Thirty-seven patients with external gastrointestinal fistulas were treated with a combination of total parenteral nutrition (TPN) and somatostatin (ST). There was a significant fall in fistula output within the first day of treatment (p less than 0.001).

Unilateral topical application of progesterone to the female hamster flank organ topically treated with testosterone propionate resulted in localized inhibition of both in vitro 14C-lipogenesis and in vitro conversion of 14C-testosterone to 5 alpha-reduced radio-metabolites. Topical progesterone did not inhibit in vitro 14C-lipogenesis in the male hamster flank organ.

Another function of the stratum corneum is to decrease the cutaneous penetration of topical corticosteroids like difluprednate and to modify their bioavailability ('corticosteroid reservoir'). Our data suggest that variations in stratum corneum thickness between subjects explain variation of transepidermal water loss and sensitivity difluprednate, as there is a close relationship between these two parameters.

The results show that a close relationship exists between guinea pig and human responses, with both radiations used, and that man seems to be slightly more sensitive to phototoxic effects of bergamot oil than the guinea pig. This difference of sensitivity necessarily implies the participation of UVA (320--400 nm) in the phototoxic reaction of bergamot oil with solar radiation.
