B. hominis (Blastocystis hominis short Bh) in the last 20 years has been valued by people with diarrhea-related human parasitic protozoa. In our country, has as its emerging infectious diseases caused by the disease , people generally Blastocystis protozoal disease was sporadic, but in Southern Chongyi County occurred in 1996 outbreak . 2002 students in our hospital infection rate was 10.09% Bh (426/43) . We have those infected with metronidazole treatment, 3 months later most of the negative conversion results are poor, and easy to relapse. Another study shows that metronidazole is teratogenic and carcinogenic effects . Pomegranate root bark of the reported acid, astringent taste, with astringent intestinal bleeding, the effect of pesticides . The main treatment of bacillary dysentery, amoebic dysentery and a variety of infectious diseases. Picrorhizae insecticidal efficacy of such a detoxification . To provide, develop new herbal insect antigens experimental data, we used nine kinds of Chinese herbal medicine in vitro killing effect of Bh. Are reported as follows.
1.1 Bh strains strains isolated from Department of Gastroenterology, Affiliated Hospital of Gannan Medical College, pediatric patients with faeces (36 ± 0.5) ℃ common anaerobic incubator, passaged every 3 days 1, a total of 20 times passaged medium.
1.2 Drug test drug (purchased from the hospital pharmacy in hospitals and the local subsidiary of pharmaceutical company retail outlet), all for the book, clearing and detoxifying Chinese medicine and insecticide effects of Chinese herbal medicine.
1.3 Locke's egg medium serum (Locke Egg Serum, LES) two-phase medium , into a 30 ° bevel 90 ~ 100 ℃ oven for home heating solidification made. Before switching to each tube add 5 ml Rockwell liquid, sterile 14% inactivated newborn calf serum (purchased from Hangzhou, China, holly leaf Biological Engineering Co., Ltd.) and basic antibiotic solution (0.4% ampicillin, 0.1% chain ADM, 0.000 6% amphotericin B) can switch species.
2.1 Preparation of the nine kinds of Chinese herbal liquid (dry drug) of the 10 g, were loaded into 250 ml triangular flask, 50 ml distilled water in each home, soaked overnight, then put into 80 ℃ water bath in the hot dip 4 h. Filter to remove residue, filtrate were concentrated with a slow fire to the liquid concentration of 1,4,6,8. 3 000 r / min centrifugation 10 min, the supernatant obtained, filtration sterilization, adjust the osmotic pressure, and placing sterile bottle , 4 ℃ save backup.
2.2 The optical microscope for each preparation of four herbs drug concentration group, respectively, 0.1,0.4,0.6,0.8 g / ml, while no drug control group design. Remove the 36h culture of B. hominis culture tubes, respectively, from cultured basal layer suction equal 20 μl drops of parasite suspension in a slide, add coverslip microscope. Blood cell count observation register to do to calculate the number per mm3 contained in the worm. Each tube worms concentration of about 1 × 103 个 / ml, then adding different concentrations of liquid 1ml each culture tube, place (36 ± 0.5) ℃ in an incubator. 2,4,8,12 h culture were drawn after the droplet slides examined each tube worms, worms with active high power microscope to calculate worm mortality. After 24 h, mortality was 100% of the test tube transfer species, (36 ± 0.5) ℃ cultured for 48 h, see if there Bh survival, all the experiment was repeated 3 times.
The same action time, pomegranate root bark, Picrorhiza, berberine, Melia Paper Group Bh mortality rate higher than the control (P <0.01), and larvae mortality increased with increasing drug concentration (P <0.01); the same drugs concentration, with the action time, Bh mortality gradually increased (P <0.05). High magnification, the role of pomegranate root bark group after 2 h, 1,4,6,8 g / ml concentration group all worms apoptosis, morphological change significantly. Most worms membrane edge blur, body sag cracking (Figure 1). The role of picrorhizae group 2 h after the 1,4 g / ml concentration group all induce parasite cysts (Figure 2). 8 h, the role of 6,8 g / ml concentration group worms all died. Then the root bark of pomegranate and Picrorhiza species of insect culture medium group transferred 24 h, showed no Bh growth. Neem bark, Coptis effect on the insect body is not strong, and Weng, pumpkin seeds, make a gentleman, betel nut, matrine on B. hominis had no effect. The results in Table 1. Worms intact control group (Figure 3).

Pomegranate root bark of Psidium guajaual medicine is deciduous shrub or small tree, intestinal diarrhea with astringent to stop bleeding, the efficacy of insecticide detoxification. Commonly used in clinical treatment of Jiu Li, Chronic Diarrhea, hematochezia, rectal prolapse, bleeding, vaginal discharge, abdominal pain embolism product insects . Recent studies show that there is a wide range of leather pomegranate root bacteria and inhibition of influenza virus . Scrophulariaceae Picrorhiza is the growth of low vegetation and plants for many years, is a commonly used medicinal herbs. With heat, dampness, eyesight, Bugan, Yidan, insecticidal effectiveness. This study confirmed that pomegranate root kill leather obvious role of B. hominis, 0.1 g / ml concentration of the drugs were 2 h with the killing of the Bh and decomposition. Picrorhizae worms into the capsule can be induced early, with the increase in drug concentration, treatment time, Bh increased mortality, that is insecticidal effects and drug concentrations and times of a positive correlation. 0.6 g / ml concentrations of drugs hominis 8 h all of apoptosis. And after switching to no Bh growth. Select the appropriate drug concentration and time were observed by light microscopy is a key mechanism of drug action. Accordingly, this experiment used a low concentration of the root bark of pomegranate liquid, body fast apoptosis, cleavage, demonstrated the killing effect of the root bark of pomegranate, but can not observe the parasite surface membrane damage dynamic process, its exact mechanism worthy of further study. Low concentration of liquid to fully observe picrorhizae worms by the drug effects of changes in trophozoites induce capsule first and then the high concentration of drugs after the larvae quickly die. Coptis, Melia Paper on the role of B. hominis is not strong, and Weng, pumpkin seeds, make a gentleman, betel nut, matrine on B. hominis had no effect, so that the root bark of pomegranate, water extract of Picrorhiza have to kill buds hominis role. Pomegranate root bark, Picrorhiza is a common Chinese herbal medicine, China's resource-rich, low cost and low toxicity. The experiment for the use of pomegranate root bark, Picrorhiza development of new high-performance topical and oral anti-toxicity drugs hominis basis.
