In this study, transgenic tobacco plants were generated to express anti-colorectal cancer large single chain (LSC) antibody CO17-1A (LSC CO) and LSC CO tagged with the endoplasmic reticulum (ER) retention signal KDEL (LSC COK). The LSC antibodies were constructed by linking the C-terminus of variable region (VL) of the light chain (LC) to the N-terminus of the heavy chain (HC) of mAb CO17-1A with a linker peptide. Reverse-transcription PCR (RT) and immunoblot analyses showed that the LSC CO17-1AK expression level was higher than LSC CO17-1A in plant. In glycosylation analysis, oligomannose type glycan form was observed in LSC COK and plant-specific α(1,3)-fucose was observed in LSC CO. Binding activity of both LSC CO17-1A and LSC CO17-1AK to human colorectal cancer cell lines SW480 and SW620 were confirmed using indirect cell enzyme-linked immunosorbent assay (ELISA). In indirect cell ELISA, the LSC antibodies had a higher binding activity than full-size mAb CO17-1AK. In surface plasmon resonance (SPR) assay using epidermal cell adhesion molecule (EpCAM) highly expressed on the human colorectal cancer cells, both LSC antibodies showed a similar binding activity to the full-size mAb CO17-1A. These results indicated that LSC antibodies with functional binding activities to human colorectal cancer cells and EpCAM protein were successfully expressed in the transgenic tobacco plant.

Purpose: To assess knowledge, attitudes and cervical cancer screening behavior of Bangkok Metropolitan women. Materials and Methods: Thai women, aged 25-to-65 years old, having lived in Bangkok for 5 years or more were invited to participate in the study. After signing informed consent, all women were asked to complete a self-questionnaire (Thai language) with literate assistance if needed. The questionnaire was divided into 3 parts: (I) demographic data; (II) knowledge about cervical cancer screening; and (III) behavior and attitudes, towards cervical cancer screening. Adequate screening was defined as women who had ${\geq}$two cervical cancer screening tests except women aged 25-30 years who may have only one screening, and the last screen was within 5 year or had had regular screening. Results: Of 4,339 women, there were 1,857 (42.8%) with adequate screening and 2,482 (57.2%) with inadequate screening. Significant factors associated with inadequate screening included age < 45 years, pre-menopausal status, family monthly income <625 USD, no reported sexual intercourse, nulliparous, no knowledge, lack of awareness and poor attitudes. Three major reasons provided by women for inadequate screening were no symptoms (54.4%), fear of pain (33.2%), and embarrassment (34.6%). Conclusions: Personal features, knowledge, and attitudes influence screening behavior of Bangkok Metropolitan women. The three most common reasons of women for not undergoinging screening are no symptoms, fear of pain, and embarrassment. These factors should be the focus of attention to improve coverage of cervical cancer screening in Bangkok.

Background: Many strategies are required for cervical cancer reduction e.g. provision of education cautious sexual behavior, HPV vaccination, and early detection of pre-invasive cervical lesions and invasive cancer. Basic health data for cervical cytology/ HPV DNA and associated factors are important to make an appropriate policy to fight against cervical cancer. Aims: To assess the prevalence of abnormal cervical cytology and/or HPV DNA and associated factors, including sexual behavior, among Bangkok Metropolitan women. Materials and Methods: Thai women, aged 25-to-65 years old, had lived in Bangkok for ${\geq}5$ years were invited into the study. Liquid-based cervical cytology and HPV DNA tests were performed. Personal data were collected. Main Outcomes Measures: Rates of abnormal cytology and/ or high-risk HPV (HR-HPV) and factors associated with abnormal test (s) were studied. Results: Abnormal cytology and positive HR-HPV were found in 6.3% (279/4442 women) and 6.7% (295/4428), respectively. The most common abnormal cytology was ASC-US (3.5%) while the most common HR-HPV genotype was HPV 16 (1.4%) followed by HPV 52 (1.0%), HPV 58 (0.9%), and HPV 18 and HPV 51 at equal frequency (0.7%). Both tests were abnormal in 1.6% (71/4428 women). Rates of HR-HPV detection were directly associated with severity of abnormal cytology: 5.4% among normal cytology and 13.0%, 30.8%, 40.0%, 39.5%, 56.3% and 100.0% among ASC-US, ASC-H, AGC-NOS, LSIL, HSIL, and SCC, respectively. Some 5% of women who had no HR-HPV had abnormal cytology, in which 0.3% had ${\geq}$ HSIL. Factors associated with abnormal cytology or HR-HPV were: age ${\leq}40$ years, education lower than (for cytology) or higher than bachelor for HR-HPV), history of sexual intercourse, and sexual partners ${\geq}2$. Conclusions: Rates for abnormal cytology and HR-HPV detection were 6.3% and 6.7% HR-HPV detection was directly associated with severity of abnormal cytology. Significant associated factors were age ${\leq}40$ years, lower education, history of sexual intercourse, and sexual partners ${\geq}2$.
