Important changes take place in the cortical cytoplasm of human oocytes in connection with their maturation. Contacts between granulosa cell processes and the oocyte are interrupted, the perivitelline space develops, invaded by oocyte long microvilli. Fine flocculent material is deposited in the perivitelline space. As for oocyte cell organelles, changes(More)
The average digestibility coefficients of feed mixture nutrients in pigs infected medium severely to severely by the helminths Ascaris suum and Oesophagostomum dentatum were lower in comparison with the post-dehelminthization condition (dry matter by 3.1%, crude protein by 6.7%, fat by 8.9%, nitrogen-free extracts and fibre by 2.2%, organic matter by 3.1%).(More)
Fracture of an ankylosed spine is often overlooked. Because the force that damages an ankylosed spine is frequently slight, patients do not realize they are injured. Doctors can miss the fracture for the same reason and because patients already have a history of back pain. Plain radiographs sometimes fail to demonstrate the fracture site.
Ruptured abdominal aortic aneurysm (AAA) remains to be represent a common and highly lethal problem. We reviewed the records of 92 patients (73 men and 19 women) operated on for ruptured infrarenal AAA within the past 10 years (January 1989 to October 1999) in the 2nd Department of Surgery in Brno, Czech Republic. The mean age was 71 years (range 57 to 92(More)
A simple and highly efficient percutaneous method eliminating the spinal ganglion and its posterior spinal cord root in treating metameric pain is described. Monitored by X-ray the needle crosses the vertebral canal passing e.g. from the right into the left intervertebral space. The intervention itself is made by a mesocaine alcohol block. The first(More)
The human two-cell ovum consists of two equally sized blastomeres, surrounded by the zona pellucida. Cumulus cells may be apposed to the exterior of the zona. The blastomere nuclei contain spherical nucleoli, made up of fibrillar matrix, and randomly dispersed chromatin. The cytoplasmic structures include mitochondria, smooth endoplasmic reticulum, annulate(More)
