Study of the effects of certain drugs on experimental porphyria in rats.

The effect of ethanol, phenobarbitone, griseofulvin or chloroquine on 3,4-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-induced porphyria in rats has been studied in experiments lasting up to 40 days. Ethanol, phenobarbitone or griseofulvin given later, in addition to DDC, resulted in a clearly greater porphyrin excretion and liver porphyrin concentration than with DDC alone. Chloroquine at first increased, then decreased porphyrin excretion and liver porphyrin was lowered. No drug without DDC was porphyrogenic.

Vegetables responsible for contact dermatitis of the hands.

Fifty-three patients having contact dermatitis on the fingertips showed positive patch tests with several vegetables the commonest being garlic, onion, tomato, and carrot in that order of frequency. Of several preparations, made from garlic onion, tomato, and carrot, the juices used as such gave the maximum number of positive patch test reactions. Lyophilization of the juices led to false-negative patch tests in some cases. Patch tests in the controls were positive in some cases but these were probably cases of latent hypersensitivity, because some of them, like the patients, showed positive reactions even with the diluted juices. The antigens in garlic and onion were extractable in water, ether, acetone, or alcohol and were also present in the essential oils of these vegetables. Infrared spectra of the essential oils of garlic and onion were similar and showed straight chain acids, esters, and methylene groups. Clinically, there was no suggestion of cross-sensitivity between onion and garlic.

The effects of some hair oils and unsaturated fatty acids on experimentally induced dermatophytosis.

Antimycotic effect of mustard and coconut oils, oleic and palmitic acids on experimentally produced dermatophytic infection on hairy skin in the guinea pigs was studied. Mean Duration of Infection (MDI) was significantly reduced in all experiments where coconut and mustard oils or unsaturated fatty acid (oleic acid) were used. The significance of these results in realtion to Tinea capitis in humans is discussed.

Elimination of circulating antibodies. Attempts to eliminate antibodies circulating in rabbits using a fraction of normal human epidermis.

Rabbits were immunised with a fraction of normal human epidermis to produce circulating antibodies. In each experiment, half of the immunised rabbits were given a dose of the same antigen intravenously and the changes in the titres of antibodies were recorded. Doses of the antigen used in different experiments varied from 0.09 to 3.5 mg protein per rabor the first 24 h, followed by a secondary rise. Administration of corticosteroids together with the antigen intravenously could check this secondary rise in antibody titre. Repeated intravenous injections of the antigen led to severe anaphylactic reactions, while subcutaneously administered antigen produced no significant effects.
