Human early pregnancy factor: application of the monoclonal antibody anti-HuLyt 3 in the rosette inhibition test and in a cellular radioimmunoassay.

Using the monoclonal antibody anti-HuLyt 3, raised rosette inhibition titres were observed when lymphocytes were preincubated with early human pregnancy sera, although this was not a consistent finding. Results obtained from a cellular radioimmunoassay suggest that this enhancement of rosette inhibition is not due to interference with antibody binding.

Quantitative morphometric and histopathological study in rabbit oviducts after microsurgical treatment.

The histopathological lesions remaining after microsurgical tubal reanastomosis were investigated quantitatively by light microscopy and qualitatively by transmission and scanning electron microscopy. In 23 rabbit oviducts, the influence of the suture material poly-p-dioxanon and polyglactin-910 and post-operative time interval (6 and 12-15 weeks) was evaluated and compared with non-anastomosed contralateral oviducts as well as with those of unoperated controls. Except in the controls, partial deciliation, pathological kinocilia structure, microvilli and cytoplasmic blebs were found in all tissues, demonstrating an almost complete endosalpingeal restoration.

Chronic placentitis--a clinicopathological study.

Between 1978 and 1983 1240 singleton placentas were examined macroscopically and histologically. In 82 cases (6.6%) a "chronic placentitis" was diagnosed.

[Differential diagnosis of the axillary lymph node].

The authors report on clinically abnormal palpatory findings in the axilla. The radiology and sonography of these findings is described, as well as differential diagnosis between normal findings and benign as well as malignant changes. If it is not possible to confirm a benign aspect even by means of examination via relevant equipment, histological clarification must be sought whenever there is a new palpatory finding or if changes are noted.

[Initial clinical experiences with grid mammography].

The article reports on a comparison between 100 x-ray films (preparation radiographies, mammographies) with grid and a film/foil combination on the one hand, and conventional x-ray technique with material testing x-ray film on the other. The clear superiority of grid mammography is demonstrated by means of case examples.
