RESUMEN
BACKGROUND: Dermatoglyphic patterns that are often utilized in judicial and legal investigations are valuable in diagnosis of many diseases related to genetic disorders. Caries, being infectious in origin, might be related to genetics as well. Hence, these patterns are of significance in predicting caries development. MATERIALS AND METHODS: DMFT (decayed, missing, filled teeth) score of 300 female subjects within the age group 0f 18-25 years were recorded and accordingly divided into 3 groups of 100 each; group 1 (DMFT score=0), group 2 (DMFT score < 5) and group 3 (DMFT score ⥠5). Dermatoglyphic patterns were recorded using Cummins and Midlo method. pH meter was used for recording salivary pH accurately. Fingerprint patterns and salivary pH recorded were correlated with DMFT scores of subject and control groups. Statistical analysis was performed using ANOVA and Chi-square tests (P < 0.05). RESULTS: The mean salivary pH was least in group 3. The predominant dermatoglyphic pattern observed in groups 1 and 2 was loop pattern whereas, in group 3, whorl pattern was predominant. The TFRC (total finger ridge count) was higher in group 3 compared to the other two groups. CONCLUSION: Caries-free people showed inflated frequency of loops, whereas subjects with high decay score had additional share of whorls. The TFRC was higher in individuals with high DMFT score, and salivary pH was inversely proportional to the DMFT score

Polypeptides of the reference cytopathic strain NADL, and the non- cytopathic strain NY-1 of bovine viral diarrhea [BVD] virus as well as another five non-cytopathic isolates of the same virus were examined by radioimmunoprecipitation of infected bovine fetal spleen by BFS cells. Viral proteins were analyzed by sodium dodecylsulfate- polyacrylamide gel [SDS-PAGE] electrophoresis. Polypeptides of molecular weight of 170 kDa, 130 kDa, 80 kDa, 60 kDa, 539 and 50 kDa were prominent for the NADL strain. The non-cytopathic NY-1 strain showed the same polypeptides profile as the NADL strain except that the polypeptide of 80 kDa was absent. The other five non-cytopathic strains showed the same polypeptides except in two strains where they have an additional two polypeptides of 56 and 54 kDa. But the 50 kDa polypeptide was absent. These results are of diagnostic and epidemiological significance

Se presenta un trabajo de actualización sobre los aspectos técnicos, las generalidades, las aplicaciones, la interpretación y los resultados dela técnica de inmunoperoxidasa. Este procedimiento y sus variantes representan uno de los avances más importantes que se han dado recientemente en la anatomía patológica. Se basa en la detección objetiva por medio de anticuerpos y enzimas marcadoras, de los antígenos característicos de los tejidos normales, de los de diferentes tipos de tejidos enfermos y de los de prácticamente todos los agentes causales de las enfermedades. En otras palabras, se trata de identificar antígenos o marcadores que permitan el diagnóstico preciso de los diferentes tipos de enfermedades. Se presentan también los resultados de los primeros 500 casos estudiados en nuestro laboratorio con la técnica de inmunoperoxidasa
