{"title":"[Morphology and development of bovine testicular vein (V. testicularis) during the prenatal and neonatal periods].","authors":"P Wyrost, J Radek, T Radek","doi":"","DOIUrl":"","url":null,"abstract":"Investigation into the morphology and development of the testicular vein in bovine was carried out with 85 male foetuses from the 8-40th week of pregnancy and with 10 newborns aged 1 to 10 days of life, the total being 95 preparations. The age of the foetuses was determined by Kantorova method complemented with those by other authors. The observations were made with using rubber latex introduced into the lumen of the tested veins by means of an automatic device of our own construction. It was found out that the developmental transformations of the testicular veins, initiated in the embryo, progress very dynamically in foetuses up to about the 20th week of pregnancy and them gradually slow down in older foetuses. Finally, in a fully formed testicular vein of the oldest foetuses and newborns there can be distinguished the proximal and distal part of this vessel. The proximal part carries the blood away from labile components of the testicular vein, the only exceptions being the aortic branch and the ureteral vein. Now, the solid components escape into the distal part of testicular vein. In the course of the distal part of the vessel there are its three basic plexuses, i.e. the testicular plexus, the marginal plexus of testicular vein and the largest of them--the pampiniform plexus of testicular vein. The blood from the last plexus is carried away into the main trunk of testicular vein by two anastomotic branches--lateral and medial. Of the veins examined the right one usually escapes to the caudal vena cava or to the deep circumflex iliac vein, while the left one to deep circumflex iliac vein or to the common iliac vein.","PeriodicalId":20364,"journal":{"name":"Polskie archiwum weterynaryjne","volume":"30 3-4","pages":"17-38"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13286902","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 purpose of the experiment was to estimate the effect of beta-carotene and apo-beta-carotenoic acid (10% Carophyll yellow) on some indices of cellular immunity in chicks receiving the feed of high vitamin A content. Chl and NBT proved that carotenoids increased phagocytic activity of neutrophiles in peripheral blood. Similarly, in the case of beta-carotene it was found by blastic transformation test that on 30-40th day of the experiment, the value IS of peripheral blood lymphocytes was increased. On the other hand, chicks fed apo-beta-carotenoic acid showed such an effect on 40th day of observation only in the case when the lowest dose of preparation (24 mg/kg of feed) and Con A as mitogen were applied. In each experimental group, the chicks exhibited increased flavin content in liver and markedly increased retinol content due to apo-beta-carotenoic acid (24 mg/kg of feed). On the other hand, the contents of alpha tocopherol and ascorbic acid did not show significant differences between experimental and control groups. Similar were the results with iron, zinc and magnesium. Copper content of the liver was markedly increased in the birds receiving apo-beta-carotenoic acid in the dose of 24 mg/kg of feed. The increased content of manganese was observed in the liver of birds receiving beta carotene (6 mg/kg of feed).","PeriodicalId":20364,"journal":{"name":"Polskie archiwum weterynaryjne","volume":"30 1-2","pages":"117-26"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13287772","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}
