In the present study the effect of exercise on the conversion rate of ingested glucose to glycogen in the different types of hindlimb skeletal muscles in Sprague-Dawley male rats was studied. The amounts of synthetized glycogen from ingested glucose of fast-twitch white (WV), fast-twitch red (RV), mixed type of fast-twitch white and red (EDL), and slow-twitch (SOL) muscles were determined at 30 and 90 min. after ingestion of 25% glucose solution which contained 14C-glucose(2 ml(luCi)/100gm B.W.) in control and exercise loaded rats. The result was summarized as follows: The about 55% at 30 min. and 70% at 90 min. after glucose ingestion were absorbed from gastrointestinal tract. This result shows no effects of exercise on absorption rate from gastrointestinal tract. The amount of synthetized glycogen of SOL from ingested glucose at 30 and 90 min. after glucose ingestion were highest, whether WV were lowest in hindlimb skeletal muscles in control and exercise loaded rats. In the exercise loaded rats, the amounts of synthetized glycogen of SOL, RV, and EDL at 90 min. after glucose ingestion was much higher than control rats, but not different in WV between exercise-loaded and control rats. At 30 min. after glucose ingestion, only SOL of exercise loaded rats was higher than control rats. In the control rat, the synthesis of glycogen was almost completed during initial 30 minutes. On the other hand, in the exercise loaded rat, except WV was opposite result of control rats, i.e., amounts of synthetized glycogen were major during late period. The amount of synthetized glycogen of liver at 30 and 90 min. after glucose ingestion in exercise loaded rats was higher than control rats. The rate of glycogen synthesis in control and exercise loaded rats were higher between 30-90 minute than initial 30 minutes.

PURPOSE: The purpose of this study was to compare and analyze the results of midfoot arthrodesis with locking plate fixation and the other instruments. MATERIALS AND METHODS: Twenty one patients, a total of 22 feet who underwent midfoot arthrodesis at our institution were reviewed retrospectively from January 2006 to December 2011. Locking plates were used in 9 cases, and the other instruments such as K-wires, screws, staples were used in 13 cases. Radiologic union time was evaluated and compared between both groups. Preoperative & postoperative AOFAS midfoot scores were evaluated and compared as clinical results. RESULTS: The average AOFAS score was rising from 69.7 to 89.4 in locking plate group and from 67.6 to 80.7 in the other instrument group. There was no statistically significant difference in two groups (p=0.179). The mean radiologic union time was 10.2 weeks in locking plate group, 12.6 weeks in the other instrument group with no significant difference (p=0.062). One case of peroneal nerve irritation was detected as a complication in locking plate group. One case of peroneal nerve irritation and 1 case of superficial wound infection with skin sloughing were detected in the other instrument group. CONCLUSION: There was no statistically significant difference for union time and clinical results in both groups. A locking plate can be one of the useful option for midfoot arthrodesis.

Primary ureteral carcinoma is a rare disease comprising 1% of all urinary tract tumors. Primary adenocarcinoma of the ureter is extremely rare. We report a case of primary ureteral adenocarcinoma associated with long-standing ureteral stone in 40-year-old man, who was treated by nephroureterectomy with bladder cupping, with a brief review of the literatures.

Neuroimaging of the brain is useful diagnostic evaluation of patients with hepatic encephalopathy msofar as it is able to exclude other causes of abno rmal mental status. Recently, changes of basal ganglia on MRI characteriwd by increased signal mtensity on Tl-weighted images were reported m patients with liver cirrhosis. Signal abnormality involves mainly the globus pallidus and seems to be specific for patients with chronic liver disease. Its pathogenesis and significance are obscure, and no pathological reports have been made. We experienced 3 cases of Chronic acquired hepatic failure whose MRI showed increased signal in-tensity in the basal ganglia on Tl-weighted imaging. Our findings su-ggest that basal ganglia signal abnormality could arise as a marker of brain impairment related to deposition of an unidentified paramagnetic substance or altered intracellular water relaxation.

The typical attacks of hypokalemic periodic paralysis come on during sleep or at late night. The patients usually awaken to find mild or severe weakness of the limbs and the attacks evolve over minutes to several hours. Once established, the weakness lasts a few several hours in most cases. However, our two patients due to the hypokalemia of renal tubular acidosis showed more prolonged, progressive courses of flaccid, hyporeflexic motor weakness. Especially one patient also showed slowed motor nerve conduction velocities which were normalized after potassium correction of one day. So we initially mistook the motor weakness for Guillian Barre Syndrome.

The purpose of the present study was to determine whether chronic high-fat diet (HF) induces insulin resistance independently of obesity. We randomly divided 40 rats into two groups and fed them either with a HF or with a high-carbohydrate diet (HC) for 8 weeks. Whole body glucose disappearance rate (Rd) was measured using a euglycemic hyperinsulinemic clamp. Firstly, we defined whether insulin resistance by HF was associated with obesity. Plasma glucose and triglyceride concentrations were significantly increased in HF. Rd was decreased (10.6+/-0.2 vs. 9.1+/-0.2 mg/kg/min in HC and HF, respectively) and the hepatic glucose output rate (HGO) was increased in HF (2.2+/-0.3 vs. 4.5+/-0.2 mg/kg/min in HC and HF, respectively). Rd was significantly correlated with %VF (p<0.01). These results implicate that visceral obesity is associated with insulin resistance induced by HF. In addition, to define whether dietary fat induces insulin resistance regardless of visceral obesity, we compared Rd and HGO between groups 1) after matching %VF in both groups and 2) using an ANCOVA to adjust for %VF. After matching %VF, Rd in HF was significantly decreased by 14% (p<0.001) and HGO was significantly increased by 110% (p<0.001). Furthermore, statistical analyses using an ANCOVA also showed Rd for HF was significantly decreased even after adjusting %VF. In conclusion, we suggest that dietary fat per se could induce insulin resistance in rats fed with chronic HF independently of obesity.
