  • The pharmacokinetics and relationship between in vitro dissolution and in vivo fraction absorbed were investigated after intravenous(iv) injection of omeprazole(OMZ), oral administration of OMZ capsules and rectal administration of 8 types of suppositories. The plasma concentration of OMZ (C$_{p}$)-time (t) curve after iv. administration fitted a two-compartment open model and the equation which best fitted the pharmacokinetics of OMZ was $C_{p}$ = 13.936 $e^{-8.78t}$+2.973 $e^{-0.716t}$. The bioavailabilities of OMZ in Witepsol H15 base (Supp-2) and PEG 4000 base (Supp-6) suppositories were 40.7% and 33.4%, respectively, which are higher(p<0.001) than 13% of oral administration of capsule. The avoidance fractions of the first-pass metabolism for Supp-2 and Supp-6 suppositiories were 31.8% and 23.4%, respectively, suggesting that the rectal application of OMZ may be a more adequate route of administration than oral one.

  • This case report aims to review complications that can occur during arthrocentesis and report an unusual complication observed in a 55-year-old man. The patient received arthrocentesis in an attempt to treat painful locking episodes of his right temporomandibular joint (TMJ). One hour after the operation, the patient experienced temporary facial paralysis in the area of the facial nerve and anesthesia of the lingual and alveolar inferior nerves. No persistent complications were detected during the postoperative follow-up. We suspected this complication occurred after anesthetic solution overflowed from a traumatic perforation in the joint capsule to the infratemporal area during the operation. To our knowledge, this complication has not been previously reported in the literature.

  • Genioplasy with osteotomy is a flexible and useful procedure. However, osteotomy can cause different types of morbidity. Chin augmentation with porous polyethylene ($Medpor^{(R)}$) has become popular in the recent years. Porous polyethylene ($Medpor^{(R)}$) is an excellent biomaterial for reconstructing facial deformities. $Medpor^{(R)}$ has a porous architecture, which prevents capsule formation and decreases the degree of foreign-body reaction. In addition, it can be easily cut with scissors and molded, and it also maintains its shape. We report here on a satisfactory case of chin augmentation with using porous polyethylene ($Medpor^{(R)}$).

  • Curcumin have various health-beneficial properties in numerous studies. However, its bioavailability is low due to its limited intestinal uptake and rapid metabolism. This study aimed to evaluate the pharmacokinetics of newly developed sub-micron particle curcumin with increased water dispersibility (Theracurmin(R) CR-033P). Plasma curcumin levels were measured at 0, 1, 2, 4, 8 h after Theracurmin(R) CR-033P intake using high-performance liquid chromatography. For analyzing pharmacokinetics of Theracurmin(R) CR-033P, eighteen healthy subjects were recruited and received Theracurmin(R) CR-033P at a single oral dose containing curcumin 30 mg. $C_{max}$ was 28.14 ng/ml, and the area under the curve for 8 h was estimated to be 104.36 ng/ml. Based on the area under the plasma concentration (AUC), the bioavailability of sub-micron particle curcumin was higher 22-, 35-, 28-fold than native curcumin in men, women, and all subjects, respectively. For comparing by formulation, seven healthy subjects were recruited and received two type of treatment: (1) existing dosage form 300 mg (contained curcumin 30 mg) ${\times}$ 3 capsule, (2) high dosage form 300 mg (contained curcumin 90 mg) ${\times}$ 1 capsule + placebo 300 mg ${\times}$ 2 capsule. In the cross-over study, there was no significant differences in $C_{max}$ and AUC of plasma curcumin. In conclusion, submicron particle curcumin with increased water dispersibility significantly improved its oral bioavailability and women absorbed curcumin more effectively than men. Different formulation of Theracurmin(R) CR-033P has shown equivalent to the reference in terms of pharmacokinetics.

  • Carduus marianus extract (formally called silymarin) have been used mainly as a medicament for hepatobiliary diseases. The major component of silymarin is silybin, which constitutes between 50 and 70% of the drug and is the major active component. Many experiments show the efficacy of silybin parenterally administerated. But, its bioavailability is low after oral administration due to its low solubility in water. (omitted)

  • Phlorotannins, the major constituent in brown algae, possess various biological activities; however, there is little information their toxicological effects. To assess the safety of phlorotannins, we investigated the acute oral toxicity of a high-purity phlorotannin preparation (PRT; total phlorotannin content 90%) in beagle dogs. Six beagle dogs (3 males, 3 females) were assigned randomly to three experimental groups. PRT was administered at oral doses of 250, 500, and 750 mg/kg by capsule. Vomiting by male and female beagles was observed with 500 and 750 mg/kg on the first day. In addition, one beagle given 750 mg/kg had soft stool and diarrhea on days 3 and 13. No deaths or abnormal clinical signs were observed during the experiment. All groups showed similar body weight gain and food consumption. Our acute toxicity study showed that PRT did not cause any toxicological effects in beagle dogs.

  • An Epidemiologic study was carried out on 77 TMD patients with degenerative joint disease who had visited the Orofacial Pain Clinic in Pusan National University Hospital. Al subjects were interviewed and examined clinically and radiologically using a standardized examination form. As related to gender and duration, subjective and objective sysmptoms in DJD patients were studied. The obtained results were as follows : 1. There were much more patients in the twenties or thirties, women and histories such as chronic duration and microtrauma. 2. Most patients responded positively more often to the questions of jaw function, unilateral chewing in habits, poot appetite and depression in behavioral response and shoulder pain in worsening prognosis 3. While the most common reasons for treatment were pain, noise, and limitation of opening, the associated symptoms such as headache, neckache, earache, jaw dysfunction, neck dysfunction, acute bite change and dizziness, ringing or fullness in the ears as secondary CNS excitatory effects were complained. 4. Opening the mouth in 25 to 40mm, soft end feel and deflective incisal pathway were seen and more tenderness to lateral or dorsal capsule of joint than intra or extra oral muscles were complained. 5. While there appeared no click, crepitus and single click in acute group, in chronic group, crepitus, single click and no click appeared in order of sequence. 6. Tomogram or bone scan revealed more bony changes than panorama and transcranial view.

  • In this study, 88 dental students were examined to evaluate the relationship between occlusal states and TM disorders for the epidemiologic study of TM disorders. The clinical evaluation were composed of mandibular movement, TMJ noise, occlusal states and muscle palpation. The following results were disclosed. 1. The frequencies of pain on mandibular movement were 3.4% on maximum opening, 1.13% on protrusion and no pain on laterotrusion. 2. The frequencies on TMJ sound were 21.6% in click, 1.13% in crepitus. 3. The frequency of tenderness on palpation was 12.5% on extra oral, intraoral and neck muscles, tenderness on palpation of TMJ capsule were reported 5 cases, and 4 of them were female. 4. The distribution of Angle's classification was found 79.5% in class I, 4.5% in clasII-div.1 and 15.9% in class III. There was no significant differences on TM disorders between Angles classifications. 5. There was no significant differences on TM disorders between the subjects of canine guided occlusion and group function occlusion, and also for the differences between the subjects of nonworking side interferences and no interferences on laterotrusion. 6. There was no significant differences on TM disorders between the subjects of anterior teeth trauma in C.C. and no anterior teeth trauma, but there were significant differences between the subjects of posterior protrusive contact and no posterior protrusive contact.

  • Chronic recurrent TMJ dislocation results in difficulty of mastication, speaking, and swallowing due to the limitation of the mandibular movement. Etiologic factors are considered as the looseness of the capsule and ligaments, the decrease of the articular eminence, condylar morphologic change, muscular disharmony near by TMJ, and the decrease of the vertical length of the mandibular ramus. Treatment approach has been suggested that surgical methods are selected for the correction of the etiologic factors when conservative treatments are not effective. Many surgical methods have been reported such as eminectomy, eminence augmentation, condylotomy, and zygomatic arch down fracture technique. We performed the eminence augmentation through interpositional bone graft in chronic recurrent TMJ dislocation. This method leads to favorable postoperative result without recurrence and complication, so we report the case with related references.

  • Synovial condromatosis of the temporomandibular joint (TMJ) is characterized by the presence of loose bodies (joint mices). It can be confused with temporomandibular disorder clinically, and be with chondrosarcoma histologically. The purpose of this clinical report was to review the clinical, radiological, arthroscopic findings, histological feature and the results of surgical treatment of TMJ synovial chondromatosis. Four patients presented with pain of TMJ and limited mouth opening. The dynamic magnetic resonance imaging (MRI) disclosed a characteristic morphologic changes and displacement of the meniscus with limited translation of the condyle head. Bone scans showed progressive resorptive changes with hot-uptake of the radioisotope. The synovial loose bodies in the joint spaces were removed and sent to pathology for diagnosis as the synovial chondromatosis. The follow-up examination with computed tomography (CT) and MRI revealed no evidence of recurrence and good in function until postoperative 18 months. Diagnostically, the distension of the lateral capsule and fluid findings in the joint on the MRI are very suggestive tool for this synovial chondromatosis, but they are not always detected on the preoperative MRI. Arthroscopic approaches are very useful to inspect the joint spaces and to remove the loose bodies without interruption of the whole synovial membranes.
