ABSTRACT: To evaluate the effect of Jieze No. 1 Gel (JZ1) on the inner environment of vagina through observing its influences on vaginal levels of lactobacillus, glycogen and lactoferrin in mice.
One hundred female Kunming mice were randomized into 5 groups, the blank control (BC) group, the blank gel (BG) group, and the three JZ1 treated groups. They were treated via vagina with saline, matrix gel, high (2 mg/microL), middle (1 mg/microL) and low (0.5 mg/microL) dose JZ1 respectively in volume of 20 microL, 72 h after being subcutaneously injected with physiological estradiol benzoate (E2) 2 microg. The 24 h and 72 h living lactobacillus in vaginal lavage fluid cultures were counted, the content of glycogen and the expression of lactoferrin in vaginal tissue were measured.
No significant difference was found between the BC group and the three JZ1 treated groups in terms of lactobacillus-CFU, glycogen content and lactoferrin expression, and these indices detected at 24 h were not different to those detected at 72 h in the groups treated with various doses of JZ1 respectively (P > 0.05).
Once application of JZ1 shows no effect on levels of lactobacillus, glycogen, and lactoferrin expression in the vagina of mice.

ABSTRACT: To observe the clinical therapeutic effect of Jieze No. 1 ( I ) on cervicitis caused by ureaplasma urealyticum and its inhibitory effect on ureaplasma urealyticum (Uu) in vitro.
A total of 393 patients suffering from cervicitis induced by ureaplasma urealyticum without other complications were randomly assigned to 3 groups, the combined treatment group: 140 patients treated with Chinese herbs Jieze No.1 by vaginal lavage, 30 min each time, once a day for 10 consecutive days and oral administration of Azithromycin, 1.0 g once every 72 h for three times; Jieze group: 115 patients were treated with Jieze No.1 alone by vaginal lavage, 30 min each time, once a day for 10 consecutive days; and the Azithromycin group: 138 patients were treated with oral administration of Azithromycin, 1.0 g once in 72 h for three times. All the patients were treated for 1 therapeutic course and condom were used for contraception during the treatment course. The Uu patients were examined again after 21 days of treatment. The therapeutic effect on cervicitis was observed. The experimental study of Jieze No. 1 on the Uu strain separated from the secretion of the urogenital tract was also observed. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the Uu were investigated.
The total effective rate of the combined group was 85.3%, showing a significant difference compared with the Jieze group (67.8%) and the Azithromycin group (60.3%, both P<0.01). There was no statistical significance between the latter two groups (P>0.05). The clearing rate of Uu in the combined group was 78.4%, that of the Jieze group was 60.9% and the Azithromycin group was 47.9%. The combined group also showed a significant difference in comparison with the other two groups (all P<0.01). Especially for the drug-resistant strain, the clearing rate of Uu reached 48.1% in the combined group, 42.1% in the Jieze group, and 16.1% in the Azithromycin group, respectively. The clearing rate of Uu for the drug-resistant strain in the former two groups had significant differences in comparison with the latter (P<0.01, P<0.05), while there was no significant difference between the former two (P>0.05). The range of MIC and MBC of Jieze No. 1 to the drug-resistant strain of Uu was 15.62-250.00 mg/mL. To the non-drug-resistant MIC and MBC strain, it was 15.62-125.00 mg/mL. For the drug-resistant strain, MIC(50) was < or = 31.25 mg/mL, MBC(50) was < or = 62.50 mg/mL, MIC(90) was < or = 125.00 mg/mL and MBC(90) was 250.00 mg/mL. For the non-drug-resistant strain, MIC(50) was < or = 31.25 mg/mL, MBC50 was< or = 62.50 mg/mL, MIC(90) was< or = 62.50 mg/mL and MBC(90) was < or = 125.00 mg/mL.
Jieze No.1 combined with Azithromycin can effectively treat cervicitis caused by Uu. The laboratory study confirms that Jieze No. 1 has an inhibitory effect on ureaplasma urealyticum strain. It has a remarkably effective therapeutic effects on drug-resistant strains, which is worthy of further research.

ABSTRACT: The model of vaginal candidiasis in Kunming mice was constructed in order to search for the optima construction conditions and provide an economic animal model of Candida albicans (C. albicans) vaginitis. Estrogen benzoate (E2) was given to mice at different concentrations ranging from 0.0 to 0.05 mg/mouse (4 levels) beginning 72 h prior to vaginal inoculation, then mice were inoculated intravaginally with various concentrations of stationary-phase C. albicans blastoconidia (ATCC90028) (5 levels) in 20 microL of phosphate-buffered saline (PBS) in each E2 level. General state, scores of genital pathology, the hyphae and vaginal fungal burden (CFU) in vaginal lavage fluid, the hydrops rate of uterus and vaginal tissues for pathological section in mice were observed and obtained at day 2, 4, 7, 14 and 21 after inoculation. The results showed the infection rate in mice was related to the dosage of E2 and concentration of C. albicans blastoconidia. Additionally there was better cross-effect between the two treated factors. The infection rate was about 80% on the day 4, and could reach 100% on the day 7 until the end of experiment after inoculated intravaginally in groups of E2I3, E2 0.025 mg/mouse injected hypodermically and inoculated intravaginally with 5 x 10(4) C. albicans blastoconidia, and large amount of hyphae and blastoconidia could be observe in superficial layer tissue and canal of vaginal by PAS. From the results in our experiment it was concluded that E2I3 was the optima construction condition in kunming mice.

ABSTRACT: Spermicidal effect of Jieze No. 1 (JZ1) in combination with nonoxynol-9 (N-9) was examined in vitro. The minimum spermicidal concentration of JZ1 decoction, N-9 and their mixture solution in 20 s and 3 min were examined by improved spermicidal test of Sander-cramer in vitro. The percentages of progressively moving spermatozoa, moving spermatozoa and viable spermatozoa were also observed 20 s, 3 min and 30 min after the addition of the liquid medicine. Our results showed that sperms did not recover their activities in a revival test when the minimum spermicidal concentration of either JZ1 decoction, or N-9, or the mixed solution of the two agents, was used. N-9 (JZ1 in the mixed group) showed significant differences in the percentages of progressively moving spermatozoa, moving spermatozoa, and visible spermatozoa in 20 s, 3 min, and 30 min, when compared with N-9 alone (P < 0.01). We are led to conclude that JZ1 decoction can improve N-9 spermicidal action in vitro, and when used in combination with N-9, it has synergic effect.
