Seven cases of benign bone tumors, a case of spinal fusion and. seven rases of un-united fractures of shafts of long bones, were treated with a.llogenir bone matrix gelatin (BMG) implants and were followed up for more than one year. All tumor cases were cured by osteo-induction from BMG, while only three of the seven fractures united. Two of the failures were reimplanted with BMG and failed again. Not a single case developed post-operative infection nor immunologic reaction. The BMG used was obtained from the same preparation, so that deterioration of its biological activity by endogenous protease was not likely. BMG small BMG cubes were used in tumor cases and slabs in fractures. The small cubes . were mixed with pieces of gel-foam and parked into the post-operative bony cavities while the slabs were arranged layer by layer at the fracture sites. This might be one of the reasons why the tumor rases had higher rate of cure Another reason was that non-unions needed prolonged, continuous and firm internal and external fixation post-operatively while the tumor cases needed not The amount of BMP calculated from BMG was not enough for early and solid osteogenesis. In the authors'opinion, with the use of new biomaterial, it should be followed by new method of application, but the principles of surgery should not be changed

Objective To study improvement of cognitive function impairment of vascular dementia rats induced by a permanent bilateral ligation of common carotid arteries (2VO) after administration of leptin in brain. Methods Hippocampal neurons was isolated and cultured from SD rats. At oxygen-glucose deprivation condition, protection role of leptin on hippocampal neurons was observed and expression of leptin receptor was detected. Animal model of rats was established by 2VO. Pre-treatment VaD model of leptin was established by administration leptin into hippocampus region. The Morris water test was performed to detect difference in the cognitive function between VaD group and control group. Neuron apoptosis in hippocampus tissue were determined with TUNEL. Results Leptin receptor expression could be seen in hippocampal neurons. After oxygen-glucose deprivation cultured for 12 h , plenty of apoptotic cells were seen in hippocampal neurons, apoptosis rat was up to (72.96 ± 6.25) % , while apoptosis rate was (46.33 ±7.85)% and (23.58 ±5.08)% in 1 ( μg and 5μg leptin treatment group,respectively. Compared leptin treatment group with control group,difference had a statistical significance(P<0.01). Compared with untreated VaD group, latency time was shorter and average velocity was increased in leptin-treat-ment VaD group. Neuron apoptosis in hippocampus tissue of leptin-treated group were different significantly from those of untreated group (P < 0.01). Conclusion Leptin could protect hippocampal neurons from apoptosis in vitro. Cognitive function impairment could be improved by administration of leptin into brain in VaD rats.
