60 Wistar rats were divided randomly into two groups after a week feeding, 30 rats in study group fed by high dose of NaF water(NaF 200mg/L), others in control group fed by pure water. The serum and urine fluoride were detected at the fourth, eighth and twelfth week. At both the beginning and the twelfth week of the study, all thoracic spine were examed by CT scan. The rats of both groups were sacrisficed at the twelfth week. 5mm long thoracic spinal cord were harvested from the sacrisficed rats. Cytologic changes of neurocytes in thoracic spinal cord after chronic fluorosis were analysed by HE staining apoptosis was marked by a terminal deoxyribo-nucleotide transferase-mediated UTP-biotin nick end labeling and expression of Caspase-3 was determined by immunohistochemistry through 5μm thick slices.

There is evidence of time-related enhancement of the lesion. Post contrast CT scan shows a high density seen mostly in the periphery of the mass and the high density progressly toward the center. Some of the lesions become isodense or hyperdense. Some become smaller, and smaller. The enhanced density lasts a rather long period of time and sometimes up to 30 minutes. It is rather characteristic in disgnosing the cavernous hemangioma of the liver and comparable with the angiographic pattern.

This thesis studies on the implementation of 1024-bit RSA chip on FPGA deeply. The main work are as follows: the basic Montgomery algorithm is analyzed, the advantages and disadvantages of its modified algorithm CIOS and FIPS in hardware implementation are given out; By adopting high-radix architecture and using 32 bit parallel multiplier which presented by Altera LPM library as the core operation module, a kind of modular multiplier architecture design is proposed; Besides it. single modular multiplier is used and the serial binary exponent scan algorithm from left to right is adopted. The RSA modular exponentiation operation with very long integers completes by time-sharing transferring modular multiplier. The final implementation of 1024-bit RSA cryptography chip is based on Altera FPGA EP1
