The purpose of present study was to evaluate the bioequivalence of two enalapril maleate tablets, Renitec^(™) (MSD Korea Ltd.) and Enalace ^(™) (Welfide Korea Ltd.), according to the guidelines of Korea Food Drug Administration (KFDA). Twenty-four normal male volunteers, 22.33±2.55 year in age and 66.54±8.30 ㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After two tablets containint 10 ㎎ of enal-april maleate per tablet wre orally administered, blood was taken at predetermined time intervals and concentrations of enalapril in plasma were determined using LC-MS-MS. Pharmacokinetic parameters such as AUC_(t), C_(max) and T_(max) were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed AUC_(t) and C_(max) untransformed T_(max). There were no sequence effects between two formulations in these parameters. The 90% confidence intervals for the log transfored data were acceptance range of log0.8 to log1.25(e.g., log1.02∼log1.14 and log1.03∼log1.19 for AUC_(t) and C_(max), respectively). The major parameters, AUC_(t) and C_(max), met the criteria of KDFA for bioequivalence indicating that Enalace^(™) tablet is bioequivalent to Renitec^(™) tablet.

A simple rapidly converging iterative method of computing gradually varied steady flow profiles in open channels of any shape, prismatic or nonprismatic, is presented. The method is also applicable to spatially varied steady flow. It is not necessary to determine the shape of the expected profile or the type of flow in advance to proceed with the solution. Computations can proceed either upstream or downstream, regardless of the type of flow, once the channel, discharge, and the initial depth of flow are specified. The procedure for hand computation is illustrated by an example and a FORTRAN program is given.

This study has been conducted to investigate the genetic and ecological variation of wheat culm length measured from those plants grown at greenhouse. The results are as following. 1. The clum length of the winter wheat was higest under 12hrs daylength, while that of the spring wheat was highest under 8hrs daylength. Standard errors of culm length was larger under 12 and 8hrs daylength than that of 24hrs daylength condition. 2. The culm length was shortest under the 24hrs daylength compare to under 12 or 8hrs while it was highest under 12hrs. Short and medium culm length varieties were photo-insensitive but those of long culm length were photo-sensitive. 3. There are many types of varietal differences for the culm length under the daylength conditions. Highest culm length group under 12 and 8hrs conditions was classified. The semi-dwarf varieties that did not change their plant heights under i and 12hrs conditions were Hira, Yecora Resel, Sava, Sturdy, Saric 70, Sekidorisai 66etc. 4. Varietal difference of culm elongation was noticed between 8hrs and 12hrs daylength condition. On the basis of the evidences obtained from this experiment, it may be concluded that the genetic studies related to culm length should be carried out under the most favorable conditions for culm elongation. 5. Correlation coefficients estimated between culm length and heading or maturity were negative but insignificant, but their correlations were highly significant between photo treatments. 6. Culm length of F_1 was intermediate to the range of F_2 population which seems to be distributed normally. In this regard the gene involved with culm length seemingly inherit additively. Statistical analysis for the involved genes for culm length suggested 2 genes for the semidwarf variety Robin #2.

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

It is recognized that reinforcement corrosion is the main distress behind the present concern regarding concrete durability. In this study, to confirm corrosion of reinforced concrete due to permeability of carbonation and chloride ion affected by thickness of cover, kinds of surface coating, measured electric potential, ratio of corrosion area, weight reduction, corrosion velocity of steel bar under environment of complex deterioration. The results showed that an increase in age also decreases Carbonation velocity coefficients and increases Chloride ion diffusion coefficients. As well, an increase in age also increases corrosion of reinforcement due to permeability of carbonation and chloride ion. Corrosion of reinforcement by thickness of cover is superior to 10mm thick than 20mm thick. It showed that an increase in thickness of cover prevent steel bar from deteriorating due to permeability of carbonation and chloride ion. The results of this study showed that corrosion velocity was affected by thickness of cover, kinds of surface coating. data on the development of corrosion velocity made with none, organic B, organic A, inorganic B. and inorganic A is shown.

The aim of study was to investigate genetic diversity for the calpain/calpastatin gene in three Hanwoo breeds [(Brown (n=62), Brindle (n=81) and Jeju Black (n=30)]. Random samples from three breeds of Hanwoo were selected and genotyped for the 7 SNPs of calpain/calpastatin using TaqMan method. Allele frequencies were investigated for CAPN1/CAST gene. Allele frequency of CAST2 SNP was 0.75, 0.59 and 0.22 for Brown, Brindle and Jeju black, respectively. The CAST3 revealed allele frequency of 0.59 and 0.57 in Brown and Jeju Black, while it showed very low allele frequency (0.07) in Brindle. In particular, favorable allele (G allele) for the CAPN1-2 SNP which was shown a strong association with tenderness in Taurine and Indicine cattle revealed 16% and 17% higher allele frequency in Brown Hanwoo (0.82) comparing Brindle (0.66) and Jeju Black Hanwoo (0.65). AMOVA demonstrated that among population variance occupied only 10% of total variance and among individual variance was 0%, while within individual variance was 90% of total variance. This result showed that population effect contributed very small portion of genetic to these three Hanwoo breeds, while within individual variance contributed large portion of genetic diversity within these Hanwoo breeds. In conclusion, three Hanwoo breeds (Brown, Brindle and Jeju black) showed a genetically homogeneous based on the 7 SNPs of CAPN1/CAST gene and it came from same ancestor to form modern Hanwoo breed.
