The diets affected the weight of the liver and content of protein in the liver and LM. The protein:DNA ratio was lowest on high carbohydrate (HC) and commercial (C) diets in both tissues and about 3 times higher in LM than in the liver. The RNA:protein ratio was highest in the high protein-fat (HPF) and recommended (R) diet fed groups. The RNA:DNA ratio was lowest on HC and C diets. In the liver, PSCatD, AAA, LIA were lowest on HPF, and highest on HC diets, but for PIA on high fat-protein (HFP) and C diets, respectively. The highest activities were correlated with the lowest percentage of protein and fat in the diets (low energy diets). For LM, the highest activities were found on a C diet and lowest for PSCatD on HEP but for AAA, PIA, LIA on HC diets. Cathepsin D accounted for about 70% of hemoglobin degradation in the liver and 66% in LM. In AAA, cathepsin D participates in 58.5% and 50.5% in the liver and LM inhibition, respectively, but leupeptin accounted for about 15% and 27% (in the presence of Mg++) of inhibition.</p>","PeriodicalId":7158,"journal":{"name":"Acta physiologica Polonica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1989-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13630159","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}
