We evaluated an anti-inflammatory enzyme drug Danzen (Serrapeptase) Takeda Chemical Industries, Ltd.) on 70 patients complaining of breast engorgement These patients were randomly divided into 2 groups, a treatment group and a placebo group. A single observer, unaware of the group the patients were in, assessed the severity of each of the symptoms and signs of breast engorgement before treatment was commenced, and daily for 3 days, during which therapy was administered. Danzen was noted to be superior to placebo for improvement of breast pain, breast swelling and duration and while 85.7% of the patients receiving Danzen had "Moderate to Marked improvement, only 60.0% of the patients receiving placebo had a Similar degree of improvement. "Marked improvement was found in 229% of the treatment group and 2.9% of the placebo group. These differences were statistically significant (P less than 0.05), No adverse reactions were reported with the use of Danzen (Serrapeptase). Danzen (Serrapeptase) is a safe and effective method for the treatment of breast engorgement.

Using a quantitative standardized procedure, the swelling of the ankle produced by supination trauma was measured. In the 66 patients with fresh rupture of the lateral ligament treated surgically at our Department between December 1986 and April 1987, a prospective study of the effect of serrapeptase (Aniflazym) on postoperative swelling and pain was carried out in 3 randomized groups of patients. To the group receiving the test substance, the swelling had decreased by 50% on the third post-operative day, while in the other two control groups (elevation of the leg, bed rest, with and without the application of ice) no reduction in swelling had occurred at that time. The difference is statistically significant (p = 0.013). Decreasing pain correlated for the most part with the reduction in swelling Thus, the patients receiving the test substance more) rapidly became pain-free than did the control groups. On the basis of these results, serrapeptase would appear to be an effective preparation for the port-operative reduction of swelling, in comparison with the classical conservative measures for example, the application of ice.

A multi-centre, double-blind, placebo-controlled trial was carried out to investigate the clinical efficacy of the anti-inflammatory enzyme serrapeptase in a total of 174 patients who underwent Caldwell-Luc antrotomy for chronic emphysema. Eighty-eight patients received 10 mg serrapeptase 3 times on the day before operation, once on the night of the operation and 3 times daily for 5 days after operation, the other 86 received placebo Chanes in buccal swelling after operation were observed as a parameter of the response to treatment. The degree of swelling in the serrapeptase-treated patients was significantly less than that in the placebo-treated patients at every point of observation after operation up to the 5th day (p less than 001 top less than 0.05). Maximal swelling throughout all the post-operative points of observation was also significantly smaller in size in the serrapeptase-treated group than in the placebo-treated group. No side effects were reported.

A sensitive sandwich enzyme immunoassay (e.i.a) for serrapeptase (TSP), an orally available anti-inflammatory proteinase, was established using affinity-purified anti-TSP rabbit IgG and its Fab fragment conjugated with horseradish peroxidase as the first and the second antibodies respectively TSP in the plasma was determined by the e.i.a. after its oral administration (100 m/kg) to rats. The peak concentration was observed between 30mm and 2 h after administration. TSP in the plasma samples was trapped in a microtitre plate coated with the affinity-purified anti-TSP rabbit IgG. and the hydrolysis of a synthetic fluorogenic substrate, butoxycarbonyl-Glu(benzyloxy)-Ala-Arg-4-methylcoumaryl-7-amide, by the trapped TSP was fluorometrically measured (proteinase  assay. The values obtained by the e.i.a. and those obtained by the proteinase assay correlated well for various plasma samples. These results indicate that orally administered TSP was absorbed from the intestinal tract and transferred into the circulation in an enzymically active form.
