For the purpose of effective therapy and prevention of post weaning E. coli diarrhea, Enrofloxacin-(Baytril premix) was administered in the feed and a series of investigations were made the occurence of diarrhea, weight gain, feed conversion rate, changes In the counts of faecal E. coli and susceptibility of the isolated E. coli strains to antimicrobials. The results obtained were as follows 1. The weaned piglets which were treated with Baytril premix gained the average body weight of 3.2kg over the control group at the age of 62 days. The result indicates a marked weight gain effect which, by statiscal analysis, showed a significant difference(P<0.01). Administration of Baytril premix also resulted in the improvement of feed conversion rate and provention of post weaning diarrhea. 2. The counts of faecal E. coli in Baytri premx treated piglets showed a marked decrease from 3.14${\times}$10$\^$8/cells/g to 2${\times}$10$\^$7/cells/g at 5days post treatment and 1${\times}$10$\^$5/cells/g at 10 days post treatment. 3. 10 strains of E. coli isolated fred the experimental pig farm were highly susceptible to Bayoil, gentamicin and trimethoprim plus sulfamethoxazole.

In the present study, the effects of extracts from Korean plants on the DNA damage response in HaCaT cells exposed to ultraviolet B (UVB) were investigated. The activity of cells treated for 24 hr with ethanol extracts from Vaccinium spp. (VS), and Vitis vinifera L (VV) alone was similar to that of the non-treated control, but gradually decreased at concentrations above $200{\mu}g/mL$. However, when post-incubation of UVB-exposed cells was carried out for 24 hr in medium containing VS or VV extracts, the cell activity increased in a concentration-dependent manner compared with that in the normal growth medium. The cell viability of UVB-exposed cells also increased when post-incubated in medium containing VS or VV extracts, in a concentration-dependent manner. Nuclear fragmentation analysis showed that post-incubation with VS or VV extracts decreased the UVB-induced apoptosis by about 10 and 13%, respectively, of that in cells post-incubated in growth medium. After 24 hr of post-incubation in medium containing VS or VV extracts, the level of CPD and 8-OHdG decreased in time- and concentration-dependent manners. Overall these results suggest that VS and VV extracts assist the survival of UVB-exposed cells, in accordance with the respective decrease in the levels of UVB-induced DNA damage.

Purpose: Kimura's disease is a relatively rare head and neck tumor that frequently occurs in young orientals accompanied with eosinophila. We shared our experience of two cases of Kimura's disease, treated by radical resection and post operative steroid therapy, so we report the correlation of eosinophil counts and disease progression. Methods: A 25 years old male came to the clinic with a mass localized to the right cheek inferior to the right auricle. We could not resect the mass totally. During the follow up period, we checked the eosinophil counts, and steroid therapy was started 7 months after the surgery. A 34 year old female came to the clinic with a mass localized inferior to the left auricle reaching from the posterior portion of the auricle to the left temporal portion. We tried to remove as much tumor as possible, save the temporal region, in regard to the impairment of blood supply to the auricle. After operation, steroid therapy was started. Results: In the first case, the tumor was easily approachable, and radical resection of the tumor with post operative steroid therapy was an effective treatment. In tumors located at difficult regions to remove, as in the second case, optimal debulking and post operative steroid therapy was also effective in treating Kimura's. There were no recurrences in both cases. Eosinophil counts were always reduced after surgery and steroid therapy, and during the period with low eosinophil counts, there was no recurrence of Kimura's disease. Conclusion: Surgery and post operative steroid therapy were effective in treatment of Kimura's disease, and we could assume eosinophil counts as a good indicator for evaluation of the prognosis of Kimura's disease during the follow up period.

Objectives: Hydrogen peroxide ($H_2O_2$) surface treatment of fiber posts has been reported to increase bond strength of fiber posts to resin cements. However, residual oxygen radicals might jeopardize the bonding procedure. This study examined the effect of three antioxidant agents on the bond strength of fiber posts to conventional and self-adhesive resin cements. Materials and Methods: Post spaces were prepared in forty human maxillary second premolars. Posts were divided into five groups of 8 each: G1 (control), no pre-treatment; G2, 10% $H_2O_2$ pre-treatment; G3, G4 and G5. After $H_2O_2$ application, Hesperidin (HES), Sodium Ascorbate (SA) or Rosmarinic acid (RA) was applied on each group respectively. In each group four posts were cemented with Duo-Link conventional resin cement and the others with self-adhesive BisCem cement. Push-out test was performed and data were analyzed using 2-way ANOVA and tukey's post-hoc test (${\alpha}=0.05$). Results: There was a statistically significant interaction between the cement type and post surface treatment on push-out bond strength of fiber posts (p < 0.001, F = 16). Also it was shown that different posts' surface treatments significantly affect the push-out bond strength of fiber posts (p = 0.001). $H_2O_2$ treated posts (G2) and control posts (G1) cemented with Duo-link showed the highest ($15.96{\pm}5.07MPa$) and lowest bond strengths ($6.79{\pm}3.94$) respectively. Conclusions: It was concluded that $H_2O_2$ surface treatment might enhance the bond strength of fiber posts cemented with conventional resin cements. The effect of antioxidants as post's surface treatment agents depends on the characteristics of resin cements used for bonding procedure.

Mophological normal of unfertilized oocytes, which was collected 12-14 hours after human Chorionic Gonadotropin(jCG) injection, was not influenced by chronically adiministration of cocaine for 2 weeks in mice. Proportion of normal unfertilized oocytes in non-cocaine treated group (control), `0 mg/kg and 20 mg/kg cocaine treated group based on body weight with subcutaneous(s.c.) daily injection of cocaine for 2 weeks were 92.9%, 85.6% and 90.9%, respectively. There is no significant difference between control and cocaine treated groups. Two to 8 cell stage embryos collected 24-48 hours post hCG in control group were 66.7%, whereas, 10 mg/kg and 20 mg/kg groups treated with cocaine was 12.5% and 27.3% respectively. Although control and treated groups are significantly different (p<0.05) the developmental score of 2 to 8 cell stage embryos collected at 24-48 hours post HCG, there is no difference between 10 mg/kg and 20 mg/kg treated with cocaine groups. These results indicated that the normal embryos of the roups of cocaine administration were significantly amested when compared with that of control group. The proportion of 2 to 8 cell stage embryo reaching the blastocyst stage, which were cultured 48-52 hours with 5% $Co_2$ in air at $37^{\circ}C$, were 93.9% in control group and, 70.4% and 71.9% in each 10 mg/kg and to blastocyst in vitro culture was significantly limited embryos obtained from cocanized mice compared with those of control mice. These results suggest that episode of cocaine intoxication can cause impaiment of early embrygenesis in the mouse.

Objective: Two ex vivo experiments were conducted to verify the effect of barley grain (Nusrat cultivar) treated with alkaline compounds (AC) including alum, ammonium, and sodium hydroxide or cation-exchanged organic extracts (OE) prepared from alfalfa hay, sugar beet pulp and Ulva Fasciata, on extent and digestion of starch. Methods: In the first study, the in vitro first order disappearance kinetic parameters of dry matter (DM), crude protein (CP) and starch were estimated using a non-linear model ($D_{(t)}=D_{(i)}{\cdot}e^{(-k_d{\cdot}time)}+I$, where: $D_{(t)}$ = potentially digestible residues at any time, $D_{(i)}$ = potentially digestible fraction at any time, $k_d$ = fractional rate constant of digestion (/h), I = indigestible fraction at any time). In the second experiment, the ruminal and post-ruminal disappearance of DM, CP, and starch were determined using in situ mobile nylon bag. Results: Barley grains treated with alum and alfalfa extract had a higher constant rate of starch digestion (0.11 and 0.09/h) than others. Barley grain treated with OE had a higher constant rate of CP digestion and that of treated with AC had a higher constant rate of starch digestion (0.08 and 0.11/h) compared with those of the other treatments. The indigestible fraction of starch treated with alum and sugar beet pulp extract was higher than that of the control group (0.24 and 0.25 vs 0.21). Barley grain treated with AC and OE had significant CP disappearance in the rumen, post-rumen and total tract, and also starch disappearance for post-rumen and total tract compared with the untreated (p<0.001). Conclusion: This study demonstrated that AC and OE might have positive effects on the starch degradation of the barley grain. In addition, treating barley grain with alum and sugar beet pulp extract could change the site and extend digestion of protein and starch.

The effect of bonding misfit on single crystallization of transient liquid phase (TLP) bonded joints of single crystal superalloy CMSX-2 was investigated using MBF-80 insert metal. The bonding misfit was defined by (100) twist angle (rotating angle) at bonded interface. TLP bonding of specimens was carried out at 1523K for 1.8ks in vacuum. The post-bond heat treatment consisted of the solution and sequential two step aging treatment was conducted in the Ar atmosphere. The crystallographic orientation analysis across the TLP bonded joints was conducted three dimensionally using the electron back scattering pattern (EBSP) method. EBSP analyses f3r the bonded and post bonded heat treated specimens were conducted. All bonded joints had misorientation centering around the bonded interface for as-bonded and post-bond heat treated specimens with rotating angle. The average misorientation angle between both solid phases in bonded interlayer was almost identical to the rotating angle at bonded interface. HRTEM observation revealed that the atom arrangement of both solid phases in bonded interlayer was quite different across the bonded interface. It followed that grain boundary was formed in bonded interface. It was confirmed that epitaxial growth of the solid phase occurred from the base metal substrates during TLP bonding and single crystallization could not be achieved in joints with rotating angle.
