The association of HLA with juvenile diabetes mellitus in Newfoundland.

In view of the reported variation in the association between HLA antigens and Juvenile Diabetes Mellitus (J.D.M.) among different Caucasian populations, we have undertaken a study of these antigens among 44 Caucasian Newfoundlanders and 135 matched controls. We have also studied the allotypic markers for Immunoglobulin G (Gm) and variants of C3 among 36 of these patients. We found that both HLA--B8 and B15 were increased among the patient group, resulting in a relative risk of 3.9 and 4.4 respectively. While these values are the highest to be described for J.D.M. among Caucasians, and fell outside the 95% confidence intervals for the combined relative risk calculated from published series, it is still possible that they can be accounted for by sampling. The combination of the two antigens increased the relative risk for J.D.M. in an additive fashion. Additionally, we also found that the combination of HLA B8 and B18, but not B15 and B18, also appear to act in an additive manner. The incidence of Gm allotypes and variants of C3 were not different in the J.D.M. group from those observed among controls.

Prolonged survival after immunotherapy (irradiated cancer autografts) or mammary cancers, assessed by a measure of therapeutic deficiency.

Sixteen women, twelve with stage 2 and four with stage 3 mammary cancers, were given autografts of irradiated cancer cells immediately after simple mastectomy and before postoperative radiotherapy, as a pilot trial with entry limited for ethical and operational reasons. Entry was based upon the presence of the poor prognostic features of tumor diameter exceeding 4 cm, fixation to skin or fascia or presence of axillary lymph nodal metastases. Actuarial survival curves for a period of six years show significant (p less than 0.01) prolongation of survival of the small autografted group (63% at six years) compared to that (30% at six years) of 139 ungrafted stage 2 mammary cancer patients treated by mastectomy and postoperative radiotherapy. The concept of deficiency of a treatment based upon person-years lived is introduced and used to analyze the data. The observations and analyses support the theoretical concept that irradiated autografts of cancers may sensitise residual cancer to subsequent conventional radiotherapy and in the process can activate systemic immunological restraints.

Preclinical warning of recrudescent mammary cancers by pregnancy-associated alpha-macroglobulin.

Nine of 30 mammary cancer patients developed metastases during 13-94 months after mastectomy. All 9 patients had elevated blood levels of pregnancy-associated alpha-macroglobulin (PAM) 1-21 months before conventional detection of metastases. Seven of the clinically well patients had PAM rises exceeding 90 per cent above the baseline and in 4 of these the PAM later fell to lower levels. PAM appears to have potential as an indicator of the growth of micrometastases.

Chromosome analysis of a simian virus 40-transformed mouse cell line and two variant sublines that are resistant to cytochalasin B1.

The chromosomes of an SV40-transformed mouse cell line, SVT2, were analyzed by the acetic-saline-Giemsa banding technique. By contrast to most established mouse lines, SVT2 cells possess a remarkably homogeneous chromosome complement and contain two copies of most chromosomes. However, trisomy for chromosome 3 is a distinct feature of this cell line. Chromosomes 1, 3, 14, and 19 have given rise to biarmed markers. Two Cytochalasin B-resistant sublines derived from SVT2 are also essentially diploid for all autosomes but contain only one chromosome X; they display an even greater homogeneity than does the SVT2 parental cell line. Each of the Cytochalasin B-resistant cell lines has lost one or several of the biarmed markers from SVT2 and new ones have appeared. Both cell lines have lost one copy of chromosome 3 and one chromosome X. The results presented illustrate the advantages of cells of defined chromosome constitution, like STV2 cells and derived sublines, to study specific interactions between transforming virus and host chromosomes. The possible role of SV40 in the maintenance of the pseudodiploid karyotype of SVT2 is also discussed.
