Sixty patients anesthetized with nitrous oxide-oxygen-halothane, who received pancuronium for the maintenance of muscular relaxation were divided into three group of twenty each. Ath the end of anesthesia, the patients of Group l received in 1.0mg atropine travenously and neostigmine 2.0mg: those in Group ll glycopyrrolate 0.4mg and neostigmine 2.0mg. and those in Group lll atropine 0.5mg, glycopyrrolate 0.2mg and neostigmine 2.0mg. After that the changes in heart rate, arrhythmsia, blood pressure and oropharyngeal secretions were observed and evaluated. The results are as follows: 1) The safety and effectiveness of all groups in antagonizing the muscarinic actions of neostigmine were demonstrated. 2) Glycopyrrolate produced a significantly smaller change in heart rate than atropine. 3) There were no significant difference in the indicence of severe tachycardia in all groups respectively. 4) Glycopyrrolate is superior to atropine in the antisalivary action. 5) There were no more advantages in combined use of atropine and glycopyrrolate than that of atropine or glycopyrrolate separotely.

Objectives: Mucous retention cysts and pseudoantral cysts are mainly located within the floor of the maxillary sinus. Most of these maxillary cysts are asymptomatic and often only require observation. However, the presence of these benign maxillary cysts may create problems when maxillary sinus all types of implants are needed. Various treatment methods have been introduced. The selected treatment option depends on the type, size, and location of the cyst and its symptoms. Patients and Methods: The case reports of four patients with maxillary cysts were reviewed retrospectively. These patients received a sinus lift between January 2016 and October 2021 at the Wonkwang University Dental Hospital. Results: To reduce unnecessary operations and the duration of treatment, a conservative treatment method is required. A sinus lift in the presence of maxillary cyst will not typically cause sinus problems if the lifted sinus membrane does not interfere with ventilation of the maxillary sinus. Conclusion When proper treatment is provided, sinus perforation during a sinus lift performed in the presence of maxillary cyst and contamination of bone graft materials by cystic fluid does not necessarily result in adverse outcomes.

It is a frequently asked question who was the driver of a vehicle when a traffic accident occur. To give an expert opinion who was the driver of vehicle, expert witness must inspect not only trace evidences remained in vehicle and occupant's clothing but also occupant's injuries. Thus, the collaboration of forensic engineering and forensic medicine is very fruitful in this kind of case. Due to open sitting position of occupants, deciding the driver of motorcycle is a very difficult and case dependent problem and it is very rare that the driver of motorcycle can be decided only by the estimation of occupant's injuries. In this report, we introduce the case that the driver of motorcycle can be decided by the collaboration of forensic engineering and forensic medicine.

Eosinophilic gastroenteritis (EG) is a rare disease characterized by massive eosinophilic infiltration of gastrointestinal tissue, peripheral eosinophilia, and nonspecific gastrointestinal symptoms. The mucosal type of EG commonly presented with malabsorption and anemia. However, the role of food allergy as a stimulus to EG has not yet been clearly defined. A 27-year-old man was referred to the Emergency Department with dyspepsia and leg swelling. The initial laboratory test should as follows: hemoglobin level, 6.4 g/dL; white blood cell count, 7,400/microL with 24.4% of eosinophil fraction; serum total protein, 3.9 g/dL; albumin level, 2.8 g/dL. Gastric endoscopy ruled out gastrointestinal bleeding showed multiple nodular raised lesions on the gastric antrum, which revealed increased eosinophilic infiltration (above 100/high power field). He had experienced nausea whenever eating beef, porks or fish. High serum specific IgE levels to offending foods (beef, 0.82 kU/L; pork, 0.83 kU/L; egg white, 0.40 kU/L; egg yolk, 0.54 kU/L; milk, 0.81 kU/L) were noted. He was instructed strictly to avoid food allergens with oral prednisolone therapy. Approximately 6 months after offending food restriction, the eosinophil count fell down to 400/microL, the hemoglobin level was returned to 11.5 g/dL and the serum albumin level was increased to 4.1 g/dL. We report a case of EG caused by multiple food allergy which leads to malabsorption and iron-deficiency anemia.

PURPOSE: A physical therapy, with extracorporeal magnetic innervation (ExMi) treatment, has recently substituted direct electrical stimulation for the treatment of many diseases. The efficacy of ExMi treatment was evaluated as a new therapeutic modality in chronic pelvic pain syndrome. MATERIALS AND METHODS: In 30 patients, diagnosed as NIH type III prostatitis, the efficacy of an ExMi was evaluated. Each treatment session was composed of 10 min at 40Hz, 2 min rest and 10 min at 50Hz, with an on-off ratio of 5sec:5sec. Both before and after the completion of 8 sessions of ExMi treatment, self-administered (NIH-CPSI) questionnaire were recorded to assess the changes of patient's symptoms. Three months after treatment, any recurrence was evaluated in patients with symptom improvements of 30% or more by telephone interviews. RESULTS: The mean age of the patients and number of treatment sessions were 39.3 years and 10.5, respectively. Following the ExMi treatments, 20 of the 30 patients (66.7%) experienced a 30% or more improvement of their symptoms. The total NIH-CPSI score was significantly improved, from 23.7 to 15.2 (p<0.01). Each domain of the NIH-CPSI was improved as follows: pain, from 11.37 to 6.77; urination, from 5.03 to 3.27 and the effect on the QOL (quality of life), from 7.27 to 5.17. In responding patients, the improvement remained in 72% of the patients for 3 months after completion of the treatment. CONCLUSIONS: These results suggest that ExMi is an effective and useful tool in the management of chronic pelvic pain syndrome. In chronic pelvic pain syndrome patients, ExMi treatment has advantages over other treatment options due to its easy, comfortable, non-invasive nature.

BACKGROUND: Subcapital femoral neck is known to cause many complications, such as avascular necrosis (AVN) of the femoral head or nonunion, compared with other femoral neck fractures. The purpose of this study was to analyze the incidence of AVN and fixation failures in patients treated with internal fixation using cannulated screws for the subcapital femoral neck fractures. METHODS: This study targeted a total of 84 cases of subcapital femoral neck fractures that underwent internal fixation using cannulated screws. The average follow-up time after surgery was 36.8 months (range, 24 to 148 months). RESULTS: Nine hips (10.7%) showing AVN of the femoral head and 6 hips (7.1%) showing fixation failures were observed. The factors affecting the incidence of AVN of the femoral head after sustaining fractures correlated well with fracture types in the Garden classification (p = 0.030). The factors affecting fixation failure were the degree of reduction (p = 0.001) measured by the Garden alignment index and firm fixation (p = 0.009) assessed using the technique of 3-point fixation through the inferomedial cortical bone of the femoral neck. CONCLUSIONS: The complication rates for subcapital femoral neck fractures were lower than those previously reported; hence, internal fixation could be a primary treatment option for these fractures.

The B-type gamma knife unit was installed at Kyung-Hee University Hospital in March 1992. The selective beam plugging method can be used to reduce the low percentage isodose profiles of normal sensitive organ and to codify the isodose cuties of treatment volume for better shaping of the target volume. For representing the changes of the law percentage isodose profiles, the variations of dose distribution for several cases were discussed in this paper. The film dosimetry was performed for the evaluation of calculated isodose profiles predicted by KULA dose planning system. The results were verified by RFA-3 automatic densitometry. The clinical application of selective beam shielding method was performed in 17 patients in 100 patients who have undergone gamma knife radiosurgery for a year. The calculated and the measured isodose profiles for the high percentage regions were well consistent with each other. When the target of pituitary tumor is macro-size, the selective beam shielding method is the most applicable method. When the target size, however, is small, the correct selection of the proper helmet size is very important. All patients were exposed almost about 3~12 Gy for brain stem, and 3~11.2 Gy for optic apparatus. It is recommended that the same or other plugging patterns with multiple isocenters should be used for protection of the radiosensitive normal structures with precise treatment of CNS lesions.

BACKGROUND: It has been known that Ginseng extract causes the hypotensive action while it rather produces the hypertensive action. Some studies have suggested that Ginseng extract causes a biphasic response on blood pressure, namely, transient fall followed by prolonged elevation. It has been also shown that administration of Korean Red Ginseng powder has no effect on blood pressure in normotensive and hypertensive rats. The present study was designed to examine the effect of total Ginseng saponin on contractile responses of vasoconstrictors in the rat aorta and to establish the mechanism of its action. METHODS: The ring segment of aorta was mounted in a muscle bath filled with oxygenated Krebs solution for the measurement of isometric tension. After the equilibration period, under the presence of total Ginseng saponin, isometric tension induced by some vasoconstrictors were observed and compared to the control responses. The data were expressed as % of the control tension. RESULTS: Phenylephrine (an adrenergic alpha1-receptor agonist) and high potassium (a membrane depolarizing agent) caused greatly contractile responses in the rat aorta, respectively. However, in the presence of total ginseng saponin (600 g/ml), the contractile responses of phenylephrine (10(-6) and 10(-5) M) and high potassium (3.5 x 10(-2) and 5.6 x 10(-2) M) were markedly potentiated whereas prostglandin F2alpha(5 x 10(-6) M)-induced contractile responses was not affected. The contractile responses induced by phenylephrine (10(-5) M) and high potassium (3.5 x 10(-2) M) even under the presence of total ginseng saponin (600 g/ml) were greatly inhibited by the pretreatment of nicardipine (10(-6) M), a calcium channel blocker. CONCLUSION: Taken together, these experimental results suggest that total ginseng saponin can enhance the contractile responses evoked by stimulation of adrenergic alpha1-receptor and the membrane depolarization in the isolated rat aortic strips, which seems to be associated to calcium influx.
