We investigated the effects of single and combined administrations of Lactobacillus species (L. plantarum, LP; L. gasseri, LG; L. casei, LC) on blood lipid metabolism and obesity in mice fed a high-fat diet (HFD). The mice were continuously supplemented with LP, LP/LG, or LP/LG/LC, along with HFD, for 12 weeks. The consumption of HFD led to significant increases in body weight, total cholesterol, and triglyceride levels compared to the normal control group. However, administration of LP, LP/LG, or LP/LG/LC to HFD-fed mice reduced body weight gain and showed a tendency to suppress the levels of total cholesterol, triglycerides, and LDL-cholesterol, while increasing HDL-cholesterol levels. The HFD group exhibited increased abdominal fat weight and larger adipocytes in the epididymal adipose tissue compared to the NC group. However, the administered probiotics led to a significant reduction in adipocyte size with decreasing tendency in abdominal fat weight compared with the HFD group. Additionally, the deposition of giant vesicular fat cells in the liver of the HFD group considerably decreased in the probiotic-administered group. Microbiome analysis revealed an imbalance in intestinal microbes in the HFD group, characterized by lower Bacteroidetes and higher Proteobacteria ratios. However, probiotic administration tended to restore the microbial distribution by controlling the abundance of Bacteroidetes and Proteobacteria, resulting in decreased Firmicutes/Bacteroidetes and Proteobacteria/Bacteroidetes ratios. These results suggest that single and combined administration of LP and other probiotics holds enormous potential in reducing obesity in HFD-fed mice as they regulate lipid metabolism, reduce adipocyte size, and restore the balance of intestinal microbes.

Si incorporated diamond-like carbon (Si-DLC) films ranging from 0 to 2 at.% contents were deposited on STS 316L substrates for orthopedic implants by means of r.f. plasma-assisted chemical vapor deposition (r.f. PACVD) technique, using mixtures of benzene ($C_6H_6$) and silane ($SiH_4$) as the precursor gases. This study provides the reliable and quantitative data for assessment of the effect of Si incorporation on corrosion property in the simulated body fluid environment through the electrochemical test. It was found that corrosion to resistance of Si-DLC coatings with increasing Si content are improved owing to high $sp^3$ bonding.

A single specimen of Albula leptocephalus (55.7 mm SL) was collected from the southern coastal waters of Korea using an aquatic lamp. It is characterized by having a ribbon-like body with a small head and a well-forked caudal fin. Although the general appearance was similar to the leptocephalus of A. vulpes including myomere counts and fin ray counts, the melanophore deposition was different from that of A. vulpes. This leptocephalus specimen was confirmed with A. forsteri using the cytochrome b mtDNA (Cytb) analysis. The genetic distance of Cytb between the present leptocephalus and A. forsteri is 0.006-0.038, which falls into the cutoff point separating Albula species into eight deep lineages including the four valid species. Its genetic characteristic have more similarities to those of Fiji than those of Hawaii and the Northern territory of Australia.

The pattern of seed storage protein, vicilin, deposition and site of intracellular localization was examined in cotyledon cells of pea (Pisum sativum) seed using the immunocytochemical methods. The vicilin was confined to the cisternae fo the rough endoplasmic reticulum and dictyosome as well as protein granules newly formed in rough endoplasmic reticulum. Vacuolar protein deposites and protein bodies were also labelled by gold particles. After small protein bodies were formed in the rough endoplasmic reticulum, they were transported to large protein bodies and then fused together. Electron dense protein granule, elaborated in the dictyosome, appears to be transported from dictyosome to protein body. A few unlabelled protein granules seem to be accumulated in other type of proteins than vicilin.

Solitary fibrous tumor is a spindle cell neoplasm that can arise in any place of the body. Intracranial solitary fibrous tumors are rare. To our knowledge, only 57 cases with intracranial lesion have been reported. In Korea three cases have been reported. Our case was a 23-year-old woman who presented with morning headache. MRI showed a large intra-axial mass involving falx with typically isointense and heterogeneous strong enhancement on T1 weighted image in the right parieto-occipital region. Histologically the tumor showed spindle shaped cells within matrix with thick collagen deposition, hypercellularity, focal necrosis, and pleomorphism. Immunohistochemical study demonstrated diffuse positivity for CD34, Vimentin, Reticulin. In case of the intracranial tumors involving the meninges, we also should consider the solitary fibrous tumor with immunohistochemical staining for accurate diagnosis.

The shoulder is the most common site in the body for calcific deposition. Calcific tendinitis is one of the common lesions of the painful shoulder. The surpaspinatus tendon is the most frequently affected location, next the infraspinatus and relatively rare the subscapularis tendon. We report upon a case of calcific tendinitis of subscapularis tendon alone, which developed in a 61-year-old female after minor trauma and was treated successfully with surgical excision.

Biotechnology will play critical role in improving animal productivity. Animal growth rate and muscle deposition potential can be greatly improved by the application of biotechnology and biotechnological products. Administration of recombinant somatotropin (ST) or other compounds such as IGF-1 and growth hormone-releasing peptides (GHRPs) can enhance growth rate and carcass lean percentage. Gene transfer offers a powerful approach to manipulate endocrine system and metabolic pathways toward faster growth and better feed efficiency. Biotechnology is also extensively used for improving metabolism and activity of gut microorganisms for better nutrient digestibility. Knockout of growth-inhibiting genes such as myostatin results in considerable acceleration of body weight and muscle growth. Animal growth can also be improved by the use of gene therapy. Immunomodulation is another approach for efficient growth through controlling the activity of endogenous anabolic hormones. All the above aspects will be discussed in this review.

The depositional environments of the Pyung-Ahn Group sedimentary rocks, Jeongseon-Kun, Kangweondo, Korea are investigated. The environments are understood to be characteristic transitional from a typical shallow marine to a typical continental environment. Such transitional conditions are also understood in various parts of Quaternary and modern environment on the earth. In particular, the absence of detrital feldspar sand grains in the Manhang and Keumcheon Formation Sandstone body is described firstly in Korea, and the fact and possible mechanism are discussed.

대기오염물질의 침적현상은 대기 중에 부유하는 독성물질의 거동에 영향을 미치고 대기오염물질이 대기로부터 수면 또는 지표로 이동하는 주요 경로이며 이로 인하여 식물성장에 대한 피해 및 토양오염, 수질오염을 야기시키는 등 환경에 주는 영향으로 인하여 그 중요성과 관심이 증가되고 있다. 대기침적현상에 의한 수체(water body)의 영향정도에 관한 연구결과에 의하면, 미국의 5대호에 있어서 납 총량의 95％ 이상이 대기로부터 기여되고 있으며, 미국동부의 체사피크만(Chesapeake Bay)의 경우 적조현상의 원인물질로 알려진 질소에 대한 대기 기여도가 25∼40％에 이르고 있는 것으로 보고되고 있다.(U.S.EPA., Report 1991)(중략)

Amyloidosis is a diverse group of disorders that share the deposition of amyloid protein in various extracellular tissues. Systemic amyloidosis may involve any body part and about 9-15% of it is localized. In the head and neck, the larynx is known as most common involved site. A histological diagnosis of amyloidosis is necessary to establish a definite diagnosis. Conservative surgery can be done for relieved airway obstruction or restored voice. We present three cases of patients with laryngeal amyloidosis that was treated with laryngeal microscopic surgery with laser.
