Malaria in Korea

Malaria was steadily decreasing in Korea except in certain counties of the mountainous and hilly areas, in the 1960s. Judging from the present epidemiological, social and economic conditions, it can be said with confidence that malaria with "unstable" characteristic in the Republic of Korea has already been disappeared. No doubt, the causes of the disappearance of malaria are complex. Certainly improved living conditions and life style; better medical and educational facilities in the wake of a rapid economic development could all have some role. On the other hand, the disappearance of malaria without large scale control operations could be ascribed to the two main factors: one is malaria case detection and simultaneous drug therapy available through the nation-wide passive case detection network during the 1960s and the other is rapidly improved farming practices begun in 1970s, which resulted in the use of a huge quantity of pesticides and other chemicals for agriculture, which, in turn, might affect local anopheline vectors which were originally not effective ones any way.     

Interaction of trichohyalin with intermediate filaments: three immunologically defined stages of trichohyalin maturation.

"Trichohyalin" is a 220-kD protein found in trichohyalin granules that are present as major differentiation products in the medulla and inner root sheath cells of human hair follicles. It was unclear whether this protein served as an intermediate filament precursor in the inner root sheath or as an intermediate-filament-associated (matrix) protein. We have produced a panel of monoclonal antibodies (AE15-17) to this protein and used them to trace its fate during inner root sheath differentiation. These studies have allowed us to define three immunologically distinct forms of this trichohyalin protein. They are 1) the AE15-positive form, which is found throughout all trichohyalin granules; 2) the AE16-positive form, which is localized as discrete punctae on the surface of trichohyalin granules; and 3) the AE17-positive, intermediate-filament-bound form, which associates with the inner root sheath filaments with a regular, 400-nm periodicity. From these results we suggest that the 220-kD trichohyalin protein is an intermediate-filament-associated protein that may play a role in the lateral aggregation, precise alignment, and stabilization of inner root sheath filament bundles.     

Eruption effects of microdontia--a case report

A patient presented at the Department of Orthodontics, Medunsa Dental Hospital, complaining of "crooked teeth". On clinical examination it was evident that several teeth were unerupted. The absence of a normal eruption pattern of certain teeth as well as delayed eruption of others, resulted in a malocclusion.     

Tumor-induced osteomalacia and rickets

Tumor-induced osteomalacia is a clinicopathological entity in which vitamin D-resistant osteomalacia or rickets occurs in association with a tumor. A total of 72 cases (three current, 69 from review of literature) has been reported to date. Men and women are equally affected. The majority are adults over 30 years old who exhibit progressive lower leg and back pain. Forty bone and 31 soft-tissue tumors were responsible for this syndrome; two-thirds occurred in the extremities. Chemical findings are typical: low serum phosphorus, normal serum calcium, and elevated alkaline phosphatase. Serum levels of 1,25-dihydroxyvitamin D were low or undetectable. Histologically, more than a third were classified as vascular tumors, and half of these cases were hemangiopericytomas that were distributed equally between bone and soft tissues. Other common diagnoses included nonossifying fibromas, "mesenchymal" and giant-cell tumor variants. Features common to all tumors were prominent vascularity, and giant and primitive stromal cells. Only 10 were histologically malignant. Ultrastructural studies have not shown any secretory granules suggestive of a hormone-secreting tumor. It is clear, however, that the tumor is responsible for the osteomalacia because the complete removal generally results in a dramatic reversal of all symptoms and signs.     

Results of animal experiments using an undulation pump total artificial heart: analysis of 10 day and 19 day survival

An undulation pump is a special rotary blood pump in which rotation of a brushless DC motor is transformed to an undulating motion by a disc in the pump housing attached by means of a special link mechanism. In the blood pump, a closed line between the disc and housing moves from the inlet to the outlet by this undulating disc motion, which sucks and pushes the blood from the inlet to the outlet. Because the same phenomena occurs at both sides of the disc, a continuous flow is obtained when the motor rotational speed is constant. The pump flow pattern can be easily changed from continuous flow to pulsatile flow by controlling the motor drive current pattern. A seal membrane made of segmented polyurethane protects the blood from invading the link mechanism as well as the motor. UPTAH is fabricated with two undulation pumps and two brushless DC motors. Its size is 75 mm in diameter and 80 mm long, and it has one of the great advantage of no compliance chamber required in the system. UPTAHs were implanted under cardiopulmonary bypass (CPB) into the chest cavities of 16 goats, each weighing between 41 and 72 kg. No anticoagulant and antiplatelet agent was used after the surgery. The left atrial pressure was automatically controlled to prevent its elevation and sucking of the atrial wall into the atrial cuff. The following results were obtained: (1) UPTAHs fit well into all the goats; (2) the longest survival was 19.8 days, the cause of death was bleeding from the aortic anastomosis; (3) No thrombus was observed in the blood pump despite no anticoagulant use. Hemolysis depended upon the length of CPB during surgery. When CPB time was within 2 hours, hemolysis level returned to baseline within a few days of the surgery. UPTAH is a promising implantable TAH, because of its small size and easy controllability.     

Increased mast cell density during the infection with velogenic Newcastle disease virus in chickens

In addition to their well-characterized role in allergic inflammation, recent data confirm that mast cells play a more extensive role in a variety of viral infections. The contribution of mast cells to Newcastle disease pathogenesis has not been investigated. We evaluated mast cell activity after Newcastle disease virus (NDV) infection in specific pathogen free chickens using cytochemical and immunocytochemical analyses. The results were as follows. Severe tissue damage was observed in the proventriculus, duodenum, jejunum and caecal tonsil, and NDV antigens were detected and presented extensively in these tissues. Second, in the NDV-infected group, the mast cell population was increased markedly in the proventriculus, duodenum, jejunum and caecal tonsil at 24, 48, 72 and 96 h after infection (P<0.01). However, very few mast cells were observed in those same tissues in the control. More intriguingly, the greatest number of mast cells was found in the proventriculus, which also showed the greatest level of NDV antigens. Third, the content of tryptase was significantly higher (P<0.01) in the NDV-infected group compared with the control from 24 to 96 h post infection). Furthermore, as an important protease released by mast cells, tryptase had a positive correlation with mast cell distribution. These data indicated that mast cells were involved in the response to NDV. Our results also suggested that the broad range of mast cell mediators might have a role in the pathology of Newcastle disease.     

Effect of anti-inflammatory medication on monocyte response to titanium particles

Cytokines produced by macrophages in the periprosthetic membranes surrounding joint replacements have been implicated as causal agents in osteolysis and prosthetic loosening. The present study characterizes the response of human peripheral blood monocytes to titanium particles. Monocytes were obtained from donated blood and were cultured in the presence of different-sized titanium particles. Exposure to titanium-aluminum-vanadium particles significantly changed the release of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and interleukin-1 (IL-1), whereas there was no significant effect on the release of prostaglandin E(2) (PGE(2)). When monocytes were cultured with particles, the titanium alloy particles induced significantly more release of TNF-alpha and less IL-1 secretion. Ciprofloxacin inhibited production of TNF-alpha, IL-6, IL-1, and PGE(2) in human monocytes exposed to titanium particles. In contrast to ciprofloxacin, indomethacin was not a potent inhibitor of TNF-alpha production but potentiated IL-6 production in titanium-stimulated monocytes. Indomethacin had no effect on the production of IL-1 and was a potent inhibitor of PGE(2) production in titanium-stimulated monocytes. Pentoxifylline had an inhibitor effect on TNF-alpha production in titanium-stimulated monocytes. Pentoxifylline potentiated IL-6 and IL-1 production in monocytes exposed to titanium particles and had a biphasic effect on the PGE(2) production. The results of this study support our hypothesis that human monocytes release bone resorption mediators after in vitro exposure to TiAlV alloy particles. The results also demonstrate the differences of bone-resorbing mediators in response to different wear particle size. The pharmacologic agents (ciprofloxacin, pentoxifylline, and indomethacin) that can modulate the release of bone resorbing mediators such as PGE(2), TNF-alpha, IL-1, and IL-6 release from human monocytes. The results help to elucidate the differences in cellular response to wear particles but may not be directly transposed to the human situation.
