The cysteine proteases of Paragonimus westermani metacercariae are involved in metacercarial excystment, host immune modulation, and possibly in tissue penetration. In order to clarify the origin of the enzymes, 28 and 27 kDa cysteine proteases in metacercarial excretory-secretory products were purified through the FPLC system using Mono Q column chromatography. The polyclonal antibodies to the enzymes were produced in BALB/c mice. Immunolocalization studies revealed that both cysteine proteases were distributed at the linings of excretory bladder and excretory concretions of the metacercariae. It was suggested that the excretory epithelium of P. westermani undertake the secretory function of metacercarial cysteine proteases, in addition to its role as a route for eliminating waste products.

Recent studies suggest that alterations of the immune-inflammatory system contribute to the pathogenesis of Alzheimer's disease (AD), Parkinson's disease (PD) and Amyotrophic Lateral Sclerosis (ALS). Neuroinflammatory response initiated by innate immune mechanism that self-attack on neurons, known as "autotoxicity" could be an initial key mechanism of chronic neurodegenerative diseases. Numerous experimental and pathological evidences showing upregulated inflammatory cytokines and chemokines, and the activation of complement cascade and accumulation of activated microglia in damaged regions support the important role of immune-inflammatory mechanism in the pathogenesis of neurodegenerative diseases. Epidemiological studies on the non-steroidal anti-inflammatory drugs (NSAIDs), coupled with results from animal model of AD, PD and ALS, have prompted the studies to determine if immune-inflammatory modifying agents or molecules could be a new therapeutic paradigm of neurodegenerative diseases. Molecules inhibiting proinflammatory cytokines and chemokines released from microglia, agents that inhibit activation of microglia, COX2 and complement system are now considered as a good candidate of immune-inflammatory modulating treatment. By better understanding inflammatory and immunoregulatory processes, it should be possible to develop anti-inflammatory approach that may not completely cure AD, PD, and ALS but will likely help slow the progression or delay the onset of these devastating diseases.

Cervical incompetence is one of the main contributors to repeated pregnancy loss and preterm delivery. Typically it results in progressive cervical dilatation, leading to a painless second or early third trimester abortion. Emergency cerclage can be used in the setting of advanced cervical incompetence, even when fetal membranes bulge through the dilated cervix. To facilitate the procedure, various techniques have been developed to replace the fetal membranes into the uterine cavity. We performed six successful cases of emergency cerclage combined with amnioreduction in advanced incompetent internal os of cervix (IIOC). Interval from emergency cerclage to delivery was 8.1 +/- 2.4 weeks (range 4-10 weeks) and we delivered viable fetuses in all but one. Hereby we report our experiences with a brief review of literature.

By finding the documents of Korean physical anthropology in one place easily, everyone can use them fruitfully. We developed internet site to search them, which published from early 20th century to present days. We also analyzed documents of physical anthropology and databased the tables which is considered to be kernel of results. The advantage of this internet site is followings. We classified the documents of physical anthropology by body regions and we also classified them in detail to reach them easily. The documents are also divided into materials and its methods to search conveniently. Everyone can search a data by classification and also by using a keyword they can find document or data. There are 3 steps to search. First step is searching the title of document and author, second step is searching the name of table including the first step and the last step is searching items in table. If they don't know the contents they can search data by index. We added some pictures and explanations to restore the document or table, which are difficult and hard to understand the point. By these additions, we could understand them briefly. We could quote from past data and also we could easily compare previous data with ours by using this search engine.

To evaluate the CT and MR findings of cerebral paragonimiasis (PW) and to assess the diagnostic value of the specific antibody test by enzyme-linked immunosorbent assay (ELISA) for PW, 55 CT scans and 13 MR images of 57 patients with cerebral PW were reviewed retrospectively, and correlated with the serum/CSF antibody levels. We divided the into three groups, early active(n=21), chronic(n=32), and combined stage (n=4), on the basis of CT/MR findings. In the group of early active stage the most common and characteristic findings was multiple, conglomerated, ring-like enhancing lesions in the unilateral cerebral hemisphere, which was seen in 52% on CT and 44% on MR. Other non-specific findings included a solitary ring-like or irregular enhancing lesions, ill-defined low density lesions without enhancement, localized hemorrhage with or without enhancing lesions. In the group of chronic stage there were multiple calcifications of various shapes, most commonly 1-2cm sized round shape, and associated encephalomalacia. MR was superior to CT in detecting hemorrhage and in characterizing the central contents of ring-shaped calcifications, while it was inferior to CT in identifying small calcifications. Antibody levels of serum and CSF were positive in 86% and 82% in early active group, and in 48% and 31% in chronic sgage respectively. The positive rate was significantly different between the two groups (P=0.001). CT/MR findings were characteristic in only approximately half the cases in early active cerebral PW which can be cured by traziquantel therapy. Therefore, antibody test by ELISA is recommended as a complementary tool, particularly in patients with non-specific imaging findings.

BACKGROUND: Over activation of the DNA repairing enzyme, poly (ADP-ribose) polymerase (PARP) in response to oxidative damage of DNA appears to play a role in cellular death in neurodegenerative diseases. Previous data suggested that PARP immunoreactivity (IR) was increased in the white and gray matter in spinal cord of the sporadic amyotrophic lateral sclerosis (sALS), predominantly in cells with astroglial morphology. METHODS: In the present study, we evaluated whether the PARP expression was present widespread in various regions of brain tissue including the motor cortex, parietal cortex and cerebellum. RESULTS: By western blot, PARP-IR in motor cortex from sALS patients, compared to the same region from age-matched normal controls, was also significantly increased (p=0.006). Importantly, PARP-IR was also increased in the parietal cortex, and cerebellum of sALS patients compared to the controls, in regions that are usually clinically unaffected in ALS (p=0.043, p=0.035, respectively). In addition, increased PARP expression in ALS was more prominent compared to Alzheimer's brain. Immunohistochemistry revealed that PARP staining was more significant in the cortical neurons and in the subcortical white matter glial cells from sALS patients compared to normal controls and Alzheimer's disease. CONCLUSIONS: The data demonstrate that increase in PARP-IR is not limited only to the vulnerable motor cortex. Furthermore, PARP-IR is present in both cortical neuronal and subcortical glial cells. The data suggest that widespread cellular stress on neuronal and glial cells is present in the brain of sporadic ALS patients.

PURPOSE: This study aimed to identify the true extent of non-responsiveness in full-term infants born from HBsAg-negative or HBsAg-positive mothers and vaccinated against hepatitis B virus (HBV) at 0, 1, and 6 months of age and to evaluate the effect of revaccination among non-responders. METHODS: The study included 716 full-term infants born in 2004-2007. Of 716, 662 infants (A group) were born to HBsAg- negative mothers and 54 infants (B group: 50, except HBsAg-positive infants) were born to HBsAg-positive mothers. All infants were administered DNA recombinant vaccines at 0, 1, and 6 months of age. B group infants received hepatitis B immunoglobulin at birth. Anti-HBs titers were tested at 7-12 and 9-15 months in A and B groups, respectively. Three revaccination doses were administered to non-responders whose anti-HBs titers were under 10 mIU/ml; revaccinated infants were retested at 1-3 months after last vaccination. The association between HBeAg seropositivity of mother and the failure of HBV immunoprophylaxis was evaluated. RESULTS: The seroconversion rates after primary hepatitis B vaccination were higher in A group (94.1%) than in B group (78%, P<0.001). The seroconversion rates were high in revaccinated infants (A group non-responders: 96.9%, B group non- responders: 87.5%). The failure of HBV immunoprophylaxis was significantly associated with maternal HBeAg seropositivity (P<0.001). CONCLUSION: The seroconversion rates after primary hepatitis B vaccination were low in B group infants. Revaccination of non-responders in B group was very effective. Therefore, anti-HBs testing and revaccination of B group is very important. Revaccination of non-responders in A group was also very effective. Thus, testing the immune status of infants born to HBsAg-negative mothers even after primary hepatitis B vaccination should be considered. However, to realize this, further studies on the cost-effectiveness of anti-HBs testing in healthy full-term infants are necessary.

The authors report a case of far lateral disc herniation at L4-5 found one year after percutaneous laser lumbar discectomy. The patient was found to be suffering from new-onset right lumbar radiculopathy 6 months after his first operation, and post operative lumbar MRI confirmed a far lateral extraforaminal disc herniation at L4-5, with compression of the nerve. This corresponded to the nucleotomy site of the probe. The patient underwent surgery employng the combined paraspinal intertransverse and interlaminar approach, and his symptoms were relieved. This case emphasizes the importance of removing nuclear material, and shows that remaining material can herniate through a percutaneous discectomy window.
