In vivo eradication of Friend virus as an experimental HIV-model, by combination of zidovudine, acriflavine and an ellipticine analogue. Possible application to the treatment of human pre-AIDS?

Simultaneous administration of zidovudine, acriflavine and celliptium to Friend virus-injected mice eradicates the virus, as evidenced by the impossibility of the treated-mouse serum, when injected to virgin recipients, to induce spleen foci formation. An adapted preliminary protocol given to patients in whose p 24 antigen was present in the blood, lead to a considerable reduction of that marker. The cures lasted 3 weeks, and were repeated after 3-week intervals. Since p 24 antigen returns to pre-treatment levels at the end of the interval, research should concentrate on the maintenance of the effect during the interval.

Changes in the level of blood suppressor CD8+CD57+ lymphocytes, when HIV-1 p24 antigen reappears in the blood.

Using the marker Leu2 + Leu7 + to detect the CD8 suppressor cells (CD88+CD57+), we have observed that their blood level, which increases after primoinfection, during the latent period, increases still further just before and when the p24 antigen returns and is present in the blood. Its ratio over cytotoxic CD8+ cells remains high during the AIDS period, though the absolute number decreases.

The in vivo effect of ellipticine analogues on the blood concentration of Friend virus: a murine model for studying anti-HIV drugs.

The viremia of a mouse carrying a murine retrovirus, the Friend virus, was taken as a model for screening drugs which could be active on the human HIV retrovirus. Ellipticine and two of its analogues injected ip at appropriate doses drastically reduced the viremia of the Friend virus-injected mice, as measured by transfer of their serum on day 8 of the treatment to secondary recipients and numeration, in the spleens of the latter, of the foci the remaining virus had induced. Since phase I and II trials have already been published (for leukemia treatment), the efficacy of those drugs on HIV-1 positive AZT-resistant patients can be tested directly.

Radical tumor excision and cosmetic balance in the surgical treatment of breast carcinoma: biquadrantectomy.

The present trend in favor of conservative surgery is in contrast with histopathological findings of multicentric breast carcinoma, which may be responsible for the occurrence of relapses in spite of the use of radiation therapy. As a consequence, conservative surgery appears to be inadequate, especially when tumor size exceeds 2 cm. Therefore for tumors up to 4 cm in size, which are not adherent to the pectoral fascia, we propose the excision of two quadrants with concomitant operation on the contralateral breast resulting in a more symmetrical and therefore cosmetic effect. This is a more radical procedure than the removal of the one quadrant.
