RESUMO
Male infertility is a distressing and often ill-understood clinical problem. Most infertile males are treated empirically as we know so little about the endoctrine control of spermatogenesis. Reports on male infertility in Nigeria have stressed the role of varico-coles and bacterial chronic prostatitis in the aetiology of this syndrome. Inspite of the acknowleged high incidence of (pulmonary) tuberculosis in our mileu; tuberculosis as a cause of male infertility in Nigeria is underestimated

A simple and rapid method for the demonstration of acid mucopolysaccharide using colloidal iron, sulphosalicylic acid ammoniacal silver is described. Satisfactory staining of human as well as animal tissue was obtained following 10% neutral formol saline fixation and paraffin sections. There were no oxidation or hydrolysis sequences. The staining specificity was controlled using methylation and saponification. The distribution of the acid mucopolysaccharide demonstrated by this method was identical with that obtained by colloidal iron Perls' reaction.

The findings in 147 unselected consecutive post mortem coronary arteriograms carried out at the University College Hospital, Ibadan, are analysed. The so-called third primary division of the left coronary artery was noted in 35% of cases which is much less than the 74% quoted for the South African Bantu. In atrial blood supply, there was a definite predominance of one coronary artery. The predominant artery to both atria originated in one-third of cases from the right coronary, in another third from the left coronary and in the remaining third from both coronary artery systems respectively. Only in eight instances was atherosclerotic disease noted and even then, this was of the mildest degree with only minimal and slight intimal irregularity. This further explains the known rarity of myocardial infarction as a cause of death in the Nigerian. The study forms a useful basis for the baseline anatomy of the coronary arteries in Nigerians as a prelude to in vivo studies in the cardiomyopathies.
