The incidence of non-union in the shaft of femur is increasing gradually in spite of considerably improved methods of femoral fracture care. It is necessary that orthopaedic surgeon must draw attention to improve the method of treatment and to prevent the occurance of non-union. This paper presents the follow-up result of 27 cases among 30 established femoral shaft non-union cases, that were treated at the orthopaedic dept. of the National Medical Center from March 1971 to March 1980 by various methods. The study of this series shows the following. l. Amount 27 cases, male was predominant (82%), peak age group was 3rd & 4th decades (52%). 2. The causes of injury were auto-accident (56%), falling down accident (22%), direct blow (11%) & slipping down accident (11%). 3. The most common location was around the mid-shaft of femur (44.4%). 4. The probable causes of non-union were loosening of the implants & metal failure due to improper internal fixation (10 cases), incomplete reduction (7 cases), infection (5 cases) & inadenaute external immobilization (5 cases). 5. Excellent results were obtained by combined method of compression plate, screws & intramedullary nailing with additional autogenous bone graft.

Recently, NAG activity has gained increasing importance as and aid in the diagnosis of renoparenchymal diseases. Elevation of urine NAG activity has been found to be an indicator of renoparenchymnal diseases. To evaluate the diagnostic value of the NAG activity test in the renal disease, we carried out clinical study on 31 cases of renal disease patients who had been admitted to the Department of Pediatrics, Chung-Ang University Hospital between March 1992 and February 1993. We analyese by two data: (1) Stastical Package for the Social Science. (2) Students'T test. The results were as follows 1) The urine NAG activity significantly increased (p<0.05) to 69.9+/-5165.69U/hr/mg Creatinine (U/hr/mg Cr) in the renal disease group compared to 3.6+/-1.91U/hr/mg Cr in the control group. 2) The serum NAG activity was 11.69+/-5.18U/L in the renal disease group and 10.58+/-4.04U/L in the control group. There was no significant difference in the serum NAG sctivity between two groups. 3) In the renal disease group, the serum NAG activity was 10.78+/-3.32U/L in male 12.53+/-6.47U/L in female. There was no significant difference between both sexes. In the renal disease, the urine NAG activity was 33.62+/-30.67U/hr/mg Cr in male and 114.05+/-241.62U/hr/mg Cr female. There was no significant difference between both sexes (p<0.05). 4) In the renal disease group, the urine NAG activity increased 314.73+/-420.39U/hr/mg Cr in the 2 years old group but there was no significant difference of urine NAG activity compared to above 2 years old group . 5) The urine NAG activities were 93.1+/-0193.04U/hr/mg Cr in the poteinuria subgroup and 13.3+/-47.62U/hr/mg Cr in the nonproteinuria subgroup and 3.66+/-1.91U/hr/mg Cr in the control group. There was no significant difference between the proteinuria subgroup and the nonproteinuria subgroup. but there was significant difference between nonproteinuria subgroup and control grouop(p<0.005).

Microglial cell activation is known to contribute to neuropathic pain following spinal sensory nerve injuries. In this study, I investigated its mechanisms in the case of trigeminal sensory nerve injuries by which microglial cell and p38 mitogen-activated protein kinase (p38 MAPK) activation in the medullary dorsal horn (MDH) would contribute to the facial pain hypersensitivity following mandibular nerve transection (MNT). And also investigated the changes of trigeminal ganglion neurons and ERK, p38 MAPK manifestations. Activation of microglial cells was monitored at 1, 3, 7, 14, 28 and 60 day using immunohistochemical analyses. Microglial cell activation was primarily observed in the superficial laminae of the MDH. Microglial cell activation was initiated at postoperative 1 day, maximal at 3 day, maintained until 14 day and gradually reduced and returned to the basal level by 60 days after MNT. Pain hypersensitivity was also initiated and attenuated almost in parallel with microglial cell activation pattern. To investigate the contribution of the microglial cell activation to the pain hypersensitivity, minocycline, an inhibitor of microglial cell activation by means of p38 MAPK inhibition, was administered. Minocycline dose-dependently attenuated the development of the pain hypersensitivity in parallel with inhibition of microglial cell and p38 MAPK activation following MNT. Mandibular nerve transection induced the activation of ERK, but did not p38 MAPK in the trigeminal ganglion. These results suggest that microglial cell activation in the MDH and p38 MAPK activation in the hyperactive microglial cells play an important role in the development of facial neuropathic pain following MNT. The results also suggest that ERK activation in the trigeminal ganglion contributes microglial cell activation and facial neuropathic pain.

Osteomyelitis is an exhaustive disease whose main feature is an inflammation of inner part of bone, bone marrow. In oral and maxillofacial area, we have maxillary and mandibular osteomyelitis and the latter is dominant because of its impaired blood supply. The main cause of osteomyelitis is a bacterial infection and the ways of infections are by periapical odontogenic infection, fracture, post-operative complication, and periodontal disease. The predominant etiologic factor is periapical odontogenic infection mostly caused by advanced dental caries. It is generally believed that periodontal disease could be a cause of osteomyelitis. But periodontal disease is usually confined to the alveolar bone area and not extends to the underlying bone marrow. Accordingly periodontal infection per se rarely cause produce oseomyelitis. Even though osteomyeltis could be occurred by periodontal disease, its virulence of infection is milder than periapical odontogenic infection. So it usually provokes sclerosing or hyperplastic osteomyelitis rather than suppurative type. We had a case of suppurative osteomyelitis caused by periodontal disease and treated it with periodontal and oral and maxillofacial surgical method.

BACKGROUND: Bivalirudin is a direct thrombin inhibitor for patients with unstable angina undergoing percutaneous coronary intervention. METHODS: A sensitive liquid chromatography-tandem mass spectrometry (LC/MS/MS) method was developed and validated for the determination of bivalirudin, in human plasma using nafarelin as internal standard (IS). Chromatographic separation was performed using a Shiseido MG3 mm column (2.0 x 50 mm) with a gradient mobile phase consisting of water and acetonitrile containing 0.1 % formic acid at a flow rate of 0.4 mL/min, and total run time was within 5 min. Detection and quantification was performed by the mass spectrometer using a multiple reaction-monitoring mode at m/z 1091.0 --> 650.3 for bivalirudin, and m/z 662.1 --> 249.3 for IS. RESULTS: The assay was linear over a concentration range of 10 - 10000 ng/mL with a lower limit of quantification of 10 ng/mL in human plasma. CONCLUSION: This method was successfully applied for pharmacokinetics study after intravenous administration of bivalirudin to healthy Korean male volunteers.

Roberts syndrome is an autosomal recessive disorder accompanied by limb defects, craniofacial abnormalities, pre-and postnatal growth retardation. Patients with Roberts syndrome have characteristic premature separation of heterochromatin of many chromosomes and abnormalties in celldivision cycle. We have experienced a case of Roberts syndrome in an immature neonate The patients showed characteristic clinical features of multiple, severe facial mid-line clefts, and tetraphoco-amelia. The brief review of the literlature was made.

This study is an attempt to investigate the effect of total Ginseng saponin (GTS) on the blood pressure of the rat and to elucidate its mechanism of action. GTS, when injeced into a femoral vein of the rat, caused dose-related fall in blood pressure with secondarily elevation of the blood pressure. The depressor effect of GTS was blocked by treatment of atropine and prazosin, but not affected by pretreatment with chlorisondamine or cyproheptadine. GTS inhibited significantly the pressor response evoked by norepinephrine. The pressor effect of GTS was not affected by treatment with atropine or cyproheptadine, but was attenuated markedly by pretreatment with chlorisondamine. From the above mentioned results, it is thought that GTS produces the pressor and the depressor actions in the rat, and that its depressor response is exerted partly through the stimulation of cholinergic muscaric receptors with the blockade of adrenergic alpha-receptors, and that its pressor response is revealed by stimulation of nicotinic receptors in autonomic ganglia.
