Haematological and biochemical parameters in Churra-da-Terra-Quente ewes from the northeast of Portugal / Parâmetros hematológicos e bioquímicos de ovelhas da raça Churra da Terra Quente do nordeste de Portugal

Hematological and biochemical parameters, including plasma electrolytes and thyroid hormones, were determined in 73 clinically healthy Churra-da-Terra-Quente ewes, a typical breed from the northeast of Portugal. The hemogram values were: erythrocytes 9.8±1.5×10(12)/L; haemoglobin 118.1±19.1g/L; haematocrit 40.8±5.9 percent; leukocytes 5.7±1.8×10(9)/L; and platelets 544.3±177.2×10(9)/L. The thrombin time was 17.3±1.7 seconds. The values of biochemical parameters were: total protein 76.4±6.1g/L; glucose 2.87±0.60mmol/L; total cholesterol 1.65±0.33mmol/L; aspartate aminotransferase 155.9±49.2U/L; alanine aminotransferase 23.2±9.6U/L; γ-glutamyl transferase 48.0±18.7U/L; total alkaline phosphatase 121.6±76.1U/L; glutamate dehydrogenase 6.4±3.7U/L; urea 7.32±2.22mmol/L; creatinine 123.0±54.1μmol/L; total calcium 2.53±0.25mmol/L; phosphorus 2.10±0.46mmol/L; magnesium 1.01±0.09mmol/L; sodium 152.04±3.65mmol/L; potassium 4.7±0.4mmol/L; ionized calcium 1.32±0.07mmol/L; total thyroxine 111.75±42.29nmol/L; total triiodothyronine 1.01±0.28nmol/L; free T4 11.93±1.78pmol/L; free T3 4.22±1.33pmol/L; and thyroid-stimulating hormone 0.18±0.19μIU/mL. Although differences among the Churra-da-Terra-Quente breed and other breeds may occur, the hematological and biochemical parameters, plasma electrolytes, and thyroid hormones, for this indigenous breed, were generally situated within the reference intervals previously reported for sheep.

Os valores hematológicos e bioquímicos, incluindo os eletrólitos plasmáticos e os hormônios da tireoide, foram determinados em 73 ovelhas, clinicamente saudáveis, da raça Churra da Terra Quente, raça ovina característica do nordeste de Portugal. Os valores obtidos para o hemograma foram: eritrócitos 9,8±1,5×10(12) /L; hemoglobina 118,1±19,1g/L; hematócrito 40,8±5,9 por cento; leucócitos 5,7±1,8×10(9) /L e plaquetas 544,3±177,2×10(9)/L. O tempo de trombina foi de 17,3±1,7 segundos. Os valores dos parâmetros bioquímicos avaliados foram: proteínas totais 76,4±6,1g/L; glicose 2,87±0,60mmol/L; colesterol total 1,65±0,33mmol/L; aspartato amino transferase 155,9±49,2U/L; alanina amino transferase 23,2±9,6U/L; gama-glutamil transferase 48,0±18,7U/L; fosfatase alcalina total 121,6±76,1U/L; glutamato desidrogenase 6,4±3,7U/L; ureia 7,32±2,22mmol/L; creatinina 123,0±54,1μmol/L; cálcio total 2,53±0,25mmol/L; fósforo 2,10±0,46mmol/L e magnésio 1,01±0,09mmol/L; sódio 152,04±3,65mmol/L; potássio 4,7±0,4mmol/L e cálcio ionizado 1,32±0,07mmol/L; tiroxina total 111,75±42,29nmol/L; tri-iodotironina total 1,01±0,28nmol/L; T4 livre 11,93±1,78pmol/L; T3 livre 4,22±1,33pmol/L e hormônio estimulante da tireoide 0,18±0,19μIU/mL. Apesar de terem sido observadas algumas diferenças entre a raça Churra da Terra Quente e outras raças, os valores hematológicos e bioquímicos, eletrólitos plasmáticos e hormônios da tireóide, desta raça autóctone apresentam-se no geral situados dentro dos intervalos de referência publicados para a espécie ovina.

Tumoral DNA analysis by flow cytometry in patients submitted to esophagectomy for squamous cell carcinoma of the esophagus

Squamous cell carcinoma of the esophagus has a poor prognosis. There are several factors influencing the prognosis. The study of DNA ploidy by flow cytometry used in many malignant tumors is very valuable in determining, as a tumor marker, this prognosis. In this study 13 cases of resected squamous cell carcinoma of the esophagus were analyzed. Despite the small sample, the authors observed that the worst prognosis was in advanced stage cases (III and IV), an aneuploid DNA pattern. The only case with a 5-year survival had a diploid DNA pattern.

Gastric metastasis of melanoma

We present a case of gastric metastasis, leading to chronic bleeding in a patient already submitted to surgery for a malignant melanoma of the lip. In view of the good clinical conditions, a subtotal gastrectomy as palliative treatment was performed. We discuss the diagnostic and therapeutic aspects of this rare clinical situation
