Studies on the effect of different secondary nutrients in different doses on the leaf yield and biochemical constituents of Terminalia tomentosa revealed that secondary nutrients have promotary effect in increasing the leaf yield and foliar constituents of Terminalia tomentosa. Among all the treatments under study, foliar application of magnesium sulphate (2g/plant, w/v) is the best in respect of leaf yield and biochemical constituents of T. tomentosa. This treatment gave 29.15% increase in leaf yield over control. Chemoassay results further confirmed significant improvement in biochemical constituents. Except crude fibre, moisture, minerals, crude protein and total carbohydrate increased significantly over control.

An animall health monitoring system in Gyeongnam area(near Chinju) was studied to analysis of biochemical risk factors in 617 herds. Clinical serum factors such as glutamate oxaloacetate transaminase(GOT), glutamate pyruvate transaminase(GPT), Ca, P, Mg, glucose, and cholesterol were measured with automatic biochemical analyzer(Ra-X7T Techmmicon, USA). In serum analysis, 613 cattle were within normal llimits(GOT: 9.5-85 IU-dl, GPT: 25-77IU/dl, total protein: 5.8-8.5g/dl, Ca: 4.2-12.4mg/dl, P: 4.6-9.7mg/dl, Mg: 1.5-3.0mg/dl, glucose: 48-120mg/dl, Cholesterol: 70-170mg/dl), the other cattle showed high glucose and high cholesterol level. It is proposed that clinical serum factors to be estimated may be valuable for developing of animal health monitoring system model.

The present study was conducted to investigate biochemical properties and antimicrobial drug susceptibilities of 36 strains of Pasteurella haemolytica(P haemolytica) isolated from pneumonic calves in Kyongbuk province during the period from January 1990 to December 1990. P haemolytica was isolated from 36 of 111(32.4%) pneumonic calves of 1 to 6 months of age. The majority of biochemical and cultural properties of P haemolytica isolated from calves were identical to those of the reference strains employed. All isolated were susceptible to baytril, gentamicin, and kanamycin, some of them were resistant to tetracycline, amikacin, streptomycin, and ampicillin.

Aqueous fractions from Korean red ginseng inhibited the phosphorylations of 40 KD and 20 KD polypeptides which were induced by phorbol-12-myristate-13-acetate (100 nM) in human platelets. Much more carbohydrates were contained in the aqueous fractions than proteins. An aqueous fraction extracted with methanol, mainly, consists of glycoproteins, molecular weights of which were below 18 KD. We may infer that the aqueous fraction from Korean red ginseng do antitumorous and antiplatelet functions.

In this study, the silicone thermal curing degree of the silicone-encapsulated quantum dot light emission diode was measured using the various types of chemical ligands around quantum dot. It was confirmed that the trioctyl phosphin oxide (TOPO) ligand around the quantum dot was responsible for dispersion of the quantum dot in silicone encapsulant and decline of the thermal curing degree of the silicone encapsulant. Also, it was confirmed that the thermal curing degree of silicone encapsulants containing the steric acid (SA) and the dodecanoic acid (DA) ligands were higher than the one of TOPO ligand.

Recently sewage facilities mainly consisted of concrete structures are being deteriorated seriously by biodeterioration originated from sulfur-oxidizing bacteria. To prevent biochemical corrosion of the sewage concrete, antibiotics which prevent growth of sulfur-oxidizing bacteria were developed. Existing methods to evaluate properties of biochemical corrosion of concrete examine the antimicrobial performance and resistance to sulfuric acid separately, but don't complexly. So, in this study, new method to test properties of biochemical corrosion of concrete complexly is suggested.

Recently sewage facilities mainly consisted of concrete structures are being deteriorated seriously by biochemical reaction originated from sulfur-oxidizing bacteria. To prevent biochemical corrosion of the sewage concrete, antibiotics which inhibit growth of sulfur-oxidizing bacteria have to be developed and applied necessarily. In this study, we are going to introduce technology which biochemical corrosion of sewage facilities concrete could be controlled effectively by antibiosis of antimicrobial concrete

Lipomyces starkeyi KSM 22 elaborates an enzyme that has both dextranase and amylase activities in a single protein of 100 kDa. Competition studies, using different amounts of dextran and starch as substrates, gave a competition plot consistent with the hypothesis that the hydrolysis of dextran and starch occurs at two independent active sites, each specific for starch and dextran, respectively.

We have isolated endophytic fungi from the Indian yew tree, Taxus baccata, and then screened for taxol production. Out of the 40 fungal cultures screened, one fungus Gliocladium sp. was found to produce taxol and 10-DABIII (10-deacetyl baccatin III). These compounds were purified by TLC and HPLC and characterized using UV-spectroscopy, ESI-MS, MS/MS, and proton NMR. One liter of Gliocladium sp. culture yielded $10\;{\mu}g$ of taxol and $65\;{\mu}g$ of 10-DABIII. The purified taxol from the fungus showed cytotoxicity towards cancer lines HL-60 (leukemia), A431 (epidermal carcinoma), and MCF-7 (breast cancer).

The present study was conducted to investigate the biochemical and cultural characteristics of Escherichia coli isolates from clinically affected chickens during the period from May 1988 to June 1989. A total of 82 E coli cultures were isolated from lesions of 75 chickens with colisepticemia. Biochemical properties of E coli isolates tested were in accordance with the general classification standard; all the isolates showed positive reaction in Catalase, Indol, and Methyl-Red tests, but negative reaction in Oxidase, Urease, $V{\ddot{o}ges$-Proskauer, Citrate utility, $H_2S$, Phenylalanine diaminase, and malonate tests. And the carbohydrate fermentation rates of them were shown to be variable. of the 82 isolates, 48(58.5%) cultures produced colicin to inhibit the indicator strain of E coli.
