Correlation between gene expression of aryl hydrocarbon receptor (AhR), hydrocarbon receptor nuclear translocator (Arnt), cytochromes P4501A1 (CYP1A1) and 1B1 (CYP1B1), and inducibility of CYP1A1 and CYP1B1 in human lymphocytes.

The relationships between gene expression of aryl hydrocarbon receptor (AhR), aryl hydrocarbon receptor nuclear translocator (Arnt), cytochromes P4501A1 (CYP1A1), 1B1 (CYP1B1), CYP1A1, and the inducibility of CYP1A1 and CYP1B1 were determined in 32 cultivated human lymphocytes. Cytochrome P450 induction was performed by incubating lymphocytes with benzanthracene. The relative gene expression levels were determined by quantitative real-time RT-PCR assay. We found that gender is an important confounding factor for gene expression in cultivated lymphocytes. AhR, CYP1A1 and CYP1B1 levels in noninduced lymphocytes were significantly higher in female nonsmokers than in male nonsmokers (p < 0.05). Nevertheless, CYP1A1 and CYP1B1 inducibility was lower in female nonsmokers. CYP1A1 inducibility was higher in male smokers than in male nonsmokers (p < 0.05). After controlling for gender and cigarette smoking, AhR levels positively correlated with CYP1B1 levels and CYP1A1 inducibility (p < 0.01 and p = 0.03, respectively). Arnt levels also correlated with CYP1B1 levels in induced lymphocytes (p < 0.01). However, AhR levels were negatively correlated with CYP1B1 inducibility. These data indicate that AhR expression associates with individual variation of CYP1A1 inducibility and CYP1B1 expression in cultivated lymphocytes. Furthermore, gender and cigarette smoking are important confounding factors for gene expression levels in cultivated lymphocytes.     

Enrichment of the antibodies against the C-terminus of Taiwan cobra cobrotoxin using dimeric glutaraldehyde-modified toxin as an immunogen.

The repertoire of antibodies producing by immunizing rabbits with cobrotoxin and dimeric glutaraldehyde-modified cobrotoxin (dGA-cobrotoxin) was analyzed by studying the immunoreactivity of the two antibody preparations toward cobrotoxin, GA-cobrotoxin and recombinant cobrotoxin. The results of enzyme-linked immunoassay revealed that the two antibody preparations exhibited a higher reactivity against their cognate antigen. Moreover, different behavior was observed for the reactivity of the two antibody preparations against GA-cobrotoxin and recombinant cobrotoxin. Notably, distortion of disulfide linkages at the C-terminus resulted in a reduced decrease in the antigenic activity of recombinant cobrotoxin toward anti-cobrotoxin antibodies compared to anti-dGA-cobrotoxin antibodies. Affinity purification of the antibodies against the C-terminus of cobrotoxin revealed that its amount represented 77% and 35.5% of the total anti-dGA-cobrotoxin antibodies and the total anti-cobrotoxin antibodies, respectively. These findings suggest that the antibody preparation elicited by dGA-cobrotoxin enriches the content of antibodies recognizes the C-terminal region of native cobrotoxin.

体外培育牛黄与天然牛黄指纹图谱的比较研究

目的：研究、比较体外培育牛黄与天然牛黄的指纹图谱。方法：利用TOFMS、HPIEJMS技术研究、比较体外培育牛黄与天然牛黄中肽类、胆汁酸类和胆红素类3类成分的指纹图谱。结果：体外培育牛黄与天然牛黄3类成分的指纹基本一致，但各成分间的相对含量有差异。结论：10批体外培育牛黄的指纹图谱有较好的一致性，说明体外培育牛黄的质量稳定。4批天然牛黄的指纹图谱，尤其是胆汁酸类成分的指纹图谱差异明显，说明天然牛黄由于来源不同，导致质量不够稳定.

Successful treatment of azoospermia secondary to ejaculatory duct cyst

Ejaculatory duct obstruction is considered a rare cause of infertility. Two cases are reported of an ejaculatory duct cyst with azoospermia preoperatively diagnosed by transrectal ultrasonography. The diagnosis of ejaculatory duct obstruction in one patient was confirmed by vasography with a combined iodinated contrast medium and methylene blue solution for radiological and direct visualization. Transrectal puncture and contrast filling of the cyst under the transrectal ultrasonographic guidance diagnosed the other patient. On the basis of these findings transurethral unroofing of the cyst was performed successfully. Transrectal ultrasonography facilitates evaluation and treatment of azoospermia caused by ejaculatory duct obstruction and may minimize the need for more invasive studies in such cases.
