Anatomical study on the correlation between lip prints and dermatoglyphic pattern on finger tips

Dermatoglyphics and Lip prints have been proved to be ectodermal in origin, completely developed by the end of the fourth month of foetal life and remained unchanged throughout the whole person's life. The correlation between finger and lip print patterns was studied, where it was carried out on six hundred Upper Egyptians [three hundred males and three hundred females,]. Fingerprints were taken by the inked method, whereas, lip prints were taken by two methods; smearing lips with lip-stick and photography by close up camera to focus on lips only. The present work showed that, the complex fingerprint patterns tend to occur in the individuals who have complex up print patterns and the simple fingerprints tend to occur in the individuals who have simple lip print patterns. Furthermore, the complex patterns in one hand are present in the individuals who have complex patterns in the other hand, and the simple patterns in one hand are present in the individuals who have simple patterns in the other hand. In conclusion, the results of the present work may participate in the fields of forensic medicine as a method of personal identification, anthropology and the studies of the genetic diseases

study on the effects of prenatal administration of valproic and [Depakine] on the lumbosacral region of the newly born mice

The present study aimed to demonstrate the embryotoxicity of valproic acid [depakine] [VPA] on the lumbosacral region and to determine the period[s] of susceptibility to produce its hazards. A total number of 40 newly born mice was used. They were divided into a control and three experimental groups. The experimental mothers were injected with 400 mg/kg body weight of sodium valproate three times daily at the 8th, 9th and 10th day of gestation, one day each group. Both control and experimental groups were examined for any external abnormality. The specimens were decalcified, cut at 10 microns thickness and stained by hematoxylin and eosin. Staining of the newly born mice was processed for alizarin red stain. From the results obtained it was concluded that, when VPA must be used during pregnancy, it should be used with strict medical supervision and after closure of the posterior neuropore

study on the postnatal development of the articular cartilage of the knee joint of the albino rat

The postnatal development of the articular cartilage of the femur was studied. A total number of 35 albino rats [Wister strain] was used in this study. The animals were divided into seven groups: Newborn, seven days, ten days, fourteen days, twenty-one days, one month and three months. The study revealed that the immature articular cartilage appeared at the age of twenty-one days in the form of three zones; superficial, intermediate and deep. The mature articular cartilage appeared at the age of three months and consisted of four zones; superficial, intermediate, radial and calcified. The tide mark separated the superficial three zones from the fourth one

Study of the human fetal growth in Upper Egypt

This work aimed to establish standard intra-uterine charts for Upper Egyptian fetuses aged from the 14th gestational week up to 40th gestational week. It included 2460 pregnant women attending the antenatal clinic of the Obstetrics and Gynecology department in the period from October 1992 to July 1994. Using a real time ultrasound apparatus, the following fetal growth parameters were measured; bi- parietal diameter, femur length, abdominal circumference and fetal weight. The study constructed standard growth charts for the previous fetal growth parameters for Upper Egyptian fetuses in the form of growth tables. This work also evaluated the rate of intrauterine growth of the studied parameters that can be of help when abnormal fetal growth is suspected. This work reveled that fetal sex had an ill-defined effect on fetal growth. However, male fetuses tend to be heavier than female fetuses. This difference was found to be insignificant as indicated by T-test. It had also been found that maternal parity had no marked effect on fetal growth parameters in subsequent babies after the first baby. The study found that there was a difference between fetal growth parameters of Upper Egyptians and those of other populations. This difference pointed to the need of the use of such standard growth charts for each locality obtained from its own population

Dermatoglyphic genetic traits and digital patterns in Jubian and Upper Egyptian populations

Finger and palm prints of 200 males and 200 females of Jubian population were examined in an attempt to establish their dermatoglyphic configurations. The results were compared with those of a similar number of Upper Egyptians. Both sexes of both populations had the same formula of total pattern frequency on finger tips [Lu W A Lr]. The right thumb in Upper Egyptian males and right index in both Upper Egyptian sexes showed a higher frequency of whorls than ulnar loops. Radial loops showed a higher frequency of whorls than ulnar loops. Radial loops showed also a higher frequency than arches in the left index and left little fingers in Upper Egyptian males and right ring in Upper Egyptian females. In Jubian females, arches were more frequent than whorls in the left ring finger. The Jubian population showed significantly lower values of the right hand, left hand and in total finger ridge counts in both sexes compared with upper Egyptians. Unlike the Upper Egyptians, the Jubians showed significant bisexual difference in the a-b ridge count and atd angle in both hands

Effects of laser on the bones and cartilages of mice during the early post-weaning period

The knee joint of 15 mice were exposed to daily doses of infra-red laser. Five animals were killed after 10, 20 and 30 days of application with an equal number of age matched controls. Histological examination was carried out on paraffin sections stained with H x and E. The volume and surface densities of the epiphyseal and metaphyseal bone trabeculae of the proximal end of tibia and distal end of femur were calculated using stereological techniques. The thickness of the articular and epiphyseal cartilages were also measured. It was found than laser had an enhancing effect on trabecular bone formation and cartilage thickness. The growth patterns of these structures, however, were preserved. It was concluded that laser application, in therapeutic doses, did not disturb the structural architecture of these structures. These findings need further investigation to explore their possible application
