Correlation between Dermatoglyphics, Dental Caries and Salivary pH: An Invivo Study.

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.

Rat hippocampus and primary immune response.

During immune challenge hippocampal region shows time-dependent changes in neurotransmitter levels. Hence in the present study the effect of electrolytic lesion in the dorsolateral hippocampus (DLH) and ventral hippocampal formation (VHF) (to create a disturbance in neurotransmitter levels) on humoral immunity in albino rats has been studied along with appropriate controls. Haemagglutination titre, IgM and IgG levels were monitored on the 5th day after an immune challenge by sheep red blood cells (SRBC) suspension.

Neuro-immunomodulation by dorsolateral hippocampus--role of macrophages,T and B cells.

In dorsolateral hippocampal lesioned, Sham and control animals, the total number of splenocytes was determined and macrophages, B cells and T cells were isolated and their percentage distribution in total splenocytes were determined. The leukocyte migration inhibition was studied in these groups using different fractions of splenocytes namely whole splenocytes, macrophage removed fraction, and nylon wool eluted T cell population. The same groups were also studied after an antigenic challenge.
