ABSTRACT
The direct effects of cholera enterotoxins from classical V. cholerae (C-569-B) and El Tor (C-201) on the segmental resistance of the mesenteric and portal circulation were studied in dogs using the constant flow perfusion method. Compared to histamine, a vasodilator, and norepinephrine a vosoconstrictor, whose vasoactive effects on the canine mesenteric circulation using the same method have been established, the cholera enterotoxins are not vasoactive agents. Both toxins that were shown to produce the usual cholera effect in rabbit ileal loops had no effect on the total (RT) , small vessels (RSV), and venous (RV) resistances of the canine mesenteric circulationThe results of the present experiments are in agreement with the observation and view that the intestinal fluid loss in cholera has no vascular component. These findings do not support the theory that the intestinal fluid production in cholera is produced by filtration of fluid from the blood through filtration channels in the intestinal mucosa.

ABSTRACT
A report of a total of 285 cases of superficial mycoses are herein presented. It was noted that the most common superficial mycoses in the Philippines were dermatophyte infections constituting 52.6% followed by Candidiasis (Moniliasis) which was 41.0%Of the various dermatophytes isolated from 150 cases of ringworm infection, T. rubrum was found to be the most common constituting 40.0% followed by T. mentagrophytes 18.7%, M. canis 16.7%, T. tonsurans 12.7%, M. gypseum 5.3% and E. floccosum 4.0%. T. concentricum stands as the least frequent cause of superficial mycoses among the dermatophytesA brief description of the clinical and mycologic aspects of superficial mycoses is likewise presentedThe use of KOH with Parker superchrome blue black ink as a practical method in the demonstration of fungus elements in clinical materials is also included.
