The category of striatal complex contains caudate nucleus, putamen, nucleus accumbens septi, and olfactory tubercle. The striatal complex is composed of two compartments, dorsal and ventral striatum. In the striatum, cholinergic neuron is known as one of the most important intrinsic neurons, but there were little morphological reports about the early postnatal expression of mouse striatal cholinergic neurons. So, we planned to investigate the distribution of mouse striatal cholinergic neurons in their early postnatal period by the immunohistochemistry. We used ICR mouse as the experimental animals and divided them into 5 groups according to their postnatal age : 3-day, 1-week, 2-week, 4-week, and 6-week. Immunohistochemistry was done with anti-choline acetyl transferase antibody (chemicon). The results were as follow. 1 The striatal cholinergic neurons are already detected in the 3-day group, but the intensity was weak and the expression rate was extremely low. In the caudoputamen, the cholinergic expression rate was increased significantly between 3-day and 2-week. And in the nucleus accumbens septi, it was increased significantly between 1-week and 2-week. 2. The cholinergic expression rates of the adult mouse striatum were similar in both compartments. But, the difference of maturational time was noted. In the dorsal striatum, the cholinergic expression rate was increased significantly in the first postnatal week, but in the ventral striatum, it was approached to the adult level only after second postnatal week. In conclusion, the cholinergic expression rate in the mouse striatum was significantly increased after birth. And it was approached nearly to the adult level after 2-week of postnatal age. But, according to the compartments or rostrocaudal subdivisions, the difference of maturational time was noted.

Recent development in thepolymerase chain reaction (PCR) has brought an extraordinary opportunity for the rapid detection of M. tuberculosis in clinical specimens for the diagnosis of tuberculosis. Pneumoconiosis is a sort of pulmonary fibrosis consequent to inhalation of the respirable dust. The association between pulmonary tuberculosis and pneumoconiosis is well recognized. There is a 10-fold increase in the tuberculosis risk among the workers who have pneumoconiosis demonstrated by chest roentgenogram. The physicians managing the patients with pneumoconiosis have to maintain a high index of suspicion for the development of mycobacterial infection, since the diagnosis of tuberculosis is often difficult. Mycobacterium tuberculosis is a very slow growing organism and acid-fast bacillus (AFB) staining frequently shows false negative results, and therefore PCR would be a very rapid, easy and sensitive diagnostic method for the diagnosis of Mycobacterium tuberculosis in pneumoconiotic patients. To compare the PCR method with the conventional methods in diagnosing Mycobacterium tuberculosis in sputum, we used the sputa of 115 pneumoconiosis patients in Munkyeong Cheil Hospital. Of 32 pulmonary tuberculosis in the pneumoconiosis patients, 29 were PCR positive and were higher than 28, 20 positive by culture and AFB stain. Overall sensitivity, specificity, and which were 90.6, 91.5 % respectively for the PCR assay, 87.5, 100 % for the culture method ; 62.5, 98.7 % for the AFB stain. The PCR assay is a rapid, efficient, sensitive method which can detect M. tuberculosis directly in pneumoconiosis patients, and further study should be followed for the development of the easier method.

Genotoxic agents can induce various DNA lesions. DNA-Protein Crosslinks(DPCs) were known as the important DNA lesions which could impair gene expression because DPCs had a high probability of resisting repair and persisting through cell cycle. This repair resistance of DPCs could have biological significance but had not been evaluated clearly yet. Most of the studies that have evaluated the repair of DPCs only compared the extent of DPCs repair with other DNA lesions. We injected K2CrO4, a genotoxic agent, into Sprague-Dawley rats intraperitoneally(5mg/kg) and isolated blood lymphocytes 12 hours later. These lymphocytes were cultured in the mitogen added growth media and mitogen free media separately. The degree of the repair of DPCs was monitored for 4 days by the K-SDS assay. 4 day later, the amount of DPCs decreased by 4.6% in the mitogen added media but in creased by 10.9% in the mitogen free media. These results showed that DPCs induced by K2CrO4 were not repaired easily and the DPCs were biologically significant DNA lesions. We thought the decrease of DPCs in the mitogen added media was not due to the repair of DPCs, but from the increase of normal cell proliferation. Therefore, it is very important to consider the proliferation of normal cells when estimating the repair of DPCs.

OBJECTIVES: Our aims of this study is to analyze the clinical characteristics and the prognos is of the disease which develops in patient swith chronic liver disease as acutely exacerbated hepat it is accompanied by myosit is. Finally we try to identify and is olate the causative agent. METHODS: The patient swith chronic liver diseases, who developed muscle weakness and paralysis, were classified to group A or group B, according to the level of creatinine kinase ( CK) activity. The group A consists of patients with less than 3-fold increase of normal CK activity and the group B includes patients with over 3-fold increase of it. We evaluated clinical characteristics, blood chemistry, clinical course, and causes of deathin patients of study groups, compared with those of patients with chronic liver disease with normal CK activity as controls. The causative agent was suggested by conventional culture and RT-PCR analysis in two cases of group B. RESULTS: 1. There was no significant differences in age, sex, underlying disease, or liver function test bet ween control and study group ( control and group A or B) before entry. 2. The clinical symptoms and signs , such as drowsy mental state, generalized weakness/myalgia caused by hepatic encephalopathy and myositis , occurred frequently in the study group. 3. Significant elevation of aspartic acid transaminase (AST ) and alaninetr ans aminase ( ALT ) was noted in Group B. AST / ALT ratio is over 2 in group A or B. Synthetic function of the liver such as prothrombin time ( PT ) or serum albumin level is significantly decreased. Blood urea nitrogen ( BUN) and creatinine were increased as a result of impaired renal function. 4. Culture of coxs ackievirus was positive by immunofluor escence as say IFA) as a caus ative agent and also was positive in reverse transcription-polymerase chain reaction (RT-PCR) analys is using universal primer of enterovirus in two recent cases of group B. 5. Death rate increased significantly in study group, compared with that of control group ( 20.7% versus 5.6%). Major cause of death, 12 patients died of which, is hepatic failure. CONCLUSION: The patients with chronic liver disease abruptly developed a exacerbated hepaticdys function and muscle paralysis and/or weakness. This exacerbated hepatitis accompanied by myositis was suggested to be caused by coxsackie B viral infection. Furthermore, this infection increase deathrate and resulted in poor prognosis. Thus, further study should be continue to confirm the causative agent and classify the subtype.

Closed medullary nailing has become increasingly popular in the management of fractures of the femur because of a high rate of union, a low rate of complications, and excellent return of function. But it requires good facility and excellent surgical skill. The authors experienced two cases of iatrogenic femur neck fracture during closed medullary nailing of femur shaft fracture.

Ipratropium bromide (IP) is a new anticholinergic bronchodilator. To evaluate its effect on bronchial asthma which is still unknown in Korea, a double blind and randomized study was done on all patients of bronchial asthma who visit out-patients clinic of out department from June to September 197 and showed 75 to 100% of FEV1/FVC ratio on prebronchodilator spirometry (pre BD). The selected patients were given 2 puffs of Fenoterol (FE) or Ipratropium inhalator blindly and Spirometry. The repeated results are: 1. In both FE and IP groups, there was a significant bronchodilatory effect on 5 and 60 minutes after administration. 2. One 5 minutes, effect of FE was significantly greater than IP (FVC p<0.05, FEV1 p<0.01). 3. One 60 minutes, effect of IP was slightly less than FE but statistically non-significant. On the basis of above results, we concluded that onset of effect of IP is slower than FE, but its effect is significant and nearly comparable to FE.
