Título: Cues to the usefulness of grooming behavior in the evaluation of anxiety in the elevated plus-maze
Fonte: Psychol. neurosci. (Impr.);5(1):105-112, Jan.-June 2012. graf, tab.
Idioma: en.
Resumo: Grooming behavior has been reported to be a response to novelty and other stressors. However, studies that sought to identify anxiety-related measures in the elevated plus-maze have not found grooming as a reliable index. Grooming has been implied with dearousal after a stressful experience. In the present work, a detailed investigation of this behavior was performed in a test with a longer duration (i.e., 10 min) than the usual duration in the elevated plus-maze. The level of anxiety was manipulated prior to the test by confining male rats to environments known to differ in the degree of aversive stimulation, including a familiar cage, a closed arm of the elevated plus-maze, and an open arm (i.e., the most aversive arm) of the elevated plus-maze. Grooming behavior was classified into three constituent elements: rostral grooming, head grooming, and body grooming. The groups were compared with regard to conventional measures of the elevated plus-maze and grooming behavior. Prior confinement to an open arm led to a delayed effect of decreased open-arm exploration undetectable during the first half of the test compared with rats previously confined to a closed arm. Prior confinement to an open arm also increased the total duration of grooming during the second half of the test. These increases were found to be partially attributable to increases in the rostral element of grooming. The percentage of interrupted bouts was also found to discriminate the group previously confined to an open arm. These results indicate that prolongation of the session can reveal effects that are otherwise undetectable and that under such conditions some grooming measures can be useful in the evaluation of anxiety-like behavior.

Resumo: This study was carried out throughout a laying period to compare the behaviour and performance of two groups of commercial layers, 180 ISA Brown and 120 Hy line W98, housed at 17 weeks of age in furnished cages with a nest box, perches, dust-bath, and claw shortening device. Based on productive parameters, the model of furnished cages studied is suitable for both, Isa Brown and Hy line hens. The study suggested that strain has a significant effect on feather condition and on some behavioural displays, particularly those related to the use of a dust-bath.

Durante um ciclo completo de postura foram avaliados o comportamento e o desempenho de duas linhagens de poedeiras comerciais, 180 ISA Brown e 120 Hy line W98, alojadas com 17 semanas de idade em gaiolas enriquecidas com ninho, poleiros, banho de areia e dispositivos de desgaste de unhas. Em ambas as linhagens, Isa Brown e Hy line W98, o modelo de gaiola estudado foi apropriado em termos de desempenho produtivo. O estudo sugeriu que a linhagem teve efeito significativo sobre a condição da plumagem e sobre alguns aspectos comportamentais, particularmente, aqueles relacionados ao uso do banho de areia.

Título: Estudio multivariado del test de bebida en campo abierto con ratas hiponutridas y desipramina com droga antipánico / Open field drink test-multivaried study with undernourished rats and desipramine as an antipanic drug

Idioma: es.
Resumo: Los modelos animales de aproximación-evitación son útiles para el estudio inicial de drogas con efecto sobre la ansiedad pero los componentes de la ansiedad valorados por estos modelos continúan pobremente definidos. Los modelos complejos de evaluación permiten inferencias más completas que aquellos que evalúan sólo una conducta. Estudios previos demuestran que el antidepresivo tricíclico desipramina ejerce un selectivo efecto anticonflicto sobre ratas adultas sometidas a un programa de privación proteica en edad perinatal, en parámetros de conducta espontánea (laberinto en cruz elevado) e ingesta condicionada (Geller-Seifter). Dichas ratas hiponutridas muestran alteraciones en la neurotransmisión noradrenérgica que se asemejan a la activación generalizada del sistema noradrenérgico que presentan los pacientes que sufren ataques de pánico. Se evaluó la actividad anticonflicto de la desipramina en una prueba de conflicto etológico: el test de bebida en campo abierto, sin descartar a priori ninguna conducta, bajo un enfoque multivariado. Este enfoque no ha sido considerado en estudios previos de campo abierto y drogas antipánico. Sobre cuatro variables seleccionadas por análisis factorial, la administración de desipramina a una dosis de 10mg/kg por sólo 7 días produjo una significativa interacción dieta × droga, consistente con estudios previos. La interacción fue independiente de los efectos de ambos tratamientos sobre el peso o la ingesta y se expresó, en las ratas hiponutridas, como un decremento en todas las conductas excepto en el tiempo de bebida con respecto a las ratas controles que mostraron, en general, un decremento en todas las conductas excepto en la frecuencia de acicalamiento.

Título: Thigmotactic responses in an open-field
Fonte: Braz. j. med. biol. res = Rev. bras. pesqui. méd. biol;41(2):135-140, Feb. 2008. ilus.
Idioma: en.
Projeto: CNPq.
Resumo: The goal of the present study was to investigate the role of thigmotaxis (the tendency to remain close to vertical surfaces) in rat exploratory behavior in an open-field. Thigmotaxis was investigated in a parametric way, using 24 experimentally adult naive male Wistar rats (210-230 g). Exploratory behavior was studied in an open-field (N = 12) in 5-min sessions and behavior was analyzed in terms of where it occurred: in areas surrounded by two, one, or no walls. Another group of rats (N = 12) was studied in an open-field with blocks placed near two of the corners so as to make these corner areas surrounded by three walls. The floor of the open-fields was divided into 20-cm squares in order to locate the exact place of occurrence of each behavior. The following behaviors were recorded: entries into the squares, rearings, and groomings. In both types of open-field the rats chose to remain longer in the squares surrounded by the largest possible number of walls. In one of the open-fields, the mean time (seconds) spent in squares surrounded by two walls was longer than the time spent in squares surrounded by one or no walls (37.2, 7.7, and 1.8 s, respectively). In the other open-field, the mean time spent in squares surrounded by three walls was longer than the time spent in squares surrounded by two, one or no walls (41.7, 20.4, 7.0, and 2.6 s, respectively). Other measures presented a similar profile. These results indicate that rats are sensitive to the number of walls in an environment and prefer to remain close to them.

Título: Evaluation of the time of uncapping and removing dead brood from cells by hygienic and non-hygienic honey bees
Fonte: Genet. mol. res. (Online);4(1):105-114, Mar. 2005.
Idioma: en.
Resumo: Most research on hygienic behavior has recorded the time taken by the colony to remove an experimental amount of dead brood, usually after one or two days. We evaluated the time that hygienic (H) and non-hygienic (NH) honey bees take to uncap and remove dead brood in observation hives after the brood was killed using the pin-killing assay. Four experimental colonies were selected as the extreme cases among 108 original colonies. Thirty brood cells were perforated with a pin in two H and two NH colonies and observations were made after 1, 2, 3, 4, 5, 6, and 24 h. Different stages of uncapping and removing were recorded. Differences in uncapping and removal between H and NH colonies were significant for all comparisons made at the different times after perforation. Using observation hives one obtains a better and faster discrimination between H and NH colonies than in full size colonies. It is possible to differentiate H and NH within a few hours after perforating the cells

Título: Reproductive experience influences grooming behavior during pregnancy in rats

Resumo: The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. Reproductive experience has epidemiologial implications such as a decrease in the incidence of mammary gland cancer in women and it also influences various behavioral, neurochemical and endocrine parameters. The aim of the present study was to investigate the influence of reproductive experience on grooming behavior patterns during pregnancy in rats. Self-grooming behavior was measured in age-matched virgin, primi- and multigravid (days 7, 8, 9, 19, and 20 of pregnancy) rats. General grooming (head, forelimbs and shoulders) was not significantly different among virgin, primi- and multigravid rats during pregnancy. Confirming previous work, pregnant rats spent significantly more time in specific grooming (mammary glands, nipple lines, genital and pelvic regions) than did virgin animals. In addition, self- licking of mammary glands was significantly increased in multi- as compared to primigravid rats on days 8, 9, 19 and 20 of pregnancy. The increase in mammary gland grooming observed in multigravid rats appears to be a consequence of previous reproductive experience. These data show that reproductive experience modulates mammary gland grooming during pregnancy, possibly contributing to successful reproduction

Título: Dopaminergic modulation of grooming behavior in virgin and pregnant rats

Resumo: Dopamine receptors are involved in the expression of grooming behavior. The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. This study focuses on the role of dopamine receptor subtypes in grooming behavior of virgin and pregnant female rats. General and mammary gland grooming were measured in virgin rats treated with 0.25 mg/kg of the D1-like agonist SKF-81297 and antagonist SKF-83566 and the D2-like agonist lisuride and antagonist sulpiride. The effects of 0.01 and 0.25 mg/kg doses of the same agonists and antagonists were evaluated in pregnant rats as well. In virgin animals both SKF-83566 and sulpiride treatments significantly reduced the time spent in general grooming, while none of the dopamine agonists was able to significantly change any parameter of general grooming. Time spent in grooming directed at the mammary glands was not affected significantly by any of the drug treatments in virgin rats. All drugs tested significantly decreased the frequency of and the time spent with general grooming, while SKF-81297 treatment alone did not significantly reduce the duration of mammary gland grooming in pregnant rats. These data show that in female rats the behavioral effects of D1-like and D2-like dopamine receptor stimulation and blockade differ according to physiological state. The results suggest that dopamine receptors may play specific roles modulating grooming behavior in pregnant rats. Since grooming of the mammary gland during pregnancy may influence lactation, this aspect is relevant for studies regarding the perinatal use of dopamine-related drugs

Resumo: Para descrever a distribuiçäo temporal diária das interaçöes de cataçäo e da autocataçäo do par reprodutor em sagüis-do-nordeste (Callithrix jacchus) ao longo do ciclo reprodutivo, dois grupos familiares foram observados no núcleo de primatologia da UFRN (Natal, RN 05§46'S 35§12'W), sob condiçöes de temperatura, iluminaçäo e umidade naturais através do método focal contínuo durante toda a fase ativa. As observaçöes comportamentais foram realizadas em dois grupos de animais. No primeiro durante duas gestaçöes e dois pós-partos näo consecutivos e no segundo ao longo do intervalo entre duas gestaçöes sucessivas, uma gestaçäo e pós-parto das fêmeas reprodutoras. A condiçäo reprodutiva das fêmeas reprodutoras e näo-reprodutoras de cada grupo foi caracterizada através da monitorizaçäo dos níveis fecais de progesterona, pelo método Elisa. Foram encontrados períodos de 24 e 8h na duraçäo da autocataçäo e das interaçöes de cataçäo social entre o par reprodutor e cada membro do grupo familiar (Cosinor, p menor ou igual 0,05). Entretanto, a periodicidade de 24h näo se apresentou estatisticamente significativa na autocataçäo e em algumas interaçöes, diante de mudanças da condiçäo reprodutiva da fêmea, associadas com a presença dos filhotes recém-nascidos após o parto e com o aumento do tamanho do grupo durante o estudo. O desaparecimento desta periodicidade após o parto pode estar relacionada a um efeito modulador do cuidado à prole recém-nascida. O par reprodutor mostrou interaçöes recorrentes com periodicidade circadiana com possíveis parceiros preferenciais, ou seja com o parceiro reprodutor e no caso do macho reprodutor, com outros filhotes machos presentes no grupo. Por outro lado, a fêmea reprodutora de um dos grupos näo mostrou esta periodicidade na cataçäo feita na fêmea adulta näo-reprodutora, quando esta passou a apresentar ciclos ovarianos. As acrofases para o período de 24h concentram-se durante a manhä, mostrando diferenças irregulares nos intervalos de confiança em algumas fases, näo permitindo identificar horários preferenciais para a interaçäo com animais específicos. Na duraçäo total diária da cataçäo feita, o par reprodutor teve preferência pelo parceiro reprodutivo, embora a fêmea apresentasse preferência pela autocataçäo ou por outros parceiros em algumas fases. A comparaçäo da autocataçäo e da cataçäo feita e recebida por cada animal em totais diários e por hora (teste Kruskall-Wallis, p menor ou igual 0,05) mostrou resultados...

Título: Thyrotropin releasing hormone injected into the nucleus accumbens septi selectively increases face grooming in rats
Fonte: Braz. j. med. biol. res = Rev. bras. pesqui. méd. biol;29(6):805-10, jun. 1996. ilus, tab.
Idioma: en.
Resumo: The effect of unilateral injection of peptides into the nucleus accumbens septi (NAS) on subcategories of grooming behavior was studied in male rats. The peptides used were: thyrotropin releasing hormone (TRH), luteinizing hormone releasing hormone (LHRH) and corticotropin releasing hormone (CRH). Male rats (Holtzman strain, 240-270 g body weight) injected with progressive doses of TRH (100, 200 and 400 ng) at 5-day intervals were compared with the control state (injection of artificial cerebrospinal fluid CSF). A selective increase in face grooming was observed with the 100 ng (49.78 + 6.11, N = 18) and 200 ng (50.29 + 7.72, N = 17) doses of TRH (P<0.05 vs CSF injection 26.94 + 3.64, N = 18). Face grooming increased further with the 400 ng dose (55.19 + 8.26, N = 16, P<0.01), but a dose-response curve could not be obtained at the dose range used. Flank scratching, head, body and genital grooming were not altered by the TRH injection, but the rearing behavior was inhibited (10.33 + 1.56; N = 18; 10.76 + 1.77, N = 17; 12 + 2.06, N = 16) (P<0.05 for all doses vs controls, 20.61 + 2.81, N = 18). The rats that received LHRH (75 ng, N = 16) and CRH (100 ng, N = 14) did not show behavioral changes when compared with their control states. The results show that injection on TRH into the NAS, but not the injection of LHRH or CRH, selectively increases face grooming without affecting other subcategories of grooming at the doses used, and appears to link this peptide with the neural substrate of stereotyped behavior.
