Objective: The aim of the present study is to evaluate the effect of a 12 weeks hippotherapy intervention protocol on hip adductors spasticity in children with spastic cerebral palsy., Design: Randomized controlled trial., Settings/location: The intervention was conducted in an Equestrian and Therapeutic Association. Patients were recruited from a Rehabilitation Unit of Cerebral Palsy., Subjects: A total of 44 children with spastic cerebral palsy (Gross Motor Function Classification System [GMFCS] levels IV-V; 28 boys and 16 girls; aged 8 years 10 months, SD 3 months) were assigned to a treatment (n = 22; mean age 9 years 6 months, SD 3 months) or a control group (n = 22; mean age 8 years 3 months, SD 3 months)., Interventions: The control group received conventional therapy, and the treatment group received hippotherapy in addition to their conventional treatment. The intervention consisted of a 12-weeks hippotherapy program (1 time/week, 45 min)., Outcome Measures: Both groups were assessed before and after the full program with the Modified Ashworth Scale (MAS)., Results: There were significant differences in the MAS scores between the treatment and the control group in both adductors (left adductors: p = 0,040; right adductors: p = 0,047), after a 12-weeks hippotherapy intervention., Conclusions: A hippotherapy based treatment in addition to conventional therapy, in children with cerebral palsy, produces statistically significant changes in hip adductors spasticity after a 12-weeks intervention. Thus, it seems to produce benefits in the short-term., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

The present article reports the effect on survival as well as morpho-histochemical changes in the gills of juvenile turbot Scophthalmus maximus L., induced by acute action of the anionic surfactant sodium dodecyl sulfate (SDS). First, LC(50) at 96 h was found to be 7.5 mg/L of SDS. Second, lots with 20 individuals were exposed to SDS concentrations of 3, 5, 7, and 10 mg/L in order to obtain the exposure time required for 50% mortality of the specimens (384, 190, 12, and 4 h) and surface tension values (60.2, 56, 54.9, and 53.3 mN/m), respectively. Finally, histopathological lesions (clubbing and fusion of the secondary lamellae, hyperplasia and posterior rupture of the respiratory epithelium, destruction and shortening of gill filaments, and the presence of hemorrhagic foci) and histochemical alterations in the distribution of carbohydrates and proteins in the gills of treated specimens were noted. These morpho-histochemical changes in the gills provoked functional disorders (i.e. asphyxia and the loss of osmotic and ionic regulation) that may ultimately play an important role in the mortality of turbots exposed to SDS., ((c) 2002 Elsevier Science (USA).)
