Carbon tetrachloride ($CCl_4$) has been used to treat a variety of parasitic infection in both large and small animals, including Fasciola hepatica. Recently, we can easily contest with carbon tetrachloride in air, food, water, rain and Industry area etc. and it is using in order to induce liver injury in laboratory. In this study. we investigated activitis of LDH, ALP, AST and ALT and amount of cholesterol, triacylglycerol, glucose and BUN in mice serum exposed to $CCl_4.$ The mice divided Into a Naive control(A), corn oil control(B) and experimental group(C, D). Naive control group(A) was given feed and water only. Corn oil control group(B) was given corn oil 1ml /100g of body weight(B.W). Experimental group(C) was given carbon tetrachloride 1ml /100g B.W. ($CCl_4$： corn oil=1：20(V /V) ), Experimental group(D) was given carbon teterachloride 1ml /100g B.W. ($CCl_4$: corn oil=1：10(V /V) ). The results obtained were summarized as follows : 1) The body weight was declined after the l0th day In mice exposed to carbon tetra-chloride. 2) The total protein level in serum was significantly in mice exposed to carbon tetra-chloride($P{\leq}0.05$). The albumin and A /G ratio was decresed significantly in mice exposed to carbon tetrachloride($P{\leq}0.01$) 3) All of the activity of LDH, AST, ALT and ALP in mice serum exposed to carbon tetra chloride inclosed significantly activity of LDH ($P{\leq}0.05$), inclosed significantly activity of AST($P{\leq}0.05, \;p {\leq}0.01$), inclosed significantly activityof ALT 3nd ALP($P {\leq}0.05,\;p {\leq}0.01$). 4) The amount of cholesterol and triacylglycerol, lipid metabolite products in serum was inclosed in case of cholesterol but did not change in case of triacylglycerol.

The root of Polygonum cuspidatum (Polygonaceae) has been used as treatments of hyperlipidemia, dermatitis, gonorrhea, favus athlete's foot, inflammation in traditional medicine. In order to examine anti-lipidperoxidation activity, hexane, EtOAc, BuOH and water fractions of its methanol extract were administered to carbon tetrachloride intoxicated rats. Ethylacetate fraction exhibited antilipidperoxidative effect on liver lipid homogenate and the radical scavenging effect on DPPH. Serum transaminase, AlP, triglyceride and total cholesterol contents significantly decreased by administrations of ethylacetate fraction.

A nuclear, biological, chemical (NBC) canister was indigenously developed using active carbon impregnated with ammoniacal salts of copper (II), chromium (VI) and silver (I), and high efficiency particulate aerosol filter media. The NBC canister was evaluated against carbon tetra chloride ($CCl_4$) vapours, which were used as a simulant for persistent chemical warfare agents under dynamic conditions for testing breakthrough times of canisters of gas masks in the National Approval Test of Respirators. The effects of $CCl_4$ concentration, test flow rate, temperature, and relative humidity (RH) on the breakthrough time of the NBC canister against $CCl_4$ vapour were also studied. The impregnated carbon that filled the NBC canister was characterized for surface area and pore volume by $N_2$ adsorption-desorption isotherm at liquid nitrogen temperature. The study clearly indicated that the NBC canister provides adequate protection against $CCl_4$ vapours. The breakthrough time decreased with the increase of the $CCl_4$ concentration and flow rate. The variation in temperature and RH did not significantly affect the breakthrough behaviour of the NBC canister at high vapour concentration of $CCl_4$, whereas the breakthrough time of the NBC canister was reduced by an increase of RH at low $CCl_4$ vapour concentration.

Pitch-binded activated carbon fiber(ACF)/$TiO_2$ composite photocatalysts were prepared by Carbon Tetra Chloride (CTC) solvent mixing method with different mixing ratios of anatase to ACF. The result of the textural surface properties demonstrated that there is a slight increase in the Brunauer, Emmett and Teller (BET) surface area of composites with an increase of the amount of ACF. The surfaces structure morphologies of the composites were observed using an Scanning Electron Microscope (SEM). In the XRD patterns for all ACF/$TiO_2$ composites, the diffraction peaks showed the formation of anatase crystallites. The EDX spectra showed the presence of C, O and Si with strong Ti peaks. Most of these samples were richer in carbon and major Ti metal than any other elements. From the photo-decomposition results, the excellent activity of the ACF/$TiO_2$ composites between c/$c_0$ for methylene blue and UV irradiation time could be attributed to both the effects of the photocatalysis of the supported $TiO_2$ and adsorptivity of activated carbon fiber and another carbon derived from pitch.

The delta-endotoxin from B. thuringiensis subsp. damstadienszs 73E10-2 was resistant to high concentration of salt (4M NaBr), organic solvents (50% acetone), denaturants (4 M urea), and neutral detergents (10% triton X-100). In contrast, the toxin was inactivated by treating with charged detergents as well as guanidine hydrochloride or carbon tetra-chloride. The delta-endotoxin is not a sulfhydryl activated toxin, but modification of the lysine side chains eliminated toxicity against mosquito larvae.

The present study was done with two aims. First, to evaluate the radiographic measurements of liver volumes in normal and hepatomegaly dogs induced by carbon tetrachloride. Second, to investigate quantitative tissue echo pattern by ultrasonography. Gray level histogram of the normal liver and the kidney were estimated with carbon tetra-chloride intoxication. In normal, r-square for liver volume to body weight was 0.93372, and this showed direct linear regression. Gray level histograms of the normal liver and the kidney were $19.150{\pm}2.490$(mean${\pm}$SD) and $13.175{\pm}2.686$(mean${\pm}$SD) respectively(p < 0.01). Liver parenchymal echogenicity was more hyperechogenic than kidney cortex echogenicity. Liver/Kidney ratio was $1.504{\pm}0.313$ and it can be used relative comparison of liver and kidney parenchymal echogenicity. In carbon-tetrachloride($CCl_4$) intoxication, changes of liver volume appeared to increase up to 24 hours after administration (p < 0.05), and decreased gradually to normal level after 2~5 days. Gray level histogram of liver parenchyma decreased up to 24hours (p < 0.01) after intoxication and then gradually increased to normal level. But that of kidney cortex had no significant change. Liver/Kidney ratio also decreased by 2 days(p < 0.01) and then gradually increased to normal level. On histopathologic features of hepatic tissues in carbon tetrachloride intoxication, both coagulative necrosis of hepatic cell and hemorrhage of centrilobular & midzonal area were identified. Conclusively, plain radiography is a useful diagnostic method for evaluating liver volume in mild hepatomegaly. Especially, it is considered that an adequate numerical processing of the liver length, depth and thoracic width and depth measurement would be helpful. Using gray level histogram, ultrasonographic evaluation was useful objective methods in early diagnosis of diffuse hepatic disease.

To utilize waste of squid effectively, antioxidant properities of squid viscera were elucidated. Major fatty acids of total lipid, neutral lipid and phospholipid were $C_{16:0},\;C_{18:1}\;and\;C_{20:5},\;C_{22:6}$ and consisted $63{\sim}71\%$ of total fatty acids. Total lipid did not show significant antioxidant activity when added to the fish oil at the concentration below $5.0\%$, Antioxidant activity of hexane extract was lower than total lipid or tetra carbon chloride-methanol($CCl_4-MeOH$) extract. Extracts with $CCl_4-MeOH$ exerted higher antioxidant activity as the methanol ratio was increased, suggesting that polar lipid plays and important role.

Polymerization of carboxylated styrene-butadiene latex takes longer time than that of acrylic emulsion due to delocalization of radical in butadiene unit having conjugated double bond. A latex stability is the most important properties owing to use intact without separating polymer from base latex. For reducing polymerization time without decreasing any properties of latex, carbon tetra-chloride which has been used as the most popular chain transfer agent was replaced to combination of tert-dodecylmercaptane and ${\alpha}$-methylstyrene dimer. The replacement yielded reducement or 2 hr in polymerization time. In the increment step, charge amount of acrylic acid was limited to 0.3 part to restrain viscosity enhancement. Just after initial step, addition of 0.1 part acrylamide prevent polymer chain from diffusing between two region followed by giving hardness and final good adhesive force to latex particles.
