Under normal conditions the rat papillary muscle exhibits a negative force-frequency dependence which differs from ventricular preparations in many other mammals. Caffeine (10 mmol/l) introduced into the bath solution abolishes a negative force-frequency dependence in the papillary muscle of rat. During incubation of the rat ventricular preparations in the caffeine-containing solution the force-frequency relations measured on these muscles display the same behaviour as in guinea pig preparations. Caffeine has induced no changes in the force-frequency relations of guinea-pig ventricular preparations. A conclusion is made that caffeine-sensitive intracellular calcium stores participate in species-determined differences in force-frequency relations of the ventricular muscles.</p>","PeriodicalId":12337,"journal":{"name":"Fiziologicheskiĭ zhurnal","volume":"39 4","pages":"97-100"},"PeriodicalIF":0.0,"publicationDate":"1993-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19233289","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}

In contrast to the human colostrum, the bovine colostrum exerted a suppressive effect on proliferation of mouse splenocytes and Ig synthesis induced by suboptimal doses of LPS. Bovine casein did not significantly affect the Ig synthesis by mouse splenocytes. Suppression of the Ig synthesis was associated with bovine colostral globulins.

Filling of the gallbladder under artificial sequestration of bile acids during duodenal probing, enterosorption and cholatogenic diarrhea was studied in 55 patients with cholecystitis.
