    Kunsmatige intrauteriene inseminasie met gewaste voorbereide eggenootsemen
    (Health & Medical Publishing Group, 1987-10) De Villiers, T. J.; Kruger, T. F.; Van der Merwe, J. P.; Menkveld, R.
    ENGLISH ABSTRACT: Intra-uterine insemination with washed spermatozoa of the husband was evaluated in 42 infertile couples during 103 treatment cycles. A pregnancy rate of 47.3% was obtained after an average of 2 treatment cycles in a group of patients in whom hostile cervical mucus was the only known cause of infertility. A pregnancy rate of 21.7% was obtained after an average of 2.6 treatment cycles in a group of patients in whom low sperm morphology was the only known cause of infertility. The overall conception rate of 33.3% compares favourably with that in other published series.

    Neonatal pancreatic function in infants born to mothers with gestational and overt diabetes
    (Health and Medical Publishing Group -- HMPG, 1984-11) De Villiers, T. J.; MacFarlane, C. M.; Tsakalakos, N.; Taljaard, J. J. F.
    Neonatal pancreatic function was assessed in infants born to non-diabetic mothers and to mothers with well-controlled gestational diabetes (GD) and overt diabetes (OD) using cord blood C-peptide estimations and the calculation of cord C-peptide/glucose ratios. Exaggerated pancreatic function was present in infants born to mothers with GD. In these infants the increased cord C-peptide values and cord C-peptide/glucose ratios correlated with their increased birth weight ratios. These results could not be explained on the basis of maternal hyperglycaemia and a possible intrinsic difference in pancreatic response between infants born to mothers with GD and those born to mothers with OD is suggested.
