Single plane cineangiographic study of normal left ventricular volumes in human subjects

Single plane cine angiographic estimation of left ventricular volumes in 10 Indian subjects with no evidence of left ventricular disease was carried out. The figures obtained were end diastolic volume 72.43+/-10.27 ml/M2, endsystolic volume 26.82+/-7.46 ml/M2, stroke volume 45.61+/-12.23ml/M2, ejection faction 62.30+/-10.90%. These values compare well with those already reported in literature from Western countries. No study in Indian subjects was available for comparison so far.

A study of heterosis in upland cotton (Gossypium hirsutum L.)

Heterosis (over mid parent) and "useful" heterosis (over commercial variety H14) estimates were obtained from a line x tester analysis of crosses involving thirteen diverse female parents with two locally adapted varieties H14 (local standard) and J34. Marked heterosis was observed for seed cotton yield, boll number and halo length. The values of positive heterosis and "useful" heterosis for seed cotton yield ranged from 28.1 to 87.0% and 20.1 to 45.5%, respectively. The overall study of heterosis revealed that female parents PRS-72 (USSR), 5904F (USSR) and MCU-5 (Madras Cambodian Uganda Selection, Coimbatore) were among the top three females, showing considerable heterosis in crosses with H14 and J34 for seed cotton yield and fibre properties. The practical difficulties in exploiting the phenomenon of heterosis and possible experimental approaches in upland cotton are discussed.

Antireticulin antibodies in dermatitis herpetiformis and adult coeliac disease. Their relationship to a gluten free diet and jejunal histology

Antireticulin antibody was present in 17% of sera from thirty-five patients with dermatitis herpetiformis, 45% from twenty-eight patients with adult coeliac disease and none of thirty healthy controls. There was a higher incidence of antireticulin antibody(a) in patients on normal diets than in those on gluten free diets, and (b) in patients with subtotal villous atrophy than in those with partial villous atrophy. Two patterns of tissue staining were demonstrated, one of which was almost invariably associated with jejunal subtotal villous atrophy. The Ig class of the antibody was IgG in all instances but in 64% antibody of the IgA class was also present.

Jejunal mucosal immunoglobulin-containing cells and jejunal fluid immunoglobulins in adult coeliac disease and dermatitis herpetiformis

Immunoglobulin-containing plasma cell densities in the jejunal mucosa and serum and jejunal fluid immunoglobulins have been measured in patients with adult coeliac disease and dermatitis herpetiformis with and without jejunal mucosal abnormality. Studies were performed in patients before and after treatment of the jejunal lesion.Total immunofluorescent plasma cells were increased in untreated adult coeliac disease and dermatitis herpetiformis patients with jejunal lesions, but in general the normal predominance of IgA > IgM > IgG was found. There was no difference from controls in IgA-containing cells in the two conditions before or after treatment. The numbers of IgM-containing cells were significantly increased both before and after treatment in groups of patients with adult coeliac disease and dermatitis herpetiformis who had jejunal lesions. IgG-containing cells were significantly raised in only the before-treatment groups. Patients with dermatitis herpetiformis without jejunal lesions, even whilst on gluten-containing diets, had normal numbers of immunoglobulin-containing cells. IgA and IgM jejunal fluid immunoglobulins were significantly raised in dermatitis herpetiformis and adult coeliac disease.It is concluded that patients with dermatitis herpetiformis with jejunal morphological abnormality have a comparable immunological disturbance of the jejunal mucosa to that found in adult coeliac disease.
