The widely used polyethylene glycol (PEG)-based solutions have been proven effective for bowel preparation when 4 L of the solution is administered before colonoscopy. However, large volumes of the solutions are generally poorly tolerated. A new PEG-based solution consisting of 2 L of PEG and a high dose of ascorbic acid has recently become available. Electrolyte abnormalities caused by PEG-based solutions have rarely been reported. We report on a case of acute severe hyponatremia with associated generalized tonic-clonic seizures after bowel preparation with a low-volume PEG plus ascorbic acid solution in a 74-year-old woman with no history of seizures. She took a beta blocker, an angiotensin-converting enzyme inhibitor, and glimepiride for hypertension and diabetes mellitus. She showed general weakness, nausea, agitation, muscle cramping, and seizures after ingestion of the PEG plus ascorbic acid solution. Her serum sodium level was 112 mEq/L. Her symptoms improved after intravenous administration of hypertonic saline. Physicians should pay attention to screening for electrolytes and development of neurological symptoms during bowel preparation.

An 11-year-old girl with a history of two previous attacks of acute pancreatitis was admitted to another hospital. Her epigastrium was tender, and serum amylase was 657 IU/L and lipase 3131 IU/L. Abdominal computed tomography scan suggested necrosis of 30% of the pancreas. Retrograde endoscopic cholangiopancreatography showed a diverticulum covered by normal duodenal mucosa at the second portion of the duodenum, which was separated from the adjacent duodenal lumen by a radiolucent band at UGI series. The apex of the diverticulum was incised endoscopically using a needle knife papillotome. A follow-up endoscopy on the next day noticed bleeding from the incised edge of the diverticulum. Endoscopic hemostasis with hemoclipping and injection of hypertonic saline-epinephrine solution was not successful. The patient was transferred to Kyungpook National University Hospital, and open duodenotomy and excision of the diverticulum were performed. She has recovered well and remains asymptoatic.

Background: Recalcitrant disc herniation may result in chronic lumbar radiculopathy or sciatica. Fluoroscopically directed epidural injections and other conservative modalities may provide inadequate improvement in some patients. In these cases, percutaneous neurolysis with targeted delivery of medications is often the next step in pain management. Methods: An evidence-based system of methodologic assessment, namely, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used. Multiple databases were searched from 1966 to January 2021. Principles of the best evidence synthesis were incorporated into qualitative evidence synthesis. The primary outcome measure was the proportion of patients with significant pain relief and functional improvement (≥ 50%). Duration of relief was categorized as short-term (< 6 months) and long-term (≥ 6 months). Results: This assessment identified one high-quality randomized controlled trial (RCT) and 5 moderate-quality non-randomized studies with an application of percutaneous neurolysis in disc herniation. Overall, the results were positive, with level II evidence. Conclusions: Based on the present systematic review, with one RCT and 5 non-randomized studies, the evidence level is II for percutaneous neurolysis in managing lumbar disc herniation.

Recent studios have shown that narcotic drags produce an unusually intense, prolonged and segmental analgesic action in man whoa injected into the spinal subarachnoid or epidural space (Wang et al, 1979; Behar et al, 1979; Cousins et al, 1979; Magora et a., 1980, Johnston and McCaughey, 1980). Since 1960, many investigators claimed that low molecular weight(LMW) dextran increased the clinical duration of lidocaine(Loder, 1960; Loder, 1962), tetracaine (Chinn and Wirjoatmadja, 1967) and bupivacaine(Kaplan et al, 1975) in man but the mechanism of the action of dextran was unclear. But Curtiss and Scurlock(1979), and Buckled and Fink(1979) claimed that LMW dextran has no effect on the duration of action of bupivacaine in animal studies. The present study was performed to evaluate the clinical efficacy of analgesia by the thoracic epidural injection of morphine and bupivacaine mixture for the relief of pain due to fractured or contused ribs, to evaluate the duration of analgesic effect by the use of the above mixture in a hypertonic solution(dextran 70 or 50% dextrose in water) and to observe the possibility of improvement in the lung function after the pain block. The complications following the pain block were also observed. The 50 single thoracic epidural injections of the mixture were divided into three groups : Group 1(n=15) served as a control group and drags used for the relief of pain were as follows(Mean$\pm$S.D.): morphine($2.13{\pm}1.64\;mg$), 0.5% bupivacaine($3.10{\pm}1.04\;ml$) and 0.9% saline($3.64{\pm}1.11\;ml$). Group 2(n=16) serves as an experimental group and drugs were as follows(Mean$\pm$S.D.): morphine($2.13{\pm}0.72\;mg$), 0.5% bupivacaine($3.06{\pm}0.77\;ml$) and dextran 70($3.75{\pm}1.29\;ml$). Group 3 (n=19) served as an experimental group and drags were as follows(Mean$\pm$S.D.) : morphine($2.42{\pm}0.51\;mg$), 0.5% bupivacaine($3.21{\pm}0.71\;ml$) and 50% dextrose in water($3.58{\pm}1.11\;ml$). The results are were follows: 1) The Dumber of patients who obtained excellent and good analgesic effects following the block were greater in the experimental Croup 2(94%) and Group 3 (90%) than theme of the control Group 1 (80%). 2) The duration of pain relief which lasted more than 3 days after the epidural block was longer in the experimental Group 2 (81%) and Group 3 (75%) than those of the control Croup 1(67%). 3) The pulmonary reserve(FVC%+FEV 1.0%) of 27 cases who were treated by the pain block between 1 and 31 drys following the chest injury was increased to about 13% than those before the block, and that of 13 cases between 32 and 82 days following the chest injury was decreased to about 4% than those before the block. 4) Of the complications following the pain block, there were 5 cased(10%) of nausea within 2 hours following the block, 4 cases(8%) of vomiting after 2 hours following the block, 10 cases(20%) of pruritus after 3~4 hours following the block, 17 cases(34%) of transient urinary retention which tasted 8 to 19 hours, 3 cases(6%) of headache within 2 hoers following the block and 2 cases(4%) of dural puncture. In conclusion, it is suggested that the clinical duration of analgesic effect produced by morphine and bupivacaine mixture can be prolonged by addition of the hypertonic solution to the mixture.

The effect of calcitonin gene-related peptide (CGRP), substance P (SP) and electrical stimulation of the tooth on the intradental nerve activtiy (INA) was investigated in anesthetized cats. The INA was recorded from single pulp nerve units dissected from the inferior alveolar nerve under stereomicroscope. The INA elicited by 3 minute application of 4M NaCl in deep dentinal cavity was compared before and after stimulation at 10 minute intervals. The magnitude of INA was calculated as the total number of nerve impulses produced in given period, and the changes of INA are expressed as % of control INA. The results obtained were as follows. 1. 16 single pulp nerve units were classified as 14 $A{\delta}$-fibers (3.4~19.4m/sec) and 2-fibers (1.5~1.7m/sec) according to the conduction velocity. 2. 4M NaCl evoked an irregular bursts of spikes which continued until washing out. Isotonic saline did not affect INA to subsequent applications of the hypertonic NaCl solution (P>0.05). 3. Local application of CGRP ($200{\mu}g$/ml) in deep dentinal cavity reduced the INA induced by 4M NaCl in $A{\delta}$-fiber units (P<0.01) and some units of those responded to CGRP during application. 4. Local application of SP ($100{\mu}g$/ml) in deep dentinal cavity reduced the INA induced by 4M NaCl in AS-fiber units (p<0.05), but increased the INA in C-fiber unit coincided with large reduction of the INA of $A{\delta}$-fiber units. 5. Monopolar electrical stimulation applied to the crown at intensities high enough to excite C-fibers (12V, 5ms, 10Hz, 10~30min) decreased the INA in $A{\delta}$-fiber units (P<0.01) and systemic pretreatment with phenoxybenzamine (3mg/kg, i.v.) enhanced this inhibitory effect (P<0.01). On the contrary, electrical stimulation increased the INA in C-fiber unit.

The rice variety, Kwanok, was reared in the water, land and salty beds and transplanted to the reclaimed soil area having an average of 0.48% salt concentration 0.67% at the end of April Two levels of $NH_3$-N and urea-N with 6 treatments were used. The effect of each treatment was observed. The plant height of the land bed seedlings at transplanting stage was short but the dry-weight/plant-height ratio was large, and the rooting ability vigorous remarkably after transplantation in the salty area. The total carbohydrate content of the stem part was markedly larger in the land bed seedlings than the others and the C/N ratio was accordingly greater. This tendency was observed through the last rooting stage. In the salty nutrient solution, the roots of salty bed seedlings showed high respiratory activity. The activity of the land bed seedlings did not decreased in the hypertonic solution as much as the water bed seedlings. There was no difference in the effect of fertilization on the rough rice yield between ammonium sulphate and urea. The cultural practices with the land and salty bed seedlings increased the rough rice yields by 33% and 22% respectively, compared with the yields of the water bed Seedlings. The number of panicles, panicle weight and the number of grains per panicle were much greater from the rice plant grown by the land bed seedlings than from the other bed seedlings.
