Species differences in the intestinal transport of p-aminobenzoic acid
Comparative Biochemistry and Physiology, 1966Abstract 1. 1. The in vitro small intestine of the rat and hamster did not transport p-aminobenzoic acid (10−6−10−3) against a concentration gradient, while that of the mouse and flying squirrel did. 2. 2. This asymmetric distribution did not exceed that predicted on the basis of the potential differences across the intestine.

Production of p-Aminobenzoic Acid by the Tubercle Bacillus
Nature, 1945MANY workers have claimed that the common sulphanilamides in high concentrations may modify the course of experimental tuberculosis in animals. Much better results have been obtained, however, with the diaminodiphenyl-sulphone and some of its derivatives, for example, promin and diasone.

P‐aminobenzoic acid as a sunscreen and its behaviour on the skin
International Journal of Cosmetic Science, 1981SynopsisPABA (p‐aminobenzoic acid), a highly regarded sunscreening agent, has recently been shown to exhibit different absorption characteristics when applied to excised hairless mouse epidermis than when in dilute alcoholic solution. In the present study the cause of the differences was investigated.The results show that at normal application amounts,

Gravimetric determination of copper(II) with p-aminobenzoic acid
Talanta, 1968A method has been developed for the gravimetric determination of 20-100 mg of copper(II) with p-aminobenzoic acid. Ag, Hg(II), Pb, Al, Fe(II), Bi, Sb(III) and Sn(II) interfere, but Zn, Co(II), Ni and Cd do not. The precipitate can be weighed after drying at 80-100 degrees , or can be ignited to copper(II) oxide at temperatures above 400 degrees , and ...

Plasmodium falciparum: A Homologue of p-Aminobenzoic Acid Synthetase
Experimental Parasitology, 1999The sulfa drugs are a large group of antibiotics which include the antimalarial sulfadoxine, the sulfonamide component of Fansidar, Sulfadoxine acts synergistically with pyrimethamine, the other component of Fansidar, because it inhibits distinct enzymes of the folate biosynthetic pathway in Plasmodium falciparum (Chulay et al. 1984). Although Fansidar

Derivatives of p-aminobenzoic acid and their action on the growth of bacteria
Antonie van Leeuwenhoek, 1953Various derivatives of P.A.B. obtained by introduction of substituents in the benzene-nucleus have been examined for their action on the growth ofAerobacter aerogenes in a simple synthetic medium and ofDiplococcus pneumoniae in ascites-broth without peptone.

p-Aminobenzoic-Acid-Related Compounds and Systemic Lupus
Archives of Dermatology, 1978To the Editor— Fisher's statement about the cross reaction of glyceryl p-aminobenzoic acid (PABA) with p-aminosalicylic acid, p-phenylenediamine, procaine, and sulfa derivatives should be of interest to clinicians (Archives113:1299-1300, 1977). It is well known that lupus and lupus-like syndromes are more frequently diagnosed presently than in the ...
