By injecting intravenously a bolus of Xe-133 during breathholding and by recording the influx of activity into the lung with a scintillation camera and analogue tape storage, the regional perfusion of the lungs can be determined, using the count-rate increase per unit time. Once the maximum count-rate is reached the patient is allowed to breathe normally. The slope of the count-rate decrease over the lungs is a measure of ventilation. The regional ventilation/perfusion ratio is calculated by dividing these two indices. Regional disturbances of the ratio are the most frequent cause of hypoxia. The demonstration of such disturbances are therefore of significance in the diagnosis and therapeutic control of pulmonary diseases.</p>","PeriodicalId":19324,"journal":{"name":"Nuclear-Medizin","volume":"14 3","pages":"232-9"},"PeriodicalIF":0.0,"publicationDate":"1975-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12384939","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}

The distribution patterns of the radioactivity in the mother animal and in the fetus resp. in the sucklings are investigated at different intervals post inj. within a range of 10 to 120 minutes for the pregnant and at 8 hours after last injection for the lactating animals. With regard to its metabolic properties it is still admissible to identify the recorded radioactivity with the intact pharmaceutical to large extent for the intervals used in the experiments. The compound is distributed rapidly within the maternal organism and is excreted preferentially by the liver. Compared to blood level a considerable 14C-enrichment is obvious in the brain during the total time of investigation, which seem to be of special interest for the clinical use of the diazepam. An organotropism to the ovary is indicated by the patterns of radioactivity. A rapid diaplacental passage can also be shown, but the 14C-concentrations in blood and organ tissues of the fetus are generally found to be lower than those of the maternal organ tissues. Thus, the 14C-concentration in the fetal brain is equal to 1/3 of that of the maternal brain. Due to the mammoglandular passage the 14C-concentrations in the sucklings are reaching a maximum of one half of the values in the maternal organs.</p>","PeriodicalId":19324,"journal":{"name":"Nuclear-Medizin","volume":"14 3","pages":"272-84"},"PeriodicalIF":0.0,"publicationDate":"1975-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12384942","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}
