Antibacterial activity of lactose-binding lectins from Bufo arenarum skin Biocell
Sánchez Riera,Alicia; Daud,Adriana; Gallo,Adriana; Genta,Susana; Aybar,Manuel; Sánchez,Sara.
Amphibians respond to microbial infection through cellular and humoral defense mechanisms such as antimicrobial protein secretion. Most humoral defense proteins are synthetized in the skin. In this study we isolated two b-galactoside-binding lectins with molecular weights of 50 and 56 KDa from the skin of Bufo arenarum. These lectins have significant hemagglutination activity against trypsinized rabbit erythrocytes, which was inhibited by galactose-containing saccharides. They are water-soluble and independent of the presence of calcium. The antimicrobial analysis for each lectin was performed. At mmolar concentration lectins show strong bacteriostatic activity against Gram negative bacteria (Escherichia coli K12 4100 and wild strains of Escherichia coli...

Assessment of an anti-ageing structured cosmetic formulation containing goji berry BJPS
Leite,Fernanda de Godoy; Oshiro Júnior,João Augusto; Chiavacci,Leila Aparecida; Chiari-Andréo,Bruna Galdorfini.
Based on previous studies, it has been found that goji berry (GB), popularly known as a ‘miracle fruit’, has excellent antioxidant potential and can be used in the treatment of skin disorders associated with ageing. This study aimed to incorporate GB into a structured cosmetic in order to optimise its penetration. Stability studies of the formulation, determination of the antioxidant activity of the extract and of the formulation, rheological measurements, SAXS, polarised light microscopy and bioadhesion analyses were performed. The results indicated the antioxidant activity of the extract, which can be incorporated into an emulsified cosmetic formulation. The emulsified formulation containing the extract remained stable, even after being submitted to...

Cambios de color en la piel del dorado (Mahi-mahi, Coryphaena hippurus) en relación a la formación de histamina OceanDocs
Wood, C.D.; Camba, N.; Grijalba, M..
En el Ecuador se utiliza el cambio de color en la piel del dorado amarillo a blanco como indicador de la calidad. Se investigó este cambio en relación a la formación de histamina bajo varias condiciones. Luego de este estudio se concluyó que, en combinación a otros parámetros como olor y textura, el color de la piel puede ser útil para distinguir pescado de buena calidad (grado A) y pescado de calidad inferior (grado B). Sin embargo existen condiciones bajo las cuales es posible tener dorado no apto para consumo humano con piel amarilla y por eso siempre es recomendable revisar todas las características sensoriales en la evaluación de calidad. Este cambio de color no hace posible la distinción entre dorado con niveles significativos de histamina. Solamente...

Chalita, Maria Carolina Catai; Matera, Julia Maria; Alves, Maria Teresa de Seixas; Longatto Filho, Adhemar.
Over the course of 17 months, non-aspiration fine needle (21-27G) cytology was performed on 213 dogs with 300 skin and soft tissue tumors. The smears were air dried and stained by the Rosenfeld method. There were 119 males (56%) and 94 females (44%), the majority of at least 6 years of age (75%). Mongrel dogs were over-represented (n=74), followed by Boxer (n=21), Poodle (n=18), German Shepard (n=15), Cocker Spaniel (n=12), and Doberman Pinscher (n= 11). In 40% of the cases (85 dogs, 117Iesions), histological evaluation was available to compare with the cytologic results. In this group, 77 specimens were benign (22 non-neoplastic and 55 neoplastic) and 40 malignant. Tumors were represented by 19%non-neoplastic lesions, 36% epithelial tumors, 30%...

Control of the skin scarring response Anais da ABC (AABC)
Ferreira,Lydia M.; Gragnani,Alfredo; Furtado,Fabianne; Hochman,Bernardo.
There comes a time when the understanding of the cutaneous healing process becomes essential due to the need for a precocious tissue repair to reduce the physical, social, and psychological morbidity. Advances in the knowledge on the control of interaction among cells, matrix and growth factors will provide more information on the Regenerative Medicine, an emerging area of research in medical bioengineering. However, considering the dynamism and complexity of the cutaneous healing response, it is fundamental to understand the control mechanism exerted by the interaction and synergism of both systems, cutaneous nervous and central nervous, via hypothalamus hypophysis-adrenal axis, a relevant subject, but hardly ever explored. The present study reviews the...

Dermatosparaxis in two White Doper lambs in Brazil: case report Arq. Bras. Med. Vet. Zootec.
Silva,A.P.C.; Mol,J.P.S.; Carvalho Junior,C.A.; Paixão,T.A.; Santos,R.L..
Dermatosparaxis is a genetic disease that affects collagen maturation. This disease is characterized by marked impairment of the resistance of collagen fibers that leads to skin fragility, and it may affect several species. This is the first report of dermatosparaxis in sheep in Brazil. Clinically, two White Dorper lambs had multiple skin lacerations in the neck, dorsum and limbs. Transmission microscopy demonstrated irregular collagen fibers arranged in hieroglyphic shape and scanning electron microscopy demonstrated thin collagen fibrils that were not arranged in bundles as observed in the normal dermis. These findings are consistent with the diagnosis of dermatosparaxis.

Mahmood,Tariq; Akhtar,Naveed; Khan,Barkat Ali; Rasul,Akhtar; Khan,Haji M. Shoaib.
Complex multiple emulsions have an excellent ability to fill large volumes of functional cosmetic agents. This study was aimed to encapsulate large volume of green tea in classical multiple emulsion and to compare its stability with a multiple emulsion without green tea extract. Multiple emulsions were developed using Cetyl dimethicone copolyol as lipophilic emulsifier and classic polysorbate-80 as hydrophilic emulsifier. Multiple emulsions were evaluated for various physicochemical aspects like conductivity, pH, microscopic analysis, rheology and these characteristics were followed for a period of 30 days in different storage conditions. In vitro and in vivo skin protection tests were also performed for both kinds of multiple emulsions i.e. with active...

Immunohistochemical and Histopathological Changes in the Skin of Rats after Administration of Lead Acetate International Journal of Morphology
Sula,Bilal; Deveci,Engin; Özevren,Hüseyin; Ekinci,Cenap; Elbey,Bilal.
Lead acetate is a chemical compound. Sources of human exposure to this metal include many foods, drinking water and dust. The aim of this study was to determine the immunohistochemical and histopathological changes on the face skin after lead acetate application. Wistar Albino rats (180-200 g body weight) were divided into a controlled and lead acetate-exposed group. Rats received lead acetate at 500 ppm in their drinking water for 60 days. Both groups were fed with the same standard food, but lead acetate was added to the drinking water. During the experimental period, blood samples were drawn from the abdominal aorta of the anesthetised animals. At the end of exposure, body weight and blood lead levels were measured. Sections of rat facial skin were...
