A two-year-old male peacock (Pavo cristatus) showed acute watery green diarrhea, followed by neurological signs including torticollis and muscular tremor. By the hemagglutination inhibition test for detecting the antibody against the Newcastle disease virus (NDV), the peacock serum inhibited the agglutination of chicken red blood cells. Grossly distinctive hemorrhagic lesions were found in the mucosa of proventiculus and intestine and lung. The spleen revealed multiple variable sized necrotic foci. Histologically, the mucosa of gastrointestinal track had hemorrhagic lesions and some of them underwent ulceration. The spleen exhibited multiple variable sized necrotic foci in which fibrin exudation was marked. Central nervous system had mild non-suppulative menin-goencephalitis consisting of vasculitis, perivascular hemorrhage, gliosis and meningitis. The cells particularly in the cerebellum were degenerative to necrotic. Some of these nerve cells revealed characteristic peripheral chromatolysis. From the present serological and pathological findings, it is suggested that NDV causing death of peacock was velogenic viscerotropic strain. This is the first report of the occurrence of velogenic viscerotropic NDV in an adult peacock in Korea.

Photosensitization occurred in a 4-month old Holstein calf soon after going onto the pasture lush with green Japanese millet(Echinochloa crusgalli). Skin lesions were restricted to the unpigmented white area of skin. They were most pronounced on the dorsum of the body, diminishing in degree down the sides and were absent from the ventral part. The demarcation between lesions and normal skin was clearcut. There were edema, exudation and sloughing of affected skin on the left gluteal region, and erythema, edema and scab on right scapular region. Interception of the light, discontinuance of Japanese millet ingestion, and the administration of antihistamine and penicillin made the calf rapid recovery. This disease was considered photosensitization due to chlorphyll in ingested Japanese millet.

Allelopathy is an ecological phenomenon that refers to the beneficial or harmful effects of one plant on another plant, both crop and weed species, by the release of organic chemicals (allelochemicals) from plant parts by leaching, root exudation, volatilization, residue decomposition in soil and other processes in both natural and agricultural systems. Allelopathy can affect many aspects of plant ecology including occurrence, growth, plant succession, the structure of plant communities, survival, dominance, diversity, and plant productivity. In this review, we describe the concept of allelopathy, some mechanisms of operation within plants and then focus on a select number of gymnospermous tree genera: Ephedra, Pinus, Taxus, Cedrus, Juniperus, Picea, Cunninghamia and Araucaria. Pinus, Taxus (yew) and Cedrus (cedar) trees have a strong negative allelopathic effect on the germination, growth, or development of other plant species in the forest community.

The anti-inflammatory activity of SEO-KYONG-TANG extract(SKTWE) was examined by using carrageenin- and acetic acid-induced edema, croton oil-induced granuloma pouch, and adjuvant arthritis in rats. In addition, the acute toxicity, analgesic and antipyretic effects of SKTWE were investigated by using general experimental methods in mice. SKTWE did not show acute toxicity at 2400 mg/kg(p.o.) nor 1200 mg/kg(i.p.). After oral administration of the SKTWE to rats, significant anti-inflammatory activity was observed on 1% carrageenin- and 5% acetic acid-induced edema. Also, it significantly inhibited granuloma and exudation in these. In the adjuvant arthritis experiment, the SKTWE decreased the hind paw edema after 3 days of oral administration. In addition, it inhibited the writhing syndromes induced by 0.7% acetic acid in mice. The antipyretic activity of SKTWE was also observed through the typhoid vaccine experiment. These results suggest that SKTWE has analgesic, anti-inflammatory and antipyretic action.

This study was carried out for deresinning the larch boards dried in a conventional kiln. Prior to heat treatment they were steamed in an autoclave for 5 hours or frozen for 24 hours at a temperature of $-35^{\circ}C$. The velocities of ultrasound transmitted through the specimens were measured to examine the correlation with their resin contents. It was found that the specimens heated at $100^{\circ}C$ for 5 hours contained less resin that those heated at $200^{\circ}C$ for an hour. Both treatments of steaming and freezing were effective for deresinning and the former was better than the latter. The ultrasonic velocities measured before the heat treatment showed a negative correlation to the resin contents of the specimens, but those measured after the heat treatment a positive correlation. This difference may be attributed to the viscosity of resin.

In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxauiol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

To obtain the genetic information about DVT( $\alpha$- and $\beta$-4,8,13- duvatriene-1,3-diols) and cis-abienol contents, two burley(Burley 21, KB 108), three sun-cured cultivars(N. tabacum L. cv. Yonbyun 3, Jahengyon and Jaraehong), TI 1068, and thirty F$_1$ hybrids derived from them were sampled and the diterpenes were analysed using thin layer chromatography (TLC) procedures. DVT exudation from the leaf scerface could Ie detected in all coltivars and F$_1$ hybrids tested. TI 1068 and Yonbyun 3 had cis-abienol exdudates. Burley 21, KB 108, Jaheungyon, and Jaraehong had no spot of cis-abienol. It is considered that cis-abienol exdudation might be controlled by dominant gene(s). The cytoplasmic effect on the cis-abienol exdudation was not detected.

A dead nine-month-old female hooded crane (Grus monachus) fecund in Chonnam province was examined pathologically, bacteriologically and toxicologically. Pathologically multiple necrotic foci consisting of infiltration of heterophil, lymphocytes and macrophages, and exudation of fibrin were observed in liver. Kidney had multiple hemorrhagic foci. Aeromonas hydrophila identified by biochemical properties was isolated. Phosphamidon, a kind of organophosphate, was detected massively in feed content of gizzard. From these results, lethal ingestion of phosphamidon was a causative agent of death. In addition, future study has to be done about correlation between liver necrosis and A. hydrophila infection.

뇌 유구낭미충증의 진단에는 혈청뿐만 아니라 뇌척수액내 특이 IgG항체가도 측정하여 혈청학적 진단의 민감도를 약 10% 높일 수 있다. 이 경우 뇌척수액내 특이 IgG항체가 그 환자의 혈청에서 혈관-뇌 장벽을 넘어 이전된 것인지 또는 두개강내 병변에 형성된 육아종에서 생성한 것인지를 결정하는 일은 뇌척수액내 특이 IgG항체가 측정의 의미를 부여하는 데에 중요하다. 이 연구는 그 기원을 찾기 위하여 실시하였다. 확진된 뇌 유구낭미충증 환자 82례와 기타 신경계질환 환자 및 건강대조인 45례에서 오은 혈청과 뇌척수액에서 각각 총단백질, 알부민 및 IgG 농도를 측정하였다. 그리고 Tourtellotte and Ma (1978)의 공식에 의하여 뇌척수액내 IgG농도를 여출(濾出, transudation; 혈관-뇌장벽이 정상인 상태에서 생리적으로 뇌척수액으로 이전된 것), 삼출(渗出, exudation; 혈관-뇌장벽이 파괴된 상태에서 병적으로 이전된 것) 및 두개강내 생사 등 세가지 기원으로 분리하였다. 고리고 혈청 및 뇌척수액내 특이 IgG항체가를 효소 면역측정법으로 측정하였다. 뇌척수액내 특이 Ig9G항체가와 각기원별 IgG량과의 관계를 통계학적으로 검정하였다. 그 결과를 요약하며 다음과 같다. 1. 뇌 유구낭미충증 환자 뇌척수액에는 총단백질, 알부민 및 IgG평균치가 상승되어 있었다. 각 단백질 농도는 혈청내 특이 IgG항체가와는 관계없이 뇌척수액내 IgG항체가 양성자에서 높았다. 2. 뇌 유구낭미충증 환자의 뇌척수액내 IgG량(14.0mg/dl)은 여출(4.52mg/dl), 삼출(2.94mg/dl) 및 두개강내 생산(6.88mg/dl)으로 구성되었다. 뇌척수액왜 특이 IgG항체가는 여출 및 삼출에 의한 IgG양과는 통계학적 유의성이 없는 관계이었으나 두개강내 생산량과는 유의한 관계가 있었다. 3. 제 4뇌실에 병 변이 화인된 뇌유구낭미충증 환자의 측뇌실에서 얻은 뇌척수액에는 총단백 질, 알부민 및 IgG량이 정상범위이었고 특이 IgG항체는 음성이 었다. 같은 환자의 요추천자로 얻은 뇌척수액에서는 각 단백질이 상승되어 있었고 특이 IgG항체가는 양성이었다. 4. 뇌 유구낭미충증 환자의 뇌척수액내 EgG량중 삼출에 의한 양이 증가된 예에서는 대부분 두개강내 IgG생산이 동반되고 있었다. 따라서 삼출에 의한 뇌척수액내 IgG 출현은 뇌유구낭미충증의 진행중 어느 시기에 특히 심한 것으로 추정된다. 이상의 결과에서 유구낭미충증 환자의 뇌척수액내 특이 IgG항체는 두개 강네 병변에서 생산된 것임을 알 수 있었다. 따라서 뇌척수액을 이용한 특이 IgG항체 측정은 진단에 도움이 된다고 생각된다.

Debridement is a crucial component of wound management. Recent technologies such as hydrosurgery (Versajet), ultrasound therapy (the MIST therapy device), or plasma-mediated bipolar radio-frequency ablation therapy (Coblation) seem to represent interesting alternatives for wound debridement. The purpose of this systematic review was to describe, evaluate, and compare these three recently developed methods for the management of chronic wounds. In January 2016, an electronic database search was conducted of MEDLINE, PubMed Central, and Embase for articles concerning these three innovative methods for the management of chronic wounds. A total of 389 references were identified by our search strategy, and 15 articles were included. We extracted data regarding the number and age of patients, indications, operating time, number of procedures, costs, wound healing time, decrease in exudation, perioperative blood loss, bacterial load, and the occurrence of complications. The 15 articles included studies that involved 563 patients who underwent hydrosurgery (7 studies), ultrasound therapy (6 studies), or Coblation (2 studies). Six randomized controlled trials were included that compared the use of a scalpel or curette to hydrosurgery (2 studies) or ultrasound therapy (6 studies). Hydrosurgery, in addition to being a very precise and selective tool, allows significantly faster debridement. Ultrasound therapy provides a significant reduction of exudation, and improves the wound healing time. No comparative study dedicated to Coblation was identified. Despite the obvious clinical interest of the topic, our review of the current literature revealed a lack of prospective randomized studies comparing these devices with each other or with standard techniques, particularly for Coblation and hydrosurgery.
