[Ocular herpes. Therapeutic aspects (author's transl)].

The range of treatment proposed for ocular herpes regularly widens. In addition to the harmful effects of the herpes virus itself, there are local immunological mechanisms which render the use of antiviral substances all the more difficult. Those currently available (5 iodo 2'deoxyuridine, vidarabine, trifluorothymidine) are certainly of the greatest value in superficial forms but have little effect upon deep seated stromal and uveal involvement. In addition, they are toxic to the corneal epithelium. At all events, they offer treatment during acute exacerbations and cannot prevent recurrences. Treatment should thus often consist of corticosteroids and antiviral agents in alternation and the solution is sometimes to be found in the combined use of these two substances. Surgery is above all indicated in the treatment of the sequelae of ocular herpes, the results of operations performed during acute phases being less definite.

[Aflatoxin inactivation after ammonia treatment. In vitro studies on detoxified peanut meals].

The maximum allowable tolerance of aflatoxins in animal feeds is becoming lower and lower, and it is obvious that the fairly high level of aflatoxin B1 found in almost all peanut meals in recent years restricts this protein source for use in the diets of most animal species. Among the different chemical methods for aflatoxin inactivation, treatment by gaseous ammonia under a pressure of 2 to 3 bars, appears a very attractive solution because it may be achieved by a fairly easy and rapid procedure. This treatment markedly reduces--up to 95 p. 100--the aflatoxins content of the meal. An increase in the nitrogen content, mainly in the non protein form, is observed. Ammoniation has no adverse effect on in vitro pepsin digestibility and even improves the sensitivity of the meal towards proteases. It slightly reduces protein deamination in the artificial rumen and nitrogen solubility in a buffer solution at pH 7,5; these effects seem to be favourable for the utilization of the treated meals by rumiinants. The amino acid compostion of the meal is not significantly changed, particularly with regard to total and available lysine. However, cystine undergoes partial destruction; but this loss could be counterbalanced by a supply of synthetic methionine.

Prospectively randomised trial of proximal gastric vagotomy either with or without pyloroplasty in treatment of uncomplicated duodenal ulcer.

A consecutive series of 100 men with uncomplicated duodenal ulcer was randomly divided into two groups: one group of 52 underwent proximal gastric vagotomy (PGV), the other group (48) underwent PGV with pyloroplasty (PGVP). Preoperative peak acid output (PAOP) was measured in all patients. Those with a higher preoperative PAOP were significantly more likely to develop recurrent ulceration. Three patients developed recurrent ulceration after PGV and seven after PGVP. Dumping was both more common and more severe after PGVP than PGV. An overall satisfactory result was achieved in 92% after PGV and 81% after PGVP. We conclude that combining pyloroplasty with PGV has no appreciable advantages.
