Conjugated linoleic acid(CLA) is a naturally occuring group of derivatives of linoleic acid found in beef and dairy products. CLA has reported to reduce body fat. This study was designed to observe the effect of CLA supplementation on fat accumulation and degradation in male Sprague Dawley rats. Seventy two rats, weighing 150-180g, were divided into 2 groups according to the types of dietary fat(beef tallow or fish oil) and then each group was divided into 2 groups depending on CLA supplementation, i.e., BT, BT-CLA, FO, FO-CLA. All rats were fed experimental diet containing total fat at 12%(w/w) including CLA at 1% for 30 weeks. At 30 weeks, rats were sacrificed to measure TG, free fatty acid level in plasma, TG, lipogenic enzymes in lever and fat cell size, LPL and HSL activities in epididymal fat fad. Fish oil supplemented with CLA diet showed significant reduction in the food efficiency and weight in 30 weeks-fed rats. CLA supplement did not effect on plasma TG, hepatic TG levels and lipogenic enzymes activities in rats, but, fish oil significantly reduced, The LPL and HSL activities did not affected by CLA supplement and n-3 fatty acid rich fish oil. In conclusion, the results suggest that CLA supplement was not a proper way to reduce the fat accumulation in Sprague Dawley rats. Fish oil supplemented with CLA might better way to reduce the body fatness than fish oil itself. Therefore, It is recommended that further study be performed related to physiological and biochemical effects of CLA supplementation and n-3 fatty acid in rats for the reduction of body fatness.(Korean J Nutrition 34(4) : 367∼374, 2001)

Objective: The purpose of this study was to determine the utility of preoperative CT in predicting early recurrence of hepatocellular carcinoma after partial hepatic resection. Materials and Methods: Preoperative three-phase helical CT scans in 53 patients with hepatocellular carcinoma were retrospectively reviewed by two radiologists. In 27 patients (group I), HCC had recurred within six months, while 26 (group II) had remained disease free for at least two years. In each group, preoperative CT findings were evaluated in each group for the tumor size and number, the presence or absence of capsule, distinctness of tumor margin, perinodular extension, and the presence or absence of portal vein thrombosis. Results: In group I, a tumor capsule of tumor was seen in five of 27 patients (19%), and in group II, in 16 of 26 (62%) (p = .001). The tumor margin was distinct in eight patients (30%) in group I and in 20 (77%) in group II (p = .001). Multiple tumors, perinodular extension, and portal vein thrombosis were more frequently seen in group I but the differences were not statistically significant (p > .05). Tumor size was similar in each group (p > .05). Conclusion: Preoperative CT findings that may help predict the early recurrence of hepatocellular carcinoma after surgical resection are an absence of capsule of tumors and an indistinct margin. Reference to these findings during preoperative CT can guide clinicians in their choice of treatment.

A recent successful prospective randomized control study comparing open distal pancreatectomy with laparoscopic distal pancreatectomy (LDP) has shown that LDP is a safe and effective surgical modality in treating left-sided pancreatic pathological conditions requiring surgical extirpation. With the accumulating surgical experiences and improved surgical techniques, we recently reported several cases of successful LDP in advanced pancreatic cancer following neoadjuvant chemotherapy. Herein, we report a case of LDP with celiac axis resection (LDP-CAR) in locally advanced pancreatic cancer (LAPC) following neoadjuvant chemotherapy. A 58-yearold female with LAPC was referred to our institution. Computed tomography (CT) findings revealed a 24-mm mass in the pancreatic body that showed celiac artery (CA), common hepatic artery abutment. There was no abutment with superior mesenteric artery, superior mesenteric vein, and portal vein. From these findings, Neoadjuvant chemotherapy (FORFIRINOX) was performed biweekly. After 8 cycles of chemotherapy, the tumor size was slightly decreased (24 mm to 16 mm), but still abutting to CA. After 14 cycles of chemotherapy, CT revealed the same tumor size (16 mm) still abutting to CA. LDP-CAR was performed. Intraoperative ultrasonography gastric perfusion and hepatic perfusion were confirmed using indocyanine green. The patient recovered without complications and was discharged from the hospital nine days after the surgery.

Background: The size of a hepatic neoplasm is critical for staging, prognosis and selection of appropriate treatment. Our study aimed to compare the radiological size of solid hepatocellular carcinoma (HCC) masses on magnetic resonance imaging (MRI) with the pathological size in a Chinese population, and to elucidate discrepancies. Materials and Methods: A total of 178 consecutive patients diagnosed with HCC who underwent curative hepatic resection after enhanced MRI between July 2010 and October 2013 were retrospectively identified and analyzed. Pathological data of the whole removed tumors wereassessed and differences between radiological and pathological tumor size were identified. All patients were restaged using a modified Tumor-Node-Metastasis (TNM) staging system postoperatively according to the maximum diameter alteration. The lesions were classified as hypo-staged, iso-staged or hyper-staged for qualitative assessment. In the quantitative analysis, the relative pre and postoperative tumor size contrast ratio ($%{\Delta}size$) was also computed according to size intervals. In addition, the relationship between radiological and pathological tumor diameter variation and histologic grade was analyzed. Results: Pathological examination showed 85 (47.8%) patients were overestimated, 82 (46.1%) patients underestimated, while accurate measurement by MRI was found in 11 (6.2%) patients. Among the total subjects, 14 (7.9%) patients were hypo-staged and 15 (8.4%) were hyper-staged post-operatively. Accuracy of MRI for calculation and characterized staging was related to the lesion size, ranging from 83.1% to 87.4% (<2cm to ${\geq}5cm$, p=0.328) and from 62.5% to 89.1% (cT1 to cT4, p=0.006), respectively. Overall, MRI misjudged pathological size by 6.0 mm (p=0.588 ), and the greatest difference was observed in tumors <2cm (3.6 mm, $%{\Delta}size=16.9%$, p=0.028). No statistically significant difference was observed for moderately differentiated HCC (5.5mm, p=0.781). However, for well differentiated and poorly differentiated cases, radiographic tumor maximum diameter was significantly larger than the pathological maximum diameter by 3.15 mm and underestimated by 4.51 mm, respectively (p=0.034 and 0.020). Conclusions: A preoperative HCC tumor size measurement using MRI can provide relatively acceptable accuracy but may give rise to discrepancy in tumors in a certain size range or histologic grade. In pathological well differentiated subjects, the pathological tumor size was significantly overestimated, but underestimated in poorly differentiated HCC. The difference between radiological and pathological tumor size was greatest for tumors <2 cm. For some HCC patients, the size difference may have implications for the decision of resection, transplantation, ablation, or arterially directed therapy, and should be considered in staging or selecting the appropriate treatment tactics.

Haw (Crataegus pinnatifida Bunge) has been used in traditional medicine for treating various ailments such as obesity and digestive trouble in Far East countries, including Korea. The present study was carried out to investigate the effects of feral haw on hepatic functional enzymes in dyslipidemic rats. Four groups of male rats (Sprague Dawley strain) were fed different diets for 5 weeks: NND (normal-nondyslipidemic diet) group, NNDH (normal-nondyslipidemic diet + haw extract) group, CDD (control-dyslipidemic diet) group and DDH (dyslipidemic diet + haw extract) group. ALP (alkaline phosphatase), LDH (lactate dehydrogenase), AST (aspartate aminotransferase) and ALT (alanine aminotransferase) activities were significantly higher in the CDD group than the NND group. However, haw extract supplement significantly reduced hepatic functional enzyme activities compared to the CDD group. Lipid deposition of the DDH group decreased compared to the CDD group. The size of adipose tissue decreased significantly in the DDH group compared to the CDD group. These results suggest that feral haw could be used as a food resource and functional food material.

We investigated the effects of gambigyeongsinhwan(GGH)(4) on body weight and non-alcoholic fatty liver disease(NAFLD) examined whether blood total cholesterol, LDL-cholesterol, free fatty acid and triglyceride levels and hepatic lipid accumulation are inhibited by it in high fat diet-fed obese male mice. 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, GGH(4)-1, GGH(4)-2 and GGH(4)-3. After mice were treated with GGH(4) for 8 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma ALT, leptin and lipid levels. We also did histological analysis for liver and fat on the mice. Compared with controls, GGH(4)-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in GGH(4)-2. Compared with controls, GGH(4)-treated mice had lower feeding efficiency ratio and blood leptin level, the magnitudes of which was prominent in GGH(4)-2. Compared with controls, GGH(4)-treated mice had lower blood plasma total cholesterol, LDL-cholesterol, free fatty acid and triglyceride levels. Compared with controls, GGH(4)-2 treated mice had lower blood plasma ALT concentration. Consistent with their effects on body weight gain, the size of adipocytes were significantly decreased by GGH(4), whereas the adipocyte number per unit area was significantly increased, suggesting that GGH(4) decreased the number of large adipocytes. Hepatic lipid accumulation was decreased by GGH(4). In conclusion, these results suggest that GGH(4) exhibits anti-obesity effects through the modulation of feeding efficiency ratio and plasma obesity parameters. Moreover, it seems that GGH(4) also contributes to improve NAFLD through the regulation of plasma ALT and hepatic triglyceride accumulation.

This study examined the effects of a soybean sprouts mixture containing 1.5% Hovenia dulcis Thunb. fruit concentrate (SHM) on relieving hangovers and improving liver function in chronically alcohol-treated rats. The ampelopsin and L-asparagine contents in the SHM were 10.52, 35.19 ppm. When chronic alcohol-induced rats were treated with SHM, the body weight increased and the liver weight decreased. The serum alcohol and acetaldehyde concentrations were lowest in the SHM group, and the hepatic ADH and ALDH activities were highest in the SHM group. Chronic alcohol induction increased the activity of liver function indicator enzymes such as ALT, AST, and GGT, but the activity was decreased significantly with the SHM treatment. The triglyceride content in hepatic and serum blood samples was lowest in the SHM group. The serum total cholesterol and LDL cholesterol contents decreased in the SHM group, and the HDL cholesterol content increased. The color of the hepatic observed morphologically in the SHM group was reddish brown, and the size and number of lipid droplets in the hepatic observed pathologically decreased. The hepatic and serum lipid peroxidation content of the SHM group decreased. The hepatic and serum GSH content increased in the SHM group. Therefore, SHM can be a functional food that can help hangovers and improve liver function.

Categorizing prognostic factors is very useful for a disease diagnosis, determination of treatment and study eligibility criteria. Methods often used to categorize factors are to select a cutpoint by biological theory, by graphical examination, by the minimum p-value approach. The last method involves multiple testing, and several methods for adjusting p-values have been developed. This study determines the cutpoint of tumor size to separate patients of high risk of relapse after hepatic resection of hepatocellular carcinoma.

This experimental study was designed to investigate the effects of Seunggijoui-tang on the weight of obese rats induced by high fat diet. A series of experiments have been conducted in order to measure the effects of above the body weight, serum and fat cell. The measurements have been performed on; (1) the increasing amount of body weight; (2) the quantity of total cholesterol, triglyceride, free fatty acid, total lipid, phospholipid, HDL-cholesterol and LDL-cholesterol in serum; (3) the size of the epididymal fat cell and the fat drops area in hepatic lobule. In the SG I (Group fed high fat diet and administered 42.5mg/100g extract of Seunggijoui-tang during 8 weeks), the weight decreased significantly throughout the whole research period. In the SG I & SG II (Group fed high fat diet and administered 85mg/100g extract of Seunggijoui-tang during 8 weeks), the serum total cholesterol, triglyceride, total lipid, phospholipid, LDL-cholesterol decreased significantly in comparison with control group. In the SG I, the serum free fatty acid decreased significantly in comparison with control group. In the SG I & SG II, the serum HDL-cholesterol decreased in comparison with control group, but this result showed no efficacy. In the SG I, the epididymal fat cell decreased significantly in comparison with control group. In the SG II, the fat drops area in hepatic lobule of rats decreased significantly in comparison with control group. Based on the above result, it is assumed that the clinical application of Seunggijoui-tang can help the treatment of obesity.
