OBJECTS: Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. METHOD: Sleeping time, sleep recordings of EEG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. RESULTS: 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded beta-wave in sleep recording of EEG. In there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. CONCLUSION: These results suggests that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

PURPOSE: Atypical femoral fracture (AFF), periprosthetic femoral fracture (PPFF) and femoral nonunion (FNU) are recalcitrant challenges for orthopedic surgeons. Teriparatide (TPTD) had been demonstrated to have anabolic effects on bone in various studies. We postulated that adjuvant TPTD after operation would enhance biologic stimulation for bone formation. We investigated (1) whether the adjuvant TPTD could achieve satisfactory union rate of surgically challenging cases such as displaced AFF, PPFF and FNU; (2) whether the adjuvant TPTD could promote development of abundant callus after surgical fixation; (3) whether the adjuvant TPTD had medically serious adverse effects. MATERIALS AND METHODS: Thirteen patients who agreed to off label use of TPTD in combination of operation were included in this retrospective case series. Median patients' age was 68.7 years, and there were three male and ten female patients. Their diagnoses were nonunion in six patients and acute fracture in seven. Medical records and radiographic images were reviewed. RESULTS: Twelve of thirteen fractures were united both clinically and radiologically within a year after adjuvant TPTD. Union completed radiologically median 5.4 months and clinically 5.7 months after the medication, respectively. Callus appeared abundantly showing median 1.4 of fracture healing response postoperatively. There was no serious adverse reaction of medication other than itching, muscle cramp, or nausea. CONCLUSION: Even appropriate surgical treatment is a mainstay of treatment for AFF, PPFF, and FNU, the current report suggested that adjuvant TPTD combined with stable fixation results in satisfactory outcome for the challenging fractures of femur.

Routine use of the IVP in preoperative evaluation of patients with obstructive bladder outlet symptoms has been questioned on the basis of the chance of incidental finding in the upper tract and the implication of such findings to management. We studied 220 patients who underwent intravenous pyelography before prostatectomy at Department of Urology, Sanggye Paik Hospital from Oct. 1989 to Jun 1992. Of 220 patients, 183( 83.2% ) showed normal upper tract with cystogram compatible with benign prostatic hyperplasia. Abnormalities were found in 37( 16.8% ) patients but treatment plan was altered in only 5(2.25% ) cases. Most of these abnormalities could be detected on KUB or cystoscopy. Only one(0.45% ) malignancy would have been missed without routine IVP. We conclude that IVP in our opinion should not be performed as a routine procedure in patients with benign prostatic hypertrophy, but only in selected cases.

In the thyroid tissue, thyrotrophin(TSH) and IGF-I played major role of the goitrogen. But the evidences and precise mechanism of these two factors were not known so much. Actually local secretion of thyroid IGF-I was originated from its fibroblasts mainly. We guessed major roles of IGFs in the thyroid tissue were local paracrine effect of thyroid cells proliferation and differentiation which concert with TSH. Recently, some reporters described the source of thyroid IGF-I were partly from thyroid follicular cells and its action were synergistic with TSH. We measured TSH, IGF-I and IGFBP-3 from sera and thyroid cystic fluids in 36 patients with simple thyroid cyst and examined into correlation between TSH, IGF-I and IGFBP-3.1) According to cyst/serum TSH ratio, we classified two groups(Group I; c/s TSH <1, n=19. Group II; c/s TSH >1, n=17). This classification criteria means that cystic TSH level were increased than that of serum or not.2) The serum TSH, IGF-I and IGFBP-3 levels are not difference between group I and II.3) Cystic TSH were dependent on the serum TSH in Group I, but negative correlation in Group II. In Group II, cystic TSH was significant increased.4) Serum IGF-I were positive correlation in each Group5) In Group II, cystic IGF-I was not exceed than those of serum IGF-I, but some cystic IGFBP-3 were more increased than those of serum.6) In Group II, cystic IGFBP-3 increased than serum TSH, and cystic IGFBP-3 was positive correlation with cystic TSH and cystic IGF-I.As these data suggested that cystic TSH and cystic IGF-I levels may influence cystic IGFBP-3 level. The main effect for maintenance of cyst was mediated by cystic TSH and cystic IGFBP-3. But the cystic IGFBP-3 has major role for thyroid cyst than cyst TSH.

PURPOSE: Peritoneal dialysis related peritonitis remains one of the most common causes of hospitalization and discontinuation of peritoneal dialysis. Patient education and the individual environment play a significant role in improving the clinical outcomes. Therefore, this study focused on the preventive effects of practical training on the spot for peritoneal dialysis related peritonitis in continous ambulatory peritoneal dialysis (CAPD) patients. METHODS: Fifty-eight patients who were started on CAPD were as the primary intended treatment modality. The patients were given to a questionnaire regarding their gender, age, place of residence, level of education, economic status, sterile technique, knowledge of personal hygiene, placing a correct region for exchanging a fluid bag, and their duration of CAPD. During a home visit, the patients were instructed in how to sterilize the region of dialysis and maintain sterility in dialysis. RESULTS: Seventy four cases of peritonitis from 35 patients were identified over the 2 year's period. In the rural residences where there is a lower socio-economic status, the rates of peritonitis decreased in those patients who had received training on the spot within 6 months from the start of peritoneal dialysis compared with the patients after the 6 month period. Lower rates of peritonitis were noted in the patients who received training earlier (r=0.19, p=0.03). CONCLUSION: Ongoing and repetitive individualized education is needed to prevent peritoneal dialysis related peritonitis. The incidence of peritoneal dialysis related peritonitis can be reduced by educating these patients individually.

The present study was performed to evaluate the effect of Tetracycline-HCl on the change of implant surface microstructure according to application time. Anodic oxidation surface were utilized. Implant surface was rubbed with 50mg/ml Tetracycline-HCl solution for 1/2min., 1min., 1 1/2min., 2min., 2 1/2min. and 3min. respectively in the test group. Then, specimens were processed for Ra Value test and scanning electron microscopic observation. The results of this study were as follows. 1. The anodic oxidation surface roughness tests don't show significant difference on conditioning with saline and Tetracycline-HCl. 2. The anodic oxidized surfaces showed the craterous structures. The surface conditioning with Tetracycline-HCl didn't influence on its micro-morphology. In conclusion, Anodic oxidation implant surface is stable to detoxificate with 50mg/ml Tetracycline-HCl of implant surface.

Trichinellosis transmission to humans via the consumption of reptile meat is rare worldwide. In Korea, however, 2 such outbreaks, possibly via consumption of soft-shelled turtle meat, have occurred in 2 successive years. In 17 August 2014, 6 patients were admitted to Wonju Severance Christian Hospital complaining of myalgia, fever, and headache. Eosinophilia was the indication of the initial laboratory results, and they were eventually diagnosed as trichinellosis by ELISA. All of the patients worked at the same company and had eaten raw soft-shelled turtle meat at a company dinner 10 days prior to their admission. They were treated with albendazole for 2 weeks, upon which all of their symptoms disappeared. This is the 8th report on human trichinellosis in Korea, and the second implicating raw soft-shelled turtle meat.

BACKGROUND: Up to now, lobectomy, bilobectomy and pneumonectomy combined with extensive lymph node dissection have been regarded as the standard procedures for non-small cell lung cancer (NSCLC). In high-risk patients, however, limited resection (LR) has been attempted as a salvage procedure, and, recently, indication for LR has been extended to selected cases with early-stage NSCLC. MATERIAL AND METHODS: Among the 773 patients who underwent surgical procedures for NSCLC in Seoul National University Bundang Hospital from May 2003 to December 2008, 43 patients received LR. Medical records of these patients were retrospectively reviewed. RESULTS: Mean age at operation was 66.0+/-12.4 years, and there were 30 males. Twenty-five patients underwent conservative limited resection (CLR) and 18 underwent intentional limited resection (ILR). Indications for CLR were multiple primary lung cancer in 9 (9/25, 36%) and severe concomitant diseases in 5 (5/25, 20%). Of these, 6 patients underwent segmentectomy and 19 received wedge resection. During the follow-up period of 28.0+/-17.8 months, 15 patient developed recurrent lung cancer. ILR was selectively performed in lesions almost purely composed of ground glass opacity (> or =95%), or in small solid lesions (< or =2 cm). Of these, 11 patients underwent segmentectomy and 7 underwent wedge resection. During the follow-up period of 31.7+/-11.6 months, no patient developed recurrence. CONCLUSION: Intermediate-term outcome of LR for early-stage lung cancer is comparable to that of standard operation. For the delineation of the indications and appropriate surgical techniques for LR, prospective randomized multi-institutional study may be expedient.
