Última Behavioral effects of endogenous or exogenous estradiol and progesterone on cocaine sensitization in female rats BJMBR Souza,M.F.; Couto-Pereira,N.S.; Freese,L.; Costa,P.A.; Caletti,G.; Bisognin,K.M.; Nin,M.S.; Gomez,R.; Barros,H.M.T.. Cocaine sensitization is a marker for some facets of addiction, is greater in female rats, and may be influenced by their sex hormones. We compared the modulatory effects of endogenous or exogenous estradiol and progesterone on cocaine-induced behavioral sensitization in 106 female rats. Ovariectomized female rats received progesterone (0.5 mg/mL), estradiol (0.05 mg/mL), progesterone plus estradiol, or the oil vehicle. Sham-operated control females received oil. Control and acute subgroups received injections of saline, while the repeated group received cocaine (15 mg/kg, ip) for 8 days. After 10 days, the acute and repeated groups received a challenge dose of cocaine, after which locomotion and stereotypy were monitored. The estrous cycle phase was...

Toxins incl. Trop. Dis. Costa,VM; Langoni,H. The milk of experimentally infected rats was investigated for the presence and possible transmission of Toxoplasma gondii. Wistar (Rattus norvegicus) female rats were divided into three groups and orally inoculated with bradyzoites. Polymerase chain reaction (PCR) was employed to detect the parasite in the milk. Transmission to the offspring was verified by indirect immunofluorescence antibody test (IFAT), modified agglutination test (MAT), bioassay tests and PCR. Rat milk samples were PCR-positive, pups were serum-reactive to T. gondii and tissue samples also presented positive DNA results through PCR.

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1678-91992010000200016 Influence of lactation on motor activity and elevated plus maze behavior BJMBR Lactating rats show less noise-induced freezing and fewer inhibitory responses on the 6th day post-delivery when submitted to water and food deprivation in a classical conflict paradigm. Lactating mice go more often to the illuminated chamber in a light-dark cage and stay longer in it than virgin females. The present study was designed to assess the influence of this physiological state, i.e. lactation, on the elevated plus maze (EPM) and open-field behavior in adult female rats. Total (TL) and central (CL) locomotion and rearing (RF) frequencies were measured in an open-field. Number of entries into the open and closed arms as well as the time spent in each of these arms were measured in the EPM. Percent time spent and number of entries into the open arms...

Ano: 1997 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X1997000200013 Parasympathetic dysfunction is associated with insulin resistance in fructose-fed female rats BJMBR Brito,J.O.; Ponciano,K.; Figueroa,D.; Bernardes,N.; Sanches,Í.C.; Irigoyen,M.C.; De Angelis,K.. The objective of the present study was to identify metabolic, cardiovascular and autonomic changes induced by fructose overload administered in the drinking water of rats for 8 weeks. Female Wistar rats (200-220 g) were divided into 2 groups: control (N = 8) and fructose-fed rats (N = 5; 100 mg/L fructose in drinking water for 8 weeks). The autonomic control of heart rate was evaluated by pharmacological blockade using atropine (3 mg/kg) and propranolol (4 mg/kg). The animals were submitted to an intravenous insulin tolerance test (ITT) and to blood glucose measurement. The fructose overload induced a significant increase in body weight (~10%) and in fasting glycemia (~28%). The rate constant of glucose disappearance (KITT) during ITT was lower in...
