RESUMEN
A acupuntura, é uma terapia que cada vez mais adquire uma credibilidade no mundo ocidental, a sua indicação pode ser para pacientes anêmicos e imunossuprimidos, e outras afecções. O experimento foi realizado com oito cães adultos, sendo 4 fêmeas e 4 machos. O estudo consistiu em análise das concentrações das células vermelhas e brancas avaliado em 4 tratamentos: controle (T0), acupuntura (T1), eletroacupuntura unilateral (T2) e eletroacupuntura bilateral (T3). Os acupontos utilizados foram intestino grosso 4, intestino grosso 11 e estômago 36. Todos os animais passaram por todos os tratamentos com um intervalo de 7 dias para cada tratamento. Os hemogramas séricos foram verificados 20 minutos antes do início do tratamento (M0), logo após o tratamento (M1), e 60 minutos (M2) e 120 minutos (M3) após o tratamento. O resultado da série vermelha não foi significativo, mas notou-se somente uma diminuição significativa da concentração média corpuscular (CHCM) (p<0,05) no tratamento T1 no M1 em comparação aos outros tratamentos; notou-se também uma redução significativa (p<0,05) na concentração plaquetária de T1, T2 e T3 em comparação ao grupo controle. A eletroacupuntura pode levar a uma trombocitopenia, quando estimulado estes pontos, provavelmente por um estímulo parassimpaticomimético.
Acupuncture is an alternative therapy which increasingly acquires credibility in the Western Hemisphere and it is indicated for anemic and immunosuppressed patients, as well as for other diseases. The experiment was performed with 8 adult dogs, 4 females and 4 males. The study consisted to analyze the concentrations of white and red cells evaluated at four treatments: controls (T0), acupuncture (T1), unilateral electroacupuncture (T2), and bilateral electroacupuncture (T3). The acupoints utilized were: 4 large intestine, 11 small intestine and 36 stomachs. All animals experienced all treatments with an interval of 7 days to each treatment. The serum hemograms were verified 20 minutes prior to initiation to treatment (M0), at the end of the treatment (M1), 60 minutes after treatment (M2) and 120 minutes post-treatment (M3). The results revealed that the red series was not significant, but there was only a significant decrease in medium corpuscular concentration (p<0.05) at T1 of M1 as compared to the other treatments; also there was a significant reduction (p<0.05) in the platelet concentration at T1, T2 and T3 as compared to controls. The electro-acupuncture may lead to thrombocytopenia, when stimulating these points, probably by a parasympathetic stimulus.

REASON FOR PERFORMING STUDY: The development of clinical illness in foals is usually predetermined by perinatal history, management or stressful environmental conditions. OBJECTIVES: To determine potential risk factors for an increased incidence of infectious diseases during the first 30 days post partum. METHODS: The population consisted of Thoroughbred foals born on stud farms in the Newmarket (UK) area in 2005 (n = 1031). They were followed for their first 30 days. Factors suspected to influence the incidence of infectious neonatal diseases were examined in a logistic regression approach for each of the 3 outcomes (total infectious diseases, systemic disease with diarrhoea and total infectious diseases excluding diarrhoea). All 28 factors were either foal or mare or stud farm related. RESULTS: Several significant risk factors for a higher disease incidence, such as birth complications, colostrum intake by stomach tube and leucocytosis 12-48 h post partum were identified. The factor 'boarding stud' seemed to be protective against disease. CONCLUSION: Some factors, such as the mare's time at stud before foaling, the mare's rotavirus vaccination schedule and fibrinogen-values that empirically had been linked to the outcome previously were not confirmed as relevant. This included the reported useful prophylactic treatment with antimicrobial drugs. POTENTIAL RELEVANCE: Factors to be considered when evaluating newborn foals include: stud management, the birth process, route of colostrum intake, white and red blood cells, and the date of birth. These may help to detect foals at risk to develop an infection so that targeted prophylactic measures can be initiated.

Acute bracken fern toxicity in a calf was reproduced with ptaquiloside, a norsesquiterpene glucoside, isolated from the boiling water extract of bracken fern. Ptaquiloside was dissolved in 500 ml of saline and administered by drench at increasing dosages for six days out of every seven for the following periods: 400 mg/day for 24 days, 800 mg/day for 14 days and 1600 mg/day for four days. Neutrophilic granulocytes began to decrease markedly around 50 days after the start of the experiment, and granulocytopenia continued for a further 35 days until the autopsy, despite the discontinuance of ptaquiloside administration. Thrombocytes showed a relatively slow depression and reached 1 X 10(5)/mm3 at the lowest level. The calf was autopsied 86 days after the start of administration of ptaquiloside. Sternal bone marrow was found to be mostly replaced with fat marrow and only small foci of erythropoietic cells and a small number of megakaryocytes remained.
