This review surveys the discovery of endogenous alkaloids in mammals. The formation of morphine in mammalian brain was assumed in 1970. The existence of morphine was demonstrated by radioimmunoassay. Identification of morphine was performed by spectroscopic methods. The isolation of mammalian morphine raises the question of biosynthesis.

Morphine-Induced Attenuation of Morphine Tolerance
Science, 1981Rats experienced both morphine and an environmental cue, but the cue always signaled a drug-free period. They were subsequently administered morphine in the presence of the cue, and the development of analgesic tolerance was assessed. The prior experience retarded such tolerance.

Acta Anaesthesiologica Scandinavica, 1997
Morphine is a potent opioid analgesic widely used for the treatment of acute pain and for long‐term treatment of severe pain. Morphine is a member of the morphinan‐framed alkaloids, which are present in the poppy plant. The drug is soluble in water, but its solubility in lipids is poor.In man, morphine‐3‐glucuronide (M3G) and morphine‐6‐glucu‐ronide ...

Morphine preexposure facilitates morphine place preference and attenuates morphine taste aversion
Pharmacology Biochemistry and Behavior, 2005Repeated morphine preexposure has been reported to enhance measures of morphine reward (conditioned place preference; CPP) and attenuate measures of morphine aversion (conditioned taste aversion; CTA). These effects are generally independently assessed, limiting the ability to determine if the enhancing and attenuating effects of morphine exposure are ...

Morphine preference in rats previously morphine dependent
Pharmacological Research Communications, 1984Morphine preference and tendency to relapse to morphine tolerance and dependence were studied in rats which were previously made morphine dependent. Tolerance to, and physical dependence on, morphine were initially produced by administration of increasing concentrations of morphine sulphate in 5% sucrose solution for 3 weeks.

Morphine Metabolism and Morphine Tolerance in Goldfish
Anesthesiology, 1970Tolerance to morphine was induced in goldfish shown to be unable to metabolize morphine. Ability to metabolize is, therefore not a prercquisite to development of tolerance.

Journal of the American Medical Association, 1925
My object in this paper is to call the attention of the surgical profession to the great diversity of opinion that exists regarding the use of morphin before and, especially, after operation. It would seem that our knowledge of the pharmacology of morphin, which has been used for several hundred years, would lead to absolute unanimity on the subject ...
