[Experimental study on relieving blood stasis of skin flaps using leeches].

Isolated congested flaps in lower abdomen of rats were treated by application a method of sucking blood with medical leeches. The results were shown that survival rate of sucking blood group was 93.9%, non-sucking blood group was only 14.3% and small incision bleeding group in which incision was rinsed by Heparin-physiological saline was 25%. It has proved that this method has a very good effect on relieving blood stasis of tissue. We think that this method can be put to use clinically.

[Morphology, diagnosis and differential diagnosis of mesothelioma].

Forty cases of mesothelioma biopsied and autopsied from 1961 to 1985 were studied and analysed as to their morphology, diagnosis and differential diagnosis. Mesothelioma had complex histologic types. The tumor cells varied in size and shape and were characterized morphologically by the coexistence of biphasic differentiation, adenoid and microvilli formation. The pathologic diagnosis is made according to the feature of biphasic differentiation, or coexistence of epithelioid and spindle tumor cells. It should be emphasized that the tissue sections are taken from multiple areas. Usually, the correct diagnosis is made in correlation to the clinical manifestations. For difficult cases of the diffuse mesothelioma, electron microscopy is needed to differentiate from metastatic adenocarcinoma and spindle cell sarcoma etc.

[Significance of ultrastructure of peripheral nerve tumors in pathological and differential diagnoses].

Biopsy material fixed with formalin in 10 cases of peripheral nerve tumors and 5 soft tissue tumors were studied with special reference to the significance of the ultrastructure of peripheral nerve tumors in histopathological and differential diagnosis. The results demonstrated that electron microscopic examination of formalin-fixed tissue may still reveal their ultrastructural characteristics. This is of certain practical value in pathological and differential diagnosis in some difficult peripheral nerve tumors.
