BACKGROUND:The skin lesions, pathological and immunological characteristics of Nc/Nga mice are consistent with human atopic dermatitis, and as an atopic dermatitis animal model, it has great research value. But there are no reports on the physiological and biochemical parameters of Nc/Nga mice in China. OBJECTIVE:To observe the growth and reproduction and blood physiological and biochemical parameters of atopic dermatitis model of NC/Nga mice METHODS:The data of reproductive performance of NC/Nga mice from the first to the third generation was analyzed, including mean litter size, weaning rate, pregnancy rate and generation interval. The body mass of 60 Nc/Nga mice with 1-56 days old was measured, 30 mice of female and male, then the growth curve was draw. The blood samples from the infraorbital vessels were col ected to detect the blood physiological and biochemical parameters in the mice. RESULTS AND CONCLUSION:The mean delivery interval of Nc/Nga mice was (25.8±3.1) days, mean litter size was (7.5±2.5) mice, mean weaning rate was (97.2±1.2)%, the mean pregnancy rate was (97.0±1.4)%, and there was no significant difference among the three generations of these mice (P>0.05). The body mass of Nc/Nga mice was increased with the time increasing of days, the body mass of the mice was maximal within 1-2 weeks post-weaning, and there was no significant difference in body mass between males and females at 6 weeks post-weaning (P>0.05). Comparison of the blood physiological and biochemical parameters of mice at the same age between males and females showed that the levels of red blood cells and hemoglobin in female mice were significantly higher than those in the male mice;the platelet count in the male mice was significantly higher than that in the female mice (P<0.05);the triglycerides and albumin levels in the female mice were higher than those in the male mice (P<0.05). The results indicate that the gender and age may influence the blood physiological and biochemical parameters of Nc/Nga mice.

Objective To estimate the clinical value of thinprep cytologic test (TCT) in screening cervical lesion. Methods 4234 TCT samples were interpreted according to the Besthesda System (TBS), 272positive cases (ASC-US or above) were taken colposcopic examination and biopsy. Results The coincidence of the results between TCT and biopsy in low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), squamous cell carcinoma (SCC), adenocarcinoma (AC) were 85.71%(12/14), 100 % (20/20), 75 % (3/4) and 100 % (2/2), respectively. The positive rates of over ASC-H by TCT and of over CIN Ⅰ by biopsy were 23.16 % (63/272) and 24.26 % (66/272), respectively. There is no difference between two positive rates (x2 = 0.868, P = 0.581). Conclusion TCT and histopathological diagnosis had a high coincidence, a combination of both can greatly enhance HSIL and cervical cancer and reduce the incidence of missed diagnosis. TCT would be a rapid and convenient method for screening cervical cancer.

AIM To investigate the relationship between sinomenine distribution and its organic toxicology in rats so as to give some pharmacological data for clinical application of sinomenine. METHODS Three kinds of administration plans were designed in the experiment, ie sinomenine was ip administered at the dosage of l50 mg*kg-1 per day, repreat-dosed for 6 wk and suspended the drug for 1 wk after 6wk repeat-doses.At the end of the each administration plan,the animals were sacrificed and their blood and their main internal organs were collected for the purpose of measurement of sinomenine concentration in each sample by HPLC. Meanwhile,the histopathological and serological examinations were also done in the experiments. RESULTS The sinomenine concentration in rats internal organs were in order of liver, heart, lung and brain either in single-dosed treated animals or in repeat-dosed treated animals for 6 wk. However,the concentration of sinomenine could not be detected by HPLC after l wk drug-suspension,the histopathological examination showed that sinomenine at the dosage of l50 mg*kg-l per day for 6wk treatment could slightly damage liver ce11s, dominant1y caused the cell edema,but no any influence on the sero1ogy of liver and kidney. Sinomenine ip could also cause a mild hyperaemia of the rats heart tissues but no any histopathological changes had been observed. In testis tissues no sinomenine had beed detected although the animals were treated by repeat treatment for 6 wk and no any histopathological changes had been found yet. However, Sinomenine could partialy inhibit the sperm vitalities and amount of the dead sperms were a1so augmented. It was similar to in vitro eperiments. These influences of sinomenine on testis could be quickly recovered by drug suspension. CONCLUSION Sinomenine concentration were in order of liver, heart, kidney, lung and brain either in treatment by single dose or by repeat-dose administration. The histopathological changes were only abserved in liver cells of the animals which indicates that it should be in consideration of the liver functions during treatment course of the drug.
