A v. capsularis was found in 35 regions (58.3%), usually as a single vein. There were 1-3 vv. suprarenales (but mostly two; on the right they usually joined the v. cava caudalis and on the left the v. renalis sinistra). A v. spermatica was present on the right side in every case, but on the left side in 11 cases only; in one case it was duplicated. In the rat, the v. spermatica was rather thin; if absent, it was replaced by the v. deferentialis. In nine cases (60.0%) the v. uterina cranialis dextra opened into the v. cava caudalis, while in 12 cases (80.0%) the left vein opened into the v. renalis sinistra. A v. uterina media, draining blood from the caudal third of the cornu uteri, was found in only five cases (16.7%). The v. uterina caudalis drained blood from the corpus and cervix uteri. The v. ovarica was a constant finding; it was mostly joined by the v. lumbalis--and on the left side by the v. phrenica sinistra. In males, the vv. lumbales occurred mostly as a pair of veins lying just below the vv. renales. In females, they were present on both sides. As a rule, the v. iliolumbalis occurred as a single vein on both sides. The v. cava caudalis originated at the level of the transition between the lumbar and the sacral spine, usually at the confluence of the two vv. iliacae communes, which in 14 cases (46.7%) were joined by the v. sacralis mediana. Duplication of the v. cava caudalis was found in only one case (a female). Comparison of the morphology of the v. cava caudalis and its tributaries in the rat and the guinea pig showed more slight differences between the two species.","PeriodicalId":12562,"journal":{"name":"Functional and developmental morphology","volume":"2 2","pages":"89-98"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12620230","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":"The importance of prenatal period to the new-borns population quality.","authors":"J Dejmek","doi":"","DOIUrl":"","url":null,"abstract":"Approximately 60% of all human pregnancies terminate spontaneously before birth, mostly before being recognized. Exceptionally high prevalence of abnormalities has been found in this reproduction output. Original frequency of chromosomal (ChA) and developmental anomalies (DA) is not known, but may be very high. From 100 spontaneously aborted fetuses about 50 are ChA, approximately 70 are DA and only about 20 are without any pathological finding. Using data on ChA and DA distribution in newborns and those in abortuses--together with the knowledge on abortion rates in various gestation phases--the prenatal population structure may be reconstructed: in the pregnancy recognition phase about 7% ChA and 10-15% DA conceptuses remain in the population of surviving fetuses. Prenatal selection decreases gradually the frequency of anomalies to the values that are usually found in new-borns. The disappearance of particular anomalies is nonrandom, changing the malformation spectrum continually. The risk of prenatal elimination of the anomaly is not invariably proportional to the degree of phenotype damage of the fetus. Study of the hidden part of prenatal population offers the possibility to cover a considerably larger fraction of the whole reproduction output and supplies new valuable knowledge.","PeriodicalId":12562,"journal":{"name":"Functional and developmental morphology","volume":"2 3","pages":"187-99"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12659201","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}
