A dog with a history of long-term phenobarbital administration presented to Seoul National University Hospital for Animals with clinical signs of footpad ulceration and facial ulcerative dermatitis. Skin lesions (facial/footpad dermatitis), histopathologic signs (parakeratotic hyperkeratosis, edema and hyperplasia of the epidermis), and liver involvement (increased plasma liver enzymes and nodular lesions) suggested a diagnosis of superficial necrolytic dermatitis (SND). The patient died suddenly at home of unknown cause after 8 months medical treatment, but intravenous amino acid supplementation and supportive hepatic medication proved as effective for the skin conditions.

Improvement of cold-tolerance of Italian ryegrass(Lo1ium multiflorum L.) is an important breeding objectivefor enlargement of cultivation area in Korea. To develop the cold-tolerant variety of Italian ryegrass,cold-tolerant clones survived under - 13- - 14$^{\circ}$C of minimum average air temperature in January wereselected in the area of Dun Nae, Kwangwon Province. The 5 lines of Italian ryegrass clones selected werepolycrossed for seed production. Synthetic seeds were examined on growth characters and forage productionsin Suwon from 1996 to 1998, in Unbong 1997 and in Younchun 1998, respectively. The growth charactersand forage productions of Italian ryegrass variety named as "Hwasan 101" were summarized as follow ;ltalian ryegrass variety, Hwasan 101 was tetraploid and showed semi-prostrate growth habit in autumn andwas not only dark green in leaf color and broad in flag leaf width but also excellent in leafiness. Also, itshowed low plant height at first heading date of 20th May and excellent lodging tolerance. Expecially,Hwasan 101 in all trial regions was 80 -90% of winter survivals that was higher than 60 -90% of Florida80 and Marshall varieties. Therefore we estimate that Hwasan 101 can be cultivated in regions that is higherthan -9$^{\circ}$C in minimum average air temperature and lower than 400m in sea level. In forage production ofHwasan 101, fresh weight and total digestible nutrient(TDN) yield were 66,940 and 6,551kghq and drymatter yield was 10,050kgha. In conclusion, Italian ryegrass, Hwasan 101 was medium and late maturingvariety but excellent in cold-tolerance, lodging-tolerance, leafiness, and forage production.(Key words : Italian ryegrass, Cold tolerance, New variety)ian ryegrass, Cold tolerance, New variety)

Prostitutes living in Songdo beach in Pusan, for two years period (from September 4, 1964 to August 28, 1966) were investigated for the present status and Venereal Diseases. The following results were obtained. 1. Age distribution:The youngest was 18 years old and the oldest 29. The group between 22-25 years old was 72.8%, approximately three fourth of all prostitute. 2. Educational background: From illiterate to college graduated. The group of graduated primary school was 80.7%, approximately four fifth of all prostitutes. 3. Distribution of birth places: From all cities and provinces in Korea except Chejudo Island province. Kyongsang Namdo province was highest(24%), Kyongsan Pukdo province 18%, Pusan city 12%, and Seoul city 11%. 4. Monthly and weekly Venereal Diseases examination to prostitutes: Total examined cases were 7757, consisting of 323 monthly, and 75 weekly. Total numbers of disqualified persons were 592(7.63% of total examined), consisting of 25 monthly, and 6 weekly. 5. Clinical and laboratory findings of the rejected prostitutes at the Venereal Disease examination: Among total cases of rejected 592, gonococcal positive cases were 2.89%, staining by gram's method, cervical erosions 3.53%, and numerous pus cells but gonococcal negative 1.53%. 6. Seasonal distribution of prostitutes : Songdo beach is one of the famous sea shore sightseeing resort in Pusan. Therefore, numbers of prostitutes were increasing in hot season, summer and decreasing in cold season, winter. 7. Number of disqualified prostitutes at the Venereal Disease examination by seasonal trend: In autumn 18.04%, winter 8.68%, spring 5.85%, and summer 4.43%, in order as described, the decreasing tendency was observed. 8. Serolgical tests for syphilis: VDRL slide method and Kolmer-Wassermann reaction were performed to the prostitutes. STS were positive by VDRL slide method in 8.33-33.87%, Kolmer-Wassermann reaction in 8.33-27.42% of the prostitutes. The results of sero-positive of syphilis showed tendency toward gradually increase from 1964 to 1966. 9. Authors were observed only 1 case or soft chancer, but neither lymphogranuloma venereum nor granuloma inguinale were detected.

Objectives : Weights and measures (度量衡) in Korean traditional medicine have been changed in many dynasties and countries. Thus, measurements of chon (寸) and cheok (尺) have been considered as symbolical meaning in recent studies on meridians and acupoints. The present study was made to settle up standard measurement by surveying length of each parts of upper limb as follows. Methods : To calculate length of 1 chon (寸), the length of each part was divided into the numbers of chon (寸) as shwon in ${\ll}$Goldo Hwangjenaegyeong-yeongchu (靈樞 骨度篇)${\gg}$; the chon (寸) length in ${\ll}$Goldo Hwangjenaegyeong-yeongchu (靈樞 骨度篇)${\gg}$ was compared with the chon (寸) length which is calculated by dividing human average hight into 75 chon. Results : Increment of length of 1 chon (寸) did not change as increment of height in subjects. Length of 1 chon (寸) in height is representative of length of 1 chon (寸) in each parts of upper limb. Conclusions : We suggest that most suitable length of 1 chon (寸)for the standard measurement of acupoint location is 2.20 ${\pm}$ 0.17 cm based on length of elbow joint to wrist joint.

"Hwasan 103" is a new cold-tolerant Italian ryegrass(Lo1ium multiflorum L.) variety developed by theNational Livestock Research Institute(NLR1) in 1999. To develop a cold-tolerant variety of Italianryegrass(Lo1ium multiflorum L.), cold-tolerant clones survived under - 13 - - 14$^{\circ}$C of minimum average airtemperature(MAAT) in January were selected at Hwachun, Kwangwon Province in 1995. Five clones ofselected clones were polycrossed for seed production by NLRI, RDA in 1996."Hwasan 103" was diploid variety, green in leaf color and broad in flag leaf width. Also it hassemi-prostrate and medium growth habit in late autumn and in early spring, respectively. "Hwasan 103" wasexcellent in lodging tolerance at harvesting time. First heading date of "Hwasan 103" was 14th May, it wassimilar to that of Marshall. Expecially, "Hwasan 103" survived about 50-70% under - 10- - 12'C ofMAAT in January, so it could be cold-tolerant variety that can be safely cultivated in regions higher than -9$^{\circ}$C of MAAT in January. Compared with Marshall "Hwasan 103" showed 3% higher fresh yield (57.8MTper ha) and it showed 2% higher dry matter yield (11.OMT per ha). Higher IVDMD and TDN and lowerADF and NDF were observed in "Hwasan 103" than those of Florida 80 and Marshall in Forage quality.(Key words : Italian ryegrass, Cold tolerance, New variety "Hwasan 103")all in Forage quality.(Key words : Italian ryegrass, Cold tolerance, New variety "Hwasan 103")n 103&")ot;)

This study was conducted to obtain the transformed alfalfa (Medicago sativa L.) plants with thermotolerance gene (BcHSP17.6) using Agrobacterium tumefaciens LBA4404 and we confirmed the transformed gene from the regenerated alfalfa plants. The expression vector, pBKH4, harboring BcHSP17.6 gene was used for production of transgenic alfalfa plants. In a process for transformation, the callus of alfalfa was cocultivated with Agrobacterium tumefaciens and transformed calli were selected on kanamycin-containing SH-3-kc medium to regenerate into into the plant. The complete transgenic alfalfa plants were produced by cultivation for about 4 months on several regeneration media, SH-nk-c, SH-l lb-c, SH-sp-c, and SH-IBA. The transgenic alfalfa plants were analyzed by isolation of genomic DNA and PCR/Southem blot.
