The mammary souffle of pregnancy and lactation.
IN 1908 van den Bergh' described a loud systolic murmur of unusual quality that appeared in a woman the day after parturition. It was localized to a small area in the second right intercostal space, and disappeared entirely when firm pressure with the stethoscope bell was applied over the site of maximum intensity. He believed the murmur was extracardiae, and owed its origin to enlarged tortuou...
متن کاملUltrasonographic Examination of Mammary Glands in Caspian Mares during the Lactation and Dry Period
Objective- The aim of this study was to determine the normal ultrasonographic and morphologic appearance of mammary gland and teat in Caspian mares during lactation and dry period. Design- Experimental study. Animals- Seven mature Caspian mares Procedures- Using a 6.5-8.5 MHz linear transducer the ultrasonographic appearance of lactating and dry mammary glands was determined in 7 mature Casp...
متن کاملLactation Biology Symposium: Mammary gland biology revisited
The mammary gland goes through a coordinated series of developmental states during postnatal life in preparation for lactation. These changes ultimately reflect a changing endocrine environment alongside local alterations in the microenvironment. A longstanding assumption has been that estrogens serve as the first essential component for any of these developmental changes to be realized in the ...
متن کاملLactation Biology Symposium: effects of photoperiod on mammary gland development and lactation.
Photoperiod, or the daily sequence of light and dark, has dramatic effects on many physiological systems across animal species. Light patterns alter melatonin secretion profiles and, subsequently, the release profiles and circulating concentrations of several hormones that influence a variety of physiological responses. Although the impact of photoperiod on reproductive processes is perhaps the...
متن کاملBovine Mammary Gene Expression Profiling during the Onset of Lactation
BACKGROUND Lactogenesis includes two stages. Stage I begins a few weeks before parturition. Stage II is initiated around the time of parturition and extends for several days afterwards. METHODOLOGY/PRINCIPAL FINDINGS To better understand the molecular events underlying these changes, genome-wide gene expression profiling was conducted using digital gene expression (DGE) on bovine mammary tiss...
