FLAGELLATE PROTOZOA AS AN ETIOLOGIC FACTOR OF DYSENTERIC DIARRHEA

Tobacco smoking as an etiologic factor in disease; cancer.

Tobacco Smoking as an Etiologic Factor in Disease. I. Cancer*

Clinicians seem to be in wide disagreement on the relationship between tobacco and cancer. Ochsner (l) and Lickint, (2), for example, consid ered smoking an important etiologic factor in can cer of the lung. Johnson (3) did not consider spe cifically the relation between smoking and cancer, but he believed that the only pathologic effect of heavy smoking is congestion of the pharynx. The clinic...

PURPOSE To investigate clinical manifestations and response to antiviral therapy of 8 patients with cytomegalovirus (CMV)-induced corneal endotheliitis who were diagnosed and treated at 2 university hospitals in Japan. DESIGN Retrospective, consecutive, multicenter case series. PARTICIPANTS Eight eyes of 8 patients diagnosed with active CMV corneal endotheliitis at Kyoto Prefectural Univers...

Isolation of intracellular symbiotes by immune lysis of flagellate protozoa and characterization of their DNA

A new method dependent on immune lysis is described for the isolation of intracellular symbiotes from two species of flagellate protozoa Blastocrithidia culicis and Crithidia oncopelti. The symbiote-containing flagellates are exposed to complement and antisera prepared in rabbits against symbiote-free organisms. The immune lysis seems to weaken the plasma membranes of the flagellates so that su...

Failed first trimester pregnancy termination: uterine anomaly as etiologic factor.

Failure of first trimester pregnancy termination is an uncommon, although potentially serious complication of attempted therapeutic abortion. We report our experience in four patients with unsuspected congenital uterine anomalies in whom attempted pregnancy termination procedures failed to completely ablate the products of conception. When dilatation and curettage fails to produce embryonic tis...
