This study was undertaken to evaluate the dermatoglyphic pattern among deaf and mute children affected with caries and children without caries. A total of 400 school children in the age group of 4-9 years were selected using purpose sampling method. Their fingerprints were recorded using duplicate ink and the frequency of occurrence of type of dermatoglyphic pattern of finger tips was noted. The caries experience was clinically assessed by dmft/DMFT index. Statistical analysis was performed using Mann-Whitney test. Though, the arch pattern was commonly seen in children with caries and control group it was not statistically significant. Finger prints of caries free females and females with caries showed more of arch followed by loops. In caries free males common pattern was arch and in males with caries the pattern seen was arches followed by loops. However, these findings were not statistically significant. Dermatoglyphics can be an appropriate method to explore the possibility of a non-invasive and an early predictor of dental caries. Since, this is an inexact science, further extensive research and studies in the field have to be done in order to determine the significance of dermatoglyphics with dental caries.

Objective:To investigate the component changes in compound granatum berberine capsules after the radioactive ray ir-radiation sterilization. Methods: The chromatographic fingerprints were obtained on a Diamonsil C18 analytical column ( 250 mm × 4. 6 mm,0. 5 μm) with solvent system composed of acetonitrile-0. 033 mol·L-1 potassium dihydrogen phosphate, the flow rate was 1. 0 ml·min-1 and the detection wavelength was set at 265nm, the column temperature was maintained at 30℃, and the injection vol-ume was 10 μl. Results:Totally 10 co-possessing peaks were selected as the fingerprint peaks for compound granatum berberine cap-sules, and the fingerprints exhibited promising separation for each peak and revealed the fingerprint information according to the techni-cal requirements of fingerprints for Chinese traditional medicines. Most components were with different degrees of reduction, and some peaks even lost after the irradiation. Conclusion:The main ingredients show no statistically significant change after irradiation ( P>0. 05), suggesting the sterilization method is suitable for the preparation.

AIM:To develop a new identification and analyfical method for Cornu Cervi Pantotrichum . METHODS: Powder X ray diffraction Fourier fingerprint pattern was adopted. RESULTS: The reference X ray diffraction Fourier fingerprint pattern and characteristic diffraction peaks of Cornu Cervi Pantotrichum were obtained by three samples of Cornu Cervi Pantotrichum and one sample of Cornu Cervi Pantotrichum . CONCLUSION: This method can be used for identification of Cornu Cervi Pantotrichum .
