Abstract
Background Melatonin is responsible for regulating the sleep-wake cycle and circadian rhythms in mammals. Tramadol, a synthetic opioid analgesic, is used to manage moderate to severe pain but has a high potential for abuse and dependence. Studies have shown that melatonin could be a potential modulator to reduce tramadol addiction. Methods Male Wistar rats were used to investigate the effect of melatonin on tramadol-induced place preference. The rats were divided into four groups: control, tramadol, tramadol + melatonin (single dose), and tramadol + melatonin (repeated doses). Tramadol was administered intraperitoneally at 40 mg/kg, while melatonin was administered at 50 mg/kg for both the single dose and repeated-dose groups. The study consisted of two phases: habituation and acquisition. Results Tramadol administration produced conditioned place preference (CPP) in rats, indicating rewarding effects. However, melatonin administration blocked tramadol-induced CPP. Surprisingly, repeated doses of melatonin were ineffective and did not reduce the expression of CPP compared to that of the single dose administration. Conclusion The study suggests that melatonin may be a potential therapeutic option for treating tramadol addiction. The results indicate that melatonin attenuates the expression of tramadol-induced CPP, supporting its uses as an adjunct therapy for managing tramadol addiction. However, further studies are needed to investigate its effectiveness in humans.

Abstract
The decline in melatonin secretion with age seems to be one of the major reasons for increased sleep disruption in older animals. Previously, we showed that the administration with melatonin or its precursor, tryptophan, improved activity/rest rhythms in aged individuals. Here, it was evaluated the effect of a 10-day consumption of a Jerte Valley cherry-based nutraceutical product (patent no. ES2342141B1), which contains high levels of tryptophan, serotonin and melatonin, on the activity/rest rhythms of young and old rats (Rattus norvegicus) and ringdoves (Streptopelia risoria) as representatives of animals with nocturnal and diurnal habits, respectively, and its possible relationship with the serum levels of melatonin and glucose. Total diurnal and nocturnal activity pulses were logged at control, during, and up to 3 days after the treatment. Melatonin and glucose were measured with ELISA and testing kits respectively. In both young and old rats, the intake of the cherry nutraceutical decreased diurnal activity, whereas nocturnal activity increased. The opposite effect was observed for ringdoves. The treatment increased the circulating levels of melatonin in both species and restored the amplitude of the activity rhythm in the old animals to that of the non-treated young groups. The consumption of a Jerte Valley cherry-based nutraceutical product may help to counteract the impaired activity/rest rhythm found in aged animals.

Abstract
The purpose of the investigation was to observe the pineal-adrenal-immune system relationships and their influence on non-specific immune response in female goats under short-term thermal stress. Six female goats had been exposed to 40°C and 60% relative humidity in the psychrometric chamber for 17 days. Blood samples were obtained on days 0 and 10 to establish control and thermal stress effects, respectively. Chemical adrenalectomy was achieved by injecting metyrapone (100 mg/kg body weight) followed by exogenous melatonin treatment (0.1 mg/kg body weight) from 11th to 17th day of experiment. Thermal stress significantly (P≤0.05) altered the physiological responses. Metyrapone and melatonin treatment significantly (P≤0.05) reduced the thermal-stress-induced increase in plasma concentrations of cortisol and corticosterone while significantly (P≤0.05) increased the plasma melatonin on days 11 and 17. Furthermore, these treatments significantly (P<0.05) increased the phagocytic activity of neutrophils as compared to both control and thermal exposure values from 11-17 days of experiment. The data generated from this study help us to understand the functional relationship between pineal, adrenal, and immune system, and how this relationship modifies the non-specific immune response for the well being of goats during thermal stress.

Abstract
In the present review we summarize the relationship between the amino acid, tryptophan, the neurotransmitter, serotonin, and the indole, melatonin, with the rhythms of sleep/wake and the immune response along with the possible connections between the alterations in these rhythms due to aging and the so-called “serotonin and melatonin deficiency state.” The decrease associated with aging of the brain and circulating levels of serotonin and melatonin seemingly contributes to the alterations of both the sleep/wake cycle and the immune response that typically accompany old age. The supplemental administration of tryptophan, e.g. the inclusion of tryptophan-enriched food in the diet, might help to remediate these age-related alterations due to its capacity of raise the serotonin and melatonin levels in the brain and blood. Herein, we also summarize a set of studies related to the potential role that tryptophan, and its derived product melatonin, may play in the restoration of the aged circadian rhythms of sleep/wake and immune response, taking the ringdove (Streptopeliarisoria) as a suitable model.

Abstract
The decrease of melatonin with age contributes to immunosenescence. Its restoration via tryptophan may have immuno-enhancing effects. Therefore, we determined the effect of tryptophan administration on circulating serotonin, melatonin, cell viability, phagocytic function and levels of free radical generation of blood heterophils from old ringdoves (Streptopelia risoria), aged 11-13 years. The animals received a single oral capsule of l-tryptophan 1 hr after the onset of the light period. The tryptophan treatment significantly increased serum melatonin and serotonin levels, cell viability, phagocytosis index and phagocytosis percentage. Superoxide anion levels decreased significantly with respect to vehicle values, with the nocturnal reduction being greater than that which occurred during the light period. This suggests that orally administered tryptophan at the beginning of the day enhanced heterophil viability, phagocytic response and detoxification of superoxide anion radicals deriving from this immune function, as a result of the immunoregulatory action of melatonin and serotonin.

Abstract
Melatonin possesses chronobiotic properties, which affects sleep/wake rhythms. We investigated a 7-day administration of melatonin (0.25, 2.5 and 5 mg/kg body weight) on the activity/rest rhythms of a diurnal animal (the ringdove, Streptopelia risoria), aged 2-3 (young) and 10-12 (old) years, and its possible relationship with the serum levels of melatonin and serotonin. Total nocturnal and diurnal activity pulses were logged at basal, during, and up to 7 days after the treatments. The animals received 0.1 ml of melatonin orally 1 hr before lights off. The results showed that the administration of whichever melatonin dose decreased both diurnal and nocturnal old ringdove activity, the reduction being larger at night. The young animals also reduced their nocturnal activity with all three melatonin concentrations, whereas their diurnal activity only decreased with the 2.5 and 5 mg/kg body weight treatments. We chose those treatments that gave the best results in terms of nocturnal rest and the least affected diurnal activity (0.25 mg/kg body weight and 2.5 mg/kg in the young and old animals, respectively). Serum melatonin was measured by radioimmunoassay and serotonin by ELISA. In both age groups, the treatment increased both nocturnal and diurnal melatonin levels, with the effect continuing until 1 day after the last dose. Serum serotonin levels were unaffected by the treatments in either age group. The treatment restored the amplitude of the serum melatonin rhythm in the old animals to that of the young group. In summary, treatment with melatonin may be appropriate to improve nocturnal rest, and beneficial as a therapy for sleep disorders.

Abstract
The sleep promoting functions of melatonin have gained wide scientific attention due to the ability of this indole to provide relief from sleep inefficiency and the temporal relationship between its nocturnal rise in the blood and the "opening of the sleep gate" at night. However, little is known about the effects exerted by its precursor, the amino acid tryptophan. We studied the effect of a 7-day administration of two concentrations of tryptophan (125 and 300 kg b.w.) on the activity/rest rhythms of ringdove, aged 2-3 (young) and 10-12 (old) years, and on the serum levels of serotonin and melatonin. Activity pulses were logged before, during, and up to 5 days after the treatments. The animals received 125 or 300 mg/kg b.w. per animal/day at 09:00 h or at 19:00 h. Subsequently we chose the treatment which gave the best results in terms of nocturnal rest without affecting diurnal activity, i.e., 300 mg/kg b.w. administered to old animals at 09:00 h, 1 h after lights on, for the serotonin and melatonin measurements. During this treatment, the nocturnal and diurnal levels and amplitudes of serotonin and melatonin were all significantly higher than the corresponding levels before and after the treatment. In sum, our results point to an improvement of nocturnal rest in this animal model of old ringdove when administering 300 mg/kg tryptophan 1 h after lights on.

Abstract
The essential amino acid tryptophan is the precursor in the anabolic pathway of melatonin, a hormone with immunomodulatory properties. The present study shows the in vivo effect of tryptophan on the phagocytic function and oxidative metabolism of heterophils from Streptopelia roseogrisea of < 1 year of age, with a parallel evaluation of the plasma levels of melatonin. The L-tryptophan was administered orally (125 and 300 mg/kg b.w.) at 19:00, before the beginning of the period of darkness, for 7 days. At the end of the tryptophan treatment, determinations were made at 21:00 and 02:00 of the Phagocytosis Index, the Phagocytosis Percentage, the Phagocytic Efficiency and the superoxide anion levels in heterophils isolated from blood and of the plasma levels of melatonin. The results showed, for the determinations at 21:00 in the animals that had received 125 mg L-tryptophan/kg b.w., enhanced heterophil phagocytic function and raised levels of plasma melatonin, with no affect on the oxidative metabolism of the phagocytes. For the administration of the greater concentration of tryptophan (300 mg/kg b.w.), there were raised plasma melatonin levels together with increases in heterophil phagocytic capacity and phagocyte oxidative metabolism at 02:00. The results indicate that tryptophan administered orally at night to diurnal animals of less than 1 year in age affects the circulating levels of melatonin at the same time as inducing stimulation of the innate immune function.
