OBJECTIVETooth eruption requires the presence of the dental follicle (DF) around the unerupted tooth. This study is to investigate programmed cell death on human dental follicle cells and changes of programmed cell death under different hydrostatic pressures: 0, 50 and 100 kPa.
METHODSHuman dental follicles from third mandibular molars were surgically removed from adolescents who need for orthodontics treatment after informed content, then trypsinized and cultured. Human dental follicle cells were divided into three groups according to different hydrostatic pressures: 0, 50 and 100 kPa and their programmed cell death were labeled by using TdT-medi-ated-dUTP nick and labeling (TUNEL).
RESULTSDental follicle cells cultured were elongate shape and exhibited fibroblastic characteristics. Compared with 0 kPa, programmed cell death cells on human dental follicle cells were increased 0.23% and 31.65% under 50 kPa and 100 kPa hydrostatic pressures respectively. 100 kPa group increased significantly (P < 0.01).
CONCLUSIONIt suggested that programmed cell death occured in human dental follicle cells cultured in vitro and was influenced by different hydrostatic pressures. Hydrostatic pressure may improve tooth erup-tion through dental follicle.

Ongoing study on the chemical constituents of the roots of Macleaya microcarpa led to the isolation of eight compounds of derivatives of triterpenes and organic acids in addition to some previously identified benzophenanthridines. The eight compounds were identified by spectroscopic methods as well as comparison with literature values as 1-oxo-2, 22 (30)-hopandien-29-oic acid (1), 3-oxo-12-oleanen-30-oic acid (2), 3α-hydroxy-12-oleanen-30-oic acid (3), 3β-hydroxy-12-oleanen-30-oic acid (4), ferulic acid (5), ferulic acid 4-O-β-D-glucoside (6), 3-O-feruloylquinic acid (7), and methyl 3-O-feruloylquinate (8). Of which, 1 is a new triterpenoid of hopanes and 2-8 are isolated from M microcarpa for the first time. In order to discover natural active compounds as potential agents of anti-ulcerative colitis (UC), an in vitro drug high-throughput screening model targeted x-box-binding protein 1 (xbp1) was employed to evaluate the activity of the major chemical constituents of M microcarpa. The result confirmed that two dihydrobenzophenanthridines, dihydrosanguinarine (9) and dihydrochelerythrine (10), showed a certain activity on activating the transcription of xbpl, a transcription factor (TF) associated with the occurrence, development, and potential treatment of UC, with their relative activating ratios being 1.76 and 1.77 times, respectively, as compared with control group.

In July 1997, a strain (GB30) of virus was isolated from 60 samples of brain tissues of Murina aurata (Chiroptera: Vespertilionidae) co llec ted in Gengma county, Yunnan province, China. Isolation of virus was negative fr om 4 samples of brain tissues of Rousettus leschenaulti (Chiroptera: Pteropo did ae) collected in Gengma. GB30 virus strain could regularly cause illness and dea th in suckling mice, produced evident CPE in BHK21 cells. It agglutinated red b lood cells of dove at pH5.75~7.4. This virus has been identified serologically by hemagglutination inhibition and immunofluorescent tests using Japanese enceph alitis (JE), dengue (DEN) type 1,2,3,4, and chikungunya (CHIK) viruses monoclona l antibodies, and JE and sindbis (SIN) viruses immune sera. It showed specific r eaction to JE virus only and no reaction with DEN 1~4, CHIK and SIN viruses. Th erefore it can be identified as JE virus. This is the first report on the isolat ion of JE virus from Murina aurata. The results showed that bats are conside red as the reservoir and amplifier host of JE virus transmission in nature.
