industrial gloves have been evaluated to determine their ability to exclude penetration by cytotoxic drugs. Radiolabelled cyclophosphamide, methotrexate, daunomycin, cytosine arabinoside, and vincristine sulphate were studied in an equilibrium dialysis system in which the glove material was used as the dialysis membrane. The thicker gloves were the most effective, but very little drug crossed any of the gloves tested under laboratory conditions. Further studies to evaluate gloves in conditions of clinical use are now needed.

    Notes: Summary S3341, a new hypotensive agent which binds to alpha2-receptors in animal brain preparations, was studied in normal healthy male volunteers. A dose ranging study with 15 and 25 µg/kg of S3341 was performed in a double blind, placebo controlled randomised and balanced manner with 3 subjects. A decrease or BP without noticeable sedation (assessed by visual analogue scales) was seen. One, 2 mg of S3341, 0.1 and 0.2 mg of clonidine were then compared in a double blind, placebo controlled, randomised and balanced manner in 10 subjects. BP, heart rate, systolic time intervals (STI), critical flicker frequency, choice reaction time, pursuit rotor, stimulated salivary volume, and dryness of mouth and sedation with visual analogue scales, were measured at 0, 1.5, 3.0, 4.5 and 6.0 h after drug administration. The relationship between decreases in BP and sedation was assessed by linear regression analysis, with the former as the independent (predictor) response and the latter as the dependent (response) variate. Both drugs produced a similar decrease of BP which was significantly different from placebo. Changes in psychomotor function tests were not significant. Both drugs produced dryness of mouth and sedation which were significantly different from placebo but changes were less with S3341. Clonidine showed a significantly steeper slope than S3341 in the relationship between decreases in BP and sedation. This must be interpreted with caution as there was wide variation in the correlation between decreases in BP and sedation, but it may be possible to achieve lesser sedation with S3341.

    Notes: Summary Ten patients with moderate to severe Raynaud's syndrome were recruited into a four week randomised double blind crossover study to compare the efficacy of UK-38,485 50 mg, a new thromboxane synthetase inhibitor with that of placebo. With the doses used there was no significant difference between the two treatment periods in the number, severity and duration of ischaemic attacks, the mean hand temperatures, forearm and digital blood flow and red blood cell rheology.

    Notes: Summary High affinity stereospecific binding sites for L-glutamate have been reported in several regions of mammalian brain. The binding sites in the hippocampus and cerebellum have been studied more extensively than binding in other brain regions. The hippocampal and cerebellar binding sites show similar properties with respect to their pharmacology and their independence of Na+. There is evidence, particularly good in the case of hippocampus, of mechanisms that may regulate the availability of the binding sites in both brain areas. Some progress has been made with the isolation of the hippocampal binding site but the protein has not been extensively characterised. In the case of insect muscle, high-affinity stereospecific binding of L-glutamate to whole membrane preparations, to detergent-solubilised membranes and to isolated proteolipids has been reported. Much greater variability in the binding characteristics is seen than is the case with the mammalian brain preparations. Preliminary experiments suggest that at least four distinct binding sites may be present on insect muscle. The complete characterisation of glutamate binding sites is at present precluded by a lack of potent agonists and antagonists. However, recent advances in the pharmacological classification of receptor sites for the excitatory amino acids in mammalian brain could provide sufficient information to permit the identification of the binding sites as synaptic receptors. Invertebrate toxins whose site of action is the insect neuromuscular junction may well prove to be useful tools with which to isolate and characterise the synaptic receptor proteins.

    Notes: Abstract A new albinistic allele in the cat is described and designated blue-eyed albino (symbol c a ). The coat is completely white. The eyes possess a dull red pupil in reduced light and a pale translucent blue iris. Reasons are given for regarding the allele as less extreme than complete albinism. The inheritance of three members of the albino series in the cat has now been reported. In decreasing order of dominance these are full colour (C), Burmese (c b ), Siamese (c s ) and blue-eyed albino (c a ).
