54 cases of hydatidiform mole pregnancy were studied at the Department of Gynecology and Obsterics of the Central Hospital from June 2000 to July 2001, in comparing with 124 cases of normal immature delivery of living neonate. A high rate of clinical symptoms were noted including vaginal hemorrhage in the first trimester, a more unterine height than in normal fetal age, anemia, severe vomit, pre-eclampsia, hyperthyroidism, luteino-adenoma cyst of > 5 cm diametre. There is a positive relation between vaginal bleeding, uterine height before the curettage and the state of luteino adenoma cyst with Chorio complication. Related factors of hydatidiform mole pregnancy were nutritional status, occupation, age, history of abortment and water source hygiene.

Aims: The objective of the study was to isolate bacteriophages and conduct a comprehensive analysis of their potential against Xanthomonas oryzae pv. oryzae (Xoo) strains in the Mekong Delta, Vietnam. Methodology and results: Twelve Xoo strains were isolated from rice fields located in the Mekong Delta, Vietnam. Among these strains, three strains Xoo L019, L020 and L024, showed the highest disease index of bacterial blight. Four phages specific to Xoo were isolated from soil, water and leaf samples, and their morphologies were determined. In a test against 12 Xoo strains, phage L541, MLA23 or W41 could infect 10 of the 12 Xoo strains, while phage LBH01 could infect 8 of the 12 Xoo strains. The stability of the phages to pH, organic solvents, UV-A and UV-B was also evaluated. Conclusion, significance and impact of study The initial characterization of the phages indicates their potential as biocontrol agents against bacterial blight in rice. The study is one of the very first studies about Xoo phages in rice in Vietnam.
