To determine if exercise affects gastric endocrine function the following experiment was performed. Four horses were fed total mixed ration of ground corn and chopped hay at 2% of their body weight, divided into 2 equal portions, daily. Horses were fasted overnight, and serum gastrin concentration was determined just before and 2 hours after feeding. The horses were then sprint trained on a high speed treadmill for 6 weeks. The response of serum gastrin to feeding was then repeated as before. Serum gastrin increased following feeding both before and after training, however the postfeeding gastrin value was higher [p = 0.035] after training (68.1 +/- 6.9 pg/ml [mean +/- 1 SEM]) than before (42.7 +/- 3.8 pg/ml). These data show that treadmill exercise has an effect upon the gastric hormonal response to a meal in the horse. The relationship of this finding to the development of gastric ulcer disease is unknown at present, but warrants further investigation.</p>","PeriodicalId":22466,"journal":{"name":"The Cornell veterinarian","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19300782","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}

Viral reactivation of CHV, without clinical signs, was induced twice in 2/3 adults and in 2/3 pups treated at intervals that ranged from 1 to 3 months following the initial infections.

The duration of viral shedding after the second series of steroid treatments also was shorter than the shedding period following the initial reactivations.
