Antioxidant defence of colostrum and milk in consecutive lactations in sows
<p>Abstract</p> <p>Background</p> <p>Parturition is supposed to be related to oxidative stress, not only for the mother, but also for the newborn. Moreover, it is not clear whether consecutive pregnancies, parturitions, and lactations are similar to each other in regards to intensity of metabolic processes or differ from each other. The aim of the study was to compare dynamic changes of antioxidative parameters in colostrum and milk of sows taken during 72 h postpartum from animals in consecutive lactations. Activities of glutathione peroxidase (GSH-Px), glutathione transferase (GSH-Tr), and superoxide dismutase (SOD), and amount of vitamin A and C were measured. Healthy pregnant animals were divided into 4 groups according to the assessed lactation: A -1<sup>st </sup>lactation (n = 10), B - 2<sup>nd </sup>and 3<sup>rd </sup>lactation (n = 7), C - 4<sup>th </sup>and 5<sup>th </sup>lactation (n = 11), D - 6<sup>th </sup>- 8<sup>th </sup>lactation (n = 8). The colostrum was sampled immediately after parturition and after 6, 12, 18 and 36 h while the milk was assessed at 72 h after parturition. Spectrophotometric methods were used for measurements.</p> <p>Results</p> <p>The activity of antioxidative enzymes and the concentration of vitamin A increased with time postpartum. The concentration of vitamin C was the highest between the 18th and 36th h postpartum.</p> <p>Conclusions</p> <p>Dynamic changes in the values of antioxidant parameters measured during the study showed that sows milk provides the highest concentration of antioxidants in the 2<sup>nd </sup>and 3<sup>rd </sup>and 4<sup>th </sup>and 5<sup>th </sup>lactation giving the best defence against reactive oxygen species to newborns and mammary glands.</p

Digital image analysis of fingernail colour in cadavers comparing carbon monoxide poisoning to controls
The original publication is available at www.springerlink.comCarbon monoxide is a component of motor vehicle exhaust fumes, provided a functional catalytic converter is not present. This gas binds avidly to the hemoglobin molecule in red blood cells preventing its oxygen transport function, effectively poisoning the body by starving it of oxygen. In binding to hemoglobin, carbon monoxide forms carboxyhemoglobin, which has a characteristic bright pink color. It has been remarked that the fingernails of victims of carbon monoxide tend to exhibit pink color, otherwise fingernails of deceased bodies tend towards a dark red to blue color. This study sought to objectively determine by using digital image analysis if a color difference occurred between the fingernails of a group of cadavers with carbon monoxide poisoning compared to a group of controls. The fingernails of the carbon monoxide group did tend to be more red than the controls, but due to overlap between the two groups assessment of the fingernails cannot be recommended as a rapid screening test.Neil E.
