“…O efeito estimulador da serotonina (5-HT), na maturação ovariana, tem sido demonstrado para outras espécies de crustáceos, a exemplo de Uca pugilator (Richardson et al, 1991) e Procambarus clarkii Kuljarni & Fingerman, 1992;Sarojini et al, 1995b).…”

“…Entretanto, a literatura tem registrado o estímulo da serotonina na liberação de diversos hormônios, tais como o hormônio hiperglicemiante (Keller & Bayer, 1968), o hormônio dispersante do pigmento vermelho (Rao & Fingerman, 1970), o hormônio neurodepressor (Arechiga et al, 1985) e o hormônio inibidor da muda (Mattson & Spaziani, 1985). Investigando o papel da serotonina na indução da maturação ovariana em Uca pugilator, Richardson et al (1991) aventam o papel indireto da serotonina para estimular a liberação do hormônio estimulador da gônada, o que foi confirmado posteriormente pelas investigações de para Procambarus clarkii in vivo e por Sarojini et al (1995b) in vitro nesta mesma espécie. Richardson et al (1991), utilizando substâncias bloqueadoras de 5-HT, confirmaram sua ação endógena no desenvolvimento ovariano.…”

“…Ainda em relação à serotonina, Richardson et al (1991) observaram, em Uca pugilator, que o efeito da serotonina é dose-dependente, registrando ser esta uma característica típica de sistema regulado por hormônio. Para U. pugilator foi registrado o estímulo indutor da serotonina sobre a maturação ovariana, em doses iguais ou superiores a 1,25 x 10 -8 mol/animal.…”

Evaluation of the effect of serotonin (5-HT) and eyestalk monoablation on the induction of ovary maturation in Penaeus Penicillatus (Alcock, 1905)The effects of serotonin and of the monoablation of eyestalk on the induction of gonadal development of Penaeus penicillatus (red tail shrimp) were investigated. Immature females with an average weight of 20 g were selected and ramdonly distributed into four groups of 5 animals as follows: initial control group (IC), sacrificed at the 1 st day of the experiment; parallel control group (CG), injected with 0.05 ml of saline solution; monoablated group (AG), submitted to monoablation at day 0 and injected with 0.05ml of saline immediatelly after the monoablation and on the 5 th day; serotonin group (SG), injected with 0.05 ml of serotonin, dissolved in saline solution, both on day 0 on the 5 th day, in a total dose of 15 µg per gram of animal's weight (7,74 x 10 -7 mol). Animals were sacrificed on day 0 for the initial control group (IC), and on the 5 th , 10 th and 15 th days for the other groups. A fragment from the front lobe of the animal's gonad was fixed in aqueous Bouin and processed with the usual optic microscopy techniques. Analyses consisted of a morphological description of cells and measurements of the diameter of oocytes, which gave evidence to the stimulating role of serotonin and of monoablation on gonad maturation. The statistical analysis (Anova -SNK, P < 0.05) of the diameter values of oocytes showed monoablation to be more effective in inducing ovary maturation than serotonin at the concentration used (7,74 x 10 -7 mol).Key words: Penaeus sp., serotonin, 5-HT, reproduction, ovary maturation. RESUMOO efeito da serotonina e da monoablação do pedúnculo ocular na indução do desenvolvimento gonadal de Penaeus penicillatus (camarão do rabo vermelho) foi investigado. Fêmeas imaturas com peso médio de 20 g foram selecionadas e distribuídas de maneira aleatória em quatro grupos de 5 animais com uma réplica para cada grupo: grupo controle inicial (CI), sacrificado no 1 o dia do experimento; grupo controle paralelo (GC), injetado com 0,05 ml de solução salina; grupo monoablado (GA), submetido à monoablação no dia 0 e injetado com 0,05 ml de solução salina logo após a monoablação e no 5 o dia; grupo serotonina (GS), injetado com 0,05 ml de serotonina dissolvida em solução salina no dia 0 e 5 o dia, numa dose total de 15 µg por grama de peso do animal (7,74 x 10 -7 mol). Os animais do grupo controle inicial (CI) foram sacrificados no dia 0, e no 5 o , 10 o e 15 o dias para os demais grupos, respectivamente. Fragmentos dos lóbulos anteriores das gônadas dos animais foram fixados em Bouin

Dopamine in crayfish and other crustaceans: Distribution in the central nervous system and physiological functions

Dopamine is widely distributed in the crustacean nervous system and has a diverse array of physiological effects. Immunocytochemical studies of several species have shown that dopamine- and/or tyrosine hydroxylase-containing cells occur in all ganglia of the central nervous system and that processes from some of these cells link ganglia of the ventral nerve cord. This study describes the distribution of tyrosine hydroxylase-containing cells in the central nervous system of a crayfish (Orconectes rusticus) and compares this information to available data from other species. The distribution of tyrosine hydroxylase (an enzyme in the synthetic pathway between tyrosine and dopamine) in O. rusticus is similar to that reported for marine species. However, differences were observed in the number of neurons in some ganglia and in the axonal projections of the L cell, which were more extensive in O. rusticus than in other species studied thus far. We also review the physiological effects of dopamine in crayfish and other crustaceans, focusing on the amine's actions in the endocrine, cardiovascular, and nervous systems, and on behavior when injected into freely-moving animals.

Several investigators suggest a relationship between neurotransmitters, serotonin (also called 5-hydroxytryptamine, 5-HT), and dopamine (DA) in the regulation of growth and reproductive development of vertebrate species, rather than the invertebrate species. In this study, we evaluated the role of 5-HT and DA in reproductive development of an invertebrate species, the freshwater crab Barytelphusa guerini. We tested the effects of 5-HT both alone and combined, and also the effects of an opioid antagonist naloxone, on reproductive development of B. guerini in terms of testicular and ovarian developmental parameters. Injection of either 5-HT or naloxone alone significantly increased the ovarian index and the oocyte diameter in female crabs, and the testicular index and testicular follicular diameter in male crabs. In contrast, injection of DA inhibited all the reproductive measures in both sexes. Co-injection of 5-HT with DA exhibited no significant effects on the reproductive development in both sexes compared to the control treatments. These results suggest that 5-HT, DA, and exogenous naloxone may be involved in the regulation of gonad stimulating hormone (GSH) and/or gonad inhibiting hormone (GIH). These results also provide evidence that naloxone may regulate endogenous neurotransmitters and its downstream hormones, GSH and GIH.
