  • This study was performed to investigate the effects of cell-wall broken spores of Ganoderma lucidum on the lipid accumulation and body weight reduction in C57BL/6J mice. Six-week-old C57BL/6J mice were randomly divided into 5 groups and assigned to one of these groups; normal chew diet(Nor) group, high-fat diet(HFD) group, HFD plus spores of Ganoderma lucidum 800 mg/kg/day (HFD + GS/B) group, HFD plus cell-wall broken spores of Ganoderma lucidum 400 mg/kg/day (HFD + BGS/A) group and finally HFD plus cell-wall broken spores of Ganoderma lucidum 800mg/kg/day (HFD + BGS/B). The experimental groups which were treated oral co-administration with cell-wall broken(or original) spores of Ganoderma lucidum and HFD significantly attenuated accumulative body weight gain, compared with HFD group. Administration of these experimental materials also resulted in significant reduction not only the serum levels of total cholesterol, homocysteine but also the lipid accumulation in liver tissue. But in the almost of results the cell-wall broken spores of Ganoderma lucidum were evaluated superior than the original one. These results indicate that cell-wall broken spores of Ganoderma lucidum may inhibit the lipid accumulation in blood as well as liver tissue. Therefore it may be a valuable candidate for the therapy preventing obese induced hyperlipidemic symptoms.

  • As a novel method to improve strength properties of recycled test liner, Condebelt press drying system was introduced and adopted into Korea. New press drying treatment could enhance the surface and strength properties in accordance with the increase of sheet density. However, Condebelt drying can not increase the density of repeatedly recycled test liner as much as that of virgin UKP and at the same density condition, the strength of Condebelt press dried UKP is greater than that of press dried test liner. In order to increase the strength of test liner, two attempts were tried in this study. First, addition of polyelectrolytes, dry strength agent was investigated with a view to promote the fiber bonding potential of reclaimed corrugated container pulp. Second, blending effect of fines were analyzed in an aims of increasing density and strength of test liner. The results were as follows; Even in the case of test liner densified by Condebelt press dryer, addition of amphoteric PAM as a dry strength agent was effective in increasing strength properties and so the effect of dry strength agent on improving bonding potential of recycled OCC fiber could be confirmed. As an appropriate addition level of amphoteric PAM, below 1% based on dry pulp weight was suggested. Different from virgin UKP, density of recycled test liner can be increased by the blending of OCC fines and strength properties also can be improved. However, excessive blending of OCC fines could result in decreasing of density and serious weakening of test liner. The best blending ration of fines in test liner can be determined as about 30%. Taking into account the fines content in general OCC pulp as 50%, excessive 20% of fines were supposed to be fractionated and removed in order to achieve the best strength of Condebelt press dried test liner.

  • This study was conducted to investigate the growth patterns of Maackia amurensis growing in natural forest of Mt. Joongwang, Pyongchang-gun, Kangwon-Do, Korea. The 28 sample plots(30m$\times$30m) wee established to examine the vegetation and environmental conditions for M. amurensis forest. Stem analysis was performed on two sample trees of M. amurensis for each of the 5 plots situated at intervals of one hundred meters by altitude. The results obtained were as follows: ⑴ Height growth of M. amurensis increased with increasing age until 10 years, and then decreased thereafter, especially at altitude of 1,020m. ⑵ M. amurensis showed rapid early growth of height and volume, indicating high biomass production under favorable environment. This growth pattern is typical of pioneer species such as Cornus controversa and Betula costata. ⑶ The rotation age of natural M. amuensis forest was estimated at above 50 years, and especially at about 60 years in 840m above the sea level. ⑷ Growth of M. amurensis increased greatly at about 40 years when released from severe competitions.

  • Exploitation of the papermaking technology to reduce the strength loss that accompanies when using recycled papers as raw materials for papermaking is one of the most important issues imposed upon today's paper industry. Multi-layer sheet forming technology has been suggested as a way that provides some answers to this issue. In this study strength properties of single- and two-layer handsheets formed with recycled fiber and unbleached softwood kraft pulp have been examined to quantify the benefits when using two-layer sheet forming technology rather than a conventional single layer sheet forming precess. Single- and two-layer handsheets were made from 50% of OCC and 50% of Sw-UKP and their strength properties were evaluated. Also the strength properties made from Sw-UKP and OCC sheets were determined. A multihead, which can be attached on the top of hand- sheet former, was used to form two-layer sheets. Maximum strength properties could be obtained in the freeness range of 500∼300mL CSF for Sw-UKP Most of the strength properties was reduced by 30∼35% when 50% OCC was blended with UKP. Decrease of strength properties, however, could be reduced by employing a two-layer sheet forming method. Creator strengths could be obtained when UKP was positioned at the top layer of two layered sheets indicating greater UKP fines retention due to the filtration effect of the OCC layer formed prior to UKP layer contributed the strength improvement. Two-layer sheet showed lower Scott internal bond strength than single layer sheet. By incorporating some of UKP fibers into OCC layer this reduction could be reduced.

  • This study was designed to compare by the body composition in 4 groups of Sprague-Dawley rats during starvation previously fed with standard, high Carbohydrate, high protein or high fat diet. A) In different internal organs and skeletal muscles, the weights were differently reduced during starvation. Especially the weight reduction of liver was the highest level at $50{\sim}70%$, and adrenal glands did not change significantly. After death due to starvation, body weight decreased morethan 40% comparing to the initial body weight and epididmal fat pads disap peared completely. B) In rats starved to death, the changes of body composition (%) were following; lipid content was markedly reduced, while protein was similar to that of zero day starvation, ash increased slightly and water content increased. C) Five days starvation did not change body composition and body weight significantly. D) Effects of succeeding starvation after feeding 4 different diets were not significant, and it seemed that 4 different diets did not affect life span due to starvation.

  • This study investigated the effects of soyoligosaccharide consumption on lipid profile of plasma, liver and feces and immune responses in Sprague-Dawley male rats. Sixty male Sprague-Dawley rats 4-wk-old were provided the soyo-ligosaccharide containing diets for 4 weeks (0, 100 g/kg diet); each of these diets was supplemented with either 70 or 200 g fat/kg diet, giving a total of 4 experimental groups. The effect of weight reduction was most significantly observed in the group fed low fat and soyoligosacchairde diet. The plasma total lipid and cholesterol contents were not changed by either fat proportion or soyoligosaccharide supplementation in the diets. Also the plasma triglyceride lowering effect by soyoligosaccharide was not observed in rats fed either low fat or high fat diet. However, the significant decrease in TG contents was found with rats fed high fat diets compared to the control/no soyoligosaccharide diet. Elevation of plasma LDL-cholesterol and reduction of HDL-cholesterol by feeding high fat diet was not altered by supplementing soyoligosaccharide. This was also applied to the liver lipid profiles. The significant increases in liver total lipid, trigly-cerides and cholesterol by high fat diet was not abolished by feeding soyoligosaccharide. However, the desirable effects of feeding soyoligosaccharide were found with total lipid and cholesterol excretion through feces in rats fed high fat diets. Immune organ weights and spleen cell proliferations did not affected by experimental diets. These results de-monstrated that soyoligosaccharide intakes increased the lipid output via feces, especially in rats fed the high fat diet, but more researches are needed on immune responses.

  • In the previous experiment, it was found that OCC pre-treatment with Hobart mixer at 20-25% consistency for 3 hrs or more followed by the application of the equal refining time, caused the increase of tensile strength, burst strength, compressive strength and tear resistance, compared to the no pre-treated. Four completely different fibers, which were Hw-BKP, Sw-BKP, White ledger, and OCC were selected for this experiment to investigate the effect of mechanical pre-treatment process on different fibers. From the experiment, it was found that the mechanical pre-treatment did not decrease fiber length at all, but decreased freeness, com-pared to the no pre-treated, when the same refining time was applied. WRVs of the pre-treated fibers were higher than the no pre-treated at the same freeness level. It was speculated that the mechanical pre-treatment induced only hydrophilic nature of fibers without damaging fiber length by delaminating fiber walls. The fiber surface area and the physical strength differences of handsheets will be discussed in the next publication.

  • This study is a continuation of the previous experimental analysis and is mostly focused on handsheet strength properties. Four completely different fibers, which were Hw-BKP, SW-BKP, White ledger, and OCC, were selected to investigate the effect of mechanical pre-treatment by Hobart mixer on handsheet strehgth properties. After equal time mechanical pre-treatment, the fibers were refined with laboratory valley beater for 10, 20 and 30 minutes, and handsheets were prepared from the fibers for physical strength comparison. Handsheets from SW-BKP and OCC showed 5-30% increase of breaking length, burst index, tear index, and compression index while handsheets from HW-BKP and White ledger no increase except tear index. In Hobart mixer pre-treatment, HW-BKP and White ledger fibers were easily attached to the wall of the mixer bowl and mechanical action was not effectively applied. The fiber length of Hw-BKP and White ledger were 0.837 mm and 1.591 mm, respectively, while SW-BKP and OCC were 2.744 mm and 2.033 mm, respectively, in weight weighted length. The effective mechanical pre-treatment seems to be related to the fiber length. Tear indexes of the pre-treated furnish were much higher than no pre-treatment at the same breaking length level.
