[The hepatitis B virus markers, in leprous patients (author's transl)].

The hepatitis B virus markers were studied on 553 leprous sera and 100 controls sera. HBs Ag detected by RIA were present on 25,4% of leprous and 12% of controls; the anti-HBs by RIA were revealed in 44,1% of patients out 38% of controls. The leprous was not carrying this markers were HBe Ag or anti-HBe or anti-HBc positive.

[The value of tomodensitometry in the treatment of carcinoma of the uterus (author's transl)].

The authors performed pelvic and lumbo-aortic tomodensitometry (TDM) in 67 patients with invasive carcinoma of the cervix. Localisation of the cervix is aided by the insertion of a vaginal marker and by opacification of the bladder and rectum. The density and appearance of tumour tissue are identical to those of normal uterine muscle.

[Attempt to induce, in the rat, a hepatitis of cirrhotic origin, using amino steroids: holaphyllaminol or amino 3-beta hydroxy-20-beta pregnene-5].

Holaphyllaminol, or Amino-3 beta-Hydroxy-20-beta Pregnene-5, was administered by gastric tube to male Wistar rats at dose of 50, 100 and 200 mg/kg/24 hr respectively, during 10, 20, 40 and 80 days. This substance provokes hepatic lesions beginning at the periportal region, the characteristics of which are a cholestasis, a canalar proliferation and a fibrosis. The interest of these alterations lies in the fact that they present the same features as certain human chronic hepatitis; their progression, a function of the dose of the toxin and the duration of treatment, may make possible to realisation of a model of experimental chronic hepatitis.
