The effects of Laminaria japonica fucoidan extract (LJFE) on the biochemical parameters of lipid-related function were investigated in liver and serum of CCl_(4)-treated rats. LJFE of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 14 days. On the day 15, 3.3 ml/kg of CCl_(4) dissolved in olive oil (1:1) was injected 12 hours before anesthetization. We examined the lipid-related functions and enzyme activitys by measuring the levels of total cholesterol (TC), triglyceride (TG), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in serum. The results showed that CCl_(4) treatment increased the high values of TG, LDH and ALP decreased the low values of TC but LJFE pretreatment decreased the high values of TG, LDH and ALP to the low values, increased the TC. It was suggested that LJFE can be used as the potential candidate for the lipid-metabolism natural supplement.

Although the importance of good conservation of historic sites including ancient royal tombs is well aware, still not much attention has been paid for the facilities and systems to preserve those historic sites, which includes precious artifacts as wall paints and carved works, etc. Even the general understanding about the environment of the underground space of tombs is not satisfactory. In Korea, researchers have recently begun addressing the above issue and are making efforts to develop suitable HVAC(heating, ventilating and air-conditioning) systems for conservation of tombs. An experimental investigation was carried out to study the behavior of the HVAC system installed for a tomb. This tomb resembles in size and shape the original stone built tomb of Baek-je Dynasty, which dates back to 6th Century in southwest part of Korean peninsula. In this study, an HVAC system for a tomb(D×W×H=1.3m×3.0m×1.2m) was installed to maintain sui표 indoor conditions for conservation of tomb. The temperature and humidity inside the tomb were measured different of the setting. Finally, performance of the HVAC system is presented and discussed.

A fourteen-month-old intact female Poodle was referred to the Veterinary Teaching Hospital, College of Veterinary Medicine, Chungnam National University. The patient was presented with history of vomiting, inappetence, ataxia, insomnia, tachypnea and convulsion for 5 days. Biochemical examination revealed BUN (254.2 mg/dl), creatinine (9.22 mg/dl) and phosphate (14 mg/dl). Epithelial cells of urinary tract, neutrophils, macrophages, a large number of gram negative and smaller number of gram positive bacteria were presented on urine test. Ultrasonographic findings show hyperechogenic kidney and indistinguishableness of renal cortex and medulla. Based on the results of examination described above, this case was diagnosed as acute renal failure with interstitial nephritis by urinary tract infection (UTI). Treatments with fluids therapy, diuretics, and peritoneal dialysis during hospitalization showed good results with no clinical signs.

In order to know the residual pattern of pesticides and predict to the degradation period until below MRL, we experimented procymidone and chlorothalodi for grape which were the most detected pesticide in grape by NAQS(National Agricultural product Quality management Service) survey. In this experiment, we sprayed those pesticides 10 days before harvest and analyzed 0, 1, 2, 3, 5, 7, 10 day sample to establish logical equation and to calculate DT_(50) Also the same day samples stored at 4℃ and 20℃, which were compared their degradation patterns. During the cultivating period, the residue amount of procymidone was changed from 1.85㎎/㎏(0day) to 0.33㎎/㎏(10days), DT_(50) was 3.5 days, and chlorothalonil was changed from 5.5 ㎎/㎏ (0 day) to 3.49 ㎎/㎏ (10 day), DT_(50) was 4.4 days. During the storage period, DT_(50) of procymidone and chlorothalonil at 49c were 10.5 and 7.6 days, and 6.3 and 6.1 days at 20℃, respectively.

Fifty-eight strains showing different colony morphological characteristics on various media were isolated from marine coral (Plexauridae sp.) and ambient seawater near Mun-Sum, Cheju-Island in 1998. Bacterial diversity was studies by phylogenetic analysis of the partial 16S rRNA gene sequences. All isolates representing the bacterial domain included affiliates of the high G+C (59%) and los G+C (3%) subdivision of Gram positive bacteria, and the alpha (33%) and gamma (5%) subdivision of the Proteobacteria. The 16S rDNA sequence similarity of the isolates was in the 88.3 to 100% range (average, 95.6%) to reported sequence data. In the comparison of the isolates from marine coarl and ambient seawater, more diverse groups belonging to ${\alpha}$-Proteobacteria were preferentially obtained from seawater.
