[Three cases of spontaneous bilateral external carotid-cavernous sinus fistula (dural arteriovenous shunts in the region of the cavernous sinus) (author's transl)].

Since Fincher reported a case with arteriovenous fistula between the external carotid artery and dural sinus, many type of cases have been reported. On the other hand, so called the external carotid avernous fistula has been recognized less 20 cases in literature. We have observed three additional cases of dural arteriovenous shunts in the region of the cavernous sinus. Case 1. A 52 year old woman had suffered from left side sever headache. There was weakness of the left extraocular muscles and left ptosis. A bruit was heard over the left orbit. She was treated for hypertension since 38 year old. And she has no history of recent trauma. Selective internal and external carotid angiographies showed the bilateral external carotid cavernous sinus fistula. No operative treatment was performed in this case and the symptomes disappeared with decrease of blood pressure. Case 2. A 50 year old man came to this clinic with chief complaints of right ptosis, diplopia and headache. He was treated for diabetes mellitus and hypertension for six month...

[Clinical manifestation of muco- and pyocele of the sphenoid and ethmoid sinuses (author's transl)].

We, neurosurgeons, frequently encounter patients whose chief compiants are visual disturbance, disorder of the ocular movement, trigeminal neuralgia and/or panhypopituitarism wich have been called as superior orbital fissure syndrome or orbital apex syndrome. Among these, there might be considerably high incidence of mucocele or pyocele of posterior ethmoid sinuses. We have experienced 12 cases of mucocele in past 5 years, which were confirmed by operation. The most reliable method to diagnose mucocele or pyocele at this moment is by the radiogical procedures, and among all, tomogram of the skull is essential. This procedure not only clearly demonstrates the existence of mucocele in a certain sinus but also provides us informations about the surrounding bony stracture. Diagnosis becomes more definite if the epipharyngography demonstrates no filling of postive contrast medium into suspected paranasal sinuses. Treatment of choice for this disease is firstly drainage of mucocele or pyocele by transnasal approach, to avoid postoperative meningitis or brain abscess, and secondarily dissection of the arachnoidal adhesion around the optic chiasm by intracranial approach if it is necessary. Recently, we perform the drainage of mucocel and peeling off of affected mucosa via transnasal route using microsurgical technique. Results are all satisfactory.

Purification of an immunosuppressive principle from Ehrlich carcinoma ascites.

An immunosuppressive factor was purified from Ehrlich carcinoma ascites by the combination of ultrafiltration and Sephadex chromatography. The resulting product showed 50% reduction in the number of splenic plaque-forming cells in mice immunized with sheep red blood cells when as low as 50 mug dose was given twice intraperitoneally before erythrocyte injection. The molecular size of the product was between 30,000 and 100,000, and it was relatively heat unstable.
