The escape reaction time (ERT) of the cricket Pteronemobius sp. from the heated box begins at 48 degrees and increases with temperature until 56 degrees C, beyond which there is no further increase. The ERT (2.2 +/- 1.39 s) from the hot box at 54 degrees C is used as a model for studying the analgesic effects of opiates. Results of the present paper show that the ERT did not change after injecting the insect in the abdominal haemocoel with 0.9% saline solution, but ERT increased when 0.32, 0.52… Expand
The effect of opioids and their antagonists on the nocifensive response of Caenorhabditis elegans to noxious thermal stimuli
TLDR
The effect of the opiate morphine and opioid neuropeptides Endomorphin 1 and 2 on the thermal avoidance (Tav) behavior of Caenorhabditis elegans is explored and Naloxone and CTOP were tested in combination with the drugs. Expand
Effects of Peptide and Non-Peptide Opioids on Protective Reaction of the Cockroach Periplaneta americana in the “Hot Camera”
TLDR
An important role of the endogenous opioid system in control of protective behavior of insects, as well as heterogeneity of the receptor components of the system are indicated. Expand
Effects of several exorphins and endorphins on the escape reaction of the cockroach Periplaneta americana under elevated temperature conditions
TLDR
It has been shown that ED50 decreases statistically significantly with increase of the length of the peptide molecule and its affinity to opioid receptors of the κ-type, which might indicate a specific ability of some plant proteins to regulate (decrease) the insect protective behavior. Expand
Modulation of the escape response by [d-Ala2]Met-enkephalin in the crab Chasmagnathus
TLDR
Evidence for different degrees of opiate sensitivity among crabs of the same population in relation to their different degree of reactivity to the visual danger stimulus is presented. Expand
Altered heat nociception in cockroach Periplaneta americana L. exposed to capsaicin
TLDR
The research demonstrated suppression of the heat sensitivity by repeated capsazepine, camphor and capsaicin administration in the American cockroach and showed that behavioral thermoregulation in normal temperature ranges is altered in treated cockroaches, which displayed a preference for warmer regions compared to non-treated insects. Expand
In search of evidence for the experience of pain in honeybees: A self-administration study
TLDR
It is suggested that injured bees increase their overall food intake, presumably to meet the increased energy requirements for an immune response caused by wounding, and the self-administration of morphine in response to pain. Expand
Role of food-derived opioid peptides in regulation of thermosensitivity of Periplaneta americana cockroach
TLDR
It is concluded that opioid receptors of various types are equally involved in regulation of cockroach protective behavior and the significance of phytogenous exorphines in formation of the opioid system of insects in the course of evolution is discussed. Expand
Shock-Induced Analgesia in the Cockroach (Periplaneta Americana)
For 3 consecutive days cockroaches (Periplaneta americana) received escapable, inescapable, or no shock in an escape task. 24 hr. later minimum shock which initiated movement was identified. ReliablyExpand
Complex avoidance behaviour and its neurochemical regulation in the land snail Cepaea nemoralis.
TLDR
It is concluded that endogenous opioids act antagonistic to FMRFamide in the neuronally controlled switch between passive and active avoidance behaviour. Expand
Amino acid levels during learning and memory consolidation of an aversive conditioning task in crickets
TLDR
Evidence is added for a direct involvement of these amino acids in modulating the memory consolidation process of the cricket Pteronemobius sp. Expand

The stinging response of the honeybee: Effects of morphine, naloxone and some opioid peptides
TLDR
Whereas the D50 of morphine for honeybees is far greater than that for vertebrates, the doses of naloxone that antagonize morphine are similar for bees and vertebrates. Expand
Tolerance to the morphine-influenced thermal response in the terrestrial snail, Cepea nemoralis
TLDR
The terrestrial snail, Cepea nemoralis, displayed stereotyped thermal-avoidance behavior, with morphine increasing and naloxone decreasing the latency of this response, and this behavior can serve as a useful model for the investigation of the development of opioid tolerance and physical dependence in mammals.

Opiate receptor in praying mantis: Effect of morphine and naloxone
TLDR
Results of the present paper show that the DR could be also elicited by an actual noxious (an electrical shock) and that this response is similar to that eliciting by a potential nociceptive stimulus (a patterned visual stimulus). Expand
Behavioral effects of opiates on the land snail Helix aspersa.
TLDR
The terrestrial snail Helix aspersa appears to have an endogenous opiate system involved with regulating its locomotor activities as well as its responses to tactile stimulations and the effect of morphine on locomotor activity can be considered biphasic. Expand

Analgesic activity as determined by the Nilsen method.
TLDR
The results obtained confirm the validity of the Nilsen test for the agonists and indicate its superior predictive value (to the hot-plate, Smith D′Amour, and perhaps writhing methods) for man with those substances possessing antagonist properties. Expand

TLDR
The effect of injections of selected amino acids on memory, given before a maze-learning, was investigated and a hypothesis assigning a neuromodulatory role to some amino acids is put forward. Expand

TLDR
When the components of physical dependence effect and of analgetic action have been identified with particular characteristics of the morphine molecule, it should be possible to vary them so as to produce a drug having a long and strong analgeticaction, but a short and weak dependence effect.

TLDR
A simple, rapid method for determining the pain threshold in the rat was applied to the determination of analgesic properties of several substances, including cobra venom, where no analgesic property in the latter could be demonstrated. Expand
