A Relationship between Uterine Cervical Cytopathology and Histopathology in Mongolia

Objectives: This study aimed to evaluate the correlation between uterine cervical squamous cell abnormalities by conventional cytology and corresponding histopathology, and to assess the accuracy between them. Methods: A total of 192 cytological smears of patients with squamous cell abnormalities who underwent colposcopy examination from April – December 2015 were included in this study. The final agreement between cytology and histopathology was defined by the evaluation of histology as a golden standard. Results: The agreement between cytology and histopathology evaluation was 65.6%, and the discrepancy was 33.6% (k=0.512). When the classes of cytology were evaluated for accuracy, it was discovered that NILM* had a higher sensitivity of 77.0%, a specificity of 87.0%, a false positive of 23% and a false negative of 13.0% (k=0.711). Among the LSIL cases a sensitivity was discovered of 39.0%, a specificity of 82.7%, a false positive of 61.0% and a false negative of 17.3% (k=0.392. However, in HSIL sensitivity dropped to 37.8%, specificity increased to 91.6%, false positive were 62.0% and false negative were 8.4% (k=0.501). Conclusion: The agreement for diagnosis of uterine cervical cytology and histopathology was 65.6% (n = 126) and the discrepancy was 33.6% (n = 64) (p = 0.001). The correlation between cervical cytology and histopathology remained moderate (kappa=0.512). Thus, it is proposed that an appropriate quality control system for the cytopathological confirmation may contribute to the further detection and treatment for uterine cervical cancer in Mongolia

Chemical composition and antimicrobial activity of essential oil from Pyrethrum pulchrum Ledeb.

The chemical composition and antimicrobial activity of the essential oil from the aerial parts of Pyrethrum pulchrum Ledeb. were investigated. Dried plant material was hydro-distillated yielding 0.1% of essential oil. The oil was analyzed by GC-MS techniques. Fifty-five compounds were identified representing 99.7% of the total oil composition. Camphor was the predominant compound (33.9%) followed by linalool (21.1%) and α-pinene (9.0%). The antimicrobial activity of the oil was determined using the disk diffusion method against Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus and Enterococcus faecalis), Gram-negative bacteria (Pseudomonas aeruginosa and Escherichia coli), Mycobacterium vaccae and fungi (Candida albicans, Sporidiobolus salmonicolor and Penicillum notatum). The essential oil of P. pulchrum displays an intermediate activity against selected bacteria

Artemisioside, a new monoterpene glucoside from the aerial parts of Artemisia ordosica (Asteraceae).

A new monoterpene glucoside, artemisioside, was isolated from the aerial parts of Artemisia ordosica Krasch. (Asteraceae). The chemical structure was elucidated from physicochemical data and by the application of Klyne\u27s rule.A new monoterpene glucoside, artemisioside, was isolated from the aerial parts of Artemisia ordosica Krasch.
