Usefulness of sperm penetration assay in fertility predictions
The competence of the sperm penetration assay (SPA) to predict male fertility, as determined by normal sperm morphology and the fertilizing potential, as shown by human in vitro fertilization (IVF), was investigated. A ...
A quick, reliable staining technique for human sperm morphology.
The evaluation of sperm morphology is still an important parameter in the diagnosis of the infertile male. Most techniques used for staining human sperm are very time-consuming. A routine stain used for determining ...
Analysis of vitamin B6 vitamers in human tissue by cation-exchange high-performance liquid chromatography
This publication reports the modification of existing methodology to analyse vitamin B6 vitamers in human erythrocytes, mononuclear cells (MNCs) and human liver biopsy tissue. It further reports for the first time a complete ...
Clinically solitary thyroid nodule
In the 7 years from June 1973 to May 1980 we found 281 solitary nodules among the 1 528 patients presenting with thyroid abnormalities at the Thyroid Clinic of the Tygerberg Hospital. Of these, 89.3% occurred in females. ...
Morphologic changes observed in experimental cryptorchidism
[No abstract available]
Breed differences in plasma calcium, phosphorus and magnesium concentrations of Merino, Dohne Merino and S.A. Mutton Merino sheep with relation to the bent-leg syndrome.
Plasma calcium, phosphorus and magnesium concentrations were determined in ewes and their single and twin lambs from birth for 120 days in Merino, Dohne Merino and South African Mutton Merino sheep. Mineral concentrations ...
The influence of experimentally induced copper deficiency on the fertility of rams. I. Semen parameters and peripheral plasma androgen concentration.
The influence of molybdenum and molybdenum plus sulphate-induced copper deficiencies on semen quality and peripheral plasma testosterone concentrations in South African Mutton Merino rams was investigated. All animals ...
The influence of experimentally induced copper deficiency on the fertility of rams. II. Macro- and microscopic changes in the testes.
The macro- and microscopic changes of the testes caused by molybdenum as well as a molybdenum plus sulphate induced copper deficiency were investigated in S.A. Mutton Merino rams. Judged on testes measurements, the testes ...
Extraperitoneal aortofemoral bypass
An extraperitoneal exposure of the infra-renal aorta is described. This exposure differs slightly from that described by Rob and others in that the inferior epigastric artery is not sacrificed during the exposure. 47 ...
Effect of ethanol on [3H]dopamine release on rat nucleus accumbens and striatal slices
Ethanol (10-200 mM) transiently increased tritium overflow from superfused rat nucleus accumbens slices previously incubated with [3H]dopamine (DA) and [14C]choline. The effect was greater in striatal tissue and did not ...
