Kallikrein promotes the release of kinins, which have been shown in in vitro studies to improve motility, viability and metabolism in human spermatozoa. The effects of kallikrein therapy on 25 males attending an infertility clinic was assessed, regarding endogenous spermatozoal ATP content, as well as other semen parameters. Thirteen of the 25 patients(More)
The effects of glucosidase inhibition on postprandial glucose tolerance was studied in 11 insulin-dependent diabetics. In comparison with placebo, 50 mg miglitol was able to lower the incremental glucose response significantly at 30 minutes and 60 minutes when insulin was injected: (i) 30 minutes before the meal (2,3 +/- 0,5 mmol/l v. 0,37 +/- 0,2 mmol/l; P(More)
This study attempts to provide guidelines for the extraction and estimation of ATP from spermatozoa. The conditions of extraction of ATP from spermatozoa using trichloroacetic acid were optimized. The efficiency of this extraction procedure was compared to that using boiling Tris buffer. Three commercially available kits which use the firefly luciferase(More)
The rates of remission after a course of antithyroid drugs in 71 black and 45 white patients with Graves' disease were compared. One year after stopping therapy 27% of blacks and 47% of whites were in remission (P less than 0.01); at 2 years the proportions were 7% and 27% respectively (P less than 0.05). Small size of goitre only was a weak predictor of(More)
In 2 out of 3 cases of retrograde ejaculation treatment with clomipramine hydrochloride resulted in normal ejaculation and conception. The 3rd patient was only partially helped by the drug. The mechanisms of ejaculation, the causes of retrograde ejaculation, the management of the condition and the relevant pharmacological features of the tricyclic(More)
ATP levels in human spermatozoa have been positively correlated with good motility. This has given rise to the impression that good ATP levels per se are related to good motility, i.e., the higher the ATP level, the better the motility and fertilizing potential. There was no direct correlation between motility percentage, forward progression, viability(More)
OBJECTIVES Comparison of 60 degrees mydriatic retinal photography, in screening for diabetic retinopathy, with diabetes clinic doctors, formal ophthalmological assessment, and with one or two 45 degrees fields. DESIGN Consecutive subjects screened by clinicians and photography, and selected eyes evaluated by an ophthalmologist. Randomized photographs(More)
