Radial, ulnar, total absolute finger ridge counts in the upper Egyptians

The radial and ulnar ridge counts were measured from the finger prints of 204 Upper Egyptian individuals [101 males and 103 females]. The individual and absolute individual finger ridge counts were calculated from the above measurements for each finger. They were also totaled for each h and and both h and s combined. The bi-manual and bi-sexual difference were estimated for each parameter. Both sexes showed markedly higher radial count than ulnar one in all fingers. The highest radial count appeared in finger 1 and the lowest in finger 2 in both h and s of both sexes. The lowest count appeared on finger 5 in both h and s in females and left h and only in males. Significant bi- sexual difference was observed in the radial and individual finger count in all fingers except finger 2 while ulnar count failed to show significant bi-sexual difference in any finger. The bi-manual difference showed different pictures in the radial and ulnar counts. The results of the absolute finger ridge counts were compared with those of the individual finger ridge counts. The highest level of correlation appeared between homologous counts on corresponding fingers on both h and s which was even higher than between the radial and ulnar count on the same finger. Next to this, came the correlation between the homologues counts on the adjacent fingers then that between the remote fingers. The least correlation appeared between the radial and ulnar counts on the non-adjacent fingers on opposite h and s. The results of the present study clarify the significance of investigating the radial and ulnar counts separately and provides a baseline for future population studies comparing these important parameters in Upper Egyptians with other populations

Study of the argyrophilic nucleolar organizer regions in different types of gastritis and normal gastric mucosa

Routine paraffin embedded sections from 83 specimens of gastric mucosa were stained using Hx and E, colloidal silver, PAS and Giemsa stains. Different morphological types of AgNOR were counted in different types of gastritis and compared with the normal gastric mucosa. The normal gastric mucosa showed most of the AgNORs as the clusters type while, in general, gastritis cases showed AGNORs mostly as the separate dot type with little of the clusters type. The H-Pylori + ve group of gastritis showed statistically significant higher value of separate and total mean AgNOR counts and a lower value of clusters type count when compared with the corresponding count of the control normal gastric mucosa. The group of H-Pylori - ve gastritis failed to show any statistically significant difference in these counts when compared with the control. It, however, showed statistically significant differences in these counts when compared with the corresponding counts in the H-Pylori + ve group. Within the H-Pylori + ve group the cases showing moderate or sever PNL infiltrate showed the highest mean of the separate type and total AgNOR counts. Cases showing mucous depletion came second in this respect. Other cases of H-Pylori + ve Gastritis with metaplasia and glandular atrophy showed statistically significant difference both types as well as total AgNOR counts when compared with the corresponding count of the normal control gastric mucosa. The only exception was the group of H-Pylori + ve gastritis with normal mucous secretion which failed to show statistically significant difference in the total AgNOR count when compared with the normal control. The observation of highest correlation between AgNOR count and the severity of mucous depletion and PNL infiltration suggested particular influence of these changes on the cellular proliferation rate. We concluded that the difference in AgNOR counts between the normal gastric mucosa and that showing chronic H-Pylori + ve gastritis reflects the increased cell proliferation rate in the last group which provide an evidence for the role of H-Pyloi infection in gastric carcinogenesis. The differential response of the two morphological types of AgNOR in gastritis highlights the importance of examining the morphological types of AgNOR separately and encourages further work on pattern recognition of AgNOR and its relation with different other cellular changes

Anthropometric characteristics of the upper Egyptian newborns in comparison with other countries

A sample of 151 full term infants [89 males and 62 females] was taken from Minia district of Upper Egypt. The infants were subjected to different anthropometric measurements within 24 hours after birth. It appeared that there were no significant differences in the various body measurements between male and female newborns except for skin-fold thickness where female values were significantly greater than male values. Considering that the fat tissue is laid down only during the last weeks of gestation, this represents a marked sex difference. In comparison with some anthropometric measurements of newborn infants elsewhere, the present sample did not show any significantly retarded growth measurement. This indicates that the indicators of growth welfare of the Upper Egyptian newborns are promising and inore attention should be made to the postnatal period
