ABSTRACT
Objective@#To prepare monoclonal antibodies against pneumonia serotype 33F polysaccharides (Pn33Fps) and hepatitis B virus (HBV) surface proteins (HBs) by using the conjugate of Pn33Fps and HBs as antigen.@*Methods@#The conjugate of Pn33Fps and HBs was used as antigen to immunize mice with different immune doses, different immune procedures and different immune sites. Mouse spleen cells with higher antibody level after immunization were isolated and fused with SP2/0 myeloma cells. The hybridoma cells were screened specifically with Pn33Fps or HBs to prepare corresponding monoclonal antibodies.@*Results@#Serum antibodies against Pn33Fps and HBs were induced by immunizing mice with the conjugate. Monoclonal cell lines capable of continuously expressing antibodies against Pn33Fps or HBs were obtained. It has been proved that the recovery rates of samples of Pn33Fps and HBs prepared in three batches tested with ascites monoclonal antibodies prepared by these two monoclonal cell lines were between 95% and 105%.@*Conclusions@#Monoclonal antibodies against Pn33Fps and HBs could be prepared simultaneously by immunizing mice with the conjugate of Pn33Fps and HBs and used for the quantitative detection of Pn33Fps and HBs.

Mouse spleen cells with higher antibody level after immunization were isolated and fused with SP2/0 myeloma cells. The hybridoma cells were screened specifically with Pn33Fps or HBs to prepare corresponding monoclonal antibodies. Results Serum antibodies against Pn33Fps and HBs were induced by immunizing mice with the conjugate. Monoclonal cell lines capable of continuously expressing antibodies against Pn33Fps or HBs were obtained. It has been proved that the recovery rates of samples of Pn33Fps and HBs prepared in three bat-ches tested with ascites monoclonal antibodies prepared by these two monoclonal cell lines were between 95％ and 105％. Conclusions Monoclonal antibodies against Pn33Fps and HBs could be prepared simul-taneously by immunizing mice with the conjugate of Pn33Fps and HBs and used for the quantitative detection of Pn33Fps and HBs.
ABSTRACT
This study was aimed to explore the action mechanism of massage treatment in combination with small needle knife to cervical spondylotic vertebral arteriopathy (CSA). A total of 400 CSA patients were randomly divided into four groups, which included group A (medicine treatment group), group B (small needle knife therapy group), group C(massage treatment group) and group D (small needle knife combined with massage treatment group). The observation was given on the average blood flow velocity (Vm), pulsatility index (PI) and treatment efficiency of ver-tebral artery(VA) and basilar artery (BA) before and after treatment among 400 cases using transcranial doppler (TCD). The results showed that TCD detection of Vm of VA and BA in group B, C and D were obviously improved after treatment; and the PI of them was close to normal. The total effective rate of group A was 66.0%, 78.6% in group B, 80.2% in group C, and 96.0% in group D. It was concluded that the treatment by massage in combination with small needle knife therapy of vertebral artery type of cervical spondylosis had a clear effect. Its mechanism may be related to the improvement of Vm and PI of vertebral basilar artery.
