Among those cases, 6 were examined with CT, 4 with FFA and 8 with A/B-scan ultrasonography. Results showed that the characteristics of CT, A/B-scan ultrasonography and FFA in MGS included： （1） The attachment spot of optic nerve became thin and vitreous body protruded to the posterior wall of eyeball with a spherical shape on CT image; （2） in the early period of FFA, hypofluorescence appeared on the optic, the abnormal arteriae and veins around the optic papilla were displayed clearly and in the late period, optic disc was stained with fluorescein; （3） on B-scan ultrasonogram, the vitreous cavity extended to the posterior pole and optic papilla, and projected to the basal part of muscle cones and thus the posterior part of vitreous cavity looked like an upside-down bottleneck. Sometimes the echogenic band of retinal detachment could also be seen. On A-scan ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echoes and presented a base line without any evident wave crest. It is concluded that CT, A /B-scan ultrasonography and FFA could show the imageological features of MGS from different aspects, which helps clinicians to differentiate it from other diseases such as optic disc coloboma. CT and A /B-scan ultrasonography, in particular, are considered to be reliable imageological methods for the accurate diagnosis of MGS and are superior to the traditional techniques.展开更多

It shares borders with China on the north and Thailand on the east. Kengtung is a place which forms a significant historical site in the easternmost part of Myanmar. From the geopolitical point of view, the region was located in a most strategic place. Its situation forced to safeguard the region. The town lies on a critical point of Myanmar’s defences. The restriction of exacting money as a yearly tribute did not concern for Kengtung. The tradition of paying homage was appeased to the King. The ruling Sawbwa which achieved the valuable return presents of the Burmese King. Kengtung came in the first class, and was the most important of the Myanmar’s possessions east of the Thanlwin River. Its position may be roughly judged by the tribute paid to the King and the contigent it was bound to supply to the royal army. Therefore, Kengtung was very important for the security of Myanmar’s eastern frontier during the Konbaung period. It was like a small Union within an Empire together with multinational races of Myanmar. A good deed of past events blanket over the town till today.展开更多

Pigs were allotted to pens and randomly assigned to three dietary treatments: A) completed feed fed <em>ad libitum</em>;B) complete feed fed at 75% of intake of treatment A, and C) treatment B with <em>ad libitum</em> availability of morning glory. The design was a completely randomized design (CRD) with five pens (replications) of each treatment with four pigs per pen. Average daily feed intake (dry matter basis) was higher (P < 0.001) for pigs fed treatment A (1420 g/d) compared to treatment B (1048 g/d) as expected, with treatment C intermediate (1178 g/d;1048 g/d complete feed + 130 g/d morning glory). Average daily weight gain of pigs fed <em>ad libitum</em> was greater (P < 0.001) than pigs restricted fed with pigs which provide morning glory intermediate (871, 674 and 714 g, respectively). Feed efficiency improved (P < 0.024) for pigs fed the restricted feed level compared to pigs fed complete feed <em>ad libitum</em> or pigs restricted fed but provided morning glory (1.63, 1.56 and 1.65, respectively). For economics, feeding complete feed <em>ad libitum</em> improved (P < 0.001) income over feed cost compared to restricted feeding or providing morning glory (USD 41.48, 33.42, and 33.89/pig, respectively). In conclusion, feeding growing pigs a complete diet <em>ad libitum </em>resulted in the greatest growth rate and profitability. Offering morning glory <em>(Ipomoea. aquatica</em>) to pigs fed a restricted level of complete feed did improve final body weight, but the extra cost of feeding morning glory offset this advantage resulting in similar profitability on an income over feed cost basis.展开更多
