The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.

We have studied the genetic differences among four isolates of Trichinella including a new strain of Trichinella spiralis (ISS 623) recently found from a human case who took a badger in Korea. Because they have a different host origin and came from geographically separated regions, we supposed the genetic pattern of the isolates might be different as had been previously reported. It was analysed by PCR-RFLP analysis of the rDNA repeat that can readily distinguish a species or strain from others. Isolated genomic DNA of each isolate of Trichinella larvae was amplified with ITS1 specific primers and digested with restriction endonucleases. The PCR product of ITS1 was confirmed using Southern blot analysis to be a 910 bp fragment. The restriction fragments of each isolate had variable patterns when it was digested with Rsa 1 only. According to the RFLP patterns, the estimated genetic divergence between each isolate was different. In conclusion, four isolates of Trichinella including a new strain of T. spiralis obtained from a Korean patient may have genetic differences in the ITS1 region and the Shanghai isolate was genetically more similar to the Japanese unknown isolate than others in the ITS1 region.

PURPOSE: This study aimed to investigate the impact of nursing professionalism on the nursing performance and retention intention among psychiatric mental health nurses. METHODS: As a descriptive correlational study, this study sampled 206 psychiatric mental health nurses in six hospitals in Seoul and Gyeonggi area through convenience sampling. Data were collected from March 2 to 31, 2009 using a self-report questionnaire. The collected data were analyzed using SPSS WIN 16.0. RESULTS: In the subscales of professionalism, the 'Sense of calling' had the highest mean score while the 'Professional organization' had the lowest mean score. A significant positive correlation was observed in nursing professionalism, nursing performance and retention intention. According to an analysis on the impact of each subscale of nursing professionalism on nursing performance and retention intention, the 'Sense of calling' and 'Autonomy' were the most significant predictor variable. CONCLUSION: The results confirmed that the improvement of psychiatric mental health nurses' professionalism increases their nursing performance and retention intention and the 'Sense of calling' and 'Autonomy' are critical prediction factors. It is necessary to come up with a strategy which strengthens nursing professionalism in order to improve psychiatric mental health nurses' performance and retention intention.

BACKGROUND: Antimuscarinic agents are used to block undesirable muscarinic effects of `anticholinesterase given to reverse the residual neuromuscular blockade produced by muscle relaxants. However, besides antimuscarinic effects, atropine was known to have some positive effects on the recovery from neuromuscular blockade by acting at the presynaptic muscarinic receptor of the neuromuscular junction. But there have been few reports about the neuromuscular effects of glycopyrrolate. So we observed the neuromuscular effects of atropine and glycopyrrolate, and compared two. METHODS: Mivacurium(0.064 mg/kg) was administered intravenously and the experimental groups were divided into 5 groups: the control group (no antimuscarinic agent administered), Al group (0.02 mg/kg atropine administered), A2 group (0.04 m atropine administered), Gl group (0.01 mg/kg glycopyrrolate administered) and G2 group (0.02 mg/kg glycopyrrolate administered). The left cammon peroneal nerve was stimulated by the 0.1 Hz single twitch and 100 Hz tetanic stimuli. We manitored the mechanical activity of the anterior tibialis muscle and observed recovery index, tetanic fade, and post-tetanic potentiation. RESULTS: There were no significant differences in recovery indices and post-tetanic potentiations among the 5 groups. Significant differences were found in tetanic fades between the experimental groups(A1, A2, Gl, G2) and the control group(P<0.05). However no significant differences in tetanic fades were found among the experimental groups. CONCLUSIONS: Atropine and glycopyrrolate hastened the recovery from mivacurium induced neuromuscular blockade. The neuromuscular recovery effects of glycopyrmlate were found to be similar to atropine at equipotent dose.

BACKGROUND: Several reports have indicated that heparin has a bronchodilative effect in asthma patients, and that it enhances airway smooth muscle contraction in vitro, protamine is known to inhibit or enhance contraction of tracheal smooth muscle. Thus the effects of protamine and heparin on airway smooth muscle contraction are not consistent. However, no report is available on the effects of enflurane on heparin and protamine tracheal smooth muscle contraction. We performed this study to evaluate the effects of heparin or protamine on the carbachol induced contraction of tracheal smooth muscle in the guinea pig. And we also evaluated the effects of enflurane on heparin or protamine induced tracheal smooth muscle contraction. METHODS: Isolated tracheal rings of the guinea pig were suspended in Krebs solution. Contractions were recorded isometrically using a transducer. Contraction was induced by carbachol (10-6 M) and then cumulative dose responses of heparin or protamine (0.006 mg/ml, 0.02 mg/ml, 0.06 mg/ml, 0.2 mg/ml, 0.4 mg/ml) and in heparin (E) group and protmine (E) group, enflurane (4.34%) was administered for 15 minute after carbachol adminstration. RESULTS: Contraction by carbachol was inhibited by level of heparin or protamine at concentrations of 0.2 mg/ml and 0.4 mg/ml. At an enflurane (4.34%) contraction was inhibited, and no further inhibition of contraction by heparin or protamine was observed. CONCLUSIONS: Heparin or protamine inhibited the tracheal smooth muscle contraction induced by carbachol at 0.2 mg/ml and 0.4 mg/ml, and no further significant inhibition of contraction by heparin or protamine was observed after enflurane administration (4.34%).

BACKGROUND: Previous studies have suggested that pityrosporurr yeasts, normal resident flora of skin, may be important in the pathogenesis of dandruff seborrheic dermatitis and confluent and reticulated papillomatosis. OBJECTIVE: We investigated the incidence and distribution of pityiosorum yeasts on clinically normal skin as a more reasonable method for providing the basic data or proving the relationship of pityrosporum and pathogenesi, of the diseases. MEHTODS: A total of 350 subjects were studied. Skin scrapings were stained with 20% Parker ink-KOH(P-KOH) solution. The numbers of pityrosporum spores and hyphe per high power field( x 400) were counted and designated according to a new grading method using bacterial index(BI) of lepra bacilli. RESULTS: The incidence rates of pityrosporum orbiculare(p. orbiculare) and pityrosporum ovale(p. ovale) were 60-70% and 20-50% of subjects respectively on seborrheic area., The incidence of p. orbicilare was highter than that of p. ovale on all examined sites except for the iterior scalp. And pityrosporal hyphae was present on anteriand posterior scalp and earwax in 24-25% of subjects respectively. The incidence of pityrosporum was higher in summer than other seasons The incidence rate of p. orbiculare and hyphae in the group aged below 9 (except neonates) and above 60, were lower than that of other age groups. The inciderice rates and distribution of grades of pityrosporum of neonates were lower than those of older subjects. CONCLUSION: The results of this study showed that the incidence and distribution of pityrosporum spores were similar to previoureports and hyphal forms were found 25% approximately on clinically normal skin of the scalp and carwax. The significance of the presenet of pityosporal hyphae and the relationship between normal skin and pityrosporal hyphae are to be firther elucidated.

BACKGROUND: Cyclosporine, an immune suppressive agent has been reported to potentiate the neuromuscular blockade induced by vecuronium and atracurium. And the potentiation degree was more prominent in the vecuronium. Rocuronium and mivacurium have been introduced into clinical practice recently and there is no report whether the cyclosporine potentiates the neuromuscular blocking effects of these agents. We, therefore studied the effect of Sandimun (cyclosporine in cremophor-ethanol) on the neuromuscular blockade action of rocuronium and mivacurium in rabbits. METHOD: The effect of Sandimun on the rocuronium and mivacurium were investigated in anesthetized 30 rabbits. The rabbits were divided into five groups; rocuronium group (rocuronium bromide 1 mg/kg iv), rocuronium - Sandimun group (rocuronium bromide 0.1 mg/kg iv after Sandimun 5 mg/kg iv), mivacurium group (mivacurium chloride 0.064 mg/kg iv), mivacurium - Sandimun group (mivacurium chloride 0.064 mg/kg iv after Sandimun 5 mg/kg iv) and Sandimun group (Sandimun 5 mg/kg iv). Neuromuscular block was assessed by measuring the response of anterior tibial muscle to 0.1Hz single twitch stimulation of the common peroneal nerve. Onset time, duration of muscle relaxation and recovery index were compared among the groups. RESULTS: There were no significant differences in onset time and recovery indices among the groups. Significant difference was found in duration between the rocuronium group and the rocuronium-Sandimun group (p<0.05). CONCLUSION: Sandimun potentiates the rocuronium - induced neuromuscular blockade but not the neuromuscular blocking action of mivacurium.

It is a highly risky procedure to perform general anesthesia on a patient with toxemia in whom the function of the vital organs is seriously impaired. The risk is much increased when pulmonary edema is also a complication. Recently, many physicians are increasingly interested in PEEP(positive end-expiratory pressure) as a valuable therapeutic approach for pulmonary edema. There are reports that the PEEP has contributed a great deal of the treatment of the pulmonary edema. This is a case report of a patient with toxemia and pulmonary edema who underwent cesarean section. She was treated with oxygen, diuretics, digitalis, steroids, bronchodilators and PEEP(pr.=10cm.H2O, Vt=700ml., assist mode), The therapeutic result was excellent.

Ketamine, a phencyclidine derivative, has been used as an anesthetic agent since 1965 and it has received much attention as an anesthetic for minor surgical procedures, in some diagnostic procedures in children or as an induction agent for poor risk patients. A troublesome problem has been psychic disturbance on emergence. There are many reports on ketamine anesthesia but some cases describing the failure of recommended doses of ketamine to produce adequate analgesia have been reported with cerebral cortical disease or massive craniocerebral trauma. In this case, we experienced a failure to produce adequate analgesia with intramuscular ketamine (11 mg/kg). It was not confirmed in this case whether the patient had suffered any cerebral cortcial disease or not.
