The demonstration of the succinic dehydrogenase system in Bacillus subtilis using tetranitro--blue tetrazolium combined with techniques of electron microscopy.

Activity of the succinic dehydrogenase system was studied in Bacillus subtilis utilizing combined techniques of cytochemistry and electron microscopy. Organisms were incubated in a medium containing tetranitro-blue tetrazolium (TNBT) which served as an electron acceptor. Enzymatic activity, as evidenced by deposition of TNBT-formazan, was found on membranous organelles associated with the cytoplasmic membrane and septal plasma membrane, the nuclear area, and the plasma membrane. Flagella, approximately 190 A in diameter, with thorn-like projections protruded through the cell wall. Tangential-oblique sections of the cell wall showed many pores approximately 220 A in diameter with a center-to-center spacing of approximately 450 A.

Embolization of the ophthalmic artery for control of epistaxis: report of two cases.

Embolization of the internal maxillary artery, an accepted method for control of severe or recurrent posterior epistaxis, usually involves the ipsilateral artery, but occasionally the contralateral vessel and the facial arteries as well. Such endovascular treatment may fail if the vascular supply to the bleeding vessels originates in derivative branches of the ophthalmic artery. We report two unusual cases in which embolization of the ophthalmic artery was performed to control epistaxis. The first patient had a prosthetic eye. In the second, sight in one eye was sacrificed after careful consideration in order to prolong life.

Neuro-ophthalmologic dilemma: chronic optic neuritis?

A patient with an 8-month history of chronic progressive visual loss was referred to the Neuro-ophthalmology Consult Office of Washington University with a diagnosis of chronic optic neuritis. Previous diagnostic studies, including CAT scan, had been negative. Because chronic progressive visual loss is considered a hallmark of mass lesion, more vigorous investigation, including repeat CAT scans, was undertaken, leading to the diagnosis and removal of a 2 cm meningioma.
