[Long-term outcome of type V lupus membranous glomerulonephritis].

Background: The long-term outcome of the pure form of WHO type V lupus membranous glomerulonephritis is apparently more benign than that of other forms of lupus glomerulonephritis. However 12% of such patients progress to terminal renal failure. The presence of proteinuria may be an indication of cytotoxic agents.

[Serum values of vitamins A, E, C and carotenoids in healthy adult subjects and those with breast neoplasia].

Serum values of retinol, carotenoids, tocopherol and ascorbic acid were assayed in healthy adult females (Group A: 20 cases) and in subjects with fibrocistic mastopathy (Group B: 20 cases), benign breast neoplasms, as fibroadenomas and intraductal papillomas (Group C: 18 cases), and breast carcinoma in situ (Group D: 36 cases). Retinol and carotenoids were evaluated by spectrophotometry using trifluoroacetic acid. Tocopherol was determined by a colorimetric method involving the reduction of Fe to Fe++ by tocopherol with the formation of a red complex of the Fe++ with alpha, alpha'-dipirydyl.

[Cellular immunity in mollusk hosts of schistosomes. Primary results regarding Biomphalaria glabrata].

Cell culture are obtained from the saccular part of the kidney of Biomphalaria glabrata in a medium derived from Schneider drosophilia medium. Two types of cells migrate from the explant: numerous amoebocytes and some fibroblasts. Migration of amoebocytes appears to be regular.

Radical mastectomy versus radical mastectomy plus internal mammary dissection. Five-year results of an international cooperative study.

From 1963 to 1968, the international group collected 1580 cases of breast cancer, randomized into two therapeutic groups: radical mastectomy and extended mastectomy. The data were processed on the UNIVAC 1107 computer of the I.N.
