The dorsal raphe nucleus exerts opposed control on generalized anxiety and panic-related defensive responses in rats

It has been proposed that the ascending dorsal raphe (DR)-serotonergic (5-HT) pathway facilitates conditioned avoidance responses to potential or distal threat, while the DR-periventricular 5-HT pathway inhibits unconditioned flight reactions to proximal danger. Dysfunction on these pathways would be, respectively, related to generalized anxiety (GAD) and panic disorder (PD). To investigate this hypothesis, we microinjected into the rat DR the benzodiazepine inverse receptor agonist FG 7142, the 5-HT1A receptor agonist 8-OH-DPAT or the GABA(A) receptor agonist muscimol. Animals were evaluated in the elevated T-maze (ETM) and light/dark transition test. These models generate defensive responses that have been related to GAD and PD. Experiments were also conducted in the ETM 14 days after the selective lesion of DR serotonergic neurons by 5,7-dihydroxytriptamine (DHT). In all cases, rats were pre-exposed to one of the open arms of the ETM 1 day before testing. The results showed that FG 7142 facilitated inhibitory avoidance, an anxiogenic effect, while impairing one-way escape, an anxiolytic effect. 8-OH-DPAT, muscimol, and 5,7-DHT-induced lesions acted in the opposite direction, impairing inhibitory avoidance while facilitating one-way escape from the open arm. In the light/dark transition, 8-OH-DPAT and muscimol increased the time spent in the lighted compartment, an anxiolytic effect. The data supports the view that distinct DR-5-HT pathways regulate neural mechanisms underlying GAD and PD. (C) 2002 Elsevier B.V. B.V. All rights reserved.

Oocysts of Hepatozoon canis in Rhipicephalus (Boophilus) microplus collected from a naturally infected dog

Canine hepatozoonosis is a tick-borne disease caused by protozoans of the genus Hepatozoon. Several tick species have been implicated as potential vectors. Therefore, extensive studies are needed to determine the 'natural' endemic cycle of this parasite. This paper presents the first report of the presence of Hepatozoon canis oocysts in Rhipicephalus (Boophilus) microplus collected from an infected dog. (C) 2011 Elsevier B.V. All rights reserved.

Análise de dez anos de utilização de serviços de saúde por uma coorte de pacientes diagnosticados com hipertensão arterial, no CSE - Botucatu, em 1995

The arterial hypertension is a chronic disease, which can be controlled by changing the way of life, as well as by drug treatment, which demand specific Health Care sequence. The lack of adherence to sequence/treatment is one of the main obstacles the disease control. Characterize and analyze the profile of Health Care usage by a 192 patient cohort diagnosed with arterial hypertension in 1995, between the period of 2001 – 2005 and 2006 – 2010. It is a longitudinal study, retrospective and descriptive developed on School Health Center(SHC) which belongs to School of Medicine Botucatu –UNESP, in continuity of the previous research which has analyzed the sequence of the referred sample between the period of 1995 – 1999. The database was obtained from the patients records by using structured adapted forms appointed in the previous study phase. In the case there were transfers to other Health Care facilities, the database was obtained by the records either, while the patients attended the CSE. The database was analyzed by means of descriptive statistics. Predominated the patients in the age from 50 – 69 (47,9%), whites (93,2%), female (56,7%) with low level of education (72,7%). In the period of 2001 - 2005, 76 (39,5%) of the patients remained under sequence, and that 44 (22,9%) belonged to adherence group (GAD), 17 belonged to abandonment/adherent group (GAB/GAD) and 15 to the abandonment group (GAB), groups which were already identified by the study which has analyzed the period of 1995 – 1999. At the end of the third period of the sample sequence (2006 – 2010), 60 (31,2%) of the patients kept under medical sequence. The cohort’s mortality rate in the period reached 15,1% and 21,9% were transferred to other Municipal Health Care facilities. We conclude that the Health Care service usage by the 192 sample’s integrants kept the same model already identified in the previous analysis... (Complete abstract click electronic access below)
