  • Hepatoprotective activities of 26 traditional Korean herbal prescriptions described in Donghibogam were evaluated in vivo and in vitro screening system. Twenty one prescriptions appeared to be active. Six prescriptions among them showed highly significant hepatoprotective activities; Shihogyegy-Tang(柴胡桂枝湯), Soshiho-Tang(小柴胡湯), Shiho plus Younggolmoryo-Tang(柴胡加龍骨牡蠣湯), Yinjinho-Tang(茵蔯蒿湯), Yinsam-Tang(人蔘湯) and Shashim-Tang(瀉心湯). Shihogyegy-Tang was most active. They reduced the release of transaminases from dissociated hepatocytes by thioacetamide, and serum transaminases and alkaline phosphatase activities of rat with carbontetrachloride-induced hepatitis. They inhibited significantly lipid peroxidation and cellular fatty change of liver by carbontetrachloride.

  • The hydrogel process is a different form of ultrafiltration and has been used to separate biological molecules. In this study, the gel pore size was predicted by pulse NMR technique and neural network using a database obtained from gel filtration chromatography and diffusion experiment. Recombinant alkaline phosphatase expressed in insect cells was concentratred 1.5 times by hydrogel ultrafiltration by swelling at 2$0^{\circ}C$ and collapsing at 35$^{\circ}C$ at 53-65% separation efficiency and 78-83% enzyme recovery. Wild and recombinant Autographa californica unclear polyhedrosis viruses (AcNPV) were also concentrated 1.4 and 1.6 times of the feed solution at 48.5 and 60.0% separation efficiency, respectively Hydrogel ultrafiltration appears to be an attractive alternative for the concentration of AcNPV and recombinant proteins from insect cells.

  • We investigated the effect of safflower-seed on fracture healing of fracture model in rat. Fracture healing was evaluated by examining the degree of wound healing macroscopically, radiography, bone histomorphometry and biochemical examination. After 1, 3, 5, 7 days, the would healing was accelerate in safflower-seed diet group. Radiography does not reveal the difference in fracture healing between two group. After 2 weeks, safflower-seed had a significant, stimulatory effect on external callus formation (p<0.05). But after 4, 6, 8 weeks, no difference was observed between normal and safflower-seed dietgroup in callus size. Urinary hydroxyproline, osteocalcin and total alkaline phosphatase decreased significantly (p<0.05) in safflower-seed treated group at 2 week after tracture.

  • Colostrum basic proteins (CBP) (MW 1$\sim$30 kDa) were isolated from bovine colostrum using a series of ultrafiltration processes and their effects on osteoblast cell proliferation and bone metabolism were investigated in cell line and animal models. Treatments with CBP (1, 10, 100 $\mu$g/mL) dose-dependently increased cell proliferation of osteoblastic MC3T3 cells. Alkaline phosphatase activity, a marker of osteoblastic phenotype, in the cells was also increased after treatments with CBP in a dose-dependent manner. Significant increases in bone density were observed in femur of ovariectomized rats which were fed a diet with 1% and 10% CBP, compared to rats fed a normal diet. These results suggest that CBP may increase bone mass and density and be useful for the prevention of bone-related diseases.

  • One of the biggest problems involved in transgenic animal production is lack of appropriate market genes. To overcome this problem, we tested whether the genes of SEAP (secreted alkaline phosphatase) and GFP (green fluorescence protein) on our retrovirus vectors can be applicable to the transgenic animal production. The main advantage of these marker genes over other generally mainpulation can be selected without sacrificing viability. The results obtained in this study are summarized as follows: 1. Removal of zona pellucida from the mouse zygotes did not affect embryo developments to blastocysts. 2. Co-culture of zona-free embryos with virus-producing cells for 6 hours also did not affect embryo developments to blastocysts. 3. Among 58 blastocysts developed from the zona-free zygotes co-cultured with the virus-producing cells, SEAP expression was observed from the 6 blastocysts. 4. Expression of the GFP gene was detected from the virus- producing cells but no embryo expressing the gene was counted among 50 blastocysts developed from the zona-free zygotes co-cultured with the virus-producing cells.

  • Objectives : This study was undertaken to study the action mechanism of Rhizoma Davalliae (RD) at parameter related to regulating bone density. Methods : We measured alkaline phosphatase activity and the contents : calcium, hydroxyproline, osteocalcin, calcitonin, and parathyroid hormone after the ovariectomized rats had been treated with RD for 30 days. Results : The following changes occurred: First, the serum calcium content and the calcitonin content, which decreased in ovariectomized rats, increased with RD treatment. Second, the serum alkaline phosphatase activity, the parathyroid hormone ativity, the osteocalcin content, the urinary calcium content, and the hydroxyprolin content-which increased in ovariectomized rats-decreased with RD treatment. Conclusions : These results show that RD treatment can recover abnormal calcium metabolic process by sex hormone inequality, promoting bone formation and inhibiting bone absorption.

  • This study was performed to investigate therapeutic effects of Achyranthis Radix extract and chitosan on the growth and differentiation of rat calvarial cells. it was found that treatment of methanol extract of Achyranthis Radix for 2 days caused 2.4-fold increase in the growth of rat calvarial cells. However, chitosan treatment caused only 1.9-fold increase in the cell growth. Treatment of methanol extract of Achyranthis Radix for 14 days caused 2-fold increase in the growth of rat calvarial cells. Alkaline phosphatase activity, one of the markers for bone cell differentiation, was increased approximately by 1.7-fold and 2.9-fold by the treatment of methanol extract of Achyranthis Radix for 2 days and 14 days, respectively. These results suggest that Achyranthis Radix extract could be beneficial for bone regeneration.

  • The purpose of this study was to probe the influences of NaF oral administration on a dose-effect relationship between fluoride levels of serum enzyme activity such as alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) in rats fed experimental diets for 5 weeks. All groups increased the activity of serum ALP, AST, ALT, and LDH levels with increasing NaF. In addition the fluoride levels of serum and organ tissues (liver, brain, heart, lung, kidney) in oral NaF groups (NF3~NF50) were significantly increased by adding sodium fluoride in comparison with normal diet group (ND) (p<0.05). These results, a high concentration of sodium fluoride was determined that the toxicity to various organ tissues.

  • We isolated two Cd-binding high molecular weight proteins from intraperitoneally cadmium injected rat liver. Molecular weight of Cd-BP(I) purified from Sephacryl S-100 and DEAE Sepharose column chromatography and Cd-BP(II) purified from DEAE Sepharose column chromatography and Sulphonyl Sepharose column chromatography was 33,000 and 18,400, respectively. Alcohol dehydrogenase and alkaline phosphatase acitivities were not detected from two purified proteins.

  • Pyrethroids are one of the most commonly used insecticides in worldwide. but it remains unclear whether pyrethroid compounds possess endocrine disrupting activity or not. T47D cells, an estrogen receptor positive human breast cancer cell line. is known to induce alkaline phosphatase (AlkP) only in response to progestins. Because the action of estrogen may be changed by the action of progestins (Kraus et al. 1995), it is important to examine the potential to produce progestin-mediated effects for determining endocrine disrupting activity of chemicals(LiLorenzo et al. 1991).
