The safety of bamboo salt on human body was evaluated by a clinical study intended for 13 volunteers, who took 10 or 15 grams of bamboo salt daily for 8 weeks in addition to the regular dietary salt intake. Blood pressure and serum electrolytes(Na, K, Cl, Ca, Pi) were investigated. No significant changes of blood pressure were observed in 5 volunteers who took 10 grams of bamboo salt. The systolic and diastolic blood pressures measured before and after taking bamboo salt were at range of 115~140 mmHg and 75~101 mmHg, 118~144 mmHg and 75~104mmHg respectively. Blood pressures observed in 8 volunteers, who took 15 grams of bamboo salt, were also not significantly changed. The systolic and diastolic blood pressures of them were at range of 106~132 mmHg and 65~88 mmHg, 114~124 mmHg and 73~81mmHg respectively. The changes of Na, K, Cl, and Pi in blood serum were not also observed.

In this paper, a CMOS current-mode integrator adequate to design low-voltage, low-power and high frequency application circuit. The designed current-mode integrator has a new architecture that is simple. When the designed integrator is compared with typical current-mode integrator, the new integrator has lower power dissipation, lower chip size and higher frequency range. The results of PSPICE simulation using ORBIT company's 1.2㎛ CMOS n-well processing parameter shows that 1.2mW power dissipation for 3.3V power supply.

하폐수중의 아닐린의 생물학적 분해를 위한 Pseudomonas속 균주 MIDR-79의 분리 및 특성

이재완,이동희,방병호 한국상하수도학회 1989 한국상하수도학회지 Vol.2 No.1

A bacterium, MIDR-79. was isolated from river bed which utilizes aniline as sole source of carbon and nitrogen. It was identified as Pseudomonas species. Optimal temperature and pH for the biodegradation of aniline was 30℃ and pH6~8, respectively. The microorganism grew well and degraded aniline completely in the range of 10 to 35mM of aniline, but substrate inhibition was observed at the concentration of 40mM aniline. The enzyme system involved in aniline biodegradation was repressed by the readily utilizable carbohydrates and nitrite. Ammonia was released from aniline with resting cells and accumulated in the reaction mixtue. And aromatic compounds besides aniline such as phenol, catechol and resorcinol were assimilated by the microorganism.

Recently, we have used internal fixation with titanium miniplate which introduced by Champy in 1976 in facial bone fractures. In cases of mandibular fractures, particulary mandibular angle fractures, we usually underwent the open reduction extraorally. But extraoral approaches may leave scars and put the facial nerve at greater risk. So, we had undergone the intraoral approaches in 31 patients of mandibular angle fractures (male : 29, female : 2)> These patients visited in Wonkwang university hospital from October 1991 to June 1993. We got easy operation time as average 20 minutes than extraoral approach. And reduced the postoperative nerve injury(14.2%), but postoperative infection is 6.1% nearly as same as extraoral approach. TMJ problems after intraoral open reduction was similar to extraoral approaches.

돼지 아데노바이러스(PAV-3). 6618주의 EIB region이 包含되어 있는 map unit 4.0에서 9.7까지의 유전자에 대한 1,984 bp의 염기서열을 決定하였으며, 이 結果를 알려진 여러 아데노바이러스 유전자와 비교하여 다음과 같은 결과를 얻었다. 1. PAV-3의 EIB유전자는 10개의 ORF로 구성되어 있으며, 그 중 아데노바이러스의 단백질과 유사성이 있는 것은 ORF1, ORF2 및 ORF3이었다. ORF1은 Ad41의 19kd 와 BAV-2에서의 EIB ORF2에서의 아미노산의 一致率은 각각 32%와 31%이었다. 2. ORF2는 Ad2 55kd protein과 tupaia adenovirus 44kd protein가 각각 34%로 아미노산 一致率이 가장 높았으며, Ad41의 52kd protein. BAV-3의 EIB ORF3에서도 33%의 一致率을 보였다. 3. ORF1은 61-666 uncleotide (606 bp), ORF 2에서는 429-1,850 uncleotide (1,422 bp)의 부위로 각각 202, 474 a.a로 構成되었으며, 예상되는 분자량은 20 kd와 52 kd이었다. 4. ORF3는 hexon-associated pIX유전자로 추정되며 내부에 1개의 polyadenylation signal(ATAAA)이 1938-1942 uncleotide에 위치하였으며, 이 부위는 TATA box (1937-1942 uncleotide)와 중복되어 존재하였다. Porcine adenovirus type 3 (PAV-3) does not cause severe infection in pigs. Adenovirus has been suggestive of live vaccine vector carrying foreign gene. One of insertion regions is delayed early (EIB) region. However, EIB region of PAV-3 has not been molecularly characterized to date. Nucleotide sequence of EIB of PAV-3 was determined. The EIB region was composed of 1,984 bp and located between 4.0 and 9.7 map units. Three potential open reading frames(ORFs) with low level of homology to other adenoviruses and a polyadenylation signal were identified in the rightward direction of genome. The nucleotide and the predicted amino acid sequences of EIB were compared to those of human and animal adenoviruses. One of the three potential ORFs. ORF1 encoded a polypeptide homologous to bovine adenovirus type 2(BAV-2) ORF2 and human adenovirus type 41(Ad41) 19 kd protein. ORF2 encoded a polypeptide homologous to human adenovirus type 2(Ad2) 55 kd protein, bovine adenovirus type 3(BAV-3) ORF3 and porcine adenovirus type 4(PAV-4) ORF2. The predicted protein of ORF1 had homology to those of Ad41 and BAV-2 with 32 and 31% respectively, whereas the deduced protein of ORF2 had homology to those of Ad2. BAV-3 and PAV-4 with 34, 33 and 29%, respectively.
