This new drug has proved an excellent suppressant in a dosage of one product once a week ; when administered under supervision to an entire community it has been shown capable of breaking the malarial cycle. ‘ Daraprim ’ is tasteless and well tolerated ; it causes no discoloration of the skin. It is supplied as compressed products of 25 mgm., in packs of 6, 30, 250 and 1000. ‘DARAPRIM’B8AH0 PYRIMETHAMINE Issued in the French Union and in Tunisia and Morocco as ‘ Malocide ’ brand Pyrimethamine BURROUGHS WELLCOME & CO.

The SP.600 Spectrophotometer allows methods developed in the laboratory to be applied in the factory with the same ease, accuracy and economy. The graph above illustrates the performance of the instrument which is equipped with a glass prism monochromator and two vacuum photocells, and may be operated from suitably stabilised mains or a 12V battery. UNICAM INSTRUMENTS LTD ARBURY WORKS CAM BRIDGE UI3OE REVIEW ARTICLE THE PRESENT STATUS OF THE CHEMOTHERAPEUTIC DRUGS By S. R. M. Bushby, M .S c. (Brist.), Ph.D. (Lond.) Wellcome Research Laboratories, Beckenham, Kent T he Sulphonamides T he sulphonamides may eventually be replaced by antibiotics with wider antibacterial activity but they continue to be very popular in general practice because of the ease with which they are administered, and their relative freedom from serious side effects. Hypersensitivity is probably their only common disadvantage especially when applied locally in skin infections. Although experimentally the sulphonamides are the least active of the chemotherapeutic agents they are sometimes more efficient clinically than the antibiotics. For instance, in a recent comparison1 between the sulphonamides and penicillin for the treatment of pneumonia, there was no difference amongst males in the incidence of pleural complications but in females for some unexplained reason the sulphonamides were superior to penicillin; and again in controlled trials2 in the treatment of infantile diarrhoea, sulphadiazine has proved to be superior to chlortetracycline or chloramphenicol. Also because succinylsulphathiazole and phthalyl- sulphathiazole provide good cover with little risk of serious side effects they have been regarded3 as more desirable than the wide-spectrum antibiotics for prophylactic therapy against bowel infection in abdominal surgery. The sulphonamides are also recommended for combined therapy, e.g., with streptomycin in H. influenza meningitis4 and in brucellosis5, or with neomycin as an intestinal antiseptic6. P enicillin Penicillin is often reputed to be the least toxic of all the antibacterial drugs and therefbre it may be surprising to read that “To-day penicillin heads the list of medicinal agents in the frequency, diversity and severity of the sensitivities which it induces.
