PURPOSE: To verify the expression of mouse homologue of glucosamine-6-phosphate deaminase (GNPDA) in mouse epididymis. MATERIALS AND METHODS: GNPDA expression was examined in mouse epididymis using the polyclonal antibody raised against a synthetic oligopeptide of N-terminus of mouse homologue of GNPDA. RESULTS: In Western blot, immunoreactive band of Mr. 33 kDa was detected in the cauda epididymal extracts. In immunostaining, positive signal was found in the cytoplasm and stereocillia of epithelial cells of cauda epididymal tubule, and interstitial cells of adult epididymis. CONCLUSION: Expression of GNPDA in epididymis suggests that it possibly involved in absorption and intracellular digestion of luminal contents, and the remodeling of epithelia in mouse epididymis.

One hundred and fifty two open wounds of extremities including open fractures were treated at the Kyoungpook Nstional Univ. Hospital from March 1977 to August 1977. Of 152 open wounds there were 32 cases (21.5%) of wound infection even though the initial wound culture revealed bacterial growth in 44 cases(28.9%). However, there were only 10 cases of infection among the cases with positive bacterial growth in the original culture and the same organisms were found in the 6 cases between the initial wound culture and post infection culture. Sensitivity studies of the organisms, the Cephalosqorines appeared to be most effective as a prophylactic antibiotics. It was sensitive to all gram positive organisms and majority of gram negative organisms including Escherichia coli. In bacterial culture and sensitivity studies of the 82 open fracture wounds 18 of them showed gram positive and gramnegative bacteria. The prominant organism were Staphylococcus, Escherichia coli, Streptococcus and Pseudomonas. The infection rate was lower in the cases whar the wound was managed within six hours from the time of injury than after six hours.

Gas producing infection accompanied by evidence of subcutaneous gas usually are diagnosed as clostridial gas gangrene. The occurrence of nonclostridial gas producing infection is thought to be relatively rare. Two cases of nonclostridial gas producing infection simulating clostridial gas gangrene in diabetes occurred. Gram stains of pus at the time of admission can isolate the E-coli and streptococcus, and can distinguish these two entities. Chief conplaints were swelling, pain and tenderness of right lower extremity by infection. Multiple incisions to free the tissues of gas and pus and the administration of antibiotics are the treatment of choice.

PURPOSE: To verify the expression of the mouse homolog of glucosamine-6-phosphate deaminase (GNPDA) in the testis and reproductive organs. MATERIALS AND METHODS: Expression of GNPDA was examined using a polyclonal antibody raised against a synthetic oliogopeptide of the N-terminus of the protein. RESULTS: In Western blots, an immunoreactive band of Mr 35 kDa was detected in the testis, ovary, and uterus extracts. Expression of GNPDA was greater in the adult than in the immature testis. With immunostaining, a positive signal was found in the cytoplasm of interstitial, Sertoli, and germ cells of adult testis. In the ovary, positive staining was found in the interstitial and luteal cells. Conclusion: The expression of GNPDA in many reproductive tissues suggests that the enzyme plays a housekeeping role in cell physiology and in the differentiation of the seminiferous tubules.

BACKGROUND: Monocytes/macrophages play a central role in determining the host response during Gram-negative infection through secretion of a variety of mediators after stimulation of LPS. Even though cytokine production has been shown to play an important role in host defense during sepsis cytokine release may also lead to tissue injury. Thus, regulation of macrophage response to LPS is critical for host survival during Gram-neg-alive sepsis. In animals exposed to nonlethal doses of endotoxin a characteristic hyporesponsiveness to subsequent administration of endotoxin has been observed. This phenomenon was knowm as 'LPS tolerance'. However, little information is availavble regarding the underlying mechanism of U)S tolerance. METHOD: Peripheral blood monocyte(PBMC) was isolated from peripheral blood of normal volunteers by adhesion purification method. To evaluate conditions to obtain LPS tolerance. preculture was carried out with LPS at 10ng/ml for 24 hours. For stimulation culture plates were washed two times and were stimulated with LPS at 1ng/ml for 4, 6 and 26 hours. To assess the underlying mechanisms of LPS tolerance, autologous serum, PMA, anti-CD14 Ab, Indomethacin or PGF2 were added to preculture solution respectively. Cytokine concentrations in culture supernatants were measured using ELISA for TNF-α and IL-8 and mRNA of TNF-α and IL-8 were determined by Northern blot analysis. RESULTS: The exposure of PBMC to low dose of LPS suppressed the cytokine production and mRNA expression of TNF-α, but not IL-8. Anti-CDl4 Ab partially recovered production of TNF-α which was suppressed by preculture with low dose LPS. The preculture with PMA induces US tolerance, as preculture with low dose LPS. CONCLUSION: LPS tolerance to TNF-α is regulated pretranslationally and is influenced by protein kinase C pathway and CD14.

OBJECTIVES: In order to devise the combination module transmitting bio signal and signal data remotely, as defect of wirewireless combination module was complemented by designing a single combination of wireless module and power supply module, a single system was implemented. METHODS: Currently in case of wireless transmission, it had various problems causing by some factors such as buildings, obstruction, and entanglement of wires and so on. In order to overcome problems of wireless transmission, a single combination module design was researched, which transmits vital signal and sign data using basic electric line installed in the inner building or between others. Even though it was also possible of wireless communication and the internet, in case of a power supply without them, it could be possible to transfer data to underground or top ground in the inner building without any special communication line. RESULTS: Bio signal data was transmitted through a power supply line, a noise problem occurred would be solved by the designed noise filter. The filter showed that noise was cut off about more than 90%. It was also confirmed that the used ECG signals was stably received on transmission experiment. An internal PCB antenna could make the system be wireless communication without the disclosure of an antenna. CONCLUSIONS: In this study, in order to implement a useful system transmitting bio signal and data through wire and wireless management for combination design of wireless module and electrical line module, bio signal transmission system was implemented by design of noise break filter circuit to reduce power noise and PCB internal antenna design.
