The experiment was carried out to show the influence of endogenous and added insulin in sows colostrum on insulinaemia and glycaemia of newborn piglets. In colostrum collected from 3 control and 5 experimental sows before loading, basal insulin concentration were 1.595 and 1.365 nM-1, respectively, and calculated for all 8 sows together were 1.451 nM-1 (SEM +/- 0.289). Basal plasma insulin concentrations calculated for 68 healthy piglets before sucking were little differentiated (mean 0.318 +/- 0.044 nM l-1), whereas glucose initial concentrations for those piglets (mean 3.581 +/- 0.275 nM l-1) were highly differentiated. Intramuscular loading of 5 experimental sows with insulin (80 I.U. per animal) caused an increase in the concentration of insulin in colostrum from 1.365 to 3.449 nM l-1 (0.01, P less than 0.02). The mean insulin level (0.313 +/- 0.04 nM l-1) in experimental piglets blood plasma (n = 42) increased significantly to 1.234 +/- 0.07 (P less than 0.001) after suckling by sows loaded with exogenous insulin. Glycaemic response of those two piglets litters was poor but showed a statistically significant increase (P less than 0.001). The glucose concentrations in blood plasma samples of the other three litters did not changes after sucking. The experiment excluded the hypothesis that high level of insulin in colostrum could be the cause of hypoglycaemia in healthy piglets after sucking.</p>","PeriodicalId":7158,"journal":{"name":"Acta physiologica Polonica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13290872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Importance of dynamics of sweating in men during exercise.","authors":"R Grucza,&nbsp;O Hänninen","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Influence of dynamics of sweating on rectal temperature increase was tested in 3 groups of men performing cycle exercise with intensity of 65, 90 and 120 W, respectively, in 22 degrees C chamber temperature and 30% of relative air humidity. During exercise at 65 and 90 W the subjects wore suits while exercising with intensity of 120 W they wore only shorts. The dynamics of sweating was described by delay in onset of sweating and time constant of the reaction. Wearing caused significant increase in skin humidity and decreased evaporative rate of sweating. Sweat rate during steady state was related to the metabolic rate in naked (r = 0.89, p less than 0.002) as well as in wearing subjects (r = 0.93, p less than 0.01). Delay in onset of sweating was, in average, 5 min with a time constant of 7 min. Both factors showed a tendency to be shorter with increasing work intensity. Mean increase in rectal temperature was proportional to the intensity of exercise although the individual delta Tre correlated well with the dynamics of sweating in naked (r = 0.83, p less than 0.01) and wearing subjects (r = 0.84, p less than 0.01). Since delta Tre was smaller in subjects with shorter inertia time of sweating in response to beginning of exercise at the same intensity it is concluded that the dynamics of sweating can play an important role in limiting body temperature increase in working men.</p>","PeriodicalId":7158,"journal":{"name":"Acta physiologica Polonica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13290764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
