  • The attachment and adhesion of RAW 264.7 and MC3T3-E1 cells to titanium (Ti) discs with various degrees of roughness was investigated. The attachment, adhesion, and proliferation of these cells were evaluated after 4 hr, 24 hr and 7 day incubations. Both RAW 264.7 and MC3T3-E1 cells showed a time-dependant correlation between attachment and adhesion on the surface of the titanium discs. Both types of cells tended to have higher survival rate on these discs as the surface roughness increased. The percentage of adherent inflammatory RAW 264.7 cells was greater than MC3T3-E1 cells at 24 hr, but this was reversed at 7 days in culture. The morphology of osteoblastic MC3T3-E1 cells at 24 hr, determined using a surface emission microscope (SEM), appeared flattened and spread out while inflammatory RAW 264.7 cells were predominantly spherical in shape. The adhesion of both cell types on the titanium discs was dependant on the levels of fibronectin adsorbed on the disc surface, indicating that serum constituents modulate the efficient adhesion of these cells. Our data indicate that the cellular response to the titanium surface is dependent on the types of cells, surface roughness and serum constituents.

  • This experiment was done to investigate the effects of Ojajiwhangeumja(OJWEJ) to the symptoms of senility. To prove the effects of OJWEJ we injected scopolamine(1mg/kg) to the vein of rats. And we measured the blood cells(WBC, RBC, Platelet), constituents of serum(BUN, creatinin, glucose, uric acid), endurance of films of the red blood cell to erythrocyte hemolises, the activity of cholinesterase in serum, TBA and the activity of catalase, SOD in the purified microsome of brain tissue of rats. The results were as follows; 1. The number of white blood cells, platelet was increased significantly in the group treated by OJWEJ in comparison with control group. 2. The number of BUN, creatinin, glucose of serum decreased significantly in the OJWEJ treated group compared with control group. 3. The erythrocyte hemolises in red blood cells restrained significantly in the group treated by OJWEJ in comparison with control group. 4. The activity of cholinesterase in OJWEJ treated group increased significantly compared with control group. 5. The amounts of malondialdehyde of serum decreased significantly in the OJWEJ treated group in comparison with control group. 6. The catalase in the microsome of rat brain was activated significantly in the group treated by OJWEJ compared with control group. 7. The superoxide dismutase in the group treated by OJWEJ activated significantly in comparison with control group. According to this experiment it is suggested that OJWEJ accelerates the activity of colinesterase and restrains the creation of erythrocyte hemolises and accumulation of senile substance. But I look forward to see the further research to be made.

  • In this study, essential oils were extracted from the leaf of Chamaecyparis obtusa (CLEO), indigenous to Korea, CLEO constituents were analysed, and the effects of CLEO on airway hyperresponsiveness (AHR) and airway inflammation (AI) were investigated in Ovalbumin (OVA)-induced asthma mouse model. Terpenoid components among identified CLEO constituents made up more than 80%. The CLEO-treated group in comparison to the control group showed reduced AHR, the decrease of eosinophil number in the bronchoalveolar lavage fluid (BALF), reduced specific anti-OVA IgE level in the serum, and a significant reduction in Th2 cytokines levels in the BALF with concentration. We concluded that CLEO have an alleviating effect on asthma-like symptoms such as AHR and AI. Further studies about antiasthmatic effect are necessary on the focus of single component of CLEO.

  • Herbal medicines have been used since the dawn of civilization to maintain health and to treat diseases. Diabetes mellitus is one of the leading cause of death in many developed countries. The incidence of diabetes is increasing at an alarming rate in India. It was estimated that India which had 19.4 million diabetes in 1995 is expected to register a near threefold increase by. Many plants reported to be useful for the treatment of diabetes mellitus in ayurvedic medicine, are being tested for their hypoglycemic activity in experimental animals Lagerstroemia flos- reginae is one such plant commonly found as shade trees in Kerala. In Ayurveda both root and leaves are used in the treatment of diabetes. The main objective of this study was to assess the antidiabetic effect of the alcohol extracted leaves of Lagerstroemia flos- reginae in alloxan induced diabetic rats in terms of controlling blood glucose level, lipid profile, bilirubin, uric acid in serum and lipid peroxides and glutathione in the liver of the experimental animals. The present study has been undertaken to observe the protective effect of the active constituents of Lagerstroemia flos- reginae leaf extracts against alloxan induced diabetes in experimental animal model. The activity of the active constituents was compared with Daonil -a standard drug.

  • In order to evaluate the hepatoprotective effect of an herb distillate, ie., a mixture of 28 traditional Korean herbs, germanium, tormarine and Gijangsoo (Gijang water), $CCl_4$ was intraperitoneally administered to rats before or after supplementation of the diluted herb distillate (HD) for 2 weeks. Then hepatic xanthine oxidase activity and serum lipid profiles were determined. The experimental groups had higher feed intake than the normal control (NC), but had lower weight gain. Water intake and the amount of feces were not significantly different, but urine was excreted in lower amounts in all the experimental groups compared to the NC. Liver weights in the HD-supplemented groups were lower than that of the distilled water-supplemented groups (DW-groups) after $CCl_4$-administration. Serum ALT activities in all the experimental groups were higher than that of the NC-group. However, the increasing activity of serum ALT in the HD-supplemented groups (HD-groups) was lower than that of the DW-groups. Total serum and LDL-cholesterol levels were higher in all the $CCl_4$-administered groups than in the NC-groups, and serum HDL-cholesterol levels were lower in all the experimental groups compared with the NC-groups. Meanwhile, the increasing rate of total serum and LDL-cholesterol levels and the decreasing rate of HDL-cholesterol in the HD-groups were lower than that of the DW-groups. But, levels of serum TG were similar among all the experimental groups. The activities of hepatic xanthine oxidase (XOD) type O of the $CCl_4$-administered rats showed a significant increase in and an increasing rate of XOD in the HD-groups, which was lower than that of the DW-groups. On the other hand, GST activities in all the experimental groups were significantly decreased, and the decreasing rate was lower in the HD-groups than in the DW-groups. The hepatic contents of GSH and LPO in all the rats were not changed by $CCl_4$ administration. These results suggest that the decreased liver damage in the HD-supplemented groups was due to the inhibition of XOD-type O activity by constituents of HD, as well as by a prevention/inhibition of serum lipid profile changes in $CCl_4$-treated rats. However, further detailed studies are needed to support this hypothesis.

  • The composition of dissolved gases and nutrients in a liquid medium were determined for establishment of the optimum conditions for in vitro culture of Helicobacter pylori. A microaerobic condition facored by the organism was prepared by adjusting the partial pressure of the gas, agitation speed, and viscosity of the medium. The gaseous concentrations were controlled by utilizing CampyPak Plus that reduced oxygen while augmenting carbon dioxide. Agitation of the broth facilitated the oxygen transfer to the cells, yet inhibited the growth at high rates. An increase of viscosity in the medium repressed the culture although this variable was relatively insignificant. The chemical constituents of the liquid broth were examined to establish an economic model for H. pylori cultivation. The microbe required a neutral pH for optimum growth, and yet was also able to proliferate in an acidic condition, presumably by releasing the acidity-modulating enzyme, urease. Cyclodextrin and casamino acid were investigated as growth enhancers in place of serum, while yeast extract unexpectedly inhibited the cells. A low concentration of glucose, the unique carbon source for the organism, increased the cell density, yet high concentrations resulted in an adverse effect. Under optimally dissolved gas conditions, the cell concentration in brucella broth supplemented with serum substitutes and glucose reached $1.6{\times}10^8$ viable cells/ml which was approximately 50% higher than that obtained in the liquid medium added with only cyclodextrin or serum.

  • A total of 109 heads of horses and ponies from eight horseback riding clubs nearby Central Taiwan were investigated to evaluate the blood parameters and the biochemical compositions of serum for the documentation of clinical pathological diagnosis and exercise physiology. Blood samples were collected from the jugular vein of resting horses. The sex difference in the blood traits were compared both in horses and in ponies. Results shows that total plasma proteins (PP) and hematocrit (PCV) were found higher in male horses than in females (p < 0.05). The sexual effect also exertes a significant influence on the leucocyte (WBC) count, but not on the erythrocyte (RBC) concentration. According to the differential counts of leucocytes, the number of monocytes and lymphocytes was higher in the male pony than that of in male horse. A close relationship Between the erythrocyte sedimention rate (ESR) and the other blood parameters were found especially in PCV, RBC concentration, and plasma protein level. The average ESR observed at 60 minutes were $21.80{\pm}21.87mm$, $39.50{\pm}18.90mm$ and $43.73{\pm}17.89mm$ in stallions, geldings, and mares, respectively. Most of the biochemical components of horse serum detected were distributed in normal ranges, although some of the items show a great variation in such a large sample size.

  • Comparative blood analysis was carried out to investigate the change of blood constituent in TAE-EUM-IN group and control group. RBC, WBC, hemoglobin, hematocrit, total protein, triglyceride, phospholipid, total cholesterol, LDL-cholesterol, HDL-cholesterol, BUN, creatinine, ACTH, cortisol and prostaglandin E and $F_2{\alpha}$ were measured. And the following results were obtained: 1. In the change of blood cell, the value of hematocrit showed significant difference, while that of RBC, WBC and himoglobin didn't. 2. In the change of protein, the value of total protein showed significant difference, but that of albumin didn't. 3. In the change of lipid and cholesterol in serum, the value of triglyceride, phospholipid, total cholesterol and LDL-cholesterol indicated significant difference, while that of HDL-cholesterol indicated significant difference, while that of HDL-cholesterol didn't. 4. The value of BUN in serum represented significant difference, but that of creatinine didn't. 5. The value of cortisol in plasma showed significant difference, but that of ACTH didn't. 6. The value of prostaglandin E and $F_2{\alpha}$ in plasma showed significant difference. These results suggest that investigation on hormones and blood constituents enables objectification in differentiation of four types of physical constitution.

  • Mold growth decreased nutritive value of wheat straw (WS). Mold increased DM (94 vs 98%) and ADF (51 vs 56%) contents and had no effect on natural detergent fiber (NDF). Crude protein and N values were decreased in moldy wheat straw, Mold increased insoluble N content of wheat straw (WS) from 21 to 27%. Ammoniation increased the CP of nonmoldy straw from 3.8 to 8.3% and moldy straw from (3.3 to 6.2%). Aspergillus and zygomycetes fungal species were most prevalent and total numbers were higher on moldy straw. Ammoniation decreased total numbers of fungal spores on nonmoldy and moldy WS. Ammoniation of moldy WS increased (p < 0.10) feed in take (1.8%) as compared with nonmoldy, ammoniated, nonmoldy and moldy WS. Steers fed moldy WS had lowest (p < 0.10) feed intake (1.3% of BW daily) compared with other diet. There was little difference (p < 0.10) in intake of nonammoniated vs. ammoniated WS. Steers fed moldy straw lost 6 kg BW. Ammoniated, nonmoldy straw elevated Blood Urea Nitrogen (BUN) (10.5 mg/dl). Alkaline Phosphatase (ALK) was greater in steers fed moldy VS nonmoldy straw (148 VS 95 U/liter. p < 0.10).
