The gray vibrissae of Korean males(n =189) between 15 and 75 years old and females(n =111) between-15 and 74 years old who visited the department of otorhinolaryngology, Konkuk university Chungju hospital during 1996 to 1998, were counted for the purpose of estimating approximate age range in individuals of unknown age . The lowest age appearing gray hairs in both sexes was 15-year-old. The Pearson's correlation coefficient in both sexes was 0.490 (p<0.01). The age appearing gray vibrissae in females was slightly earlier than that of males, however, the differences between right and left sides of nasal cavity were insignificant. This method of counting gray vibrissae would be useful to estimate age range in personal identification together with other methods available until now.

PURPOSE: The aims of this study were to investigate the frequencies and role of hepatitis B virus(HBV) precore and core promotor mutations in children with chronic hepatitis B infection. METHODS: Sera from 46 children with chronic hepatitis B infection were analyzed by direct sequencing of polymerase chain reaction product of HBV DNA. In this study, the patients were divided into vertical and non-vertical groups according to the mode of HBV transmission. Statistical analysis was performed by using Fisher's exact test. RESULTS: Forty-six adr type of HBV DNA were analyzed. The mutations in HBV precore region were observed in 12(26.1Yo) of 46 cases. The GA mutation of nucletide(nt) 1896 was observed in 5 cases(10.9Yo). The frequency of mutations in HBV precore region of the non-vertical group (6/16; 37.5Fo) was higher than that of the vertical group(6/30; 20M), but there was no statistical significance. The mutation in HBV core promotor region was observed in 40(87.0%) of 46 cases. The A-->T mutation of nt 1762 or G-->A mutation of nt 1764 were observed in 24(52.2%) of 46 cases, and 23 cases revealed combined mutation at both positions 1762 and 1764. The frequency of mutations in HBV core promotor region of the vertical group(28/30; 93.3Yo) was higher than that of the non-vertical group(12/16; 75.0M), but there was no statistical significance. The frequencies of mutations in HBV precore and core promotor regions of the HBeAg negative patients was higher than that of HBeAg positive patients, but there was no statistical significance. Also there were no significant correlations between the frequencies of mutations in HBV precore and core promotor regions and AST, ALT level or the level of HBV DNA. CONCLUSION: These observations suggest that mutations in HBV precore and core promotor regions were frequently detected in children with chronic hepatitis B infection. There were no statistical significant differences in the frequencies of mutations in HBV precore and core promotor regions between vertical and non-vertical transmission groups.

Due to the instability of intertrochanteric fractures in elderly patients, various methods of reduction and fixation were introduced to obtain stable reduction and solid union, But there have been many controversies regarding advantages between anatomical reduction group and non-anatomical reduction group. The authors analyzed the 68 unstable intertrochanteric fractures out of total 94 cases of intertrochanteric fractures treated from Jan. 1988 to Jan. 1994 with mean follow-up 17 months and evaluated the radiologic and clinical results between those two groups. The results were obtained as follows: 1. The most common cause was low energy injury and according to the Tronzo classification, the type III was most common in 54 cases (79.4%). 2. The average union time was 14.0wks (84%), the union rate was low in the medialized reduction group(A-P) and anterior displaced reduction group(A-P), anterior displaced and anatomical reduction groups(Lateral). 3. The compression length more than 10mm of lag screw was deep in medialized reduction group(A-P), another displaced and anatomical reduction groups(Lateral). 4. The average length of lag screw sliding was 9.2mm and depth sliding of 6.8mm (74%) was occurred within immediate postoperative 1 month.
