Investigations were made of the action of ACTH and LH-RH on a number of behavioural paradigms and the possible involvement of neurotransmitters or opiates by pretreatment of receptor blockers in rats and mice. ACTH delayed the extinction of active avoidance behaviour. Atropine and haloperidol blocked this action, whereas phenoxybenzamine and propranolol were ineffective. LH-RH or a highly potent analogue of LH-RH (D-Trp6-LH-RH) decreased the rate of disappearance of dopamine in the hypothalamus following alpha-methyl- paratyrosine inhibition of catecholamine synthesis, and blocked the accumulation of serotonin following MAO inhibition. LH-RH or the analogue attenuated the consolidation of passive avoidance learning. Apomorphine-induced cage-climbing was also inhibited by the LH-RH analogue, but this action was not influenced by naloxone. Open-field activity (ambulation, rearing and grooming) was decreased by the analogue peptide. Naloxone blocked the action on ambulation and rearing, but was ineffective on grooming. The LH-RH analogue caused a dose-dependent increase in cataleptogenic activity. This action could not be blocked with naloxone. The LH-RH analogue suppressed picrotoxin-induced seizures. Naloxone restored the situation to the control level. The data suggested that the effects of some neurohormones are mediated by transmitters or endogenous opiates, and that both peptide-transmitter and peptide-peptide interactions have to be considered in the action of neurohormones.

We evaluated the effects of various intravenously administered drugs, which had been shown to influence bladder function in anesthetized and/or conscious rats, on the cystometrogram in conscious restrained-denervated rats (produced by transection of the hypogastric nerve) placed in a restraining cage in comparison to those in conscious restrained-intact rats (with the hypogastric nerve intact) placed in a restraining cage. The bladder capacity in the restrained-denervated rats was smaller than that in restrained-intact rats and did not change when they were transferred to a wide cage, but the bladder capacity of the restrained-intact rats decreased following transfer to the wide cage. Therefore, the activity of the hypogastric nerve in conscious rats appears to be stimulated by restraint. Atropine suppressed the amplitude of the micturition contraction (time to micturition in the cystometrogram). In the restrained-denervated rats, thiopental and indomethacin increased the bladder capacity at almost the same doses as those in restrained-intact rats, but it took a higher dose of morphine to increase the bladder capacity than in restrained-intact rats. These findings suggest that cystometrography in restrained-denervated rats is a useful method for evaluating the effect of a newly developed agent on bladder function without any influence from the hypogastric nerve.

1. Juvenile male rats treated with parachlorophenylalanine showed hair loss round the head and neck extending down the chest and abdomen.2. Treated isolated rats did not have this loss of hair, while untreated animals living in the same cage as treated rats lost their hair. The loss therefore seems to be caused by increased social behaviour. This consists of a greater frequency of chasing each other, rolling over and social grooming.3. Adult male rats show an increase in mounting after treatment with parachlorophenylalanine, and this change in behaviour was counteracted by treatment with 5-hydroxytryptophan.4. It is concluded that 5-hydroxytryptamine inhibits sexual behaviour in male rats. The increase in social interaction seen in juvenile rats may be the behavioural precursor of adult sexual behaviour.5. Atropine 2.5 mg/kg blocked all forms of social interaction in adult male rats, although other activity was not altered.

1. Male albino mice were watched in red light on a tunnel board to test exploration and their motor activity was assessed in an open cage, 30 min after intraperitoneal injection of drugs.2. Atropine and methylatropine 5 or 10 mg/kg did not alter the motor activity of the mice, while chlordiazepoxide 25 or 50 mg/kg and diazepam 10 or 20 mg/kg increased the activity, especially at the lower of the two doses used.3. All the compounds used except methylatropine adversely affected the exploratory behaviour.4. When atropine 10 mg/kg was given with the benzodiazepines, the activity of the mice was reduced and exploratory behaviour was further impaired. Methylatropine did not have this effect.

We studied the involvement of the cholinergic system in the contralateral head-eye-body turning induced in the cat through stimulation of the pulvinar-lateralis posterior nucleus complex (P-LP). In 17 cats through a cannula aimed at the P-LP, agonists and antagonists of the cholinergic system were injected. The electrical activity of the P-LP could be recorded through the same cannula or through electrodes attached to it. In addition, electrodes were implanted ipsilaterally in the dorsal hippocampus, caudate nucleus, amygdala, and superior colliculus to record through them and through one screw placed on the skull the electrical activity of those structures and of the cortical P-LP projection. Seven days after surgery, carbachol, an agonist of the cholinergic system was injected in the P-LP, and the behavior and electrical activity of the unrestrained cat (previously accustomed to a plastic cage) were recorded. A control volume of 0.9% NaCl was always injected previously. The usual drug volume injected was 1 microliter; occasionally, 2 microliter were injected. Weekly or biweekly sessions were conducted to determine (a) the threshold for cholinergic activation, (b) the threshold for turning behavior, (c) the blocking effect of local atropine sulfate injected previously, (d) the effect of haloperidol previously injected (locally or systemically), and (e) the effect of dioxolane, an exclusive muscarinic agonist. In 14 of 17 cats, contralateral turning behavior was evoked by carbachol. In two of the three cats that did not respond to carbachol, dioxolane induced turning. The effect of dioxolane was similar to that of carbachol when tried in five cats. Besides turning behavior, carbachol produced numerous symptoms due to cholinergic activation. Atropine blocked the rotational effect of carbachol in all cats, and haloperidol blocked it in 68% of them. Electrolytic coagulation of the dorsal hippocampus surrounding the P-LP did not disturb the effects induced by carbachol. These experiments show that both systems of the P-LP, cholinergic and catecholaminergic, are involved in the contralateral turning. We conclude that the effect induced by carbachol is due to activation of muscarinic receptors because it is totally blocked by local atropine sulfate and is reproduced by dioxolane, an exclusive muscarinic agonist.

Acetylcholine potently stimulates the hypothalamic-pituitary-adrenal (HPA) axis. Cholinergic receptor agonist carbachol, given intraperitoneally (i.p.) or into the lateral cerebral ventricle (i.c.v.) to non-anesthetized rats acts via multiple pathways to stimulate the HPA axis. The present study sought to determine 1) the functional selectivity of carbachol for cholinergic muscarinic and/or nicotinic receptors involved in the stimulation of HPA axis; 2) the involvement of prostaglandins (PGs) generated by constitutive and inducible cyclooxygenase (COX-1 and COX-2) in the carbachol-induced ACTH and corticosterone secretion in non-stressed rats and animals exposed to social crowding stress for 7 days (24 per a cage for 6). Carbachol was given i.c.v. or i.p. and cholinergic receptor antagonists or cyclooxygenase isoenzyme antagonists were given by the same routes 15 min earlier. One hour after the last injection trunk blood was taken for ACTH and corticosterone determinations. Atropine (0.1 microg i.c.v.), a cholinergic receptor antagonist, totally abolished the carbachol (2 microg i.c.v.)-induced ACTH and corticosterone secretion and mecamylamine (20 microg i.c.v.), a selective nicotinic receptor antagonist, did not affect this secretion. This finding indicates that carbachol functions as a selective central cholinergic muscarinic receptor agonist for the HPA axis stimulation. Crowding stress significantly diminished the carbachol (0.2 mg/kg i.p.)-induced plasma ACTH and corticosterone levels measured 1 hr after administration. Pretreatment with indomethacin (2 mg/kg i.p.), a non-selective cyclooxygenase inhibitor, significantly diminished the ACTH and corticosterone responses to carbachol (0.2 mg/kg i.p.) in control rats and moderately decreased these responses in stressed rats. Piroxicam (0.2 and 2.0 mg/kg i.p.), a COX-1 inhibitor, considerably impaired the carbachol-induced ACTH and corticosterone responses in control rats and markedly diminished these responses in stressed rats. A selective COX-2 blocker, compound NS-398 (0.2 and 2.0 mg/kg i.p.), substantially decreased the carbachol-induced hormones secretion in control rats but did not markedly alter this secretion in stressed rats. These results indicate that in the carbachol-induced HPA axis activation PGs generated by COX-1 are considerably and to a much greater extent involved than PGs generated by COX-2. Social stress markedly diminishes the mediation of PGs generated by COX-1 but PGs synthesized by COX-2 do not substantially participate in the carbachol-induced HPA response.
