Abstract A cohort study of 90 days was designed to explore the hypercholesterolemic associated blood pressure with intake of extruded flaxseed powder (EFSP) fortified yogurts. The hypercholesterolemic subjects were distributed into two groups (1 and 2), then blood samples and blood pressure were taken. Descriptive statistics were used for comparison between groups. A significant increase in serum total cholesterol (TC) (6.330.48 to 6.510.04 mmol/dL) and low-density lipids-cholesterol (LDL-C) (5.170.28 to 5.370.47 mmol/dL) was observed in participants consuming plain milk yogurts for 30 days. A significant decrease in TC (6.470.95 to 6.28 ± 0.84) and LDL-C (5.350.29 to 5.130.44 mmol/dL) was observed in the group consuming EFSP fortified sheep milk yogurt. Similarly, a significant decrease in serum TC (6.381.01 to 6.200.98 mmol/dL), and LDL-C (5.301.16 to 4.980.99 mmol/dL) was noticed in the group consuming EFSP fortified cow milk yogurt. The intake of fortified yogurts reduced significantly serum cholesterol associated with blood pressure in both groups.

RESUMO O objetivo primário desse estudo foi comparar a farmacocinética de florfenicol (FFL) em fluido epitelial pulmonar à farmacocinética (PK) de FFL em plasma suíno. O segundo objetivo foi avaliar o efeito de anestesia com ketamina e propofol no PK de FFL em plasma. Lavagem broncoalveolar foi utilizada para quantificar volume de fluido epitelial pulmonar (PELF) e método de diluição de uréia para determinar FFL em PELF. Injeção de FFL foi administrada intramuscular a suínos em dose única de 20mg/kg de peso corporal. Os principais parâmetros de PK em FFL em plasma e PELF foram os seguintes: a área sob a curva de concentração-tempo, concentração máxima da droga, eliminação de meia-vida e média de tempo de permanência foram 69,45±4,36 vs 85,03±9,26μg·hr/ml, 4,65±0,34 vs 5,94±0,86μg/ml, 9,87±1,70 vs 10,69±1,60hr e 12,75±0,35 vs 14,46±1,26hr, respectivamente. Não houve diferença estatisticamente significante entre os perfis de PK de FFL para os porcos anestesiados e não anestesiados. Esse estudo sugere que (i) FFL penetrou rapidamente no pulmão e concentração da droga sofre queda mais veloz em plasma que líquido pulmonar, (ii) o perfil de PK de FFL em suínos não modificou após administração de agente anestésico.

ABSTRACT The primary objective of the current study was to compare the pharmacokinetic (PK) of florfenicol (FFL) in pulmonary epithelial lining fluid and the plasma in swine. The second objectives were to evaluate the effect of anesthesia with ketamine and propofol on the PK of FFL in plasma. Bronchoaveolar lavage was utilized for quantification of PELF volume and the urea dilution method was used to determine the concentration of FFL in PELF. FFL was administered intramuscularly (IM) to swine in a single dose of 20mg/kg body weight. The main PK parameters of FFL in plasma and PELF were as follows: the area under the concentration-time curve, maximal drug concentration, elimination half-life and mean residence time were 69.45±4.36 vs 85.03±9.26μg·hr/ml, 4.65±0.34 vs 5.94±0.86μg/ml, 9.87±1.70 vs 10.69±1.60hr and 12.75±0.35 vs 14.46±1.26hr, respectively. There was no statistically significant difference between the PK profiles of FFL for the anesthetized and unanesthetized pigs. This study suggest that (i) FFL penetrated rapidly into the pulmonary and the drug concentration decay faster in plasma than in the pulmonary, (ii) the PK profile of FFL in swine was not interfered after administration of anesthetic agent.
