The extraction yield of the methanolic extracts and 19${\alpha}$-hydroxyursane-type triterpenoid (19${\alpha}$-HUT) fraction were investigated in the unripe and ripe fruits and the leaves of the four Rubus plants (Rubus coreanus, R. crataegifolius, R. phoenicolasius, R. pungens var. oldhami) to develop the biomaterial 19${\alpha}$-HUT mixture as functional foods. Thin layer chromatogaphy-Densitometer (TLC-DM) was used to analyze the individual quantity of 19${\alpha}$-HUTs using standard compounds (euscaphic acid, tormentic acid, 23-hydroxytormentic acid, kaji-ichigoside F$_1$, rosamultin, niga-ichigoside F$_1$). The content of methanolic extract of the fruits were higher in the ripe stage than in the unripe stage whereas the content of 19${\alpha}$-HUT mixture varied with each Rubus species. The Rubus plants containing the highest amount of 19${\alpha}$-HUTs in the leaves were R. coreanus, R. phoenicolasius and R. pungens var. oldhami while only R. cratagefolius showed the highest content in the ripe fruits. The mean of total genin content of 19${\alpha}$-HUTs was 0.94 mg/g; that of the glycosides was 0.60 mg/g. The genin quantity was found in the order of 23-hydroxytormentic acid> euscaphic acid> tormentic acid; the glycoside was observed in the order of niga-ichig-oside F$_1$> kaji-ichigoside F$_1$> rosmaultin, by which the biosynthetic pathway of 23-hydroxytormentic acid and its glucoside niga-ichigoside F$_1$ via the intermediates tormentic acid and/or rosamultin was presumed. It is also suggested that the ripe fruits of R. crataegifolius will be desirable to use as functional foods rather than unripe fruits.

The comopositon of lipids extracted from corn embryo with various solvents were analyzed. The solvents for the extraction were benzene(BZ), n-hexane(HX), pet. ether(PE), trichlorethylene (TE), chloroform-methoanol(2:1, v/v) (CM), dichlormethane - methanol(2:1, v/v)(DM) and hexanediethyl ether(5:1, v/v)(HD). The lipids were than fractinated by silicis acid column chromatography(SACC) into three lipid fractions. The Neutral lipid fractons were further separated by thin layer chromatography(TLC) and the individual lipid spots were quantitatived by TLC scanner. And then the fatty acid compositions of total lipids and neutral lipids were determined by gas chromatography(GC). Crude oil contents of corn embryo were most efficient by using DM, CM and neutral lipid was extracted much HX, BZ, HD systems than did PE, DM, DM an CM were most efficient solvent systems for extracting glycolipid and phospholipid. The major component of the neutral lipid fractions was found to be triglyceride, and it was superior DM to PE. Linoleic acid was the predominant fatty acid in the total lipids, and it was most efficient with BZ and TE. The major fatty acid in neutral lipids was also linoleic acid and it was superior BZ to PE, CM, HD and oleic acid was similar to seven solvents and palmitic acid was found much superior in using CM.

Purpose: The present study was conducted to evaluate the impact of scaling and root planing (SRP) on the C-reactive protein (CRP) levels of gingival crevicular fluid (GCF) and serum in chronic periodontitis patients with type 2 diabetes mellitus (T2DM-CP) or without type 2 diabetes mellitus (NDM-CP). Methods: Forty-eight human participants were divided into two groups: an experimental (T2DM-CP) group (group I, n=24) comprising chronic periodontitis patients with random blood sugar ${\geq}200mg/dL$ and type 2 diabetes mellitus, and control (NDM-CP) group (group II, n=24) of those with chronic periodontitis and random blood sugar <200 without T2DM for the study. All subjects underwent nonsurgical periodontal therapy (NSPT) including complete SRP and subgingival debridement. Periodontal health parameters, plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), GCF volume (GCF vol), GCF-CRP, random blood glucose (RBS), glycated hemoglobin, and systemic inflammatory markers, serum CRP, total leukocyte count (TLC), neutrophil count (Neutr) and lymphocyte count (Lymph), were evaluated at baseline, 1 month, and 3 months after SRP. Results: NSPT resulted in statistically significant improvement in periodontal health parameters (PI, GI, PPD, CAL, GCF vol), CRP levels in serum as well as GCF of both groups I and II. The mean improvement in periodontal health parameters (PI, GI, PPD, CAL, GCF vol), CRP levels in serum and GCF was greater in group I than group II after NSPT. There was nonsignificant increase in GCF-CRP, TLC, Lymph, and RBS, and a significant increase in Neutr and Serum CRP in group II at 1 month. The Serum CRP level of 20 out of 24 group II patients had also increased at 1 month. Conclusions: The CRP levels in both GCF and serum were higher in T2DM-CP patients than in NDM-CP patients. Although there was a significant improvement in both the groups, greater improvement was observed in both GCF and serum samples of T2DM-CP patients.

In order to investigate polar lipid ingredients and fat쇼 acid compositions in corn embryo, lipids were extracted with n-hexane (HX), pet. ether (PE), chloroform-methanol (2:1, v/v) (CM), dichoromethane-methanol (2:1, v/v DM) and hexane-diethyl ether (5:1, v/v HD). Of the glycolipid in polar lipids were separated by thin layer chormatogarphy (TLC), monoglycosyl diacyglycerol was most efficient with CM, HD, and monoglycosy sterol and monoglycosyl ceramide were similar to five solvents, but HX, PE and DM, HD were somewhat superior, respectively. Of the phospholipid, phosphatidyl inositol was most efficient with CM, DM, and phosphatidyl choline was similar to five solvents as well. Phosphatidyl serine was superior PE, HD, CM to HX, and phosphatidyl ethanolamine was inferior CM to HX. The major fatty acid in the glycolipid was linoleic acid, and it was most efficient with CM the same as plamitic acid, but oleic acid was superior in using HX, PE. The major fatty acids in the phospholipid were palmitic, heptadecanoic aicds, and they were superior in using HX and PE, respectively. Also oleic acid was most efficient with HX and CM, but HD was somewhat inferior.

Sulforhodamine B (SRB) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, RNA dot blot and Northern hybridization analysis were performed to screen microorganisms for the production of anticancer agent. Among microorganisms tested, strain YP-1 was selected for its cytotoxicity and ability to reduce the level of c-myc RNA. Strain YP-1 was identified as Streptomyces endus. The anticancer material produced by Streptomyces endus YP-1 was sequentially purified by solvent extraction, silica gel column chromatograpby, preparative TLC and preparative HPLC. The cancer material identified as azalomycin B by the instrumental analyses such as $^{1}$H-NMR, $^{13}$C-NMR, Mass, IR and UV absorption. It was colorless amorphous powder and its molecular weight was 1025.278. Azalomycin B, produced by Streptomyces endus YP-1, showed anticancer activity against several human cancer cell lines and reduction of c-Myc protein level in Colo320 DM cells which was determined by Western blot analysis.

Twenty eight 3-4 month old castrated Black Bengal kids (Capra hircus) were used to determine the effects of source and level of dietary copper (Cu) concentration on their performance and nutrient utilization. Cu was supplemented (0, 10, 20 and 30 mg/kg diet DM) as copper sulfate ($CuSO_4$, $5H_2O$) or copper proteinate (Cu-P). Kids were fed a basal diet containing maize (19.5%), soybean (17.0%), deoiled rice bran (56.5%), molasses (4.0%), di-calcium phosphate and salt (1.0% each) and mineral and vitamin mixture (0.5% each) supplements at 3.5% of body weight to meet NRC (1981) requirements for protein, energy, macro minerals and micro minerals, excluding Cu. The basal diet contained 5.7 mg Cu/kg, 122.5 mg Fe/kg, 110 mg Zn/kg, 0.26 mg Mo/kg and 0.32% S. $CuSO_4$ or Cu-P was added to the basal diet at the rate of 10, 20 and 30 mg/kg. Kids were housed in a well ventilated shed with facilities for individual feeding in aluminum plated metabolic cages. Blood samples were collected from the jugular vein on d 0, 30, 60 and 90 to determine hemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), total leukocyte count (TLC) and serum enzymes (alkaline phosphatase, alanine transferase and aspertate transferase). A metabolism trial of 6 days duration was conducted after 90 days of experimental feeding. Statistical analysis revealed that source and level of Cu supplementation improved live weight gain (p<0.04) and average daily gain (p<0.01). No significant contribution of source and level of Cu to alter serum serum enzymes was evident. Goats fed Cu-P tended to have higher Hb, PCV and TEC than with $CuSO_4$ supplementation. Cu-P increased digestibility of ether extract (EE, p<0.02) and crude fiber (p<0.05) and showed an increasing trend (p<0.09) for digested crude protein (CP) and crude fiber (CF). Supplemental dose of Cu linearly improved (p<0.02) digestibilities of dry matter (DM), organic matter (OM), EE and nitrogen free extract (NFE). Though the absorption of nitrogen (N) was not affected (p>0.10) by both source and dose of Cu, N retention was affected (p<0.04) and there was a significant $Source{\times}Dose$ interaction (p<0.05). Final body weight (BW) was not influenced (p>0.10) by the source of Cu but increasing dose of Cu increased (p<0.04) the BW of kids. TDN intake (g/kg $W^{0.75}$) was higher (p<0.05) with the increased dose of Cu and there was a significant $Source{\times}Dose$ interaction. It was concluded that supplementation of Cu from different sources and varying dose level in a concentrate based diet may improve performance, nutrient utilization and plane of nutrition in castrated Black Bengal kids. The effects on performance and nutrient utilization are more pronounced with Cu-P than $CuSO_4$ supplementation. Higher dose of Cu showed better result than lower dose.

The present investigation was designed to determine whether supplementation of different level of vitamin E for 12 months to arsenic exposed goats (50 ppm as sodium arsenite) affords protection against the blood hemato-biochemical parameters caused by the metalloid. A total of 24 crossbred (Alpine${\times}$Beetal) lactating goats were assigned randomly into 4 equal groups (control, $T_1$, $T_2$ and $T_3$) of 6 in each, on the basis of average body weight ($36.10{\pm}0.11$ kg) and milk yield ($1.61{\pm}0.04$ kg/d). The animals in $T_1$, $T_2$ and $T_3$ were given 50 ppm arsenic, while in $T_2$ and $T_3$, additionally; vitamin E at the rate of 100 IU and 150 IU/kg dry matter (DM) respectively was additionally supplemented for the period of 12 months. Hemoglobin (Hb), total leukocyte (TLC) and blood lymphocyte % were decreased (p<0.05) in arsenic fed groups and vitamin E supplementation in the experimental group showed a protective potential. Significant increases (p<0.05) in aspertate transaminase (AST) and alanine transaminase (ALT) activities among arsenic supplemented groups were recorded, however vitamin E supplementation at higher doses showed a protective effect (p<0.05) against AST but in the case of ALT no ameliorating effect was found in either of the doses. Plasma total protein was decreased (p>0.05) but creatinine level was periodically increased in all As supplemented groups and vitamin E supplementation did not produce any protective effect. It can be concluded that arsenic exposure resulted in varying degree of changes in hemato-biochemical parameters and activities of antioxidant enzymes in goats but concomitant treatment with Vitamin E is partially helpful in reducing the burden of arsenic induced effect.
