PURPOSE: Anorectal manometry has become a routine investigation for the evaluation of patients with anorectal disorders. However, the interpretation of such studies is confounded by the fact that controversial data are reported with regard to the same events. The aim of this study was to measure the reproducibility of the pressure profiles of anorectal manometry in healthy controls for standardization of their measurements. METHODS: Manometric study was performed on different days with 7 days interval in 22 male healthy subjects with the use of a pneumohydraulic capillary perfusion system. RESULTS: For resting pressures with rapid pull-through (RPT) technique, maximum pressure revealed 43.58, 19.8% and mean pressure, 16.02, 14.6% in the order of reproducibility coefficient and coefficient of variation. For resting pressures with stationary pull-through (SPT) technique, maximum pressure; 17.22, 12.2% and mean pressure; 14.66, 26.4%, respectively. For squeezing pressures with RPT technique, maximum pressure; 53.37, 14.3% and mean pressure; 66.32, 23.6%. For squeezing pressures with SPT technique, maximum pressure; 72.80, 11.9%, mean pressure; 93.10, 30.5% and coughing pressure; 69.42, 15.8%, respectively, For anal canal length (ACL) with RPT technique, at resting state; 7.10, 7.9% and at squeezing state; 14.55, 13.7%, respectively. For high pressure zone (HPZ) with RPT technique, at resting state; 6.68, 16.3% and at squeezing state; 11.06, 23.5%. For HPZ with SPT technique, at resting state; 11.28, 25.4% and at squeezing state; 10.04, 17.5%, respectively. For radial asymmetry (RA) with RPT technique, at resting state; 13.76, 42.3% and at squeezing state; 7.86, 22.9%. For RA with SPT technique, at resting state; 24.6, 58.6% and at squeezing state; 14.28, 46.7%, respectively. CONCLUSION: Measurements of resting and squeezing pressure are more reproducible by SPT technique, in which technique it seems that maximum value is more preferred as a representative value. ACL and HPZ are may well measured on resting pressure with SPT technique. Radial asymmetry shows the best reproducibility on squeezing pressure with RPT.

Rotor syndrome is a rare disease of hereditary hyperbilirubinemia transmitted with autosomal recessive trait. In general, Rotor syndrome shows direct hyperbilirubinemia and there has been several reports since Sons's report in 1966, in Korea. A 34-year-old female was admitted with the chief complaint of intermittent icteric sclera for 24 years. There was no family history of jaundice. Rotor syndrome was diagnosed by oral cholecystogram, BSP retention test, 99mTc-DISIDA scan, liver biopsy and electron microscopy study of liver biopsy specimen. We report this case with brief review of the literature.

Aloe is one of the leading products used in phytomedicine. Several cases of aloe-induced toxic hepatitis have been reported in recent years. However, its toxicology has not yet been systematically described in the literature. A 21-year-old female patient was admitted to our hospital with acute hepatitis after taking an aloe vera preparation for four weeks. Her history, clinical manifestation, laboratory findings, and histological findings all led to the diagnosis of aloe vera-induced toxic hepatitis. We report herein on a case of acute toxic hepatitis induced by aloe vera.

The authors conducted a clinical observation of 55 cases of solitary pulmonary nodules at Yeungnam University Hospital from June 1986 to October 1990, and the following results were obtained: 1. The age distribution was ranged from 18 to 77 years, and the male-to female ratio was 1.8:1. 2. Among 55 cases of nodules, 28 cases were benign and 27 cases were malignant nodules, and of malignant nodules, the primary lung cancer was 23 cases and of benign nodules, 18 cases were tuberculoma. 3. 23 cases (41.8%) was asymptomatic and the other 32 cases were symptomatic; chest pain 12 cases, hemoptysis; 8 cases, cough; 8 cases and dyspnea; 4 cases. 4. The non-smoker-to-smoker ratio was 1:1.04, but among 23 smoker over 20 pack years, 14 cases were malignant nodules. 5. According to nodular size, there is no striking differences between benign and malignant nodules except 3-4 cm sized nodules. 6. The lobar distribution of nodules, 35 cases were in the right lung (upper lobe; 14 cases, middle lobe; 11 cases, and lower lobe; 10 cases) and 23 cases were in the left lung (upper lobe; 9 cases, lower lobe; 11 cases), and the malignant nodules were most commonly observed in the right upper lung.

OBJECTIVE: The aim of the present study was to investigate the effects of nitric oxide synthase (NOS) inhibitor on MK-801-elicited behaviors in rats in an attempt to elucidate the participation of NO in the pathophysiology of schizophrenia and to identify the possibility of NOS inhibitor's antipsychotic property. METHODS: Male Sprague-Dawley rats, weighing 250-300g, were given MK-801 in order to know behavioral changes induced by MK-801. Next time, animals were pretreated with Nomega-nitro-L-arginine (L-NA) as a NOS inhibitor and haloperidol before administration of MK-801, respectively. Separate behavioral rating scales were introduced for quantifying MK-801-induced locomotor activity, stereotyped behaviors and ataxia in order that these behaviors might be assessed independently. Animals were observed for 30 seconds and scored once every 10 min. during a period of 1 hour. RESULTS: 1) Locomotor activity and stereotyped behavior were significantly increased by MK-801 in rats. 2) Locomotor activity and stereotyped behavior were significantly diminished by pretreatment with haloperidol. 3) Locomotor activity and stereotyped behavior were also significantly diminished by pretreatment with L-NA. CONCLUSIONS: These findings suggest that NO may, in part, mediate behavioral changes induced by MK-801, and that inhibitors of NOS may have antipsychotic action.

In the summer of 1969 from July through October, authors carried out a study of susceptibility in adult female bed bug(Cimex lectularius) in order to ascertain any development of resistance to insecticides in Korea. The test to DDT and Dieldrin was performed in laboratory by the continuous exposure of residues method, with standard impregnated paper used for adult mosqitoes. Some results so far obtained can be summarised as follows: LC(50) were 2.839% in DDT and 0.167% in Dieldrin. The resistance has been arisen 2.4-2.9 times in DDT and 1.6-2.4 times in Dieldrin as compared with London laboratory strain, but they were susceptible 1.4 times in DDT and 180 times in Dieldrin as compared to Israel resistance strain.

In order to observe the changes in left ventricular function during coronary artery occlusion and reperfusion, left anterior descending (LAD) coronary arteries in the anesthetized dogs were occluded for 1 hour and then reperfused for 4 hours. Hemodynamic indexes of global systolic and diastolic function and regional wall thickness changes as a regional contractile index were measured during occlusion and reperfusion. The results were as follows; 1) Indexes of global systolic function (left ventricular peak systolic pressure, peak positive dP/dt) and global diastolic function (peak negative dP/dt, time constant, left ventricular end-diastolic pressure) showed deterioration in early occlusion period (10-30 minutes) but gradually improved even if coronary occlusion persisted. Reperfusion did not induce significant changes except that peak positive dP/dt transiently deteriorated 30 minutes after reperfusion and left ventricular end-diastolic pressure decreased 1.5-2 hours after reperfusion. 2) Indexed of regional function (i.e, end-diastolic thickness and % systolic thickening of anterior left ventricular wall) deteriorated by 10 minutes' occlusion which persisted during the entire occlusion period. Reperfusion induced no significant improvement in regional contractile function compared with occlusion 60 minutes' data, which suggested reperfusion for 4 hours after 1 hour's LAD occlusion may be insufficient for the ischemic region to recover its contractility. 3) Reperfusion arrhythmia (ventricular tachycardia) was noted in most (6/9) of the dogs, one of which deteriorated into ventricular fibrillation and the others spontaneously converted to normal sinus rhythm.
