  • In the Asian sub-continent Momordica charantia and Allium sativum are extensively used as food and are popular in herbal medicine. The two were screened against 15 pathogens and both exhibited broard spectrum antimicrobial activity. As compared to the standard antibiotics, M. charantia demonstrated broader and higher level of activity against most of the organisms. On the other hand A. sativum showed comparable activity to the standard antibiotics. Both M. Charantia and A. sativum are proposed as non toxic, safe, broad spectrum antibacterial agents.

  • 남태평양의 종주국이라고 할 수 있는 파푸아뉴기니의 기상환경은 고온다습한 열대우림기후로 작물의 생육에 아주 적합한 조건을 가지고 있어서 작물의 생산량을 증대시킬 수 있는 잠재력이 있는 천혜의 나라이다. 파푸아뉴기니 농촌 마을은 자급자족시대를 넘어 소득이 가능한 작물생산을 원하고 있다. 좋은 작물생산을 위하여 농업기상 환경을 이해하고 관수시설 설치 등 기술보급 등이 필요하다. 특히, 좋은 토양을 만들기 위하여 pH, EC, ORP 측정을 통한 개선이 필요하다. 농산물 시장은 급격히 현대화되고 있어 규격 생산, 소비자가 원하는 농산물 생산이 요구되고 있다. 파푸아뉴기니의 농업발전을 위하여 국제 기술협력이 요구되고 있는데 부존자원이 부족한 우리로서는 양국간 경제발전에 도움이 될 것이다. 특히, 파푸아뉴기니 농업개발을 위한 이 지역의 농업 기초 환경조사는 농업 기술협력의 큰 다리 역할을 하게 될 것으로 기대한다.

  • A number of Myristica species are used in herbal medicine for a variety of ailments. The methanol extracts of the leaves and the stem and root barks of Myristica subabulata were fractionated into petrol, dichloromethane and finally ethyl acetate. These were then screened against a total of 31 micro-organisms comprising of 13 G +ve, 12 G ve, one protozoa and 5 moulds. A broad-spectrum anti-bacterial activity was observed. As compared to fractionated the un-fractionated extracts exhibited much better level of activity.

  • After the virtual eradication of cattle during World War II, Papua New Guinea herds were rebuilt with Shorthorn and Aberdeen Angus cattle from Australia. These, and Red Sindhi and Sahiwal, imported in 1952, were considered unsuitable breeds. In 1954, Department of Agriculture, Stock and Fisheries imported three Brahman bulls and three heifers from Texas and in 1960 began importations of Afrikaner from Queensland. In Central Province, Brahmans were crossed with Angus and at Erap (Morobe) the hottest place in Papua New Guinea, Shorthorns were crossed with Afrikaners. In 1965, Brahman and Brahman-cross were sent to Erap. Records of breeding and growth rates were collected for use in upgrading in cattle of the basis of performance, not pedigree. The data are not ideal for genetic analysis, since no control groups were maintained. Birth weights (BWT), weaning weights (WWT) and calving intervals (CI) were analysed for the period 1969-1978. After exclusion of unsatisfactory data, 2,514 calf records were used, including both breeds from 1969 to 1973, but only Brahman-cross subsequently. Breed mean BWT ranged only from 30.6 to 33.8 kg. As Brahman content increased, BWT decreased and WWT increased; within a genotype, there was a negative maternal effect of high Brahman content on BWT and a positive effect on WWT which ranged from 138 to 174 kg. Afrikaner calves had heavier BWT but lighter WWT. As expected, bulls were heaviest, heifers lightest and mature cows bore and reared heavier calves. Calving interval (405 days, equivalent to 90% calving) was unaffected by breed but 4-year old cows averaged 423 days. Breed differences in BWT and WWT are consistent with the body of literature on performance of Brahmans and Afrikaners. Since cattle tick are not present and internal parasites are insignificant at Erap, the superiority of Brahmans indicates that they were better at utilizing the mediocre quality grazing of the Markham Valley or were more heat tolerant. Performance selection over ten years resulted in the virtual elimination of Afrikaners, with the final genotype approximately 9/16 Brahman, 3/8 Shorthorn and 1/16 Afrikaner.

  • Objectives This study was conducted to describe the regional malaria incidence in relation to the geographic and climatic conditions and describe the effect of altitude on the expansion of malaria over the last decade in Papua New Guinea. Methods Malaria incidence was estimated in five provinces from 1996 to 2008 using national health surveillance data. Time trend of malaria incidence was compared with rainfall and minimum/maximum temperature. In the Eastern Highland Province, time trend of malaria incidence over the study period was stratified by altitude. Spatio-temporal pattern of malaria was analyzed. Results Nationwide, malaria incidence was stationary. Regionally, the incidence increased markedly in the highland region (292.0/100000/yr, p =0.021), and remained stationary in the other regions. Seasonality of the malaria incidence was related with rainfall. Decreasing incidence of malaria was associated with decreasing rainfall in the southern coastal region, whereas it was not evident in the northern coastal region. In the Eastern Highland Province, malaria incidence increased in areas below 1700 m, with the rate of increase being steeper at higher altitudes. Conclusions Increasing trend of malaria incidence was prominent in the highland region of Papua New Guinea, while long-term trend was dependent upon baseline level of rainfall in coastal regions.

  • The Bismarck Sea represent a unique region in the equatorial western Pacific where one can explore the relationship between tectonic and magmatic processes associated with back-arc opening. The sea, located north of Papua New Guinea and just south of the equator, formed during the final stages of a long, complex geological development of the Melanesian Borderland. The development resulted from the Cenozoic convergence between the Australian and Pacific- Caroline Plates and the opening of back-arc basins. At present, the Bismarck Sea straddles two oppositely facing trenches, the inactive Manus trench and the active New Britain trench, and covers two basins, the New Guinea Basin (NGB) to the west and the Manus Basin (MB) to the east. The two basins are separated by the shallow Willaumez-Manus Rise (WMR), which trends roughly from WNW to ESE. The origin of these major structural units and their relationship with the presentday zone of major seismicity along the Bismarck Sea Seismic Lineation (BSSL) remains unclear and is the main focus of our study.

  • Thirty six crude drug samples have been prepared from different parts of twenty five plants belonging to different families, and antimutangenic activities were studied by using SOS chromotest (E. coli PQ 37). The following crude extracts of PNG medicinal plants which had a appreciable antimutagenic activity against mitomycin C were: Artocarpus communis (stem bark), Cycas circinalis (leaves), Merremia peltata (leaves), Intsia palembanica (leaves), Annona muricata (stem bark), and Artocarpus altilis (root bark).

  • In many parts of the world Allium cepa, Allium roseum, Trigonella foenum graecum and Curcuma domestica are extensively used as food and are popular in herbal medicine. The four were screened against 26 pathogens and all exhibited broad-spectrum anti-bacterial activity. The aqueous as well as fractionated methanol extract of Allium cepa and A. roseum demonstrated broader level of activity against most of the organisms. On the other hand the unfractionated methanol extracts as well as the fractions of both Trigonella foenum graecum and Curcuma domestica showed broad spectrum of activity. Fractionation was found to improve their level of activity. In both cases the ethyl acetate fractions exhibited higher level of activity. All the materials tested were inactive against any of the four moulds. Allium cepa, Allium roseum, Trigonella foenum graecum and Curcuma domestica are proposed as non toxic, safe, broad spectrum antibacterial agents.

  • Papua New Guinea(PNG)산(産) TAUN재(材)를 이용한 합판제조 조건을 확립하였다. Taunwo(材)는 목질(木質)이 다양(多樣)하고 건조후 함수 분포가 균일(均一)치 못하여 퇴적(堆積)양생시키므로써 적정 함수분포를 유지할 수가 있었다. 또한 조직이 치밀하여 접착제와의 친화성이 낮아 집착불량이 용이하게 발생되기 쉬운 재(材)이나 제호시 수지율을 높여 도포하므로서 접착불량을 제거할 수가 있었다. Taun재(材)는 lauan재(材)나 kapur(材)와 혼합접합(混合接合) 하여도 접착력은 양호한 결과를 보였다.
