  • The influence of refeeding either protein, carbohydrate or fat on hepatic insulin-like growth factor-I (IGF-I) mRNA level in chicks which had been fasted for 2 days was examined. The hepatic IGF-I mRNA was measured by ribonuclease protection assay. Fasting reduced hepatic IGF-I mRNA levels to less than half of those in the fed control. When chicks were refed either a control, protein or carbohydrate diet, IGF-I mRNA levels significantly increased to those in the fed control until 2 hours of refeeding. Refeeding of fat did not alter hepatic IGF-I mRNA levels. The significant correlation between liver weight and hepatic IGF-I gene expression suggests that when chicks are refed after 2-d fasting, the acute increase in hepatic IGF-I gene expression brought about after refeeding may be partly regulated by the increase in liver protein metabolism.

  • Refeeding syndrome is a life-threatening but treatable condition occurring in any patients with starvation. Electrolyte imbalance, especially hypophosphatemia and fluid shift result in metabolic changes in various systems. The authors reported a case of refeeding syndrome associated with prolonged starvation due to delusion and hallucination in a 38-year-old schizophrenia patient. Hypophosphatemia, hypokalemia, edema and elevation of liver enzyme was occurred despite careful treatment. The symptoms were improved after consistent electrolyte supplement. Close observation and repetitive monitoring are important to prevent refeeding syndrome.

  • The influence of refeeding with either vitamin, mineral, fibre of water on protein synthesis and mRNA content in the liver and breast muscle of fasted chicks was investigated. At 15 d of age, chicks were fasted for 2 d and then refed either vitamin, mineral, fibre or water. The fractional synthesis rate (FSR) of protein was measured after 30 min of refeeding by using a large dose injection of L - 2, $6[^3H]$ phenylalanine. In the liver, FSR was reduced by fasting and tended to increase but not significantly by refeeding with vitamin or mineral. FSR was not affected by refeeding with fibre or water. There was no influence of fasting and refeeding on ribosomal capacity (the RNA : protein ratio) and ribosomal efficiency (total protein synthesised per total RNA). The absolute synthesis rate (ASR) of liver protein and hepatic mRNA content were reduced by fasting and unchanged by refeeding. In the muscle, FSR, ASR and mRNA content were significantly decreased by fasting and not recovered by refeeding with either vitamin, mineral, fibre or water. It concluded that vitamin, mineral, fibre and water have little capacity to stimulate liver and muscle protein synthesis reduced by fasting.

  • We investigated the effects of short-term food restriction and repeated fasting and refeeding on appetite regulating hormones and adiponectin activity in rats. To investigate the acute and chronic effects of food restriction in vivo, Sprague-Dawley rats were divided into a control group (CON), a 1 day fasting group, a 2 days fasting gruop, a 3 days fasting gruop, a fasting and refeeding for 1 week gruoup and a fasting and refeeding for 2 weeks group. Blood glucose, triglyceride and total cholesterol decreased in all fasting groups compared to those in the CON group. Free fatty acid of all fasting groups was higher than those in the CON, and were lowest in the three cycle fasting and refeeding group. Blood insulin following short-term food restriction was lower than that in the CON. blood ghrelin increased significantly (p < 0.01) following the short-term food restriction, However, blood ghrelin in the repeated fasting and refeeding groups decreased significantly decreased (p < 0.01) compared to that in the CON and short-term food restriction group. In contrast, blood leptin decreased significantly (p < 0.01) in the short term food restriction group and the three cycle of fasting and refeeding group but increased in the six cycle of fasting and refeeding group. No significant differences in adiponectin contents were observed in the short-term food restriction group. But, adiponectin increased significantly (p < 0.01) following the fasting and refeeding cycles. Blood adiponectin and blood leptin levels were showed positively correlated ($r^2$ = 0.469) when all samples were analysed together.

  • Objectives : The purpose of this study was to investigate the influence of modified fasting therapy using fermented herbal medicine on the changes of body compositions. Methods : This study was carried out on 11 patients who carried out modified fasting therapy using fermented herbal medicine. They went through reducing food intakes period(7 days), fasting period(10~14 days) and refeeding period(10~14 days). Body compositions(weight, BMI(body mass index), skeletal muscle mass, body fat mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were measured at each state. And then the data was analyzed. Results : 1. The weight and BMI decreased during the reducing food intakes period and the fasting period, and increased during the refeeding period. But the weight and BMI decreased during the fasting therapy period, as a whole. 2. The skeletal muscle mass decreased during the fasting period and increased during the refeeding period. As the final outcome, for the whole fasting therapy period, decrease of skeletal muscle mass didn't show significance. The body fat mass and percent body fat decreased during the reducing food intakes period, the fasting period and the refeeding period. 3. The basal metabolic rate decreased during the fasting period and increased during the refeeding period. As the final outcome, for the whole fasting therapy period, decrease of basal metabolic rate didn't show significance. 4. The waist-hip ratio decreased during the fasting period and the refeeding period. The visceral fat area decreased during the fasting period and refeeding period. Conclusions : Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions. This results are expected to compensate the defects of existing fasting therapy.

  • The purpose of this study was to evaluate the effects of repeated fasting and refeeding on lipid metabolism. Thirty male ICR mice, aged 6 weeks, were fed an AIN-93 control diet during the experimental period. The mice were divided into 5 groups: Non fasting group (ad libitum-fed, NF), fasting for 3 days (F), fasting for 3 days and then refeeding for 4 days repeated once (FRF1), fasting for 3 days and then refeeding for 4 days repeated twice (FRF2), and fasting for 3 days and then refeeding for 4 days repeated three times (FRF3). Rates of body weight gain, epididymal fat weight, and serum TG were significantly decreased in the F, FRF1, FRF2, and FRF3 groups, compared to the NF group. LDL-cholesterol was significantly higher in the FRF3 group than the NF and F groups, but HDL-cholesterol and HDL/TC were significantly lower in the FRF3 group than in the NF and F groups. Serum total carnitine was significantly lower in the FRF1, FRF2, FRF3 groups than the NF and F groups. However, rates of serum and hepatic acyl-carnitine concentration were significantly lower in FRF1, FRF2, and FRF3 than in NF and F. Repeated tasting-refeeding resulted in visible reductions of body weight and fat mass, but it caused ill-effects with lipid and carnitine metabolism in the body.

  • The gene expression of amylase, trypsin, and lipase in the digestive organs of the two-spotted cricket (Gryllus bimaculatus) was tested to understand how it overcomes starvation. Amylase gene expression in the foregut was reduced by digesting no food until starvation-3 days. Although that expression persisted to starvation-6 days, it returned to normal at refeeding-2 days. The expression of trypsin peaked at around 8 times as starvation started and at around 4 times at starvation-3 days. After refeeding, trypsin expression rose up to 14 times and then fell back to normal as feeding continued. Lipase gene expression remained elevated at 1.5-2 times when starvation started and returned to normal at refeeding-2 days. In the midgut, amylase expression decreased until starvation-3 days, increasing to about 2 times at starvation-6 days; it did not rise again by refeeding. Trypsin was constantly expressed regardless of starvation and refeeding, while lipase expression was reduced by 0.6-0.7 times by starvation and refeeding. Amylase gene expression in the hindgut was 0.2-0.3 times lower than starvation-6 days, and it increased by 0.5 times on refeeding-1 day and more than 1.5 times on refeeding-3 days. The gene expression of trypsin was almost identical to amylase.

  • We investigated compensatory growth of Nile Tilapia Oreochromis niloticus in structural size and live weight in response to different deprivation periods and refeeding. Four treatments were assigned randomly to fish in 12 glass tanks, with each treatment performed in triplicate. The control group was fed to satiation three times a day throughout the experiment. The other three treatment groups were starved for 1 week (S1), 2 weeks (S2), or 4 weeks (S4) and then fed until the end of the experiment. After the experiment, no significant differences were observed among S1, S2, and the control group in average weight or length, whereas the weight and length of S4 were significantly reduced. Relative condition factors of the three starved groups decreased significantly until the end of the restricted period but recovered rapidly after refeeding. The specific growth rate in weight ($SGR_W$) of the three restricted groups recovered quickly upon refeeding and were significantly higher than the control group, but these differences disappeared gradually until the end of the experiment. No significant difference in specific growth rate in length ($SGR_L$) was noted between the control group and the three restricted groups after refeeding. All three groups showed hyperphagia for a short period upon refeeding, and no statistical differences were observed in feeding efficiency among the four groups.

  • We report a rare case of gastric perforation in a 13-year-old boy with anorexia nervosa. He was admitted to our hospital with the chief complaint of body weight loss. He had lower abdominal pain after 2 days. An abdominal CT revealed diffuse peritonitis. At laparotomy, the stomach was dilated and perforated. Postoperatively, the patient suffered from malnutrition. We monitored electrolytes, minerals, and fluids closely before and during the initiation of feedings to prevent morbidity and mortality associated with refeeding syndrome. We present an extremely rare complication that relates to this phenomenon, describing an acute gastric dilatation that led to gastric necrosis and perforation through an unusual mechanism in an extremely anorectic teenager during hospitalization for refeeding.

  • The current study was undertaken to determine the prolinged effects of fasting-refecding on the lipoprotein lipase (LPL) activity and lipogenesis of adipose tissus in male Sprague-Dawley rals and to investigate the effects of various degrecs of food restriction during refeeding on the LPL activity and lipogenesis. The control group (n=5) was fed ad libitum and killed in the fed state at the beginning of the experiment. All rats except conteol group were fasted for 2 days (n=50). Five rats were killed at the end of fasting and others (n=45) were refed either ad libitum (ad libitum group) or mildly restricted (20% food restricted group), or esverely restricted diet (40% food restricted group). Rats were killed on the day of 7th, 14th, and 21st of refeeding. Lipogenesis was determined by the amount of glucose converted to the total lipid. Body weight and epididymal adipose tissue weight returned to control states by 5 days in ad libitym group and by 14 days in 20% food restricted group. As expected, in 40% food restriction during refeeding weight and epididymal adipose tissue weight did not rcturn to control states until day 21. On day 21 after refeeding, the serum total cholesterol concentration of ad libitum group was significantly (p<0.05) higher than that of control group. The serum HDL-C concentration of 40% food restricted group during refeeding was significantly (p<0.05) higher than that of control group. However, there were no significant dif-ferences in serum HDL-C/total cholesterol (TC) ratio and trigluceride concentration among the groups. Fasting for 2 days decreased lipogenesis and LPL activity (p<0.05). On day 21 after refecding, the lipogencsis of ad libitum group was significantly (p<0.05) lower than that of control group. The lipogenesis of 40% food restricted group during refeeding was significantly (p<0.05) higher than that of conrtol group. Ad libitum group and 20% food restricted group during refecding allowed heparin-releasable (HR) LPL or total extractable (TE) LPL activity to return to control states. 40% food restricted group during refeeding delayed the return of HR-LOL or TE-LPL activity to return to control states until day 21 of refeeding. These results suggest that food restriction during refeeding can partially or completely prevent the overshoot of LPL activity, and this may influence the rate of lipid accumulation in adipose tissue during refeeding.
