Salicornia herbacea is an annual herb growing in salt marshes and on muddy seashores. Salicornia herbacea has been used as a fork medicine as well as a seasoned vegetable. In fork medicine, Salicornia herbacea has been used to treat a variety of diseases such as constipation, obesity, diabetes, asthma, arthritis and cancer. However, the biological mechanisms for these activities have not been characterized, nor the active components. The immunomodulatory activity of Salicornia herbacea components were studied in the present study. The components of Salicornia herbacea were prepared from the whole plant by passage through a fine screen, and then dialyzed against PBS overnight. Immunomodulatory activities of the Salicornia herbacea components were examined on a mouse macrophage cell line, RAW 264.7 cells. The Salicornia herbacea components were shown to stimulate cytokine production, nitric oxide release, and expression of surface molecules in a dose dependent manner. The Salicornia herbacea components also induced further differentiation of slightly adherent RAW 264.7 cell into strongly adherent macrophages. These results indicate that Salicornia herbacea contains immunomodulator(s) that induces activation of macrophages.

The time honoured tuning fork at present widely available for examining vibration sensation is brought about the problem of great interobserver variation. To resolve t his problem, author developed a divice using electric magnet that stimulates constantly tuning fork. The perception time of vibration from tunung fork by this device was tested on the index finger of dominant hand of twenty eight subjects. It was 12.44 seconds on average and ranged from 9.47 to 17.25. Coefficient of variation of it was 16.89 percent. Correlation coefficient between test and retest after 30 minutes was 0.957(p<0.01). This device is portable. Test procedure in non-invasive, non-aversive and simple, can be performed within one minute, and does not require the skilled technician. It is felt that this device testing vibration perception time is suitable as screening tool for early detection of occupational peripheral neuropathy.

Gekko has been used for several diseases including cancer in Oriental medicine and fork herbalogy. Nevertheless, its origin as herbal medicine and its efficacy and mechanism as anti-tumor drug have not yet been thoroughly reported in Korea. This study aimed to investigate anti-tumor effect of Gekko through selected articles from cqvip database in China. In vitro and In vivo, Gekko could obviously inhibit tumor growth, induce tumor cells apoptosis, reduce micro-vessel density in tumor tissue through down regulating VEGF & bFGF protein expression, promote cytotoxicity of lymphocyte. Gekko could improve survival rate, relive clinical symptoms, improve quality of life, and relieve anti-tumor treatment reaction, suggesting that Gekko might be a effective anti-tumor drug.

Korean folk medicine 'Jil-Kyung-Ee' has been used to cure female disease, acute gastritis, edema, abdominal pain and pleurisy. The botanical origin of the crude drug has not been confirmed pharmocognostically. To clarify the botanical origin of 'Jil-Kyung-Ee', the morphological and anatomical characteristics of the leaves and roots of Plantago species growing in Korea, i.e. P. asiatica L., P. camtschatica Cham., P. depressa Willd., P. lanceolata L., P. major L. var. japonica (Fr. et Sav.) Miyabe were compared. As a result, it was determined that 'Jil-Kyung-Ee' was the whole plant body of Plantago asiatica and Plantago camtschatica.

At the eukaryotic replication fork, discontinuous synthesis of lagging strand DNA gives rise to Okazaki fragments carrying ribonucleotides derived from the primer RNA at their 5' ends. Efficient removal of these ribonucleotides is vital for maintaining genome integrity. In this report we show that the endonucleases Dna2 and Fen1 act sequentially to facilitate the complete removal of the primer RNA.(omitted)

Moyamoya disease is defined as the development of collateral pathways, associated with bilateral chronic progressive stenosis of the carotid fork. Persistent trigeminal artery is the vessel most frequently observed to persist into adult life among persistent carotid-basilar and carotid-vertebral anastomotic vessels. The authors present a man who had a sudden, severe headache and brain CT showed subarachnoid hemorrhage in left interpeduncular and prepontine cistern. Four-vessel angiogram revealed moyamoya disease associated with aneurysm arising from the junction of persistent trigeminal artery aneurysm and basilar artery. As a treatment, coil embolization was tried but it was failed because of anatomical difficulty of aneurysm. The aneurysm was successfully treated with clipping surgery 10 days later. To our knowledge, this is the first case being reported.

This paper aims to probe the cell differentiation and gene activity in early Oogenesis from Dendrolimus spectabilis Butler by transmission electron microscope. The 8 cystocytes are formed by mitosis of the Oogonia, and differentiated to the 1 Oocyte and 7 nurse cells. The oocyte and nurse cells are connected by ring canals, through which the cytoplasmic organelles such as mitochondria, free ribosomes, and electron dense granular materials are passed from nurse cells to o cyte. Many replication fork in the cystocyte nuclei and 2 transcriptional units of $2.7{\mu}m\;and\;0.36{\mu}m\;or\;0.5{\mu}m$ in the nurse cells are observed by the chromatin spreading technique. It is possible that transcriptional units are passed from nurse cells to Oocyte.

Surface plasmon resonance has been used for a biospecific interaction analysis between two macromolecules in real time. Determination of an antibody that is capable of specifically interacting with the native form of antigen is very useful for many biological and medical applications. Twenty monoclonal antibodies against the $\alpha$ subunit of E. coli DNA polymerase III were screened for specifically recognizing the native form of protein using surface plasmon resonance. Only four monoclonal antibodies among them specifically recognized the native $\alpha$ protein, although all of the antibodies were able to specifically interact with the denatured $\alpha$ subunit. These antibodies failed to interfere with the interaction between the $\tau$ and $\alpha$ subunits that were required for dimerization of the two polymerases at the DNA replication fork. This real-time analysis using surface plasmon resonance provides an easy method to screen antibodies that are capable of binding to the native form of the antigen molecule and determine the biological interaction between the two molecules.

A case of Strongyloides stercoralis infection was experienced in a 73-year old Korean female patient, was hospitalized with relapse of cholecystitis. The patient developed cough and dyspnea 17 days after the admission. On the 27th hospitalized day, diarrhoea, nausea, vomiting and abdominal pain started. A number of parasitic larvae were incubated at $25^{\circ}C$ for 2 days. Typical fork tailed filariform larvae of S. stercoralis (Bavay, 1876) Stiles and Hassall, 1902, were identified after cultivation. There was no improvement of diarrhoea after the medication with mebendasole. After the administration of thiabendazole, however, diarrhoea was stopped. On the 6th day of medication, S. stercoralis larvae was no more detected, and thereafter no larva was observed by repeated stool examinations upto 2 months after chemotherapy. The patient had the history of administration of steroid for articular rheumatism. Therfore this ,case seems to be a hyperinfection of S. stercoralis due to an autoinfection and to be the first report on the hyperinfected strongyloidiasis in Korea. Related literature was briefly reviewed.

As part of our screening of anticariogenic agents from medicinal plants, the ethanol extracts of 10 herbs widely used in the fork medicine were tested for the antimicrobial activity against a cariogenic bacterium Streptococcus sobrinus. The ethanol extracts of Dryopteris crassirhizoma showed antimicrobial activities against S. sobrinus. These results suggested that the extracts of Dryopteris crassirhizoma could be the potential source of antimicrobial agent against S. sobrinus.
