Glossopharyngeal neuralgia, first discribed by Labat in 1928, is a very rare disease of unknown cause. This neuralgia is associated with a characteristic sharp pain of the posterior pharynx, tonsils and larynx, and especially triggered by swallowing action. It is said that this pain is more severe than that of trigerminal neuralgia and the pain may last several up to 30 minutes and the attack repeats intermittently. Diagnosis of glosspharyngeal neuralgia is made by the symptoms and by the elongation of the right side of the styloid process in this case. The glossopharyngeal nerve block by the deposition of local anesthetic solution is useful in the accurate diagnosis of the douleureux or neuralgia in which this nerve is involved and in providing anesthesia for operative intervention upon the posterior third of the tongue. This is a report of a case of glossopharyngeal neuralgia, which did not respond to Tegretol and other analgesic drugs and treated by glossopharyngeal nerve block with 0.5% bupivacaine l.5-2.0 ml. The block was performed every day for 15 days and the neuralgia disappeared without complication.

The fibrillar coat of Candida albicans is of interest as its significance in antigenicity, antiphagocytosis, and adherence to host tissues. The partial biochemical properties and ultrastructure of fibrillar coat induced by rabbit sera were examined. The induced fibrillar layer was destroyed by treatments of lyticase, proteinase K and dithiothreitol. The total protein concentration of fibrillar cell wall lysate was higher than that of non-fibrillar cell wall lysate, but the total sugar concentration was similar. On SDS-PAGE analysis, the protein profiles between in fibrillar cells and in non-fibrillar cells were shown to be different. In fibrillar cells, the major bands of cell wall lysate were 83, 66, 54, 47, 33, and 26 kDa in dithiothreitol-treated lysate. The proteins of 26 and 19 kDa were predominant in lyticase-treated lysate. Although the fibrillar thickness and protein amount of cell wall lysate were increased in according to the incubation time, the protein profiles did not changed. These results suggest that the proteins of 83, 66, 54, 47, 33, 26, and 19 kDa may be major constituents of fibrillar coat in C. albicans.

This study observed the changes of the glycogen content in extensor digitorum and soleus by electrical stimulation on the sciatic nerve with various frequencies, and the result were compared with those of treadmill running exercise. The results are summarized as follows ; The glycogen content of extensor digitorum longus was greater than that of the soleus in the normal group, and the reducing amount of glycogen content of extensor digitorum longus was greater than that of the soleus by overnight fasting. As the frepuency of electrical stimulation was increased by 2, 5 and 10Hz., the glycogen content of the extensor digitorum longus was slightly reduced or changed minimally. As the loading period of clectrical stimulation was increased to 30 and 90minutes, the glycogen content of extensor digitorum longus was much reduced from early stage, and that of the soleus was the same tendency as the frepuency increased. The glycogen content of the extensor digitorum longus was proportionally reduced by treadmill running excercise, and that of the soleus was much reduced from the early stage. In summary, based on the experimental evidence of this investigation, it showed the different physio-chemical responses of th fast and slow twitch muscle fibers by electrical stimulation, and also not the equal responses of muscle fibers by electrical stimulation and treadmill running exercise.

BACKGROUND: Community-acquired pneumonia(CAP) remains a leading cause of morbidity and mortality worldwide. Recently, the evolution of drug-resistant microorganisms has become a serious problem in CAP management. Specific antimicrobial therapy is the cornerstone of CAP management. However, obtaining an accurate etiologic diagnosis clinically is not easy and empirical antimicrobial treatment is usually administered prior to the correct microbiologic diagnosis. In this study, the clinical usefulness of empirical CAP treatment was investigated. METHODS: A total 35 cases were studied prospectively over a 16-month period in Mokpo Catholic Hospital from Dec. 1995 to Mar. 1997. The microbiologic diagnosis was made by sputum, blood culture, a specific serum antibody test and an immunologic study. RESULTS: The causative organisms were isolated in 10 (30%) out of 33 cases: 8 cases and 1 case on the sputum culture and blood culture respectively, and 1 case by an indirect hemagglutinin test. 12 cases had underlying diseases: pulmonary tuberculosis 4, alcoholism 4, diabetes mellitus 3, and liver cirrhosis 1. Antimicrobial treatment was given empirically and all cases recovered. CONCLUSION: A definite microbiologic diagnosis before commencing the appropriate treatment in CAP is not straightforward. Empirical therapy according to a clinical assessment is important and helpful. However, every effort to make the correct etiologic diagnosis should be taken.

Purpose:
The alveolar ridge preservation (ARP) is widely conducted for implant placement. However, experimental results using deproteinized porcine bone mineral (DPBM) have been scarce. This retrospective study evaluated factors affecting the primary stability of implants in an area where ARP was performed using DPBM.
Materials and Methods:
Thirty-eight patients were divided into two groups based on the primary stability, with torque value of 30 Ncm as borderline. To determine the factors that affect the primary stability of implants, we collected data from patients’ medical records including age, sex, reentry time, socket location, remaining bone wall at the time of extraction, and type of collagen membrane, as well as from radiographs and histomorphometric analysis.Result: The results showed statistically significant difference for the remaining extraction socket wall (P=0.014), residual graft (P=0.029), and fibrovascular tissue (P=0.02) between the two groups. There was an insignificant tendency toward the time of reentry surgery (P=0.052) and location (P=0.077). All implants placed in sites using DPBM functioned well up to 3 years.
Conclusion
Within the limitations of the present study, extraction socket wall, residual graft, and fibrovascular tissue can affect the primary stability at the time of implant placement on grafted sites using DPBM and collagen membranes. In addition, reentry time and locations can be considered. In future studies, comparative experiments in quantified models will be required to supporting the findings.

BACKGROUND: Pacing-induced atrial electrical remodeling (AER) is characterized by shortening of atrial effective refractory period (A-ERP) and its altered rate adaptation. In paroxysmal atrial fibrillation (AF), periods of AF occur with interveneing normal sinus rhythm (NSR) when atria recover from the preceding AER. Previous episodes of AF may precondition the atrial myocardium and cause different time course of AER in subsequent episodes of AF. But the influence of the preceding AER on the subsequent AER has not been described. METHODS: Four mongrel dogs were anesthetized with enflurane. After thoracotomy, silicon band with 3 pairs of electrodes was sutured to the lateral wall of the left atrium. Atrial pacing was performed after 2 wks of recovery and autonomic blockade. Pacing protocol consisted of rapid atrial pacing (RAP) at 500 bpm (for 60 min) and recovery in NSR (for 60 min) which was repeated three times. A-ERP was measured every 10 min. The same pacing protocol was repeated after pretreatment with verapamil (0.1 mg/kg/hr). RESULTS: 1) With 60 min of RAP, A-ERP decreased significantly (126+/-6 ms vs. 105+/-7 ms, p<0.005). 2) After cessation of pacing, A-ERP returned to 98% of baseline value in 15 minutes. Recovery from AER occurred faster than AER (78 vs 21 ms/h). 3) After pretreatment with verapamil, RAP decreased A-ERP from 127+/-5 ms to 116+/-5 ms. AER, the reduction in A-ERP, was significantly attenuated by pretreatment with verapamil (deltaERp=17+/-7 vs. 9+/-0.2 %, p<0.05). 4) When RAPs were repeated, AER showed a tendency of acceleration, but it was not statistically significant (deltaERp=22 ms, 24 ms, 28 ms at the end of 60 min pacing for the 1st, 2nd, 3rd pacing). CONCLUSION: RAP induced AER in conscious dog atria and it was reduced by pretreatment with calcium channel blocking agent, verapamil. Upon repeated atrial stimulations, AER did not accelerate or decelerate when the atria recovered from the preceding AER.

Fiberoptic bronchoscopy is a valuable diagnostic and therapeutic procedure in many clinical situations and is relatively simple to perform with proper technique. Local anesthetic technique is often preferable to general anesthesia for bronchoscopies since these examinations are mostly undertaken as outpatient procedures. Inhaled topical lidocaine, used to produce anesthesia of the repiratory tract prior to bronchoscopy, may cause anaphylactoid reaction in patients. However lidocaine hypersensitivity reaction is uncommon. We report the case of death due to hypersensitivity to topical lidocaine spray given during routine premedication for this procedure. The possibility of bronchospasm secondary to an adverse reaction to premedication or anesthesia must also be considered.
