OBJECTIVE:
The purpose of this study was to predict the optimal bending angles of a running loop for bodily protraction of the mandibular first molars and to clarify the mechanics of molar tipping and rotation.
METHODS:
A three-dimensional finite element model was developed for predicting tooth movement, and a mechanical model based on the beam theory was constructed for clarifying force systems.
RESULTS:
When a running loop without bends was used, the molar tipped mesially by 9.6° and rotated counterclockwise by 5.4°. These angles were almost similar to those predicted by the beam theory. When the amount of tip-back and toe-in angles were 11.5° and 9.9°, respectively, bodily movement of the molar was achieved. When the bend angles were increased to 14.2° and 18.7°, the molar tipped distally by 4.9° and rotated clockwise by 1.5°.
CONCLUSIONS
Bodily movement of a mandibular first molar was achieved during protraction by controlling the tip-back and toe-in angles with the use of a running loop. The beam theory was effective for understanding the mechanics of molar tipping and rotation, as well as for predicting the optimal bending angles.

Ulcerative colitis has been recognized as a premalignant condition because a considerable proportion of patients with colitis eventually develop colorectal carcinoma at the site of the inflammatory disease. Malignant lymphoma occurring in cases of long-standing ulcerative colitis is rare. Cancer risk is positively correlated with duration and anatomic extent of colitis, but do not appear to be increased by early age at onset of disease. Patients with chronic ulcerative colitis should have periodic rectal and colonoscopic biopsies, and those with moderate to marked dysplasia require colectomy because of the increased risk of colon carcinoma. We report a case of malignant lymphoma in patient with ulcerative colitis.

BACKGROUND: Although a brachial plexus block can be used to provide anesthesia and analgesia for upper extremity surgery, its effects using MgSO4 on postoperative pain management have not been reported. The aim of this study was to evaluate brachial plexus block using MgSO4 on postoperative analgesia. METHODS: Thirty-eight patients who were scheduled to undergo upper extremity surgery were randomly allocated into two groups: patients receiving axillary brachial plexus block with 0.2% ropivacaine 20 ml and normal saline 2 ml (group S) or 0.2% ropivacaine 20 ml and MgSO4 200 mg (group M). Before extubation, the blocks were done and patient controlled analgesia was started, and then, the patients were transported to a postanesthetic care unit. The postoperative visual analogue scale (VAS), opioid consumption, and side effects were recorded. RESULTS: The two groups were similar regarding the demographic variables and the duration of the surgery. No differences in VAS scores were observed between the two groups. There was no statistically significant difference in opioid consumption between the two groups. Nausea was observed in three patients for each group. CONCLUSIONS: Axillary brachial plexus block using MgSO4 did not reduce the level of postoperative pain and opioid consumption.

BACKGROUND: Although there are growing evidences linking Chlamydophila pneumoniae infection to myocardial infarction, it remains controversial. The authors intended to assess whether C. pneumoniae infection is associated with myocardial infarction. METHODS: Sera and peripheral mononuclear cells (PMNCs) were collected from 54 cases of acute myocardial infarction (MI), 33 cases of old MI, and 60 normal controls. Anti-C.pneumoniae IgG and IgM antibodies were measured using a microimmunofluorescence (mIF) method, and C.pneumoniae DNA was detected using polymerase chain reaction (PCR). RESULTS: Seropositivity of anti-C.pneumoniae IgM antibody by mIF was shown 5.0% in control group, 29.6% (OR=8.00) in the acute MI and 6.1% (OR=1.23) in old MI group. Seropositivity of anti C.pneumoniae IgG antibody were 60.0 % in control group, 92.6% (OR=8.33) in the acute MI and 87.9% (OR= 4.83) in old MI group. The antibody titers in the acute MI and old MI group tended to be higher compared to those in control group. No C.pneumoniae DNA was detected in any case by PCR. CONCLUSION: The seropositivity and antibody titers were significantly higher in the acute MI and old MI group than in control group, suggesting that C.pneumoniae infection may be a risk factor for myocardial infarction.

In contrast to well-known imaging findings of intracranial epidermoid cysts on magnetic resonance imaging, those of intracranial squamous cell carcinoma (SqCC) are relatively unknown. We present a case of coexistence of intracranial SqCC and epidermoid cyst, with consecutive follow up over 14 months. Based on our case, a solid enhancing portion adjacent to a typically-looking epidermoid cyst may become a clue for coexistence of intracranial SqCC. An initial contrast enhancement and/or heterogeneous signal on diffusion weighted imaging may become a useful diagnostic clue, but more importantly, sudden rapid growth is important in formulating diagnosis.

Pioglitazone (PGZ), a synthetic peroxisome proliferator-activated receptor gamma agonist, is known to regulate inflammatory process and to have neuroprotective effects against neurological disorders. In the present study, we examined the effects of 30 mg/kg PGZ on excitotoxic neuronal damage and glial activation in the mouse hippocampus following intracerebroventricular injection of kainic acid (KA). PGZ treatment significantly reduced seizure-like behavior. PGZ had the neuroprotective effect against KA-induced neuronal damage and attenuated the activations of astrocytes and microglia in the hippocampal CA3 region. In addition, MPO and NFkappaB immunoreactivities in the glial cells were also decreased in the PGZ-treated group. These results indicate that PGZ had anticonvulsant and neuroprotective effects against KA-induced excitotocix injury, and that neuroprotective effect of PGZ might be due to the attenuation of KA-induced activation in astrocytes and microglia as well as KA-induced increases in MPO and NFkappaB.
