RESUMO

This work describes a malformation in one newborn female bovine, with two faces and two skull fused, showing one single head. Duplications of the nasal and oral structures, tetraofthalmy, two brains, one single cerebellum, and pons were observed. The right thyroid was hypertrophic and the other organs had normal morphology. Every change observed in this case was compatibles with diprosopus.(AU)

RESUMO

This study aimed to evaluate the effects of the homeopathic complex Homeopatila RS (REAL Homeopathy, Brazil), in the performance, sexual proportion and gills and liver histology of the Nile tilapia fish (Oreochromis niloticus L.). 4,800 post-larvae were treated for 45 days, in 12 tanks (500 L), in a closed environment, with density of 400 larvae per tank. Three treatments were given: alcohol 30%, negative control (C); hormonal, positive control, 17 alpha-methyltestosterone (H); homeopathic, Homeopatila RS, in ethanol (HH), with four replications. Mean values for length, weight, liver somatic index, condition factor, survival rate, average values of histological alterations and sexual proportion were determined. Analysis revealed significant differences (p<0.05) in growth, survival rate, liver somatic index and average values of hepatic histological alterations between treatments. It was concluded that the addition of Homeopatila RS to the diet of Nile tilapias, during the phase of gonadal differentiation, did not induce any alteration in the sexual proportion. Homeopathically treated fish were significantly smaller, but had significantly greater survival than the other two groups, there was no significant difference in final total biomass. The homeopathically treated fish had a lower liver/somatic index with less hepatic lipid inclusions than the other groups.

RESUMO

Two outbreaks of Amaranthus retroflexus (redroot pigweed) poisoning occurring in cattle in southern Brazil in late summer and early autumn are described. In both instances too many cattle were held in small paddocks heavily invaded by A retroflexus in its seeding stage. In 1 herd 8/28 heifers and in the other 15/45 adult cows died. Clinical courses ranged from 3 to 7 d. Clinical signs included depression, loss of weight, mild serous nasal discharge, foul smelling liquid feces tinged with blood, subcutaneous dependent edema, and laborious and incoordinated walking. Main necropsy findings were subcutaneous, cavitary and perirenal edemas, renal subcapsular hematomas, and ulcerative lesions in the alimentary tract. The kidneys were swollen and pale. Histopathological findings were in the kidneys and consisted of tubular degeneration, necrosis and regeneration with interstitial fibrosis and tubular proteinosis.

RESUMO

Lipoprotein(a) (Lp(a)) is one of the most important independent risk factors for the prediction of premature atherosclerosis. Lp(a) is a low-density lipoprotein (LDL)-like particle which contains a glycoprotein (apoprotein(a)) disulfide linked to apo B-100. We describe a sandwich ELISA based on an anti-apo(a) monoclonal antibody (MAb) and an anti-apo B MAb for the quantitative determination of Lp(a) in human serum. The assay is sensitive, precise and specific. Samples with different apo(a) isoforms had a linear response in a range of 3-70 mg/dl of Lp(a). Correlations between the ELISA and a commercial ELISA, an immunoradiometric assay and electroimmunodiffusion were 0.92, 0.96 and 0.98, respectively. The frequency distribution of Lp(a) concentration in blood donors showed the skew toward the right reported in other populations. Patients with angiographically assessed coronary atherosclerosis had three times higher levels of Lp(a) than those with no signs of coronary atherosclerosis.

RESUMO

Se describe la producción de anticuerpos monoclonales (AcMs) de ratón contra la apolipoproteína A1 (APO A1), a partir de la inmunización de ratones BALB/c con APO A1 purificada de plasma humano. Los anticuerpos obtenidos son de la clase IgG1 y fueron purificados a partir de líquido ascítico mediante cromatografía de afinidad con Proteína A Sepharosa. Dos de ellos, que reconocen sitios diferentes de la molécula de APO A1 en muestras de suero. Los coeficientes de variación intra e interensayo fueron de 3,4 y 10 % respectivamente. Con este sistema se detectaron niveles disminuídos de APO A1 en pacientes con infarto agudo del miocardio entre 45 y 80 años, y en grupo con aterosclerosis periférica entre 40 y 49 años, con relación a sujetos controles de igual rango de edad. En los pacientes con aterosclerosis periférica de mayor edad (entre 60 y 80 años), aunque se encontraron valores de APO A1 más bajos que el grupo control respectivo, esta diferencia no fue estadísticamente significativa
