[Cellular immunity in 18 cirrhotic African carriers of hepatitis B virus surface antigen (HBsAg)].

The cell mediated immunity has been studied by 3 different tests on a population including 32 african patients with cirrhosis; amongst those, 18 were HBs Ag carriers and 14 were Hbs Ag-. In those 2 groups, the intradermal tuberculin test and the DNCB cutaneous test showed a striking imminutary deficiency in half cases. The lymphoblastic transformation induced by PHA gave less striking results.

[Examination of the enzymatic functions of the normal liver in black Africans (Apropos of 50 Senegalese cases)].

In order to establish the hepatic enzymogram in healthy African black people, four enzymes have been studied in 50 apparently healthy male Africans: transaminases (GOT, GPT), alcaline phosphatases, ornithine carbamoyltransferase (OCT) and gamma-glutamyl transpeptidase (GGT). The findings do not show any difference with the usually admitted levels in European countries, except for alcaline phosphatases which are situated at the upper limit of the normal.
