A new synthetic material was developed by ASAHI Chemical Industry Co., Ltd., Tokyo, Japan. In vitro studies revealed selective bindings of cholesterol, LDL (low density lipids) and beta-lipoprotein by this material. Maximal bindings were reached within 1 min, and therefore, the affinities of the LDL-adsorbent to these lipid components seem to be high. In contrast to these results the plasma values of HDL (high density lipids) and apoprotein A remained nearly unchanged. Triglycerides were removed only moderately. Investigations about lipid removing capacity of the new material with the plasma of patient with familiar hypercholesterolemia and studies about interactions with the complement system were also promising. Synthetic materials which are under development in G.D.R. showed similar lipid binding capacities.

Extensive surgery for primary malignant lymphoma of the heart.

The surgical treatment of primary malignant lymphoma of the heart in a 43-year-old man is reported. The tumor was extensively resected together with the right atrial wall and both venae cavae, and the resulting defect was repaired with a bovine pericardial patch. The postoperative course was fairly stable for more than 7 months following surgery, under a regular chemotherapy regimen. The patient died of acute pneumonia on the 234th postoperative day. The autopsy findings confirmed the diagnosis of primary malignant lymphoma of the heart.
