Origem do plexo lombossacral e seus nervos em quatis (Nasua nasua, LINNAEUS, 1766)

The objective of this research is to study the origin of the lumbosacral plexus and its nerves in coatis (Nasua nasua). Six adult specimens, three males and three females, were used in this research. The animals were donated by IBAMA / GO or were collected when found dead by the edges of highways in Southeast Goiás. The specimens were fixed in aqueous 10% formaldehyde solution and preserved in the same solution. The observations reveal that the lumbosacral plexus of the coati has a structure with few intercommunications between its components. There are no typical handle formations, but the roots or its branches converge to form the nerves that are driven to the pelvic limb. The components of the Lumbosacral Plexus are ventral branches of L4 to S3. The Lumbosacral plexus generates several short nerves destined to pelvic structures and, at the same time, three long nerves: femoral, obturator and sciatic, all destined to the hind limb.

Desenvolvimento de um exoesqueleto para movimentação/reabilita-ção de paraplégicos

People bedridden by paralysis/motor disability are subject to several problems due to lack of movement. Then, it is necessary to use equipments that enable the people bedridden stand up and walk, so as to reduce the problems due to lack of movement and the time of rehabilitation, impacting directly on its quality of life. The aim of this work is the development of an exoskeleton to make the movement of people with paralysis / motor impairment in the lower limbs, without help of third parties, to be activated by the user. To provide support, stability and security to the deficient, it was decided to use a structure formed by four legs, being each leg consisting of a parallel chain. The gait was obtained by combining the movement of two mechanisms: crank/rocker, responsible for oscillatory motion of the leg, and cam/follower, responsible for the foot motion on the desired trajectory. To achieve the aim of this work was conducted a study about the types of exoskeletons for locomotion/rehabilitation of people with lower limb paralysis and presented a study on the movement of the lower limb joints. It also presented a mathematical model to obtain the desired path to the foot of the exoskeleton, the static model and the design of the structure elements. In the sequence is presented the simulation of movements of a people during the human gait, experimental tests and the comparison with the human gait developed by a people without disabilities.

Internação involuntária e o abuso de substâncias psicoativas - o pathos familiar

The use and abuse of Psychoactive Substances (PAS) in contemporaneity corresponds to a social issue and a public health issue. Few social phenomena entail more costs with justice and health, family difficulties, and appearances in the media than the PAS abuse comsumption. The government power has been facing this situation allocating investments and developing public policies. Despite the current Mental Health Policy, based on the principles of Psychiatric Reform that prioritizes outpatient services, the number of investments from various government spheres and families requests for admissions continue increasing. This study aimed to understand the pathos experienced by an individual toward the involuntary internment of a family member who is an abusive user of PAS. The research also aimed to investigate what led that individual to choose this type of treatment. The Psychoanalysis was the theoretical basis of this work, and the exercise of the psychoanalytic method, from the collection of bibliographic references up to the interpretation of the semi-structured interview, conducted in depth, was intended. The findings of this research gave us the oportunity of thinking about how the social callings to the family were made, especially in regard of atention and care with their family members who are user of PAS and how it affects this family individual. It also allowed to discuss how the public policies that preconize involuntary internment, affectivity, prohibitionist and mono-disciplinarity – that cross the State in the attention given to this issue – are formulated and implemented. The interview analysis showed us how happen the agencying of pathos, the libidinal aspects of joy and guilt, the desire to punish and atonement, working in family relations and in caring relations, especially in the decision for involuntary internment. The survey also made possible to understand how a mother, facing the chaotic scene of public health, helpless, finds in the involuntary internment a way to reverberate her affections.
