“…Although the distal ends of the arrector pili muscle are drawn as if they adhere closely to the basement membrane beneath the layer of the skin epidermis in most literatures, it is notable that the authors of Gray’s anatomy [28] as well as some other papers [22, 23] have illustrated them in a way that shows they are not attached directly to the basement membrane. Piloerection has been used as a marker of some toxic agents [14, 25, 30, 31] or brain functions [13, 15]; however, the approaches from developmental and physiological perspectives have provided limited information. Therefore, in the present study we aimed to observe the development of the arrector pili muscle in fetal, neonatal, and adult rats by using immunohistochemical staining techniques using an antibody against SMA, one of the major components of the arrector pili muscle.…”

The hair erection muscle, arrector pili, is a kind of smooth muscle located in the mammalian dermis. The immunohistochemical study using an antibody against smooth muscle alpha actin (SMA) showed that the arrector pili muscle develops approximately 1–2 weeks after birth in dorsal and ventral skin, but thereafter they degenerate. The arrector pili muscle was not detected in the mystacial pad during any stage of development, even in the neighboring pelage-type hair follicle. A strong signal of SMA in the skin was located in the dermal sheath as well as in some outer root sheath cells in the hair and vibrissal follicles. Positive areas in the dermal and outer root sheaths were restricted to a lower moiety, particularly areas of similar height, where keratinization of the hair shaft occurs. This rule is valid for both pelage hair follicles and vibrissal follicles. At medium heights of the follicle, SMA staining in the dermal sheath was patchy and distant from the boundary between dermis and epidermis. In contrast to SMA, vimentin was expressed over the entire height of the dermal sheath. Unlike the arrector pili muscle, the expression of SMA in the dermal sheath was observed during fetal, neonatal, and adult stages. The presence of actin-myosin and vimentin fibers in supporting cells is thought to be beneficial for the hair follicle to cope with the movement of the hair shaft, which may be caused by physical contacts with outside materials or by the contraction of internal muscles.

The study aim was both to identify signs and symptoms previous to and during the pharmacological stress echocardiography test and to describe the nurse's role and nursing care principles for this exam. This is a descriptive study, carried out in cardiac care unit in a University Hospital in Porto Alegre, RS. Two hundred forty-six records of patients submitted to stress echocardiography were retrospectively reviewed, according to four different pharmacological schedules. The statistical comparison showed that signs and symptoms were related to the type of drug used during the exam, namely: typical angina, precordial ache, tiredness, headache and premature complexes. These results enabled a better understanding of pharmacological stress echocardiography and the instrumentalization of nurses in order to plan individualized and qualified nursing care assistance. Aside from helping develop nursing practices for the pharmacological stress echocardiography test this knowledge could also be used by nurses who carry out their activities in institutions that use this diagnostic method.
