[Protective effect of oleanolic acid liposomes on cisplatin-induced oligoasthenospermia in mice].

Objective: To study the protective effect of oleanolic acid liposomes (OA-Lips) on cisplatin-induced oligoasthenospermia (COAS) in mice.

Methods: Sixty ICR mice were randomly divided into a normal control, a COAS model control, a positive control and a low-, a medium- and a high-dose OA-Lips group. The animals in the low-, medium- and high-dose OA-Lips and positive control groups were given intragastrically OA-Lips solution at 25, 50, and 100 mg/kg/d and vitamin E at 50 mg/kg/d, respectively.

[Comparative studies on different methods for laboratory diagnosis of pertussis].

Objective: To confirm the clinically suspected pertussis cases(<1 years old) through laboratory methods.

Methods: From December, 2011 to December, 2012, patients with clinically suspected pertussis from Xi'an Children's Hospital were sampled, with their nasopharyngeal swabs collected, blood samples cultured and pertussis toxin IgG detected by PCR.

Results: were analyzed, using SPSS 16.

[Analysis of the genotype of intraspecies of common Mycobacteria based on 16S-23S rRNA gene internal transcribed spacer sequences].

Objective: To analyze the genotypes of intraspecies of common mycobacteria.

Methods: The genotypes of 94 strains of mycobacteria from DSMZ, as compared with 12 reference strains, were studied by 16S-23S rRNA internal transcription space (ITS) sequence analysis.

Results: The sequencing of 16S-23S rRNA ITS of the 106 strains of common mycobacteria were completed.
