  • Nietzsche and Psychedelics – Peter Sjöstedt-H –
    Antichrist Psychonaut: Nietzsche and Psychedelics – Peter Sjöstedt-H – ‘… And close your eyes with holy dread, For he on honey-dew hath fed, And drunk the milk of Paradise.’ So ends the famous fragment of Kubla Khan by the Romantic poet, Samuel Taylor Coleridge. He tells us that the poem was an immediate transcription of an opium-induced dream he experienced in 1797. As is known, the Romantic poets and their kin were inspired by the use of psychoactive substances such as opium, the old world’s common pain reliever. Pain elimination is its negative advantage, but its positive attribute lies in the psychedelic (‘mind- revealing’)1 state it can engender – a state described no better than by the original English opium eater himself, Thomas De Quincey: O just and righteous opium! … thou bildest upon the bosom of darkness, out of the fantastic imagery of the brain, cities and temples, beyond the art of Phidias and Praxiteles – beyond the splendours of Babylon and Hekatómpylos; and, “from the anarchy of dreaming sleep,” callest into sunny light the faces of long-buried beauties … thou hast the keys of Paradise, O just, subtle, and mighty opium!2 Two decades following the publication of these words the First Opium War commences (1839) in which China is martially punished for trying to hinder the British trade of opium to the Chinese people. Though opium, derived from the innocent garden poppy Papavar somniferum, may cradle the keys to Paradise it also clutches the keys to Perdition: its addictive thus potentially ruinous nature is commonly known. Today, partly for these reasons, opiates are mostly illegal without license – stringently so in their most potent forms of morphine and heroin.

  • Canine Status Epilepticus Care
    Vet Times The website for the veterinary profession https://www.vettimes.co.uk CANINE STATUS EPILEPTICUS CARE Author : Stefano Cortellini, Luisa de Risio Categories : Vets Date : August 2, 2010 Stefano Cortellini and Luisa de Risio discuss emergency management techniques for a condition that can claim the lives of 25 per cent of afflicted dogs – as the quicker the start of treatment, the better the chances of control STATUS epilepticus (SE) is a neurological emergency with a mortality of up to 25 per cent in dogs (Bateman, 1999). SE can be defined as continuous epileptic seizure (ES) activity lasting longer than five minutes, or as two or more ES with incomplete recovery of consciousness interictally. SE has also been defined as continuous seizure activity lasting for 30 minutes or longer. However, emergency treatment to stop the ES should be administered well before the defined 30-minute time. The most common type of SE is generalised tonic-clonic status. When this is prolonged, the tonic- clonic clinical manifestations can become subtle, with only small muscle twitching and altered mentation. This status is called electromechanical dissociation, as continued abnormal electrical activity in the brain persists while the motor manifestations are minimal to absent. In these cases, emergency anti-epileptic treatment is necessary as for tonic-clonic status. SE can be divided into two stages. The first stage is characterised by generalised tonicclonic seizures and an increase in autonomic activity that causes tachycardia, hypertension, 1 / 7 hyperglycaemia, hyperthermia and increased cerebral blood flow. The second stage of SE starts after about 30 minutes and is characterised by hypotension, hypoglycaemia, hyperthermia, hypoxia, decreased cerebral blood flow, cerebral oedema and increased intracranial pressure.

  • Studies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (II) Composition of Salt in Anode Compartment
    Journal of NUCLEARSCIENCE and TECHNOLOGY,7 (10), p. 522~526 (October 1970). Studies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (II) Composition of Salt in Anode Compartment Yoshinobu YAMAMURA* and Shin SUZUKI* Received May 13, 1970 Accurate knowledge on the salt composition in the anode compartment is indispensable when 6Li is to be highly enriched by electromigration in fused LiBr-KBr mixture. A study was made on the dependence on temperature shown by the salt composition in the anode com- partment. It was observed that sustained electromigration led to a salt composition in the anode compartment that was determined by the prevailing temperature. The composition was observed for various temperatures between 380- and 740-C: In terms of the ratio Li/K in chemical equivalent, the values were 1.31 at 380-C, 1.29 at 420-C, 1.31 at 460-C, 1.41 at 500-C, 1.76 at 540-C, 1.82 at 580-C, 1.95 at 620-C, 2.16 at 680-C and 2.34 at 740-C. These results can be explained by assuming that the fused LiBr-KBr mixture is a system composed of two simple salts and their eutectic, and that at temperatures below 550-C, which is the melting point of LiBr, LiBr and KBr are dissolved in fused eutectic, while KBr is dissolved in the fused eutectic and LiBr at temperatures between 550- and 738-C, which latter is the melting point of KBr.

  • Bromides Potassium Bromide, Sodium Bromide Kbr and Nabr Are Other Names for This Medication
    Bromides Potassium Bromide, Sodium Bromide KBr and NaBr are other names for this medication. How Is This Medication Useful? • Potassium bromide or sodium bromide are used to treat dogs with epilepsy, either alone, or in combination with other drugs. • They are used in cats with epilepsy on if other drugs fail to work well. • Bromides are a chemical rather than an FDA approved drug. American Chemical Society (ACS) grade bromide should be used for seizure therapy. Are There Conditions or Times When Its Use Might Cause More Harm Than Good? • Bromides must be eliminated from the body by the kidneys. Animals with severe kidney disease may have problems with this drug, if they don’t make enough urine. • Human infants have suffered growth retardation when born to mothers who took bromides. Potassium bromide should probably not be used in pregnant or nursing mothers unless the benefit of use outweighs the risk of adverse effects. • The intake of chloride will have to be very carefully controlled while your animal is on this drug. Do not give your animal any salty treats and always check with your veterinarian before giving new foods or snacks while on this medication. • If your animal has any of the above conditions, talk to your veterinarian about the potential risks of using the medication versus the benefits that it might have. • Some cats can develop fluid in the lungs while taking bromides and cats who are taking bromides should do so only when seizures can not be controlled by other drugs, and only if carefully monitored for breathing problems.
