Inheritance of monoclonal rheumatoid factor cross-reactive idiotypes in primary Sjogren''s syndrome (pSS). Comparative studies of a rabbit polyclonal anti-idiotype and 17109 monoclonal anti-idiotype

Abstract. A comparison of the presence of two idiotypes, one identified by a rabbit polyclonal anti-idiotypic antibody, first found on a cryoprecipitable IgM.± rheumatoid factor (RF) from an SS patient (3rd SS) and the 17109 idiotype, identified by a monoclonal antibody was performed in 106 sera and eight minor salivary gland biopsies of Sjögren's syndrome (SS) patients and 125 sera from age-sex matched normal controls. Of 106 of SS patients' sera 36 had immuno-globulins positive for the 3rd SS idiotype. 17109 activity was more prevalent in SS patients positive for the polyclonal anti-idiotype 3rd SS, than those with negative idiotype (9/36 VS 2/70 times2= 12.53 P <0.005). Cross inhibition studies, however, revealed that the polyclonal anti-idiotype binding was not inhibited by the 17109 moAb. 3rd SS and 17109 anti-idiotypes were reacted with immunoglobulins in the serum of 3–5% and 1.7% of normal human sera respectively. Immu-nohistologic studies demonstrated that 4/8 and 2/6 minor salivary gland biopsies had infiltrating plasma cells containing immunoglobulins bearing the 3rd SS and the 17109 idiotypes, respectively. The inheritance of both idiotypes was investigated in sera of 4 SS kindreds. In two kindreds with 3rd SS positive pro-bands, the idiotype was detected in 3 first degree relatives of the same generation. 17109 activity was detected in the serum of a sister of the positive proband who had a high RF titer. These results suggest that the 17109 moAb recognizes a different epitope of that of the 3rd SS. The idiotypes of monoclonal RFs are not inherited and probably are produced by plasma cells infiltrating the labial minor salivary glands of SS patients.     

Genetic factors controlling inheritance of susceptibility to 1,2-dimethylhydrazine

Summary Reciprocal crosses were made between AKR/J, a 1,2-dimethylhydrazine (DMH)-resistant mouse strain, and SWR/J, a sensitive strain. The F1 hybrids were tested with DMH and methylazoxymethanol (MAM), two colon carcinogens. Either DMH (20 mg/kg body weight) or MAM (35 mg/kg body weight), a metabolic derivative of DMH, was injected weekly for 10 weeks. In each group of 35 mice, 10 were injected with tritiated thymidine (25 Ci) 1 week after the sixth injection of DMH and MAM for the evaluation of proliferative characteristics and the number of foci of dysplasia occuring in 325 m of distal colonic mucosa. At 27 weeks after the first injection of the carcinogen, the colons of remaining mice were opened longitudinally and the number of tumors enumerated. Compared with DMH-treated mice, the number of foci of dysplasia per mouse, the percentage of tumor-bearing mice, the number of tumors per animal, and the number of tumors per tumor-bearing animal induced by MAM were severalfold higher. This would suggest the presence of a gene(s) repressing metabolism of DMH to MAM. Moreover, differences in response to the carcinogens were observed between the sexes. In contrast to males, females treated with both DMH and MAM had significantly greater numbers of tumors per animal, tumors per tumor-bearing mice, and a greater proliferative response with extension of S-phase cells to the upper third and luminal surface of crypts. Among males, those with the X^AKR/Y^SWR heritage appeared more resistant than X^SWR/Y^AKR males, particularly in their response to MAM. A twofold difference in the number of foci of dysplasia per mouse, tumors per animal, and the number of tumors per tumor-bearing animals was seen. Analyses of the response to DMH and MAM by F1 reciprocal hybrids of the AKR and SWR strains have shown a complex inheritance pattern governing susceptibility to DMH. Resistance to the carcinogen is provided by at least two specific repressor genes, one governing metabolism of carcinogen from DMH to MAM, and the other controlled by gender. Genetic factors contributed by the AKR female appear to convey additional resistance to male progeny, suggesting more than one gender-related gene.Supported in part by CA 08748 from the National Cancer Institute and by CA 26674 from the National Cancer Institute through the National Large Bowel Cancer Project     

Inheritance of mitochondrial and chloroplast genome markers in backcrosses of Chlamydomonas eugametos x Chlamydomonas moewusii hybrids

Summary Southern blot analysis of AvaI-digested total cellular DNA from the interfertile species Chlamydomonas eugametos and Chlamydomonas moewusii with a coxI mitochondrial gene probe from Chlamydomonas reinhardtii revealed single hybridizing fragments of 5.0 and 3.5 kb, respectively. The transmission of these mitochondrial DNA physical markers along with that of chloroplast genetic markers for resistance to streptomycin and resistance to erythromycin was studied in the fourth backcrosses of F₁ hybrids to one or the other parent. Viability in these backcrosses is high in contrast to the cross C. eugametos x C. moewusii and its reciprocal which are associated with considerable meiotic product lethality. The resulting zygospores were found to transmit the mitochondrial and chloroplast genome markers uniparentally or preferentially from the mating-type-plus parent. Thus the species pair C. eugametos and C. moewusii differs from the pair Chlamydomonas reinhardtii and Chlamydomonas smithii in which mitochondrial genome markers are transmitted uniparentally by the mating-type minus parent, while the chloroplast genome markers are transmitted uniparentally by the opposite parental mating-type (Boynton et al. 1987).     

Genetic analyses of gustation in the fowl

Preferences towards quinine sulfate (QS) and dextrose (DEX) were tested in purelines and reciprocal crosses of two lines of chickens that had undergone 22 generations of selection for high and low juvenile body weight. Parental line-F₁ comparisons provided evidence for non-additive genetic variation for hedonic sensitivity towards QS and DEX, though in opposite directions. Additive genetic variation appeared to influence the preference ratios for both stimuli at super-threshold concentrations. These results are discussed with regard to their evolutionary implications.

Prevalence of diabetes mellitus and impaired glucose tolerance in parents of women with gestational diabetes

Summary Nuclear families of non-insulin-dependent diabetic (NIDDM) patients are uncommon, as usually one or both parents have died. In order to aid identification of complete nuclear families, we have ascertained the disease process at a younger age by studying subjects with previous gestational diabetes. One hundred women who had had gestational diabetes, age (±SD) 38 (6) years, were screened by fasting plasma glucose (fpg). Sixty-one were found to have either fasting hyperglycaemia (5.5fpg<7.8 mmol/l) or diabetes. Of these women 35 had both parents alive and the parents of 14 of these women agreed to the assessment of their metabolism by a continuous infusion of glucose with model assessment (CIGMA). Seven probands had impaired glucose tolerance (IGT) and seven were diabetic. They were age 35 (4) years and had body mass index (BMI) 26 (5) kg/m². The parents were aged 62 (6) years and had BMI 29 (6) kg/m² and their affection status was defined as presence of glucose intolerance (fpg or post-infusion achieved plasma glucose level >2 SD of an age and obesity matched population). In the 14 families, five probands (36%) had neither parent affected, six (43%) had one parent affected and three (21%) had both parents affected. Only three probands had a parent with diabetes as defined by World Health Organisation criteria. We concludes that the study of women who have had gestational diabetes allows detection of probands with diabetes or impaired glucose tolerance, who have both parents available for study. A substantial proportion had neither parent affected with impaired glucose tolerance or diabetes, similar to the nuclear families of NIDDM patients. The results are in accord with studies of nuclear families of NIDDM patients in suggesting polygenic inheritance or environmental influences rather than autosomal dominant inheritance with high penetrance.Abbreviations IGT Impaired glucose tolerance - GTT glucose tolerance test - NIDDM non-insulin-dependent diabetes mellitus - fpg fasting plasma glucose - apg achieved plasma glucose - CIGMA continuous infusion of glucose test - BMI body mass index     

Some Consequences of being the Wrong Child: Effects of the Intergenerational Transmission of an Ideal‐Ego

In this paper the author considers a not uncommon group of patients seen in analytic work. These are people who present themselves for treatment because they feel that there is something ‘wrong with themselves’, and it is this belief about themselves that is their problem. They are usually people who have not achieved their potential in life; who may be dissatisfied in their relationships and/or with their level of success in their work. They often suffer from depression, symptoms of anxiety or psychosomatic complaints. In this way their belief in their sense of ‘wrongness’ is self‐confirming and to this extent they do have something wrong with them although the particular manifestations, of what is wrong, can vary considerably. However, it is what these people have in common, their fundamental belief in being ‘wrong’, which the author is going to address.
