To develop a cotton derivatives with prolonged antimicrobial activities, homosulfamine (Hs) was coupled to cotton xanthate (CX) via chelate bond in the presence of Cu(II) ion by one- and two-bath processes. In one-bath process, CX was treated with Cu(II)-Hs solution. In two-bath process, CX was treated with Cu(II) ion solution to produce CX-Cu(II) complex, which was isolated and treated in turn with Hs solution. Effects of concentration, Cu(II)/Hs ratio, and pH on the binding of Hs were investigated at $10{\circ}C$ . In one-bath process, binding of hs took place readily with optimum pH around 5-6. the amount of binding increased to give a maximum within 5 min and decreased slowly to establish an equilibrium withhin an hour. In two-bath process, binding of Hs was much lower than that of one-bath process. Release of Hs from CX-Cu(II)-Hs was investigated by batch and flow method. antimicrobial activiteis of CX-Cu(II)-Hs was investigated by batch and flow method. Antimicrobial activities of CX-Cu(II)-Hs were tested against Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli and it showed prolonged activity compared to that of free Hs.

Daidzein and its methyl derivatives were synthesized and their anti-inflammatory activities were examined. Daidzein suppressed the carrageenin-induced edema, but its methyl derivatives showed decrease or abolition of the anti-inflammatory effect. Daidzein did not significantly suppress the complete Freund's adjuvant-induced arthritis, and the mixed phlogistics (histamine+serotonin)-induced edema. Daidzein inhibited the leukocyte emigration and protein exudation when it was administered into the CMC pouch at low doses (5,25mg/pouch). Daidzein significantly suppressed the cotton-pellet granuloma formation.

The present study investigated the antitumor activity of the aqueous-alcoholic extracts from unripe cotton balls of Gossypium indicum. An Exposure of murine B16 melanoma and L1210 lymphoma cells to the extracts resulted in their severe deaths in time- and concentration-dependent manners. Of the extracts, hydrophilic fractions were most efficacious for the antitumor activity and found to contain certain amounts of catechin and its derivatives. The hydrophilic extract fraction C36B2-8 had approximately 10 times more cytotoxic effects on B12 and L1210 cells than on isolated murine thymocytes. High concentrations (>150 $\mu$g/ml) of C 36B3-8 mainly induced necrotic cell death. At low concentrations (<100 $\mu$g/ml), however, C 36B3-8 induced not only necrosis but also apoptosis of the two tumor cell lines, which was proved by the TUNEL staining and DNA fragmentation techniques. The data indicate that certain ingredients of the cotton ball extract of G. indicum have an antitumor activity.

Allantoin and uric acid were estimated in milk to study the association between the levels of these purine derivatives and milk production per day under given feeding regimens. Keeping the stage of lactation, parity and initial milk yield in view thirty lactating buffaloes were randomly selected from early lactating group. All the animals were fed 30 kg green, 2 kg straw and 5 kg concentrate mixture on per animal/day basis at basal level up to 8 1 produce. 1 kg concentrate mixture, soaked cotton seed and boiled cotton seed was fed for every 2 I milk, respectively in Group I (control), Group II and Group III animals. Average milk Allantoin and Uric acid levels were $120{\pm}11.7g/ml$ and $4.03{\pm}0.63g/ml$, respectively in milk. Cotton seed feeding enhanced the milk production significantly (p<0.01) in comparison to concentrate mixture fed control group animals. A significant difference (p<0.01) in milk allantoin levels was found over the different feeding management at higher level of production group animals. Study also revealed a significant negative correlation between the milk allantoin and production per day r=-0.43 (p<0.05).

To study the printing behaviors of Polyester and cotton(P/C) fabrics printed with disperse and reactive dyes, the effects of alkalis on the fixation of reactive dyes and the alkali-stability of disperse dyes in various methods of fixation were examined. The anthraquinone disperse dyes which have diamino derivatives as substituents without hydroxy group, such as C.I. Disperse Violet 1(D.V.1), C.I. Disperse Violet 28(D.V.28) and C.I.Disperse Blue 60(D.B.60) showed good results of fixation without regard to the concentration of NaHCO$_3$. In case of high temperature steaming(HTS) and unsaturated steaming(US)/HTS, D.V. 1 was alkali-stable and effective for P/C printing. A good result was obtained with D.V.1 and C.I.Reactive Orange 13(R.O.13) paste of 4% $K_{2}CO_{3}$. It was found that the unfixed D.V.28 bearing chloro group can hinder the fixation of monochlorotriaxinyl reactive dyes, and D.B.60 made little stain on 100% cotton. In thermosol(Tm), the dye uptake of D.V.1 was not decreased so much, but those of D.V.28 and D.B.60 were greatly decreased.

Natural colorants haute attracted much attention all over the world because of their non-hazardous nature. The world is becoming increasingly aware of environmental Issues, such as ozone layer depletion, water pollution and waste disposal problems. The use of synthetic dyestuffs for their synthesis and application in the dyeing industries has been criticized due to introduction of contaminants into the environment. This has led to the desire to turn to the traditional, and more natural way of life. In this study, the colorants of extract of Ginkgo biloba bark were analysed and their dyeing properties on silk, wool and cotton were studied. It was found that uv-visible absorption spectra of extract of Ginkgo biloba bark showed two strong absorption Peaks in the range of 240 ∼400 In. From the result of IR spectra, the major ingredient of extract of Gikgo biloba bark seems to be the flavon which is one of the flavonoid derivatives. Silk, wool, and cotton dyed with the extract of Ginkgo biloba bark showed a reddish yellow color. Their color differences were increased drastically with repetition of dyeing by three times.

The enzyme-like catalytic functions of metal complex phthalocyanine derivatives those containing carboxylic acid groups could be applied as odor-removing systems and antibacterial systems. Pyromellitic dianhydride and 4-nitrophthalimide were used as starting material for synthesizing dinitro-tetracarboxylic acid iron phthalocyanine(compound 1). Then diamino-tetracarboxylic phthalocyanine(compound 2) was obtained by reduction of compound 1. For the formation of covalent bond with cellulose fiber, cyanuric chloride was introduced to the amino group of compound 2 by condensation reaction compound 3. The exhaustion method was employed for adsorbing compound 3 on cotton fiber. K/S values of each fabrics were measured by a CCM system and deodorizing rates were tested by a detector tube method for ammonia gas. K/S values of treated cotton fiber with compound 3 were arranged from 2.1 to 4.2 at $90^{\circ}C$ of exhaustion temperature. Deodorizing rates provided result of 81%, 84%, 88%, 91%, by passing time of 30 min, 60 min, 90 min, 120 min, respectively.

The azo red pigments for textile printing containing amino-N-substituted benzamide derivatives as diazo components and 2-hydroxy-3-naphthoyl derivatives as coupling components were prepared. They have been printed on cotton, and the fastness, such as light, washing, dry cleaning, rubbing and heat stability was estimated. The new azo red pigments were valuable colorants in case of textile printing.
