  • Ca salt of soybean oil (PSO) and that of mustard oil plus mahua oil (PMOMO) (50:50) were prepared using double decomposition method, and further tested for their fatty acid composition and degree of saponification. Furthermore, the different levels of protected fat of PSO and PMOMO were evaluated in wheat straw based total mixed ration (TMR) in vitro. Results indicated that capric, lauric, myristic, palmitic, steric, oleic, linoleic, leinolenic acids were traces, traces, traces, 10.00, 2.00, 25.00, 58.50, 5.0% in PSO while the corresponding values in PMOMO were 1.08, 0.28, 0.45, 16.9, 12.95, 44.38, 17.46 and 6.50%, respectively. The degree of saponification of both protected fat supplements was more than 80%. Six treatment combinations were tested I.e., blank without feed and fat supplement (T1); control diet with out fat supplement (T2); control diet plus bypass fat supplement (PSO) so that diet contain 5% fat (T3); control diet plus bypass fat supplement (PSO) so that diet contain 7.5% fat (T4); two more diets viz. T5 and T6 were formulated using bypass fat supplement from PMOMO containing 5 and 7.5% fat respectively. TMR was prepared using 50% concentrate mixture and 50% wheat straw. Result indicated that TVFA, $NH_3-N$,TCA-N, total-N and total gas production were increased in treatment diets at 7.5% level of supplementation, however, fermentation pattern remain similar at 5.0% level of supplementation with respect to control diet. Nevertheless, IVDMD and IVOMD values remained unchanged, rather non-significant at both fat levels and with the both fat sources. On the basis of results it was concluded that Ca-salt of Soybean oil or Mustard plus Mahua oil did not show any negative effect either on digestibility or on microbial protein synthesis in rumen, hence the dietary fat upto 7.5% level in total mixed ration based on wheat straw, could be safely used without any adverse effect on rumen fermentation.

  • This experiment investigated whether yogurt containing fermented pepper juice (FPJY) affects cholesterol level in high fat and high cholesterol diet (HFCD) fed rat. Twenty five Sprague-Dawley male rats of 7 wk were divided into 5 groups, and fed following diets for 9 wk; CON (control diet), HFCD (HFCD), PY (HFCD supplemented with 2% of plain yogurt), LFY (HFCD supplemented with 2% of FPJY), and HFY (HFCD supplemented with 5% of FPJY). In the LFY group, hepatic total lipid level decreased significantly compared to the HFCD group (p<0.05). Serum HDL cholesterol level tended to increase and hepatic total cholesterol level decreased and were comparable to the CON group (p>0.05). In HFY group, body weight and hepatic total lipid level significantly decreased over the HFCD group (p<0.05). Serum and hepatic total cholesterol level, kidney, and body fat weights decreased, and were compared to the CON group (p>0.05). Liver weight decreased as FPJY content was increased. Results suggested FPJY would inhibit organ hypertrophy and accumulation of body fat, hepatic lipid, and cholesterol in HFCD fed rat.

  • This study was performed to compare the differences between total fat area, subcutaneous fat area and visceral fat area according to L1-S1 inter vertebral disc level in asymptomatic Korean patients with non-contrast abdominal CT scan. The location of the maximum fat ratio of the total fat area is the total fat area measured in male L2-3, L3-4, L4-5, female L4-5, and L5-S1. The location showing the maximum fat ratio of the subcutaneous fat area is the subcutaneous fat area measured in male L4-5, and the woman is the subcutaneous fat area measured in L4-5 and L5-S1. The location of the maximum fat ratio of visceral fat area was the visceral fat area measured in L1-2 and L2-3 males, and there was no difference in visceral fat area according to the measured position in females. Although abdominal fat measurement is common at the L4-5 inter vertebral disc level, fat distribution varies widely depending on nationality, race, and gender. Therefore, it is necessary to analyze through the research data which location to choose according to the research purpose, and to mention why the location is appropriate.

  • This study was conducted to investigate the effect of dietary soluble fiber administration and/or high fat diet on serum and brain neurohormonal profiles, adipose tissue mass and body weight gain in Sprague-Dawley rats. Four groups of rats were respectively fed 10% fat diet (C), 10% fat plus pectin diet (P), 20% fat diet (HFC) and 20% fat plus pectin diet (HFP) for 4 weeks. In HFP group, the food and energy intake, body weight gain, FER including fecal excretion were the smallest (p<0.05). Serum HDL-cholesterol, triglyceride and glucose level were also the lowest in HFP group (p<0.05). The weight of brain, epididymal fat pad and adrenal gland except liver didn't show any significant differences among groups. Interestingly serum norepinephrine concentration of HFP group tended to be higher, but dopamine concentration tended to be lower than those of HFC group. However serum catecholamine concentration didn't show any significant differences among all groups. Norepinephrine and epinephrine contents of right portion of midbrain of P and HFP groups were remarkably lower than those of the C group. These results suggested that soluble fiber pectin consumption might affect neurohormonal profiles in serum and brain according to dietary fat level.

  • The purpose of this study was to investigate the effect of Lycii fructus on the serum lipid in rats fed high fat diet. We compared the effects of L. fructus and L.fructus water extract both adminstered with high fat diets on rats that had previously been on high fat or standard diets. Two separate experiments were conducted for 6 weeks. respectively. In experiment I, 4 groups of rats were fed experimental diets consisting of either \circled1 6 weeks of a standard diet(control), \circled2 6 weeks of a high-fat diet(HHC), \circled3 3 weeks of a high-fat diet followed by 3 weeks of a high-fat diet containing L. fructus(HHL) or \circled4 6 weeks of a high-fat diet with L. fructus extract in place of water for the last 3 weeks (HHT). In the second set of experiments, a high-fat diet (SHC), high-fat diet containing L.fructus(SHL) or high-fat diet with L. fructus extract in place of water (SHT) were fed for 3 weeks after 3 weeks of standard diet feeding. Rats fed L. fructus diet consumed more diets than high-fat diets. THe results of experiment I showed significant decreases(p<0.05) in serum triglyceride(TB) and low density lipoprotein-cholesterol (LDL-C) levels with L. fructus feedings, but did not show andy changes in total cholesterol (TC) level. High density lipoprotein-cholesterol (HDL-C) level was increased significantly(p<0.05) with L. fructus feedings. Therefore, the ration of LDL-C to HDL-C(LDL-C/HDL-C) which is used as an atherosclerosis index was significantly (p<0.05) low, while the HDL-c/TC ration was significantly(p<0.05) high with L.fructus intake. However, no significant were found in serum cholesterols and TG levels in experimentII. The results of these experiments indicate that , regardless of the feeding from, L. fructus can be beneficial in lowering serum TG and LDL-C levels for habitual high-fat diet intakers. L.fructus also seems to be effective in elevating serum HDL-C level, theregy having beneficial effects on atherosclerosis by influencing the serum lipoprotein profile.

  • A Fat-Tree topology has multiple paths between any pair of hosts. The delay for the multiple paths with an equal number of hops depends mainly on the queuing delay. However, most of the existing load-balancing schemes do not sufficiently exploit the characteristics of Fat-Tree. In most schemes load-balancing is performed at a flow level. Packet-level load-balancing schemes usually require the availability of special transport layer protocols to address packet reordering. In this paper, we propose a new packet-level load-balancing scheme which can enhance network utilization while minimizing packet reordering in Fat-Trees. Simulation results show that the proposed scheme provides as high TCP throughput as a randomized flow-level Valiant load balancing scheme for a best case.

  • This study examined the effect of the pine needle sap administration on serum lipid composition and liver antioxidant defense system in rats fed with high fat diet. Forty eight male Sprague-Dawley rats were divided into six groups. three control groups were fed with 5% lipid diet and three high fat groups were fed with 30% lipid diet. Each group was administered with the following pine needle sap respectively : C-0.0, 1.ml water, C-0.5, 0.ml pine needle sap and 0.ml water C-1.0, 1.ml pine needle sap : H-0.0, 1.ml water, H-0.5, 0.ml pine needle sap and 0.ml water H-1.0, 1.0ml pinus needle sap. After 4 weeks of experimental periods the level of serum obtained and serum lipid was measured respectively. The results were as follows 1. Significant low level was observed for food intake, weight gain, FER in the experimental group administered with the pine needle sap. 2. No difference of the concentration of serum triglyceride was observed out the experimental group with 5% fat diet, however out of the experimental group with 30% fat diet it was low in (H-1.0) group where 1.0ml of the pine needle sap was administrated. 3. In the experimental group with 5% fat diet the concentration of serum total cholesterol and LDL cholesterol was low, especially the hypocholesteromic effect in serum administered by the pine needle sap was significantly high in group C-1.0 where 1.0ml of pine needle sap was administered. In the high fat group provided with 30% fat when the pine needle sap was administered there was a tendency that concentration of total cholesterol and LDL cholesterol decreased however there was no difference significantly. 4. Serum GOT activity was relatively high in high fat diet group. However, when 1$m\ell$ of pine needle sap was administered the activity was lower than that of the control group in H-1.0 group and the activity level was similar with that of the high fat diet group in c-1.0 group. There was no difference of serum GPT activitives followed by the administered of pine needle sap among the experimental group. 5. Liver TBARS levels were high in general in high fat diet group, however it showed no difference when the pine needle sap with different concentration level was administered. The results of this study indicate that the pine needle sap administration was effective in decreasing the food intake and weight gain of the experimental animals in the high fat diet and also effective in decreasing the levels of serum triglyceride, total cholesterol and LDL cholesterol and GOT activities. However it was not effective to change the level of TBARS and GSH -Px activities of liver. Thus, it was found that the pine needle sap administration was effective for the improvement of serum lipid composition condition of the experimental animals in the high fat diet group but it was not effective in the antioxidant defense system of liver.

  • This research was designed to study the effect of Korean dietary lipids on the lipid metabolism and the immune function in young rats . The three different lipid sources were compared lard, perilla oil and fish oil. Three different levels of lipid in the diet, 2%, 15% and 30%,on the weight basis, were included. After four weeks feeding, the rats were sacrified and blood sample was collected to analyze for the total lipid, TG and cholesterol contents in serum. The HDL fraction in serum was seperated by the electrophoresis of lipoproteins. The immune responses were measured by the blastogenesis of spleen lymphocyte stimulated by PHA and in serum were measured. The following results were obtained. Lower body weight gain was shown in 30% lipid diet fed group on the isocaloric basis. In concerning the different dietary lipid sources, there were significantly lower boyd weight gain in fish oil than in perilla seed oil and lard group in 30% lipid groups. Deposition of body fat expressed by epididymal fat pad in serum were significantly different among perilla seed oil, lard and fish oil groups. Perilla seed oil group showed lowest level of total lipid and TG in serum regardless of dietary fat level. The feeding perilla seed oil to rats was resulted in lower serum cholesterol levels than lard in all three levels of fats tested. The HDL fraction was elevated in perilla seed oil group at the high fat level. The stimulating responses of lymphycotes by PHA did not seem to be influenced by different dietary fat sources. However, conA mitogenic responses was significantly increased in perilla seed oil group. The lower level of perilla seed oil (2%, 15%) showed slightly higher responses of ConA, indicating that lower level of perilla seed oil might have stimulatory response on the immune response. The number of antibody forming cells of spleen against SRBC was increased in 30% fat level for all the three kind of fats. However, no effect has been found in plaque forming cell response by the differences in dietary fat sources. There were no significant differences in serum IgG and IgA levels in all dietary groups.

  • The study was designed to observe the effects of dietary intake of three different levels of polyunsaturated to saturated fatty acid (P/S) ratio on plasma HDL - cholesterol and triglyceride in plasma and tissues of adult rats. Rats were assigned into the three diet groups, composed of protein 24%, carbohydrate 46%, and fat 30% of total caloric intake. However, the P/S ratio of fat was adjusted by using beef tallow, corn oil and perilla oil to give 0.2, 1.1 and 6.0. All groups were fed ad libitum for 4 week. Plasma cholesterol level was decreased but net significantly with increasing P/S ratio of dietary fat, and showed significant negative correlation coefficient. Plasma TG level was also decreased with increasing PUFA level of dietary fat. However, the effect of P/S ratio (6.0) was not greater than that of P/S ratio (1.1) on plasma TG concentration. This implied that high level of PUFA was not required to change plasma TG level as much in the case of HDL-cholesterol. Plasma HDL-cholesterol was significantly increased only in the group of P/S ratio 6.0 which suggested that high level of dietary PUFA was required to increase HDL level. There was a decreasing trend in the levels of total cholesterol and TG per g liver with increasing P/S ratio of dietary fat. There was no effect in the levels of TG per g skeletal muscle by P/S ratio but the level of cholesterol per unit skeletal muscle was rather increased with increased P/S ratio.
