The intraction between cimetidine and rifampicin was studied pharmacokinetically in normal human subjects. The serum level and the area under the serum concentration curve(AUC) of rifampicin administrated orally were elevated significantly by cimetidine. Volume of distribution, total clearance and elimination rate constant of rifampicin were reduced significanyly by cimetidine. Biological half-life of rifampicin was prolonged significantly by cimetidine. The mechanism of this results is probably related to the inhibition of rifampicin metabolism(deacetyl form) or reduction of blood flow in the liver. It is desirable that dosage regimen of rifampicin shoud be adjusted when combined with cimetidine in clinical pharmacy practice.

The most common form of autosomal recessive hereditary spastic paraplegia (HSP) is caused by mutations in SPG11/KIAA1840 gene, which encodes for spatacsin. The clinical presentation of SPG11 is characterized by cognitive impairment, peripheral neuropathy and a thin corpus callosum in brain magnetic resonance imaging. We identified a novel homozygous nonsense mutation (c.6082C>T [p.Q2028]) in exon 32 of SPG11 in Korean siblings. Our findings suggest that this novel homozygous mutation in SPG11 is associated with HSP and with dysgenesis of the corpus callosum.

The purpose of this study was to develop discriminant analysis models for predicting cervical normal/dysplasia case diagnoses using cytometric features derived from the digital image analysis of cell monolayers. The database consisted of 19 cases diagnosed either as normal (n=5), moderate dysplasia (n=7), severe dysplasia (n=7) on monolayer preparations. We studied the nuclear and cytoplasmic characteristics of cells in the normal, moderate dysplasia and severe dysplasia on cervical samples. The morphometric parameters selected for the analysis were nuclear/cytoplasmic ratio and the nuclear variations measured by image analysis on normal and precancerous lesions of cervical smears; several shape factors; area; perimeter; maximal, minimal and equivalent circle diameters. The results showed that the dysplasia samples exhibited changes in both cellular and nuclear form and size but lacked substantial differences in the tumor grades. The coefficient of nuclear variation is as follows to normal cell $21.8{\pm}3.2%$, moderate dysplasia $33.5{\pm}6.1%$, severe dysplasia $27.7{\pm}5.8$ of cervical smears.

Mucopolysaccharidosis III (MPS III, Sanfilippo syndrome) is a rare autosomal recessive disease caused by a deficiency of one of four enzymes involved in the degradation of glycosaminoglycan (GAG). The resultant cellular accumulation of GAG causes various clinical manifestations. MPS III is divided into four subtypes depending on the deficient enzyme. All the subtypes show similar clinical features and are characterized by progressive degeneration of the central nervous system. A number of genetic and biochemical diagnostic methods have been developed. However, there is no effective therapy available for any form of MPS III, with treatment currently limited to clinical management of neurological symptoms. Main purpose of the treatment for MPS III is to prevent neurologic deterioration. Because conventional intravenous enzyme replacement therapy (ERT) has a limitation due to inability to cross the blood-brain barrier, several innovative therapeutic approaches for MPS III are being developed. This review covers the currently developing new therapeutic options for MPS III including high dose ERT, substrate reduction therapy, intrathecal or intraventricular ERT, fusion protein delivery using bioengineering technology, and gene therapy.

Tibialis anterior (TA) muscle originates from the lateral surface of tibia and its tendon attaches to the medial cuneiform and base of the first metatarsal. The TA muscle is responsible for both dorsiflexion and inversion of the foot. We present a case of bilateral TA muscle variations that diverge slightly from the current classification systems of this muscle. Recognizing variations such as these may be important for anatomists, surgeons, podiatrists, and physicians. Following routine dissection, an accessory tendon of the TA muscle was found on both sides. Accessory tendons of the extensor hallucis longus and extensor hallucis brevis joined to form a common tendon on both sides. We believe that this unique case will help further the classification systems for the tendons of the TA and also be informative for clinical anatomists as well as physicians treating patients with pathology in this region.

Thalassemias are considered important health issues throughout Iraq, involving its Kurdistan region. This disorder, particularly its major form, needs lifelong regular transfusions. But this form of medical care is associated with various complications including red cell alloimmunization and autoimmunization. This study determined the frequency and associations of alloimmunization among multi-transfused patients with β-thalassemia major. The subjects were 204 patients who were registered at a thalassemia care center in Sulaymaniyah-Iraqi Kurdistan. The patients' records were analyzed, their red cells were phenotyped for ABO/RhD antigens using the gel card method, and irregular antibody screening/identification was performed using the standard tube method. Alloantibodies were detected in 5.8% of the patients, while DAT was positive in 4% of the patients, which indicated autoantibodies. The identified alloantibodies were anti-E (2.4%), anti-C (1.4%), anti-e (1%), and anti-K (1%). A patient's age at the start of transfusion (>2 years) (P=0.042) and a positive history of transfusion reactions (P=0.003) were correlated with a significantly higher rate of alloantibody formation. From the results of our study, we conclude that measures to decrease the development of alloantibodies may incorporate matching for Rhesus and Kell systems and early induction of blood transfusions.

Ideal autogenous or allogenic bone graft materials should provide 1) stabilization of blood clot, 2) scaffolds for cellular proliferation and differentiation, 3) release of osteogenic growth factors, 4) appropriate resorption profile for remodeling of new bone. Teeth, especially dentin, mostly contain hydroxyapatite and type I collagen which are similar to bone, and could be valuable graft material. Clinically teeth are used as calcined or demineralized forms. Demineralized form of dentin can be more effective as a graft material. But a conventional decalcification method takes time and long treatment time may give negative effects to various osteogenic proteins in dentin. Author used a new clinical method to prepare autogenous teeth, which could be grafted into the removal defects immediately after extraction using vacuum ultrasonic system. The process could be finished within two hours regardless of the form (powder, chip or block). Teeth were processed to graft materials in block, chip, or powder types immediately after extraction. It took 120 minutes to prepare block types and 40 minutes to prepare powder. Clinical cases did not show any adverse response and the healing was favorable. Rapid preparation of autogenous teeth with the vacuum ultrasonic system could make the immediate one-day extraction and graft possible.

Candida spp. are yeast form fungi, which cause an opportunistic infections in a immune suppressed patients however it is a normal flora of the respiratory system, the gastrointestinal system, and the urogenital system of healthy person. It is investigated that the distribution of Candida spp. cause an oral disease from oral cavity of healthy people and also identified Candia dubliniensis. Distribution and identification of the yeast form fungi in oral cavities of healthy people was investigated by an automatic identifier, VITEK2 system. We found 21 strains of Candida albicans, 3 strains of Candida famata, one strain of Candida tropicalis, Candida haemulonii, Candida krusei, and Candida dubliniensis. In addition, one strain of Cryptococcus spp., Saccharomyces spp., and two unknown strains were isolated. Candida dubliniensis which forms a mass by more than 2 chlamydospores was isolated from a healthy person for the first time. Candida dubliniensis was not grown at $42^{\circ}C$ whereas Candida albicans was grown well. It is known that Candida dubliniencis was isolated in AIDS while it is found in healthy people from this study, which will be helpful to investigate the distribution of Candida spp.

Osseointegrated dental implants have now become and accepted form of treatment for patients with a fully or partially missing dentition. The purpose of this study was to evaluate the performance of AVANA implant-Korea. A total of 323 AVANA implants were placed at 9 centers in the edentulous and partially edentulous jaws of 88 consecutive patients ranging in age form 18 to 79 years. So we get the clinical results. 1. Both patients (94.4%) & doctors (94%) were satisfied with the results, in patient's aspect 'most satisfaction' case were more common(52%) 2. The length of fixture which was frequently used was 13mm (168/319,44.5%) followed by 15mm and 10mm, and 3.75mm width implant (239/319,74.9%) was the most popularly used. 3. Mandibutar posterior was the most common installation site (140/317.43%) 4. A mean implant survival rate was 96.2%. That showed little difference which reported other paper. Cause of failure consisted of inflammation $ infection-36%, fall of osseointegration-18%, paln during masticatory function-9%. improper prosthetic function $ procedure-9%. 5. The most popularly used types of abutment was the UCLA abutment(168/305,55.5%)
