Hepatitis B surface antigen in human tears.

The incidence of hepatitis B virus infection has been increasing every year in the United States, particularly among medical personnel. Only half of these cases are associated with exposure to blood or blood products. Respiratory, fecal-oral, and venereal methods of transmission of hepatitis B virus infection are supported by epidemiological evidence and by the demonstration of hepatitis B surface (HBsAg) antigen in several body secretions.

Pharmacokinetics of cefamandole in the presence of renal failure in patients undergoing hemodialysis.

The pharmacology of cefamandole in seven patients with stable renal insufficiency and in eight patients undergoing hemodialysis was determined. All patients had creatinine clearances less than 5 ml/min. The half-life of cefamandole in those patients with stable chronic renal failure was 7.

Immunoglobulin E antibodies to pollen allergens account for high percentages of total immunoglobulin E protein.

The quantities of immunoglobulin E (IgE) antibodies to grass or ragweed allergens were measured by an immunoabsorption in the serums of patients sensitive to one of these allergens. IgE antibodies to grass or ragweed allergens accounted for means of 30 and 29 percent of the total IgE protein. After the ragweed pollination season, the levels of serum IgE antibodies to ragweed allergens rose dramatically and in postpollination serums they accounted for 39 percent of the total IgE protein with a range from 13 to 50 percent.

[Asbestos as an envoronmental carcinogen (author's transl)].

Relations between asbestosis and bronchial carcinoma and also since a long time for diffuse malignant pelural and peritoneal mesothelioma have been ascertained for professional exposure to asbestos. On the other hand such relations can be proved statistically for non-professional environmental influence only with malignant serosa tumors. Their increased occurrence goes parallel to the hyaline (calcified) pleura-plaques, to another professional and non-professional consequence of asbestos dust inhalations.
