In our search for natural products affecting blood circulation, the n-butanol fraction from whole plant of Glehnia littoralis Fr. Schm. (GLB) improved blood lipid parameters, and ameliorated obesity in high-fat-diet (HFD)-fed C57BL/6 mouse model. Hyperlipidemia was induced by high-fat-diet for 4 weeks, and then GLB was orally administrated with 400 mg/kg/day for 4 weeks. GLB-treated group showed that the gain in body weight was significantly attenuated, the levels of total cholesterol and triglyceride significantly lowered on blood chemical analysis, and significantly prolonged the mice bleeding time when compared with those of HFD control group. Concomitantly, phytochemical composition of GLB was investigated by HPLC-hyphenated spectroscopy, and two major phenolic compounds, rutin and chlorogenic acid were identified in the GLB. Taken together, these results indicate that GLB has cardiovascular protective effects and could be a natural medicine candidate for the prevention of cardiovascular disease.

Olive flounder was treated with oxytetracycline (OTC) and changes in blood physiology, antioxidant enzymes and heat shock protein (HSP) were recorded to obtain preliminary data for optimal OTC treatment. Blood parameters were measured 1 and 3 h after the OTC treatments at the concentration of 0 (control), 100, 300 and 500 ppm for I h. Hematocrit decreased with time, however the difference was not significant (P>0.05). Reduced number of red blood cell was observed with increasing OTC concentration. Serum glucose level increased as the OTC concentration increased. However, glucose level was similar to control after 3 h. Blood total protein decreased immediately after the OTC treatment but increased after 1 and 3 h. However, the increment in blood total protein was low. Activities of superoxide dismutase enzymes in 300 and 500 ppm groups increased by the OTC concentration. Catalase enzyme activity was negatively affected by the OTC concentration. However, the differences were not significant (P>0.05). High expression of HSP-70 protein was recorded for groups treated with 100 and 500 ppm compared to that of the control group. However HSP-70 mRNA showed a lower increment which was not significant (P>0.05).

Bioequivalence of two clarithromycin tablets, the $Klaricid^{TM}$ (Ciba-Geigy Korea Ltd., Seoul, Korea) and the LG clarithromycin (LG Chemical Co., Ltd., Seoul, Korea), was evaluated according to the Korean Guidelines for Bioequivalence Test (KGBT 1998). Sixteen normal male volunteers $(20{\sim}26\;years\;old)$ were randomly divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After one tablet containing 250 mg of clarithromycin was orally administered, blood sample was taken at predetennined time intervals, and the concentrations of clarithromycin in serum were detennined using HPLC method with electrochemical detector. The pharmacokinetic parameters $(AUC_t,\;C_{max}\;and\; T_{max})$ were calculated and ANOVA was utilized for the statistical analysis of parameters. The results showed that the differences in $AUC_t$, $C_{max}$, and $T_{max}$ between two tablets based on $Klaricid^{TM}$ tablet were 4.06%,2.67% and -9.70%, respectively. The powers $(1-{\beta})$ for $AUC_t$, $C_{max}$ and $T_{max}$ were 83.53%, 92.34% and 96.64%, respectively. Detectable differences $({\Delta})$ and 90 % confidence intervals $(a=0.05) $were all less than ${\pm}20%$. All the parameters above met the criteria of KGBT 1998, indicating that LG clarithromycin tablet is bioequivalent to $Klaricid^{TM}$ tablet.

The purpose of this study was to obtain reference data of parameters for hematological health diagnosis in marine fish and also evaluate application of veterinary chemistry analyzer used to those blood tests. A blood profile of total 522 fish for black rockfish (Sebastes schlegeli), red seabream (Pagrus major), rock bream (Oplegnathus fasciatu) and black seabream (Acanthopagrus schlegeli) cultured in mari-floating netcage of Gyeongnam province was determined by hematocrit (Ht), hemoglobin (Hb) and blood chemistry tests (total protein, albumin, alkaline phosphatase, blood urea nitrogen, lactate dehydrogenase, triglyceride, total cholesterol, creatinine, aspartate aminotransferase, alanine aminotransferase, glucose). Ht was measured by microhematocrit method. Hb and plasma chemistry were analysed by establishing baseline ranges for a dry chemical system of FUJI DRI-CHEM 3000. Actually recorded values of Hb and plasma chemistry by the analyzer were notably outside from the minimum and/or maximum of the established reference value. Albumin and alanine aminotransferase were not detectable in the range of 68～66%. Lactate dehydrogenase, total protein, alkaline phosphatase and glucose were not detectable in the range of 42～21%. Total cholesterol, aspartate aminotransferase, triglyceride, hemoglobin and creatinine were not detectable in the range of 18～3%. However, the values of blood urea nitrogen were below the detectable limits of the analyzer.

Purpose : We compared body growth, blood cell counts, and chemistry among infants receiving soy-based formula (SF), breast milk (BM), and casein-based formula (CF). Methods : Full-term neonates delivered at our hospital from June 2001 to August 2003 were recruited and divided into 3 feeding groups (BM=20, SF=19, CF=12 ) according to the parents wishes. Breast feeding or artificial formulae were given during the initial 3 months of age; thereafter, weaning foods were added freely. Height, weight, head circumference, skin-fold thickness, and mid-arm circumference were measured at birth and 1, 2, 4, 5, 12, and 36 months of age. Cell counts and blood chemistry were analyzed at 5, 12, and 36 months of age. Result : At 5 months of age, body weight was the lowest in the SF group; the height was similar among all groups. Thereafter, there were no differences in height or weight among the groups until 36 months of age. Hemoglobin was the lowest in the BM group at 5 and 12 months of age (P< 0.05 ). At 5 months of age, serum cholesterol, BUN, phosphates, and K+ were significantly lower in the SF group; thereafter, all chemical parameters were similar until 36 months of age. Conclusion : Infants fed with SF showed normal growth during the first 3 years of life as compared to infants fed with BM and CF. Low values of serum phosphates and K+ at 5 months of age in the SF group, despite the high mineral content, suggest that further investigation is needed for effective mineral absorption.

The purpose of this study is to investigate toxic effects of iso-butylalcohol (iBA) in Sprague-Dawley (SD) rats under the exposure of 6 hours a day, 5 days a week for 13 weeks by inhalation, and to evaluate the occupational safety of iBA in comparison with the permissible exposure level (PEL) stipulated by the Occupational Safety and Health Administration (OSHA). iBA did not induce any abnormal changes from the aspects of clinical signs, feed consumption, ophthalmic test, urinalysis, hematology and blood chemistry during and at the terminal of the inhalation toxicity tests. We did not find any abnormal findings in the gross and microscopic observations due to the inhalation of iBA. There was no alteration in relative organ weights by the inhalation of iBA. No observed adverse effect level (NOAEL) of iBA was considered to be more than 3,000 ppm in rats under the inhalation of 6 hours a day, 5 days a week for 13 weeks. Fifty ppm of iBA, the PEL regulated by OSHA, is too conservative for working places. As iBA showed no abnormal observations in all the experimental parameters at any concentration under this experimental condition, we suggest that 150 ppm is safe enough for the PEL of iBA in the working areas, even taking into onsideration that OSHA lowered the PEL to 50 ppm for fear of the probable risk of its skin irritation.

The object of this study was to examine whether the germanium fortified yeast administered to SD rat is accumulated in the liver and kidney. The administration doses were within 2,000 mg/kg which is the level of NOAEL (no observed adverse effect level) proved through the previous study of single/consecutive oral toxicity test. There were no significant clinical symptoms and mortality following the administration of organic germanium-fortified yeast (0, 500, 1,000, 2,000 mg/kg) during the whole test period, and also no difference in the consumed amount of feed and water for each group. No significant abnormalities of hematology and blood chemistry parameters were found in all groups of organic germanium-fortified yeast (0, 500, 1,000, 2,000 mg/kg). The amount of germanium accumulated in liver and kidney was 0 g/kg by ICP-AES method in the group of organic germanium-fortified yeast. In the positive control group of $GeO_2$ (150 mg/kg), the amount of accumulation was shown to 3135.0 and 4277.2 g/kg in each female and male kidney and 1044.3 and 2135.8 g/kg in each female and male liver, respectively. Organic germanium-fortified yeast, a biosynthetic product resulting from putting germanium into yeast, did not show any clinical symptoms, blood chemical significance, and residues in kidney and liver. It could be inferred that the non-toxic amount of organic germanium-fortified yeast was up to 2,000 mg/kg.

Natural mineral water is generally quite different from ordinary drinking water due to its original nature and various properties. The complexity of natural mineral water requires, therefore, not only to identify its nature and proper characteristics, but also to classify them by a reasonable scientific basis of comparison. The study was concentrated on a possible classification technique to natural mineral waters by their constitutions and physico-ehemical properties. The classification was carried out by the computation of such numerical parameters as ionic equivalent percentage, electrolytic conductance or mobility, ionic molecular weight, molecular concentration, equivalent conductivity and degree of ionization in consideration of the determinative criteria as follows -particular single element or molecule -major components of natural waters as bicarbonate, sulphate, chloride,caloride, calcium, magnesium, and sodium -moleculat concentration related to blood osmotic pressure -water temperature at emergence from spring -contents of free carbon dioxide (CO2) -pH value of water -total dissolved solids or salts (NaCl) The results obtained proved out to be clearly distinguhhable from ordinary drinking water as far as concern natural mineral water as an example on the subject -simple water -bicarbonate-predominating water -cold spring -carbonated-non gaseous water -weak alkaline water -non saline water Putting these various results together, the sample turned out to be a kind of natural mineral water that can be used as a drinking water if microbiologically safe.

In India, Gymnema sylvestre due to the unique property of the plant to antagonize the sweet taste is known as 'Gur-mar'. It has several ethnomedicinal values as various tribals/traditional communities and rural peoples of India find diverse medicinal uses viz. antidiabetic, stomachic, diuretic, and is useful in cough and throat troubles. Besides, it has strong effect on reducing blood sugar. The present communication deals with the detailed pharmacognostical evaluation of the aerial parts of G. sylvestre collected from three places of the country-Varanasi (U.P), Panchmarhi (M.P), Salem (Tami Nadu) and commercial sample procured from local market. The botanical and physico-chemical parameters of all the samples were quite similar though little variations were observed in foaming index, alcohol and water soluble extractives of local sample. The microscopic characteristics of the drug are horse shoe shaped petiole with 3 amphicribal vascular bundles, sieve tubes well developed; anomocytic stomata only on the abaxial surface of the leaf, the fan shaped amphicribal vascular bundle, presence of intraxylary phloem. The TLC fingerprint profile of all the samples was more or less similar only the quantity of some of the compounds varied.

Lidocaine and galactose loading tests were performed on a bioartificial liver (BAL), an extracorporeal medical device incorporating living hepatocytes in a cartridge without a transport barrier across the membranes. The concentration changes were analyzed using pharmacokinetic equations to evaluate the efficacy and limitation of the proposed method. Lidocaine and galactose were found to be suitable drugs for a quantitative evaluation of the BAL functions, as they did not interact with the plasma proteins or blood vessels, making their concentrations easy to determine. The drug concentration changes after drug loading were easily analyzed using pharmacokinetic equations, and the BAL functions quantitatively expressed by pharmacokinetic parameters, such as the clearance (CL) and galactose elimination capacity (GEC). In addition, these two drugs have already been used in clinical tests to evaluate human liver functions over long periods, and lidocaine CL values and GEC values reported for a normal human liver. Thus, a comparison of the CL and GEC values for the BAL and a natural liver revealed what proportion of normal liver functions could be replaced by the BAL.
