The long polar days of Antarctica during the summer period can disrupt the internal clock thereby desynchronizing the various bodily rhythms, which can have health implications. Hence, in the present study, in one group of six volunteers, the immunoglobulin rhythm was assessed by four hourly blood sampling. In another group of six volunteers the oral temperature rhythm was measured. The results reveal disruption of the immunoglobulin rhythm due to the influence of exogenous components and possible involvement of neuroendocrine factors. However, the oral temperature rhythm was unaffected during or after a short stay in Antarctica during the summer period. The importance of regular sleep-wake cycle and other social cues in maintaining a stable temperature rhythm is implicated. The study was conducted on two groups of volunteers, who were members of the summer team of the 14th Indian Scientific Expedition to Antarctica. In Group-I there were 6 subjects with a mean age of 35.5 ? 5.32 years. In these subjects the oral temperature rhythm was measured in three phases. In Group-II there were 6 subjects with mean age of 33.45 ? 3.48 years. Four hourly blood sampling was done on these subjects to estimate the circadian rhythm of IgG and IgM, in two phases before and after exposure to Antarctic summer. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. G Sundaresan health 20.0 140.0 -90.0 30.0 1995-01-01 1996-12-31 Earth Science-Human Dimensions Theme Maitri Antarctic Place Exposure to Antarctic Summer Affects the Immunoglobulin Rhythm but Not the Oral Temperature Rhythm Project eng TableDigital unknown unknown unknown distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncaor.gov.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF-1258240614&userType=user&freeTextValue=Exposure+to+Antarctic+Summer+Affects+the+Immunoglobulin+Rhythm+but+Not+the+Oral+Temperature+Rhythm.
