Plasma biochemistry values in wild female hawksbill turtle (Eretmochelys imbricata) during nesting in Mexican coast / Valores de bioquímica plasmática em tartaruga de pente (Eretmochelys imbricata) durante a época de desova na costa mexicana

To obtain plasma biochemistry values, blood was collected for 47 nesting females of apparently healthy Eretmochelys imbricata sea turtles using sodium heparin as an anticoagulant. Blood samples were collected in April-Jun for two years (nesting season). Hematologic characteristics, including packed cell volume, white blood cell counts, red blood cell count and hemoglobin level; and plasma chemistry values, including creatinine, blood urea nitrogen, uric acid, triglyceride, total cholesterol, and glucose were measured. The data generated from this study may be useful for clinical assessment of health and disease of wild hawksbill sea turtles on nearshore habitats in the Gulf of Mexico, thus contributing to a conservation of this species.(AU)

Para obter valores da bioquímica plasmática, foram coletadas amostras de sangue durante a desova de 47 tartarugas marinhas fêmeas aparentemente saudáveis da espécie Eretmochelys imbricata, utilizando heparina sódica como anticoagulante. Amostras de sangue foram coletadas durante dois anos entre os meses de abril e junho (época de nidificação). Mediu-se os parâmetros hematológicos (incluindo hematócrito, contagem de glóbulos brancos e vermelhos e nível de hemoglobina) e os valores da bioquímica plasmática (incluindo creatinina, ureia, ácido úrico, triglicérides, colesterol total e glicose). Os dados gerados a partir deste estudo podem ser úteis para a avaliação clínica de saúde e de doença em tartarugas-de-pente em habitats próximos ao litoral no Golfo do México, contribuindo para a conservação dessa espécie.(AU)

Relationship between endothelin and nitric oxide in plasma with retinopathy in the pregnancy-induced hypertension / 中华眼底病杂志

Objective To explore the effect of endothelin (ET)、nitric oxide (NO) in plasma on retinopathy in the pregnancy-induced hypertension (PIH). Methods The level of ET and NO in plasma of 75 cases of in-patient women with PIH and 20 cases of women with the full terms and normal pregnancy before and after delivery was determined by radioimmunoassay. The retinopathy of the patients with PIH before and after delivery was detected by appointed doctor. The levels of ET and NO in both groups were compared and the relationship between ET and NO in plasma and the retinopathy before and after the delivery was detected. Results The levels of ET [(145.00?54.41) ng/L] in serious PIH patients were much higher than that in the control [(81.50?43.80) ng/L], the minor [(85.30?33.33) ng/L] and middling PIH group [(90.20?39.25) ng/L]. The levels of ET in plasma before and after pregnancy were not changed in PIH patients [(118.70?33.44) ng/L], but were higher than that in the control group. The levels of plasma NO in serious [(87.56?35.58) ng/L] and middling [(78.11?28.96) ng/L] PIH group were both higher than that in the control group [(46.70?32.64) ng/L], and the levels in minor[(52.56?28.35) ng/L] and middling PIH group were lower than that in the serious PIH group. The level of NO in plasma of PIH patients after the delivery was much lower than that before the delivery, while higher than that in the control. The positive correlation between levels of ET and NO and retinopathy was found in PIH patients. Conclusions The levels of plasma ET and NO in PIH patients are related to the extent of the disease, and the level of ET in plasma is highly related to the retinopathy in PIH patients. ET and NO might be played an important role in pathogenesis of retinopathy and ET might be a good index in reflecting the rank of retinopathy in PIH.
