The propose of this study was to evaluate the difference of cellular activity dependent on intermittent compressive force by determining the alkaline phosphatase activity. Alkaline phosphatase activity was measured on control and experimental groups every 24, 48, 72hours. Experimental groups consisted of continous and intermittent compressive group which were compressed by 300g/cm2 of diaphram pump. The intermittent compressive group was connected by timer which was worked on 10 minutes an off 10 minutes. The results were as follows; 1. The alkaline phosphatase activity between control and experimental groups showed not significant difference at compressed 24 hours. 2. The alkaline phosphatase activity of experimental groups were more increased than control group at compressed 48 hours. 3. The alkaline phosphatase activity of intermittent compressive group showed significant increased to control group. Whereby continuous compressive group showed not significant difference to control at 72 hours. 4. The alkaline phosphatase activity of intermittent compressive group were stringly increased than continuous compressive groups. 5. Between experimental groups and control group no other morphologic changes were detected by microscopic findings.

The propose of this study was to evaluate the effect of cellular activity of PDL cells dependent on intermittent and continuous compressive force by determining the alkaline phosphatase activity. An intermittent and continuous compressive forces were applied on PDL cells at the confluent stage. The alkaline phosphatase activity was measured on control and experimental groups every 24, 48, 72hours. The experimental group were consist of continous and intermittent compressive group which were compressed by 300g/cm2 of diaphragm pump. The intermittent compressive group was connected by timer which was worked on 10 minutes and off 10minutes. The results were as follow; 1. The alkaline phosphatase activity of intermittent compressive group was lower than control group at 24 hours(P<0.05). 2. The alkaline phosphatase activity between each groups showed no significant difference at 48hours. 3. The alkaline phosphatase activity of continuous compressive group was significantly higher than control group at 72 hours(P<0.01).

80 adult rats were divided into 2 groups of 60 rats before and 20 after kidney transplantion. Study showed that the changes of alkaline phosphatase in kidney before transplation trended to vary paralelly with warm ischemic time (WIT) and cold ischemic time (CIT) and the 5 times higher rate of perfusion than normal did not make the enzyme changed. Post transplantion kidney tissue alkaline phosphatase level varied in correlation with the active capacity of transplanted kidney. Blood creatinine level of the rats within a week after the transplantation has a negative variation with enzyme level

coxon test. All the values of experimental groups are significantly lower than those of control, and the vaules among the experimental groups significantly differ from each other. Alkaline phosphatase level was identical order with the viable cell rate. SEM examination revealed that the PDL fibroblasts adherent on culture dish (control) and group A were spindle-shaped, but on group B and C, the cells were round-shaped without processes.

Methods, data, and discussions of experiments concerning agglutination of human leukemic leukocytes with guinea pig serum and the alkaline phosphatase staining technique by the Azo-dye method are given. An important fact evident from studies of alkaline phosphatase is that there can be chemical differences between cells whose morphology is identical. Even though the results obtained here in the small group of leukemic cases studied by the guinea pig serum agglutination method are not very reproducible, the idea that an antigen-antibody reaction for the determination of leukemia exists, very appealing.

This study was designed to examine the effect of polyP on the periodontal ligament fibroblasts. The cells were incubated for 24 and 48 hours with various concentrations (0.001%, 0.002%, 0.005%, 0.010%, 0.020%, 0.040%) of polyP. Cell activity, alkaline phosphatase activity, and protein synthesis activity of the cells were examined. The results were as follows: 1. Twenty four hours after incubation with polyP, the cell activity of the periodontal ligament fibroblasts was increased. Forty eight hours after polyP application, the activity of the cells was similar to that of control group. 2. Twenty four or forty eight hours after incubation with polyP, the alkaline phosphatase activity of the periodontal ligament fibroblasts was increased. 3. The protein synthesis of the periodontal ligament fibroblasts was not changed after polyP application. These results suggest that, polyP may increase the cell activity and alkaline phosphatase activity of periodotal ligament fibroblasts and polyP may not affect the protein synthesis of the cells.

The quality of life for women after menopause is one of the key health issues today, and osteoporosis is a silently progressing metabolic bone disease widely prevalent in post-menopausal women in India. Rapid bone loss occurs in post-menopausal women due to hormonal factors that lead to an increased risk of fractures. Thus, the present study was undertaken to observe the serum calcium and alkaline phosphatase (ALP) levels in post-menopausal women as these substances are biochemical markers of bone metabolism. In this small-scale cross-sectional study, 100 samples were taken. Of these, 50 were taken from post-menopausal women (experimental group) and 50 were taken from pre-menopausal women (control group). Serum calcium and serum ALP were measured in the blood samples of both groups. The findings demonstrated that the serum calcium level was significantly lower in the post-menopausal group than in the pre-menopausal group, while the ALP level was slightly higher. Therefore, an increase in bone turnover accelerates bone mass reduction in post-menopausal women, whereas a decrease in bone turnover is associated with the preservation of bone mass.
