RESUMEN
OBJECTIVE: To observe the effect of Mienangling (MNL) in treating cysticercus cellulosae in vitro. METHODS: The changes of cysticercus cellulosae treated in vitro with the MNL extracts, praziquantel (PQT) and albendazole (ALB) were studied under the transmission and scanning electron microscopes. RESULTS: Under the scanning electron microscope, the authors can see that all of the cysticercus's scoleces did not grow in the MNL and PQT groups, cyst walls shrivelled, tegument's ectoplasts were damaged, microtriches's ultrastructures were not clear or exfoliated, some corpuscular matter densely was distributed in the surface; 46.7% of cysticercus cellulosaes in the ALB group had been excystated, the rostellar hooks of rostella developed normally, four sucker's surface wrer hollow, the necks were eroded, and grooves of sonite disappeared. Under the transmission electron microscope, we can see that the tegument, basement membrane, muscular layer and parenchyma in the groups of MNL and PQT were all clearly damaged, but the harmful effect of MNL to parenchyma's nerve cords is more serious than the PQT. The damage of all layers of the cysticercus cellulosae in the ALB group is smaller in degree than the MNL and the PQT. CONCLUSION: The MNL has marked damaging effect to cysticercus cellulosae.

UNLABELLED: Clinical double blind study in treating 153 intractable ulcerative colitis with Chinese medicinal herbs was conducted, the patients were randomly assigned to three groups. Group I is administered with Jian Pi Ling (JPL) tablet with retention-enema of Radix Sophorae Flavescentis and Flos Sophora (RSF-FS) decoction per night, group II with salicylazosulfapyridine (SASP) and retention-enema of dexamethasone, group III with placebo and retention-enema of decoction as that in group I. After 90 days every patients were checked by means of fibro-enteroscope, pathologic and immunologic parameters. THE RESULTS: the curative rates of group I, II, III, were 53.1%, 27.7% and 19.0%, the total effective rates were 85.9%, 59.6% and 45.2% respectively. By comparison among groups, the efficacy of group I was the best (P < 0.01). The check of T and B lymphocyte subpopulation showed the B lymphocyte of group I markedly decreased, OKT3 and OKT8 obviously increased, the ratio of OKT4 and OKT8 approached normal value. The amount of IgG, IgM, C3 increased abnormally, decreased dramatically after medication, while those of group II and III have not changed significantly. The bacteriostatic test in vitro showed the bacteriostatic effect of RSF-FS on pathogenic B. coli, Shigella dysenteriae and Staphylococcus aureus was the best, that of solution Jian Pi Ling the next, that of SASP was the least effective. Therefore, the principle and method of group I seems to be the best therapeutic programme.

In this paper, the ulcerative colitis model of rats with immuno-method was reported and the mechanism of using Jianpiling for the treatment of ulcerative colitis was studied. The rats of experimental group were subdivided into 3 subgroups (A, B and C), 15% Jianpiling suspension was given to rats in subgroup A per os, 15% Bupi-Yichang Pill to rats in subgroup B per os, 4.5% SASP suspension to rats in subgroup C, and same amount of saline to rats in the control group. The therapeutic results showed that the anti-diarrhia, anti-infection and repairing function of tissue by Jianpiling were obviously better than those of Bupi-Yichang Pill and SASP. Serological exams also showed that Jianpiling was much better than other therapeutic groups in increasing nonspecific cellular immunity and lowering level of antibody against large intestine and IgG. These results suggested that the mechanism of Jianpiling on ulcerative colitis was realized by increasing cellular immunity, inhibiting humoral immunity and promoting immune modulation.
